[0002] Coke oven pushers, material distribution trolleys and other equipment are the main equipment for the production and operation of coke ovens. Coke ovens produce a large amount of coal gas during the coking process. The coal gas can be recovered through gas pipelines to the chemical production process, and ammonia, coal tar and other products can be produced through distillation, separation, washing and other methods. When the coke oven is discharging coke or loading coal, the furnace door or coal loading port needs to be opened. The coal gas inside the coke oven overflows through the furnace door or coal loading port. The coal gas contains toxic and harmful gases, which pollutes the environment greatly. The coal loading car or coke pusher is a horizontally moving device with a horizontal moving distance of more than 200 meters. It is difficult to connect the recovered coal gas to the coke oven gas main pipeline. During the coke discharging and coal loading operations of the coke oven, a large amount of coal gas overflows, causing great pollution to the production area environment and a great impact on the health of the operators.

[0006] A partition plate with an L-shaped cross section is fixed on the water seal groove. The end of the horizontal section of the partition plate is sealed and fixedly connected to the upper left edge of the water seal groove. The vertical section of the partition plate is located in the middle of the water seal groove and extends vertically downward into the water seal groove. The upper left side of the water seal groove is connected to the main pipeline. The water level in the water seal groove is below the lower edge of the vertical section and is lower than the main pipeline. The water seal groove is connected to one side of the main pipeline to form a watertight compartment, and the other side of the water seal groove forms an open compartment.
[0007] It also includes a U-shaped elbow, which passes through the open bin downward into the water seal groove, passes around the lower end of the partition plate and extends to the top of the watertight bin. The other end of the U-shaped elbow is connected to the dust hood, and the movement of the dust hood drives the U-shaped elbow to move.
[0008] Furthermore, the water seal groove is connected to a water supply pipe, and the water supply pipe is connected to an electromagnetic water level control valve for limiting the water level; when the water level is lower than the set water level, the electromagnetic water level control valve starts to supply water.
[0009] Furthermore, a drain outlet is provided at the lower end of the water seal groove, and a drain valve is connected to the drain outlet.
[0010] The beneficial effects of the utility model are:
[0011] By adding 200-meter-long U-shaped water seal grooves, U-shaped elbows and other equipment next to the tracks of coke pushing cars and coal loading cars, a sliding connection between the dust collection pipes of coke pushing cars and coal loading cars and the gas main pipeline is achieved, which enables the recovery of overflow gas from the coke oven during the coke discharge and coal loading process and reduces environmental pollution.
