Coal mine underground gas purification device and purification method thereof

Abstract

The invention discloses an underground coal mine gas purification device and a purification method thereof, and relates to the technical field of gas purification, in particular to an underground coal mine gas purification device and a purification method thereof. The device comprises a gas purification box and a cleaning brush, a driving air cylinder is installed in the gas purification box, the right side of the driving air cylinder is connected with a telescopic rod, a linkage plate is connected to the right side of the telescopic rod, a fixing pile is installed on the right side of the linkage plate, the cleaning brush is installed at the position, away from the horizontal center line of the fixing pile, of the telescopic column, a water absorption cotton plate is arranged above an elastic plate, and heating rods are installed on the left side and the right side of the upper portion of the water absorption cotton plate correspondingly. According to the underground coal mine gas purification device and the purification method thereof, a driving air cylinder is arranged and can drive a linkage plate to move rightwards through a telescopic rod, a fixed pile and a cleaning brush can be driven to move along with the linkage plate in the rightward moving process, and the moving cleaning brush can sweep a separation net plate and the gas purification box.

Description

technical field [0001] The invention relates to the technical field of gas purification, in particular to a coal mine underground gas purification device and a purification method thereof. Background technique [0002] Gas is formed by the decomposition of cellulose and organic matter by anaerobic bacteria in the initial stage of coal accumulation by ancient plants. In the environment of high temperature and high pressure, while coal is formed, gas continues to be generated due to physical and chemical effects. Gas is a colorless, odorless gas, hardly soluble in water, does not support combustion and cannot sustain breathing. When it reaches a certain concentration, it can cause people to suffocate due to lack of oxygen, and can burn or explode. Gas exists in a free state and an adsorbed state in coal or surrounding rock. In coal mining operations, it is necessary to purify underground gas to ensure the smooth progress of coal mining. Therefore, a coal mine underground gas ...
