The freezing type compressed air dryer adopts the working principle of temperature reduction and condensation and mainly comprises a heat exchange system, a refrigerating system and an electric control system. The compressed air firstly enters the cooler to carry out air-air or air-water heat exchange to remove a part of heat energy, and then enters the cold and hot air exchanger to carry out heat exchange with the cold air which is cooled to the pressure dew point from the evaporator, so that the temperature of the compressed air is further reduced. Then the compressed air enters an evaporator to exchange heat with the refrigerant, the temperature of the compressed air is reduced to 0-8 ℃, moisture in the air is separated out at the temperature, and the air is separated by a gas-water separator and then discharged by an automatic drainer. And the dry low-temperature air enters the cold-hot air exchanger for heat exchange, and is output after the temperature is increased.
In the existing dryer, compressed air in a gas-liquid separator normally enters a tank body directly through an air inlet pipe, the compressed air enters the tank body and then settles downwards only by gravity, and downward liquid is attached to the inner wall surface and gathered together and finally discharged through a water discharge pipe. The gas-liquid separator has poor gas-liquid separation effect, and water gathered at the bottom of the tank body is easily brought into the air outlet pipeline by the rising compressed air, so that the gas-liquid separation effect is reduced.
Although the refrigerating type compressed air dryer disclosed in CN208943772U solves the above problems, it has the following disadvantages, such as: the separation effect is poor due to the short path and the short path time of the gas in the box body.
