[0002] Methanol is an important organic chemical raw material that can be used in chemical industry, energy, agriculture, medicine and scientific research. It has a wide range of uses. The synthesis of methanol requires a methanol production reaction system. In the existing methanol production reaction system, the staff usually adds the two pressurized raw materials into the reaction barrel, then adds the catalyst, and then heats the reaction barrel to control the temperature in the reaction barrel to be appropriate. After the reaction is completed, the methanol in the reaction barrel is collected; The existing methanol production reaction system has the following problems: when the reaction occurs, the two raw gases are not fully mixed, resulting in the raw gases not reacting completely and there will be residual raw gases, which will reduce the production efficiency of methanol. After the reaction is completed, methanol droplets will remain on the inner wall of the reaction barrel, wasting resources.
