Device and method for controlling diffusion of gas collecting pipe

Abstract

The invention relates to a device and a method for controlling the diffusion of a gas collecting pipe. The device comprises a burner, a diffusion pipe, an igniter cabinet, a control cabinet, a diffusion valve, a diffusion valve executing mechanism, a fire collection valve, a fire extinguishing valve and a pressure transmitter, wherein the burner is positioned at the upper part of the diffusion pipe, the igniter cabinet is connected with the burning torch on the burner through a cable, the fire collection valve is connected with the fire collection pipe of the burner, and the fire extinguishing valve is connected with the fire extinguishing pipe of the burner; the diffusion valve is positioned at the joint of the diffusion pipe and the gas collecting pipe and connected with the diffusion valve executing mechanism, and the pressure transmitter is arranged on the gas collecting pipe at the inlet of the diffusion pipe; and 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, the sequential motions of the associated ignition device, the steam fire collection and smoke abatement valve and the steam fire extinguishing valve are synchronously controlled to achieve the optimal scheme. 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 coke oven gas collecting pipe emission control device and control method 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, a large amount of gas will leak, pollute the environment, ...

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
