The invention discloses a
compressed air drying device based on a vortex tube
refrigeration technology, belonging to the technical field of
air drying. The
compressed air drying device comprises an
air compressor, an air-liquid
heat exchanger, an air cooler, a high-pressure air
storage tank, a high-pressure dehumidifier, a first control valve, a
nozzle, a pore plate, a vortex tube, a second control valve, a high-pressure
liquid storage tank, a first throttling valve, an
intermediate heat exchanger, a solution heater, a normal-pressure regenerator, a normal-pressure
liquid storage tank, a high-
pressure solution pump, a solution cooler, a third control valve and a dry air outlet. The invention further discloses a working method of the
drying device. The drying device has the following beneficial effects of improving the energy utilization efficiency of the
compressed air drying
system, enhancing humidifying and regenerating effects, effectively reducing the
moisture content of a compressed air outlet, and improving the refrigerating efficiency and the energy
utilization rate of the vortex tube. The working method of the compressed
air drying device based on the vortex tube regeneration technology is simple in steps and is energy-saving and environment-friendly.
