Problems solved by technology
[0002] For the utilization of waste heat from mine exhaust air, the original technology has two different technical routes. One is spray heat extraction. Spray heat extraction has the defects of water blockage and small heat extraction. The exhaust air cannot be used below 12°C. The second is direct steam heat extraction. Although direct steam heat extraction has a large amount of heat, there is a problem that the exhaust air heat exchanger is easily blocked during operation due to the fact that there is a lot of dust in the exhaust air. The wind resistance of the exhaust air heat exchanger is relatively large
In addition, in order to eliminate the 30-40dB(A) noise of the mine return air main engine, the existing exhaust air heating device is equipped with a muffler, which will further increase the wind resistance and lead to an increase in energy consumption

Embodiment Construction
[0013] see figure 1 , the mine exhaust air and waste heat hybrid heat extraction heat pump system of the present invention includes a exhaust air heat exchange chamber 5, and an exhaust air passage 32 is provided in the exhaust air heat exchange chamber 5, and the lower part of the exhaust air passage 32 is A sump 9 with an open top for collecting the water sprayed from above is provided. A spray pipe network 6 is installed directly above the sump 9, and a plurality of downward spraying pipes are installed on the spray pipe network 6. When the sprayed water passes through the exhaust air channel 32, it will exchange heat with the exhaust air, thereby extracting the heat energy in the exhaust air, and bringing the extracted heat energy into the sump 9, spraying the pipe network The water inlet of 6 communicates with the sump 9 through the spray water intake pipe 8 connected in series with the circulation spray pump 7, and the circulation spray pump 7 can continuously transport ...

A coal mine ventilation air waste heat mixed type heat-obtaining heat pump system comprises a ventilation air heat-exchange chamber, wherein a ventilation air channel is installed in the ventilation air heat-exchange chamber, a water collecting pool with the open top is installed under the ventilation air channel, a spraying pipe network is installed right above the water collecting pool, a water inlet of the spraying pipe network is communicated with the water collecting pool through a spraying water-obtaining pipe in series connection with a circulating spraying pump, an air inlet of the ventilation air channel is communicated with an outlet of a mine return air main channel through an air channel, and a direct evaporation type ventilation air heat exchanger is installed in the ventilation air channel located on the rear side of the water collecting pool. An air outlet of the ventilation air channel is communicated with the outside, an outlet of a heat-exchange pipe of the ventilation air heat exchanger is communicated with one connecting pipe opening of a right four-way valve through a delivery pipe, and an inlet of the heat-exchange pipe of the ventilation air heat exchanger is communicated with a heat-exchange pipe of a right casing pipe hydraulic filling type condensation evaporator. The coal mine ventilation air waste heat mixed type heat-obtaining heat pump system is small in operation air resistance, low in energy consumption, high in heat efficiency and capable of saving a large amount of energy and reducing environmental pollution.
Description
technical field [0001] The invention relates to a mixed type heat extraction heat pump system for exhaust air and waste heat in a mine. Background technique [0002] For the utilization of waste heat from exhaust air in mines, the original technology has two different technical routes. One is spray heat extraction. Spray heat extraction has the defects of water blockage and small heat gain. The exhaust air cannot be used below 12°C. The second is direct steam heat extraction. Although direct steam heat extraction has a large amount of heat, due to the fact that there is a lot of dust mixed in the exhaust air, there is a problem that the exhaust air heat exchanger is easily blocked during operation, resulting in The wind resistance of the exhaust air heat exchanger is relatively large. In addition, in order to eliminate the 30-40dB(A) noise of the mine return air main engine, the existing exhaust air heating device is equipped with a muffler, which will further increase the ...
