Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of carbonate production, specifically to a carbonate catalyst separation device. Background Technology
[0002] Carbonates are compounds in which the hydrogen atoms of the two hydroxyl groups (-OH) in a carbonic acid molecule are partially or completely replaced by alkyl groups (R, R'). Carbonates have wide applications in many fields. As an important organic solvent, carbonate solvents are widely used in the coatings, pharmaceuticals, pesticides, food, and cosmetics industries. In the coatings industry, they can be used as diluents and pigment acceptors, replacing traditional organic solvents and reducing environmental pollution. In the pharmaceutical and pesticide industries, carbonate solvents can be used to manufacture pharmaceuticals and pesticides, offering high safety and efficiency. In the food and cosmetics industries, carbonate solvents can be used as additives and solvents, improving the safety and quality of food and cosmetics.
[0003] In carbonate production, there are various methods for separating the catalyst from the organic carbonate. The choice of these methods often depends on the specific production process, the properties of the catalyst, and the purity requirements of the target product. Here are some common separation methods:
[0004] 1. Physical separation method
[0005] Distillation method: This method utilizes the difference in boiling points between different components. The mixture is vaporized by heating, and then the target product is collected by condensation. This method is suitable when the boiling points of the catalyst and the organic carbonate differ significantly.
[0006] Extraction method: This method utilizes the difference in solubility of different components in a mixture to extract the target product from the mixture. Choosing a suitable extractant is crucial; it should be able to efficiently separate organic carbonates from catalysts and other impurities.
[0007] Adsorption method: This method utilizes the different adsorption capacities of adsorbents (such as activated carbon, molecular sieves, etc.) for different components in a mixture to adsorb the target product or catalyst onto the adsorbent, and then separate them through desorption or elution.
[0008] 2. Chemical separation method
[0009] Chemical reaction method: In some cases, the chemical properties of catalysts or organic carbonates can be altered through chemical reactions to make them easier to separate. For example, specific chemical reagents can be added to deactivate the catalyst or convert it into an easily separable form.
[0010] Ion exchange method: For ionic catalysts, ion exchange resins can be used to exchange catalyst ions from the mixture, thereby achieving separation.
[0011] 3. Membrane separation method
[0012] Membrane filtration: Filtering a mixture using a membrane with a specific pore size, so that catalyst particles or large molecules are retained, while small molecules such as organic carbonates pass through the membrane pores to the other side.
[0013] Pervaporation: By utilizing the difference in vapor pressure of the components in a mixture, a pressure difference is formed on both sides of the membrane, allowing the component with higher vapor pressure to preferentially permeate through the membrane, thereby achieving separation.
[0014] The above method for separating carbonate catalysts has the following drawbacks: 1. It can only separate a limited amount at a time, resulting in low separation efficiency of carbonate catalysts; 2. It cannot detect whether the separated carbonate contains catalyst components, which makes it easy for carbonates that have not been completely separated from the catalyst to be discharged.
[0015] Therefore, it is necessary to design a carbonate catalyst separation device to solve the problems mentioned above. Utility Model Content

[0038] For examples, please refer to Figure 1-3 This utility model provides a technical solution:
[0039] A carbonate catalyst separation device includes a separation cylinder 1, end caps 2 fixedly connected to the left and right sides of the separation cylinder 1, and fixed brackets 3 fixedly connected to the outer sides of the end caps 2. A feed pipe 4 is fixedly installed on the rear side of the separation cylinder 1 on one side of the right end cap 2. A discharge pipe 9 is fixedly installed at the bottom of the separation cylinder 1 on one side of the left end cap 2. A separation chamber 5 is opened on the right side of the interior of the separation cylinder 1, and a conveying chamber 6 is opened on the left side of the interior of the separation cylinder 1. A separation structure 7 is installed inside the separation chamber 5, and a conveying structure 8 is installed inside the conveying chamber 6.
[0040] For details, please refer to Figure 1 , Figure 2 as well as Figure 3 The separation structure 7 includes multiple separation tubes 71 connected inside the separation chamber 5. A connecting tube 72 is fixedly connected to the side of the multiple separation tubes 71 away from the conveying chamber 6. The multiple separation tubes 71 are fixedly connected to one end of the feed pipe 4 through multiple connecting tubes 72. A filter membrane 73 is fixedly installed inside the multiple connecting tubes 72. The multiple connecting tubes 72 are connected by threads, and the filter membrane 73 is clamped in the internal cavity of the connecting tube 72. The lower side of one side of the conveying chamber 6 is connected to the inside of the discharge pipe 9, and the other side is connected to the multiple separation tubes 71.
[0041] In this embodiment, after the carbonate catalyst enters the separation chamber 5, multiple separation tubes 71 are set inside the separation chamber 5. When the catalyst and organic carbonate enter the separation tubes 71, the organic carbonate and catalyst are separated by the filter membrane 73 located in the connecting tube 72 and inside the separation tubes 71. The mixture is filtered by the membrane with a specific pore size, so that the catalyst particles or large molecules are retained, while the small molecules of organic carbonate are discharged through the membrane pores, thereby realizing the separation of carbonate catalyst.
[0042] For details, please refer to Figure 1 as well as Figure 2 The conveying structure 8 includes a conveying motor 81 fixedly installed on the top of one side of the left end cover 2. A first bevel gear 82 is fixedly connected to the bottom output end of the conveying motor 81. A second bevel gear 83 is meshed with one side of the first bevel gear 82. A shaft is fixedly connected inside the second bevel gear 83 by a key, and a conveying blade 84 located on its periphery is fixedly connected to the shaft.
[0043] In this embodiment, the first bevel gear 82 is driven to rotate by the conveyor motor 81, which in turn drives the second bevel gear 83 to rotate, thereby causing the conveyor blade 84 to rotate. The carbonate material is conveyed by the rotation of the auger-type conveyor blade 84.
[0044] For details, please refer to Figure 1 as well as Figure 3 A circulation pipe 10 is threadedly connected between the discharge pipe 9 and the feed pipe 4. One side of the circulation pipe 10 is fixedly connected to the discharge pipe 9 via a first electric three-way valve 11 (one inlet, two outlets), and the other side of the circulation pipe 10 is fixedly connected to the feed pipe 4 via a second electric three-way valve 111 (two inlets, one outlet). A load-bearing connecting pipe 12 is threadedly connected between the top of the discharge pipe 9 and the bottom of the separation cylinder 1. A material detector 13 is threadedly connected between the load-bearing connecting pipe 12 and the second electric three-way valve 111. The material detector 13 is an infrared spectrometer that analyzes substances by utilizing their absorption characteristics of infrared light. Different compounds have specific absorption peaks in their infrared spectra, which can be used to detect the presence of specific catalyst components in a sample.
[0045] In this embodiment, after the carbonate catalyst is separated, the contents of the carbonate are detected by a material detector 13. When the presence of catalyst components is detected again, the first electric three-way valve 11 and the second electric three-way valve 111 are opened and closed respectively to connect the lower end of the bearing connecting pipe 12 and the circulation pipe 10 and the lower end of the circulation pipe 10 and the feed pipe 4, so that the organic carbonate is fed back into the separation chamber 5 through the feed pipe 4 for further separation, thereby improving the separation quality.
[0046] Preferably, a maintenance cover 14 is rotatably connected to the top side of the separation chamber 5 via a hinge, and a connecting cover 15 is fixedly connected to the maintenance cover 14 away from the hinge via bolts. The other side of the connecting cover 15 is integrally fixedly connected to the outer wall of the separation cylinder 1. By opening the maintenance cover 14, the inside of the separation chamber 5 can be disassembled, cleaned, and disinfected.
[0047] The working process of this utility model is as follows: When using this carbonate catalyst separation device, after the carbonate catalyst material enters the separation chamber 5, multiple separation tubes 71 are set inside the separation chamber 5. When the catalyst and organic carbonate enter the separation tubes 71, the organic carbonate and catalyst are separated by the filter membrane 73 located in the connecting tube 72 and inside the separation tubes 71. The mixture is filtered by a membrane with a specific pore size, so that catalyst particles or large molecules are retained, while small organic carbonate molecules are discharged through the membrane pores, thereby achieving the separation of the carbonate catalyst. Afterwards, the carbonate material is sent into the conveying chamber 6, and the first bevel gear is driven by the conveying motor 81. Rotation of valve 82 synchronously drives the second bevel gear 83 to rotate, which in turn causes the conveying blade 84 to rotate. The rotation of the auger-type conveying blade 84 conveys the carbonate material. After the carbonate catalyst is separated, the internal material of the carbonate is detected by a material detector 13. When the presence of catalyst components is detected again, the first electric three-way valve 11 and the second electric three-way valve 111 are opened and closed respectively to connect the bearing connecting pipe 12 and the circulation pipe 10, and the lower end of the circulation pipe 10 and the feed pipe 4. This allows the organic carbonate to be fed back into the separation chamber 5 through the feed pipe 4 for further separation, thus improving the separation quality.
[0048] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
