Method for treating solid waste based on a gradient composed of two distinct thermal sources

摘要

A process and system for the treatment of solid waste based on a temperature gradient generated by two distinct thermal sources, notably of a sequenced technological assembly, is able to process solid waste of any class, which operates through a reactor (1) having two chambers (2 and 3), each having a thermal source (4 and 5), where a thermal gradient is generated, followed by a heat exchanger (6) where gases are abruptly cooled and taken to a neutralizing tank (7), for then being directed to an activated charcoal filter (8), due to the action of a blower (9), before finally entering a burner (10) that works under electrical discharges, passing through a catalytic converter (11) and chimney (12) where it is extravasated into the completely inert atmosphere.

1. A process for the treatment of solid waste provided to a processing system, said processing system comprising a reactor (1) configured to operate at a negative pressure, and having first and second chambers (2 and 3) namely a pyrolysis chamber (2) and a fusion chamber (3) for ash and inert material, respectively, said reactor (1) configured to achieve a temperature gradient of between 900° C. to 1600° C. between said first and second chambers (2, 3), said temperature gradient provided by first and second power controlled thermal sources (4 and 5), said first power controlled thermal source (4) coupled to said pyrolysis chamber (2) and serving as a controlled thermal source for said pyrolysis chamber (2), and said second power controlled thermal source (5) coupled to said fusion chamber (3) and serving as a controlled thermal source for said fusion chamber (3), said process for the treatment of said solid waste provided to said processing system comprising:
initiating the treatment of solid waste by said processing system, said step of initiating the treatment of solid waste comprising providing the solid waste to the pyrolysis chamber (2) of said primary reactor (1) in substantial absence of air; subjecting said solid waste to be treated in said pyrolysis chamber (2) to a first temperature established by said first power controlled thermal source (4), said solid waste treated in said pyrolysis chamber (2) at a first temperature undergoing pyrolysis which causes formation of a quantity of gases and ash; establishing a temperature gradient in said primary reactor (1) by establishing a second temperature utilizing said second power controlled thermal source (5) in said fusion chamber (3); removing said quantity of gases from the pyrolysis chamber (2) utilizing a suction device (18); directing said removed gases to a heat exchanger (6); cooling said removed gases utilizing a water circulating via a pump (19) and utilizing air at an external environmental temperature with the aid of a radiator (20); wherein said heat exchanger (6) is configured to condensing oil and water from said removed gases utilizing said heat exchanger (6); directing said condensed oil and water by gravity to a tank (21); injecting said cooled and removed gases into an alkaline water containing tank (7), said alkaline water recirculated constantly with the aid of a pump (22) and filter (23) assembly and cooled in a radiator (24); removing effluent gases from the alkaline water containing tank (7) utilizing a blower (9); directing said effluent gases removed from said alkaline water containing tank (7) through an activated charcoal filter (8); directing said effluent gases from said activated charcoal filter (8) to a combustor (10) having an electrical discharge generator, said electrical discharge generator configured for oxidizing fuel gases contained in said effluent gases; and after said fuel gases contained in said effluent gases are oxidized in said combustor (10), directing remaining effluent gases from said combustor (10) to a catalytic converter (11), said catalytic configured to ensure maximum reduction of NOx, CO and other gases being released to atmosphere through a chimney (12).
