Description

Technical Field

[0001] The invention belongs to the technical field of coal mine hydrogen sulfide purification, and in particular relates to a hydrogen sulfide purification device. Background Art

[0002] In coal mining, in addition to the more common dangers caused by gas leaks, hydrogen sulfide gas outflows often cause dangers. Hydrogen sulfide is a flammable acidic gas, colorless, with a rotten egg smell at low concentrations, and a sulfur smell at extremely low concentrations, and is highly toxic. Hydrogen sulfide is a flammable hazardous chemical that can form an explosive mixture when mixed with air, and can cause combustion and explosion when exposed to open flames and high heat. Hydrogen sulfide is an acute and highly toxic gas. Inhaling a small amount of high-concentration hydrogen sulfide can be fatal to the human body in a short period of time, and low concentrations of hydrogen sulfide can also affect the eyes, respiratory system and central nervous system. Hydrogen sulfide is a strong neurotoxin. Even a small amount of inhalation can have a strong irritating effect on the mucous membrane. Inhaling high concentrations of hydrogen sulfide in a short period of time can cause tearing, eye pain, foreign body sensation in the eyes, photophobia, blurred vision, runny nose, burning sensation in the throat, coughing, chest tightness, headache, dizziness, fatigue, confusion, etc. Severe cases may cause cerebral edema and pulmonary edema. At extremely high concentrations, people may suddenly fall into a coma within seconds and die suddenly. High concentrations may cause conjunctival edema and corneal ulcers. Long-term low-concentration exposure may cause neurasthenia syndrome and autonomic nervous system dysfunction.

[0003] In the process of coal mining, in the mining process of coal seams in some areas with more hydrogen sulfide gas, it is necessary to take corresponding treatment and purification measures for the outflow of hydrogen sulfide gas at all times. The current common purification measure is to spray an atomized liquid of alkali solution into the air so as to neutralize and absorb the hydrogen sulfide gas. However, the current spraying method is relatively simple, and generally dense nozzles are used to ensure the spray area and purification area, but this method is difficult to ensure the maximization of the spray treatment area in the case of rapid and large-scale outflow. At the same time, spraying only by increasing the number of nozzles or the length of the nozzle not only occupies a large space, but also affects the construction, and the effect after spraying is not good, affecting the quality of purification treatment.
