1293644 A7 ____ B7______ V. INSTRUCTION DESCRIPTION (i) [Technical Field] The present invention relates to a method for treating biomass which is used as a carbon source in a coke dry quenching apparatus. [Legal Background] Development and practical use of new energy, conversion of energy generated by low carbon dioxide, improvement of atomic energy ratio, efficient and rational use of original primary energy, and utilization of unused energy or waste energy The problem of coping with the global warming effect is continuing. In particular, the meaning of the international convention reached by the Kyoto Convention (C0P3, The 3rd session of the Conference Of the Party) is also positively used to replace oil, coal, etc. Resources. Biomass is a general term for biomass, and according to FAO (Food and Agriculture Organization of the United Nations) can be divided into agricultural (wheat, sugar, rice bran, grass, etc.), forestry (paper waste, timber waste, thinning wood, firewood, etc.) ), livestock (livestock waste), aquatic products (aquaculture processing residues), waste (food waste, RDF (Refuse (j Derived Fuel), Tingmu, construction waste, sewage sludge), etc. The 'coke furnace is an external heating furnace. In order to improve the thermal efficiency, it is necessary to increase the size of the energy-saving technology or to develop the energy-saving technology in the past. It is a very advanced equipment for energy recovery technology. The main way of energy recovery technology for coke sensible heat In order to use a Coke dry quencher (hereinafter referred to as "CDQ"), a large-capacity circulating gas (mostly nitrogen) is used to cool the anomaly, and steam is generated by the heat of the circulating gas. The steam turbine paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) (please read the notes on the back and fill out this page), OK | -4- 129 3644 A7 _______B7 V. INSTRUCTIONS (2) Perform the action and recycle it as electricity. (Please read the note on the back and fill out this page.) The method of using the coke dry quenching device to treat the biomass is based on coke dry. A method of thermally decomposing a raw material (a sewage sludge cake) into a furnace chamber of a quenching unit before being cooled, for example, as disclosed in the Patent No. 2 7 9 9 8 8 of the invention patent. The thermal decomposition treatment method disclosed in Japanese Patent No. 2789988 utilizes the sensible heat of red hot coke, and thermally decomposes the organic components of the sewage sludge cake in the pre-furnace chamber, and simultaneously makes the moisture in the sewage sludge cake and the red hot coke. Water gasification reaction, producing combustible gas such as C0, h2, and introducing the gas into the flue, introducing combustion air into the flue and burning it. In the flue of the coke dry quenching device, the gravity sedimentation type called the dust collector The solid-gas separation mechanism is provided for protecting the boiler. The gravity-removing solid-gas separation mechanism uses the inertial force of the solid to make it settle, because the gas flow is disturbed When flowing, it will hinder the inertial force of the solid, and the efficiency of solid-gas separation will be significantly reduced. Therefore, in the flue of the coke dry quenching equipment, the gas flow rate is minimized to maintain the gas in a laminar flow state. It is very difficult to mix the combustible gas with the combustion air in the flue and burn it in the flue, and because the residence time is also short, the combustion amount is limited. Moreover, when the combustible gas is not completely burned and remains, Corrosive components such as H2S are generated, and metals such as boilers and cooling towers are corroded and cause large equipment failures. In waste materials such as wood and sewage sludge cakes, there is a component called fixed carbon. In the case of an oxygen-free atmosphere, when the raw material is thermally decomposed, it is a carbon component which is a residue of solid carbon without gasification. This paper scale applies to China National Standard (CNS) A4 specification (210X297 public) 1293644

V. INSTRUCTIONS (3) The general biomass contains about 20% by weight of fixed carbon. When the biomass is thermally decomposed in the furnace chamber before the coke dry quenching device, if there are many fixed carbon components in the biomass, it becomes dust and is introduced into the flue together with the combustible gas. As described above, since the combustion efficiency in the flue is extremely poor, the scattered dust (solid smectite) is not burned and collected by the dust collector, so the calorific value of the combustion of the fixed carbon component is not effectively utilized. The calorific value of the fixed carbon component is very high because it is all carbon, and accounts for about 4% of the calorific value of the biomass. In addition, due to the recent C〇2 reduction requirements, in coke ovens, the increase in coke yield or the energy saving requirements of coke oven related equipment is increasing. At present, heat recovery only leaves low-temperature heat rejection that is difficult to recover from heat. There is no epoch-making energy-saving equipment and co2 reduction equipment. One of these δ is a technique for the stabilization of a gas component, and the technique is disclosed in Japanese Laid-Open Patent Publication No. Hei 6-336588, No. 7-145377, and No. Hei 7-242879. In the middle, there is a disadvantage of reducing the coke yield due to the introduction of air into the furnace chamber.

[Invention] The present invention is directed to agricultural, woody, and waste-based raw materials. In the present description, the definition of the biomass is defined by the above-mentioned FA〇, that is, the agricultural germplasm of the farm is referred to as the straw, the sucrose, the rice bran, the grass, and the like. In addition, 'the so-called woody germplasm system refers to forestry biomass and waste-based biomass in the definition of FA〇, which is equivalent to paper waste, timber waste, thinning wood, firewood, and wood. Construction waste such as wood. The use of these systems is because the water content is small (9 to 50%) and the amount of heat generation based on the water content is also high. Therefore, it is possible to recover only gas or solid energy exceeding the necessary amount of heat in the dry distillation by the sensible heat of the red hot coke. This paper scale applies to China National Standard (CNS) A4 specification (210X297 mm) -10- 1293644 A7 ---~---- B7 V. Invention description () 8 (Please read the note on the back and fill out this page. The raw materials other than agriculture and wood are equivalent to kitchen waste, RDF (recycled fuel), sewage sludge, waste plastic products, and wastes that are not included in wood waste. Domestic animal waste, aquatic products, aquatic processing residues, etc., basically can be an effective energy source as long as the heat of the base water content exceeds the heat of vaporization of the water + the sensible heat rise of the biomass itself + decomposition heat. When the biomass is put into the CDQ, the sensible heat of the red hot coke can be used to remove the volatile component. In the pre-furnace chamber, the air is entrained by the coke input, or the air is optimized for the gas property, and there is air, and at the temperature of the red-heated coke, the carbon in the pre-furnace chamber (volatile matter, coke) , biomass) reacts with air. In the present invention, since the thermal decomposition (volatilization) reaction of the biomass in the pre-furnace chamber is earlier, the biomass is preferentially reacted with air to replace the coke which has been previously reacted (burned) with air. Moreover, when there is no amount of air necessary for the full amount of combustion in the pre-furnace chamber, or coke or biomass is periodically input into the pre-furnace chamber, and the coke or biomass previously injected is in the pre-furnace chamber. When the gas or air is cut off, the pre-furnace chamber will become a reducing gas layer without oxygen at an early stage. Under the gas layer, the unreacted biomass is thermally decomposed (dry distillation) to generate a gas, and at the same time, a solid component having a large carbon component is produced. Biomass residue is flammable and flammable, and other properties are not inferior to coke, so it can be used as coke. Therefore, the use of biomass can increase the solid content from the raw material. This paper scale applies to the Chinese National Standard (CNS) A4 specification (210X297 mm) -11-1293644 A7

V. INSTRUCTIONS () 9 Charcoal is awkward, so as long as the amount of coke required is constant, the composition and coke production from coal can be reduced. In order to make the effects and effects of the present invention more apparent, first, a general operation example of CDQ is shown in accordance with FIG. After the coke oven of about 8 〇〇 to 1 〇〇〇 C manufactured by the coke oven is propelled by the propeller and transported to the cdq equipment, the upper cover of the CDQ equipment is opened and then placed in the pre-furnace chamber 2. The portion where the upper cover 1 is closed is regarded as the upper coke input port. The high temperature coke 3 charged into the pre-furnace chamber is gradually cooled by the circulating gas 4 and cooled to about 200. (: The heat is heat-recovered in the heat exchanger 5 (boiler) by the cyclic rolling body containing nitrogen as a main component, and the steam turbine 6 is operated to generate electricity by the steam produced by the heat. At this time, in order to make residual volatile components, etc. Or the broken coke reaches the heat exchanger without causing problems such as coking or heat transfer inhibition. 'Air 9 (outside air) is added to the vicinity of the annular duct 8 of the gas discharge port discharged from the pre-chamber 2 to completely burn it. Further, in the pre-furnace chamber, air is injected into the air inlet port (see FIG. 2) provided in the pre-chamber chamber 2, and the air component and the carbon component in the pre-chamber 2 (the volatile component generated by the coke, The powdery coke and the bulk coke are reacted to generate carbon dioxide and water. The amount of air to be injected from the air inlet is not particularly limited as long as it is an air intake amount required for optimizing the gas properties generally performed. The generated carbon dioxide and water further react with the surrounding carbon components to become carbon monoxide and hydrogen, and merge with the circulating gas 4 to completely burn the annular conduit 8 and then serve as a high temperature gas. The converter 5 is used for heat recovery. The paper size is applicable to the Chinese national standard (Οβ) A4 specification (210X297 public) 1293644 A7 _____B7_ V. Invention description ( ) 10 'The movement of coke is indicated by thick arrow, the movement of gas It is indicated by a thin line arrow. (Please read the precautions on the back and fill out this page.) 1) Explain the invention for handling raw materials. Fig. 1 shows the raw material input example-1. Since the coke input is intermittently input at intervals of several minutes to several ten minutes, the raw material is fed between the coke input and the input which are easy to measure the timing of the input. The so-called coke input and investment is the time when the lower part of the dump truck is opened when the coke is put into operation, from the time when there is no coke in the car to the time when the next batch of coke is put into operation. The input position of the raw material is the type of the coke input port, and the type of the raw material input port is separately set. The input method may be carried out by using a cutting device such as a feeder or a flat feeder at each input position to drop by its own weight, and blowing it with a part of the circulating gas 4 or nitrogen gas or the air supplied to the air inlet port 7. method. The type of the circulating gas is such that during the gas temperature drop, the gas after the circulation of the blower is divided into a part and the pipe is laid to the raw material input port 10, and used in combination with a cutting device such as a flat feeder. In the state of nitrogen, the nitrogen is introduced to the raw material input port by the external pipe, and is similarly used in combination with the cutting device. Since the superiority of the airflow transportation can increase the dispersion range by a small number of input ports, The thickness of the layer thickness can be increased by the type of falling from the weight of the crucible: (the situation with the coke input described later is an increase in the dispersibility). Further, the disadvantages of using nitrogen can be minimized by using the circulating gas 4' in the carrier gas. Regarding the input of the coke input and input, the loading between the warehouse and the warehouse is only suitable for the standard of the paper.

Inventive Note () ----- 2 During the CDQ, keep the amount below the thickness of about 15〇mm as the heat transfer condition of all coke reactions (in the CDQ The existence of the shape, and = to: the heat of hot red coke up and down). In the case of the input, the thickness of the power generation heat exchanger 5 in the subsequent stage is limited to the allowable range (the allowable limit of the heat exchange efficiency reduction) of the power generation heat exchanger 5 in the subsequent stage. . It is only in the _L limit system; the reaction enamel is also mixed with the condition that coke is not discharged by CDQ'. That is, under the condition of the dryness of CDQ raw material, the thickness of the carbonized layer and the heat transfer condition, the coke can be put into coke. The amount is about 40% (10) according to the water content, and it is only necessary to set an appropriate input amount based on this relationship. There is no lower limit on the amount of input. In the case of the input from the raw material input port 11, it is preferable to have two or more input ports in order to reduce the unreacted mass and to deposit the layered as much as possible in the front furnace chamber. Usually set about 4 to 16 or so. The coke layer 12 is dropped into the CDQ in a sandwich shape in parallel with the input bio-derived layer 13, and is sequentially discharged from the lower portion. The raw material input into the pre-furnace chamber 2 covers a portion of the coke layer, or preferentially reacts with the input air, reduces the chance of contact between the air and the coke from the air injection port 7, and reduces the amount of coke injected into the air. . When the generated carbon dioxide or water vapor passes through the coke layer 12, it causes the same reaction as in the past and produces carbon monoxide or hydrogen. Fig. 2 shows the raw material input example-2. The difference from the input example _1 is that the coke is input at the same time, and the type of the input place and the input method is the same as that of the input example-1. The so-called "simultaneous input" means that the Chinese National Standard (CNS) A4 specification (210X297 mm) is applied to a certain batch of coke.

The amount of gas input from the biomass is small, and there is no problem at all for the operation. 2) Hereinafter, the present invention for treating the raw material will be described. (1) Input treatment pattern 1 Fig. 4 shows the other of the biomass In the coke dry quenching apparatus, after the furnace cover 17a is opened, the red hot cokes 5 are put into the pre-furnace chamber 18 by the coke input port 17 at the upper portion of the cooling tower 16, and are cooled. The cooling gas gas supplied from the cooling gas pipe 28 at the lower portion of the tower 16 exchanges heat with the red hot coke 15, and the hot high temperature inert gas for recovering the red hot coke U is introduced into the boiler 27 through the flue 24 through the annular duct 19 for heat. After the exchange, the circulating blower 29 is pumped to the lower portion of the cooling tower μ to circulate it. The cooled coke is discharged from the lowermost portion of the cooling tower; the outlet 20 is discharged. ",, the F-furnace furnace chamber 18 is provided with a raw Quality entrance 21 The combustion air is introduced into the mold 22. In the raw material, the wood is coarsely crushed into a size of about 10 to 15 mm by a hammer crusher or the like (not shown), and is continuously charged from the raw material inlet 21. The air inlet 23 for the combustion, the dust collector 26 for collecting the dust separated by the crushing wall 25, and the pipe between the 27 and the circulating blower 29 are provided with a separator 30. In the coke dry quenching unit, the raw material system is treated as follows. The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210^^PCT). The inertia 15 is used for the furnace dust (please read the precautions on the back). On this page), -18- 1293644 A7 B7 V. Inventive Note (16 (Please read the note on the back and fill in this page). The raw system installed in the pre-furnace chamber 18 by the raw material loading port 21 is red hot. The sensible heat of the coke 15 is thermally decomposed into a combustible gas and a biomass fixed carbon. The combustion air generated in the thermal decomposition is continuously combusted in the pre-furnace chamber 18 by the combustion air continuously introduced through the combustion air introduction port 22. The combustion air is used to introduce the amount of air required for complete combustion of the contained biomass (hereinafter referred to as the required amount of air). The biomass-fixed carbon produced by thermal decomposition is similarly burned with combustion air. Since the strength of the biomass-fixed carbon is significantly lower than that of coke, it is pulverized in a packed bed of red hot carrageen 15 . The pulverized biomass-fixed carbon has a surface area which is significantly larger than that of the red hot coke 15 and is preferred because it is thermally decomposed into a porous medium. The result is a preferential combustion of the burning red hot coke 15. Further, since the residence time in the pre-furnace chamber 18 is particularly long compared to the residence time in the flue 24 and passes through the packed bed of the red hot coke 15, the gas is disturbed, so that it can be surely mixed and efficiently The ground is burning. The exhaust gas after the end of combustion contains a small amount of flammable components through its moisture balance reaction, and is introduced into the flue 24 through the annular duct 19. In the flue 24, the combustion air is continuously introduced again by the combustion air introduction port 23. Since the combustible component is small, it is completely burned even in a short residence time, and completely burns between the exhaust gas reaching the pulverizing wall 25 disposed in the flue 24, without unburned biomass-fixed carbon being pulverized. The wall 25 is comminuted. As described above, the fixed carbon in the raw material is completely burned and converted into waste sensible heat, and the steel furnace 27 is efficiently heat-exchanged and heat-recovered. Thereby, a large amount of biomass can be processed in the coke dry quenching device, and the heat is carried out as heat recovery and is effectively utilized as a heat carrying -19-1293644 A7 ____ B7_5. CPlease read the note on the back first and then fill the nest page. Among them, the combustion air for the combustion of the activated carbon and the combustible gas after the combustion of the thermal decomposition is introduced into the flue 24 as described above. In addition, it can be introduced into the annular duct 19 or both. Further, if the furnace cover 17a is opened during the charging of the red hot coke, a large amount of air is introduced from the coke charging inlet 17 at the top of the cooling tower 16. Therefore, there is a risk of an explosion when the current furnace chamber 18 is filled with a combustible gas. Further, since 80% or more of the biomass is a volatile component, a large amount of gas is released. When the total amount of released gas and the amount of air flowing in from the coke charging port 17 exceeds the allowable amount of the circulating blower 29, the top of the cooling tower 16 becomes a positive pressure and the gas is leaked from the coke charging port 17. Therefore, when the raw material is properly treated, the loading of the raw material into the furnace chamber 18 or the reduction of the loading amount is stopped between the opening of the furnace cover 17a of the coke charging inlet 17. Thereby, the capacity of the circulation blower 29 is not enhanced, and leakage of gas or the like can be avoided. (2) Input treatment pattern 2 Fig. 5 shows another input pattern of the present invention. In the pre-furnace chamber 18 of the coke dry quenching apparatus shown in Fig. 5, in addition to the coke charging port 21 and the combustion air introducing port 22, water and/or steam inlet port 31 is provided as described above. When the raw material is burned and used in a large amount in the pre-furnace chamber 18, a temperature rise occurs in the pre-furnace chamber 18. This temperature rise will have an effect on the machine, and it will cause serious problems such as the melting of dust. In general, the melting point of the ash contained in the biomass is lower than the melting point of the coal ash. This paper scale applies to China National Standard (CNS) A4 specification (210X297 mm) -20- 1293644 A7 ---- B7_ V. Invention description ( ) 18 Therefore, when the authorities burn, the dust will scatter in the semi-melting state and adhere. (Please read the precautions on the back and fill out this page) Walls, heat transfer officials, etc. and cause harm. Therefore, combustion temperature management must be performed. Therefore, the temperature control of the form in which the raw material is burned in the furnace chamber 18 is controlled by the temperature at which the inlet port 31 is required to inject water and/or steam. The injected water and/or steam generates a stone disintegration reaction with the water coal rolling reaction (endothermic reaction) in the pre-furnace chamber 18, and cools the pre-furnace chamber 18. With this temperature control, no dust is generated and no unburned gas is generated. The recyclable heat is not discharged as dust, and the biomass can be used to the maximum extent. (3) Input treatment pattern 3 Fig. 6 shows another input pattern of the present invention. In the coke dry quenching apparatus shown in Fig. 6, the combustion chamber air introduction port 32 for introducing the combustion air of the combustion-fixed carbon and the combustible gas after combustion combustion is not disposed in the pre-chamber 18; It is provided in the annular duct 19 and the flue 24. When the biomass-fixed carbon generated by the thermal decomposition of the biomass is burned, since the residence time for introducing the combustion air into the flue 24 is too short, it is difficult to completely burn as described above. Therefore, in the present embodiment, it is configured to introduce combustion air into the annular duct 19, and to lengthen the time for burning the biomass-fixed carbon by the combustion air. In view of its meaning, it is preferable to introduce the entire amount of the necessary air amount from the annular duct 19, but when a large amount of combustion air is introduced into the annular duct 19, the temperature of the combustion heat loop conduit 19 rises remarkably. Further, as the temperature of the annular duct 19 rises, the melting and adhesion of the ash are generated as described above. This paper scale is applicable to China National Standard (CNS) A4 specification (210X297 mm) -21 - 1293644 V. Invention description A7 B7 19 Also, in general, since the inner wall of the annular duct 19 is a brick single structure, there is no high temperature. The strength is such that local high temperatures must be avoided and the inner wall temperature of the annular duct 19 must be maintained below the allowable temperature. Therefore, in the present embodiment, the temperature of the gas in the annular duct 19 is measured by a temperature sensor (not shown), and the amount of combustion air from the annular duct 19 is controlled so that the gas temperature does not rise. The allowable temperature (e.g., 1 〇〇〇 ° C) is exceeded, and the residual amount of the necessary amount of air is injected into the flue 24 . By injecting the combustion air, it is possible to prevent the coke burning in a small amount when the air is introduced into the pre-furnace chamber 18, and the coke loss as a product is not generated, the dust is not melted, and no The gas body will not use the recoverable heat as dust out of the system, and the raw material can be used to the maximum extent. (4) Input treatment pattern 4 Fig. 7 shows another input pattern of the present invention. When the amount of biomass is gradually increased, the heat efficiency of reading is lowered, and the temperature of the raw material is not increased. Therefore, thermal decomposition and combustion cannot be surely performed, and a portion in which thermal efficiency is lowered is generated. Moreover, part (4) is low temperature, and this portion exists in the vicinity of the inner wall of the cooling tower 16, and may also have a bad influence on the brick constituting the inner wall. One of the main reasons for the decrease in heat transfer efficiency is the filling thickness of the raw material. That is, when there is a local thick portion in the filling thickness, the temperature of the effect of the borrowing of the biomass is lowered. The thermal efficiency of the portion is also lowered. Therefore, in order to reduce the thermal efficiency of the ancient umbrella and return the raw material, it is necessary to load the raw material equally into the front furnace chamber to the m to 18.

Further, as shown in Fig. 9, the chute 34 of the raw material loading inlet which can change the inclination angle and/or the direction can be provided in the vicinity of the raw material loading port 21, and the raw material can be more uniformly placed in the front side. Inside the furnace chamber 18. In the above-described input treatment aspect of the present invention, since the combustion air for burning the biomass-fixed carbon and the combustible gas after the thermal decomposition is injected into the pre-furnace chamber, most of the unburned gas is burned in the pre-furnace chamber. . Therefore, the corrosion failure of the equipment is not caused by the residual of the combustible gas, and the biomass can be utilized in a large amount. Further, since the biomass-fixed carbon is preferentially burned in the pre-furnace chamber by the combustion air, the fixed carbon to be charged is not recovered as dust and can be recovered as heat and used effectively. Further, by injecting combustion air into the annular duct and/or the flue, the biomass-fixed carbon can be completely burned, and the heat carried by the biomass can be completely recovered as heat and used effectively. Furthermore, by injecting water and/or steam for temperature control into the pre-furnace chamber, it is possible to control the temperature rise in the pre-furnace chamber without causing the adhesion of the ash in the raw material having a lower melting point, It can handle a large amount of raw materials, and can use all the heat carried by the raw materials as heat recovery and effective use.

The heat is all recovered as heat and used effectively. When the combustion air is injected into the annular duct, the amount of combustion air to the annular duct is controlled so that the temperature of the loop duct does not exceed the allowable temperature, and the residual amount of the necessary air is blown by the flue, thereby preventing The combustion of coke produced in a small amount in the pre-furnace chamber does not cause the loss of coke of the product, and does not cause the adhesion of the ash in the raw material having a lower melting point, and the raw material can be processed in a large amount. And the heat carried by the biomass is all taken as heat recovery and effectively utilized. Further, the raw material loading into the furnace chamber is carried out by two or more inlets or the cutting and dispersing device having the rotating blades is provided in the vicinity of the raw material charging inlet, or can be changed in the vicinity of the raw material loading port. The sliding groove for the inclination angle and/or the direction of the raw material can be used to disperse the raw material in the pre-furnace chamber and uniformly load it to prevent the temperature from falling due to the heat-dissipating effect of the biomass, and the temperature is not generated. The adverse effects of the change on the refractory will not cause thermal degradation due to thermal decomposition of the biomass or insufficient combustion, but can handle a large amount of biomass, and all the heat carried by the biomass is used as heat recovery and effective use. Further, when the lid of the red hot coke is opened, the loading of the biomass to the pre-furnace chamber can be stopped or the amount of the filling can be reduced to avoid gas leakage.
