1. The main equipment is mostly patented equipment developed after years of field experience and practice verification, with low failure rate and good use effect, which is especially suitable for the treatment of domestic garbage in China. In the process of garbage disposal, the energy consumption is less, and the comprehensive power consumption per ton of garbage is 30-40 degrees. No water, energy recycling. The treatment cost is much lower than other treatment technologies. The social and economic benefits are good, and the output is far greater than the input.
2. Turn waste into treasure. Every year, 4 billion plastic fast food boxes, 50-70 billion instant noodle bowls and disposable chopsticks 10 billion pairs are used, accounting for 8- 15% of domestic garbage. One ton of waste plastics can be reprocessed with 600 kilograms of diesel oil. Recycling 1500 tons of waste paper can save trees used to produce 1200 tons of paper. 30%-40% of domestic garbage can be recycled, and this meager profit resource should be cherished. The garbage incinerator is environmentally friendly and saves resources.
3. Save land. Recycling is a good way to solve the garbage problem. Garbage incineration saves land, avoids the pollution caused by landfill, and can also turn waste into treasure. Waste incineration can reduce the number of waste treatment and treatment equipment, reduce the treatment cost and reduce the consumption of land resources, which has social, economic and ecological benefits.
4. Reduce land occupation. Some substances in domestic garbage are not easy to degrade, resulting in serious soil erosion. The garbage incinerator can burn garbage, reducing the amount of garbage by more than 80%; At present, sanitary landfill or even simple landfill is mostly used for garbage disposal, covering an area of tens of thousands of mu; Insects and flies, sewage flooding, stinking, seriously polluting the environment. Waste batteries contain toxic substances such as mercury and cadmium, which will cause serious harm to human body; Waste plastics in soil will reduce crop yield; The discarded waste plastic is eaten by animals, which leads to the death of animals.
It is reasonable and feasible to develop an inclined reciprocating pusher grate incinerator by analyzing the characteristics of various municipal waste incineration equipment and combining with China's national conditions. In the design, besides the heat transfer efficiency of heating surface, the corrosion and wear of heating surface and furnace wall, flue gas purification and automatic control should also be considered. The characteristics of low calorific value and high moisture of municipal solid waste in China should be fully considered in the design of furnace arch and hearth and the arrangement and distribution of combustion-supporting air. Considering the actual situation in China, while developing large-scale waste boilers and building large-scale waste incineration plants, we should encourage the development of small and medium-sized waste incineration equipment.
