GASIFIER FOR THERMAL RECYCLING OF CARBON-BEARING WASTES AND METHOD OF THEIR RECYCLING Russian patent published in 2008 - IPC F23G5/27 F23G5/32 

FIELD: technological processes.

SUBSTANCE: invention is related to recycling of household and industrial carbon-bearing wastes and may be used in communal services for recycling of rubbish with preparation of useful products, such as liquid fuel and oil fractions. Gasifier for thermal recycling of carbon-bearing wastes contains cylindrical casing with sealed reaction space, loading unit installed in the top part of casing, combustion chambers for supply of high-temperature gasifying agents into reaction space, tapered exhaust part of casing equipped with facility for outlet of gasification products. One of combustion chambers is installed into inlet part of gasifier so that jet of high-temperature gasifying agent that outflows from it may affect the wastes that come from loading unit. In area of reaction space gasification open screw channel is provided, which is formed by deflector fixed in internal surface of casing, outside of which in area of screw channel location collector is installed with combustion chambers, which is connected via tangential nozzles that are located along gasification area height to screw channel, above the inlet and at the outlet from which tangential combustion chambers are installed with direction of vortex flow swirling that coincides with direction of screw channel swirling. Under tapered outlet part of gasifier semi-open channel is made in the form of confusor, which is connected to facility for exhaust of gasification products in the form of Venturi scrubber and smoke exhaust. On the dead end of semi-open channel combustion chamber is installed for ejection of gasification products from outlet part and their supply to Venturi scrubber. Method is described for thermal recycling of wastes in this gasifier.

EFFECT: higher efficiency of carbon-bearing wastes gasification.
