FIELD: technological processes.
SUBSTANCE: invention relates to processing of organic substances as mono-composition, and raw materials of complex composition, namely to method of high-temperature ablation pyrolysis. Method of organic raw materials processing includes stages, at which raw material is ground and dried, after which raw material is supplied into hopper-cyclone with lower conical part, where air is separated from raw material, from the lower part of the cyclone bunker, the solid part of the raw material enters the horizontal screw, from wherefrom the raw material is supplied to the lower part of the vertical spiral auger, after which the raw material is supplied to the pyrolysis reactor raw material feed chamber. Reactor has elongated body of vertical arrangement with inclination relative to vertical, divided by wavy plate into two isolated from each other heating zone and pyrolysis zone. Heating zone is flow chamber of flue gases coming from burner arranged in upper part of reactor. Pyrolysis zone is a pyrolysis chamber into which raw material is fed, which is subjected to pyrolysis under heating from the heating zone of the separating plate and guide ribs arranged on the inner surface of the pyrolysis zone. Smoke gases, passing along the whole reactor through the heating zone, are removed through the smoke exhauster located in the lower part of the reactor, and the solid residue, which is pyrolysis coke, is supplied through the outlet in the lower conical part of the reactor to the horizontal coke discharge auger, from where it comes from below into vertical auger, is run to its upper part and is transmitted to tight accumulating hopper of coke. Produced gas in the pyrolysis chamber by means of the gas vortex compressor at the end of the process filtration line is supplied to the cooling and separation apparatuses to obtain syngas which, after cleaning, is supplied to the consumer, and excess is burnt in the emergency flare.
EFFECT: invention allows uniform distribution and heating of raw material by natural (gravitational) method, intended for processing, and obtaining high-quality carbon product with maximum removal of volatile compounds, subject to further activation and production of activated carbon.
