[0002] The main function of the gas-liquid separator is to remove the liquid substances entrained in the gas. There are many types of gas-liquid separators. The traditional gas-liquid separator adopts the wire mesh mist separation method, which is more common. This type of gas-liquid separator is prone to salt crystal precipitation in the liquid substance after gas-liquid separation or heavy organic matter attached to the wire mesh, causing the wire mesh to be easily blocked, the gas-liquid separation efficiency is low, and the operation cycle is short.

[0003] In addition to low separation efficiency, if the wire filter is clogged, it will directly cause the gaseous material to be unable to be transported normally. The pressure on the transportation pipeline and equipment will cause the production system to stop, directly threatening the safety of personnel and the normal transportation of gas.

[0018] A water blocking disk 18 is fixedly and sealedly connected inside the upper sleeve 12, and an inner sleeve 9 concentric with the water blocking disk 18 is fixed at the lower end thereof, and an arc-shaped groove 10 is provided on the lower end surface of the water blocking disk 18 inside the inner sleeve 9, and the upper end of the inlet pipe 2 extends into the inner sleeve 9, and a gas-liquid channel is formed between the outer edge of the inlet pipe 2 and the inner edge of the inner sleeve 9, and a flow limiting cone 6 concentric with the inlet pipe 2 is fixed inside the upper end of the inlet pipe 2, and the flow limiting cone 6 is fixedly connected to the inlet pipe 2 through a plurality of fixing rods 7, and the plurality of fixing rods 7 are evenly arranged around the circumference, and a gap is provided between the outer edge of the lower end of the flow limiting cone 6 and the inner edge of the inlet pipe 2, and a plurality of outlet pipes 5 are evenly fixed on the circumference of the inlet pipe 2 part in the inner sleeve 9, and the outlet pipe 5 communicates with the inlet pipe 2 and the gas-liquid channel, and the gas outlet end of the outlet pipe 5 is inclined upward, and a spiral blade 8 is fixed on the outer edge of the inner sleeve 9.

[0019] A plurality of inclined grooves 11 are evenly distributed and fixed on the circumference of the water blocking disk 18 on the outer part of the inner sleeve 9, and the angle between the inclined grooves 11 and the axis of the water blocking disk 18 is 65 degrees. A plurality of vertical liquid retention belts are evenly distributed and fixed on the circumference of the inner wall of the upper sleeve 12 above the water blocking disk 18, and the liquid retention belt is composed of a plurality of quadrangular pyramidal protrusions 14 fixed on the inner wall of the upper sleeve 12, and a water guide groove 19 is formed between two adjacent liquid retention belts. A baffle cone ring 13 is fixed in the upper sleeve 12 above the liquid retention belt, and a wire filter 15 is fixed in the upper sleeve 12 above the baffle cone ring 13, and the wire filter 15 is a stainless steel wire filter.

[0020] When the high-pressure gas-liquid separator is working, the high-pressure gas-liquid mixture is input through the inlet pipe 2. Under the flow limiting effect of the flow limiting cone 6 at the upper end of the inlet pipe 2, part of the gas-liquid mixture is discharged through the upper end of the inlet pipe 2, and part of the gas-liquid mixture is discharged through the outlet pipe 5. The gas-liquid mixture discharged from the upper end of the inlet pipe 2 is deflected downward under the blocking effect of the arc-shaped groove 10 at the lower end of the water-blocking disk 18. At this time, the gas-liquid mixture deflected downward collides with the gas-liquid mixture discharged from the outlet pipe 5 to form a turbulent flow, so that the droplets in the gas-liquid mixture are accelerated to combine to form larger droplets, which then drip into the lower end cover 1 under the action of their gravity. The arc-shaped groove 10 can guide the gas-liquid mixture discharged from the upper end of the inlet pipe 2. The gas-liquid mixture that is deflected after contacting the arc groove 10 is guided to the inner wall of the inner sleeve 9, and the inner wall of the inner sleeve 9 becomes the carrier surface for the above-mentioned droplets to combine, thereby accelerating the speed of the droplet combination; then, the gas-liquid mixture from which part of the liquid is removed enters between the lower sleeve 3 and the inner sleeve 9. At the same time, under the guidance of the spiral blades 8, the gas-liquid mixture that enters between the lower sleeve 3 and the inner sleeve 9 rotates upward. Since the density of the droplets is greater than the density of the gas, under the action of centrifugal force, the droplets in the gas-liquid mixture between the lower sleeve 3 and the inner sleeve 9 will condense into large water droplets on the inner wall of the lower sleeve 3. Under the action of gravity, the droplets condensed on the inner wall of the lower sleeve 3 The large water droplets fall into the lower end cover 1; the gas-liquid mixture between the lower sleeve 3 and the inner sleeve 9 continues to ascend, and after the gas-liquid mixture hits the lower end surface of the water-blocking disk 18, part of the droplets in the gas-liquid mixture will gather and combine into large water droplets on the lower end surface of the water-blocking disk 18 and drip, and part of the gas-liquid mixture will enter the upper sleeve 12 above the water-blocking disk 18 through the chute 11. When the gas-liquid mixture flows through the chute 11, the droplets in the gas-liquid mixture will also combine on the inclined surface of the chute 11, and the water-blocking disk 18 and the chute 11 can further separate the gas and liquid; under the guiding effect of the chute 11, the gas-liquid mixture that enters the upper sleeve 12 above the water-blocking disk 18 through the chute 11 The object rotates upward, and under the action of centrifugal force, the droplets gather and combine on the inner wall of the upper sleeve 12. At the same time, under the interception effect of the liquid retention belt, the liquid retention belt can completely intercept the droplets on the outer side of the rotating gas-liquid mixture, and make the droplets combine in the water guide groove 19 and then flow downward; the rotating gas-liquid mixture hits the lower end surface of the baffle cone ring 13 after ascending, so that the droplets continue to combine on the lower end surface of the baffle cone ring 13 to form large water droplets and drip. At this time, most of the liquid in the gas-liquid mixture has been separated. After passing through the baffle cone ring 13, the gas-liquid mixture is filtered through the wire filter 15 and discharged through the air outlet pipe 17. The liquid accumulated in the lower end cover 1 can be discharged regularly.

[0021] The present invention has a simple structure, is easy to operate, has a high gas-liquid separation efficiency, and a long operating cycle. It can reduce the amount of liquid entering the wire filter 15 and can effectively avoid the problem of pipeline and equipment compression caused by clogging of the wire filter 15.

[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
