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, and also solves the technology problems of present solid waste burned fume treating system such as high investment and operating cost and low pollutant removal rate.

Description

Technical field [0001] The present invention relates to a tail gas treatment method and device, especially for high temperature containing acid gas (HCL, SOX, HF, etc.), dioxins (PCDDS / PCDFS) and heavy metals (Hg, Pb) and other toxic gases after solid waste incineration A solid waste incineration tail gas treatment method and device for flue gas treatment. Background technique [0002] With the acceleration of my country's industrialization and urbanization, solid waste has become the only energy source for growth, and it is increasing rapidly. The prominent solid waste pollution problem has attracted more and more attention. The annual amount of industrial solid waste generated in the country exceeds 580 million tons, and the cumulative amount of accumulated storage reaches 6.48 billion tons, and the annual output of municipal solid waste reaches 150 million tons. The solid waste incineration treatment technology can effectively realize its reduction, harmlessness and resource ...
