Organosilicon non-condensable tail gas conversion recovery system and recovery method

The invention discloses a conversion and recovery system for non-condensable organic silicon tail gas, and belongs to the technical field of tail gas treatment. Comprising a double-effect heat exchanger, a feeding preheater, a fixed bed reaction kettle and a discharging cooler, a tube pass discharging opening of the double-effect heat exchanger is connected with a feeding opening of the feeding preheater, and a discharging opening of the feeding preheater is connected with a feeding opening of the fixed bed reaction kettle; a discharge port of the fixed bed reaction kettle is connected with a shell pass feed port of the double-effect heat exchanger, and a shell pass discharge port of the double-effect heat exchanger is connected with a feed port of the discharge cooler. The organic silicon non-condensable tail gas is subjected to heating treatment, the treated organic silicon non-condensable tail gas reacts with hydrogen chloride to generate chlorosilane with high additional value, meanwhile, the tail gas tre
