Description

Technical Field

[0001] The utility model relates to the technical field of gas-liquid separators, in particular to a gas-liquid separator. Background Art

[0002] A gas-liquid separator is a device used to effectively separate gas and liquid. In industrial and chemical processes, there are usually bubbles or tiny gas particles suspended in the liquid in the gas-liquid mixture, which need to be separated. The gas-liquid separator is designed to effectively separate the gas and liquid for further processing or recovery of the substances therein. Among the gas-liquid separators, gravity separators are usually used to separate gas and liquid, mainly using gravity to make the bubbles settle or float in the liquid, and finally forming two layers of gas phase and liquid phase, thereby achieving effective separation of gas and liquid.

[0003] Conventional gas-liquid separators are used in chemical production processes. Since the gas-liquid mixed phase enters the separator with changes in speed and direction, it is difficult to quickly and evenly disperse it into the gas-liquid separator in a short time. The contact area of ​​the inner wall of the separator is limited, and the liquid phase and the gas phase cannot be completely settled and separated. As a result, there is still a large amount of liquid phase after the gas phase is discharged from the gas-liquid separator, which affects the subsequent engineering application of the gas. Utility Model Content

[0004] The purpose of the utility model is to provide a gas-liquid separator to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a gas-liquid separator, comprising: a separator body, a filter cartridge and a vertical spiral plate are arranged in the separator body, the spiral plate is wound around the lower part of the filter cartridge, a baffle is arranged under the spiral plate, and a plurality of holes are opened in the baffle.

[0006] Preferably, the filter cartridge is detachably mounted in the separator body by bolts.

[0007] Preferably, the spiral plate is fan-shaped, and the arc-shaped end is close to the inner wall of the separator body.

[0008] Preferably, the top of the separator body is configured as a curved surface, and an exhaust port is provided at the center of the curved surface.

[0009] Preferably, the filter cartridge is located directly below the exhaust port.

[0010] Preferably, an air inlet is opened on one side of the separator body.

[0011] Preferably, the baffle is arranged below the air inlet.

[0012] Preferably, the baffle is a planar plate-shaped structure and is fixed inside the separator body.

[0013] Preferably, the baffle is a funnel-shaped conical structure and is fixed in the separator body.

[0014] Preferably, the baffle is made of stainless steel.

[0015] The gas-liquid separator has the following beneficial effects:

[0016] In the gas-liquid separator, after the gas-liquid mixed phase enters the separator body, it impacts the inner wall of the separator body, the gas phase moves upward, and the liquid phase condenses downward due to gravity sedimentation, but gravity sedimentation cannot completely separate the liquid phase. A part of the liquid phase is mixed in the gas phase and moves upward until it collides with the spiral plate. After the collision, the droplets are dispersed into smaller but more numerous droplets. The small droplets are mixed in the gas phase and diffused around, thereby increasing the contact area with the filter cartridge and improving the separation effect. At the same time, a part of the liquid phase dissolves part of the gas phase during polymerization and sedimentation. The baffle can increase the residence time of the liquid phase, so that the gas phase can be separated from the liquid phase, further improving the separation effect, thereby making the discharged gas drier and more suitable for subsequent engineering applications of the gas.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 As shown, the utility model provides an embodiment of a gas-liquid separator, comprising: a separator body 1, an air inlet 11 is opened on one side of the separator body 1, the top of the separator body 1 is set as an arc surface, and an exhaust port 12 is opened at the center of the arc surface.

[0026] Specifically, Figure 2 As shown, a filter cartridge 3 made of a filter screen and a vertical spiral plate 2 are arranged in the separator body 1. The filter cartridge 3 is detachably installed in the separator body 1 by bolts and is located directly below the exhaust port 12, so that the gas phase separated by the filter cartridge 3 can be quickly and concentratedly discharged from the exhaust port 12.

[0027] Among them, the spiral plate 2 is wound around the lower part of the filter cartridge 3, and the spiral plate 2 is fan-shaped, and the arc-shaped end is close to the inner wall of the separator body 1, so that the liquid phase separated after the gas-liquid mixed phase collides with the separator body 1 rotates to the arc-shaped end of the spiral plate 2 under the action of the impact force, and drips downward along the arc-shaped trajectory of the arc-shaped end, thereby preventing the separated liquid phase from dissolving more gas phase due to high-speed movement.

[0028] Furthermore, a baffle 4 made of stainless steel is arranged below the spiral plate 2 . The baffle 4 is arranged below the air inlet 11 . The baffle 4 has a plurality of holes. The baffle 4 is a planar plate-like structure and is fixed in the separator body 1 .

[0029] In this embodiment, the gas-liquid mixed phase enters the separator body 1 from the air inlet 11 and impacts the inner wall of the separator body 1. The gas phase moves upward, and the liquid phase condenses downward due to gravity sedimentation. However, gravity sedimentation cannot completely separate the liquid phase. A part of the liquid phase is mixed in the gas phase and moves upward until it collides with the spiral plate 2.

[0030] like Figure 2-Figure 4 As shown, after the collision, the droplets are dispersed into smaller droplets with larger numbers. The small droplets are mixed in the gas phase and diffused around. After being filtered by the filter cartridge 3, the small droplets are separated from the gas phase and drip downward along the outer surface of the filter cartridge 3. The gas phase that passes through the filter cartridge 3 is discharged outward from the exhaust port 12. The spiral plate 2 can increase the contact area between the mixed liquid phase in the gas phase and the filter cartridge 3 through collision, thereby improving the separation effect.

[0031] like Figure 5-Figure 6As shown, a part of the liquid phase dissolves a part of the gas phase during polymerization and sedimentation. The baffle 4 can increase the residence time of the liquid phase, so that the liquid phase collides with the baffle 4 to form more small droplets with smaller volume and larger number. After the collision, the gas phase attached to the liquid phase separates from the droplets and moves upward, and the liquid phase flows downward through the holes on the baffle 4, further improving the separation effect, thereby making the discharged gas drier and more suitable for subsequent engineering applications of the gas.

[0032] In another embodiment, the baffle 4 is a funnel-shaped conical structure and is fixed in the separator body 1 , so that the liquid phase can pass through the baffle 4 more quickly.

[0033] Working principle: After the gas-liquid mixed phase enters the separator body 1 from the air inlet 11, it impacts the inner wall of the separator body 1, the gas phase moves upward, and the liquid phase condenses downward due to gravity sedimentation, but gravity sedimentation cannot completely separate the liquid phase. A part of the liquid phase is mixed in the gas phase and moves upward until it collides with the spiral plate 2. After the collision, the droplets are dispersed into smaller but more numerous droplets. The small droplets are mixed in the gas phase and diffuse around. After being filtered by the filter cartridge 3, the small droplets are separated from the gas phase and drip downward along the outer surface of the filter cartridge 3. The gas phase that passes through the filter cartridge 3 is discharged outward from the exhaust port 12. At the same time, a part of the liquid phase dissolves part of the gas phase during polymerization and sedimentation. The baffle 4 can increase the residence time of the liquid phase, so that more smaller droplets are formed after the liquid phase collides with the baffle 4. After the collision, the gas phase attached to the liquid phase separates from the droplets and moves upward, and the liquid phase flows downward through the holes on the baffle 4.

[0034] In summary, although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
