Embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1 and 2, an embodiment of the present utility model provides a gas-liquid separator, including: the separator comprises a separator body 1, a pressure transmitter 2, a filter cartridge 3 and a valve 4; the inside of separator body 1 is separation cavity 11, be equipped with on the top lateral wall of separator body 1 with gas outlet 12 and the air inlet 13 of separation cavity 11 intercommunication, the top one end of separation cavity 11 is loudspeaker form 14, and its big one end of diameter is kept away from air inlet 13 sets up, its small one end of diameter with air inlet 13 is tangent, the bottom of separator body 1 is equipped with liquid outlet 15. The pressure transmitter 2 communicates with said air inlet 13. The filter cartridge 3 is installed in the separation chamber 11, and the air inlet end of the air outlet 12 is communicated with the air outlet end of the filter cartridge 3. A valve 4 is mounted at said liquid outlet 15.

When the gas-liquid mixing medium is used, the gas-liquid mixing medium enters the separation chamber 11 through the gas inlet 13 to be separated, the pressure of the gas-liquid entering the separation chamber 11 is improved through the pressure transmitter 2 when the gas-liquid mixing medium enters, meanwhile, one end of the top of the separation chamber 11 is in a horn shape 14, and the small-diameter end of the separation chamber is tangent to the gas inlet 13. When the gas-liquid mixed medium enters the separation chamber 11 through the air inlet 13, the horn-shaped 14 structure can ensure that the gas-liquid mixed medium enters the separation chamber 11 and then makes centrifugal movement, the gas-liquid mixed medium flows downwards along the inner wall of the separation chamber 11 of the separator body 1 after entering, and in the downward movement process, the flow velocity of the gas-liquid mixed medium is gradually reduced, so that tiny liquid drops are converged into large liquid drops, and the gas-liquid separation effect is improved. The liquid falls into the bottom of the separation chamber 11 due to gravity, and when the liquid is collected in a certain amount in the separation chamber 11, the valve 4 arranged at the liquid outlet 15 at the bottom of the separator body 1 is opened to be discharged. The separated gas enters the filter cartridge 3 for secondary separation, and the gas after secondary separation is discharged through the gas outlet 12 communicated with the filter cartridge 3.

In another embodiment, as shown in fig. 1, the separator body 1 includes: the upper cylinder cover 16, the cylinder body 17 and the lower cylinder cover 18, and the air inlet 13 and the air outlet 12 are oppositely arranged on the side wall of the upper cylinder cover 16; one end of the cylinder block 17 is connected to the bottom of the upper cylinder head 16. A lower cylinder head 18 is connected to the other end of the cylinder block 17, and the liquid outlet 15 is provided on the lower cylinder head 18. When the upper cylinder cover 16 and the lower cylinder cover 18 are connected with the cylinder body 17, the separation chamber 11 is formed at the middle part of the upper cylinder cover 16, and the inner side wall of the upper cylinder cover 16 is in a horn shape 14.

The separator body 1 is provided in three parts for convenient maintenance and replacement of the filter cartridge 3. Because the air inlet 13 is arranged on the upper cylinder cover 16, the horn-shaped 14 is also arranged on the upper cylinder cover 16, so that the gas-liquid mixed medium entering through the air inlet 13 can perform centrifugal motion in the separation chamber 11 to form rotational flow, and the rotational flow is diffused to the inner side wall of the cylinder body 17. The separated liquid is discharged at regular intervals through a liquid outlet 15 provided in the lower cylinder head 18.

In another embodiment, as shown in fig. 1, the air inlet 13 is disposed lower than the air outlet 12. Because the density of the gas-liquid mixture medium and the density of the separated gas are different, the height of the gas inlet 13 is lower than that of the gas outlet 12, and the unfiltered gas-liquid mixture medium is prevented from being directly discharged.

In another embodiment, as shown in fig. 1 and 2, the upper cylinder cover 16 is provided with a liquid level meter 5, and a detection end of the liquid level meter 5 extends into the separation chamber 11. The liquid level meter 5 is arranged on the upper cylinder cover 16, the detection end of the liquid level meter 5 stretches into the separation chamber 11, separated liquid is measured, and the phenomenon that the liquid enters the filter cartridge 3 due to the fact that the liquid level of the liquid is too high is avoided.

In another embodiment, in order to facilitate the timing and automatic starting of the valve 4 for draining, the valve 4 is an electromagnetic valve, and the gas-liquid separator further comprises a controller (not shown in the figure), wherein a signal input end of the controller is connected with a signal output end of the liquid level meter 5, and a signal output end of the controller is connected with a signal input end of the electromagnetic valve.

The controller is arranged to feed back a signal to the controller when the liquid level meter 5 detects that the separated liquid level reaches a preset maximum value, and the controller controls the electromagnetic valve to be opened so as to discharge the liquid in the separator body 1. Avoiding liquid entering the air outlet 12 through the filter cartridge 3, resulting in a gas exiting the air outlet 12 containing a significant amount of moisture.

In another embodiment, as shown in fig. 1, in order to further avoid liquid entering the filter cartridge 3, the sensing end of the level gauge 5 is mounted at a lower level than the filter cartridge 3 when the level gauge 5 is mounted.

Specific working principle:

when in use: the gas-liquid mixed medium enters the horn-shaped 14 part of the separation chamber 11 along the tangential direction of the air inlet 13, and centrifugally moves in the horn-shaped 14 inner cavity of the upper cylinder cover 16 to form a rotational flow which is diffused into the cylinder body 17, and the rotational flow can generate centrifugal force which is many times higher than gravity, so that the centrifugal force is greatly different due to the different densities of the gas-liquid two-phase medium. Under the action of centrifugal force, the lighter gas phase moves towards the middle to form upward internal rotation flow; the heavier liquid phase is thrown to the side wall to form downward outer swirl flow, so that the separation of gas and liquid phases is realized. The gas after centrifugal separation is subjected to secondary separation by the filter cartridge 3, and the gas after secondary separation is discharged from the gas outlet 12. The separated liquid is temporarily stored in the cylinder 17, and when the liquid level in the cylinder 17 reaches the set height of the liquid level meter 5, the liquid is discharged from the electromagnetic valve connected with the lower cylinder cover 18.

Finally, it should be noted that: the foregoing description is only a preferred embodiment of the present utility model, and the present utility model is not limited thereto, but it is to be understood that modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art, although the present utility model has been described in detail with reference to the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
