Embodiment Construction

[0167] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the invention, not to limit the invention.

[0168] This embodiment provides a high-temperature plasma melting process and system for treating hazardous waste fly ash and residue, such as figure 1 shown, including the following steps:

[0169] (a) Hazardous waste material pretreatment system

[0170] The fly ash (1) delivered by the external unit is put into the ash storage tank (2) for temporary storage, and then sent to the molding machine by a special conveying device (3) rolled into a ball or extruded into a block material, and then conveyed The machine is sent to the vibrating screen (4) for screening and separation, and the materials that meet the mo...

Abstract

The invention discloses a technical process and a treatment system for the melting treatment of the fly ash and residue of hazardous waste through high-temperature plasma. The treatment process comprises the following components: (a) a pre-treatment system for molding fly ash and crushing and screening of the hazardous waste residue and the waste glass; (b) a measuring, weighing, conveying and feeding system; (c) a high-temperature plasma melting treatment system; (d) a microwave plasma secondary combustion chamber; (e) a boiler and a gas-gas heat exchanger cooling and dust removal system; (f)a circulating fluidized bed and a desulfurization and deacidification and dioxin adsorbing device through a semi-drying method; (g) a desulfurization and deacidification and dioxin adsorbing device through a venturi drying method; (h) a ceramic fiber filter pipe dust remover and a dust removal, desulfurization and denitration and dioxin eliminating device; and (i) a smoke exhausting system. The process actually achieves a more thorough treatment effect for volume reduction, innocuity, and resource, the secondary environmental pollution problem can be avoided, the daily processing capacity ishigh, the economic operating cost is lower, and the working environment is safer and more environment-friendly.

Description

technical field [0001] The invention relates to the field of hazardous waste treatment, in particular to a high-temperature plasma melting process and system for treating fly ash and residue of hazardous waste. Background technique [0002] Hazardous waste refers to the hazardous waste that is included in the national list of hazardous waste or determined according to the identification method of hazardous waste stipulated by the state and has hazardous characteristics such as poisonous, explosive, flammable, corrosive, chemically reactive, infectious, radioactive, etc., and pollutes the environment. substance. The random discharge and unreasonable disposal of hazardous waste will endanger people's health, and the long-term accumulation will seriously damage the ecological environment. [0003] At present, in the domestic and foreign markets, high-temperature plasma technology is the best non-toxic solution for fly ash after incineration, crushed electronic waste, liquid or...
