Research on the Application of Vortex Tube Type of Cooling Jacket in Coal Mine

摘要

The problem of heat damage in high temperature mine has been attached more and more concern to. In addition, the existing solutions also have problems which are large initial investment and poor safety performance. Vortex tube type of mine cooling jacket, studied in this paper, using vortex tube refrigeration principle. It used compressed exhaust gas as the gas source, which can solve the problem of the large-scale cooling equipment which rely on electricity, and may not emit toxic gases at the same time. Thereby, by using the method of observation and questionnaire survey, the parameters of the vortex tube were optimized for optimal cooling effect. In conclusion, the features of security, reliability, energy saving and environmental protection can be realized by the vortex tube type of cooling jacket. What's more important, we had investigated the feasibility of the application of vortex tube type of mine cooling jacket.
