Description

Technical Field

[0001] This utility model belongs to the field of gas-liquid separator technology, and in particular relates to a gas-liquid separator that facilitates liquid drainage. Background Technology

[0002] Gas-liquid separators are industrial devices used to separate gas and liquid mixtures. They achieve efficient gas-liquid two-phase separation through physical principles such as gravity, centrifugal force, and inertial collision, and are widely used in petrochemical, energy, environmental protection, and pharmaceutical fields.

[0003] In existing technologies, gas and liquid separate into layers due to their density difference, with the liquid sinking and the gas rising to complete the gas-liquid separation. However, in the process of using existing gas-liquid separators, when it is necessary to discharge the liquid inside the device, liquid tends to remain on the surface of the demister and umbrella plate in the inner cavity, which is not conducive to the liquid discharge operation. Utility Model Content

[0004] This invention provides a gas-liquid separator that facilitates liquid drainage, aiming to solve the problem that in existing gas-liquid separators, when liquid needs to be drained from the device, liquid tends to remain on the surface of the demister and umbrella plate inside the cavity, which is not conducive to the drainage process.

[0005] This utility model is implemented as follows: a gas-liquid separator that facilitates liquid drainage includes a separator body, an injection pipe connected to the lower part of the side wall of the separator body, an exhaust pipe connected to the upper part of the side wall of the separator body, and an L-shaped baffle corresponding to the injection pipe fixedly connected to the inner wall surface of the separator body. The separator body has several umbrella-shaped plates fixedly connected to its inner cavity, which are evenly arranged along its height direction. Several drain ports are opened on the surface of the umbrella-shaped plates. A demister is provided at the top of the inner cavity of the separator body. A rotating rod is rotatably connected between the multiple umbrella-shaped plates. Several scrapers adapted to the drain ports are fixedly connected to the surface of the rotating rod. A drain pipe is connected to the bottom of the separator body.

[0006] Preferably, a support cylinder is fixedly connected to the bottom of the separator body, and a motor located in the inner cavity of the separator body is vertically fixedly connected to the bottom of the separator body, with the output shaft of the motor fixedly connected to the bottom end of the rotating rod.

[0007] Preferably, the other end of the drain pipe extends to the outside of the support cylinder and is equipped with a valve.

[0008] Preferably, an elastic sheet is fixedly connected to the bottom of the demister, a disc is fixedly connected to the top of the rotating rod, and a protrusion that can contact the surface of the elastic sheet is fixedly connected to the upper surface of the disc.

[0009] Preferably, both the injection pipe and the exhaust pipe are provided with flanges at their outer ends.

[0010] Preferably, the top of the separator body is provided with a maintenance cover that can be removed by a group of bolts, and the lower part of the side wall of the separator body is provided with a level gauge interface.

[0011] Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a gas-liquid separator that facilitates liquid drainage. After a gas-liquid mixture is injected into the inner cavity of the separator body through the injection pipe, an L-shaped baffle disperses the mixture, causing the gas to rise and the liquid to sink. During the gas rise, multiple umbrella-shaped baffles separate larger water droplets entrained in the gas, causing the water droplets to condense on the surface of the baffles and drip through the drain port. A demister then intercepts and separates the smaller water droplets carried in the gas flow, thus facilitating the separation of the gas-liquid mixture. To achieve better separation, when the drain pipe is opened to drain the liquid from the inner cavity of the separator, the rotating rod rotates, which drives the scraper to scrape the surface of the drain port, thereby scraping off the water droplets attached to the surface of the drain port, improving the thoroughness of draining the liquid from the inner cavity of the separator. The rotating rod also drives the disc to rotate, and after the protrusion contacts the elastic plate, the elastic deformation causes the demister to vibrate, thereby shaking off the water droplets attached to the surface of the demister, improving the drainage effect of the inner cavity of the separator and facilitating the drainage operation of the separator body.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] First Embodiment Please see Figure 1-4 This utility model provides a technical solution: a gas-liquid separator that facilitates liquid drainage, including a separator body 1, an injection pipe 3 connected to the lower part of the side wall of the separator body 1, an exhaust pipe 4 connected to the upper part of the side wall of the separator body 1, and an L-shaped baffle 7 corresponding to the injection pipe 3 fixedly connected to the inner wall surface of the separator body 1. The inner cavity of the separator body 1 is fixedly connected to several umbrella plates 2 evenly arranged along its height direction. Several drain ports 6 are opened on the surface of the umbrella plates 2. A demister 10 is provided at the top of the inner cavity of the separator body 1. A rotating rod 8 is rotatably arranged between the multiple umbrella plates 2. Several scrapers 9 adapted to the drain ports 6 are fixedly connected to the surface of the rotating rod 8. A drain pipe 16 is connected to the bottom of the separator body 1.

[0016] In this embodiment, after the injection pipe 3 injects the gas-liquid mixture into the inner cavity of the separator body 1, the L-shaped baffle 7 disperses the gas-liquid mixture, the gas rises and the liquid sinks. During the gas rise, multiple umbrella plates 2 are used to separate the larger water droplets entrained in the gas, so that the water droplets condense on the surface of the umbrella plate 2 and drip down through the drain port 6. Then, the demister 10 is used to intercept and separate the small water droplets carried in the airflow, thereby facilitating better separation of the gas-liquid mixture.

[0017] When the drain pipe 16 is opened to drain the liquid from the inner cavity of the separator body 1, the rotating rod 8 rotates, which drives the scraper 9 to scrape the surface of the drain port 6, thereby scraping off the water droplets attached to the surface of the drain port 6 and improving the thoroughness of draining the liquid from the inner cavity of the separator body 1.

[0018] A support cylinder 14 is fixedly connected to the bottom of the separator body 1. A motor 15 located in the inner cavity of the separator body 1 is vertically fixedly connected to the bottom of the separator body 1. The output shaft of the motor 15 is fixedly connected to the bottom end of the rotating rod 8. After the motor 15 is working, it can drive the rotating rod 8 to rotate, thereby driving multiple umbrella plates 2 to rotate.

[0019] The other end of the drain pipe 16 extends to the outside of the support cylinder 14 and is equipped with a valve 19. After opening the valve 19, the liquid at the bottom of the inner cavity of the separator body 1 can be discharged through the drain pipe 16.

[0020] Second Embodiment Please refer to Figure 4Based on the same concept as the first embodiment described above, the bottom of the demister 10 is fixedly connected to an elastic sheet 13, the top of the rotating rod 8 is fixedly connected to a disc 11, and the upper surface of the disc 11 is fixedly connected to a protrusion 12 that can contact the surface of the elastic sheet 13.

[0021] In this embodiment, the rotating rod 8 drives the disc 11 to rotate. After the protrusion 12 contacts the elastic sheet 13, the elastic deformation causes the demister 10 to vibrate, thereby shaking off the residual water droplets attached to the surface of the demister 10, improving the drainage effect of the separator body 1 and facilitating the drainage operation of the separator body 1.

[0022] Both the injection pipe 3 and the exhaust pipe 4 are equipped with flanges 5 at their outer ends. The flanges 5 facilitate the connection of external piping systems with the injection pipe 3 and the exhaust pipe 4.

[0023] The top of the separator body 1 is fitted with a maintenance cover 18 that is removed by several bolt groups 17, and a level gauge interface 20 is provided on the lower part of the side wall of the separator body 1.

[0024] The working principle and usage process of this utility model are as follows: After the utility model is installed, the injection pipe 3 injects a gas-liquid mixture into the inner cavity of the separator body 1. The L-shaped baffle 7 disperses the gas-liquid mixture, causing the gas to rise and the liquid to sink. During the gas rising process, multiple umbrella plates 2 are used to separate larger water droplets entrained in the gas, causing the water droplets to condense on the surface of the umbrella plates 2 and drip down through the drain port 6. Then, the demister 10 intercepts and separates the tiny water droplets carried in the airflow, thus facilitating better separation of the gas-liquid mixture. When the separator body 1 is in operation, during the process of draining liquid from the inner cavity of the separator body 1 by opening the drain pipe 16, the rotating rod 8 rotates, which drives the scraper 9 to scrape the surface of the drain port 6, thereby scraping off the water droplets attached to the surface of the drain port 6, improving the thoroughness of draining liquid from the inner cavity of the separator body 1. The rotating rod 8 drives the disc 11 to rotate, and after the protrusion 12 contacts the elastic sheet 13, the elastic deformation drives the demister 10 to vibrate, thereby shaking off the water droplets attached to the surface of the demister 10, improving the draining effect of the inner cavity of the separator body 1.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
