The invention provides a CDQ coke oven primary dedusting system and its hanging screen device, belonging to the technical field of CDQ coke oven primary dedusting, which can solve the problem of easy occurrence of bricks and bricks in the retaining wall of the existing CDQ coke oven primary dust collector. collapse problem. The hanging screen device used for the primary dust removal system of CDQ coke oven of the present invention comprises: a hanging screen made of metal material, inside which is provided with a cooling water channel, and the two ends of the cooling water channel are water inlet and water outlet respectively; the hanging unit, It is used to hang the hanging screen, and at least the lower part of the hanging screen is located in the settling chamber of the CDQ coke oven primary dust removal system; the water supply unit is connected with the water inlet and the water outlet of the hanging screen, and is used to provide cooling water to the hanging screen.
Description
Technical field [0001] The invention belongs to the field of dust removal technology of the dry extinguishing coke oven, and specifically, a dry extinguished coke oven once dust removal and its hooding device. Background technique [0002] The dry extinguishing coke oven utilizes an inert gas (such as nitrogen) as a recycle gas produced with a blazing oven production, and the coke temperature is lowered to extinguish. Obviously, a large amount of coke will be carried in the circulating gas that completes the quenching, which is to be used after a dust collector, waste heat boiler, secondary dust collector, circulating fan, heat pipe heat exchanger, etc. to be used for extinguishing. [0003] Among them, the primary dust collector of the dry-extinguished coke oven mainly includes a retaining wall made from the A-stage mullite, and the circulating gas of the quench is blocked by the retaining wall, wherein the coke carried is on the wall due to inertia. During the gray struggle bel...
