Description:
A SYSTEM AND METHOD FOR TREATMENT OF WASTE MATERIALS

TECHNICAL FIELD OF THE INVENTION:

[001] The present invention generally relates to a system and method for the treatment of MSW and other organic waste materials. More particularly, the present invention relates to treatment of MSW organic waste - hospital waste, pharmaceutical waste with mixed chemicals and mixed waste which can be destroyed without creating or producing harmful emissions.

BACKGROUND OF THE INVENTION:

[002] Most of the waste produced from the Industries, homes and some private organizations are generally released into small nullahs, canals, rivers and seas without treatment, otherwise, dumped in ground; which result in the environmental pollution which is a serious Hazard to the ecosystem. Most of the materials used for the preparation of any pharmaceutical products or any chemical residue or medicinal waste or routine household items are non-bio-degradable in the soil, which is serious threat to the ecological balance of the environment. The treatment of such waste from industries or homes or any organizations, needs to be done, prevent damage to the ecosystem. The treatment should be in such a way that it should not produce harmful emissions resultants and it has to achieve in economical way and also has to achieve by using low amount of resources.

[003] In daily household waste comprises mostly of the organic waste and dry organic & inorganic materials which are simply dumped in aforesaid routes without processing it in a safe way. The Pharmaceutical industries for the manufacture of drugs or pharmaceutical products not limited to any category requires more no of Chemicals along with many additives which results in to an API or a formulation. But the resultants or by products are released directly in to aforesaid routes without processing them in a safe way and not converting them in to a safe products and most of these released materials are annihilate the environment. Not limited to above cases most of the materials used in daily life, whether related to domestic or in any organizations are simply dumping without processing them in safe ways.

[004] Waste material or garbage is also destroyed by incineration, which too, results in the generation of harmful gases released to cause air pollution. Incinerators also it requires large space which in space starved cities or towns is not feasible. [005] In the present scenario the growth of industries in any field is unstoppable as it is required to improve the standards of human beings.

[006] Even though government might be taking the steps to decrease the waste generated in all industries and to divide the waste in to different types, but all these measures are not sufficient to put an end to the pollution caused by the waste to ecosystem. And also the processing of waste burning without releasing harmful effluents is not achieved by the present available processes.

[007] Most of the nations are simply burying the waste, where the degradation will not be achieved accurately. Many nations are recycling the waste but the percentage of recycling very low and the remaining amount of waste is simply burnt or used as landfill, which results in the pollution of the environment.

[008] So as to overcome the above problems, the government stopped burying food wastes namely, according to the regulations, only residuals produced after incineration, compost treatment or extermination could be buried, so that the organic materials can be treated based on incineration and recycling methods.

[009] The proposed recycling methods are may not be economical and they may produce different pollutants.

[010] W02004/072208 relates to a method and a device for continuous conversion of organic waste into sin gases like H2 and CO. More specifically, it relates to treating highly contaminated waste products and worn-out vehicle tires in which the charge is liquefied and then cracked giving a product in the gaseous phase, wherein the charge is introduced in to a hot bath, comprising liquid inorganic medium, displaced through the melting zone and the decomposition zone and then the gaseous products of the decomposition are collected at the top and the impurities are removed by means of at least one conveyer. The decomposition reactions are carried out catalytically in the liquefied layer of the charge formed on the surface of the hot bath comprising liquid inorganic medium.

[Oil] US9518733B1 discloses a furnace apparatus to incinerate solid waste comprising a chamber, a solid waste feed inlet, air inlet pipes and air outlet pipes. The air inlet pipes receive air for combustion of the solid waste within the lower combustion section. The air outlet pipes exhaust combusted air from the lower combustion section, where multiple wigglers are operably attached on the air inlet pipes and the air outlet pipes. The paramagnetic oxygen present in the received air is concentrated via the wigglers, and the concentrated oxygen is introduced into plasma generated within the combustion section to accelerate the combustion process, and to oxidize toxic matter present in the solid waste. A dry scrubber used to remove toxins from flue gases is used.

[012] The methods and systems presently available in the market for thermal decomposition treatment of waste materials, but all are limiting some extent and producing harmful materials in to the environment and also they are expensive and require high amounts of power supply.

[013] Hence in the light of the aforementioned discussion, there is a need of a system and a method for treatment of waste material to decompose such as garbage, inert waste and Pharma waste, without producing harmful chemicals in to the environment.

OBJECTS OF THE INVENTION:

[014] The main object of the present invention is to provide a safe system and method for treatment of waste to decompose the waste material such as garbage, inert waste and Pharma waste, without producing harmful effects to the environment.

[015] It is another object of the present invention to provide the method and system for thermal decomposition treatment waste to decompose of waste material such as garbage, inert waste and Pharma waste completely, in affordable price and in different sizes based up on the need and also using very low amounts of power supply.

[016] According to an aspect of the present invention, a system for treatment of waste materials, said system comprising at least one chamber provided with a charge feed door for feeding unsegregated waste materials into said chamber through chute at a predetermined time interval for treating waste materials, where the resident heat aids the magnetized ionized air to react with the hydrocarbons in the waste materials, a resultant exothermic reaction boosts the temperature to 350 - 400°C. The waste in the absence of air or free oxygen starts by splitting the molecules into atoms and is de-hydrated & reduced to Ceramic Ash. The heat induced by exothermic reaction phenomenon is retained in the system through a plurality of heating coils to generate heat and retain it to said chamber and waste heat is recycled through a tubular heat sink, where the recycled heat is supplied to wet waste material to reduce the moisture content, thereby increasing the efficiency or productivity of the machine. A separate chamber for collecting and separating ash deposited after the treatment of waste material, where at the upper layer of said radiator said heat sink is arranged at a hearth center section of said chamber to attain uniform heat transfer throughout the process of waste material treatment; a flue gas exhaust from said chamber is relayed through a dual or triple stage scrubber to remove toxic elements by spraying water or dilute solution and then released through a chimney into the atmosphere. The exhaust gases are actually heated in a separate area to 900 degrees centigrade to remove all toxins and dioxins from flue gas during scrubbing process. This processing of exhaust gas helps in reducing formation within the machine greatly, whereas multi-stage process of said scrubber removes toxins & dioxins from flue gas. This is to increase efficiency of the system & availability of the machine during practical application. The machine thus uses electricity back up only for the recirculation pump & heaters used for gas cleaning. This is entirely to confirm to the Air Pollutions norms; the waste reduction process is completely self-sustaining does not require any fuel or electricity support, therefore the operating cost is extremely low, therefore can be easily deployed in remote areas.
