Description

Technical Field

[0001] This utility model belongs to the field of water treatment technology, specifically relating to a pilot-scale device for ion exchange resin white spheres. Background Technology

[0002] Ion exchange resin white spheres (such as styrene-divinylbenzene copolymer white spheres) are key precursors in the preparation of ion exchange resins. Their properties (such as particle size distribution, porosity, and mechanical strength) directly affect the quality of the final resin product. As a highly efficient water treatment material, ion exchange resin white spheres are widely used in water softening, desalination, and wastewater treatment. To verify the performance and applicability of ion exchange resins, medium-scale verification experiments are usually conducted in the laboratory and pilot-scale stages.

[0003] Currently, traditional ion exchange resin experimental devices are mostly small-scale laboratory equipment, making it difficult to conduct large-scale pilot-scale tests and production verification. The lack of pilot-scale devices capable of simulating actual production conditions hinders the promotion and widespread application of ion exchange resins in practical applications. Therefore, developing a pilot-scale device for ion exchange resin white spheres that can simulate actual usage environments is of significant practical importance. Utility Model Content

Detailed Implementation

[0020] The present invention will be further described below with reference to the embodiments.

[0021] Example 1:

[0022] Please see Figure 1-4 This invention provides a pilot-scale device for ion exchange resin white spheres, comprising a reaction body 1, a storage body 2, and an annular baffle structure 4. The storage body 2 is fixedly connected to the bottom end of the reaction body 1, and an observation window 3 is provided on the front of the outer surface of the storage body 2. The annular baffle structure 4 is fixedly connected to the outer periphery of the bottom end of the storage body 2. A bottom chamber 5 is opened inside the annular baffle structure 4, and four support columns 6 are fixedly connected to the top of the inner surface of the bottom chamber 5, which are symmetrically arranged in pairs. A circulation pump 7 is fixedly connected to the left side of the inner surface of the annular baffle structure 4, and an inlet pipe 8 is fixedly connected to the top of the circulation pump 7. An outlet pipe 9 is fixedly connected to the right side of the outer surface of the circulation pump 7. A slag discharge structure 10 is provided on the right side of the top of the inner surface of the bottom chamber 5. Through the cooperation of the circulation pump 7 with the inlet pipe 8 and the outlet pipe 9, forced circulation heat exchange of the reaction liquid can be realized, improving temperature control accuracy and avoiding side reactions caused by temperature fluctuations. The circulation pump 7 can re-transport the separated aqueous phase to the reaction system, reducing solvent waste and improving resource utilization.

[0023] Further as Figure 3 and Figure 4 As shown, it is worth noting that the reaction body 1 has a reaction cavity 101 inside. A partition plate 102 is fixedly connected to the bottom of the reaction cavity 101. The upper surface of the partition plate 102 has a number of leakage holes 103 arranged in a ring. Through the structural design of the partition plate 102 and the leakage holes 103, the reaction liquid forms a dynamic flow between the reaction cavity 101 and the stirring cavity 201, reducing local overheating.

[0024] Further as Figure 1 , Figure 3 and Figure 4As shown, it is worth noting that a support plate 11 is fixedly connected to the inner side of the top of the reaction body 1, a water inlet pipe 12 is fixedly connected to the upper left corner of the top of the support plate 11, a feed pipe 13 is fixedly connected to the lower right corner of the top of the support plate 11, and a rotating motor 14 is fixedly connected to the center of the top of the support plate 11.

[0025] Further as Figure 3 and Figure 4 As shown, it is worth noting that the output end of the rotating motor 14 is fixedly connected to a rotating rod 15, and several stirring rods 16 arranged in a ring array are fixedly connected to the upper and lower ends of the outer surface of the rotating rod 15. This application adopts a combination design of frequency conversion stirring and multi-stage stirring rods 16 to ensure that the monomer and the dispersed phase in the reaction system are fully mixed and to avoid local uneven concentration.

[0026] Further as Figure 3 and Figure 4 As shown, it is worth noting that the storage body 2 has a stirring cavity 201 inside, and the stirring rod 16 passes through the center of the partition plate 102 and is rotatably connected to the bottom of the stirring cavity 201.

[0027] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth noting that the stirring rod 16 has a flow cavity 17 inside, and the bottom of the outer surface of the top stirring rod 16 has several liquid outlet holes 18 arranged in a rectangular array. The rotating rod 15 has a circulation cavity 19 inside. The circulation cavity 19 is interconnected with the flow cavity 17 and the liquid outlet pipe 9. Through the design of the flow cavity 17 and the liquid outlet holes 18, the reaction liquid can achieve internal circulation during the stirring process, further enhancing the mixing effect and making the white ball particle size distribution more uniform.

[0028] Further as Figure 2 and Figure 4 As shown, it is worth noting that the slag discharge structure 10 includes a slag discharge pipe 1001. A valve 1002 is provided on the outer surface of the slag discharge pipe 1001. An adjusting rod 1003 is rotatably connected to the outer surface of the valve 1002. A switch knob 1004 is fixedly connected to the top outer side of the adjusting rod 1003.

[0029] This scheme has the following working process: First, a mixture of monomers such as styrene and divinylbenzene is added to the reaction cavity 101 through the feed pipe 13. An aqueous phase containing dispersants and stabilizers is injected through the water inlet pipe 12 to form an oil / water dispersion system. At this time, the rotating motor 14 is started to drive the rotating rod 15 to rotate, causing the stirring rod 16 to shear and stir the reaction liquid, promoting the uniform dispersion of monomer droplets. During the reaction, the exothermic polymerization is forcibly circulated and heat exchanged through the circulating pump 7: the reaction liquid flows into the stirring cavity 201 through the drain hole 103, then enters the circulating pump 7 through the liquid inlet pipe 8. The heat-exchanged liquid returns to the reaction system through the liquid outlet pipe 9, maintaining a stable reaction. Under stirring and temperature control conditions, the monomers gradually polymerize to form white spherical particles with uniform particle size distribution. After the reaction is terminated, stirring is stopped, and the white spherical particles settle under gravity. The settled white spherical products accumulate at the bottom of the storage body 2. The valve 1002 of the slag discharge structure 10 is opened, and the residual polymerization slag or unreacted monomers are discharged through the slag discharge pipe 1001. The regulating rod 1003 and the switch knob 1004 can control the slag discharge speed to avoid blockage. After the reaction is completed, the cleaning solvent can be injected through the water inlet pipe 12 to carry out online cleaning in conjunction with the stirring system. The observation window 3 facilitates the inspection of the cleanliness of the equipment's interior, reducing the time required for manual disassembly and maintenance.

[0030] Based on the above working process, it can be seen that: This utility model adopts a combination design of frequency conversion stirring and multi-stage stirring rod to ensure that the monomer and dispersed phase in the reaction system are fully mixed, avoiding local uneven concentration. Through the design of the flow cavity and liquid outlet, the reaction liquid achieves internal circulation during the stirring process, further enhancing the mixing effect and making the white ball particle size distribution more uniform. Through the structural design of the partition plate and the leakage hole, the reaction liquid forms a dynamic flow between the reaction cavity and the stirring cavity, reducing local overheating. Through the cooperation of the circulation pump and the liquid inlet and liquid outlet pipes, forced circulation heat exchange of the reaction liquid can be achieved, improving temperature control accuracy and avoiding side reactions caused by temperature fluctuations. The circulation pump can re-transport the separated aqueous phase to the reaction system, reducing solvent waste and improving resource utilization.
