Controlled auto-pumping type coke oven side entrance smoke gas collecting apparatus

Abstract

The invention relates to a side fire door flue gas collecting device for controllable automatic suction type coke oven, consisting of a flue gas conveying pipe, a controllable automatic valve, a lower dust-collector hood, a pipe support and the control system of the automatic valve, wherein, the upper part of a coke oven stay is provided with the pipe support; the flue gas conveying pipe is positioned at the upper part of the pipe support; the controllable automatic valve which is connected with lower part of the flue gas conveying pipe is positioned between two adjacent oven stays; the lower dust-collector hood is connected with the lower part of the controllable automatic valve and closes the space formed by the two adjacent oven stays and positioned at the upper part of a coking chamber. The device is suitable for side dust removal of various tamping coke oven during coal charging without any renovation of the coke oven body and any influence on technical operation and service life of the coke oven; moreover, the device has the advantages of flexible adjustment, accurate control, easy maintenance, reasonable structural layout, less investment, no extra occupation of land, outstanding energy-saving effect, no flue gas leakage and no secondary pollution, etc.

Description

technical field [0001] The invention relates to a special device for effectively controlling the leakage of flue gas at the side of the coke oven machine when charging coal in a tamping coke oven, in particular to a controllable automatic suction type coke oven machine side flue gas collection device. Background technique [0002] At present, there is no effective way to deal with the flue gas emitted from the side door of the coke oven machine during the coal charging process of tamping coke ovens at home and abroad, which has become an important factor restricting the development of tamping coking technology. With the continuous improvement of environmental protection requirements in countries all over the world, it is increasingly urgent to solve this difficult problem that restricts the development of tamping coking technology. The dust removal method used in tamping coke ovens at home and abroad is mainly coal-loading and dust-removing vehicles. The method is mainly to ...
