How to economically and effectively The treatment of rural waste has become a problem that cannot be ignored in rural development. The waste is mainly domestic garbage and sludge generated in wastewater treatment. There are two main ways to deal with these wastes: landfill and incineration. The current There are many deficiencies in the treatment of rural waste. At present, the landfill method is generally used. Although the investment in landfill is small, it occupies a large area and is likely to cause secondary pollution. At present, the incineration method is considered to be the best way to deal with waste. Appropriate methods, although the principles of garbage incineration and sludge incineration are not exactly the same, but they are basically the same in the process of flue gas treatment after combustion. Incineration is the most common waste treatment method at home and abroad. The advantage is that the degree of recycling and reduction of waste is high, and it is the most effective method to make waste harmless, reduce volume, and recycle waste. The incineration method is to put the waste in a high-temperature furnace to fully burn the combustible components. Finally, a method in which the flue gas is treated up to the standard and then discharged through the chimney. However, the current waste combustion heat cannot be fully utilized, and the combustion cost is high, and the waste cannot be completely burned. Therefore, a method is proposed to solve the above problems. Environmentally friendly rural waste incinerator.
