Described water knockout drum adds circumference type deflection plate after cyclone plate.Allow the air rotated fully contact on round deflection plate inside and outside circle, the moisture not only having prevented the generation of eddy current but also effectively tackled, thus improve a point water efficiency.
Described fluid reservoir is arranged water level display meter, and dirty valve is put in setting in the bottom of described fluid reservoir.
Cooler blower fan is set in described cooler.
In described condenser, condenser fan is set.
Cut-in pressure controller between the pipeline of described cold medium compressor upper left quarter access evaporimeter and the outlet copper pipe mouth of condenser.
The pipeline that the right lower quadrant of described cold medium compressor is connected with by-passing valve arranges refrigerant Pressure gauge, the pipeline that the upper left quarter of described cold medium compressor is connected with evaporimeter arranges refrigerant Pressure gauge.
Described cooling driers, first the high temperature compressed air entering cooling driers enters upright U-shaped heat exchanger, allows the highest entrance high temperature compressed air exchange with the minimum compressed air after evaporimeter is cold by force.So not only make the temperature entering evaporimeter more reduce, stabilize pressure leak source, but also improve export gas quality.The frame mode that described cooling driers superposes from bottom to up, the compressed air entered is made to be arrive water knockout drum draining from top to bottom, process cool configuration structure closely without any position ponding, compressed air is gone downstream, meet moisture content downward from gravity, finally automatically discharge moisture through water knockout drum again, the moisture of discharging flows into fluid reservoir by piping filter, non-environmental-pollution, the compressed air of discharging after moisture flows out from bottom to up in the U-shaped interchanger copper pipe of over-heat-exchanger again.
The workflow of described cooling driers is: compressed air (about 80 DEG C) enters the copper pipe outer wall of heat exchanger through entrance, enter cooler again and be cooled to about about 40 DEG C, enter evaporimeter again by pressure-air cooling to less than 10 DEG C, enter water knockout drum again, fluid reservoir is entered by piping filter, enter in heat-exchanger brass pipe, the hot-air with copper pipe outside carries out heat exchange again, finally discharges from outlet.
Beneficial effect of the present invention is:
Improve the service efficiency of heat exchanger, increase cooling driers compressed air output temperature, avoid the outer ponding of efferent duct; Improve the service efficiency of cooler, make the moisture of cooler flow into base of evaporator smoothly to discharge; The moisture that water knockout drum of the present invention is effectively tackled, thus improve a point water efficiency.Whole invention improves the service efficiency that cooling driers respectively configures, can when more severe the pressure leak source of stable output, arrange piping filter and fluid reservoir can filter sewage simultaneously, environment friendly and pollution-free.
