Garbage treating method

Abstract

The invention discloses a method for treating garbage, which comprises the following steps: 1) loading garbage into steam reactors in steam reactor groups; The water supply tank is sent to the steam boiler to generate steam; 3) The steam enters the steam accumulator, and the steam accumulator sends the steam into the steam reactor; 4) The steam fully treats the garbage; 5) The treated garbage Send to the screening device for screening. The system of the present invention uses high-pressure and high-temperature steam to process garbage, and screens and separates the generated garbage, which can convert waste into organic fuel, building materials, heat insulation materials, compost, etc., increases recycled materials, and reduces the impact on supersaturated heaps. The pressure of land filling, the whole device does not burn during the process of garbage disposal, and realizes zero emission and zero pollution.

Description

technical field [0001] The invention relates to a garbage disposal method. Background technique [0002] Rapidly evolving from poverty to wasteful consumption, China has surpassed the United States to become the world's largest producer of household waste. 670 cities and towns in China discarded a total of 135 million tons of garbage in 2008. The country produced a total of 260 million tons of garbage, which is equal to one-third of the world's total garbage. Urban garbage is growing at a rate of 4.8% per year. With the urbanization of the population, it is estimated that by 2020 By 2020, 60% of China's population will live in cities, accelerating and deepening the garbage problem. Living conditions have improved, commodities have been optimized, and the combination of garbage has also changed to a great extent. Since 1990, the dust and sand in urban garbage has dropped from 50% in the past to less than 10% now. The fastest increasing is recyclable materials; today's waste...

AI Technical Summary

Problems solved by technology

[0003] The existing waste treatment technologies are mainly divided into the following categories: (1) Landfill: The traditional method of waste disposal is to landfill the waste, but with the increase of the amount of waste and the expansion of the city, the landfill requires an increasing amount of landfill. The land, the formed garbage surrounds the city, hinders the development of the city, and the harm of landfill becomes more obvious.

(2) Incineration: The chemical composition of waste gas produced by waste combustion in modern cities is complex, and many of them contain toxic components. It is very expensive to filter the discharged toxic gas

Due to the practical difficulty of raising large volumes of waste to the plasma level, this method is still in the experimental stage
