Dome type dust removing coke quenching machine

Abstract

The invention relates to a dome-like dedusting coke quenching tower, which comprises the following parts: a coke quenching procedure at the bottom and a deduesting procedure at the top, wherein the coke quenching procedure is equipped with a coke quenching injecting pipe; the dedusting procedure is divided into three lattices; the bottom of two side lattices sealed by a tipping plate; the bottom of the tipping plate is equipped with blow-off hole; the included angle alpha of the tipping plate and the horizontal surface is 10-75 degree; the top of the coke quenching injecting pipe and the middle lattice entrance of the dedusting procedure are equipped with a plurality of washing and cooling devices; the top of washing and cooling devices and the top of the coke quenching tower are equipped with dome-like dedusting device which covers the middle lattice and two side lattices of the coke quenching tower dedusting procedure. The invention reduces the dust content after washing the polluting vapor with the water fog, cooling the polluting vapor, settling the polluting vapor gravitively and changing the direction of the gas flowing, which reduces the water consumption.

Description

technical field [0001] The invention relates to a special equipment for extinguishing red-hot coke with water, in particular to a dome-type 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.

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
