Description

Technical Field

[0001] The present invention relates to the technical field of flow velocity sensors, and more specifically to a coal mine tunnel air flow velocity detection device and a detection system. Background Art

[0002] Mine air refers to the air after entering the mine. Mechanical or natural ventilation is used to allow ground air to enter the mine and flow in a directional and quantitative manner in the tunnels. The whole process from ground air entering the mine to its final discharge from the mine is called mine ventilation. Common harmful gases in mine air include carbon monoxide (CO), hydrogen sulfide (H2S), nitrogen dioxide (NO2), sulfur dioxide (SO2), ammonia (NH3), hydrogen (H2), etc. Gas refers to the harmful gas mainly composed of coal-bed methane in the mine, and sometimes methane is referred to alone. Gas is a A colorless, tasteless, odorless gas that can burn or explode. It is insoluble in water and has a higher diffusion rate than air. The gas is non-toxic, but when the concentration is very high, it can cause suffocation. Mine gas does not support combustion, but when it is mixed with air to a certain concentration, it can burn and explode when encountering fire. Gas explosions will produce three fatal factors: explosion flames, explosion shock waves and toxic and harmful gases. Gas explosions not only cause a large number of casualties, but also seriously destroy mine facilities and interrupt production. Mine gas explosions often cause secondary disasters such as coal dust explosions, mine fires, shaft and tunnel collapses and roof falls.

[0003] Most of the existing coal mine air detection devices are of a relatively short variety and have relatively simple performance. They have certain deficiencies when used. At the same time, the detection gas is relatively single and it is inconvenient to filter the air. The air inside the coal mine contains a lot of coal dust. The large amount of dust adsorbed on the air detector greatly affects the accuracy of the detection. At the same time, the detector often fails, and the staff frequently cleans and replaces the air detector, which increases the cost of coal mine enterprises and has poor practicality. It cannot meet the actual use needs. Summary of the invention
