Description

Technical Field

[0001] This utility model relates to the field of gas-liquid separation technology, specifically a gas-liquid separator. Background Technology

[0002] In a high-temperature steam heating system, after the high-temperature steam is cooled, it needs to pass through a gas-liquid separator to separate the condensate and non-condensable gases. The condensate is returned to the collection tank, while the non-condensable gases enter the next stage through the pump and exhaust pipeline.

[0003] Existing gas-liquid separators are simple tank structures. After the gas-liquid mixture enters the separator, separation is achieved through natural sedimentation of the liquid under gravity. This method suffers from low separation efficiency and insufficient purity of the separated gas, often requiring secondary or tertiary dehumidification, or increasing the tank area and extending pipeline length to improve gravity sedimentation. This prolongs the production line, reduces production efficiency, and also increases the cost and floor space required for the processing equipment. Therefore, we propose a new gas-liquid separator.

The dehumidification mechanism includes two rotating rollers rotatably installed inside the housing. A dehumidifying cloth is driven between the two rotating rollers. One end of the inlet pipe opens towards the bottom of the dehumidifying cloth, and one end of the outlet pipe opens towards the top of the dehumidifying cloth.

[0007] Furthermore, the dehumidification mechanism also includes two symmetrically arranged guide components, each guide component comprising two guide rollers, which respectively contact the top and bottom of the dehumidification cloth.

[0009] Furthermore, the dehumidification mechanism also includes a squeezing roller rotatably mounted on the housing, the surface of which contacts the dehumidifying cloth, and the squeezing roller cooperates with the guide roller to squeeze the dehumidifying cloth.

[0010] Furthermore, the dehumidification mechanism also includes a liquid receiving box inserted into the housing, the liquid receiving box being located below the squeeze roller.

[0011] Furthermore, two baffles are fixedly connected to the inner wall of the housing, and the bottom end of the feed pipe is located between the two baffles.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3 The present invention provides a technical solution as follows:

[0023] A gas-liquid separator includes a housing 1 and an inlet pipe 2 and an outlet pipe 3 connected to the housing 1. A dehumidification mechanism 4 is provided inside the housing 1 and is located between the inlet pipe 2 and the outlet pipe 3 to remove the liquid phase between the inlet pipe 2 and the outlet pipe 3.

[0024] Combination Figure 1 and Figure 2 As shown, the top end of the feed pipe 2 penetrates the shell 1, and the bottom end of the feed pipe 2 extends downward and then bends upward, making the lower part of the pipe U-shaped. This lengthens the feed pipe 2, which is beneficial for gas-liquid separation. The separated liquid phase settles under gravity and concentrates at the bottom of the U-shaped pipe. The bottom end of the U-shaped pipe is provided with a drain port (not shown in the figure) to facilitate the discharge of the separated liquid. The bottom end of the exhaust pipe 3 is connected to a flow guide shroud 301. The end of the flow guide shroud 301 away from the exhaust pipe 3 expands outward into a funnel shape, which can increase the gas collection area.

[0025] Specifically, the dehumidification mechanism 4 in this embodiment includes two rotating rollers 401 rotatably installed inside the housing 1. A dehumidifying cloth 402 is connected between the two rotating rollers 401. The dehumidifying cloth 402 is a flexible material that can absorb moisture. The dehumidifying cloth 402 is circular around the two rotating rollers 401. One end of the feed pipe 2 opens towards the bottom of the dehumidifying cloth 402, and one end of the exhaust pipe 3 opens towards the top of the dehumidifying cloth 402. This allows the gas-liquid mixture to pass through the double-layer dehumidifying cloth 402 before being discharged from the device. The liquid phase in the mixture is filtered and adsorbed by the double-layer dehumidifying cloth 402. Compared with the traditional gravity sedimentation method, the dehumidification effect is better.

[0026] Please see Figure 2 The dehumidification mechanism 4 also includes two guide components. The two guide components are symmetrically arranged with the center line of the exhaust pipe 3 as the axis of symmetry. The two guide components are on the same horizontal line and are both arranged on the horizontal section of the annular dehumidification cloth 402. Specifically, the guide components include two guide rollers 403. The two guide rollers 403 contact the top and bottom of the dehumidification cloth 402 respectively. The distance between the two guide rollers 403 is twice the thickness of the dehumidification cloth 402. The middle horizontal section of the dehumidification cloth 402 can be contracted by the two guide rollers 403, so that the dehumidification cloth 402 adsorbs the liquid phase in a double layer.

[0027] To ensure the dehumidifying cloth 402 rotates cyclically, the dehumidification mechanism 4 also includes a drive motor 407 fixedly mounted on the housing 1. The output end of the drive motor 407 is connected to a drive shaft 406, which is rotatably mounted on the housing 1. Two drive gears 405 are fixedly mounted on the drive shaft 406. Toothed belts 404 are fixedly connected to both sides of the dehumidifying cloth 402, and each toothed belt 404 meshes with one of the drive gears 405. The toothed belts 404 have external teeth to facilitate cooperation with the guide assembly and the rotating roller 401, preventing motion interference.

[0028] In addition, the dehumidification mechanism 4 also includes a squeezing roller 408 rotatably mounted on the housing 1. The surface of the squeezing roller 408 contacts the dehumidifying cloth 402. The distance between the squeezing roller 408 and the guide roller 403 is less than the maximum thickness of the dehumidifying cloth 402. Through the cooperation of the squeezing roller 408 and the guide roller 403, the dehumidifying cloth 402 can be squeezed, thereby squeezing out the liquid inside the dehumidifying cloth 402. When the dehumidification mechanism 4 is working, the drive motor 407 drives the drive shaft 406 to rotate. The drive shaft 406 synchronously drives the two drive gears 405 fixedly connected to it to rotate. The drive gears 405 drive the toothed belt 404 to rotate through meshing, thereby driving the dehumidifying cloth 402 to rotate around a fixed trajectory. When the dehumidifying cloth 402 passes between the feed pipe 2 and the exhaust pipe 3, it can adsorb the liquid phase in the gas-liquid mixture. Subsequently, the dehumidifying cloth 402 is squeezed by the squeezing roller 408, squeezing out the liquid phase inside. The liquid phase drips down the squeezing roller 408. The dehumidification mechanism 4 also includes a liquid receiving box 409 inserted into the housing 1. The liquid receiving box 409 is located below the squeezing roller 408. The dripping liquid phase falls into the liquid receiving box 409 and is collected. Since the liquid receiving box 409 is inserted into the housing 1, it is easy to pull out the liquid receiving box 409 and treat the liquid inside. It is worth noting that two sets of squeezing roller 408 and liquid receiving box 409 can be provided to improve the liquid squeezing effect.

[0029] Due to the cooperation of the two sets of guiding components, the gas-liquid mixture can be prevented from diffusing into the area enclosed by the dehumidifying cloth 402 and adhering to the rotating roller 401, thus making the dehydration effect of the squeezing roller 408 better.

[0030] In addition, two baffles 5 are fixedly connected to the inner wall of the housing 1, and the bottom end of the feed pipe 2 is located between the two baffles 5. By setting the two baffles 5, the moisture absorption area of ​​the dehumidifying cloth 402 can be separated from the squeezing area, preventing the gas-liquid mixture from spreading to the entire coverage area of ​​the dehumidifying cloth 402. As a result, after the squeezing roller 408 squeezes the liquid in the dehumidifying cloth 402, the dehumidifying cloth 402 can maintain a certain degree of dryness, thereby improving the liquid absorption effect of the dehumidifying cloth 402 between the feed pipe 2 and the exhaust pipe 3.

[0031] When the gas-liquid separator of this utility model is in use, the drive motor 407 is started, and the output end of the drive motor 407 synchronously drives the drive shaft 406 to rotate. The drive shaft 406 synchronously drives the two drive gears 405 fixedly connected to it to rotate. The drive gears 405 drive the toothed belt 404 to rotate through meshing, thereby driving the dehumidifying cloth 402 to rotate around a fixed trajectory.

[0032] A gas-liquid mixture is fed into the device from the top of the feed pipe 2. As the mixture flows through the irregular feed pipe 2, the liquid phase settles under gravity, achieving initial gas-liquid separation. The remaining unseparated mixture is discharged from the bottom of the feed pipe 2. The mixture passes through two layers of dehumidifying cloth 402 and moves upward. The liquid phase in the mixture is adsorbed by the dehumidifying cloth 402, while the gas phase passes through the dehumidifying cloth 402 and enters the guide shroud 301, finally being discharged through the exhaust pipe 3.

[0033] After the dehumidifying cloth 402 absorbs the liquid phase, it continues to rotate. When it passes the squeezing roller 408, it is squeezed by the squeezing roller 408 and the rotating roller 401, squeezing out the liquid phase inside. The liquid phase drips down the squeezing roller 408 and enters the liquid receiving box 409 inside the squeezing roller 408 for collection. After a period of time, the liquid receiving box 409 can be pulled out of the housing 1 and replaced with a clean liquid receiving box 409. During the extraction process, the presence of the baffle 5 can prevent a large amount of gas-liquid mixture from leaking out of the housing 1.
