Abstract

The invention relates to the technical field of waste gas treatment, and discloses a system for discharging waste gas and waste water in a mine by using oxygen-enriched tail gas of a PSA nitrogen making machine, an air compressor is connected with an air purification device through a pipeline, the air purification device is connected with an air storage tank through a pipeline, and the oxygen-enriched tail gas discharged by the PSA nitrogen making machine is conveyed into the mine through a gas conveying pipe 7. Meanwhile, the oxygen content in the conveyed oxygen-enriched tail gas is higher than that of normal air, and the oxygen-enriched tail gas is neutralized with low-oxygen-content air generated by breathing of workers in the mine, so that the oxygen content in the air is increased, and the suffocation risk of the workers in the mine is reduced; the oxygen-enriched tail gas discharged by the PSA nitrogen making machine still contains a certain pressure, so that a pressure difference can be formed in the mine to balance the pressure of underground water, and the occurrence probability of water permeation accidents of the underground mine is reduced. And similarly, the waste water in the mine is not easy to flow everywhere, so that the probability of danger is reduced.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a system for removing waste gas and waste water in a mine by using the oxygen-enriched tail gas of a PSA nitrogen generator. Background technique [0002] The current common PSA nitrogen generator system uses adsorption to produce nitrogen. The nitrogen production system adopts the working principle of pressure swing adsorption (that is, the principle of PSA). Pressure swing adsorption is a new type of gas adsorption and separation technology. PSA nitrogen production is based on the principle that nitrogen and oxygen molecules are different in size. When passing through carbon molecular sieves under a certain pressure, oxygen molecules are adsorbed and nitrogen is separated. Compressed air is used as raw material , to produce nitrogen as an industrial production equipment. [0003] Pressure swing adsorption nitrogen production equipment is mainly composed of five pa...
