Description

[0002] Acetonitrile is an important organic chemical raw material. In the production process of acetonitrile, heat exchanger is used. Heat exchanger can realize heat transfer, heat or cool the material in the reaction process, and ensure the reaction under suitable temperature conditions to improve production efficiency and product quality. Specifically, in the acetonitrile synthesis reaction, heat exchanger can take away the heat generated by the reaction in time to prevent the reaction temperature from being too high to cause side reactions; in the acetonitrile refining process, heat exchanger can heat or cool acetonitrile solution to promote separation and purification.

The upper fixing ring 4 and the lower fixing rings 3 cooperate with each other to fix the heat exchanger body 5, ensuring the stability of the heat exchanger body 5 during use. The heat exchanger body 5 is installed between the lower fixing rings 3 and the upper fixing rings 4. The support plate 2 and... A shock-absorbing assembly 6 is installed between the lower fixing rings 3. The shock-absorbing assembly 6 is used to buffer the vertical displacement of the heat exchanger body 5 caused by vibration.
