[0029] See also Figure 1-3 The utility model provides a technical solution: a gas-liquid separator for vacuum process, comprising:

[0030] The separator body 1 is a pressure vessel, wherein an air outlet pipe 2 is disposed at the top of the separator body 1, a liquid discharge pipe 3 is disposed at the bottom of the separator body 1, and a feed pipe 4 is disposed on the side wall of the separator body 1;

[0033] A flexible filter element 8, which is annular and is located below the first through holes 7. The flexible filter element 8 is sleeved on the enclosure 6 and abuts against the inner wall of the separator body 1;

[0034] The second guide member 9 is a conical rotating body shell, the outlet pipe 2 extends into the second guide member 9, the edge of the second guide member 9 is attached to and fixed on the inner top wall of the separator body 1, and the second guide member 9 is provided with a plurality of second through holes 10;

[0035] A filter element drainage mechanism 11, which is disposed above the flexible filter element 8 and abuts against the flexible filter element 8;

[0036] The aperture of the second through hole 10 is smaller than that of the first through hole 7, so as to ensure that the moisture in the atomized gas is filtered step by step;

[0037] The filter element drainage mechanism 11 includes a flat pressure ring 111 and two push rods 112. The flat pressure ring 111 is annular and abuts against the top of the flexible filter element 8. The two push rods 112 pass through the separator body 1 and are connected to the flat pressure ring 111. The flat pressure ring 111 is provided with a plurality of third through holes 12. Pressing the push rod 112 can cause the flat pressure ring 111 to press down the flexible filter element 8, squeeze out the water in the flexible filter element 8, and avoid the failure of the water filtering function after the flexible filter element 8 is saturated with water;

[0038] The separator body 1 is provided with two sealing sleeves 13, and the two push rods 112 are respectively slidably connected in the two sealing sleeves 13, so as to ensure the smooth sliding of the push rods 112 and the sealing of the connection between the separator body 1 and the push rods 112;

[0039] The flat pressure ring 111 is located below the first through holes 7 , so that the flat pressure ring 111 does not interfere with the gas-liquid separation function of the first through holes 7 .

[0040] Working principle: First, the gas containing moisture enters the separator body 1 from the feed pipe 4, and the heavier water droplets will fall and be discharged from the drain pipe 3. The light gas and the atomized gas pass through the flexible filter element 8 under the guiding action of the first guide member 5 and the enclosure 6. The flexible filter element 8 absorbs and filters the moisture in the atomized gas. Secondly, the filtered atomized gas passes through the third through hole 12 and enters the enclosure 6 from the first through hole 7 to complete the first-level separation. Then, the second through hole 10 enters the second guide member 9 to complete the second-level separation. The moisture in the atomized gas after filtration and two-stage separation is completely separated, and the gas is discharged from the outlet pipe 2, so that the dehumidification and filtration effect of the gas-liquid separator is good. Finally, when the gas-liquid separator has been running for a period of time, pressing the push rod 112 can act on the flat pressure ring 111 to press down the flexible filter element 8, squeeze out the moisture in the flexible filter element 8, and avoid the failure of the moisture filtration function after the flexible filter element 8 is saturated with water.
