A kind of freezing type drier moisture trap
Technical field
Freezing type drier technical field is the utility model is related to, more particularly to a kind of freezing type drier gas
Separator.
Background technology
Freezing type drier has used physical principle, and the moisture in compressed air is refrigerated to below dew point, is allowed to from sky
The dried-air drier separated out in gas, the source of the gas treatment element belonged in pneumatic system.Freezing type drier generally include compressor,
Condenser, choke valve, evaporator and moisture trap.At present, common moisture trap include baffle-type moisture trap and
Cyclone type gas-water separator, baffle-type moisture trap is simple in construction, and manufacture is simple, and still, its gas-water separation effect is not as rotation
The separating effect of wind formula moisture trap.
Existing baffle-type moisture trap and cyclone type gas-water separator can meet that the gas-water separation under general operating mode will
Ask, still, the operating mode higher to gas-water separation effect requirements, especially there is the work that higher position reason requires to the less drop of diameter
Condition, its separating effect is not satisfactory, can not remove the liquid foam being mingled with gas.If also continue to use existing baffle-type gas
Separator or cyclone type gas-water separator, excessive moisture will be brought to downstream process link by air-flow, cause in downstream links
Require that degree of drying high humidity of media is excessive and even produce failure, it is necessary to frequently change the medium, larger safety be present
Hidden danger.Meanwhile in baffle-type moisture trap, it is aobvious that baffle plate easily make it that the compressed gas flow velocity into moisture trap declines
Write, not only slow down compressed gas processing speed, largely influence moisture trap efficiency, and moisture trap is caused
Greater impact, fragile moisture trap.
