Garbage incinerating exhaust gas using environment-friendly and energy-saving device

Abstract

A garbage incinerating exhaust gas using environment-friendly and energy-saving device comprises a garbage storage silo, a garbage breaker, a garbage feeder, a garbage incinerator, a decomposing furnace, a rotary cement kiln and a dioxin detector. The decomposing furnace, the rotary cement kiln and the dioxin detector are used for cement dry method production. The garbage feeder is communicated with a garbage inlet of the garbage incinerator. An exhaust port of the garbage incinerator is communicated with the decomposing furnace through pipelines. A material outlet of the decomposing furnace is communicated with a feeding port of the rotary cement kiln. The garbage incinerator and the rotary cement kiln are combined, high-temperature gas generated by garbage incineration is sent to the decomposing furnace and the rotary cement kiln, heat is provided for the decomposing furnace, meanwhile standing time of the self exhaust gas under a high-temperature condition in the decomposing furnace is over 4 seconds, combustion process is sufficient, incineration under the high-temperature condition is complete, and particularly the dioxin is prevented from being generated, and therefore pollution to environment is reduced, recycling of resources and sustainable development of economy are beneficial for being achieved, and an energy-saving and environment-friendly aim is achieved.

Description

technical field [0001] The invention belongs to the field of energy saving and environmental protection, and relates to waste treatment technology and cement production technology, especially to reduce and contain dioxins produced in waste incineration. Background technique [0002] At present, my country's domestic waste treatment methods mainly include sanitary landfill, composting and incineration. The landfill method has the disadvantages of occupying and consuming a large amount of land resources, leachate pollution, and landfill gas polluting the atmosphere. The composting method has disadvantages such as low sorting efficiency, waste biodegradable organic matter content must be greater than 40%, and poor fertilizer quality. [0003] Incineration, as an effective means of reducing volume and volume of waste disposal, has been increasingly widely used. Incineration treatment is to put garbage in an incinerator for burning, releasing heat energy, and the waste heat reco...

AI Technical Summary

Problems solved by technology

[0006] Due to the high investment cost and high operating cost of the current waste incineration method, and the traditional dioxin detection and treatment technology is high and the investment is relatively large, so the current factory uses RDF technology to process domestic waste. There is almost no separate dioxin detection and treatment control device
