The air inlet of the cyclone-type steam-water separator is positioned on the side surface of the cylinder wall, airflow rotates along the cylinder wall after entering the cyclone-type steam-water separator, and steam-water separation is realized by means of centrifugal force. The principle of the baffle type steam-water separator is that gas entering the device is guided to pass through a set baffle region, so that the gas flow continuously collides with the baffle to realize steam-water separation. The baffle guides the gas to the bottom of the cylinder body, and the gas flow impact is large due to the adoption of right-angle steering; the area is small as a steam-water buffer area, so that part of gas is mixed in liquid and is discharged by the filtrate pump, and meanwhile, the liquid containing air bubbles can cause the cavitation phenomenon of the pump when being discharged by the filtrate pump, so that the service life of the filtrate pump is shortened. In the process of forming rotational flow, the cyclone-type steam-water separator and the baffle-type steam-water separator have large energy loss, so that the load of the vacuum pump is increased, and the efficiency is reduced.
The principle of the gravity type steam-water separator is that the gravity of gas and floating liquid drops is different to generate a settling effect, the steam-water separator is suitable for steam-water separation operation with the liquid drop diameter larger than 200 mu m, and for a vacuum dehydration process, water cannot be well separated, so that the production efficiency and the normal operation of equipment are seriously influenced.

A water outlet 13 is arranged at the bottom of the cylinder 1, and the filtrate pump 2 is communicated with the water outlet 13 and used for discharging the liquid after steam-water separation out of the cylinder 1; the inclined baffle 4 is positioned at the bottom of the barrel 1, and the inclined direction of the inclined baffle is arranged towards the water outlet 13, so that sufficient liquid drainage is ensured, and meanwhile, the cleaning and maintenance of the steam-water separator at the later stage are facilitated.
Specifically, an annular flow space is formed between the vertical baffle 3 and the cylinder 1, and the mixed gas enters through the gas inlet 11 and then flows rotationally along the annular flow space. A plurality of V-shaped flow deflectors 5 are arranged on at least one of the inner wall of the cylinder body 1 and the inner wall and the outer wall of the vertical baffle 3 and are used for dividing the main air flow close to each wall surface into a plurality of strands of small air flows, so that steam-water separation is realized.
