Description

Technical Field

[0001] This utility model relates to the field of reaction device technology, specifically to a reaction device for improving the yield of polyoxyethylene ether. Background Technology

[0002] Reactors are widely used in the food, pharmaceutical, and chemical industries. People are quite familiar with their structure, which includes a jacketed vessel, a stirring device, and a drive unit that drives the stirring device.

[0003] Chinese patent CN201220699780.X discloses a reaction apparatus for improving the yield of polyoxyethylene ether, comprising a vessel body with a discharge port at the bottom, a vessel cover with a feed port connected to the vessel body via a flange, and a stirring device. The key technical points are: 4-8 baffles perpendicular to the inner wall of the vessel body are uniformly arranged on the inner wall; 2-4 heat exchange ring tubes coaxial with the vessel body and limited by the baffles are arranged inside the vessel body; the stirring device consists of a stirring shaft and a V-shaped first stirring blade and a rectangular second stirring blade limited by the stirring shaft, wherein the first stirring blade is limited at the bottom of the vessel body, and the second stirring blade is limited between two adjacent heat exchange ring tubes. The parallel arrangement of heat exchange ring tubes made of thermally conductive polymer material inside the reaction vessel greatly improves the heat exchange efficiency; the baffles arranged around the inner wall of the vessel body create vortices between the baffles, increasing the flow velocity of the reactants, thus improving both reaction efficiency and heat exchange efficiency.

[0004] The reaction apparatus for improving the yield of polyoxyethylene ether described in the aforementioned patent stirs the polyoxyethylene ether to fully integrate the reaction liquid with the catalyst. Although the above method can improve the reaction efficiency of polyoxyethylene ether, the reaction between polyoxyethylene ether and catalyst is a strongly exothermic process, which generates a large amount of heat. The device only uses symmetrical heat exchange tubes to remove the heat from the device, resulting in uneven heat distribution. Local overheating can easily deactivate the catalyst, leading to poor reaction performance for high polyoxyethylene ether yield. Utility Model Content

The uniform spraying ensures that the catalyst can fully contact the polyoxyethylene ether. A motor 1 is installed at the top center of the cover 3. The power output end of the motor 1 is connected to a rotating shaft 19. Scrapers 17 are symmetrically installed on both sides of the top of the rotating shaft 19. A stirring blade 14 is fixed on the rotating shaft 19 at the lower end of the scraper 17. Stirring blades 18 are symmetrically arranged on both sides of the stirring blade 14. A condensation circulation pipe 13 is evenly distributed on the inner wall of the heat dissipation box 4. Two circulating fans 15 are symmetrically fixed at the bottom of the heat dissipation box 4. The design of the condensation circulation pipe 13 can realize the heat exchange in the device and realize the heat exchange of the coolant. In addition, the design of the circulating fans 15 can ensure the uniform distribution of heat around the reaction box 16, avoid the local overheating of the reaction box 16, and effectively maintain the yield of polyoxyethylene ether in the device.

[0024] like Figures 1-2 As shown, in this embodiment, a material pipe 2 is installed on one side of the top of the catalyst storage box 10, and a feed pipe 6 is provided on the side wall of the cover 3 opposite to the material pipe 2. A discharge pipe 9 is provided at the lower end of one side wall of the heat dissipation box 4.

[0025] like Figures 1-2 As shown, in this embodiment, the feed pipe 2 is inserted into the cover 3 and the catalyst storage tank 10, the feed pipe 6 is inserted into the cover 3, and the discharge pipe 9 is connected to the flange of the reaction tank 16. The design of the feed pipe 2 facilitates the addition of catalyst to the catalyst storage tank 10, and the design of the feed pipe 6 facilitates the addition of various materials to the reaction tank 16 during the reaction process in the device.

[0026] like Figures 1-2 As shown, in this embodiment, the heat sink 4 is screwed to the workbench 5, the extension plate 2 8 is screwed to the reaction chamber 16, and the reaction chamber 16 is connected to the heat sink 4 by a slot.

[0030] The specific implementation process of this embodiment is as follows: When using the device, the workbench 5 needs to be fixed in an appropriate position, and an external power supply needs to be connected to the device. After adding an appropriate amount of polyoxyethylene ether into the reaction chamber 16, the heat dissipation chamber 4 is sealed with a lid. At the same time, the motor 1 drives the scraper 17, stirring blade 14, and stirring blade 18 on the rotating shaft 19 to rotate, thereby achieving stirring of the polyoxyethylene ether. Meanwhile, the catalyst in the catalyst storage tank 10 is transported to the atomizing nozzle 12 through the main pipe 11, thereby achieving pressurized spraying of the catalyst by the atomizing nozzle 12. During the stirring process of the polyoxyethylene ether, the two are fully fused. In the reaction, when polyoxyethylene ether reacts with the catalyst, heat is directly transferred to the circulation channel between the heat dissipation box 4 and the reaction box 16, enabling rapid heat removal from the heat dissipation box 4. Simultaneously, the design of the condenser circulation pipe 13 facilitates heat exchange within the device, enabling the coolant to exchange heat. Furthermore, the design of the circulation fan 15 ensures uniform heat distribution around the reaction box 16, preventing localized overheating and effectively maintaining the yield of polyoxyethylene ether within the device.
