Description
Technical field：
The invention belongs to waste heat utilization equipment technical field, and in particular to a kind of waste heat of coke-oven flue gas, raw coke oven gas waste heat and dry put out
The method of comprehensive utilization of burnt waste heat.
Background technology：
Coke oven is height (exergy in energy conversion device:Heating power system working medium can use can) Thermal Equipment of efficiency, net efficiency is high
Up to 87%~89%.Process of coking is not only a more perfect conversion process of energy, produces good secondary energy sources.
The energy stream of analysis coke oven production process can be seen that the output terminal in coke oven：
250~300 DEG C of coke oven flue exhaust gas take heat out of and account for the 17% of the total heat outputting of coke oven, and currently employed waste heat boiler can return
Receive heat production low-pressure saturated steam；
650~700 DEG C of coal gas and gaseous state chemical products are discharged with thermal energy and chemical energy from tedge, and raw coke oven gas is taken heat out of and accounted for
The 36% of the total heat outputting of coke oven, capacity coke oven coking heat consumption is burnt for 108kgce/t, then produces the raw coke oven gas that coke per ton produces
Equivalent to 38.9kgce heats are taken out of, the current developing trend of tedge heat recovery technology is multi-sourcing, but isolated operation has throwing
Capital amount is high, and effective utilization rate of energy is low, excessively recycling thermal energy easily causes the drawbacks such as tedge product tar；
950~1050 DEG C of red Jiao is pushed out from carbonization chamber, its sensible heat taken out of accounts for the 37% of the total heat outputting of coke oven, currently adopts
Its 80% sensible heat can be recycled with ripe Dry Quenching Technology.
Data above can be seen that since temperature gradient difference will recycle the steam resource of different energy level qualities, in big-and-middle formed coke
Change integrated complex, residual-heat utilization technology is gradually improved, and low-pressure steam is often crossed and contained, as can effectively can by coking low-lying level with reason
Utilized with energy level can be improved, great economic benefit will be produced, at this stage still without technological break-through in this respect.
The content of the invention：
The purpose of the present invention is realize to utilize dry coke quenching waste heat, coal oven dithio-gas sensible heat and waste heat of coke-oven flue gas synthesis production high
Warm high steam.The water supply of tedge waste heat is produced as using low-quality flue gas waste heat and produces superheated water, as the cold of raw coke oven gas
But medium, absorbs crude-gas sensible heat, produces the superheated steam of middle high-quality, and superheated steam is sent into dry coke quenching residual heat boiler, inhales
Receive dry coke quenching recyclegas high-temperature residual heat, the row such as the high-quality high-temperature high-pressure overheat steam of generation is used to generating electricity, chemical industry, steel
Industry.
The technical solution adopted by the present invention is：A kind of synthesis of waste heat of coke-oven flue gas, raw coke oven gas waste heat and dry coke quenching waste heat
Application way, comprises the following steps：
Step 1：Filling red burnt coke tank truck will carry burnt by locomotive haulage to traversing draw-gear, traversing draw-gear
The transverse-moving trolley of tank draws to lift headframe bottom, elevator from carrier loader and lifts burnt tank and send to coke dry quenching furnace furnace roof, leads to
The charging apparatus with distributing device is crossed to load coke in coke dry quenching furnace；Coke directly carries out hot friendship with inert gas in coke dry quenching furnace
Change, coke is cooled to less than 200 DEG C, is discharged to through discharging device for coke on ribbon conveyer, is sent to burnt processing system；Circulated air
Machine blasts the feeder of the inert gas from the coke dry quenching furnace bottom that cool down coke in coke dry quenching furnace, with red heat coke countercurrent flow；
The circulating hot gases temperature discharged after disposable dust remover dedusting is about 880~960 DEG C, is exchanged heat into dry coke quenching residual heat boiler,
Temperature is down to 160~180 DEG C；The SAPMAC method gas come out by boiler is pressurizeed after secondary filter dedusting by circulating fan, then
Enter coke dry quenching furnace after feed water heater is cooled to about 130 DEG C to recycle；
Step 2：Generate electricity condensed water（Demineralized water）After feed-water preheating, oxygen-eliminating device deoxygenation is sent；
Step 3：Another way send waste heat of coke-oven flue gas return device, receives 180 DEG C of overheat steam of production and is returned for ascending tube crude-gas waste heat
Receive；
Step 4：The superheated steam of 350 ± 30 DEG C of temperature is produced after ascending tube crude-gas heat exchange, send coke dry quenching boiler and dry coke quenching
Enter secondary superheater for dry quenching boiler after superheated steam mixing temperature adjustment, product vapour is sent outside after high temperature circulation gas overheat.
Beneficial effects of the present invention：Prior art ton Jiao waste heat of coke-oven flue gas recycles 150-180 DEG C of steam 60-80kg/t；
200-210 DEG C of low-pressure steam 80-100kg/t of raw coke oven gas thermal energy recycling production；The burnt production 8.83MPa of dry coke quenching heat recovery ton, 540
± 5 DEG C of high temperature and high pressure steam 540-560kg/t.Though low-pressure steam can realize classified utilization, general coal chemical enterprise low pressure is steamed
Vapour crosses Sheng, and residual steam is used to generate electricity, and low-pressure steam generates electricity the steam consumption apparently higher than high steam.Using can be real after this patent scheme
Now comprehensive production 10.3MPa, 540 ± 5 DEG C of high temperature and high pressure steam 660-730kg/t, low-pressure steam and the high steam energy by
Price differential calculates, and ton is burnt to be can be achieved to increase profit more than 10 yuan.In addition it this method solve tedge and take the felt jams such as thermal tar
The problem of；All the time there is the flowing of high temperature carbonated drink in tedge.
