[0003] A search revealed that the announcement number is CN216404309U, entitled "An Oil Removal Reactor for Coal-based Fischer-Tropsch Wax," which includes a reactor body. Research and analysis revealed that although it has the advantage of high oil extraction efficiency, it also has the following disadvantages to a certain extent.

[0004] For example, during the use of this device, the processing conditions are usually affected by external factors, and the processing conditions cannot be adjusted according to the processing requirements. It is inconvenient to process the raw materials inside and inconvenient for people to use. In order to solve the above technical problems, we have designed a reaction vessel for the production of coal-based Fischer-Tropsch mixed alcohols. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model adds the raw materials to be processed into the mixing tank through the feeding pipe. The driving shaft of the motor drives the stirring rod to rotate, and the stirring rod mixes the raw materials. The air pressure in the mixing tank and the top cover is detected by the air pressure gauge. When the air pressure is low, the air pump is used to inject air into the mixing tank and the top cover to increase the air pressure. If the air pressure in the mixing tank and the top cover is high, the third solenoid valve is opened to release air and reduce the air pressure.

[0015] 2. This utility model heats the water in the heating tank using a heater. A first solenoid valve connects the pump's outlet pipe to the heating shell, allowing the pump to draw hot water from the heating tank and inject it into the heating shell. The hot water in the heating shell heats the raw materials in the mixing tank, facilitating the mixing reaction. The heated hot water flows back to the heating tank through a pipe. After addition is complete, the processed raw materials are discharged through a discharge pipe. Then, the first solenoid valve is closed, and a second solenoid valve connects the pump's outlet pipe to a spray nozzle. The pump draws hot water from the heating tank and injects it into the spray nozzle through the pipe and the second solenoid valve, cleaning the inner wall of the mixing tank with water.
