Treatment technology of organic silicon slag slurry

Abstract

The invention belongs to the technical field of organic silicon production and particularly relates to a treatment technology of organic silicon slag slurry. A distillation kettle is used in the treatment technology and comprises an upper sealing head, a cylindrical barrel, a conical barrel, a residue outlet and a stirring module. The stirring module comprises an air cylinder, supporting plates, connecting rods and arc-shaped sliding blocks. The set of supporting plates is arranged in the middle of a push rod of the air cylinder in a spaced mode, and the set of connecting rods is arranged at the outer circle of each supporting plate in the radial direction of the supporting plate; one end of each connecting rod is fixedly connected with one side of the corresponding arc-shaped sliding block; and elastic films are arranged in through grooves, one side of each elastic film is fixedly connected with one side of the corresponding through groove, the other ends of the elastic films are fixedly connected with sliding plates, penetrating notches are formed in the middles of the elastic films, and the sliding plates slide for controlling the notches to be closed or opened. According to thetreatment technology of the organic silicon slag slurry, the push rod drives the supporting plates to move up and down, when sliding to the cylindrical barrel along with the arc-shaped sliding blocks, the sliding plates move outwards, the notches are opened, thus the flowing path of the organic silicon slag slurry is increased, convection of the organic silicon slag slurry is more sufficient, andthe distill-off efficiency of a high-boiling product is improved.

Description

technical field [0001] The invention belongs to the technical field of organosilicon production, in particular to a process for treating organosilicon slurry. Background technique [0002] Organosilicon slurry is the waste produced during the synthesis of organosilicon monomers, especially methyl chlorosilane monomers. It is mainly composed of a large amount of high boilers and a small amount of unreacted silicon powder and copper powder brought out of the fluidized bed. , High boiler refers to the high boiling point polysilane mixture with silicon-silicon bond, silicon-carbon-silicon bond, silicon-oxygen-silicon bond, silicon-oxygen-silicon bond, silicon-silicon bond, silicon-carbon-silicon bond, silicon-oxygen-silicon bond, and a boiling range of 70.3-250 °C produced during the synthesis of methylchlorosilane monomer. . If this part of the material is exposed to the air, it will burn or form a strong acid mist or liquid. Therefore, if it is directly discharged, it will ca...

Problems solved by technology

[0005] This technical scheme can steam out the high boilers, but this scheme uses the rotary stirring method to stir the organic silicon slurry, so that the temperature of the organic silicon slurry near the inner wall of the barrel is relatively high, and the convection of the organic silicon slurry is not sufficient, which restricts high The evaporation efficiency of boiling matter makes the treatment efficiency of silicone slurry lower
