Embodiment Construction

[0054] The basic idea of ​​the present invention is to determine the first decoupling parameter by using the preset control parameters and the pressure values ​​of the gas collectors, and use the predetermined coupling coefficient to determine the second opening for eliminating the coupling effect between the gas collectors The adjustment amount, and the superposition result of it and the first opening adjustment amount is used as the adjustment amount of the butterfly valve to adjust the butterfly valve.

[0055] In order for those skilled in the art to have a better understanding of the present invention, the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and description.

[0056] Please refer to FIG. 1 , which is a structural schematic diagram of Embodiment 1 of a multi-coke oven gas collector pressure control device according to the present invention.

Abstract

This invention has publicized a more coke oven gathering of gas pipe pressure control device. It comprises the pressure gathering unit which is used to gather various collecting pipes' value of pressure, the reed valve opening detecting element which is used to examine various collecting pipes' reed valve's opening, the reed valve regulating unit which is used to adjust collecting pipe's reed valve's opening, the first control unit which is used to gathering unit gather value of pressure with the controlled variable which establishes in advance determining that the first opening adjustment quantity according to the pressure. This first opening adjustment quantity with the decoupling coefficient product determination which establishes in advance for the second opening adjustment quantity, the union current reed valve's opening, controls states the reed valve regulating unit with to state the second opening adjustment quantity according to this first opening adjustment quantity the superimposition result to make the adjustment to the reed valve. At the same time, this invention has also publicized a coke oven gathering of gas pipe pressure control method. Using this invention may reduce the pressure perturbation between various collecting pipes' effectively.

Description

technical field [0001] The invention relates to the field of automatic control, and more specifically relates to a method and device for controlling gas collecting pipes of multiple coke ovens. Background technique [0002] The role of the coke oven gas collection pipe is to collect the gas exported from each carbonization chamber, and recover it through the fan after cooling. The gas collector pressure is an important control index that affects coke quality, gas production and coke oven life. If the pressure of the air collecting pipe is too low, the carbonization chamber will inhale air and cause coke to burn, which will affect the life of the furnace body, reduce the quality of coke, and even endanger the safe operation of the blower in serious cases; if the pressure is too high, the coke oven will cause smoke and fire, which will pollute the environment A large amount of energy is wasted again, and catching fire can reduce the heating intensity of the furnace column, sh...
