The Application of Vortex Tube in Deep Mine Cooling

With the development of mining economy and the exploitation of mining technology, deep well mining has become a trend. The technical requirements of mine thermal environment are getting higher and higher. It can not effectively solve the problem of mining high-temperature by using the general cooling ways. With general ways, the system needs to consume a large amount of energy. At the same time by using of freon refrigerant, it will emit a lot of greenhouse gases. All of these are not in conformity with the relationship between the requirements of sustainable development and the vital interests of human development. In this paper, the program of vortex tube cooling in deep well has been advanced. Vortex tube has advantages of simple structure, no moving parts, working stability and has a wide-range working scope. It has been applied in some respects. It has a large cooling speed and does not use the freon refrigerant. This paper conducted a feasibility analysis of vortex tube cooling, proved that vortex tube cooling in deep well meet the cooling needs, has a better economic efficiency at the same time has highly energy and environmental benefits. Vortex tube cooling in deep well realizes the energy-saving and emission reduction in the true sense.
