Description

Technical Field

[0001] The present invention relates to the technical field of gas-liquid separation equipment, in particular to an enhanced gas-liquid separator for zero emission. Background Art

[0002] The gas-liquid separator is used to process gas containing a small amount of condensate, achieve gas-liquid separation, and help condensate recovery and gas purification. Its basic principle is:

[0003] 1. Taking advantage of the difference in specific gravity between gas and liquid, in a suddenly expanded container, when the flow rate decreases and the flow direction changes, the tiny liquid droplets in the gas phase sink and separate from the gas;

[0004] 2. Using cyclone separation, tiny droplets in the gas phase are thrown onto the wall by high-speed airflow, and after collision, they lose kinetic energy and separate from the turning gas;

[0005] 3. Through the fine mesh, the collision and contact between the droplets and the mesh are increased to intercept the droplets and achieve gas-liquid separation.

[0006] In the existing technology, commonly used gas-liquid separators are all simple baffled type, inertial motion or wire mesh type. Although they can achieve certain effects, they have poor adaptability and are designed for single-quality gas-liquid separation. When starting and stopping or operating conditions are unstable, especially when the diameter of droplets in the gas constantly changes, the gas-liquid separator cannot cope with it, and the discharged gas is mixed with more liquid, resulting in the gas-liquid separation effect often not meeting the requirements.

[0007] Therefore, how to make the gas-liquid separator able to filter liquids of different particle sizes and be more adaptable under different working conditions to ensure the gas-liquid separation effect has become a technical problem that technicians in this technical field urgently need to solve. Summary of the Invention

[0011] A liquid storage area is provided at the bottom of the device body for storing and discharging liquid;

[0012] A gas inlet is provided on one side of the equipment body corresponding to the position of the spiral guide vane; and the bottom end of the central tube extends out of the equipment body and is provided as a gas outlet.

[0013] Preferably, the liquid storage area is equipped with a drain, a liquid level controller and an automatic valve;

[0014] The liquid level controller controls the automatic valve switch to enable the drain outlet to drain or stop draining.

[0015] Preferably, a gas sampling port is provided on the gas inlet and the gas outlet respectively.

[0016] Preferably, the central pipe is composed of two pipe sections, an upper pipe section and a lower pipe section, and the spiral guide vanes, the vertical guide vanes and the wire mesh demister are all arranged on the upper pipe section;

[0017] The equipment body is composed of two upper and lower structural sections, and the connection between the two structural sections is connected through an equipment flange.

[0018] Preferably, the equipment body is provided with a manhole inspection port at a position corresponding to the wire mesh demister.

[0019] Beneficial effects of the present invention:

[0020] Due to the above-mentioned structural design, the present invention can effectively separate droplets of different particle sizes contained in the gas through the cooperation of spiral guide blades, vertical guide blades and wire mesh demisters, is suitable for different working conditions, achieves more thorough gas-liquid separation, and ensures the effect of gas-liquid separation.

DETAILED DESCRIPTION

[0025] The concept, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings to fully understand the purpose, characteristics and effects of the present invention.

[0026] Example:

[0027] like Figure 1-Figure 2 As shown, the enhanced gas-liquid separator for zero emission includes an equipment body 1, a central tube 2 is provided inside the equipment body 1, and spiral guide blades 3, vertical guide blades 4 and a wire mesh demister 5 are provided on the outside of the central tube 2 in sequence from bottom to top.

[0028] There are multiple vertical guide blades 4 , which are evenly spaced around the central tube 2 , and the outer periphery of the wire mesh demister 5 extends to the inner wall of the equipment body 1 .

[0029] A liquid storage area 6 is provided at the bottom of the device body 1 for storing and discharging liquid.

[0030] A gas inlet 7 is provided on one side of the device body 1 corresponding to the position of the spiral guide vane 3 ; the bottom end of the central tube 2 extends out of the device body 1 and is provided as a gas outlet 8 .

[0031] The main innovation of the present invention is that by providing the spiral guide blades 3, the vertical guide blades 4 and the wire mesh demister 5, liquids of different particle sizes in the gas can be filtered to achieve more thorough gas-liquid separation.

[0032] More specifically, spiral guide blades 3 are provided to force the gas to perform a spiral motion inside the device body 1. Meanwhile, a suitable blade spacing of the spiral guide blades 3 can increase the flow velocity of the gas in its channel, and utilize the centrifugal effect generated by the high flow velocity to separate larger droplets in the gas.

[0033] The vertical guide vanes 4 are provided to change the flow direction of the gas and reduce the flow velocity of the gas, further increasing the collision of the droplets in the flow (between the droplets, between the droplets and the inner wall of the device body 1 or the vertical guide vanes 4). At the same time, the upward flow velocity of the gas is reduced due to the enlargement of the flow channel, and the droplets in the gas sink by gravity and are separated from the gas;

[0034] A wire mesh demister 5 is provided to further remove fine droplets in the gas, thereby achieving a more thorough gas-liquid separation. The gas changes direction at the top of the equipment body 1 and is discharged downwardly along the central tube 2. The change of direction of the gas at the top is beneficial to preventing the liquid accumulated on the wire mesh demister 5 from being directly carried out of the equipment body 1 by the gas.

[0035] Furthermore, there is a certain gap between the spiral guide blades 3 and the vertical guide blades 4 and the equipment body 1, which is conducive to the liquid flowing down to the bottom along the inner wall of the equipment body 1 after hitting the wall.

[0036] The liquid storage area 6 is equipped with a drain port 9, a liquid level controller 10 and an automatic valve 11; the liquid level controller 10 can control the switch of the automatic valve 11. When the liquid level is high, the liquid level controller 10 controls the automatic valve 11 to open and drain water through the drain port 9. When the liquid level is low, the liquid level controller 10 controls the automatic valve 11 to close and stop draining water through the drain port 9, which is beneficial to maintaining the sealing performance inside the equipment body 1 and preventing the internal gas of the equipment body 1 from being connected to the outside and leaking or external media from entering the equipment.

[0037] In some embodiments, a gas sampling port 12 is provided on the gas inlet 7 and the gas outlet 8, respectively. The gas sampling of the gas inlet 7 and the gas outlet 8 can be conducted for comparative analysis to detect the gas-liquid separation effect of the equipment body 1. At the same time, it can be detected whether the gas discharged from the gas outlet 8 meets the requirements of subsequent processes (such as recovery, discharge, etc.).

[0038] In other embodiments, in order to facilitate maintenance of the interior of the equipment body 1, the central pipe 2 consists of two pipe sections, an upper pipe section and a lower pipe section, and the spiral guide blades 3, the vertical guide blades 4 and the wire mesh demister 5 are all arranged on the upper pipe section; the lower pipe section is fixed to the inner wall of the equipment body 1 by a fixing device 15, and the equipment body 1 consists of two upper and lower structural sections. The connection between the two structural sections is located at the upper part of the connection between the two pipe sections of the central pipe 2 and is connected through the equipment flange 13; installation, inspection and maintenance can be carried out by opening the equipment flange 13.

[0039] In other embodiments, in order to facilitate the installation, inspection and maintenance of the wire mesh demister 5 , manhole inspection openings 14 are respectively provided at the upper and lower positions of the equipment body 1 corresponding to the wire mesh demister 5 .

[0040] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art through logical analysis, reasoning, or limited experimentation based on the concepts of the present invention and the prior art should be within the scope of protection defined by the claims.
