Abstract

According to the system for dredging the clogging of the goaf at the water inlet of the underground reservoir and reducing the salinity of the effluent, the carbon dioxide waste gas is input into the underground reservoir in a pulse mode and a continuous mode, so that the clogging area at the water inlet is dredged, the purification capacity of the underground reservoir on mine water is improved, and the salinity of the effluent of the reservoir is reduced. The system comprises: a carbon dioxide exhaust gas storage unit for providing carbon dioxide exhaust gas; the waste gas pulse conveying pipeline is connected between the carbon dioxide waste gas storage unit and the underground reservoir and used for conveying the carbon dioxide waste gas to the underground reservoir, and the gas outlet end of the waste gas pulse conveying pipeline extends into the underground reservoir and is located below the water inlet; and the pneumatic booster pump is connected with the waste gas pulse conveying pipeline and can output the carbon dioxide waste gas in the waste gas pulse conveying pipeline in a pulse manner.

Description

technical field [0001] The invention relates to the technical field of silting and dredging in goafs of water inlets of underground reservoirs. Background technique [0002] The underground reservoir water storage project is to store mine water in the underground goaf, and at the same time use coal pillar dam reinforcement and artificial dam construction to realize safe storage of mine water. Mine water protection and utilization are realized through system engineering such as reservoir design and construction, water pipeline network laying, and underground mine water treatment facilities. The roof in the underground reservoir will collapse to varying degrees, resulting in a large number of collapsed rocks in the reservoir. These rocks can purify mine water through water-rock coupling processes such as ion exchange, precipitation adsorption, redox, etc. when the mine water enters and exits the reservoir. , the process is economical and effective, and plays a very important ...
