Description

Technical Field

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

[0002] Gas-liquid separators are of great significance in industrial production. In industrial and chemical processes, gas-liquid mixtures often contain bubbles or tiny gas particles suspended in the liquid, which need to be separated. Using gas-liquid separators can help protect equipment, prevent gas or liquid from entering areas where they should not exist, and extend the service life of equipment. Gas-liquid separators can also improve production efficiency, ensure product quality, and reduce failures and accidents during the production process, thereby reducing production costs and improving production benefits.

[0003] The higher the degree of dispersion of the fluid entering the separator, the more conducive it is to gas-liquid separation. In order to evenly distribute the liquid, existing separators tend to cause most of the liquid to fall from the edges of the distributor if the liquid flow rate is too high, or to fall from the center if the liquid flow rate is too low. Both situations are detrimental to even liquid distribution. Utility Model Content

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0028] Referring to Figures 1-4 An embodiment provided by the utility model: a gas-liquid separator, comprising: a shell 1; the inner side of the shell 1 is provided with a support column 2, the support column 2 is provided with a uniform distribution device 3 and a plurality of first baffles 4, and the entering gas-liquid is uniformly distributed and separated; a plurality of second baffles 5 are arranged at the inner wall of the shell 1, and the first baffles 4 and the second baffles 5 are alternately arranged in the vertical direction.

[0029] The applicant found in the research that in the gas-liquid separator, a large amount of small liquid droplets are taken away by the gas, so that a large amount of liquid is contained in the outlet gas. In the separator, the residence time of the liquid and the dispersion degree of the liquid can effectively improve the separation efficiency of the separator. Increasing the dispersion degree of the liquid in the separator generally adopts a uniform distribution device to disperse the inlet liquid of the separator, so as to effectively improve the separation efficiency. For a general separator, increasing the residence time of the liquid means that the volume of the separator needs to be increased, thereby increasing the equipment cost.

[0030] In the embodiment, the gas-liquid enters the uniform distribution device from one side of the shell 1, the liquid is uniformly distributed and separated, the liquid sequentially passes through a plurality of first baffles 4 and second baffles 5, the first baffle is provided with a threaded structure, the liquid is rotated and separated to both sides, the gas is retained in the middle, the effect of cyclone separation is achieved, the residence time of the liquid is increased, the liquid falls from the first baffle 4 to the second baffle 5, the second baffle 5 is provided with a mesh, and the liquid is uniformly distributed on the second baffle 5 again, so that the gas and the liquid are separated.

[0031] The uniform distribution device 3 comprises a uniform distributor 31, the outer side of the uniform distributor 31 is provided with an upwardly extending first overflow plate 32; the first overflow plate 32 and the inner wall of the shell 1 have a gap.

[0032] In the embodiment, the gas-liquid enters from the side of the shell 1 of the separator, firstly enters a uniform distribution device 3, and the liquid is dispersed, and the higher the dispersion degree of the liquid in the shell 1, the more favorable the separation of the gas-liquid. The uniform distributor 31 is a disc with mesh holes. After the liquid enters the uniform distribution device, part of the liquid directly flows out from the mesh holes below the uniform distributor 31. If the liquid flow is relatively large, a volume cavity is formed between the uniform distributor 31 and the first overflow plate 32, and the liquid can be stored while being uniformly distributed. Another part of the liquid can overflow from the first overflow plate 32 at the edge of the uniform distributor 31, and the overflowed liquid directly falls into the second baffle 5.

[0033] The disc height and the number of mesh holes of the uniform distributor 31 are set according to the size of the liquid flow. Preferably, the uniform distributor 31 is uniformly holed, the holed area accounts for 50% to 75% of the total area of the uniform distributor 31, and the total area of the uniform distributor accounts for 80% to 90% of the cross-sectional area of the separator.

[0034] The first baffle 4 is located above the second baffle 5; the outer diameter of the first baffle 4 is greater than the inner diameter of the second baffle 5, and the outer diameter of the uniform distributor 31 is greater than the outer diameter of the first baffle 4.

[0035] The first baffle 4 is an integral baffle or a plurality of circumferentially arranged blades. The first baffle 4 is arranged on the support column 2 and is inclined downward. The upper surface of the first baffle 4 is provided with a spiral structure, so that the liquid passing through the uniform distribution device 3 rotates. The spiral structure is a plurality of convex or concave grooves rotating in the same direction.

[0036] In the embodiment, the first baffle 4 is preferably an integral baffle. A plurality of convex spiral curves are arranged on the upper surface of the first baffle 4, so that the liquid rotates on the first baffle 4 and generates centrifugal force. On the one hand, the liquid residence time is increased, and on the other hand, the liquid is separated to both sides with the rotation, and the gas is retained in the middle. The effect of cyclone separation is achieved, so that the gas-liquid separation efficiency is higher.

[0037] The support column 2 penetrates through the second baffle 5 and has a gap with the second baffle 5. The second baffle 5 is inclined downward. The second overflow plate 6 extending upward is arranged at the inner diameter of the second baffle 5. A plurality of mesh holes are arranged on the second baffle 5, so that the liquid flows downward from the second baffle 5.

[0038] In the embodiment, the liquid falling from the first baffle 4 falls on the second baffle 5, the second baffle 5 is funnel-shaped, and a plurality of mesh holes are arranged in the middle to form a hollow structure. The liquid falling from the first baffle 4 falls on the second baffle 5, and the second baffle 5 has a second overflow plate 6 at the edge to form a volume cavity. In this way, the liquid can be uniformly distributed on the second baffle 5, the second baffle 5 can increase the flow of the liquid, thereby increasing the residence time of the liquid. In order to prevent the accumulation of liquid on the second baffle 5 due to the increase of the liquid flow, the second baffle 5 is provided with a mesh hole structure, which can effectively prevent the accumulation of liquid. In the case of a large amount of liquid, a large amount of liquid can also have a certain uniform distribution effect when flowing down from the mesh hole.

[0039] Finally, it should be noted that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. made within the spirit and principles of the utility model, should be included in the protection scope of the utility model.
