Description

Technical Field

[0001] The utility model belongs to the technical field of ion exchange resin processing equipment, in particular to a laboratory macroporous adsorption resin porogen recovery system. Background Art

[0002] Macroporous adsorption resin is a type of ion exchange resin. Its interior is a porous sponge structure, and the resin is mostly spherical particles. Macroporous means that the interior of the ion exchange resin has more macroporous structures, and its surface area is large, which can more effectively adsorb ions and organic matter in aqueous solutions. Macroporous resin has the advantages of being reusable, environmentally friendly, highly efficient, and easy to store. It can save energy consumption, storage and transportation costs, and is a material with a high comprehensive index. Therefore, macroporous resin has been widely used in the environmental protection, food, and pharmaceutical industries.

[0003] The hot topic of controversy about macroporous resin adsorption technology is the toxicity of porogens and degradation products. Because the resin has a reticular structure and large pores, organic solvents need to be added during preparation. These organic solvents are mostly toxic liquids that are retained in the pores of the resin, commonly known as porogens, which makes many people worry. In the prior art, there is no simple and effective recovery method. If the porogen cannot be fully recovered and effectively treated, it will not only affect the safety of the macroporous adsorption resin, but also cause waste of resources, increase production costs, and increase environmental protection disposal.

DETAILED DESCRIPTION

[0018] The utility model discloses a laboratory system for recovering macroporous adsorption resin porogens, such as Figure 1 As shown, it includes a filter tank, the top of which is connected to an organic solvent heating device 01 through a pipeline, and the bottom is connected to a liquid heating device 09 through a pipeline. A high-boiling-point porogen recovery device 11 is connected to the pipeline between the filter tank and the liquid heating device 09, and a low-boiling-point porogen recovery device 06 is connected to the filter tank near the top through a pipeline. The heating medium inside the liquid heating device 09 is water. The steam generated by heating the liquid medium by the liquid heating device 09 takes away the low-boiling-point porogen in the filter tank and enters the low-boiling-point porogen recovery device 06, the organic solvent is heated by the organic solvent heating device 01 to form a gaseous organic solvent, the condensation reflux pipe 03 cools the gaseous organic solvent to form a liquid solvent with a certain concentration, takes away the high-boiling-point porogen in the resin in the filter tank and enters the high-boiling-point porogen recovery device 11, and then the organic solvent is condensed by the steam and sent to the low-boiling-point recovery device.

[0019] As a specific embodiment, as shown in the figure, the filter tank includes a tank body, and the inside of the tank body is provided with a condensation reflux pipe 03, a first tetrafluoro filter plate 12 and a second tetrafluoro filter plate 13 in sequence from top to bottom, and the first tetrafluoro filter plate 12 and the second tetrafluoro filter plate 13 are uniformly filled with resin. The first tetrafluoro filter plate 12 and the second tetrafluoro filter plate 13 are uniformly configured with filter holes. The side wall of the tank body is provided with a resin feed port 05 and a resin discharge port 07, the resin feed port 05 is provided below the first tetrafluoro filter plate 12, and the resin discharge port 07 is provided above the second tetrafluoro filter plate 13, and the resin feed port 05 and the first tetrafluoro plate are connected to the low-boiling-point porogen recovery device 06 through a pipeline.

[0020] The working principle of the utility model is as follows:

[0021] The resin is filled between the first tetrafluoro filter plate 12 and the second tetrafluoro filter plate 13. When the heated organic solvent flows in from the top of the tank body, it will first pass through the condensation reflux pipe 03, and condense to form a liquid solvent with a certain concentration after cooling. Because the first tetrafluoro filter plate 12 is evenly provided with filter holes, the organic solvent can evenly enter the resin below after passing through the first tetrafluoro filter plate 12. The high-boiling-point porogen will enter the high-boiling-point porogen recovery device 11 through the pipeline, and the remaining organic solvent will continue to flow downward, passing through the resin filled in the tank body. The remaining low-boiling-point organic solvent flows out from the bottom of the tank body, and under the action of the water vapor generated by the liquid heating device 09, the porogen is recovered to the low-boiling-point porogen recovery device 06. In this process, the resin between the two tetrafluoro filter plates forms a macroporous adsorption resin, and the high-boiling-point porogen and low-boiling-point quality control agent in the organic solvent can be fully and effectively recovered.

[0022] As a specific embodiment, as shown in the figure, a first valve 02 is provided on the pipeline between the top of the tank body and the organic solvent heating device 01, a second valve 04 is provided on the pipeline between the side wall and the low-boiling-point porogen recovery device 06, a third valve 08 is provided on the pipeline between the bottom and the liquid heating device 09, and a fourth valve 10 is provided on the pipeline between the bottom and the high-boiling-point porogen recovery device 11. Each valve is a one-way valve, and the backflow of the porogen and the organic solvent is prevented by setting multiple valves.

[0023] In summary, the utility model provides a porogen recovery device with a simple and practical structure, which can fully and effectively recover high-low point and low boiling point porogens, ensure the safety of macroporous adsorption resin, improve resource utilization, and reduce production costs and environmental protection disposal costs.
