Description
Technical field
The present invention relates to a kind of gas dehumidification drying device, more specifically, it relates to the cooling driers that a kind of heat exchange efficiency is high.
Background technology
Cooling driers is the abbreviation of freezing type drier, and it is the temperature utilizing refrigerating plant to reduce saturated compressed gas, separates out part water vapour, and separates discharge by moisture trap, thus reduce the dew point temperature of compressed gas, makes compressed gas be dried.The heat exchanger components of cooling driers is mainly precooler, vaporizer and condenser.Compressed gas is forced cooling in vaporizer, and therefore water vapour saturated in compressed gas condenses the water that is in a liquid state, moisture trap separate and discharge.Precooler Main Function is to reduce the heat exchange duty of vaporizer and then reducing refrigerant compression acc power, additionally assists in and improves the delivery temperature of compressed gas in case the pipeline of conveying compressed gas condenses.Condenser is that refrigeration system maintains the heat exchanger components run.At present, the major part precooler of cooling driers, vaporizer and condenser three are split type settings, and this adds a lot of external connection pipeline in the middle of invisible, pipeline more multiplex roles is the most, potential leak source is the most, easily causes the waste of energy, thus reduces heat exchange efficiency.And split type structure makes cooling driers overall structure huge, taking up an area space greatly, manufacturing cost is high.
