At present, most garbage disposal is mainly landfill, accounting for more than 70% of the total disposal volume. Most countries in the world, especially underdeveloped countries, use this method for most garbage disposal. This method is characterized by low construction and operation costs, simple operation, and large processing volume. However, there are also many disadvantages: First, it occupies a large amount of land, difficult to select a site, and high land acquisition costs; second, it wastes a large amount of garbage-containing resources, artificially turning garbage into "resources that cannot be increased and huge wealth thrown away", which cannot meet the needs of resource processing; third, it causes serious environmental pollution. Because most of the existing landfill construction does not meet the requirements of sanitary landfill, the bacteria and toxins in the garbage continue to seep downward, polluting the land and water quality, and with the increase in accumulation and the continuation of time, the pollution spreads to the surrounding areas and deep underground, leaving harm for thousands of years, and the toxic and smelly gases emitted by the garbage spread to the surrounding areas, forming three-dimensional pollution in the air, surrounding areas, and underground. Although a few "sanitary landfills" have been built in many developed countries and some more developed cities in my country, reducing some pollution, there are still many environmental pollution problems caused by technical imperfections, and the problem cannot be fundamentally solved.
Therefore, the advantages of
garbage sorting equipment are highlighted. Use garbage sorting equipment to process domestic garbage as resources, accurately classify urban domestic garbage, and then use appropriate methods to treat it according to the different properties of the classified garbage, so that it can be recycled and reused, thereby truly making the garbage harmless and reducing the amount, turning harm into benefit, and at the same time reducing human demands on natural resources and realizing sustainable use of resources. Therefore, the development prospects of garbage sorting equipment are very promising.
After years of research and development, we have designed a fully automatic mechanized garbage sorting system that can handle a variety of garbage. When treating garbage, various urban and rural garbage can be sorted into the following categories after uniform garbage feeding, automatic large garbage sorting system, large garbage crushing system, automatic bag breaking of bagged garbage, automatic crushing system of large organic matter, air separation system, magnetic separation system, particle separation system, high temperature and high pressure hydrolysis and hydrothermal oxidation "hot selection" system of organic matter, etc.:
1. Inorganic matter; 2. Sand and soil; 3. Organic matter;
4. Non-recyclable combustible matter; 5. Film plastic; 6. Ferromagnetic matter;
The sorting purity of the above garbage can reach more than 85%, and the sorting rate of film plastic garbage can reach more than 90%, which lays a solid foundation for the "resourceization and industrialization" of garbage treatment in the next process. At the same time, it can also reduce the amount of garbage incineration by nearly four-fifths, and there is no need to add coal or spray oil. The waste heat generated by the incinerator is provided to the hydrolysis tank to treat organic matter. The garbage sorting equipment is used to treat garbage, and the operating cost saved is considerable.
