Description
Technical field
The utility model belongs to the mine air-conditioning technical field, is a kind of high efficient heat exchanging air cooler that integrates the comprehensive mine cooling system of evaporative cooling, heat convection refrigeration and dustproof, scale removal.
Background technology
Along with the continuous intensification of the pit mining degree of depth, the problem occurred in mine is more and more, and wherein underground thermal pollution is one of most important factor of restriction mine safety.Underground thermal pollution mainly comprises high temperature rock heat, plant equipment heat radiation, oxidation heat production etc.The heat evil not only endangers the healthy of mine workman, reduces operating efficiency, serious threat mine safety especially.China's " safety regulations in coal mine " clear: " air themperature of mine main exploitation work plane must not be higher than 26 ° of C, and dynamo-electric chamber air themperature must not surpass 30 ° of C; When exploitation work plane air themperature surpasses 30 ° of C, when dynamo-electric chamber air themperature surpasses 34 ° of C, must stop operation "; " mine safety bar row " regulation: " air themperature of underground labour's operating location must not higher than 28 ° of C ".Hence one can see that lowers the temperature to mine is indispensable.
China is as world's producing coal the first big country, and within 2012, annual producing coal has reached 37.5 hundred million tons, but also needs 2.9 hundred million tons of imports, well imagines that the annual coal consumed of China is quite surprising.But China's pit mining condition is unsatisfactory, regulation, particularly underground thermal pollution that the production in many collieries does not reach country's formulation are the principal elements that causes mining environment not up to standard.Along with the utilization of continually developing of coal resources in China, deep mining is more and more general, but deep mining heat evil is just more serious, so underground thermal pollution becomes an obstacle of restriction deep-well exploitation, is one of urgent problem.
China's underground thermal pollution is administered and is started late, start from 20 century 70s, lived through the stage of theoretical research stage, the falling temperature technique trial stage in mid-term and the large-scale application since 21 century at initial stage, formed be widely used, the comprehensive mine of many means, extensive refrigeration administers situation.But, due to technical reason, the most mine cooling equipment of China depends on external import, causes very large economic pressures, to the long term growth of enterprise, be quite disadvantageous.Therefore, develop autonomous, economic, efficient mining temperature reduction equipment extremely urgent, also will greatly promote the development of coal in China industry.
Through research and development in recent years, the domestic mining temperature reduction equipment that has also occurred that several classes are new, but find by the research to these mining temperature reduction heat exchangers, exist following weak point: some heat exchanger only is comprised of a Heat Room, for non-dismountable formula, to transportation, installing and keeping in repair has adverse influence; Because mine Air dustiness is very large, Heat Room does not carry out pretreatment to the air that enters heat exchange, but directly and light pipe carry out interchange of heat, thereby increase the dedusting pressure of Heat Room, dust-proof effect is undesirable, without descaling function, after long-term the use, cause the coil pipe thermal resistance to increase, reduced the heat exchange efficiency of device; After the chilled water sprayed from shower and air carry out interchange of heat, water temperature is still lower, so this part chilled water is treated, can recycle, and avoids causing the waste of chilled water greatly later.
