FIELD: chemistry.
SUBSTANCE: invention relates to a method and device for pyrolysis of domestic waste in rural areas. Device comprises an external pipe, a middle pipe and an internal pipe, which are arranged in series one into another, wherein inner pipe forms first channel for gaseous combustion products flow, space between inner pipe and middle pipe forms pyrolysis chamber, and the space between the middle pipe and the outer pipe forms a second channel for the combustion gases flowing. On outer surface of inner pipe there is an auger configured to push wastes along screw trajectory forward. A helical deflector is installed on the external surface of the middle pipe so that in the second channel the gaseous combustion products flowed along the screw trajectory provided by this screw deflector. Flow of high-temperature gaseous combustion products flowing through two channels transfers heat to pyrolysis chamber by heating waste therein; pyrolysis of said wastes is carried out through a pyrolysis chamber with auger.
EFFECT: products formed during pyrolysis can be used, in particular, burnt, as a result of which high-temperature gaseous combustion products can be obtained, which can be used not only for drying wastes and pyrolysis thereof, but also in household, industry or agriculture.
