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 plant of 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 gasification area of 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. Along the height of reaction space gasification area flow-through sections are provided, which are formed by deflectors in the form of alternating central disk and peripheral annular screens. Central disk screens are fixed on the central body that is common for all sections and is coaxially installed. Annular screens are fixed on internal surface of gasifier with formation of through gaps between disk and annular screens. On casing external surface, in the area of flow-through sections, collector is installed with combustion chambers, which is communicated via tangential nozzles to flow-through sections. Under tapered outlet part of gasifier semi-open channel is made, 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.
