Description

Technical Field

[0001] This utility model relates to the field of gas-liquid separation technology, and in particular to a gas-liquid separator that combines multiple separation methods. Background Technology

[0002] Gas-liquid separators are widely used in various industrial applications. The function of a gas-liquid separator is to separate gas and liquid as much as possible. After passing through the gas-liquid separator, the liquid is liquid and does not contain gas; while the gas is gas and does not contain liquid.

[0003] Gas-liquid separators employ various separation structures and methods, including gravity sedimentation, baffle separation, centrifugal separation, wire mesh separation, ultrafiltration separation, and packing separation.

[0004] In water electrolysis hydrogen production equipment, the most commonly used separation structure is wire mesh separation.

[0005] The wire mesh separation method is mainly used for the secondary filtration and separation of gases. That is to say, the gas-liquid mixture in the tank needs to be separated into gases first, and then the gas is filtered and separated again by the wire mesh. However, the separation efficiency of the single wire mesh separation method is relatively low. Utility Model Content

[0006] The technical problem to be solved by this utility model is: in order to solve the technical problems in the prior art, this utility model provides a gas-liquid separator with multiple separation methods combined.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a gas-liquid separator with multiple separation methods combined, including a tank; a feed pipe disposed on the tank; a gas outlet pipe disposed on the top surface of the tank; a liquid outlet pipe disposed at the bottom of the tank; a wire mesh filter disposed on the gas outlet pipe; a cyclone tube connected to the bottom of the feed pipe; and an impactor disposed inside the tank, wherein the impactor is arranged facing the output end of the cyclone tube.

[0008] This utility model discloses a gas-liquid separator that combines multiple separation methods. By increasing the turbulence of the gas-liquid mixture output from the feed pipe through a cyclone tube, the gas-liquid two-phase separation is achieved. Subsequently, the gas-liquid mixture impacts the impact member, which further accelerates the separation speed of the gas and liquid two-phase separation, thereby improving the gas-liquid separation effect and efficiency.

[0009] Furthermore, the cyclone tube is provided with cyclone fins, and multiple cyclone fins are arranged in a circumferential array along the cyclone tube, forming a cyclone channel between two adjacent cyclone fins.

[0010] Furthermore, the impactor is inclined so that it is approximately perpendicular to the trajectory of the gas-liquid mixture output from the cyclone tube.

[0011] Furthermore, the impact member includes a first inclined plate and a second inclined plate connected to each other, with the junction of the first inclined plate and the second inclined plate positioned directly opposite the output direction of the cyclone tube.

[0012] Furthermore, the angle between the first inclined plate and the second inclined plate is 120 degrees to 180 degrees.

[0013] Furthermore, the tank body is provided with a barrier, which is located between the feed pipe and the air outlet pipe.

[0014] Furthermore, the barrier includes a barrier steel plate, the bottom of which is provided with a liquid passage groove, and the top of which is provided with a gas passage groove.

[0015] Furthermore, a first diversion hole is provided at the center of the barrier steel plate.

[0016] Furthermore, the barrier steel plate is also provided with a second diversion hole, which is arranged in a circumferential array on the outside of the first diversion hole.

[0017] Furthermore, the second diversion hole is provided in multiple sets along the radial direction of the first diversion hole.

[0018] The beneficial effects of this utility model are:

[0019] 1. By increasing the turbulence of the gas-liquid mixture output from the feed pipe through the cyclone tube, the gas and liquid phases are separated. Subsequently, the gas-liquid mixture impacts the impacting element, which further accelerates the separation speed of the gas and liquid phases, thereby improving the gas-liquid separation effect and efficiency.

[0020] 2. By setting the impactor and the trajectory of the gas-liquid mixture output from the cyclone tube to be approximately perpendicular, the impact force of the gas-liquid mixture hitting the impactor will be greater, thereby improving the gas-liquid separation efficiency.

[0021] 3. By setting the first and second inclined plates at an angle of 120 to 180 degrees, the intensity of the gas-liquid mixture impact is further increased. At the same time, the first and second inclined plates guide the impacted gas-liquid mixture to both sides as much as possible, further improving the gas-liquid mixing effect.

[0022] 4. By using barrier components to block the fluid entering the tank, the reaction time of the gas-liquid mixture is increased, allowing more gas to be separated within the tank, reducing the burden on the wire mesh filter components, and thus improving the effect and efficiency of gas-liquid separation.

[0023] 5. The liquid passage facilitates the passage of liquid, and the gas passage facilitates the passage of gas. The first and second diversion holes further divide the gas-liquid mixture, which helps to improve the gas-liquid separation effect. Attached Figure Description

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] This utility model discloses a gas-liquid separator that combines multiple separation methods.

[0033] Reference Figure 1 and Figure 2 A gas-liquid separator employing a combination of separation methods includes a horizontally positioned tank 1. An inlet pipe 11, an outlet pipe 12, and a liquid outlet pipe 13 are fixedly connected to the tank 1. The inlet pipe 11 is used for feeding gas; the outlet pipe 12 is located at the top of the tank 1 and is used to discharge gas; the liquid outlet pipe 13 is located at the bottom of the tank 1 and is used to discharge liquid. A wire mesh filter 15 is installed inside the outlet pipe 12 to facilitate gas filtration and further improve gas purity. A barrier 14 is provided inside the tank 1, located between the inlet pipe 11 and the outlet pipe 12. During operation, the barrier 14 blocks the gas-liquid mixture entering the tank 1, increasing the fluid's reaction time and allowing more gas to separate within the tank 1, reducing the burden on the wire mesh filter 15, thereby improving the gas-liquid separation effect and efficiency.

[0034] Specifically, the barrier component 14 includes a barrier steel plate 141, which is welded to the inner wall of the tank 1. The bottom of the barrier steel plate 141 has a liquid passage 142, and the top of the barrier steel plate 141 has a gas passage 143. A first diversion hole 144 is located at the center of the barrier steel plate 141, and a second diversion hole 145 is also provided on the barrier steel plate 141. The second diversion holes 145 are arranged in a circumferential array around the first diversion hole 144. Multiple sets of the second diversion holes 145 are arranged radially along the first diversion hole 144; in this embodiment, there are two sets. Multiple barrier steel plates 141 are arranged circumferentially around the tank 1; in this embodiment, there are two.

[0035] In addition, a flange 111 is connected to the feed pipe 11, and the feed pipe 11 and the flange 111 are connected by a reducing pipe 112. The reducing pipe 112 is a tapered pipe, with its large end fixedly connected to the flange 111 and its small end fixedly connected to the feed pipe 11. By reducing the pipe diameter, the flow velocity of the gas-liquid mixture in the feed pipe 11 is increased, facilitating the collision of the gas-liquid mixture with the inner wall of the tank 1 after it enters the tank, thereby improving the gas-liquid separation effect. The bottom of the feed pipe 11 extends into the tank 1 and is connected to a back pipe 113. The outlet end of the back pipe 113 is located away from the gas outlet pipe 12, and the back pipe 113 is curved to increase the inertial force of the gas-liquid mixture output from the back pipe 113 through its curve. The back pipe 113 increases the time for the gas-liquid mixture to flow to the liquid outlet pipe 13 and the gas outlet pipe 12, further improving the gas-liquid separation effect and efficiency.

[0036] Reference Figure 3 and Figure 4 The output end of the back-flow pipe 113 is also fixedly connected to a cyclone pipe 17, and an impact element 18 is also provided inside the tank body 1, with the impact element 18 facing the output end of the cyclone pipe 17. During operation, the cyclone pipe 17 increases the turbulence of the gas-liquid mixture output from the feed pipe 11, thereby achieving the separation of the gas and liquid phases. Subsequently, the gas-liquid mixture impacts the impact element 18, further accelerating the separation speed of the gas and liquid phases through the impact, thus improving the gas-liquid separation effect and efficiency.

[0037] Specifically, swirl fins 171 are fixedly connected inside the swirl tube 17. Multiple swirl fins 171 are arranged in a circumferential array along the swirl tube 17, and a swirl channel 172 is formed between two adjacent swirl fins 171. This intensifies the swirl of the gas-liquid mixture passing through the swirl channel 172, achieving the effect of cyclone separation. The impact member 18 is inclined so that the trajectory of the impact member 18 is approximately perpendicular to the trajectory of the gas-liquid mixture output from the swirl tube 17, thereby increasing the impact force of the gas-liquid mixture hitting the impact member 18.

[0038] More specifically, the impact member 18 includes a first inclined plate 181 and a second inclined plate 182 fixedly connected to each other. The junction of the first inclined plate 181 and the second inclined plate 182 is positioned directly opposite the output direction of the cyclone tube 17, and the included angle between the first inclined plate 181 and the second inclined plate 182 is 120 degrees to 180 degrees. By setting the first inclined plate 181 and the second inclined plate 182 at an angle of 120 degrees to 180 degrees, the intensity of the gas-liquid mixture impact is further enhanced. At the same time, the first inclined plate 181 and the second inclined plate 182 guide the impacted gas-liquid mixture to both sides as much as possible, further improving the gas-liquid mixing effect.

[0039] A vortex breaker 16 is installed on the liquid outlet pipe 13 to facilitate the breaking of liquid vortices or swirls, reduce pipe resistance, and improve transmission efficiency.

[0040] It should be noted that the wire mesh filter element 15 is the wire mesh mist eliminator.

[0041] Working principle: The fluid entering the tank 1 is blocked by the blocking steel plate 141, the liquid passage 142 facilitates the passage of liquid, and the gas passage 143 facilitates the passage of gas. The first diversion hole 144 and the second diversion hole 145 further divert the gas-liquid mixture, increase the reaction time of the gas-liquid mixture, so that more gas is separated in the tank 1, reducing the burden on the wire mesh filter element 15, thereby improving the effect and efficiency of gas-liquid separation.

[0042] The turbulence of the gas-liquid mixture output from the feed pipe is increased by a cyclone tube, achieving gas-liquid phase separation. The gas-liquid mixture then impacts an impactor, further accelerating the separation and improving separation efficiency. The near-perpendicular arrangement of the impactor and the trajectory of the gas-liquid mixture from the cyclone tube results in a greater impact force, further enhancing separation efficiency. The inclined first and second plates, with an angle of 120 to 180 degrees, further intensify the impact, while simultaneously guiding the impacted mixture laterally to enhance mixing.

[0043] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
