Pressure control method, equipment, storage medium and device in coking process of carbonization chamber

Abstract

The invention provides a pressure control method, equipment, a storage medium and a device in a coking process of a coking chamber. After coal charging of a coke oven is completed, the coke oven is switched to a coking state, piston driving equipment is controlled to drive a piston assembly valve element to be adjusted to a safe position, low-pressure sprayed ammonia water is gathered in a tooth socket cup body, and after the liquid level rises to a specified height, the piston assembly valve element is controlled to be adjusted to the safe position; the pressure control system triggers a coking instruction, timing is conducted, and the coking time is obtained; according to the corresponding relation between the coking time and the pressure value of the carbonization chamber, a coking time pressure control model conforming to the actual pressure value is established; the pressure set value of each stage is calculated according to the coking time pressure control model, and according to the pressure set value, the piston assembly valve core is controlled to move up and down, and the plugging degree of the tooth socket cup tooth socket valve body is controlled, so that the pressure of the carbonization chamber in the whole coking period is controlled, and the interior of the carbonization chamber is always kept in a positive pressure state in the whole coking period. The negative pressure state of the bottom of the carbonization chamber in the middle and last stages of coking is avoided.

Description

technical field [0001] The invention relates to the technical field of coke oven coke production, in particular to a pressure control method, equipment, storage medium and device in the coking process of a carbonization chamber. Background technique [0002] With the development of the iron and steel industry and the adjustment of national industrial policies and environmental protection policies, the requirements for coking, a high-energy-consuming and high-polluting industry, are getting higher and higher. [0003] In the initial stage of coal charging and coking, the amount of waste gas is large, and the pressure at the bottom of the coking chamber is too large, which will cause unorganized leakage of waste gas in many places such as the coal charging hole, furnace wall, furnace door, and furnace body of the coke oven, causing atmospheric leakage. Environmental pollution; in the final stage of coking, the amount of waste gas is small, negative pressure is easily formed at...

AI Technical Summary

Problems solved by technology

[0003] In the initial stage of coal charging and coking, the amount of raw gas generated is relatively large, and the pressure at the bottom of the carbonization chamber is too high, which will cause unorganized leakage of raw gas in many places such as the coal charging hole, furnace wall, furnace door, and furnace body of the coke oven, causing atmospheric pollution. Environmental pollution; in the final stage of coking, the amount of raw gas is small, and the bottom of the carbonization chamber is easy to form a negative pressure, and the air is leaked into the carbonization chamber, causing coke burning and furnace damage
