Description
Technical field
The utility model is related to technical field of energy saving and environmental protection, more particularly to a kind of coke dry quenching furnace flue gas desulphurization unit.
Background technology
Quenching refers to that the high-temperature coke that will have been refined is cooled to the temperature for being readily transported and storing.The mode of quenching has in stove
Outer two kinds of the quenching of quenching and stove, and to be the outer quenching of stove can be divided into Dry Quenching for quenching outside stove using wide at present
With two class of wet quenching.
Wherein, Dry Quenching process is specially：The high-temperature coke released from coke oven is packed into dry by furnace roof charging apparatus
Put out stove.Cryogenic inert gas is sent by the feeder at coke dry quenching furnace bottom in coke dry quenching furnace by circulating fan, in coke dry quenching furnace, high temperature
Coke carries out heat exchange with the cryogenic inert in gas-circulating system, and high-temperature coke is cooled to form coke after cooling, low temperature
Inert gas is thermally formed high temperature inert gas.Coke after cooling drains into conveying device through discharging device for coke, is then sent to
The burnt system of sieve.The high temperature inert gas for being entrained with a large amount of coke powders is settled through disposable dust remover, and dry coke quenching pot is entered after sedimentation
Stove exchanges heat.In coke dry quenching boiler, high temperature inert gas temperature is cooled, forms cryogenic inert gas.Cryogenic inert gas by
Coke dry quenching boiler comes out, and after secondary filter, then is sent into coke dry quenching furnace by circulating fan and recycles.
However, in actual production, sulphur would generally be remained from the high-temperature coke that coke oven is released, also, due to gas
Circulatory system negative pressure section can leak into air, and remaining sulphur can react with air and generate SO in high-temperature coke2, lazy to low temperature
When property gas is diffused, the SO of generation2It can be emitted into air, pollute the environment with cryogenic inert gas.Through surveying
It is fixed, diffuse the SO being discharged when cryogenic inert gas2Content has been far longer than《Coking chemistry emission of industrial pollutants standard》
(GB16171-2012) SO in being generated when Dry Quenching2The regulation of discharge capacity.
Therefore, it is necessary to the SO in recyclegas2It is handled, to reduce the pollution to environment.In a kind of feasible side
In case, the recyclegas diffused can be delivered in the desulfurizer of coke oven and carry out desulfurization process, however, due to recyclegas
Middle SO2Content be far smaller than the SO generated in coke oven2Content, therefore, if using the desulfurizer of coke oven to recyclegas
In SO2Desulfurization is carried out, SO in the desulphurizing ability and recyclegas of the desulfurizer of coke oven can be caused2The mismatch of content, is caused
The wasting of resources.
