Plasma waste incineration device and method

Abstract

The invention provides a plasma waste incineration device and method. The plasma waste incineration device comprises a power supply system, an electro-arc heater, a working system and a PLC control system; the incineration temperature reaches 850 to 950 DEG C during working, thus various bacteria in domestic waste can be effectively and fully eliminated, toxic and harmful components can be decomposed into nontoxic and harmless materials under the effect of high temperature, and as a result, the waste pollution can be reduced, and the environment can be protected; the social benefit is increased, and the policies on new energy, environmental pollution, zero-carbon emission and sustainable development can be met. The plasma waste incineration device and method have the advantages that the operation is convenient, the heat efficiency is high, and the working is stable.

Description

【Technical field】 [0001] The invention belongs to the field of waste treatment, and relates to a plasma incineration garbage equipment, in particular to a plasma incineration garbage equipment and a method thereof. 【Background technique】 [0002] At present, there is an increasing amount of hazardous waste and plastic waste from industries and special industries, and this type of waste is the most difficult to dispose of. my country's domestic waste, hazardous waste and plastic waste are mainly disposed of by landfill and incineration. Landfill not only occupies a large amount of land, but also pollutes groundwater. Although the incineration method has a high volume reduction ratio and can recover energy, it is strongly opposed by the public because of the environmental pollution caused by dioxins produced during the incineration process. There is an urgent need to develop a new generation of green, energy-saving and consumption-reducing alternative incineration technologies...

Problems solved by technology

[0009] In view of the various advantages of plasma technology, the plasma system has been widely used in the field of waste incineration. In the existing plasma waste incineration equipment, AC arc heaters or DC arc heaters are generally used. If AC arc heaters are used, although The power supply system has a simple structure and low investment, but it has inherent defects and low thermal efficiency; if a DC arc heater is used, it can provide voltage and current in a constant direction, and achieve long-term contact between the airflow and the arc, and the enthalpy of the outlet airflow is high. But the disadvantage is that it needs to increase the flow conversion device, the investment is large, and the control is complicated; this causes the incineration equipment to work unstable during the waste incineration process
