Background technology
Coke is one of requisite secondary energy raw material of China's important material for industrial production, particularly metallurgical industry.The present coke turnout of China is at the forefront in the world according to statistics.In industrial process of coking, after red Jiao released from coke oven, one will make coke extinguish, and prevented that it from continuing oxidizing fire in atmosphere; Two will lower the temperature rapidly, so that the coke moulding; Three will wash its surperficial powder, to guarantee the coke quality, guarantee that simultaneously the moisture content of coke is qualified.At present coal chemical enterprise adopts the wet quenching technology more, so will be with a large amount of cool water shower quenchings.Simultaneously, for water saving, adopt the quenching of recirculated water spray more.
Existing coke quenching device is made up of following part usually:
1) coke quenching tower up to tens of meters, its top leads directly to atmosphere, and lower open is covered with track, for the quenching car turnover;
2) waterworks;
3) quenching car;
4) circulating water pool;
5) water pump and controlling organization etc.
Its working process is: when vehement red coke pushes quenching car from stove after, promptly promote to enter into the bottom of coke quenching tower by locomotive along track, waterworks moment is to a large amount of water of red burnt ejection, so that coke extinguishes rapidly.But during up to the vehement red coke of more than 1,000 degree, instantaneous heat absorption vaporization produces hot rising steam air mass in a large number to water in the contact temperature.Consequent a large amount of steam does not reclaim, and emptying in vain causes the waste of water resources and the pollution of environment.According to statistics, at present one ton of coke of the every production of enterprise is generally wanted about 0.5 ton of consume water, all with vapor form through the coke quenching tower emptying, though wherein the coke quenching water of spray back remainder is got back to circulating water pool through the waterways, can use again, yet the contained moisture of the steam of emptying but can't reclaim.
Pay attention to water saving, energy-conservation today in the whole society, how to reclaim the steam of these dischargings, save great amount of water resources, protect environment, extremely urgent important topic really.
The utility model content
The technical problems to be solved in the utility model is: a kind of coke quenching tower vapor-recovery unit is provided, to reclaim the steam that produces in the quenching process, avoids the huge waste of water resources.
Technical solution of the present utility model is: a kind of coke quenching tower vapor-recovery unit, described coke quenching tower comprises water spray quenching section and emptying flue, described water spray quenching section is provided with the quenching waterworks, described water spray quenching section bottom forms airtight relatively space, described coke quenching tower vapor-recovery unit comprises the water spray quenching section that is arranged at this coke quenching tower and the cooling and absorbing device between the emptying flue, constitutes cooling down absorption segment in this coke quenching tower.
Characteristics of the present utility model and advantage are: in the quenching operation of industrial coking, coke quenching water and the instantaneous high-temperature steam gas that produces that contacts of vehement red coke, steam is in uphill process, after coke quenching tower vapor-recovery unit processing of the present utility model, because the waterworks of staggered arrangement, make tortuous rising of vapour stream spray through coke quenching water, behind the abundant heat-shift of water coolant, temperature reduces, the a large amount of condensed water that obtain after the condensation can be reclaimed through gravity separation, and then utilize again, the breeze dust of contaminate environment also is separated, and other insoluble gas is then through the discharging of coke quenching tower top emptying flue, thus, avoided the waste of water resources, and reduced pollution environment.
