DEVICE FOR THERMAL DESTRUCTION OF WASTE FROM POLYETHYLENE AND POLYPROPYLENE Russian patent published in 2017 - IPC C10B53/00 C10B53/07 

FIELD: chemistry.

SUBSTANCE: apparatus for thermal degradation polyethylene and polypropylene wastes include thermal decomposition reactor 1, fractionating the degradation products node unit heat exchangers, equipment for the implementation of thermal catalysis supply unit with refrigerant piping. The reactor is provided with thermal degradation mobile furnace 2. The furnace is configured to disconnect from and attachment to a reactor. Node fractionating degradation products consists of series-connected heat exchanger 6, the cube-collection hydrocarbons with boiler 7, 8 dewaxer, distillation column 15 for separating fractions of diesel fuel and gasoline, a vertically mounted tubular heat exchanger 18 with the descending motion of gasoline vapor and a hydrocarbon gas. The distillation column consists of the bottom of the packed reflux condenser 14 and installed in the upper part. Dewaxer 8 consists of a packed bottom. In the heat exchanger with water cooling, the scheme of countercurrent movement phase downflow hydrocarbon vapor mixture is implemented. The apparatus comprises a heterogeneous catalyst in the form of strips of titanium, twisted into a spiral. The strips of titanium are placed in the cube-collection, the tubes in the heat exchanger, wherein the condensed high-boiling hydrocarbons from the vapor mixture, in tubes dewaxer reflux condenser and dephlegmator tubes fractionator.

EFFECT: energy efficiency utilisation of organic raw process.
