Problems solved by technology

Although garbage sorting can minimize the garbage that needs to be handled carefully, due to the variety of garbage in our country and the living habits of the people, it is difficult to implement, and even if the garbage is sorted, it is actually now There is also no way to truly realize the timely "harmless, resourceful, and reduction" treatment of organic waste

Embodiment Construction

[0071] In the vast city, each and (attached Figure II ) Residential districts, large and medium-sized enterprises, airports, docks, and stations of the same scale can be Figure one ) And (attached Figure II ) In the form of centralized construction of a processing station to directly transport the generated gas to the city’s gas pipe network to supply residents’ living needs. The produced biomass oil and biomass semi-coke can be recycled and processed in a unified manner.

[0072] This approach can eliminate the urban waste centralized treatment plant.

[0073] The present invention can also follow (attached Figure one ) Centralized implementation in established waste landfills, waste-to-energy plants, and waste sorting plants. However, no matter where it is implemented, it needs the support of abundant biomass energy resources. Unless it is garbage that already contains enough energy or is supported by other more suitable cheap energy sources.

Abstract

Garbage generated in our country has a large amount of household meal residuals, so garbage has obvious characteristics of a high moisture as received (Mar is not less than 50%) and a low lower heating value (Q<dw>ar is not more than 5MJ / kg). A method of increasing biomass energy is employed by the invention. First, garbage is conversed to garbage derivative fuel, and a method of complete isolation from air and external heating is adopted to realize drying, deodorizing, disinfecting and carbonization and pyrolysis of garbage material under a 300-6000 DEG C constant temperature working condition; at last, a rapid condensation method is conducted to rapidly separate condensable gas components and incondensable gas components in gas generated from pyrolysis; and solid materials are separated through an air classification method and answer the purpose intended. According to the garbage treatment method of the invention, no extra processing on the received garbage is needed; and no dioxins or even little secondary pollution is generated; so that various substances in the garbage can be recycled by 100%.

Description

Technical field [0001] The invention relates to a method for the harmless and resource-based treatment of garbage, and belongs to the category of resources and environment. Background technique [0002] The garbage produced in my country has the following obvious characteristics: [0003] 1. There are many household meal leftovers in the garbage, so the received base moisture content (Mar) of the garbage is high, generally Mar≮50%; [0004] 2. Even including several large cities such as Beijing, Shanghai, and Guangzhou, the amount of organic matter in the garbage is low, and the amount of inorganic matter is large. Therefore, not only is the moisture in the garbage high, but also the low calorific value (Q dw ar) is still very low (general Q dw ar≯5MJ / kg), in the process of harmless and resource-based treatment of garbage, even the energy required for drying the garbage itself is not enough, so the extra energy that can be provided to the society by relying on garbage itself is not ...
