s1, pretreatment of wet air: the wet air is filtered to remove dust through a filter window (31) and then pumped into an air compressor (32) for compression, so that the dew point of the wet air is reduced;
s2, condensing: the air compressor (32) conveys the compressed gas to the evaporator (4) for cooling, and saturated liquid water and liquid oil are separated out;
s3, measuring condensate: the total amount of condensate precipitated by the air compressor (32) flows into the water accumulation disc (51) and the water holding disc (52), and the liquid level gauge (53) detects the liquid height in the water accumulation disc (51) and feeds the liquid height back to the control module;
s4, outputting gas: judging the magnitude of precipitated dry gas according to the detected condensate height, matching the rotating speed level of a corresponding conveying fan (61), and conveying the condensate to the outside by the conveying fan (61);
s5, classifying condensate: after the liquid height of the condensate is detected, a first ball valve (54) is opened, the condensate is led into an oil separator (55), liquid oil in the condensate is separated into an oil storage tank (58), and liquid water is separated into a water tank (56) for storage;
s6, liquid oil post-treatment: the liquid oil in the oil storage tank (58) is filtered by the oil filter (59) and then is conveyed to a lubricating area of the vortex compressor (81) to serve as lubricating oil;
s7, liquid water post-treatment: after the liquid water in the water tank (56) reaches a certain amount, the liquid water is pumped to a cleaning pipeline (311) in the filter window (31) by a water pump (57) for cleaning dust accumulated on the filter window (31).
8. The method of claim 7, wherein the step of using the dehumidifying device of the freeze dryer comprises:
s3, high classification of condensate liquid is as follows: setting upThree orders of magnitude, the liquid height range detected by the liquid level meter (53) is set as 0~H, wherein +.>The corresponding liquid level meter (53) does not detect the condensate, namely the detected liquid height is always 0, no condensate exists in the water accumulation tray (51) in the state, and all condensate is in the water holding tray52 A low liquid fraction precipitated in the gas); />The detection range of the corresponding liquid level meter (53) is 0~H/2, namely, within half Gao Dufan of the detection range, in this state, the condensate in the water accumulation tray (51) is full, and the liquid in the overflow water tray (52) is within half of the liquid height, namely, the liquid precipitated in the gas accounts for a medium ratio; />The detection range of the corresponding liquid level meter (53) is H/2 or more, namely more than half Gao Dufan, in this state, the condensate in the water accumulation tray (51) is full, and the liquid overflow tray (52) is more than half of the liquid height, namely the liquid ratio of the precipitated liquid in the gas is high.
