Description

Technical Field

[0001] The utility model specifically relates to a gas-liquid reactor for recycling and reusing a chemical catalyst. Background Art

[0002] In the production process of petroleum, chemical industry, etc., gas-liquid reactor is a common equipment. When two liquid raw materials need to be injected into the gas-liquid reactor for gas-liquid reaction, due to the lack of premixing and stirring function of the two liquid raw materials, the two liquid raw materials are mixed unevenly, resulting in insufficient gas-liquid reaction with the gas. In addition, the gas-liquid reaction is usually stirred by a stirring rotor during mixing, and the rotation of the stirring rotor needs to be driven by a motor. For safety reasons, the motor is usually placed outside the reaction container. The connection between the motor and the stirring rotor is easily corroded by chemical raw materials. Once the stirring rotor is damaged, it will not only affect the production efficiency, but also cause great safety hazards.

[0003] Moreover, during the gas-liquid reaction process, chemical catalysts need to be added, but the dosage of the catalyst cannot be controlled, the catalytic effect of the gas-liquid reaction is not good, and generally chemical catalysts exist in the form of solid particles in order to fully contact with the reactants. Usually, the catalyst is directly added to the reactor, but the recycling of the catalyst has become a difficult problem to solve. Utility Model Content
