1. from organosilicon slag slurry, reclaim a method for effective high boiling material, it is characterized in that, comprise the steps:

  • (1) temperature passed in still kettle chuck from organosilane monomer synthesis is 200-300 DEG C of high temperature heat conductive oil, after heat exchange, cools the temperature to 180-280 DEG C, comes back in organosilane monomer synthesizer and use;

    (2) the high temperature sludge slurry in organosilane monomer synthesis of detergent tower reboiler is directly entered still kettle, in organosilane monomer synthesizer, thermal oil enters in still kettle chuck, 80-200 DEG C is heated to slag slurry in cylindrical shell by the heat exchange of thermal oil in chuck, open still kettle to stir simultaneously, control to enter in still slag slurry amount to 1/3 ~ 2/3 of cylindrical shell volume by tuning-fork type two position warning howler in still;

    (3) the high boiling material steam through a part of high boiling material evaporation of heat-conducting oil heating is back in backflow packing tower after condensation in overhead condenser;

    (4) after there is liquid level in the filler distribution device in backflow packing tower, open extraction variable valve, be recycled to high boiling material storage tank, the high boiling material reclaimed in high boiling material storage tank is sent to height and boils cracker;

    (5) hot-engine sludge after distillation is discharged in cooling reactor, meanwhile, passes into recirculated water and opens cooling reactor stirring and arrange process outward in cooling reactor chuck after residue temperature is cooled to 60 ~ 100 DEG C.
