[0002] When the aluminum trichloride production process adopts the current domestic traditional aluminum trichloride production process, chlorine gas is introduced into molten aluminum water for reaction to produce aluminum trichloride gas, and the aluminum trichloride gas crystallizes and precipitates in a trap. The reaction between chlorine gas and aluminum water is carried out in a reaction furnace. The temperature of the aluminum water in the reaction furnace is relatively high, up to more than 900 degrees Celsius at the highest. The on-site temperature is relatively high, and there are relatively high safety risks during the inspection process and the operation process.
