Description

Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to a reactor for dehydration, dehydrogenation and crystallization. Background Art

[0002] Reactors are widely used in the fields of petroleum, chemical industry, rubber, pesticide, dye, medicine and food. They are pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonization, polymerization and condensation. When preparing 1,1-bis(4-hydroxyphenyl)-3-phenylindane, a dehydration and dehydrogenation crystallization reactor is required for cooling and crystallization.

[0003] For example, a dehydration and dehydrogenation reaction kettle adapted for crystallization with the authorization announcement number "CN220257207U" can be installed by slidingly connecting the clamping rod and the clamping groove and setting the mounting through hole. When the inside of the crystallization kettle body needs to be cleaned, the mounting clamping rod can be inserted into the clamping groove, and then the transmission mechanism is started. The centrifugal force generated during rotation is used to extend the cleaning wire brush, so as to brush and clean the inner wall of the crystallization kettle body, thereby increasing the cleaning effect. It is easy to use and there is no need to remove the crystallization kettle cover. However, the reaction kettle adapted for dehydration and dehydrogenation and crystallization cannot splash water that flies up during rotation onto the inner wall of the crystallization kettle body, and thus more water needs to be injected to clean the inner wall of the crystallization kettle body, thereby increasing the working cost. Meanwhile, the reaction kettle adapted for dehydration and dehydrogenation and crystallization uses a wire brush to clean the inner wall of the crystallization kettle body. However, since there are many gaps between the steel wires on the wire brush and the position of the wire brush is fixed, the places where the wire brush has gaps inside the crystallization kettle body cannot be cleaned, and the operator needs to manually use special tools for secondary cleaning, thereby increasing the manual labor. Utility Model Content
