The utility model relates to the technical field of light component removal equipment, and discloses a heat-sensitive substance light component removal device which comprises a preheater, and the output end of the preheater is fixedly connected with a first connecting
pipe. When the equipment is used, materials are preheated and pressurized and then enter the light component removal
tower in a negative pressure state,
flash evaporation occurs due to pressure change, most of light components upwards pass through the packing layer and the built-in condenser and then enter the light component condenser, heavy components downwards flow into the heater tube
nest, and a small amount of remaining light components are removed through heating
evaporation; heavy components are discharged from the bottom of the light component removal
tower, on one hand, a large amount of light components are removed at low temperature through
flash evaporation, the
retention time of materials in the heater is short, side reactions of heat-sensitive substances are reduced, the yield is improved, in addition, a filler layer on the upper portion of the light component removal
tower accelerates heat exchange and promotes separation of the light components and the heavy components, and a built-in condenser adjusts
backflow of the entrained heavy components; the light components are thoroughly removed, the purity is high, side reactions of heat-sensitive substances are few, the yield is high, and the purity of the light components is high.
