Problems solved by technology

[0004] The disadvantage of the above method is that the domestic waste has not been dried, and all the water in the waste is vaporized and then enters the rotary kiln system, resulting in an increase in power consumption

Embodiment Construction

[0030] Such as figure 1 As shown, the combined process of municipal waste pretreatment and comprehensive utilization of cement kiln resources includes the following steps:

[0031] 1) After the municipal waste is measured and radioactively detected, it enters the waste receiving system (that is, the municipal waste receiving system);

[0032] 2) Pre-shredding: The municipal waste received by the waste receiving system is sent to the pre-shredding system, first crushed by the crusher, and then the crushed waste is sent to the storage pit, and the Fe metal is separated by a magnetic separation device during the transportation process to obtain crushed waste. Garbage; the pre-crushing system includes a crusher, a magnetic separation device and a storage pit (such as figure 2 shown);

[0033] 3) Utilize drying treatment system (such as image 3 As shown, that is to use aerobic fermentation) to dry and stabilize the broken garbage: transfer the broken garbage in the storage pit...

Abstract

The invention relates to a linkage process of municipal waste pre-treatment and cement kiln resource comprehensive utilization and a system thereof. The linkage process of municipal waste pre-treatment and cement kiln resource comprehensive utilization is characterized by comprising the steps as follows: 1 municipal waste enters a waste receiving system after measurement and radioactivity detection; 2 the municipal waste is crushed in advance; 3 crushed waste is dried and stabilized through a drying treatment system; 4 dried waste is treated in mechanical mode through a mechanical treatment system; and 5 separated flammable materials are refined by a refining system, measured by a measuring system and sent to a kiln head burner, a kiln tail decomposing furnace or a pre-burning chamber of a cement kiln system for burning, and traditional fuel used in the process of cement production is replaced. Separated inert components participate in dosing of cement raw materials and enter the cement kiln system from a raw meal mill. The process achieves safe, harmless, recycling and energy-saving treatment and utilization of the municipal waste.

Description

technical field [0001] The invention relates to a method and a system for disposing of municipal garbage, in particular to a combined process of municipal garbage pretreatment and comprehensive utilization of cement kiln resources and a system thereof. It belongs to the cross technical field of cement production and municipal waste treatment technology. Background technique [0002] The treatment and utilization of municipal waste "harmless, reduced, and resourceful" is a worldwide issue. At present, the centralized treatment methods of urban and rural municipal waste in my country mainly include landfill, composting, and incineration. The landfill method occupies a large area and has a low degree of waste reduction. It requires anti-seepage treatment, and a biogas recovery and leachate treatment plant must be built, which is likely to pollute groundwater and surrounding air. The composting method is suitable for treating waste containing a lot of perishable organic matter...
