Guide device for exhaust gas emitted by rising pipe of coke oven

Abstract

The invention relates to a guide device for an exhaust gas emitted by a rising pipe of a coke oven. The guide device comprises multiple layers of flow guide pipes, a conical air cap and a mounting bracket; each flow guide pipe is composed of a straight pipe on the upper part and a conical pipe on the lower part; the inner diameter of lower opening of the conical pipe is more than the inner diameter of upper opening; multiple layers of flow guide pipes are connected with each other in turn from top to bottom; the diameters of straight pipes and corresponding conical pipes are decreased progressively; the upper end of the straight pipe of the lower layer of flow guide pipe is inserted into the conical pipe of the adjacent upper layer of flow guide pipe; multiple layers of flow guide pipes are fixed above the rising pipe through the mounting bracket; the conical air cap is fixedly connected with the top layer of flow guide pipe. The guide device provided by the invention is suitable for wholly closed coke oven, is used for guiding the exhaust gas emitted in the rising pipe out of a closed greenhouse, is capable of guaranteeing that the exhaust gas emitted by the rising pipe of the coke oven in the closed greenhouse cannot be gathered during a coke pushing process and also is capable of guaranteeing an excellent operation environment in a operation zone on furnace top in the closedgreenhouse.

Description

technical field [0001] The invention relates to the technical field of coke oven production, in particular to a flue gas guiding device for a riser tube of a coke oven. Background technique [0002] At present, the state requires that the furnace body be covered and sealed in the built-up areas of cities in key areas, and the exhaust gas be collected and treated. According to the requirements, the coke oven body, machine side and coke side vehicle steel structure greenhouses should be sealed as a whole. When the coke oven is in production, most of the gas generated in the carbonization chamber enters the gas collecting pipe through the rising pipe, and some of the gas is transported to the coal charging and dust removal ground station through the coal charging interface valve for purification. But before the start of coke pushing, the water seal valve at the top of the ascending pipe will be opened, and the bridge pipe connecting the ascending pipe and the gas collecting pi...

AI Technical Summary

Problems solved by technology

If the coke oven gas cannot be exported smoothly in the closed greenhouse, it will affect the working environment in the closed greenhouse. When a large amount of gas accumulates in the closed greenhouse, it will pose a major threat to the safe production and operation of the coke oven.
