[0002] A chemical reactor is a device used to achieve chemical reactions, usually a closed container with a stirring device. It is widely used in chemical processes such as synthesis, decomposition, and conversion in the chemical industry. The reactor can provide a suitable temperature, pressure, and mixing environment so that the reactants can react chemically under specific conditions to produce the target product. The design and use of chemical reactors must comply with relevant safety regulations and process requirements to ensure the efficient conduct of chemical reactions and the safety of personnel and equipment. In actual production, the size, design, and function of the reactor will be determined according to the specific chemical reaction and production scale.

[0003] Before the chemical material solution is reacted and processed, the solution needs to be transported to the reactor, and after the reaction is completed, the solution needs to be safely taken out.

Waste gas is harmful to a certain extent. Direct discharge will affect the natural environment, pollute the environment, and affect the physical and mental health of the people. When adding and discharging chemical solutions to the reactor, the waste liquid is corrosive to a certain extent. If the waste liquid leaks, it will cause damage to the staff and the surrounding environment. Utility Model Content
