Water-seal smoke guide main pipe device of ground station dust removing system of coking furnace

Abstract

The invention relates to a water-seal smoke guide main pipe device of a ground station dust removing system of a coking furnace. One end of a smoke guide main pipe main pipeline is communicated with the upper end of a U-shaped water-seal pipeline, and the other end is connected with one end of a water-seal plate; the other end of the water-seal plate extends to the middle of the U-shaped water-seal pipeline; water is stored in the U-shaped water-seal pipeline; a U-shaped smoke guide pipe is arranged in a U-shaped horizontal pipeline and is communicated with a coke guide gas collecting hood through a smoke hood smoke guide pipe; the bottom of the U-shaped water-seal pipeline is communicated with a waste residue drainage device; an overflow device is arranged on the upper part of the U-shaped water-seal pipeline; and the coke guide gas collecting hood is connected with a coke guide into integer whole. The water-seal smoke guide main pipe device is used for sealing the U-shaped smoke guide pipe during the movement of the coke guide gas collecting hood, can enable a smoke gas guided to a main pipe through the U-shaped smoke guide pipe not to be leaked outwards no matter the coke guidestops or moves in the coaling and coke discharge process of the coking furnace because the U-shaped smoke guide pipe is in the encircling and sealing state of the water inside the U-shaped water-sealpipeline, and can ensure that the smoke gas obtained through coaling and coke discharge is completely guided into the smoke guide main pipe main pipeline without depending on any docking equipment, thereby preventing the smoke gas leakage.

Description

technical field [0001] The invention relates to a flue gas conveying technology used in a coke oven dust removal ground station system. Background technique [0002] The "flap door type pipeline docking device" is a common equipment used for flue gas transportation in the coke oven dust removal ground station. The flap door pipeline docking device has a large amount of air leakage, a large amount of maintenance during operation, and requires a large amount of power for the induced draft fan, etc. shortcoming. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and to provide a water-sealed smoke-guiding dry pipe device with small air leakage, less maintenance and energy saving. [0004] The present invention is realized in this way: [0005] There is a main pipe 3 of the smoke guide pipe, one end of which is connected with the upper end of the U-shaped water seal pipe 8, and the other end is connected w...
