Mine cooling system and method utilizing deep-well geothermal energy

Abstract

The invention discloses a mine cooling system utilizing deep-well geothermal energy. The mine cooling system comprises an air treatment system, a geothermal energy recovery system and an underground cold water system. The air treatment system comprises a travelling trolley and an air treatment device arranged above the travelling trolley. The air treatment device comprises an air inlet located in the end of the air treatment device and an air outlet located in the tail of the air treatment device, and a first-stage air cooler, a first-stage rotary dehumidifier, a second-stage air cooler, a second-stage rotary dehumidifier, a third-stage air cooler, a water baffle and a fan are arranged between the air inlet and the air outlet. The invention further discloses a mine cooling method adopting the system. The air treatment system and the geothermal energy recovery system are arranged, the rotary dehumidifiers are arranged in the air treatment system, the geothermal energy is taken form a heat recovery filling body to be used for dehumidification regeneration of the rotary dehumidifiers, energy consumption of the mine cooling system is reduced, the downhole dehumidification difficult problem is solved, and the comfort of the mine working face is improved.

Description

technical field [0001] The invention belongs to the technical field of mining of deep mineral resources, and in particular relates to a mine cooling system and method utilizing deep well geothermal heat. Background technique [0002] With the gradual reduction and depletion of shallow mineral resources, the development of deep mineral resources is a major demand for the country to ensure resource security and expand economic and social development space. For deep mining, heat damage phenomenon is particularly significant. [0003] In the deep well cooling system, the artificial cooling technology is mainly used. The cold source (ice flakes or cold water) is provided by the refrigeration unit, which is transported to the mining working face through a special cold delivery pipeline, and is exchanged with hot and humid air on the working face for cooling. For dehumidification and dehumidification, the commonly used air coolers are spray air coolers and surface air coolers. Th...

AI Technical Summary

Problems solved by technology

The dehumidification capacity of both the spray air cooler and the surface air cooler is limited, causing the air flow in the mine to be in a nearly saturated state. In addition, the medium used in the spray air cooler and the surface air cooler comes from a low-temperature refrigeration unit, causing mine machinery Refrigeration system consumes a lot of energy

Therefore, the existing mine cooling system has the problems of limited dehumidification capacity and high energy consumption
