specific Embodiment approach

[0062] 1. A non-combustible discharge system 6 is provided at the bottom of the garbage gasification furnace 5 according to the present invention.

[0063] The non-combustible discharge system 6 communicates with the ash outlet 17 .

[0064] The purpose of this program is to achieve the most thorough reduction in volume and quantity, and all the separated components can be recycled.

[0065] The use of cement burning system to treat municipal solid waste is the only one among various waste treatment methods that does not discharge waste residue and waste gas. In the production process of the cement industry, there are only raw materials and clinker produced by the calcination process, and there is no problem of slag incineration in general incinerators; and the entire system operates under negative pressure, and there is almost no leakage of smoke and dust. question.

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 communicated with 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 ...
