A kind of coal mine underground gas purification device and purification method thereof

Abstract

The invention discloses a coal mine underground gas purification device and a purification method thereof, relating to the technical field of gas purification, in particular to an underground coal mine gas purification device and a purification method thereof, comprising a gas purification box and a cleaning brush, the gas purification box A driving cylinder is installed inside, and the right side of the driving cylinder is connected with a telescopic rod, the right side of the telescopic rod is connected with a linkage plate, and the right side of the linkage plate is installed with a fixed pile, and the cleaning brush is installed on the telescopic column away from the fixed At the position of the horizontal center line of the pile, a water-absorbing cotton board is placed above the elastic board, and heating rods are installed on the left and right sides above the water-absorbing cotton board. The coal mine underground gas purification device and its purification method are provided with a driving cylinder that can drive the linkage plate to move to the right through the telescopic rod. During the process of the linkage plate moving to the right, it can drive the fixed pile and the cleaning brush to move accordingly, and the moving cleaning brush can be separated. Clean the separation screen and 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 ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a coal mine underground gas purification device and its purification method, which solves the problem that the process of the existing coal mine underground gas purification device and its purification method proposed in the above-mentioned background technology is cumbersome and takes a long time , affect the progress of coal mine mining, and the existing gas purification device lacks its own cleaning function, which easily affects the subsequent purification function of the device
