Description

Technical Field

[0001] The invention relates to the technical field of dust removal and hydrogen sulfide removal in coal mines, and in particular to a hydrogen sulfide removal and dust reduction treatment device for a coal mining working face in an underground coal mine. Background Art

[0002] In coal mining, especially in the working face area of ​​coal mining, when mining coal, the mining working face will not only produce a large amount of dust, but also often release a certain amount of hydrogen sulfide gas. Hydrogen sulfide is a flammable acidic gas, colorless, and has a rotten egg smell at low concentrations. It is highly toxic and will not only cause nausea, vomiting and other adverse reactions in nearby people, but also hydrogen sulfide is a flammable hazardous chemical. When mixed with air, it can form an explosive mixture and cause combustion and explosion when exposed to open flames and high heat. Therefore, in the process of mine mining, especially in the working face area, hydrogen sulfide poses a great safety hazard to production safety and personal safety. In this regard, according to relevant regulations, the maximum allowable concentration of hydrogen sulfide in mine air is 0.00066%.

[0003] Based on this, at present, for the mining area of ​​the working face, it is generally necessary to set up equipment for treating hydrogen sulfide. The current equipment is generally a simple spraying of alkali solution, such as calcium carbonate solution, sodium hydroxide solution, sodium bicarbonate solution, etc. However, the current spraying equipment generally simply uses a spray pump and a nozzle to spray. However, this method cannot effectively carry out targeted spraying according to the actual mining situation, which leads to either too much or too little spraying. Excessive spraying not only affects the cost, but also causes too much water in the mining working face and affects the surrounding environment, while too little spraying cannot completely remove the hydrogen sulfide gas, resulting in safety hazards.

[0004] Therefore, it is necessary to provide a device that can reduce dust in coal mining working surface and effectively remove hydrogen sulfide to solve the above problems. Summary of the invention
