Description

Technical Field

[0001] This utility model relates to the technical field of gas-liquid separation devices, and in particular to a material gas-liquid separation device. Background Technology

[0002] The material in the thin-film evaporator is the product of the transesterification reaction. The raw materials for the transesterification reaction are amyl acetate, methanol, and sodium methoxide, and the products are methyl acetate, 2-pentanol, and 3-pentanol. At the same time, there is also a side reaction, in which sodium methoxide reacts with acetic acid to produce methanol and sodium acetate. As the thin-film evaporator operates, the material that enters the evaporator in liquid form evaporates into a gas phase and enters a gas-liquid separator to separate the liquid phase and salts mixed in with the gas phase. If these are not separated, the salts will deposit in the pipelines of subsequent equipment, causing blockage of pump filters. Therefore, a gas-liquid separator is required for separation.

[0003] In practical applications, existing gas-liquid separation devices have relatively complete structures and functions, which can meet basic usage requirements. However, the following problems still exist:

[0004] In actual use, after the gas-liquid separator passes through the internal separation tank, the liquid inside the gas will adhere to the tank due to cooling. However, if the gas flow rate is too fast, it is easy to cause incomplete cooling, which in turn leads to incomplete filtration of the liquid inside the gas, leaving a large amount of liquid. The liquid accumulates in the separation tank and needs to be collected and poured back into the evaporator. The operation steps include collection, transfer and pouring, which is a complicated process.

[0005] Therefore, this utility model provides a material gas-liquid separation device. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a material gas-liquid separation device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a material gas-liquid separation device, comprising an evaporator, wherein a discharge pipe is provided at the top of the evaporator and a feed pipe is provided on one side of the evaporator; a gas-liquid separation structure is provided at one end of the discharge pipe, the gas-liquid separation structure comprising a separation tank, a first connecting pipe is provided on one side of the separation tank, and a second connecting pipe is provided on the side of the separation tank opposite to the first connecting pipe; an auxiliary maintenance structure is provided on one side of the separation tank, the auxiliary maintenance structure comprising a rectangular maintenance frame, the rectangular maintenance frame being fixedly connected to one side of the separation tank.

[0008] In a preferred embodiment, a first flange is fixedly connected to one end of the first connecting pipe, a second flange is fixedly connected to one end of the discharge pipe, a first threaded clamp is threadedly connected to the inner wall of the second flange, a threaded clamping hole is provided on the inner wall of the first flange, a circular plate is fixedly connected to the inner wall of the separation tank, a hollow guide tube is fixedly connected to the inner wall of the circular plate, a spiral blade is fixedly connected to the outer surface of the hollow guide tube, the first connecting pipe communicates with the lower part of the circular plate, the second connecting pipe communicates with the upper part of the circular plate, a filter circular plate is fixedly connected to the inner wall of the separation tank, an auxiliary guide tube is fixedly connected to the bottom of the separation tank, and one end of the auxiliary guide tube is fixedly connected to the feed pipe.

[0009] The technical effect of adopting the above-mentioned further solution is that, under the action of the hollow conduit and the spiral blade, the mixed gas flowing into the separator will be guided to the bottom of the hollow conduit by the spiral blade, and then flow from the bottom to the top of the hollow conduit, thereby making the mixed gas stay in the separator for a longer time, and making the cooling and filtration more thorough.

[0010] In a preferred embodiment, a rectangular insert is snapped into the inner wall of the rectangular maintenance frame, and a baffle is fixedly connected to one side of the rectangular insert.

[0011] The technical effect of adopting the above-mentioned further solution is that the rectangular insert can block the rectangular maintenance frame during separation, and the filter disc will filter the salt substances. At this time, the salt solid particles adhering to the top of the filter disc can be collected through the rectangular maintenance frame.

[0012] In a preferred embodiment, the inner wall of the rectangular maintenance frame is provided with a first screw hole, and the top of the rectangular insert is provided with a second screw hole. The inner walls of the first screw hole and the second screw hole are threadedly connected with a second threaded rod.

[0013] The technical effect of adopting the above-mentioned further solution is that the second threaded rod can be fixed in conjunction with the first and second threaded holes, thereby providing auxiliary fixation for the rectangular maintenance frame and the rectangular insert.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] By setting up a gas-liquid separation structure, the residence time of the mixed gas entering the separator is increased through the hollow conduit and spiral vanes, allowing for thorough cooling and separation. This results in a more complete separation of liquid and gas, improving gas purity. Simultaneously, it filters out salt particles within the liquid. The liquid can also flow back to the evaporator through an auxiliary conduit for easy recycling. An auxiliary maintenance structure, with a rectangular maintenance frame, helps collect salt particles from the internal filter discs, sweeping them out of the separator. When not in use, the rectangular maintenance frame can be sealed with rectangular inserts. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4As shown, this embodiment provides a technical solution: a material gas-liquid separation device, including an evaporator 1, a discharge pipe 2 at the top of the evaporator 1, and a feed pipe 3 on one side of the evaporator 1; a gas-liquid separation structure 4 is provided at one end of the discharge pipe 2, the gas-liquid separation structure 4 includes a separation tank 41, a first connecting pipe 46 is provided on one side of the separation tank 41, and a second connecting pipe 45 is provided on the side of the separation tank 41 opposite to the first connecting pipe 46; an auxiliary maintenance structure 5 is provided on one side of the separation tank 41, the auxiliary maintenance structure 5 includes a rectangular maintenance frame 51, the rectangular maintenance frame 51 is fixedly connected to one side of the separation tank 41, by setting the gas-liquid separation structure 4, in the hollow conduit 43 and the spiral... Under the action of plate 44, the residence time of the mixed gas entering the separator 41 is increased, which allows for sufficient cooling and separation, making the separation of liquid and gas more thorough and improving the purity of the gas. At the same time, it can filter salt particles inside the liquid. The liquid can also flow back to the evaporator 1 through the auxiliary conduit 411 for easy recycling. By setting the auxiliary maintenance structure 5, the rectangular maintenance frame 51 can assist in collecting salt particles on the internal filter disc 412 and sweep them out of the separator 41. When not in use, the rectangular maintenance frame 51 can be sealed by the rectangular insert 52.

[0024] Going a step further, such as Figures 2-4 As shown: One end of the first connecting pipe 46 is fixedly connected to a first flange 47, and one end of the discharge pipe 2 is fixedly connected to a second flange 49. The inner wall of the second flange 49 is threadedly connected to a first threaded clamp 410. The inner wall of the first flange 47 has a threaded clamping hole 48. The inner wall of the separator 41 is fixedly connected to a circular plate 42. The inner wall of the circular plate 42 is fixedly connected to a hollow guide tube 43. The outer surface of the hollow guide tube 43 is fixedly connected to a spiral blade 44. The first connecting pipe 46 communicates with the lower part of the circular plate 42, and the second connecting pipe 45 communicates with the circular plate 41. The upper part of the separator 41 is connected to the filter plate 412, which is fixedly connected to the inner wall of the separator 41. The bottom of the separator 41 is fixedly connected to the auxiliary conduit 411, and one end of the auxiliary conduit 411 is fixedly connected to the feed pipe 3. Under the action of the hollow conduit 43 and the spiral blade 44, the mixed gas flowing into the separator 41 is guided to the bottom of the hollow conduit 43 by the spiral blade 44, and then flows from the bottom of the hollow conduit 43 to the top. This makes the mixed gas stay in the separator 41 for a longer time, and makes the cooling and filtration more thorough.

[0025] The above solution still has the problem of not being able to clean the salt particles filtered on the filter disc 412, such as... Figure 3As shown: In this scheme, a rectangular insert 52 is snapped into the inner wall of the rectangular maintenance frame 51. A baffle 53 is fixedly connected to one side of the rectangular insert 52. The rectangular insert 52 can block the rectangular maintenance frame 51 when separated. The filter disc 412 will filter the salt substances. At this time, the salt solid particles adhering to the top of the filter disc 412 can be collected through the rectangular maintenance frame 51.

[0026] The above solution also suffers from instability due to the frictional fixing method between the rectangular insert 52 and the rectangular maintenance frame 51. Figure 3 As shown, the inner wall of the rectangular maintenance frame 51 is provided with a first screw hole 54, and the top of the rectangular insert 52 is provided with a second screw hole 55. The inner walls of the first screw hole 54 and the second screw hole 55 are threadedly connected with a second threaded clamp 56. The second threaded clamp 56 can cooperate with the first screw hole 54 and the second screw hole 55 for fixation, thereby providing auxiliary fixation for the rectangular maintenance frame 51 and the rectangular insert 52.

[0027] Working principle:

[0028] like Figure 1-4 As shown:

[0029] In use: The first flange 47 and the second flange 49 are fitted together. At this time, the first threaded clamp 410 and the threaded clamp hole 48 are used for auxiliary fixation, thereby fixing the first connecting pipe 46 and the discharge pipe 2. At this time, the gas inside the evaporator 1 flows into the interior of the separator 41. It can be guided to the bottom of the hollow tube 43 through the spiral blade 44, and then flow upward from the bottom of the hollow tube 43, thereby separating the liquid inside the mixed gas. The second threaded clamp 56 is separated from the first screw hole 54 and the second screw hole 55, thereby separating the rectangular insert 52 from the rectangular maintenance frame 51, thereby facilitating the auxiliary cleaning of salt substances on the filter disc 412.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
