Description

Technical Field

[0001] The invention relates to a gas-liquid separator and a method, belonging to the technical field of gas-liquid separation. Background Art

[0002] A gas-liquid separator is a separation device that separates liquid droplets from an airflow. Gas-liquid separators are widely used in petroleum, chemical, diesel hydrogenation tail gas recovery, natural gas extraction, storage and transportation, deep processing, flue gas waste heat utilization, wet desulfurization, wet dust removal, fermentation engineering and other process. The corrugated plate separator is widely used in actual industrial production due to its convenient production, high gas-liquid separation efficiency, and small footprint. The corrugated plate gas-liquid separator is usually composed of multiple corrugated plates, allowing the airflow with entrained droplets to flow in the tortuous channel formed by multiple corrugated plates. Due to the effect of inertia, the movement direction of the droplets is difficult to change with the change of the movement direction of the airflow. Finally, under the action of inertia, the droplets break away from the trajectory of the airflow and collide with the wall of the corrugated plate. As the droplets accumulate, a liquid film is eventually formed on the corrugated plate and discharged from the corrugated plate through the water collection channel. The wire mesh gas-liquid separator is a highly efficient gas-liquid separation device, which is mainly used to separate droplets with a diameter greater than 5μm in the gas. When the droplets pass through the filter layer with the airflow, the filter layer wire mesh grid hinders the airflow, causing the airflow to change its speed and direction of movement infinitely and bypass the wire mesh. These changes cause the droplets to produce inertial impact, gravity sedimentation, interception, Brownian diffusion, electrostatic attraction and other effects on the filter layer mesh, causing the droplet particles to aggregate and separate.

[0003] However, the corrugated plate gas-liquid separator also has its own disadvantages. When the number of corrugated plates reaches a certain level, the airflow may not be able to reach the corrugated plate channel far away from the airflow inlet, resulting in redundant structure; and the droplets separated from the airflow and captured by the wall can only flow out of the corrugated plate along the water collection channel under the action of their own gravity. If the position of the corrugated plate is not arranged reasonably, the droplets may not flow out of the corrugated plate in time and eventually separate from the liquid film or break under the action of the airflow, resulting in a decrease in separation efficiency; after the droplets are discharged along the wall, if the droplets gather in the water collection pool for a long time, the droplets may remix with the airflow after evaporation, resulting in a decrease in separation efficiency.

[0004] Therefore, it is urgent to propose a cyclonic corrugated plate-wire mesh gas-liquid separator and method to solve the above technical problems. Summary of the invention

The sewage outlet 1, the overflow port 15, the upper liquid level gauge port 5, and the lower liquid level gauge port 6 are all connected to the water collection tank 13. A manhole 2 and a separation space pressure measuring hole 12 are provided in the middle of the separator cylinder 7. The separation space pressure measuring hole 12 is connected to the separation space. An inlet space pressure measuring hole 4 is provided at the upper part of the separator cylinder 7. The inlet space pressure measuring hole 4 is connected to the inlet space. Pressure sensors are provided at the separation space pressure measuring hole 12 and the inlet space pressure measuring hole 4; the upper hole 5 of the liquid level gauge is used to install the liquid level gauge to detect the liquid level height to prevent the liquid level height from being too high and affecting the separation efficiency of the equipment;

[0037] It also includes a central fixing member 8, which is cylindrical, and has a hemispherical top cover on the upper part of the cylinder, which is conducive to uniform dispersion of gas and liquid and prevents accumulation of droplets. One end of the corrugated plate 9 is connected to the central fixing member 8, and the other end of the corrugated plate 9 is connected to the inner wall of the cylindrical separator cylinder 7. The vertical length of the central fixing member 8 is greater than the vertical length of the corrugated plate 9. The circular tube gas-liquid inlet 3, the separator cylinder 7, the central fixing member 8, the circular plate baffle 10, the wire mesh separator 11, and the circular tube gas outlet 14 are coaxially arranged;

[0038] The angle between the corrugated plate 9 and the horizontal direction is α=5°, and the angle between the corrugated plate 9 and the central axis is β=20°, forming a corrugated plate group with a high edge bottom in the middle. The inclined arrangement is conducive to increasing the collision wall surface and improving the utilization rate of each corrugated plate 9, thereby reducing the number of corrugated plates used; in order to enable the droplets to be discharged from the corrugated plate channel in time after being captured, the present invention arranges the corrugated plates in the gas-liquid separator in a spiral manner, so that the separated droplets can be discharged from the corrugated plate channel in time under the action of gravity and inertia, and the gas will have one more bend on the wall of the separator cylinder 7, which can further improve the separation efficiency; through calculation, it is found that when the airflow direction and the blade corrugated plate direction form a certain angle, while ensuring the separation efficiency, the pressure drop of the airflow can be effectively reduced, thereby achieving the purpose of reducing energy consumption, each wave node presents an angle of 5° with the horizontal direction, and the connection between the wave node and the central cylinder is higher than the connection between the wave node and the cylinder, which is more conducive to the captured droplets flowing to the cylinder wall and converging at the bottom;

[0039] The corrugated plate 9 includes a first fin 91, a main plate 92 and a second fin 93. The main plate 92 is a sawtooth corrugated plate.

A tortuous channel is formed between adjacent corrugated plates 9. The opening is parallel to the channel at the corresponding position. The sawtooth / zigzag corrugated plate 9 used in the present invention is conducive to the rapid separation of gas and liquid droplets with large density differences by inertia. The process is simple and is conducive to cost control.

[0040] A first air hole 921 is processed on the upper side of the first wave valley on the front side of the first wave node of one main board 92, and a second air hole 922 is processed on the lower side of the first wave valley on the back side of the first wave node of another adjacent main board 92, so that the first air hole 921 and the second air hole 922 are arranged alternately, and the first air hole 921 and the second air hole 922 are through holes; after calculation, it is found that particles will gather at the first wave node of the corrugated plate to form a liquid film, and the generation of the liquid film will reduce the separation efficiency of the corrugated plate, so holes are opened on the upper and lower plates of the first wave node, and the liquid film will flow to the back of the corrugated plate under the action of the gas phase, thereby reducing the thickness of the liquid film and improving the separation efficiency. While ensuring that the sawtooth / folded line corrugated plate 9 is suitable for large flow and high flow rate, it also solves the problem of accumulation and blockage caused by flow turbulence;

One end of the corrugated plate 9 is connected to the central fixing member 8, and the other end of the corrugated plate 9 is connected to the inner wall of the cylindrical separator cylinder 7. The circular tube gas-liquid inlet 3, the separator cylinder 7, the central fixing member 8, the circular plate baffle 10, the wire mesh separator 11, and the circular tube gas outlet 14 are coaxially arranged;

[0045] The angle between the corrugated plate 9 and the horizontal direction is α=5°, and the angle between the corrugated plate 9 and the central axis is β=20°;

[0046] The corrugated plate 9 includes a first fin 91, a main plate 92 and a second fin 93. The main plate 92 is a sawtooth corrugated plate. The second fin 93 is arranged at the crest of the sawtooth corrugated plate. The first fin 91 is arranged at the trough of the sawtooth corrugated plate.

[0047] A first air hole 921 is processed on the front side of the first wave node of one main board 92, and a second air hole 922 is processed on the back side of the first wave node of another adjacent main board 92;

[0048] The bottom of the cylinder 7 includes an annular plate 71 and a reducer 72. The inner side of the annular plate 71 is connected to the bottom of the reducer 72, and the outer side of the annular plate 71 is connected to the bottom end of the cylinder 7. The reducer 72, the annular plate 71, and the cylinder 7 are connected in sequence to form a water collecting pool 13. The reducer 72 arranged at the lower part of the inner cavity of the separator cylinder 7 is a circular tube with a narrow upper part and a wide lower part.

The middle part of the inner cavity of the separator cylinder 7 is a separation space, and the upper part of the inner cavity of the separator cylinder 7 is an inlet space.

[0049] The wire mesh separator 11 is a round tube that is wide at the top and narrow at the bottom. A baffle 10 and a gas outlet 14 are respectively provided at the upper and lower ends of the wire mesh separator 11. The diameter of the baffle 10 is greater than or equal to the upper diameter of the wire mesh separator 11, the diameter of the baffle 10 is greater than the upper diameter of the reducer 72, and the diameter of the baffle 10 is less than the lower diameter of the reducer 72.

[0050] The method comprises the following steps:

[0051] Step 1: Input air flow: The air flow containing liquid droplets enters the device from the air-liquid inlet 3, and the air flow encounters the upper part of the central fixing member 8 and changes its flow direction;

[0052] Step 2: Cyclone separation: When the airflow passes through the tortuous channel formed between adjacent corrugated plates 9, due to the effect of inertia, the movement direction of the droplets is difficult to change with the change of the movement direction of the airflow. The slope β makes the gas pass through the corrugated plate 9 and become a cyclone. Under the action of centrifugal force, the droplets break away from the movement trajectory of the airflow and collide with the wall surface of the corrugated plate 9 (including the main plate and the fin wall surface) and are separated. Under the combined action of adhesion and gravity, the droplets are collected along the slope α of the first fin 91 and the second fin 93 of the corrugated plate 9 to the wall surface of the inner cavity of the separator cylinder 7. The setting of the slope α not only solves the problem of water accumulation on the fins when performing gas-liquid separation from top to bottom, but also prevents the separated gas and liquid from mixing again due to convection, thereby greatly improving the separation efficiency.

[0053] Step 3: Gas-liquid discharge: Liquid droplets flow out from the corrugated plate, and under the action of gravity, continue to flow along the middle wall of the separator cylinder 7 through the baffle 10 to the water collection pool 13, and finally discharge from the separator through the sewage outlet 1. During the falling process of water droplets, surface tension will make the water droplets fit closely with the wall surface, forming a stable contact interface, so that the water droplets will no longer mix with the airflow. At the same time, gravity and the airflow formed by the downward dry gas act together on the water droplets on the wall, accelerating their falling speed and improving the separation efficiency. The dry gas enters the middle of the separator cylinder 7 after being filtered by the corrugated plate 9, and passes through the narrow gap between the baffle 10 and the separator cylinder 7, which increases the airflow speed and hits the wire mesh separator. The droplets on the separator 11 are quickly separated from the wire mesh separator 11. At the same time, the design of the wire mesh separator 11 also prevents the accumulation of droplets, which is conducive to the droplets flowing into the water collection tank 13 under the action of gravity. The gas is filtered through the wire mesh separator 11, and finally the dry gas that has undergone two droplet separation treatments is obtained through the gas outlet 14; the baffle 10 not only divides the interior of the separator cylinder 7 into two parts, the separation space and the water collection tank 13, to prevent the collected droplets in the water collection tank 13 from evaporating and entering the dry gas channel 7 again to affect the separation efficiency, but also changes the gas flow direction. At the same time, a baffle 10 is added at the upper end of the gas outlet 14 to prevent the droplets from affecting the separation efficiency;

[0054] The inlet space pressure measuring hole 4 and the separation space pressure measuring hole 12 are used to monitor the pressure in real time to prevent excessive pressure from affecting the gas-liquid flow direction in step three;

[0055] The drain valve of the drain port 1 and the overflow valve of the overflow port 15 can both adopt a one-way valve. When the drain port 1 is blocked or the discharge is not timely, the liquid level is observed in real time using the liquid level gauges of the upper liquid level gauge port 5 and the lower liquid level gauge port 6, which is convenient for finding problems and timely maintenance. When the upper liquid level gauge port 5 fails, the liquid can be discharged in time through the overflow port 15. The problems that may arise during use are fully considered, and a reasonable design layout is carried out to improve the separation efficiency and facilitate maintenance;

[0056] The droplet separation efficiency is calculated by the ratio of the inlet and outlet droplet masses. The specific formula is as follows:

[0057]

[0058] Where: η is the separation efficiency of the separator, %; m e is the mass flow rate of the droplets at the inlet; m l is the mass flow rate of the droplets at the outlet; w i η i It is the separation efficiency of droplets with a certain diameter.

Therefore, the present invention will no longer describe the technical solutions after arrangement and combination one by one, but it should be understood that the technical solutions after arrangement and combination have been disclosed by the present invention.
