Description

Technical Field

[0002] In the current field of flue gas purification for domestic waste incineration, semi-dry reaction towers are commonly used as deacidification equipment. The flue gas of the semi-dry reaction tower enters the cylinder tangentially, and the flue gas moves in a circular motion. At the same time, the lime slurry is atomized by the atomizer and mixed with the flue gas in reverse. The acid gas in the flue gas undergoes an acid-base neutralization reaction. The solid phase reaction products are easily adhered to the wall of the reaction tower under the action of centrifugal force, and accumulate thicker and thicker over time, which has a great impact on the reaction efficiency. If a large amount of accumulated ash suddenly falls off, it is also easy to generate a large impact load on the lower ash hopper, affecting the safe operation of the equipment.
