Electronic Waste Recycled Exhaust Processor

Abstract

The invention discloses a regenerated tail gas processor for electronic waste, which comprises a semi-dry adsorption tower, a lime slurry preparation system, an activated carbon injection system, a lime slurry preparation system, and the activated carbon injection system communicates with the semi-dry adsorption tower; it also includes a dust collector, Suction mechanism. The invention has simple structure and good impurity removal effect.

Description

technical field

[0001] The invention relates to the technical field of waste gas treatment, in particular to a regenerated tail gas processor for electronic waste. Background technique

[0002] The flue gas produced by electronic waste incineration mainly includes: 1. Acid gases (HCl, HF, SOx, etc.), dust (particulate matter), heavy metals (Hg, Pb, Cr, etc.) and highly toxic organic pollutants (dioxins, furans, etc.) etc.); HCl and HF are mainly produced during the incineration process of chlorine-containing plastics, resins and other organic matter in garbage; SOx is mainly produced during the incineration process of sulfur compounds contained in garbage, of which SO 2 Mainly, under the catalysis of heavy metals, a small amount of SO will be generated 3 . 2. The dust is mainly composed of inorganic components in the incineration products, with a particle size range of ≤200μm, usually at the outlet of the waste heat boiler. 3. Heavy metals include Hg, Cd, Pb, As, etc., wh...
