Problems solved by technology

However, waste incineration consumes a lot of fuel, and the treatment cost is expensive; and in order to prevent the pollution of flue gas generated by incineration, a set of flue gas treatment facilities is required
Usually the waste heat generated by waste incineration cannot be recovered
There are many types of incinerators for waste incineration, mainly grate incinerators, liquid jet incinerators, multi-stage incinerators, rotary kiln incinerators, fluidized bed incinerators and slag incinerators, etc., but none of them can achieve harmless The purpose of chemically treating HW11 and HW08 hazardous waste

Embodiment 1

[0027] A method for disposing of industrial hazardous waste HW11 and HW08 hazardous waste, which classifies HW11 and HW08 hazardous waste into solid hazardous waste, viscous hazardous waste and liquid hazardous waste. The solid hazardous waste The waste disposal steps are as follows: crush the solid hazardous waste and send it to the solid melting tank, add the extractant to the solid melting tank, heat it to 200°C through heat conduction oil, stir for 10 minutes, and discharge it to the centrifuge after being buffered by the centrifugal buffer tank A. The solid hazardous waste extract is separated into solid hazardous waste filtrate and solid hazardous waste filter residue. The solid hazardous waste filtrate enters the mixture tank through the raw material tank, and the solid hazardous waste filter residue enters the pyrolysis reactor.

[0028] The disposal steps of the viscous hazardous waste are as follows: put the viscous hazardous waste into the viscous melting tank, add t...

Embodiment 2

[0037] A method for disposing of industrial hazardous waste HW11 and HW08 hazardous waste, which classifies HW11 and HW08 hazardous waste into solid hazardous waste, viscous hazardous waste and liquid hazardous waste. The solid hazardous waste The waste disposal steps are as follows: crush the solid hazardous waste and send it to the solid melting tank, add the extractant to the solid melting tank, heat it to 180°C with heat conduction oil, stir for 18 minutes, and discharge it to the centrifuge after being buffered by the centrifugal buffer tank A. The solid hazardous waste extract is separated into solid hazardous waste filtrate and solid hazardous waste filter residue. The solid hazardous waste filtrate enters the mixture tank through the raw material tank, and the solid hazardous waste filter residue enters the pyrolysis reactor.

Embodiment 3

[0047] A method for disposing of industrial hazardous waste HW11 and HW08 hazardous waste, which classifies HW11 and HW08 hazardous waste into solid hazardous waste, viscous hazardous waste and liquid hazardous waste. The solid hazardous waste The waste disposal steps are as follows: crush the solid hazardous waste and send it to the solid melting tank, add the extractant to the solid melting tank, heat it to 150°C with heat conduction oil, stir for 30 minutes, and discharge it to the centrifuge after being buffered by the centrifugal buffer tank A. The solid hazardous waste extract is separated into solid hazardous waste filtrate and solid hazardous waste filter residue. The solid hazardous waste filtrate enters the mixture tank through the raw material tank, and the solid hazardous waste filter residue enters the pyrolysis reactor.

Abstract

The invention belongs to the technical field of industrial hazardous waste treatment, particularly relates to an industrial HW11 and HW08 hazardous waste treatment method and aims to provide a treatment method for pyrolyzing HW11 and HW08 hazardous wastes by indirect heating. The technical scheme includes that the HW11 and HW08 hazardous wastes are classified into solid hazardous wastes, viscous hazardous wastes and liquid hazardous wastes, the solid hazardous wastes and the viscous hazardous wastes are added into a melting kettle, extraction agents are added into the melting kettle, indirectheating extraction is performed, the wastes are centrifugally separated to obtain filtrate and filter residues, the solid hazardous wastes, the viscous hazardous wastes and the liquid hazardous wastesare mixed to obtain mixed materials, the mixed materials are dewatered and distilled to obtain light base oil, medium base oil, heavy base oil and maltha, and the solid hazardous waste filter residues and the viscous hazardous waste filter residues are pyrolyzed to obtain pulverized coal.

Description

technical field [0001] The invention belongs to the technical field of industrial hazardous waste treatment, and in particular relates to a treatment method for industrial hazardous waste HW11 and HW08 hazardous waste. Background technique [0002] The "National Hazardous Waste List (2016)" came into effect on August 1, 2016, among which various tar residues produced in the coking process and coal tar residues produced in the gas production and supply industry are clearly defined as HW11 hazardous wastes ; Oil sludge and oil feet from the process of oil exploration and refining, as well as waste oil residues from the oil processing industry, etc. are classified as HW08 hazardous wastes, which are toxic and flammable. Some small workshops simply dispose of hazardous waste for profit. This not only has potential safety hazards but also is not conducive to the long-term development of the industry. [0003] The current disposal method for hazardous waste is incineration or co...
