The invention discloses a coal mine underground ultrasonic atomization and desulfurization device. The coal mine underground ultrasonic atomization and desulfurization device comprises a desulfurization box and a controller, wherein an air inlet is formed in the front end of the desulfurization box; a hydrogen sulfide sensor is mounted at the entrance of the air inlet; a metal dust removal net ismounted at the middle part in the air inlet; an air suction fan is mounted at the rear part in the air inlet; an air outlet is formed in the rear end of the desulfurization box; a ridge-shaped demisting net is mounted close to the air outlet in a collection box; an upper hydrogen sulfide atomization mechanism is mounted at the top of the desulfurization box; an atomization and waste liquid collection mechanism is arranged at the bottom of the desulfurization box and comprises a lower hydrogen sulfide atomization mechanism and the waste liquid collection mechanism; the waste liquid collection mechanism is located at the rear side of the lower hydrogen sulfide atomization mechanism; the lower hydrogen sulfide atomization mechanism and the upper hydrogen sulfide atomization mechanism are located at the front side of the ridge-shaped demisting net and are jointly used for removing hydrogen sulfide gas. The coal mine underground ultrasonic atomization and desulfurization device is capable of effectively treating the underground hydrogen sulfide gas and improving the underground working environment; meanwhile, the coal mine underground ultrasonic atomization and desulfurization device can be used for removing the dust and removing other harmful gases.
Description
Technical field [0001] The invention belongs to the technical field of coal mine safety treatment, and in particular relates to a coal mine underground ultrasonic atomization desulfurization device. Background technique [0002] With the continuous improvement of my country's energy requirements and continuous economic growth, my country's coal mining is increasing, followed by the emergence of hydrogen sulfide gas in coal mines. Hydrogen sulfide gas is a highly toxic combustible gas, colorless, with the smell of rotten eggs, when the concentration is higher than 760mg / m 3 When the concentration is too high, it can cause pulmonary edema, bronchitis, pneumonia and other diseases. If the concentration is too high, it can cause death, and seriously endanger the health and life safety of underground workers. [0003] At present, the treatment methods of hydrogen sulfide gas in coal mines in our country mainly include adjusting air volume, spraying lye, and pre-injecting lye, but the ef...
