High-effective dust-removing coke quenching tower

Abstract

The invention relates to a highly effective dust removal coke quenching machine, which includes a coke quenching injection pipe, a washing and cooling device, and a dust removal device. The dust removal device, which is disposed single-stage or two-stage, includes a structural framework, a dust removal plate, a dust removal pipe and nozzles, wherein the dust removal plate, which is constituted of a heterotypic baffle sheet folded with a certain angle and a dust removal plate support, is disposed on the structural framework and forms angle of 45-60 DEG with horizontal plane; the dust removal pipe is equably equipped with a plurality of nozzles and is arranged parallel with the dust removal plate. Dust content of stream generated at coke quenching process is greatly reduced by water fog washing, cooling, gravitational settling and purifying of baffle plate type dust removal device, amount of coking powder discharged into air of per ton coke is lower than 50g. Moreover, the baffle plate employs industrial plastic, thereby possessing advantages of corrosion resistance, high strength, aging resistance, good dust removal effect, convenient installation and maintance, and easy cleaning.

Description

technical field [0001] The invention relates to a special equipment for extinguishing red-hot coke with water, in particular to a high-efficiency dust removal and coke quenching tower. Background technique [0002] In the coking gas plant, the final temperature of coal carbonization into coke in the coke oven carbonization chamber is 950-1050°C, so the hot coke pushed out from the carbonization chamber is suitable for transportation and storage, prolongs the life of conveying equipment, and reduces It must be extinguished so that its temperature drops below 200°C. At present, the coke quenching method commonly used in domestic coking and gas production plants is the wet coke quenching process. Wet coke quenching is to introduce the hot coke from the carbonization chamber into the coke quenching car through the coke arrester, and then pull it to the coke quenching tower via an electric locomotive for spraying water to quench the coke.

AI Technical Summary

Problems solved by technology

Normally, about 1,000g of coke powder per ton of coke will be taken away by the quenching steam during the coke quenching process. The traditional wet coke quenching tower only uses a single-layer baffle type dust removal device in terms of dust removal measures. 120-150g of coke powder is taken away by the quenching steam and discharged into the atmosphere, which has a serious impact on the surrounding environment
