[0033] Working principle:

[0034] In the first step, industrial steam enters the steam-water mixing device 5 from the steam supply module, and at the same time, condensed water enters the steam-water mixing device 5 from the water supply system of the water supply module. The industrial steam and condensed water are mixed and enter the mixing adjustment module.

[0035] In the second step, it rises along the central tube to the top of the main tower and is discharged from the main tower outlet. The spiral separator will drive the steam to rotate and descend inside the main tower, so that large droplets with large inertial centrifugal force are thrown to the side wall of the main tower and separated from the steam. The separated droplets descend along the side wall of the main tower and are discharged from the main tower drain port. The steam entering the auxiliary tower rises upward in a curve from the outside of the circular baffle and the middle of the annular baffle in turn. The water droplets will accumulate on the circular baffle, and the steam will be separated from water for a second time. The separated steam will then pass through the sintering filter assembly to further filter the water and impurities in the steam, so as to obtain steam that meets the requirements of dryness and cleanliness.
