Description

Technical Field

[0001] The present invention relates to the technical field of dry garbage treatment, and in particular to a mobile dry garbage pyrolysis device and method for use in places with dense human traffic. Background Art

[0002] With the acceleration of urbanization and increasing population density, the amount of dry waste generated in densely populated urban public spaces such as parks, squares, and commercial districts has shown a significant upward trend. This dry waste primarily consists of paper, plastic bottles, and packaging bags, and its generation is particularly high during holidays and major events.

[0003] Currently, waste disposal in parks and other places primarily relies on centralized collection and transportation at waste transfer stations. However, during peak periods, this model often exposes problems such as inefficiency, limited transfer capacity, and secondary pollution. During peak periods, waste transfer vehicles may be unable to promptly remove waste, leading to waste accumulation. This not only affects the city's appearance and environment, but can also breed bacteria, produce odors, and even pose public health risks.

[0004] Traditional waste disposal methods have many limitations. For example, landfills occupy large amounts of land and are prone to soil and groundwater contamination. Incineration requires the construction of large-scale incineration facilities, which is costly, complex to operate and maintain, and can produce harmful gases. Therefore, pyrolysis is an effective treatment method.

[0005] For example, the invention with publication number CN105385465A discloses a garbage pyrolysis device and method, which includes a garbage pyrolysis mechanism, a water vapor condensation system, a residual carbon collection mechanism, a combustible gas combustion furnace, a waste heat utilization system, and an exhaust gas treatment mechanism. The garbage pyrolysis mechanism includes three groups of fixed-bed pyrolysis reactors, which are respectively in the discharge and feeding, drying, and pyrolysis working stages. After the feeding is completed, a large amount of hot air is first introduced to complete the drying, and the water vapor enters the water vapor condensation system; then an appropriate amount of hot air is introduced to complete the pyrolysis, the pyrolysis gas enters the combustible gas combustion furnace, and the residual carbon enters the residual carbon collection mechanism; the waste heat utilization system uses the heat of the flue gas to heat the cold air, and the hot air is used for drying and pyrolysis of the garbage; the exhaust gas enters the exhaust gas treatment mechanism. Using the above-mentioned device to carry out garbage pyrolysis can effectively avoid the generation and emission of harmful substances such as dioxins, and realize the harmless treatment of garbage; at the same time, the heat generated by the combustion of the pyrolysis gas is used to complete the drying and pyrolysis of the garbage, basically realizing the self-heating pyrolysis process of the garbage.

[0006] However, this technology is aimed at fixed garbage disposal devices for large-scale garbage disposal in garbage plants. The device structure is complex and large in size, and it is based on incineration to dispose of garbage. The investment cost is high and the subsequent operation and maintenance are difficult.

[0007] In summary, existing waste disposal systems typically use fixed incinerators to process waste. These devices are large and difficult to maintain. Furthermore, for locations where waste is dispersed, the initial waste collection effort is extensive, consuming significant manpower and resources, and waste easily accumulates. This makes them unsuitable for densely populated areas.

[0008] Therefore, it is necessary to provide a mobile dry garbage pyrolysis device and method that has a simple structure, convenient operation and maintenance, and can be moved anytime and anywhere for use in places with heavy traffic. Summary of the Invention

[0009] The purpose of the present invention is to overcome the defects of the above-mentioned prior art with fixed treatment structure, such as cumbersome early garbage collection, inability to clean up in time, easy to cause garbage accumulation, affecting environmental sanitation, and large size and inflexible use, and to provide a mobile dry garbage pyrolysis device and method for use in places with heavy traffic, which is designed to quickly process dry garbage on site, reduce garbage accumulation, and improve garbage treatment efficiency.
