Description

Technical Field

[0001] This utility model relates to the field of circulating water and alcohol tanks for plasticizer production, and more specifically, to a circulating water and alcohol tank for plasticizer production. Background Technology

[0002] In the engineering plastics industry, polymer additives, such as plasticizers, are used. Adding plasticizers during plastic production and processing can enhance the flexibility of polymer materials and stabilize their quality.

[0003] In the production of plasticizers, water-alcohol tanks are used to separate the alcohol and water produced during the production process. However, most existing water-alcohol tanks for plasticizer production are not convenient for classifying and collecting the alcohol and water produced during plasticizer production and for recycling the alcohol and water, thereby reducing the efficiency of raw material recycling in plasticizer production.

[0004] In the prior art, such as the authorized announcement number CN218795775U, this utility model relates to the field of plasticizer production and processing technology, and discloses a circulating water-alcohol tank for plasticizer production, including a reaction tank body, an alcohol-water separation tank and a collection tank. The top of the reaction tank body, the alcohol-water separation tank and the collection tank are movably fitted with a sealing cover. A feed pipe is fixedly connected to the upper end face of the sealing cover. A support frame is fixedly connected to the lower side of the outer surface of the reaction tank body. A heater is fixedly connected to the bottom surface of the reaction tank body. An upper suction pump is fixedly connected to the upper end face of the sealing cover. An upper conduit is fixedly connected to the output end of the upper suction pump. A condenser is fixedly connected to the outer surface of the upper conduit. A reflux pump is fixedly connected to the lower side of the outer surface of the alcohol-water separation tank. A reflux pipe is fixedly connected to the output end of the reflux pump. This circulating water-alcohol tank for plasticizer production allows the plasticizer production raw materials and catalyst to be put into the reaction tank body, and the alcohol-water separation tank can separate the alcohol and water after the reaction, and enable the unreacted raw materials to be recycled.

[0005] In the aforementioned patent, a horizontally distributed condenser is used for condensation. After the hot gas is introduced, it flows quickly and the condensation efficiency is low. Furthermore, the water-saturated alcohol and unsaturated alcohol are separated by a floating spring and a flow guiding mechanism, resulting in incomplete separation. The water-saturated alcohol and unsaturated alcohol are not clearly separated, and the unsaturated alcohol is easily discharged and collected during separation. Utility Model Content

It adopts a vertical condensation mechanism, in which hot gas is introduced and flows upward. It is cooled by water flow to improve cooling efficiency. The bottom is equipped with two opposing alcohol-water separation buckets, with a glass separation observation tube at the middle. By observing the separation observation tube, the layering situation can be judged, and the upper water-saturated alcohol can be exported, achieving precise separation.

[0007] To solve the above problems, the present invention adopts the following technical solution.

Solenoid valves can be used with different circuits to achieve the expected control, and the accuracy and flexibility of the control can be guaranteed. There are many types of solenoid valves, and different solenoid valves play different roles in the control system. The most commonly used are check valves, safety valves, directional control valves, speed regulating valves, etc. Solenoid valves are existing technology products, and their principles and control mechanisms are existing technologies.)

[0028] The reaction vessel body 1 is a jacketed tank, and an electric heating wire 100 is installed on the inner surface of the jacket layer on the outer side of the reaction vessel body 1. The electric heating wire is a component that generates heat through the thermal effect of electric current, mainly used to convert electrical energy into heat energy. It is widely used in various electric heating equipment. The core component and working principle of the electric heating wire are typically made of alloy materials such as iron-chromium-aluminum or nickel-chromium. When energized, it generates heat through resistance heating. Its heating efficiency is directly proportional to the current intensity, resistance value, and energizing time; this facilitates heating the water and alcohol inside the reaction vessel body 1.
