Description

Technical Field

[0002] Plasticizers are currently widely used polymer additives in industrial production. Also known as plasticizers, any substance added to polymer materials that increases the plasticity of the polymer is called a plasticizer. The use of plasticizers can improve the performance of polymer materials, reduce production costs, and improve production efficiency. They are an important class of chemical product additives and are commonly used as additives in plastic products, concrete, mortar, cement, gypsum, cosmetics, and cleaning agents, especially in polyvinyl chloride plastic products.

When plasticizer raw materials are heated, they produce components with different boiling points.

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Please see Figure 1-3This utility model provides a technical solution: a distillation device for the production of environmentally friendly plasticizers, comprising:

[0022] Distillation column outer frame 1;

[0023] The cooling structure is provided in multiple ways, and the multiple cooling structures are fixedly arranged at equal intervals within the outer frame 1 of the distillation column.

[0024] Each cooling structure includes a collecting ring frame 2, an inner condensation frame 3, an outer condensation frame 4, and a water-cooling pipe 5. The outer wall of the outer condensation frame 4 is fixed with multiple fixing rods 6 at equal intervals along its circumferential surface. The ends of the multiple fixing rods 6 that are far apart from each other are fixed inside the outer frame 1 of the distillation column. The outer wall of the inner condensation frame 3 is fixedly embedded inside the outer condensation frame 4. The outer wall of the water-cooling pipe 5 is fixedly embedded between the inner condensation frame 3 and the outer condensation frame 4. One end of the outer wall of the water-cooling pipe 5 is fixedly embedded inside the outer frame 1 of the distillation column. The outer wall of the collecting ring frame 2 is fixedly embedded inside the outer frame 1 of the distillation column and is located below the inner condensation frame 3 and the outer condensation frame 4.

[0025] In this implementation scheme: the water-cooling pipe 5 can be clamped by the inner condensation frame 3 and the outer condensation frame 4, so that the water-cooling pipe 5 absorbs the temperature of the inner condensation frame 3 and the outer condensation frame 4. The temperature of the inner condensation frame 3 and the outer condensation frame 4 is controlled by the flow rate in the water-cooling pipe 5, so that the vapor flowing in the inner condensation frame 3 and the outer condensation frame 4 can be condensed to different degrees. The vaporized components can be gradually condensed in the distillation column during the ascent in the column, so that components with different boiling points condense at different heights in the column, thereby achieving separation and improving the condensation effect. The collecting ring frame 2 can collect the liquid that slides down the inner wall of the inner condensation frame 3. The outer condensation frame 4 is fixed in the outer frame 1 of the distillation column by multiple fixing rods 6.

[0026] Specifically, the outer wall of the collecting ring frame 2 is connected to the discharge frame 7, and the outer wall of the discharge frame 7 is fixedly embedded in the outer frame 1 of the distillation column.

[0027] In this embodiment, the liquid collected in the collection ring frame 2 can be discharged through the discharge frame 7.

[0028] Specifically, a sliding ring 8 is fixedly embedded at the bottom of the inner wall of the collecting ring frame 2, and an air baffle 9 is fixedly embedded in the inner wall of the collecting ring frame 2.

[0029] In this embodiment, the liquid in the collection ring 2 can be slid into the connection between the collection ring 2 and the discharge frame 7 by means of the sliding ring 8.

[0030] Specifically, a fixing plate 10 is fixedly installed on one side of the outer wall of the distillation column frame 1, and a water-cooling controller 11 is installed on the top of the outer wall of the fixing plate 10.

[0031] In this embodiment, the water-cooled controller 11 can be fixed to one side of the outer frame 1 of the distillation column by means of the fixing plate 10.

[0032] Specifically, one end of the water-cooling pipe 5 is connected to the water-cooling controller 11.

[0033] In this embodiment, the flow rate of cooling water in the water-cooling pipe 5 can be controlled by the water-cooling controller 11, thereby controlling the temperature of the inner condensation frame 3 and the outer condensation frame 4.

[0034] Specifically, an outlet pipe 12 is connected to the top of the outer wall of the distillation column frame 1.

[0035] In this embodiment, steam can be fully released through the vent pipe 12.

[0036] In use, the inner condensation frame 3 and the outer condensation frame 4 can clamp the water-cooling pipe 5, allowing the water-cooling pipe 5 to absorb the temperature of the inner condensation frame 3 and the outer condensation frame 4. The flow velocity within the water-cooling pipe 5 is used to control the temperature of the inner condensation frame 3 and the outer condensation frame 4, thereby causing the vapor flowing in the inner condensation frame 3 and the outer condensation frame 4 to condense to different degrees. This allows for the gradual condensation of vaporized components as they rise within the distillation column, enabling components with different boiling points to condense at different heights within the column, achieving separation and improving the condensation effect. The collecting ring frame 2 can collect the condensate. The liquid sliding down the inner wall of the inner condensation frame 3 is fixed to the outer frame 1 of the distillation column by multiple fixing rods 6. The discharge frame 7 allows the liquid collected in the collection ring frame 2 to flow out. The sliding ring 8 allows the liquid in the collection ring frame 2 to slide into the connection between the collection ring frame 2 and the discharge frame 7. The fixing plate 10 can fix the water cooling controller 11 to one side of the outer frame 1 of the distillation column. The water cooling controller 11 can control the flow rate of cooling water in the water cooling pipe 5, thereby controlling the temperature of the inner condensation frame 3 and the outer condensation frame 4. The steam outlet pipe 12 can allow sufficient steam to flow out.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
