Description

The semi coke furnace dry quenching device

Technical field

The utility model belongs to coking industry, relates to a kind of semi coke furnace dry quenching device, is a kind of to the supporting dry coke quenching auxiliary of blue charcoal stove.

Technical background

In China, the quenching mode of the blue charcoal stove of blue charcoal processing enterprise all is wet quenching, has not only caused the significant wastage of the energy, and has seriously polluted environment.

The coke quenching device that present blue charcoal production is adopted is long 9 meters, wide 2.8 meters, high 1 meter hydrolock quenching groove, a supporting cover oven dry bed, quenching, oven dry, coke discharging.Scorching hot blue charcoal about about 550 ℃ in the burner hearth extinguishes and cool off and deliver to coke bin after dry by scraper conveyor drying bed the back in pushing machine pushes the quenching groove that fills with coke quenching water, transports behind the crushing and screening.

The problem that existing coke quenching device exists is;

1) quenching process is the direct quenching of water, consume a large amount of moisture, puts out one ton of blue charcoal and will consume about 0.2 ton of coke quenching water through measuring and calculating is whenever wet;

2) a large amount of steam of coke wet quenching generation directly enter atmosphere, and red Jiao's sensible heat is also along with the discharging of steam is wasted.The heat of 1 ton of blue charcoal consumption of every refining is about 2.21～2.35GJ, and wherein the heat of coke wet quenching waste is 1.05GJ, accounts for 45% of wastage in bulk or weight heat;

3) the blue charcoal of releasing from coking chamber, temperature is about 550 ℃, red blue charcoal sharply cooling in water during coke wet quenching, blue charcoal internal structure produces very big thermal stresses, and map cracking is more, and void content is very high, so its barrate strength is lower, and the fragile fritter that is cleaved into;

4) red blue charcoal cools off in water during coke wet quenching, and cooled wet blue charcoal needs heating, drying, has wasted a large amount of coal gas;

5) in the coke wet quenching process, red blue charcoal contacts with water and produces a large amount of objectionable impuritiess such as phenol, cyanogen compound and sulphur compound, and the steam that produces with quenching freely discharges heavy corrosion surrounding devices and atmosphere pollution.
