Description

Liquid level and air pressure adjusting device

Technical Field

The utility model belongs to the technical field of raw gas pressure regulation of a single carbonization chamber of a coke oven, and particularly relates to a liquid level and gas pressure regulating device which is suitable for on-line upgrading and reconstruction of the coke oven and is suitable for raw gas pressure regulation of the single carbonization chamber of a newly-built coke oven.

Background

Coke ovens, a furnace typically built of refractory bricks and refractory blocks, are used to char coal to produce coke. The kiln for making coke by using coal is a main thermal equipment for coking. The modern coke oven is a horizontal chamber type coke oven which mainly aims at producing metallurgical coke and can recover coking chemical products, and comprises an oven body and accessory equipment. The coke oven body consists of a furnace top, a combustion chamber, a carbonization chamber, a chute area, a regenerator and the like, and is connected with a chimney through a flue. Modern coke ovens are generally the same in basic structure, but can be divided into many types due to different coal charging modes, heat supply modes and fuels used.

The crude gas pressure control of the coke oven carbonization chamber in the prior on-line operation is mainly realized by regulating the crude gas pressure of a segmented gas collecting pipe. In the coke oven production, because the production states of all the coking chambers are different, the pressure fluctuation of the raw coke oven gas in a single coking chamber is easy to cause. In the initial stages of coal charging and coking, the crude gas generation amount is large, and the pressure of the crude gas at the bottom of a coking chamber is too large, so that the inorganization leakage of the crude gas at various positions of a coal charging hole, a furnace wall, a furnace door, a furnace body and the like of a coke oven can be caused, and the pollution to the atmospheric environment is caused; in the coking end stage, the generation amount of raw gas is small, negative pressure is easily formed at the bottom of the coking chamber, and air is leaked and sucked into the coking chamber, so that coke burning loss and furnace body damage are caused.

Therefore, the raw gas pressure adjusting device which is connected with a single carbonization chamber and can be suitable for the on-line upgrading and reconstruction of the coke oven and a newly-built coke oven is developed, so that the problem of the pressure fluctuation of the raw gas in the single carbonization chamber is solved, and the device is worthy of further research.
