Description

Technical Field

[0001] This utility model relates to the field of liquid-gas separation technology, and in particular to a liquid-gas separation device for a control system. Background Technology

[0002] A liquid-gas separator for control systems is a device used to separate liquid and gas mixtures. Liquid-gas mixing is involved in many industrial control systems and processes, such as in petrochemicals, natural gas processing, pharmaceuticals, and some advanced manufacturing fields.

[0003] In many control systems, liquid-gas separation devices are installed on vacuum pumps to save water. For example, the 2VB series vacuum pump is equipped with a liquid-gas separation device when it is connected to a 15° circulating water system with a portion of the coolant. This liquid-gas separation device mainly consists of a metal tank, an inlet pipe, an outlet pipe, and an exhaust pipe. It mainly uses gravity settling to separate liquid and gas. The gas is discharged from the outlet pipe upwards, and the liquid falls to the bottom of the tank. However, for some tiny droplets, gravity settling alone may not be enough. When the gas and liquid mixture enters the tank, the liquid sinks under the action of gravity, but some tiny droplets may rise with the gas, resulting in the waste of some liquid. To solve the above problem, we propose this liquid-gas separation device for control systems. Utility Model Content

[0004] The main objective of this invention is to provide a liquid-gas separation device for a control system, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A liquid-gas separation device for a control system includes a lower separation tank and an upper separation tank. The lower separation tank is provided with an inlet pipe, an outlet pipe, and a drain pipe communicating with its interior. The upper separation tank is provided with an outlet pipe communicating with its interior. The upper separation tank is provided with multiple interception mechanisms for intercepting tiny liquid droplets. Each interception mechanism includes multiple mounting rods fixedly connected to the inner wall of the upper separation tank. A perforated plate is provided on all of the mounting rods. The lower separation tank is provided with a cleaning mechanism for cleaning the perforated plate.

[0007] Preferably, the cleaning mechanism includes multiple support rods fixedly connected to the inner wall of the separation tank, a drive housing fixedly connected to the multiple support rods, a drive motor fixedly connected to the bottom of the drive housing, a drive shaft fixedly connected to the output shaft of the drive motor, and multiple brush plates fixedly connected to the side wall of the drive shaft.

[0008] Preferably, the multiple support rods are arranged at equal intervals, and the upper end of the drive housing is provided with an inclined surface.

[0009] Preferably, the side wall of the separating tank is provided with a water injection pipe, a water outlet ring is connected to the water injection pipe, and multiple nozzles are connected to the water outlet ring below.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1-4 As shown, a liquid-gas separation device for a control system includes a lower separation tank 1 and an upper separation tank 3. The lower separation tank 1 is provided with an inlet pipe 2, an outlet pipe 4, and a drain pipe 5 communicating with its interior. Valves are provided on the inlet pipe 2, the outlet pipe 4, and the drain pipe 5. The upper separation tank 3 is provided with an outlet pipe 8 communicating with its interior. The upper separation tank 3 is provided with multiple interception mechanisms for intercepting tiny droplets. The interception mechanism includes multiple mounting rods 6 fixedly connected to the inner wall of the upper separation tank 3. A perforated plate 7 is provided on the multiple mounting rods 6. The perforated plate 7 can be made of a metal material (such as titanium alloy), which has high strength and hardness and can maintain shape stability when subjected to large pressure and scouring force.

[0023] The lower separation tank 1 is equipped with a cleaning mechanism for cleaning the perforated plate 7. The cleaning mechanism includes multiple support rods 11 fixedly connected to the inner wall of the lower separation tank 1. A drive housing 10 is fixedly connected to the multiple support rods 11. A drive motor 9 is fixedly connected to the bottom of the drive housing 10. A drive shaft 13 is fixedly connected to the output shaft of the drive motor 9. Multiple brush plates 12 are fixedly connected to the side wall of the drive shaft 13. The brushes of the brush plates 12 are not shown in the figure.

[0024] In this invention, multiple support rods 11 are arranged at equal intervals, which makes the force on the drive housing 10 more uniform. One of the support legs at the lower end of the separation tank 1 is equipped with a controller for the drive motor 9 (not shown in the figure). The upper end of the drive housing 10 is provided with an inclined surface to prevent liquid accumulation.

[0025] In this utility model, a water injection pipe 14 is provided on the side wall of the upper tank 3. A water outlet ring 18 is connected to the upper part of the water injection pipe 14. Multiple nozzles 16 are connected to the lower part of the water outlet ring 18. A valve is provided on the water injection pipe 14, which is not shown in the figure.

[0026] In this utility model, multiple support blocks 17 are fixedly connected to the upper end of the water outlet ring 18. The upper end of the support block 17 is fixedly connected to the inner wall of the separation tank 3, which allows the water outlet ring 18 to be connected to the separation tank 3, making it more stable and preventing it from being blown around by the airflow.

[0027] In this invention, multiple nozzles 16 are arranged at equal intervals, which makes the perforated plate 7 rinse more evenly. Multiple support blocks 17 are arranged at equal intervals. The lower tank 1 is provided with a drain pipe 15 that communicates with its interior. When the liquid contains a lot of impurities, the sewage is discharged from the drain pipe 15 when the perforated plate 7 is being cleaned.

[0028] It should be noted that this utility model is a liquid-gas separation device for a control system. The inlet pipe 2 is connected to the water outlet of the vacuum pump, the outlet pipe 4 is connected to the control system pipeline, the gas outlet pipe 8 is connected to the external recovery device, and the drain pipe 5 is connected to the external liquid storage device. When the vacuum pump sends the liquid in the control system pipeline into the device through the inlet pipe 2, the liquid containing gas falls from the top of the separation tank 1. Due to its higher density, the liquid will gradually settle to the bottom of the container under the action of gravity and be discharged from the outlet pipe 4 for use by the vacuum pump. The gas will rise to the top of the container and be discharged from the outlet pipe 8. During the upward movement of the gas, it passes through multiple porous plates 7. Some of the tiny liquid droplets contained in the gas will be adsorbed by the porous plates 7, thereby improving the overall effect of gas-liquid separation, increasing the possibility of liquid entering the vacuum pump, and reducing the liquid being discharged with the gas.

[0029] When the liquid has high viscosity, some holes in the perforated plate 7 may become clogged after prolonged use. This can be resolved by starting the drive motor 9, which drives the drive shaft 13 to rotate. The drive shaft 13 then drives multiple brush plates 12 to rotate, thereby automatically cleaning the perforated plate 7 and ensuring its normal operation.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
