Description

Technical Field

[0001] The present invention relates to the technical field of gas-liquid separation, and in particular to a gas-liquid separation device and a gas-liquid separation method. Background Art

[0002] Roots vacuum pump is a device used to create a high vacuum. Its main function is to discharge gas from an area to make the area reach the required vacuum degree. Inside its pump are two impellers that rotate synchronously in opposite directions. By controlling the two impellers to rotate asynchronously, it can inhale and discharge gas.

[0003] Because there is a gap between the two impellers, the vibration is large, so the low-frequency noise is high and the noise frequency band is wide. Therefore, when using Roots vacuum pumps, it is usually necessary to install a muffler to achieve the noise reduction function. When making guide gas, Roots vacuum pumps are usually used, but when guiding gas, the gas is usually mixed with liquids such as water.

[0004] At present, the exhaust muffler used in the operation of the new wet Roots vacuum pump on the market is usually arranged separately from the gas-liquid separation equipment in engineering applications, which makes the entire equipment bulky and cumbersome to install. In addition, the low-frequency silencing effect of the ordinary new wet Roots vacuum pump exhaust muffler is poor when it is used.

[0005] This is mainly because when the soda and water enter the gas-liquid separation component, the flow rate is very high. After the gas-liquid separation component is washed by the airflow, it vibrates violently, which in turn causes the silencer to vibrate together, thereby making the silencer effect worse. If the gas-liquid separation component is set separately, the volume of the entire device is often larger. In addition, after the separate setting, it is necessary to increase the installation process of the equipment, that is, it is necessary to install and connect the gas-liquid separation component and the silencer in sequence.

[0006] On the other hand, after the existing gas-liquid separation assembly separates the liquid, because too much liquid is deposited on the path of gas flow, some of the trapped liquid is still carried away by the airflow, thus affecting the effect of gas-liquid separation.

DETAILED DESCRIPTION

[0036] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0037] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0038] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "one" cannot be understood as a limitation on the number. The mixed water vapor includes gas and water. The steam-water separation silencer of the vacuum pump is used to separate the gas and the water in the mixed water vapor, and can collect the separated water for subsequent recycling. In addition, the steam-water separation device can also effectively eliminate the noise generated when the gas passes through the vacuum pump.

[0039] refer to Figures 1 to 7 The gas-liquid separation device includes a device body 10 and a gas-liquid separation component 20.

[0040] Preferably, the device body 10 is implemented to have a certain height, thereby forming a low end 11 and a high end 12. The device body 10 forms a cavity 101 between the high end 12 and the low end 11, and forms an outlet 103 at the high end 12, and the outlet 103 is arranged to communicate with the cavity 101.

[0041] The gas-liquid separation component 20 is installed in the cavity 101. Specifically, the gas-liquid separation component 20 is arranged in the cavity 101 close to the lower end 11 to remove the gas-liquid mixture entering the cavity 101.

[0042] Specifically, the gas-liquid separation assembly 20 includes a gas-liquid separation component 21 and a potential core reduction cylinder 22 .

[0043] The gas-liquid separation member 21 includes a first isolation plate 211 and a plurality of gas-liquid separation columns 212. The first isolation plate 211 is sealedly mounted on the inner wall of the cavity 101 to separate the cavity 101 into two upper and lower independent chambers, namely an upper chamber 101A and a lower chamber 101B.

[0044] In addition, the first isolation plate forms a plurality of first mounting holes 21101 arranged at intervals along the radial direction, wherein the peripheral side of the bottom of each gas-liquid separation column 212 is sealedly connected to the inner wall forming each first mounting hole 21101. At least one first axial hole 21201 is formed at the bottom of each gas-liquid separation column 212, the bottom of each gas-liquid separation column 212 is vertically mounted on the first mounting hole 21101, and a plurality of first radial holes 21202 are formed on the side wall of each gas-liquid separation column 212. The first axial hole 21201 and the first radial hole 21202 are connected through the inside of the gas-liquid separation column 212, wherein the first axial hole 21201 is connected to the lower chamber 101B, and the first radial hole 21202 is connected to the upper chamber 101A in the upper chamber 101A.

[0045] It is worth mentioning that since the top of the gas-liquid separation column 212 is closed, the gas flowing in from the first axial hole 21201 can only change direction and flow out radially through the first radial hole 21202. In this way, the flow rate of the gas can be effectively reduced, and more liquid in the gas can be retained by the gas-liquid separation component 21, thereby improving the gas-liquid separation effect.

[0046] It is worth mentioning that the diameter of the first radial hole 21202 on the gas-liquid separation column 212 is less than or equal to 20 mm, and the opening rate is 15% to 20%.

[0047] Furthermore, the potential core reduction tube 22 has an air inlet 2201 that passes through the lower end 11 of the device body 10 in a radial direction, wherein the potential core reduction tube 22 extends from the air inlet 2201 in a radial direction toward the inside of the cavity 101 to form an air inlet cavity 2202, wherein the air inlet 2201 is connected to the air inlet cavity 2202. The other side of the potential core reduction tube 22 opposite to the air inlet 2201 is blocked. The outer wall of the potential core reduction tube 22 is provided with a plurality of potential core reduction holes 22201. Preferably, Figure 5 As shown, the potential core reduction cylinder 22 extends outward to form the air inlet 2201 , wherein the air inlet 2201 of the potential core reduction cylinder 22 maintains a seal with the equipment main body 10 when passing through the equipment main body 10 .

[0048] It is worth mentioning that, in this way, the lower chamber 101B will be connected to the air inlet chamber 2202 through the potential elimination core hole 22201.

[0049] Preferably, the total area of ​​the plurality of first radial holes 21202 is greater than 1.5 times the cross-sectional area of ​​the air inlet 2201 .

[0050] Preferably, the potential core reduction cylinder 22 has a cylinder top 221 close to the high end portion 12 and a non-cylinder top 222 away from the high end portion 12, wherein the outer wall of the non-cylinder top 222 is provided with a plurality of potential core elimination holes 22201. That is, the cylinder top 221 is not provided with the potential core elimination holes 22201. It is worth mentioning that the total area of ​​the plurality of potential core elimination holes 22201 is greater than 1.5 times the cross-sectional area of ​​the air inlet 2201. In this way, after the high-speed gas mixed with liquid enters the potential core reduction cylinder 22 from the air inlet 2201, the high-speed airflow potential core can be effectively and quickly dispersed.

[0051] In addition, the potential core reduction cylinder 22 is preferably such that the distance between the outer walls on both sides of the non-cylinder top 222 and the inner wall forming the cavity 101 is greater than 5 times the distance of the air inlet 2201. In this way, after the high-speed airflow enters the air inlet cavity 2202 from the air inlet 2201, the cylinder wall forming the cavity 101 can be prevented from being located in the potential core destruction area of ​​the airflow, thereby effectively reducing the vibration and noise generated by the high-speed airflow.

[0052] Theoretically, the more potential core elimination holes 22201 there are, the better. However, if there are more potential core elimination holes 22201, the volume of the potential core elimination tube 22 will be larger, which is not conducive to site installation and cost control. Preferably, the potential core elimination tube 22 has sufficient strength and rigidity. Preferably, the opening rate of the potential core elimination tube 22 is 20% to 25%. Such an arrangement can not only effectively make the gas-liquid separation device suitable for the wind speed of the existing Roots blower, but also effectively reduce the vibration and noise caused by the high-speed airflow. More importantly, such an arrangement of the potential core elimination tube 22 can effectively throttle the liquid in the airflow, and make the liquid in the airflow fall to the bottom of the lower chamber 101B under the action of gravity after passing through the potential core elimination holes 22201.

[0053] Preferably, the gas-liquid separation component 20 also includes at least one liquid guide tube 23, wherein the upper portion of the liquid guide tube 23 is arranged to pass through the first isolation plate 211 and is connected to the upper chamber 101A, wherein the lower portion of the liquid guide tube 23 is arranged to extend downward to the lower chamber 101B, so that the liquid accumulated on the top of the first isolation plate 211 in the upper chamber 101A after being intercepted by the gas-liquid separation column 212 can be guided downward to the lower chamber 101B through the liquid guide tube 23.

[0054] Preferably, the bottom of the liquid guide tube 23 is located lower than the bottom of the potential core elimination tube 22, and the liquid guide tube 23 and the potential core elimination tube 22 are staggered in the lower chamber 101B. In this way, it is possible to avoid the airflow flowing out through the potential core elimination hole 22201 from guiding the water flow flowing out of the bottom of the liquid guide tube 23 to the upper chamber 101A again.

[0055] It is worth mentioning that at least one of the potential core elimination holes 22201 disposed on the non-tube top 222 is oriented toward the bottom opening of the liquid conduit 23. It can be understood by those skilled in the art that, since the bottom of the liquid conduit 23 is located lower than the bottom of the potential core elimination tube 22, the potential core elimination hole 22201 oriented toward the bottom opening of the liquid conduit 23 will only guide the liquid flowing out of the bottom opening of the liquid conduit 23 to the lower chamber 101B. At the same time, since the airflow at the bottom opening of the liquid conduit 23 is flushed through the potential core elimination hole 22201, a negative pressure can be formed, and the liquid on the top of the first isolation plate 211 after being intercepted and accumulated in the upper chamber 101A is better guided to the bottom of the lower chamber 101B, so as to avoid excessive liquid deposition and affect the effect of gas-liquid separation.

[0056] Preferably, the gas-liquid separation component 20 includes at least two liquid guide tubes 23 .

[0057] More preferably, the gas-liquid separation component 20 includes a pair of intercepting plates 24. The intercepting plates 24 are arranged in the lower chamber 101B and between the potential core reduction cylinder 22 and the first isolation plate 211, wherein the pair of intercepting plates 24 are symmetrical with respect to the vertical plane in the axial direction of the potential core reduction cylinder 22, and are fixed obliquely to the inner wall of the lower chamber 101B. A high-pass opening 2401 is formed between the tops of the pair of intercepting plates 24, and a low-pass opening 2402 having a cross-sectional area larger than the high-pass opening 2401 is formed between the bottoms of the pair of intercepting plates 24. In other words, the intercepting plates 24 are obliquely arranged in the lower chamber 101B.

[0058] refer to Figure 7 Preferably, in a vertical section perpendicular to the axial direction of the potential core reduction tube 22, the distance (d1) between each side of the tube top 221 and the inner wall of the lower chamber 101B on the corresponding side is smaller than the distance (d2) between one end of the high-pass opening 2401 formed on the intercepting plate 24 on the same side and the inner wall of the lower chamber 101B on that side. In this way, the airflow flowing out through the potential core elimination hole 22201 on the potential core reduction tube 22 not only changes its flow direction, but also is blocked by the intercepting plate 24 and further redirected, thereby retaining more liquid in the airflow and achieving a better gas-liquid separation effect. At the same time, such a setting can prevent the airflow flowing out through the potential core elimination hole 22201 on the potential core reduction tube 22 from flowing directly from the low-pass opening 2402 to the high-pass opening 2401 without being intercepted.

[0059] In addition, the cross-sectional area of ​​the high-through opening 2401 is also 1.5 times greater than the cross-sectional area of ​​the air inlet 2201 .

[0060] Preferably, the angle between the plane where the intercepting plate 24 is located and the cross-sectional direction is 15° to 35°, so as to facilitate the liquid intercepted by the intercepting plate 24 to be guided to the inner wall of the lower chamber 101B and then flow to the bottom of the lower chamber 101B.

[0061] Furthermore, at least one leakage hole 2403 is provided at the position where the low-pass opening 2402 is formed on the intercepting plate 24 , so that the liquid between the intercepting plate 24 and the inner wall forming the cavity 101 can fall through the leakage hole 2403 .

[0062] Preferably, the liquid guiding tube 23 is arranged to pass through the intercepting plate 24 , and in a modified embodiment, the liquid leakage hole 2403 is arranged at a position where the liquid guiding tube 23 is just connected to the intercepting plate 24 and is located on the upper side of the intercepting plate 24 .

[0063] Furthermore, the gas-liquid separation device includes a silencer assembly 30, and the silencer assembly 30 is disposed in the cavity 101 to reduce the noise generated when the gas passes through.

[0064] Specifically, the silencer assembly 30 is disposed in the upper chamber 101A and is located above the gas-liquid separation component 21 .

[0065] More specifically, the muffler assembly 30 includes a second isolation plate 31 and a plurality of low-frequency muffler columns 32 .

[0066] In addition, the second isolation plate 31 forms a plurality of second mounting holes 3101 spaced apart in the radial direction, wherein the peripheral side of the bottom of each of the low-frequency silencer columns 32 is sealingly connected to the inner wall forming each of the second mounting holes 3101, so as to separate the upper chamber 101A into an upper noise reduction chamber 101A1 and a lower fluid chamber 101A2.

[0067] At least one second axial hole 3201 is formed at the bottom of each low-frequency muffler column 32, and the bottom of each low-frequency muffler column 32 is vertically mounted on the second mounting hole 3101, and a plurality of second radial holes 3202 are formed on the side wall of each low-frequency muffler column 32. The second axial hole 3201 and the second radial hole 3202 are connected through the interior of the low-frequency muffler column 32, wherein the second axial hole 3201 is connected to the lower fluid chamber 101A2, and the second radial hole 3202 is connected to the upper noise reduction chamber 101A1 in the upper noise reduction chamber 101A1.

[0068] It is worth mentioning that the total cross-sectional area of ​​all the second radial holes 3202 is greater than the total cross-sectional area of ​​all the first radial holes 21202 of the gas-liquid separation column 212, so that the resistance loss can be effectively reduced and the low-frequency noise in the airflow can be effectively eliminated. Preferably, the aperture expansion ratio of the cross-sectional mutation of the second radial hole 3202 is 20 to 30 times, and the opening rate is 15%.

[0069] More preferably, the muffler assembly 30 further includes a high-frequency muffler component 33, wherein the high-frequency muffler component 33 is disposed in the upper noise reduction chamber 101A1 and is located above the low-frequency muffler column 32. In a preferred embodiment, the high-frequency muffler component 33 is configured as a resistive sheet muffler.

[0070] Preferably, the total cross-sectional area of ​​the passage when the airflow passes through the resistive sheet muffler is greater than 2 times the cross-sectional area of ​​the air inlet 2201. Preferably, the spacing between the muffler sheets of the resistive sheet muffler is less than 100 mm, and the equivalent diameter of the muffler passage formed by the resistive sheet muffler is less than 1000 mm. In this way, a smaller structural resistance coefficient can be obtained, reducing the resistance loss of the entire equipment, thereby obtaining a smaller energy consumption ratio.

[0071] Also preferably, the cross-sectional area of ​​the outlet 103 is greater than twice the cross-sectional area of ​​the air inlet 2201 .

[0072] Furthermore, the outer wall of the silencer plate of each resistive plate type silencer is wrapped with a sound-absorbing material, and the sound-absorbing material is implemented as a sound-absorbing material with a high sound absorption coefficient and a hydrophobic property.

[0073] Preferably, the gas-liquid separation device further includes a guide pipe 40 , wherein the guide pipe 40 is arranged to be connected to the outlet 103 .

The advantages of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
