Abstract

The present invention relates to tail gas treating process and apparatus, and is especially process and apparatus for treating high temperature fume containing acid gas, heavy metal, dioxin and other toxic gas from incinerating solid waste. The treating process includes the first reaction of the high temperature fume with deacidifying agent, active carbon and atomized water to eliminate toxic gases, and the subsequent reaction in a bag-type dust remover with one emergency passage for reaching high waste gas treating effect. The apparatus for treating high temperature fume has simple structure, low cost, low running expense, and long service life.

Description

technical field [0001] The invention relates to a tail gas treatment method and device, especially for high-temperature treatment of toxic gases such as acid gases (HCL, SOX, HF, etc.), dioxins (PCDDS / PCDFS) and heavy metals (Hg, Pb) after incineration of solid waste. A solid waste incineration tail gas treatment method and device for flue gas treatment. Background technique [0002] With the acceleration of industrialization and urbanization in our country, solid waste has become the only source of growth and is increasing rapidly. The prominent problem of solid waste pollution has attracted more and more attention. The annual production of industrial solid waste in the country exceeds 580 million tons, and the accumulated accumulation reaches 6.48 billion tons, and the annual production of municipal solid waste reaches 150 million tons. Solid waste incineration treatment technology can effectively realize its reduction, harmlessness and resource utilization, and is becomi...
