Garbage disposal system used in cement dry kiln production and disposal method thereof

Abstract

The invention discloses a garbage disposal system used in cement dry kiln production, comprising a garbage storage silo, a garbage crusher, a garbage supplying device and a decomposing furnace in dry cement production, and a rotary cement kiln for cement dry production, wherein the garbage disposal system is provided with a garbage gasification burner, the garbage supplying device is communicatedwith the garbage inlet of the garbage gasification burner, an air exhaust port of the garbage gasification burner is communicated with the decomposing furnace through a pipeline, and the material outlet of the decomposing furnace is communicated with the material inlet of the cement kiln. Through the technical proposal, the invention realizes long detention time of the gas generated by garbage burning in the kiln, completes combustion process, high disposal temperature and completes burning under the high temperature; the invention completely avoids the odor generation during the garbage burning process and especially the dioxin generation, reducing the pollution to the environment, and fully utilizes the energy generated by the garbage burning; compared with prior art, the invention has the advantages of less investment, and good economic benefit and social benefit.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to cement production technology and garbage treatment technology. More specifically, the invention relates to a garbage treatment system used in cement dry process kiln production. In addition, the present invention also relates to the processing method adopted by the processing system. Background technique [0002] At present, the main treatment methods of domestic waste include landfill, composting, heat treatment, classified recycling, and comprehensive utilization (RDF technology). The focus of current foreign research and application is sorting and recycling, sorting and recycling the collected household waste and comprehensively utilizing them, so as to reduce the waste of resources caused by traditional treatment methods. According to the process used, the heat treatment method is divided into: incineration method, pyrolysis method and gasification method. At ...

AI Technical Summary

Problems solved by technology

[0008] 1. Only the combustible part of the garbage can be used as alternative fuel, and the non-combustible part cannot be disposed of;

[0009] 2. A complex garbage pre-processing device is required. The garbage has to be crushed and sorted many times, and the sorting equipment needs to be imported from abroad;

[0010] 3. The sorted products (alternative fuels) still have a certain smell, and their storage and transportation will cause odor pollution to the surrounding air
