The present patent application, modifies the traditional processing of pyrolysis of waste in general, organic and inorganic compounds, and introduces new systems to greatly improve process reaction speed, improve the cleaning of generated gas and improve the introduction/expulsion of the compound to be treated, obtaining an anoxic cycle (total absence of oxygen except of course for that present in the waste itself) and a continuous cycle, without flues or chimney stacks. The improvements we have introduced allow the process to thermally treat various types of organic (tannery sludge, manure, vegetable/animal biomass, undifferentiated urban solid wastes, leachate etc.) and inorganic (metals, oxides etc.), because the wastes in the particular conditions of molecular dissociation occurring at a set temperature, associated with the introduction of hydrogen which has a 'cicatrizing effect' on the previously dissociated molecules (dioxins, furans), facilitate the formation of natural gas. The process also allows for the recovery of 'dreaded' fine particles which are not airborne but captured in the siphoning liquid and in the water of the final distillation of natural gas. At present, many attempts are being made to try to solve and improve the problem of waste disposal by means of incineration, thermal valorisation and various forms of gasification, with the up-draft fixed-bed, down-draft fixed-bed, fluidized-bed, entrained-flow and entrained-bed gasifiers or with plasma gasifiers etc., but to date the problem has not solved in a definitive manner by such techniques. |
