Heat-radiating, recovering and cooling system for mine

Abstract

The invention discloses a heat-radiating, recovering and cooling system for a mine. The system comprises an enclosed cooling tower, a thermal energy recovering device, a thermal energy recovering device water circulating pump, a pressure exchanger, a pressure exchanger water circulating pump, a refrigerating and cooling device, a fan and an underground cooling unit water circulating pump, whereinall components adopt modular designs. The system integrates the advantages of centralized refrigeration and distributed refrigeration, so that a good underground cooling effect can be achieved. Meanwhile, a thermal energy recovery technology is adopted, so that all thermal energy produced by a refrigerator is recovered and utilized, the recovered thermal energy can be used for supplying hot waterfor bathing to the ground as well as heat in office areas in winter, and a boiler can be fully eliminated. A water treatment system of the system can be used for producing purified water or softened water by using waste water drained by a sewage treatment plant, and the produced water can be recycled by the system, so that the requirements for energy conservation and environmental protection are met.

Description

technical field [0001] The invention relates to a cooling system, in particular to a refrigeration cooling system applied to high-temperature workplaces such as coal mining and mining. Background technique [0002] Coal mines are one of the main energy sources in our country. With the development of society and the increasing development of coal resources, the mining depth of mines continues to increase. At present, the world's major coal mining countries have successively entered into deep mining, and the mining depth gradually increases, and the ground temperature also rises accordingly. The mining depth of some mines in Germany and Russia has reached 1400~1500m; the mining depth of the Carletonville gold mine in South Africa has reached 3800m, and the bottom of the shaft has reached 4146m below the surface; there are 30 mines over a kilometer in Canada and 11 in the United States. The average mining depth of my country's coal mines was 288m in 1980, and reached 428m in 1...
