Environmental-protection and energy-saving garbage incineration and waste gas utilization device

Abstract

The invention relates to an environmental-protection and energy-saving garbage incineration and waste gas utilization device, which comprises a garbage storage silo, a garbage crusher, a garbage feed device, a garbage incinerator, a decomposing furnace, a rotary cement kiln and a Dioxin detector, wherein the decomposing furnace, the rotary cement kiln and the Dioxin detector are used for dry-process cement production; the garbage feed device is communicated with the garbage inlet of the garbage incinerator; the exhaust port of the garbage incinerator is communicated with the decomposing furnace through a pipeline; and the material outlet of the decomposing furnace is communicated with the feed port of the cement kiln. Garbage incineration and the rotary cement kiln are combined with each other, so that high-temperature gas generated by garbage incineration is delivered to the cement kiln and the decomposing furnace again, and when heat is provided for the decomposing furnace, the retention time of the waste gas generated by the garbage incineration reaches as long as 4 seconds or above under the high-temperature condition in the decomposing furnace; the combustion process is full; the incineration at high temperature is thorough; and especially, Dioxin is prevented from being generated, and the environmental pollution is reduced, thereby being beneficial to realize the resource recycling and the sustainable development of the economy, and achieving the goals of energy saving and environmental protection.

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, biodegradable organic matter content of garbage 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...

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
