In gas.
In practical work process, in step 2, the gas in air enters absorption bottle, and gas is by the absorption bottle
After absorbing liquid absorbs, enters the condenser from the absorption bottle, be actually into the gas of the condenser at this time
Carry the fluid mixture of the gentle body of steam secretly, if suck-back phenomenon has occurred, the resistance piece cooperate the differential pressure pick-up and
First control system can shut down the body pump work, and when there is no suck-back phenomenon, sampling air flow still can be entrained with
Steam in the mixture of steam, i.e., the described aqueous vapor and gas can be condensed into liquid in the condenser, accumulate in described cold
The bottom of condenser, and gas then comes back in air through the air pump, when the liquid level sensor is detected when the condensation
When the liquid of device bottom accumulates to certain altitude, second control system then controls wriggling pump work, will be in the condenser
Liquid take away.
The above disclosure is only a preferred embodiment of the invention, cannot limit the right of the present invention with this certainly
Range, therefore according to equivalent variations made by scope of the present invention patent, it is still within the scope of the present invention.
