The dryer 130 is rotated by the drive unit 132a and is horizontal to stir the bio fillets introduced on the supply conveyor 132b. It consists of a stirring drum 132 and a drying chamber 134 installed at the end of the horizontal stirring drum 132 and in which a discharge hopper 134a for discharging dried bio fillets is installed. Here, the horizontal stirring drum 132 has a screw blade installed on the inner circumferential surface or installed at a predetermined inclination angle, so that when the horizontal stirring drum 132 rotates, the bio fillet rides on the inner bottom of the horizontal stirring drum 132 to the inlet end 132c It passes through the outlet end (132d) and gathers toward the discharge hopper.

In addition, the supply conveyor 132b is connected to the molding machine 120 by a belt conveyor or a screw conveyor to supply bio fillets in a fixed amount. At this time, the supply conveyor 132b is controlled by the control unit to maintain the internal capacity of the stirring drum 132 at a height higher than that of the lower end of the multi-supply pipe 440 described later and lower than that of the main supply pipe 420 by the control unit. It can be configured to be adjustable. The control unit detects the internal humidity of the stirring drum 132 by means of a sensor and dynamically adjusts the drying throughput of the bio fillet according to the rotational speed of the stirring drum 132 and the speed of the supply conveyor 132b.

In addition, a waste heat circulation unit 400 connected to the drying chamber 134 and inputting and exhausting exhaust gas into the stirring drum 132 is provided. Here, the waste heat circulation unit 400 injects the exhaust gas that has passed through the bag filter dust collector 340 described later into the dryer 130 to dry the bio fillet, and recovers the exhaust gas discharged together with moisture during the drying process. .

To this end, as shown in FIG. 2, the waste heat circulation unit 400 is installed in the longitudinal direction inside the horizontal stirring drum 132 and is connected to the main supply pipe 420 through which the exhaust gas is moved and the main supply pipe 420 A plurality of multi-supply pipes 440 extending downward so that the lower end is buried into the bio fillet accommodated in the horizontal agitating drum 132 to inject exhaust gas, and a gas outlet for discharging exhaust gas recovered into the drying chamber 134 ( 460).

That is, the exhaust gas supplied in the longitudinal direction of the stirring drum 132 through the main supply pipe 420 is distributed and supplied through the multi-supply pipe 440, and at this time, the end of the multi-supply pipe 440 through which the exhaust gas is sprayed is a conveyor ( 132b) to be placed in a state of being buried in the fillet supplied.

Therefore, while the bio fillets are stirred along the inner circumferential surface of the stirring drum 132 in the circumferential direction, dried high-temperature heat is supplied to the fillets located at the bottom of the stirring drum 132 by the exhaust gas sprayed through the multi-supply pipe 440. In this case, the exhaust gas drying the fillet is discharged through the upper gas outlet 460 of the waste heat circulation unit 400.

Accordingly, the exhaust gas (hot air) supplied to the main supply pipe 420 is sprayed to the inclined surface 410 through the injection nozzle 412, so that the bio fillets stacked on the upper part of the main supply pipe 420 are scattered by the hot air, and the inclined surface A phenomenon in which the bio fillet is stuck in a stacked state on the upper part of the main supply pipe 420 by being moved downward along the 410 is prevented.

The dryer 130 of the present invention is uniformly and stably dried by the exhaust gas supplied from the multi-stage multi-supply pipe 440 in the process of transporting the bio fillets to the drying chamber 134 and the stirring structure in the circumferential direction. Efficiency is improved.

The power generation unit 200 according to the present invention consists of an incinerator 210 that burns the biomass that has passed through the preprocessing unit 100, and a generator 230 that generates electricity by turning a turbine 220 as a heat source of the incinerator 210. . That is, steam is generated using the heat source of the incinerator 210, and the turbine 220 is turned to drive the generator 230 using the steam.

Figure 3 is a configuration diagram showing an enlarged view of the incinerator of the biomass power generation system of the present invention, Figure 4 is a configuration diagram showing the operating state of the incinerator.

The incinerator 210 has a main combustion chamber 212 in which a biomass supply unit 212a, a grate 212b, and a main burner 212c are installed, and an inclined circulating wall 212d having a diameter reduced toward the top is formed. And, a multi-combustion chamber 214 extending to the upper part of the main combustion chamber 212 and having a multi-burner 214a installed therein, and supplying FGR air mixed with exhaust gas to the lower part of the grate 212b. 1 air supply unit 216, a second air supply unit 217 installed above the multi-burner 214a and injecting air, that is, over fire air (OFA), in a lateral direction inside the multi-combustion chamber 214, a multi-burner 214a It is installed at the bottom and consists of a third air supply unit 218 for injecting FGR air mixed with exhaust gas in the horizontal direction inside the multi-combustion chamber 214. At this time, at least one of the main burner 212c and the multi-burner 214a uses palm acid oil obtained by refining palm oil factory wastewater, which is the largest waste by-product generated in the crude oil palm oil production process, as an auxiliary fuel. By using it, it is possible to have an eco-friendly system.

In addition, since the FGR air is supplied to the lower part of the grate 212b by the first air supply unit 216 to control the temperature of the grate and the internal temperature of the incinerator 210, clinkering is prevented.

Referring to FIGS. 3 and 4, the grate 212b is installed at an inclined angle in the main combustion chamber 212, and a biomass supply unit 212a for supplying dried bio fillets is installed on the high side, corresponding to the low side of the main combustion chamber. A burner 212c is installed, and an air curtain is formed between the main combustion chamber 212 and the multi-combustion chamber 214 by FGR air injected through the third air supply unit 218.

Flames and high-temperature combustion gases generated when bio fillets are burned by the main burner 212c in the main combustion chamber 212 are transferred to the multi-combustion chamber 214 by the air curtain formed by the third air supply unit 218. The exhaust gas (flame) movement is decelerated, and the flame of the main burner 212c is expanded toward the biomass supply unit 212a by the inclined wall 212d, riding the inclined wall 212d on the opposite side. It has a circulation structure that circulates downward.

Accordingly, as the gas containing high-temperature air by the combustion reaction is injected and circulated at high speed in the main combustion chamber 212, the time spent in the air in the main combustion chamber 212 is increased, thereby maximizing the oxidation reaction in the main combustion chamber 212 area. do.

Furthermore, there is an advantage in that generation of harmful gases including rust and carbon monoxide is remarkably reduced due to circulating re-burning of the exhaust gas inside the main combustion chamber 212 as well as temperature control of the main combustion chamber 212 and the grate 212b.

In addition, an air curtain is formed on the upper part of the multi-combustion chamber 214 by air injected through the second air supply unit 217, and the movement of the exhaust gas moving through the multi-combustion chamber 214 is decelerated by the air curtain. It is provided to be re-burned by the multi-burner (214a) flame. That is, by re-burning the exhaust gas exhausted from the main combustion chamber 212, generation of harmful gases including an oxidizing agent and unburnt hydrocarbons (UHC) is remarkably reduced.

The flying object treatment unit 300 according to the present invention includes a submersible collector 320 that separates the coarse fly products included in the exhaust gas of the incinerator 210 with a specific gravity difference, and a fine rain particle included in the exhaust gas from which the coarse fly products are separated. It consists of a bag filter dust collector 340 that separates and collects the product.

The submersible collector 320 of the flying object processing unit 300 induces the lateral movement and downward movement of the exhaust gas exhausted from the incinerator step by step, thereby immersing and collecting the coarse flying objects included in the exhaust gas step by step due to the difference in specific gravity First and second immersion chambers 322 and 324 are provided. That is, the first immersion chamber 322 is connected to the exhaust port of the incinerator 210 in the transverse direction and has a collecting hopper at the lower portion so that the outlet side is at a higher position than the exhaust gas inlet port. As a result, while the exhaust gas moves in the lateral direction along the first immersion chamber 322, the coarse flying objects fall downward and are collected due to the difference in specific gravity.

The second immersion chamber 324 is installed upright, has an exhaust gas inlet at the top, an outlet at the lower side wall, and a collection hopper at the bottom. Accordingly, while the exhaust gas flows backward from the upper part to the lower part of the second immersion chamber 324, the moving speed is reduced, and the coarse fly products are deposited and separated in the collection hopper due to the difference in specific gravity. Meanwhile, it is also possible to install a water pipe in the second immersion chamber 324 to preheat and supply water supplied to the power generation unit 200 for steam generation.

The bag filter dust collector 340 connected to the lower side of the second immersion chamber 324 is provided to separate and collect fine flying objects included in the exhaust gas that has passed through the second immersion chamber 324 . The fine fly products separated through the second immersion chamber 324 are collected and processed in the fly ash silo along the discharge conveyor together with the coarse fly products discharged from the submerged collector 320, and the filtered exhaust gas is bag filter dust collector ( 340) It is discharged to the top and supplied into the dryer 130 through the aforementioned main supply pipe 420.

The dust filtering unit 500 according to the present invention is configured to receive exhaust gas discharged from the waste heat circulation unit 400 by a blower, purify it, and discharge it to the outside. In the dust filtering unit 500, at least one of an activated carbon supplying unit, a powdered lime supplying unit, and a dust collecting agent supplying unit is installed on the exhaust gas inlet side. Further, the dust filtering unit 500 has a plurality of distribution passages formed in the longitudinal direction therein, an exhaust gas inlet on the lower side wall and an exhaust gas outlet on the upper side, and a conical collecting hopper is formed on the lower bottom. In addition, since a plurality of the filtering and collecting units 500 are connected and activated individually by a valve, they are provided.

Accordingly, while the exhaust gas is moved to the dust filtering unit 500, at least one of activated carbon, powdered lime, and a dust collecting agent is mixed and agglomerated to increase the size of the fly products, and As the exhaust gas movement is decelerated by the flow of the exhaust gas, the large-sized flying products are deposited and collected through the lower collection hopper due to the difference in specific gravity.
