Hazardous waste incineration process and system

Abstract

The invention discloses a hazardous waste incineration process and system. The hazardous waste incineration process comprises the following steps that S1, compatibility is conducted, specifically, hazardous waste is mixed and compatible and conveyed into a first incineration area; S2, incineration is conducted, specifically, the mixed materials obtained after compatibility are subjected to a primary combustion reaction in a first incineration area, and primary flue gas is obtained; the primary flue gas is conveyed into a second incineration area to be subjected to a secondary combustion reaction, and secondary flue gas is obtained; S3, flue gas treatment is carried out, specifically, the secondary flue gas is cooled and purified and then discharged; in the primary combustion reaction process, used combustion-supporting gas I contains 45%-55% of oxygen; and in the secondary combustion reaction process, used combustion-supporting gas II contains 75-85% of oxygen. According to the processand system, the investment and operation cost is low, and the treatment effect is good.

Description

technical field

[0001] The invention relates to the technical field of environmental protection technology, in particular to a hazardous waste incineration technology and system. Background technique

[0002] With the rapid development of the economy, modern industrialized industries such as petrochemical, electronic processing, fine chemical, pharmaceutical and chemical industries, and basic chemical raw material manufacturing are all developing rapidly. These industries will produce a large amount of organic or inorganic waste in the manufacturing process. Most of these wastes are hazardous wastes with characteristics of toxicity, corrosion, infectivity, flammability, reactivity and even infectivity. If not handled properly, they will usually cause serious harm to human health or the environment.

[0003] Hazardous waste treatment must follow the principles of "reduction, harmlessness, and recycling". Commonly used hazardous waste treatment methods include incineration, la...

Examples

Embodiment Construction

[0047] In order to describe the technical content, achieved goals and effects of the present invention in detail, the following descriptions will be made in conjunction with the embodiments and accompanying drawings. The test methods used in the examples are conventional methods unless otherwise specified; the used materials, reagents, etc., are commercially available reagents and materials unless otherwise specified.

[0048] An embodiment of the present invention is: a hazardous waste oxygen-enriched incineration system, including a feed system, an incineration system (that is, a closely connected rotary kiln and a secondary combustion chamber) and an exhaust gas treatment system, and the feed system is used to transport the waste into the kiln It enters the incineration system, is incinerated by the incineration system, and then is purified by the tail gas treatment system before being discharged. Such as figure 1 As shown, the incineration system includes a closely connec...
