Simulation device for removing hydrogen sulfide from roadway airflow

Abstract

The invention belongs to the technical field of mine production equipment, and particularly relates to a simulation device for removing hydrogen sulfide from roadway airflow. The simulation device comprises a simulated roadway, an air generating device, a hydrogen sulfide generating device, a spraying device and a sampling hole, wherein the air generating device is arranged at a starting port of the simulated roadway, the hydrogen sulfide generating device is connected to the air generating device, the spraying device is arranged in the middle of the simulated roadway, and the middle or the tail end of the simulated roadway is provided with the sampling hole; the simulated roadway is long-cylinder-shaped; the air generating device is a fan at the air inlet position of the starting port ofthe simulated roadway; the hydrogen sulfide generating device comprises a hydrogen sulfide gas bottle and a nitrogen gas bottle which are each provided with a valve and are connected in parallel; thespraying device comprises a plurality of rows of spraying pipes which are arranged above the middle part of the simulated roadway; a plurality of nozzles are arranged on the spraying pipes; the sampling device is a sealed box body; a sampling bag which can be taken out is arranged in the box body; and the box body is connected with a vacuum pump. According to the simulation device, the problem ofthe hydrogen sulfide contained in the roadway airflow in the mine construction can be better simulated and can be better guided, and therefore a foundation is laid for safe and stable production.

Description

technical field [0001] This application belongs to the technical field of mine production equipment, and specifically relates to a patent application for a simulation device for removing hydrogen sulfide in air flow in a roadway. Background technique [0002] Hydrogen sulfide (H 2 S) is a colorless, suffocating and irritating highly toxic gas with the smell of rotten eggs. It mainly damages the central nervous system and respiratory system, and seriously threatens the personal safety of underground workers. The "Coal Mine Safety Regulations" stipulates that the maximum allowable concentration of hydrogen sulfide in mines is 6.6 ppm. Therefore, the hydrogen sulfide in the mine production process must be removed in time to ensure production safety. [0003] There are generally two ways to remove hydrogen sulfide gas in the air flow of the existing mine roadway: one is to improve ventilation; the other is to spray alkaline solution. In response to this problem, the applicant...

Problems solved by technology

In response to this problem, the applicant once designed and developed the "Automatic Hydrogen Sulfide Removal Device in Roadway Air Flow" (application number: 2015100823605), but this technical solution is mainly used for the automatic removal of hydrogen sulfide in actual production. It was found that due to different mine structures, different production methods, and different hydrogen sulfide production volumes, which method can be used to remove hydrogen sulfide more effectively and thoroughly often requires multiple tests before it can be determined, which affects the production progress to a certain extent. It also brings the risk of safe production
