Embodiment Construction

[0027] Refer below Figure 1-Figure 2 A method for co-processing domestic waste and straw according to an embodiment of the present invention is described.

[0028] The method for synergistic processing of domestic waste and straw according to an embodiment of the present invention may include the following steps:

[0029] S1. Sorting domestic garbage to obtain organic matter. In addition to organic matter, inorganic matter such as metals and slag are also sorted out. Sorting can be done by sorting device 1 .

[0030] S2. Breaking the organic matter and the straw into granular form. Among them, due to the difference between the organic matter and the straw, the two can be crushed by crushing devices respectively, so as to obtain their respective granular structures. It can be understood that the size of the granular structure is small, which can facilitate the subsequent pyrolysis treatment. For example, organic matter and straw are crushed to a particle size of 20mm or le...

Abstract

The invention discloses a method for co-treating domestic garbage and straws and a system for implementing the method. The method comprising the following steps: S1, sorting the domestic garbage to obtain organic matters; S2, respectively crushing the organic matters and straws into granular forms; S3, conveying the crushed organic matters and straws into a pyrolysis device for pyrolysis treatmentto obtain pyrolyzed oil gas and pyrolyzed carbon; and S4, separating the pyrolyed oil gas to obtain pyrolyzed oil and pyrolyzed gas, wherein the pyrolyzed gas is used for combustion power generation.Therefore, by using the above method, the purified pyrolyzed gas is fed into an internal combustion engine for power generation, and the solid carbon and the pyrolyzed oil are sold as products. The technological method not only solves the problems of dioxin and fly ash pollutions and the like in the garbage treatment process, but also efficiently utilizes agricultural and forestry waste straws, thereby reducing the operation cost, improving the process economy and facilitating industrial popularization.

Description

technical field [0001] The invention relates to the technical field of solid waste resource treatment, in particular to a method for synergistic treatment of domestic garbage and straw and a system for implementing it. Background technique [0002] Garbage disposal has become another severe environmental problem that our country faces after the energy crisis, water pollution control, and industrial waste disposal. At present, the annual output of municipal solid waste in my country is about 280 million tons, and the accumulated garbage around the city has reached 7 billion tons, covering an area of ​​more than 800,000 mu. About 2 / 3 of the 661 cities are surrounded by garbage. The loss was as high as 30 billion yuan. [0003] Landfill and incineration are commonly used disposal methods for domestic waste. Among them, landfill alone has fallen into the predicament of occupying a large amount of land, poor product sales, and low level of resource utilization. Although incinerat...
