FIELD: chemistry.
SUBSTANCE: processing line apparatus for recycling solid household wastes using thermal decomposition comprises, arranged in series, a loading hopper, a receiving hopper with a loading device, a station for sorting solid household wastes linked to a magnetic separator for selecting magnetic metals from the incoming waste mass, a station for crushing solid household wastes linked to a conveyor for loading crushed material into a thermal treatment unit which is linked to means of unloading a carbonaceous solid residue after thermal treatment and feeding into an ash hopper. The thermal treatment unit for the thermal decomposition of the crushed material is a container with a loading hatch, inside of which there is at least one combustion chamber with a tubular pyrocoil extending therefrom, which is heated by the combustion heat of fuel gas on burners for heating wastes in an oxygenless medium until decomposition thereof due to the radiation of heat generated by the burner flame in the combustion chamber, and heat transfer with flue gases into the pyrocoil. The container is fitted with outlets for releasing the pyrolysis gases formed during the decomposition of wastes towards the first heat exchanger for primary cooling of the pyrolysis gases and collection of liquid fractions into a separate container, followed by redirection into a filtering unit for separating the end product from tar, and towards the second heat exchanger for the separation of liquid fractions condensed from the pyrolysis gas on plates and outputting through separate pipes the separated liquid fractions into separate storage containers, one of which is linked to the said filtering unit.
EFFECT: simple design of the apparatus.
