Abstract

The invention relates to a method for drawing raw coal gas out of coke oven. A device used comprises a riser water seal cover opening and closing control device on a coke oven side or coke side, a riser water seal cover, a riser lead-out device, a cooled low-pressure ammonia water spraying device, a high-pressure ammonia water spraying device, a bridge tube, a water seal valve body, a water seal valve disk, a water seal valve disk opening and closing control device and a gas collecting tube, and is characterized in that: the method adopts a downward inclined riser lead-out device for preventing ammonia water from flowing back, and the two sides of the riser lead-out device are connected with the bridge tube and a riser water seal seat respectively. The device has the advantages that: raw coal gas generated in production in coke oven can be led into the gas collecting tube smoothly without returning ammonia water; the drawback that sealing material in the valve disk is washed out of the socket of the valve disk when the U-shaped valve disk is washed by high-pressure ammonia water is overcome; and the operation is flexible, the overhaul is convenient, the structural arrangement is reasonable, and the energy-saving and environment-protection effects are obvious, and the like.

Description

technical field

[0001] The invention relates to a new method for exporting raw gas from coke ovens, which can smoothly lead the raw gas in the carbonization chamber into the gas collecting pipe during production, and can quickly close the water seal valve and quickly open the water seal cover of the rising pipe when the coke is discharged, and is safe in operation; especially The utility model relates to a novel coking oven raw gas exporting device. Background technique

[0002] Coking ovens at home and abroad export the raw coal gas produced in the carbonization chamber through the gas collection system on the top of the furnace during production, spray ammonia water on the bridge pipe to cool down, and the cooled raw gas is sent to the In the follow-up section, raw gas is exported through the rising pipe export device without slope, the bridge pipe, the valve body and then enters the gas collecting pipe; the socket between the bridge pipe and the valve body is a simple U-s...
