The lower end of the inner sleeve body 11 of the gas-liquid separator and the bottom end of the separator body 4 have preset intervals, so that the interval between the liquid level of separated liquid and the lower end of the inner sleeve body 11 is not less than 150mm, and the possibility of mixing gas and separated liquid is avoided.

In order to fully liquefy the gaseous water in the gas-liquid mixed medium, the gas-liquid mixed medium inlet 3 is higher than the cold medium outlet 13, and the lower end of the inner sleeve body 11 is lower than the cold medium inlet 10, so that the cold medium is prevented from entering the second gas-liquid channel 16.

When the gas-liquid separator is used, a high-temperature gas-liquid mixed medium enters the first gas-liquid channel 5 from top to bottom through the gas-liquid mixed medium inlet 3, the gas-liquid mixed medium exchanges heat with cold medium flowing from bottom to top in the spiral coil 12 of the cold medium (20-40 ℃ and normal temperature air or circulating water in general), the cooled gas-liquid mixed medium enters the second gas-liquid channel 16 from top to bottom in the annular gap 5 of the separator, during the flowing process, gaseous water in the cooled gas-liquid mixed medium is gradually transformed into liquid by touching the inner wall of the inner sleeve body 11, the liquid water falls into the bottom of the gas-liquid separator along the inner wall of the inner sleeve body 11 under the action of gravity of the liquid water, after the liquefied liquid is collected to a certain amount in the bottom of the gas-liquid separator, the drainage valve 8 arranged on the drainage outlet 9 at the bottom of the separator body 4 is opened, and the separated liquid can be discharged through the drainage outlet 9.

The inner sleeve body 11 is of a cylindrical structure with an unsealed lower end, and the top end of the inner sleeve body is in a closed state, so that the inner sleeve body is beneficial to dripping after the gaseous water is liquefied; the top cover 1 is a flat cover or an elliptic or other structural form; the bottom seal head 7 of the gas-liquid separator is of an elliptical seal head structure and can be better attached to the separator body 4.

In another embodiment, the inner sleeve body 11 is movably accommodated within the separator body 4.

In order to realize the movable accommodation of the inner sleeve body 11, as shown in fig. 2, the inner wall of the separator body 4 is provided with a first clamping piece 2; the outer wall of the inner sleeve body 11 is provided with a second clamping piece 14; the first clamping piece 2 is clamped on the second clamping piece 14, so that the separator body 4 is connected with the inner sleeve body 11 for positioning, and the annular gap 5 is formed.

More specifically, the first clamping member 2 is concave; the second clamping member 14 is convex; the number of the first clamping pieces 2 is the same as the number of the second clamping pieces 14; the concave depth and shape of the first clamping piece 2 correspond to the convex height and shape of the second clamping piece 14.

When the inner sleeve body 11 is used, the first clamping piece 2 and the second clamping piece 14 can be clamped or scratched according to the requirements, and when the first clamping piece 2 and the second clamping piece 14 are scratched, the inner sleeve body 11 can be taken out from the separator body 4.

In another embodiment, as shown in fig. 1, in order to enable the separated liquid to be discharged in time, a liquid level sensor 6 is further provided on the body 4.

More specifically, the installation height of the sensing end of the liquid level sensor 6 is lower than the installation height of the inner sleeve body 11, and the distance from the lower end of the inner sleeve body 11 is 50-100 mm, so that the liquefied liquid and the liquefied gas are prevented from being mixed again.

In order to cooperate with the liquid level sensor 6 to improve the liquid discharge efficiency, the drain valve is an electromagnetic valve, and the signal output end of the liquid level sensor 6 is connected with the signal input end of the drain valve 8.

When the liquid level collected at the bottom of the gas-liquid separator exceeds a set value in use, the liquid level sensor 6 senses and transmits a signal to the drainage valve 8, the drainage valve 8 receives the signal and opens a valve switch, and liquid is discharged from the drainage outlet 9.

In another embodiment, as shown in fig. 1, to further enhance the gas-liquid separation effect, the gas-liquid separator further includes a demister 15, where the demister 15 is located in a space in which the inner sleeve body 11 extends downward from the top end thereof by a preset distance, and can perform secondary separation on the gas-liquid mixed medium; specifically, the demister 15 is located at the end of the second gas-liquid channel 16 and communicates with the gas outlet 17.

When the gas-liquid separator is used, the mixed medium which has completed the gas-liquid separation of the first step passes through the demister 15 to complete the gas-liquid separation of the second time, the separated liquefied water vapor is collected on the surface of the demister 15, when small liquid drops are collected into large liquid drops, the liquid drops to the bottom of the gas-liquid separator under the action of gravity of the liquid drops, and the mixed medium after the gas-liquid separation of the second time is discharged out of the gas-liquid separator body 4 through the gas outlet 17.
