Working principle

• Compressed air first enters the precooler (20 or 21)for preliminary cooling,Then it flows into the regenerator (1) and undergoes heat exchange with the returned product gas, resulting in compression.The air further cools down. And discharge the condensed water outside the machine Afterwards, press The compressed air flows into the evaporator (2) and exchanges heat with the refrigerant, causing the compressed air to Further cooling to achieve the required dew point temperature.
• Compressed air passes through the precooler (21 or 20),
regenerator (1), and evaporator(2) After gradual cooling, the water vapor in the air condenses into liquid droplets, passing through the gas liquid The function of separator (3) is to separate liquid water.
• The dry cooling air passing through the separator (3) of the enterprise passes through the regenerator(1) Another process, which is heated up when leaving the dryer, reduces the air flow Relative humidity.
