    • Device for thermal destruction of polyethylene and polypropylene waste includes a polymer raw material heating unit, a pyrolysis furnace and a reactor of polymeric raw material thermal destruction, with devices of raw material loading and coke unloading, a unit for fractionating the destruction products of polymer raw material, a unit of heat exchangers, equipment for performing thermal catalysis over a catalyst, as well as the supply unit with pipelines for the cooling agent in the form of water circulating. When operated in a periodic plastic waste processing mode, the device contains no less than two thermal destruction reactors. These reactors are connected in parallel with the provision of a full technological cycle "heating - thermal destruction - cooling - coke unloading - raw material loading". Each of the reactors, or one of them, is equipped with a portable or removable furnace. The furnace is made with the possibility of detachment from the reactor or joining to the reactor. The unit for fractionating the polymer raw material destruction products consists of a series-connected heat exchanger with water cooling, hydrocarbons collecting tank with a boiler, a dewaxer, a rectification column for separating diesel fuel and gasoline fractions, and a boiler, installed in the column cube, a tubular vertically installed heat exchanger with a downward movement of gasoline vapor and hydrocarbon gas. The circuit of countercurrent motion of the phases with a descending flow of a vapor-gas mixture of hydrocarbons is implemented in the heat exchanger with water cooling. Dewaxer consists of a packed bottom and a dephlegmator. Rectification column for separating diesel fuel and gasoline fractions consists of a packed bottom and a dephlegmator. Dephlegmator is installed at the top and configured as a shell-and-tube heat exchanger. As a catalyst, the device contains a heterogeneous catalyst in the form of titanium strands twisted in spirals. Each spiral is preturned in one or in different directions. Titanium strands are placed in the collecting tank, in the tubes of the heat exchanger, where high-boiling components of a vapor-gas mixture are condensed, in the tubes of the dewaxer dephlegmator and in the tubes of the rectification column dephlegmator.
