Closed chamber Destruction with plasma and ionization techniques at OXYGEN STARVED condition. The decomposition temperature is around 350 – 450oC depends on the solid waste input. Do not require electric, other power or fuel for organic substances for decomposition
PROCESS
Waste has to be feed into the chamber of equipment on uniform intervals. At the initial stage requires start up fire by using camphor/Dry wood afterwards destruction starts slowly by splitting the molecules into atoms. These atoms further ionized as electron, proton and neutron and this state is called as"plasma state" and separated electron change to "accelerated electron" with strong energy.
On the other side a small amount of atmospheric air is allowed to pass through strong magnetic field into Oxygen starved chamber. During this operation oxygen molecule split into elemental oxygen with negative charge. This atomic oxygen is to oxidize perfectly organic surface and change organic matter to desperate organic oxide. Therefore reaction is induced by exothermic phenomenon, thermal condition around 200oC is needed to accelerate reaction which can achieve by initial decomposition.
From 200oC (by initial firing) to 350~450oC in the equipment by plasma, ionization and thermal vibration will achieve. The decomposition of waste takes place on bed wise so that heat energy developed may not be continuous. At the bottom of the destruction chamber a tubular type radiator which makes buried near the lower layer of deposited ash and ash will be separated. The waste heat is recovered through a tubular heat sink arranged near the upper layer of deposited ash of a hearth center section of said combustion chamber and said hearth periphery and the entire structure will have good heat transfer potential. The waste heat is recovered back and supply to the wet waste where the moisture content is reducing phenomenally.
The flue gas emission from the decomposition chamber is releasing with natural draft. The emission may contain some toxic components like Dioxin and Furan, Heavy metals, Nitrogen Oxides etc.,. The toxic components are destructed by using the external heating chamber with the heat of 850oC followed by wet scrubber by which can reduce substantially from 850oC to 180oC. During this process we can eliminate the reformation of Dioxin and Furan occurs and the clean gas is dispersing into atmosphere.
The non combustible waste and ash (inorganic) is collected separately and stored in well defined area for the disposal into Secured landfill. The ash quantity generation should be in the ratio of 1/300.
SOLUTION TO AIR POLUTION
It has been suggested that one of the causes of dioxins in an incinerator is the retention of oxygen due to imperfect combustion and low processing temperature (300–350°C). Consequently, it became mandatory to process waste at high temperatures, at 800°C or higher, which requires installation of a secondary combustion system.
On the other hand, SWATCH Decomposition system processes waste at low temperatures; however, thec
generation of dioxins is inhibited. Why…How?
The answer is because it hampers the bonding of two benzene rings with oxygen by minimizing the supply of oxygen. The system also inhibits the benzene rings themselves from being produced by utilizing the effect of anions which are generated when the waste passes through the Special magnetic device and enters a chamber. |
