Novel gas-liquid-solid three-phase reactor for synthesizing tetramethoxysilane

The novel gas-liquid-solid three-phase reactor comprises a reaction mechanism, a sample injection mechanism and a stirring device, the reaction mechanism comprises a reaction area, a sample introduction area arranged at the bottom of the reaction area and a calabash blowout prevention area arranged at the top of the reaction area, according to the utility model, through the arrangement of the baffles in the calabash-shaped blowout prevention area, solid and liquid are blocked by the baffles in the calabash-shaped blowout prevention area instead of reaching the discharge port if a material spraying condition occurs, and a solvent, silicon powder and a catalyst return to the reaction area again for continuous reaction; due to material spraying, the air pressure in the whole device can be recovered to be normal again, methanol is pumped into the sample injection area through the peristaltic pump for reaction and use, and the materials in the reaction area are fully mixed in a stirring manner, so that the reactio
