Falling film evaporator for preparing methyltris (methylethylketoximino) silane

The falling-film evaporator for preparing methyltris (methylethylketoximino) silane belongs to the technical field of falling-film evaporators, and is provided with the electric telescopic rod and the liquid outlet pipes corresponding to the plurality of shunt pipes, so that the liquid outlet pipes can be conveniently driven to descend to be butted with the shunt pipes for liquid injection during liquid injection, the uniformity of liquid injection is ensured, and the production efficiency is improved. Meanwhile, through arrangement of a first circulating pipe, a second circulating pipe and a heater, steam of a heating medium entering the shell is conveniently conveyed to the lower end, through arrangement of a heat preservation pipe, heat preservation is conveniently conducted in the shell, the evaporation effect is improved, through arrangement of a filter pipe, methyltris (methylethylketoxime) silane has certain toxins, and the heat preservation effect is improved. And gas generated after evaporation enter
