Abstract

The invention relates to environment-friendly smoke denitrification and desulfurization equipment which comprises an oxidizing chamber, a nitrogen removal chamber, a sewage treatment chamber, a desulfurization chamber and a bag-type dust collector. Due to the respective arrangement of the nitrogen removal chamber and the desulfurization chamber, the efficiency of removing nitric oxides and sulfuroxides in smoke is improved, residual water vapor in the nitrogen removal chamber serves as a raw material in the desulfurization chamber to use, heat is recycled, the heat is also recovered while performing smoke purification, and environment-friendly smoke treatment is really realized.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to the field of desulfurization and denitrification treatment of industrial fumes, in particular to environmental protection equipment for denitrification and desulfurization of fumes. Background technique [0002] Sulfur oxides and nitrogen oxides are currently the most important sources of air pollution. As the main energy source at present, coal is still widely used in industry, and it is difficult to change in a short period of time. It is widely used in traditional steel, cement, construction and coal-fired industries. After burning coal, it will produce sulfur oxides, Nitrogen oxides and other heavy metals are the main source of air pollution. Researchers mainly focus on how to purify coal-fired flue gas before or during emission, and remove harmful sulfur oxides, nitrogen oxides, and other heavy metal elements. At present, catalytic reduction denitrificat...
