Abstract
The utility model discloses a heat-insulating water seal tank on the top of a dry coke quenching furnace. The heat-insulating water seal tank comprises a water seal tank body, wherein special-shaped refractory bricks are uniformly distributed on the inner wall of the water seal tank body along the circumferential direction; expansion gaps are formed between the special-shaped refractory bricks and water seal tank body; and the special-shaped refractory bricks have segmental structures. According to the heat-insulating water seal tank, the expansion gaps are formed to meet the requirement of different variations between the self-expansion amounts of refractories and the expansion amounts of rolled steel during temperature change, so that the use effects of special-shaped brick structures are ensured; and meanwhile, the special-shaped refractory bricks are provided with segmental structures, so that online replacement of the special-shaped refractory bricks can be realized, the blowing-down time of the dry coke quenching furnace and the time for cooling and repairing the water seal tank are shortened greatly, and rapid recovery of production is guaranteed.
Description
Technical field
The utility model relates to coal chemical technology dry coke quenching Technology field, particularly a kind of dry coke quenching furnace roof insulating water sealing groove.
Background technology
Dry Quenching Technology is as a kind of novel process that can improve coke strenth, save energy, protection of the environment, and new technology domesticly is constructed and put into operation the First dry coke quenching auxiliary so far from 1985, and the development of Dry Quenching Technology reaches its maturity.Dry coke quenching furnace top water seal tank is as very important single devices in the dry coke quenching auxiliary, its main effect is exactly to utilize annular water seal to play sealing, cooling effect, cooperate simultaneously the dried manhole cover of stove charging apparatus and the chute of packing into of putting out, form certain water seal height, make dried high temperature circulation gas and the atmospheric isolation that puts out furnace interior, both prevented that air was from the fire door dried stove that puts out that bleeds, a large amount of dust when preventing from again packing coke into escape, thereby avoid burning out furnace top equipment, pollute the situation generations such as surrounding environment.
The Working environment of dry coke quenching furnace top water seal tank is more abominable, is in for a long time high temperature naked light state, and fire door place, water sealed tank place temperature is along with the frequently switch of bell, rapid heat cycle, and it is also larger to fluctuate.At present, the top water seal tank that generally adopts in the dry coke quenching industry is frequent the appearance because of water sealed tank cracking drainage in its use procedure, cause that water-gas reaction occurs in the dried furnace roof section of putting out, operation has brought serious potential safety hazard to whole system, leak simultaneously and also accelerated the rate of decay of fire door refractory materials, greatly reduce the work-ing life of water sealed tank.No matter be thorough shutdown maintenance, or under the hot situation it overhauled, all later maintenance and actual motion cost, the benefit of dry coke quenching are brought tremendous influence, had a strong impact on the normal organization of production of dry coke quenching.
In actual production process, have the interior Working environment that improves top water seal tank along wall cast amorphous refractory as thermofin at the dry coke quenching water sealed tank in the same industry, thereby the Patents technology that prolongs its work-ing life: as Patents technology (application number: CN200710198429.6, the title: heat-insulation water-sealing groove for coke dry quenching furnace and preparation method thereof of in water sealed tank, pouring into a mould amorphous refractory along wall; Application number: CN200720310344.8, title: heat-insulation water-sealing groove for coke dry quenching furnace), the main contents of this Patents technology comprise: a kind of heat-insulation water-sealing groove for coke dry quenching furnace and preparation method thereof, water sealed tank comprises a base plate, gas via-hole is offered at the base plate center, the periphery of through hole arranges respectively outer skirt and the inner skirt of projection, its feature is base plate, outer skirt at described insulating water sealing groove, the inner skirt components welding is fixing forms, inboard in described inner skirt arranges refractory insulating layer, and thermofin forms for cast.The major defect of this correlation technique is to be subjected to the restriction of the on-the-spot environment for use of water sealed tank, by weld anchor firmware on the water sealed tank inwall, then play the guard method of casting material, its mould material comes off especially easily, the constructions such as the later maintenance of water sealed tank, replacing are all brought inconvenience, and mould material must all thoroughly be removed original mould material after coming off, then just can re-start integrated poured, if just repair the place that comes off, then can destroy the globality of mould material, then affect its follow-up result of use and life-span; In addition, mould material needs curing time to grow (being greater than 48 hours) after coming off and repairing, and can not normally produce by immediate recovery, and this will break the coke oven line balancing; Because meanwhile, owing to be subjected to the requirement of indefinite form refractory castable construction, this technology has just been carried out thermal insulation protection to the Nei Yanbi of water sealed tank, and any protection not being carried out in the bottom surface of water sealed tank also is to affect a top water seal tank factor in work-ing life.
