Method for gas pressure pipeline collecting, transporting and classifying of urban garbage

Abstract

The invention relates to a method for gas pressure pipeline collecting, transporting and classifying of urban garbage. The urban garbage is put into a throwing system through a garbage throwing port,then the garbage is transported from a transportation pipeline to a garbage separation and classification system by using gas pressure, and finally, the garbage in the garbage separation and classification system is subjected to a mode of gas-solid separation through a garbage separator, magnetic separation of a magnetic separator and air separation of a air separator, metal substances, waste paper waste plastics, other garbage and generated waste gas from the garbage are separated; and metal substances and the waste paper waste plastics are dried and compacted to be transported to a garbage treatment plant for further treatment, the other garbage is compacted after drying to be transported to the garbage treatment plant for further treatment, the waste gas is delivered to a filtering device for filtering, and then the waste gas is discharged. The secondary pollution is avoided in the transportation process of the urban garbage, the labor intensity of the garbage collection is reduced,and the working environment of environmental protection workers is optimized.

Description

technical field [0001] The invention relates to a method for collecting and transporting urban garbage, in particular to a method for collecting, transporting and classifying urban garbage through pneumatic pipelines. Background technique [0002] In recent years, with the rapid development of my country's economy and the continuous acceleration of urbanization, the scale of cities has been expanding, the urban population has been highly concentrated, and the level of national consumption has continued to increase, which has led to a sharp increase in the output of urban domestic waste. According to China's urban environmental sanitation Association statistics, my country produces nearly 400 million tons of municipal solid waste every year, with the acceleration of my country's urbanization process and the improvement of people's living standards, urban solid waste is still increasing at a rate of 5%-8% per year, and the growing life Garbage not only causes serious pollution t...

Problems solved by technology

[0004] According to the above background content, the object of the present invention is to provide a method for collecting, transporting and classifying urban garbage through pneumatic pipelines, which uses the airflow formed by negative pressure technology to transport the garbage scattered everywhere to the garbage collection through the underground transportation pipeline. The sorting treatment station, through gas-solid separation, magnetic separation, winnowing, compression and sealing, sorts the garbage and transports them away by garbage trucks, solving the problems of low efficiency of urban garbage collection and transportation, consuming a lot of manpower and causing great environmental pollution. At the same time, The system can automatically separate the metal and non-metal materials in the garbage through magnetic separation, and the recyclable materials in the non-metal materials such as waste paper and waste plastic can be sorted out through winnowing, and the separated garbage can be compressed and packaged separately. In different containers, they are transported away by garbage trucks, metal materials, waste paper, waste plastics and other recyclable materials are directly transported to the recycling department, while other wastes are directly transported to the waste disposal site, effectively reducing the cost of manual collection, transportation and sorting
