Description

Technical Field

[0001] The utility model relates to the technical field of reaction devices, in particular to a reaction device for gas-liquid reaction of electronic materials. Background Art

[0002] Gas-liquid reaction is a commonly used reaction mode in the synthesis of electronic materials. The gas-liquid reaction process refers to a reaction in which the components in the gas phase must enter the liquid phase. The liquid phase can be a liquid reactant or a catalyst solution.

[0003] At present, the gas is generally directly introduced into the reactor below the liquid level for gas-liquid reaction, but the gas-liquid contact surface is small in this method and the reaction efficiency is low. There are also improvements to the reactor, in which the gas is dispersed in the liquid phase through a dispersion device to promote the gas-liquid reaction, but the dispersion of the gas alone can only improve the gas-liquid mixing degree to a certain extent. If the gas-liquid reaction efficiency is to be further improved, the reaction device needs to be improved. Utility Model Content

[0004] The purpose of the utility model is to provide a reaction device for gas-liquid reaction of electronic materials, which integrates liquid dispersion spraying and gas dispersion, fully increases the gas-liquid contact area, effectively improves the gas-liquid reaction efficiency, shortens the reaction time, and reduces the energy consumption of the production process.

[0005] The reaction device for gas-liquid reaction of electronic materials described in the utility model comprises a reaction kettle body, a spray head arranged at the top of the reaction kettle body, and a gas disperser arranged at the bottom of the reaction kettle body; the spray head is connected to the circulating material outlet at the bottom of the reaction kettle body through a material circulation pipe, and the gas disperser is connected to the gas delivery pipe.

[0006] Preferably, the reactor body is provided with a jacket, and the material in the reactor body is heated by passing a medium such as steam or heat-conducting oil into the jacket, or the material in the reactor body is cooled by adding cooling water.

[0007] Preferably, the reactor body is equipped with a stirring device to stir the materials in the reactor body to make them evenly mixed.

[0008] Preferably, the spray head is a shower-type spray head structure.

[0009] Further preferably, the spray heads are provided in two groups.

[0010] Preferably, the gas disperser is a circular ring structure, with gas outlets distributed above the ring and a pore size of 5 to 20 μm.

[0011] Preferably, the gas disperser is fixed inside the reactor body via a support frame.

[0012] In the reaction device of the utility model, the reaction kettle body, the jacket and the stirring device are the reaction units, which are mainly used to complete the heating and stirring reaction process; the gas disperser and the gas delivery pipe are the gas dispersion unit, which are mainly used to disperse the gas into tiny bubbles and promote the uniform dispersion of the gas in the liquid; the circulation pump and the spray head are the reaction liquid spray unit, which transport the reaction materials from the bottom of the reaction kettle body to the top of the reaction kettle body, and disperse the reaction liquid into tiny liquid droplets through high-speed spraying, thereby increasing the liquid-gas contact area.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The reaction device for gas-liquid reaction of electronic materials of the utility model integrates liquid dispersion spraying and gas dispersion in one, which can fully increase the gas-liquid contact area, effectively improve the gas-liquid reaction efficiency, shorten the reaction time, and reduce the energy consumption of the production process.
