Problems solved by technology

The above-mentioned prior art has the following problems: when the blast furnace gas cabinet causes 95% of the effective cabinet capacity of the blast furnace gas cabinet to fail due to failure of the gas inlet and outlet valves and other reasons, the interlocking closure of the inlet and outlet valves will fail, and the piston will continue to rise, and the gas cabinet will pass through the safety release pipe or even The emergency release pipe releases the gas (non-combustion method); or af

Abstract

The invention relates to an automatic excessive gas diffusing system and belongs to the field of gas distribution and storage projects. The automatic excessive gas diffusing system comprises a vertical burning and diffusing pipe, a diffusing system main gas pipe, a gas regulating valve, a pressure detecting device, a flowmeter, a steam pipeline, a magnetic steam valve, coke oven gas pipeline usedduring burning, a magnetic coke oven gas valve used during burning, a magnetic coke oven gas valve for ignition, a coke oven gas pipeline for ignition, a gasometer system and a diffusing ignition control module. A gasometer capacity signal of a gasometer is introduced into the automatic excessive gas diffusing system. The signal is sent when a gasometer piston rises to a certain height, the automatic excessive gas diffusing system is opened for gas diffusion and burning. The signal is sent after the piston descends to a certain height, the automatic excessive gas diffusing system is closed, excessive gas in a pipe network system and a gasometer in a whole plant is burned and diffused through the automatic excessive gas diffusing system so as to protect the environment and safety of personsnearby the gasometer to the most degree.

Description

technical field [0001] The invention belongs to the field of gas transmission, distribution and storage engineering, and relates to an automatic combustion and release system for excess gas. Background technique [0002] The gas cabinet is a huge device for storing low-pressure gas. It can balance the fluctuation of gas production and sales, and play the role of energy saving and environmental protection. In the case of huge consumption and use, the dry gas holder that uses the weight of the piston itself to generate stable gas pressure has been widely used. This kind of gas holder can stabilize the pressure of the gas pipeline network, stabilize the user's thermal system and improve product quality. beneficial in many respects. [0003] Taking the blast furnace gas cabinet of the iron and steel complex as an example, due to the huge production and sales volume of blast furnace gas and the periodic furnace replacement of hot blast stoves (about 50min / time), the production a...
