Description

Technical Field

[0001] The utility model relates to the technical field of chemical production, and more specifically, to a chemical reaction kettle for producing chemical products. Background Art

[0002] The reactor in chemical production is a container used for chemical reactions, in which various types of reactions can be carried out, such as dissolution, mixing, chemical synthesis, etc. It carries the core tasks of the production process. The material selection of the reactor is crucial and factors such as the properties of the reactants, temperature, and pressure must be taken into consideration.

[0003] When an existing reactor is performing an ester exchange reaction, in order to speed up its reaction rate, a certain amount of liquid catalyst needs to be added into the reactor. However, the existing reactor does not have a catalyst storage and injection device, which makes the catalyst addition operation not convenient and quick enough. In the existing reactor without legs, it is installed and placed by a support frame. However, since the support frame is generally a square frame structure, the reactor cannot be rotated and fine-tuned after installation. There may be bending at the connection between the reactor and the pipeline, which affects the stability of the connection. There are certain limitations in its use. The chemical reaction of the raw materials inside the reactor will produce a lot of waste gas, and once these waste gases are directly discharged, they will pollute the environment.
