Description

Technical Field

[0001] The utility model relates to the technical field of gas suppression devices, in particular to a molecular sieve adsorption suppression device for harmful gases in mines. Background Art

[0002] The harmful gases formed in the natural environment during mining are mainly methane, hydrogen sulfide, carbon monoxide, nitrogen oxide, ammonia, and sulfur dioxide. When the concentration of methane or carbon dioxide in the total return air lane or one wing return air lane of the mine exceeds 0.75%, the cause must be immediately identified and dealt with. When the methane concentration in the return air lane of the mining area or the return air lane of the mining working face exceeds 1.0% or the carbon dioxide concentration exceeds 1.5%, work must be stopped, personnel evacuated, and measures taken for treatment. When the methane concentration in the air flow of the mining working face and other work sites, or within 20 meters of the location where the motor or its switch is installed, reaches 1.5%, work must be stopped, power must be cut off, personnel evacuated, and treatment must be carried out. To this end, it is necessary to use a treatment device to remove the toxic gases formed by ore mining.

[0003] However, during the current mining process, the concentration of harmful gases is diluted by airflow in the mine. However, due to some occasional circumstances, the concentration of harmful gases in local areas often exceeds the standard. It is not convenient to spray the liquid mixed with the molecular sieve adsorption inhibitor to the location where the concentration of harmful gases exceeds the limit, which increases the risk of ore mining.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a molecular sieve adsorption and suppression device for harmful gases in mines is proposed. Utility Model Content
