| description | The utility model discloses a heat exchange device for underground coal mine membrane separation nitrogen making equipment, which comprises a spiral plate heat exchanger, a hot air inlet, a hot air outlet, a cold air inlet and a cold air outlet, a communicating pipe is fixedly mounted between a cold air inlet pipe and a cold air outlet pipe, a cold valve is mounted on the communicating pipe, and a hot valve is mounted on the cold air outlet pipe. The spiral plate type heat exchanger does not need an external power source, heat generated by an external air compressor is used as a heat source, the cooled compressed air is subjected to heat exchange and temperature rise, energy consumption is greatly reduced in the whole process, and energy conservation and environmental protection are achieved; the temperature of the gas flowing out of the spiral plate type heat exchanger is accurately adjusted while the flow and the flow speed of the gas are kept unchanged, it is guaranteed that the temperature of the gas is a |
