Hazardous waste harmless incineration system with low energy consumption

Abstract

The invention discloses a hazardous waste harmless incineration system with low energy consumption. The system adopts a plurality of latest energy-saving combustion technologies and energy-saving consumption reduction measures, optimizes on the whole, and well solves the energy-saving consumption reduction problem of the hazardous waste harmless incineration system. A unique gasification inner container of a solid and liquid waste gasification incineration unit ensures that hazardous solid and liquid wastes are pyrolyzed and gasified under the low-temperature oxygen debt condition; and the novel heat accumulation incineration manner of a gas waste incineration unit ensures that pyrolysis gas and hazardous gas waste are cleaned thoroughly and incinerated for discharge within the controlling index of national standard. The special system structure uses the high temperature heat generated in cleaning and incineration for pyrolysis and gasification, thereby facilitating energy conservation; the system also can select an oxygen enrichment combustor equipped with oxygen enrichment combustion-supporting wind supply equipment, so as to effectively increase the incineration temperature and reduce the combustion-supporting air amount; a waste heat recovering unit further can provide hot wind combustion support for incineration; therefore, the measures can effectively reduce the auxiliary fuel consumption, lower the energy consumption, and reduce the cost for treating hazardous wastes, and further the popularization and the application of the system are facilitated.

Description

technical field [0001] The invention relates to a harmless incineration system for low-energy hazardous waste, which belongs to the field of environmental protection industry and waste incineration treatment technology. Background technique [0002] As we all know, solid waste such as municipal solid waste and urban sewage sludge will become environmentally harmful waste if it is not disposed of properly; there are also most of the waste produced in the production process of industrial enterprises, medical institutions, teaching and scientific research, and laboratory units. Waste solids, waste liquids and waste gases are also harmful to the environment. Improper disposal of these harmful wastes (referred to as "hazardous waste") will bring great harm to human beings and the living environment (surface water, groundwater and air). Big hazards must be dealt with properly. [0003] Incineration of hazardous waste is one of the most effective methods of harmless treatment, esp...

AI Technical Summary

Problems solved by technology

[0018] The fundamental purpose of incineration treatment of hazardous waste is to make it harmless (that is, no secondary pollution from harmful dust, slag and flue gas), but the energy consumption is too high and the treatment cost is too high, and neither the government nor enterprises can afford it!
