Description

Technical Field

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

[0002] 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 separation device can effectively separate the gas and liquid for further processing or recovery of the substances therein. In the gas-liquid separation device, the gravity separator is usually used to separate the gas and liquid, mainly using the 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] In the chemical production process, conventional gas-liquid separators make it difficult to evenly disperse the gas-liquid mixed phase after entering the separator due to the inertia of the fluid and the different flow characteristics of gas and liquid. The contact area of ​​the inner wall of the separator is limited, and the droplets and droplets 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 will affect the subsequent gas phase engineering applications and even cause safety hazards. Utility Model Content

[0004] The purpose of the utility model is to provide a gas-liquid separation device 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 separation device, comprising: a separator body, an air inlet is opened on one side of the separator body, a baffle with a plurality of holes is arranged in the separator body, the baffle comprises a first baffle, and an overflow weir is arranged at one end of the first baffle.

[0006] Preferably, the first baffle is detachably mounted in the separator body by bolts.

[0007] Preferably, a plurality of the first baffles are arranged above the air inlet.

[0008] Preferably, a plurality of the first baffles are arranged in a staggered manner.

[0009] Preferably, the holes are micropores.

[0010] Preferably, the baffle further includes a second baffle, and a plurality of the second baffles are arranged below the air inlet.

[0011] Preferably, a plurality of the second baffles are arranged in a staggered manner.

[0012] Preferably, the second baffle is detachably mounted in the separator body by bolts.

[0013] Preferably, the top of the separator body is a curved surface structure.

[0014] Preferably, an exhaust port is opened at the top of the separator body.

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

[0016] In this gas-liquid separation device, due to the different specific gravities of the gas phase and the liquid phase, when the gas-liquid mixed phase entering from the air inlet flows in the separator body, it is blocked by the baffle plate, and the gas phase will be deflected away, while the liquid phase will maintain its motion trajectory due to inertia. The liquid phase maintaining the motion trajectory adheres to the inner wall of the separator body and converges downward under gravity. The multiple baffles arranged in the separator body cause the gas-liquid mixed phase to impact multiple times, and the liquid phase is separated from the gas phase. The baffle plates with holes filter the liquid phase and allow the gas phase to pass through, thereby further increasing the separation effect. The overflow weir at the end of the first baffle plate can also increase the residence time of the liquid phase, so that the gas phase can be separated from the liquid phase, thereby increasing the separation effect of the gas-liquid mixed phase and improving the safety of the separated gas phase in subsequent engineering applications.

[0020] 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.

[0021] like Figure 1-Figure 2 As shown, the utility model provides an embodiment of a gas-liquid separation device, including: a separator body 1, the top of the separator body 1 is a curved surface structure, and an exhaust port 3 is opened on the top of the separator body 1, and an air inlet 2 is opened on one side. The gas-liquid mixed phase enters the separator body 1 through the air inlet 2 for gas-liquid separation, and the finally separated gas phase is discharged outward from the exhaust port 3, and the liquid phase is stored in the separator body 1.

[0022] A baffle with a plurality of holes is arranged in the separator body 1. The holes are micropores. The pore diameters of the micropores are designed according to the type of liquid medium, so that liquid molecules are difficult to flow out of the micropores, but gas molecules can pass through.

[0023] Specifically, the baffle includes a first baffle 4 and a second baffle 6, both of which are detachably installed in the separator body 1 by bolts, and several first baffles 4 are staggered above the air inlet 2, and several second baffles 6 are staggered below the air inlet 2.

[0024] In this embodiment, due to the different specific gravities of the gas phase and the liquid phase, when the gas-liquid mixed phase entering from the air inlet 2 flows in the separator body 1, it is blocked by the baffle plate, and the gas phase will be deflected away, while the liquid phase will maintain its motion trajectory due to inertia. The liquid phase maintaining its motion trajectory adheres to the inner wall of the separator body 1 and gathers downward under gravity.

[0025] Specifically, the multiple baffles arranged in the separator body 1 cause the gas-liquid mixed phase to impact multiple times, and the liquid phase is separated from the gas phase. The baffles with holes are used to filter the liquid phase and allow the gas phase to pass through, thereby further increasing the separation effect.

[0026] Furthermore, an overflow weir 5 is provided at one end of the first baffle 4. The presence of the overflow weir 5 can form a higher liquid level on the first baffle 4, thereby increasing the residence time of the liquid phase and allowing the gas phase to be separated from the liquid phase. The overflow weir 5 can also change the flow pattern of the gas-liquid mixture, causing the gas phase and the liquid phase to have more contact and collision on the first baffle 4, thereby promoting the sedimentation and separation process. The longer residence time of the liquid phase allows the droplets therein to have more opportunities to contact with the droplets in the gas phase and condense into larger droplets, which is ultimately beneficial to the sedimentation and separation of the liquid phase. At the same time, the second baffle 6 below the air inlet 2 can increase the flow time of the liquid phase, allowing the liquid phase dissolved therein to be separated, thereby increasing the separation effect of the gas-liquid mixed phase and improving the safety of the separated gas phase in subsequent engineering applications.

[0027] Working principle: When the gas-liquid mixed phase entering from the air inlet 2 flows in the separator body 1, it is blocked by the baffle, and the gas phase will be deflected, while the liquid phase will maintain its motion trajectory due to inertia. The liquid phase maintaining the motion trajectory adheres to the inner wall of the separator body 1 and gathers downward under gravity. Multiple baffles cause the gas-liquid mixed phase to impact multiple times, and the liquid phase is separated from the gas phase. The baffle with holes filters the liquid phase to allow the gas phase to pass through, and the liquid phase drips downward from the side of the baffle, and the gas phase moves toward the exhaust port 3. The overflow weir 5 set at one end of the first baffle 4 can form a higher liquid level on the first baffle 4, thereby increasing the residence time of the liquid phase, so that the gas phase can be separated from the liquid phase. The second baffle 6 below the air inlet 2 can increase the flow time of the liquid phase, separate the liquid phase dissolved therein, and finally the separated gas phase is discharged outward from the exhaust port 3, and the liquid phase is stored in the separator body 1.

[0028] 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.
