In another technical solution, coke oven is additionally provided with the pipeline between coal gas processing device and Coke-oven Gas Boiler Gas chamber 3, the gas exit of coke-oven coal gas holder 3 by pipeline respectively with the gas inlet of Coke-oven Gas Boiler 4 and coke oven 1 plus Heating gas inlet communication.Coke-oven coal gas holder can be cached coal gas, weaken gas yield and composition fluctuation to subsequent user Adverse effect, the coal gas part cached in coke-oven coal gas holder 3, which is admitted in Coke-oven Gas Boiler 4, is used as coke-oven coal steam pot The main fuel of stove 4, another part are admitted to the heating fuel as coke oven 1 in coke oven 1, can so realize coke oven by-product gas Full utilization on the spot.
In another technical solution, in addition to flue gas heater 15, the air inlet and desulfurizer of flue gas heater 15 10 connections, the gas outlet of flue gas heater 15 connects with chimney 11.Because the flue-gas temperature after desulfurization process is about 90- 110 DEG C, and the hot standby temperature of the requirement of fume emission chimney 11 is generally 130 DEG C, therefore on the exhaust pass of desulfurizer 10 Flue gas heater 15 is set, the flue gas after desulfurization is sent to chimney 11 to 130 DEG C or so again, finally by the row of chimney 11 to Air.
In another technical solution, low-temperature zone economizer 80, the heating of closed cycle water are provided with waste heat reclaiming flue 8 Device 81 and air preheater 82;
The water inlet of low-temperature zone economizer 80 is connected with the feedwater interface of external boiler, the delivery port of low-temperature zone economizer 80 It is connected with the water inlet of the high-temperature flue high temperature section economizer 12 of Coke-oven Gas Boiler 4;
Connect to form closed cycle by pipeline between closed cycle water heater 81 and flue gas heater 15, closed cycle The recirculated water import and export of water heater 81 goes out with the recirculated water of flue gas heater 15 respectively, import is connected, the closed cycle of formation Water circulating pump 16 is additionally provided with pipeline, to overcome the resistance on closed cycle pipeline;
The air outlet of air preheater 82 is connected with the burner of Coke-oven Gas Boiler 4.
In the above-mentioned technical solutions, low-temperature zone economizer 80 is used to preheat the boiler feedwater after deoxygenation, The high temperature section that feedwater in low-temperature zone economizer 80 after preheating is sent in the back-end ductwork of Coke-oven Gas Boiler 4 saves Coal device 12;Pass through pipe between the flue gas heater 15 set on the exhaust pass of closed cycle water heater 81 and desulfurizer 10 Road connects to form closed cycle, the recirculated water import and export circulation with flue gas heater 15 respectively of closed cycle water heater 81 Water goes out, import is connected, and the heat in waste heat reclaiming flue 8 is transferred in flue gas heater 15, to heat the flue gas after desulfurization; The setting of water circulating pump 16 can overcome the resistance on closed cycle pipeline;Air preheater 82 is then used to cold air being preheated to Coke-oven Gas Boiler designs wind-warm syndrome.This design can carry out depth recovery to the medium temperature fume afterheat after denitrification apparatus 7 Utilize, obvious heat of smoke is used for feed-water preheating, air preheat and the heating of desulfurization after-purification waste gas of Coke-oven Gas Boiler.This The design of waste heat reclaiming flue 8 has taken into full account that flue-gas temperature is high and big (the boiler smoke caused by Coke-oven Gas Boiler of exhaust gas volumn With coke oven caused by coke oven exhaust gas summation) the characteristics of, if according in conventional boiler merely by way of preheated air without The flue-gas temperature of intimate double flow is reduced by 200 DEG C or so by method, thus the present invention set in waste heat reclaiming flue three-level by Hot face, that is, boiler feedwater preheating, air preheat and the heating of flue gas after desulfurization is set to absorb smoke heat energy, it is not only efficiently sharp With fume afterheat, flue-gas temperature is caused to be reduced to desulphurization system requirement condition so as to meet desulfurization requirement again;In addition, it is all by The setting in hot face is based on from the second law of thermodynamics, and the step that smoke heat energy is realized by the level-density parameter of heat-exchange system is high Effect utilizes.
In another technical solution, valve is provided with coke oven exhaust gas flue 1 and coke oven exhaust gas flue 26, just Valve in the case of often on coke oven exhaust gas flue 1 is closed, the valve opening on coke oven exhaust gas flue 26, and coke oven comes out useless Gas enters in the high-temperature flue of Coke-oven Gas Boiler 4 from coke oven exhaust gas flue 26;When there are abnormal conditions in system, coke oven exhaust gas Valve on flue 26 is closed, and the valve opening on coke oven exhaust gas flue 1, coke oven exhaust gas does not enter back into Coke-oven Gas Boiler 4 High-temperature flue and without denitration and desulfurization process, but directly discharged from chimney 11.Also set up on coke oven exhaust gas flue 26 There is deduster 14, to carry out dust removal process to the coke oven exhaust gas in coke oven exhaust gas flue 26, prevent from influenceing the effect of lower procedure Fruit.
Described in an illustrative manner above with reference to accompanying drawing according to coke-oven plant's coke-stove gas of the present utility model utilization and flue gas Processing system.It will be understood by those skilled in the art, however, that the coke-oven plant's coke-stove gas proposed for above-mentioned the utility model Using with smoke processing system, various improvement can also be made on the basis of the utility model content is not departed from.Therefore, this reality It should be determined with new protection domain by the content of appended claims.
