Long-life high-temperature plasma torch medical waste harmless treatment system

Abstract

The invention discloses a long-life high-temperature plasma torch medical waste harmless treatment system. Medical waste is crushed and transmitted to a main combustion furnace through a waste feedingsystem. The main combustion furnace burns from top to bottom, after the medical waste enters the main combustion furnace, the medical waste is incinerated by two layers of plasma guns installed circumferentially in the main combustion furnace; waste gas generated by incineration enters a auxiliary combustion furnace for further incineration, the finally generated tail gas enters a tail gas treatment system for purification and then is discharged through an induced draft fan; and normal temperature air is subjected to heat exchange with the tail gas generated after secondary incineration in the auxiliary combustion furnace through a heat exchanger, and the heated air is introduced into the upper part inside the main combustion furnace. An air supply system is used to supply hot air to themain combustion furnace or normally warm air to the auxiliary combustion furnace. According to the long-life high-temperature plasma torch medical waste harmless treatment system, harmless treatment of medical waste garbage can be completely realized, and meanwhile, heat energy of combustion substances can be utilized to generate electricity or be recycled to participate in baking and secondary combustion, thus achieving the purposes of energy conservation and emission reduction.

Description

technical field [0001] The invention relates to the field of hazardous solid waste treatment, in particular to a long-life high-temperature plasma torch harmless treatment system for medical waste. Background technique [0002] With the continuous increase of domestic garbage in my country, the situation of garbage siege is becoming more and more prominent, and it poses a serious threat to environmental safety. In order to protect the homeland and achieve sustainable development, my country has attached great importance to environmental protection in recent years, and urgently needs to develop a new generation of energy-saving and environmentally friendly waste disposal technology. [0003] Traditional municipal solid waste and other domestic waste are treated mainly by sanitary landfill, supplemented by composting and incineration. Landfill is recognized as the last choice for waste disposal because it takes up a lot of space and pollutes groundwater; although composting c...

Problems solved by technology

[0006] The present invention aims at the difficult harmless treatment of medical solid waste, excessive flue gas of combustion products, easy generation of secondary pollution such as dioxin and heavy metals, etc., and at the same time aims at the short working life of the plasma torch, and proposes a long-life high-temperature plasma torch The harmless treatment system for medical waste can completely realize the harmless treatment of medical waste. At the same time, the thermal energy of the combustion can be used to generate electricity or be recycled to participate in baking and secondary combustion, so as to achieve the purpose of energy saving and emission reduction
