Problems solved by technology
At present, the hydrogen sulfide gas removal technology in the roadway wind flow is mainly through manual spraying of alkaline solution, and the manual spraying of alkaline solution is mainly adjusted and controlled manually, which has great personal safety hazards, and the benefits and economic performance are obviously insufficient
[0003] In the published literature, there are mines that use automatic spraying to remove dust, and have achieved good results, but so far there has been no report on the removal of hydrogen sulfide by automatic spraying, so can automatic spraying be used to develop a dedusting The device for removing hydrogen sulfide is an urgent problem to be solved

The invention relates to an automatic hydrogen sulfide removal device in tunnel airflow, and aims at effectively solving the problem of removal of hydrogen sulfide. An automatic liquid dosing system is communicated with a water inlet pipe and a liquid storage tank; a low-speed motor above the liquid storage tank is connected with a stirrer; a pressure sensor is arranged in the liquid storage tank; an outlet of the liquid storage tank is connected with a spray bracket; a booster pump is arranged on a pipeline between the liquid storage tank and the spray bracket; an electromagnetic valve is arranged above an atomization nozzle on the spray bracket; a hydrogen sulfide concentration sensor and an infrared induction detector are arranged on two sides of the spray bracket; an air velocity sensor is arranged on one side of the spray bracket; and the hydrogen sulfide concentration sensor, the infrared induction detector, the booster pump, the pressure sensor, the automatic liquid dosing system, the electromagnetic valve and the air velocity sensor are all connected with a control host computer. The automatic hydrogen sulfide removal device is simple to operate, safe and practical; when the concentration of hydrogen sulfide exceeds the limit, automatic spray is carried out according to the concentration of the hydrogen sulfide and the air velocity; and the automatic hydrogen sulfide removal device is an effective and economical method for automatic removal of the hydrogen sulfide in tunnel airflow.
Description
technical field [0001] The invention relates to a device for automatically removing hydrogen sulfide from air flow in a roadway. Background technique [0002] Hydrogen sulfide (H 2 S) is a colorless and highly toxic gas with the smell of rotten eggs, which mainly damages the central nervous system and respiratory system of workers and seriously threatens the personal safety of workers. my country's "Coal Mine Safety Regulations" stipulates that the maximum allowable concentration of hydrogen sulfide in mine air flow is 6.6ppm . At present, the hydrogen sulfide gas removal technology in the roadway wind flow is mainly through manual spraying of alkaline solution, and the manual spraying of alkaline solution is mainly adjusted and controlled manually, which has great personal safety hazards, and the benefit and economic performance are obviously insufficient. [0003] In the published literature, there are mines that use automatic spraying to remove dust, and have achieved go...
