The medical air cold dryer includes a pre-cooler, a pre-cooling temperature sensor, a gas-water separator, and two sets of heat exchange refrigeration systems; both sets of heat exchange refrigeration systems are equipped with inlet solenoid valves and outlet solenoid valves. A first solenoid valve is provided between the inlet pipeline of one set of heat exchange refrigeration system and the outlet pipeline of the second heat exchange refrigeration system, and the outlet pipeline of the first heat exchange refrigeration system and the outlet pipeline of the second heat exchange refrigeration system There is a second electromagnetic valve between the intake pipelines; the compressed air enters the gas-water separator from the air inlet through the pre-cooler, and through the control of the solenoid valve, the separated gas passes through the first set of heat exchange refrigeration system and At least one of the heat exchange refrigeration systems in the second heat exchange refrigeration system outputs air to the precooler, and finally discharges it from the air outlet. In the case of reducing the output pressure of the air compressor, there is no loss of regeneration air, which improves the safety and reliability of the system, saves energy, and meets the requirements for moisture in medical air.
Description
technical field [0001] The invention relates to the field of air cooling dryers, in particular to medical air cooling dryers. Background technique [0002] Medical air is the air used for medical purposes in medical and health institutions. Commonly used include medical air, instrument air and dental air. The requirements for moisture content are different. Medical air moisture content: ≤575mg / Nm 3 (equivalent to dew point -23.1°C), moisture content of air in equipment: ≤50mg / Nm 3 (equivalent to dew point -46°C), dental air moisture content: ≤780mg / Nm 3 (equivalent to dew point -20°C). The output pressure of commonly used air compressors is 0.7MPa~0.8MPa, and ordinary type cold dryers are used. Due to the constraints of the working principle, the condensation temperature cannot be lower than 2°C, generally 3°C~10°C, converted to normal pressure dew point at -15 ℃, which cannot meet the requirements of the above three kinds of medical air. With an adsorption dryer, the mo...
