Abstract

A new energy air-conditioning system for freeze protection of a well head and freeze protection of a surface for a mine, comprising a natural energy source collecting sub-system, an energy converting sub-system and a freeze protection end sub-system. The natural energy source collecting sub-system can absorb low grade natural energy sources of mine drainage, mine return air and solar energy which are converted to grade required for freeze protection of the well head and freeze protection of the surface for the mine by an energy source converting air conditioning device that consumes a little power or high grade energy sources such as high temperature heat energy and transported to a freeze protection end device by a heat-carrying agent to meet the requirements of freeze protection of the well head and freeze protection of the surface for the mine. The utility model overcomes the deficiencies of high energy consumption, high pollution and high operation cost by adopting a large amount of fuel for freeze protection originally. Compared with conventional ground source heat pump freeze protection system, the system device is simpler and more reliable, saves more on initial investment and occupied space and reduces the operation cost by more than 60% so as to realize brand-new new energy source air conditioning solution to solve the freeze protection problem by natural energy sources.

A kind ofly be used for the new forms of energy air-conditioning system that the mine well head is antifreeze and the face of land is antifreeze

Technical field

The utility model relates to a kind of new forms of energy air-conditioning system that the mine well head is antifreeze and the face of land is antifreeze that is used for, and belongs to the mine field of energy-saving technology.

Background technology

At present the method that adopts usually of the antifreeze problem of well head in winter of extractive industry such as colliery is: sent in the pit shaft by coal-fired, fuel oil or gas fired-boiler heating clamber external air inlet temperature to 2～5 ℃ again, occur dangerous when causing personnel, equipment transportation to avoid well head to freeze.But this method needs labor fuel, has the shortcoming of high energy consumption, high pollution, high operating cost.In addition, coal corridor, last storehouse etc. is located also to have high energy consumption and operating cost problem because heating on duty (about 5～10 ℃ usually) need be set.

For this reason; At present occurred adopting mode such as earth source heat pump to carry out the antifreeze way of well head; Carry out waste heat recovery than the high-grade energy in particularly that temperature levels is higher mine drainage or the mine return air; And transfer in the air that gets into mine by heat pump, can keep higher Energy Efficiency Ratio, therefore can effectively reduce the pollution problem and the operating cost of Boiler heating.

But, adopt the system of earth source heat pump usually because the actual motion Energy Efficiency Ratio of whole therrmodynamic system is often lower, and power consumption is also bigger, thereby the actual motion expense is often still higher, and initial cost is bigger, has influence on the economic benefit in colliery.

Summary of the invention

The purpose and the task of the utility model are; To the problems referred to above that exist; Develop a kind of new forms of energy air-conditioning system that the mine well head is antifreeze and the face of land is antifreeze that is used for; Adopt mine drainage or natural energy resource such as mine return air or solar energy as main energy sources, be aided with small amount of electrical energy, bear the antifreeze energy consumption of well head comprehensively and reach the antifreeze demands in the face of land such as going up coal corridor, storehouse.
