Industrial dangerous waste incineration processing system for realizing multiple physical states

Abstract

A system for implementing multiple-physical state industry dangerous waste incineration and disposal relates to the garbage disposal technology of the environment protection technical field. Two seal doors are arranged at a bulk waste material feed port or a barreled waste material feed port on a rotary kiln feed hopper. The rotary kiln and a second combustion chamber frame all adopt carbon steelmaterials, refractory materials a working layer of the rotary kiln select chromium fused alumina abrasion-proof plastic materials, refractory materials of the second combustion chamber select abrasion-proof pouring materials. The rotary kiln is provided with a primary fan and a combustion-supporting combustor 1 which are connected with the rotary kiln, the second combustion chamber is provided with a second fan and a combustion-supporting combustor 2 which are connected with the second combustion chamber, a stuffing absorbing tower and a flue gas heater are connected in turn between the bag-type dust remover and a draught fan. Compared to the prior art, the invention can effectively destroy large quantities of toxic and noxious high molecule organic matters, can effectively avoid phenomenon of the collapse fall of the rotary kiln incineration furnace wall and the burning ring of the steel body, and can avoid high-temperature corrosion and low-temperature corrosion, the invention has advantages of good operation economical performance, fluent slag system and low pollution discharge index.

Description

technical field [0001] The invention relates to a garbage treatment technology in the field of environmental protection technology, and is particularly suitable for a rotary kiln incineration treatment system for solid, semi-solid and liquid industrial hazardous waste. Background technique [0002] Hazardous waste not only has the potential and long-term nature of general solid waste to pollute the environment, but also has hazards such as flammable, explosive, toxic, harmful, corrosive, and contagious, and the harmful consequences are cumulative, lagging, and long-term. A variety of thermal treatment technologies are available for hazardous waste disposal, but the most commonly used method so far is high-temperature incineration. [0003] Our country chooses the rotary kiln incinerator as one of the main furnace types for hazardous waste incineration, especially suitable for the incineration system of commercial centralized treatment plants. The rotary kiln incinerator has...

Problems solved by technology

[0006] c) Industrial hazardous waste usually contains a variety of chlorine-containing high-molecular organic substances. Incineration causes chlorine to be released along with the flue gas, which is likely to cause high-temperature and low-temperature corrosion of the flue and heat exchange surfaces

For example, the Chinese patent application number is 200610154696.9 "Hazardous Waste Garbage Rotary Kiln Incineration Equipment System", although the flue gas purification technology has been proposed, but the equipment system is complicated, including three-stage packing towers, which will inevitably cause large flue gas resistance and water consumption. shortcoming

[0007] d) The incineration process of chlorine-containing waste is also prone to produce dioxins, which are extremely harmful and have a small content in the flue gas, so perfect control technology is required

For example, the Chinese Patent Application No. 200610154696.9 is "Dangerous Waste Garbage Rotary Kiln Incineration Equipment System". Large, it is easy to cause the operation failure of the follow-up dust removal equipment
