Problems solved by technology

However, in fully mechanized mining, it takes a lot of time to install and fix large-scale equipment. If there is a danger of explosion, the equipment cannot be withdrawn in a short time. If an explosion occurs, it will cause great damage to the equipment and cause irreparable damage. Economic losses

Abstract

The invention discloses fully automatic gas explosion proof equipment, comprising a gas monitoring system, an explosion proof system, an alarm system and a control system. The gas monitoring system is used for monitoring gas concentration and tunnel temperature in real time, and the gas concentration and the tunnel temperature are compared with the set values, when the danger of gas explosion exists, the control system can automatically control the explosion proof system to quickly release a large quantity of inert gases to reduce the gas concentration, at the same time, the alarm system is used for sending out alarm signals to warn the operators. The system can automatically realize the function of explosion proofness, is simple in structure and quick in response and can effectively improve the safety of automatic coal mining.

Description

technical field [0001] The invention relates to a gas explosion-proof device, in particular to a fully automatic gas explosion-proof device. Background technique [0002] The main components of coal mine gas are alkanes, of which methane accounts for the vast majority, and a small amount of ethane, propane, and butane. In addition, it generally contains hydrogen sulfide, carbon dioxide, nitrogen, and moisture, as well as trace amounts of inert gases, such as helium and argon. Wait. When the oxygen concentration in the air reaches 10%, the gas concentration is between 5-16%. If an open flame is encountered, an explosion will occur, directly threatening the lives of miners. Every coal mine will inevitably produce gas, which is a by-product of coal mines, and the difference lies in the concentration. The high temperature and high pressure produced by the gas explosion will cause the gas near the explosion source to impact outward at a great speed, causing casualties, destroyi...
