Application of anti-fluctuation diffusion curve in gas collecting pipe diffusion control device of coke furnace

Abstract

The invention relates to an application of anti-fluctuation diffusion curve in the gas collecting pipe diffusion control device of a coke furnace. In the method, with a PLC control cabinet as the core, the motion of the diffusion valve executing mechanism of the gas collecting pipe is controlled through the continuous monitoring of the pressure of the gas collecting pipe, the fluctuation of the pressure is maintained within a reliable range, and the sequential motions of the associated ignition device, steam fire collection and smoke abatement valve and steam fire extinguishing valve are controlled, so that the igniter, the diffusion executing mechanism, the fire collection valve and the fire extinguishing valve execute corresponding matching motions according to certain logic. By establishing a set of effective mathematical model for pressure and diffusion control, the optimal scheme can be achieved, so that raw gas can be burnt at the torch burner and the diffused gas can be burnt without smoke. The invention has the advantages of rapid response, safety and reliability, good burning effect and environmental protection.

Description

technical field [0001] The invention relates to a method for controlling the emission of a coke oven gas collecting pipe in the coking industry. Background technique [0002] Energy and environmental issues have become the focus of attention in the world. The development of environmental protection technology in the field of coking is an important symbol of the perfection of modern coking technology. At the same time, the development of automation technology such as computer control has played an important role in improving labor productivity, improving product quality, reducing energy consumption and controlling pollutants. [0003] The application fields and process conditions of the waste gas release control device of the coke oven gas collection pipe: the equipment is installed on the discharge pipe of the coke oven gas collection pipe and in the control room; When the pressure is too high or the blower fails, the gas will leak in large quantities, pollute the environme...

AI Technical Summary

Problems solved by technology

[0004] The early coke ovens were manually operated in terms of gas discharge and pressure control. The response speed was slow, there were many human factors, the working conditions on site were poor, and the degree of danger to workers was great. At the same time, it was difficult to manually ignite the ignition, and the timeliness of ignition could not be guaranteed. Even if it is not ignited, it will pollute the environment greatly
