Description

Technical Field

[0001] The utility model relates to the field of industrial technology, in particular to a denitration tower cleaning device. Background Art

[0002] The desulfurization and denitration tower adopts nozzle-type empty tower spraying. Due to the atomization effect of the nozzles, the denitration agent is split into countless small-diameter liquid droplets, and its total surface area is expanded by thousands of times, enabling sufficient contact between the gas and the liquid. The larger the gas-liquid contact area, the higher the two-phase mass transfer reaction efficiency. However, long-term desulfurization will cause a scaling layer to adhere to the inner wall of the denitration tower. This scaling phenomenon has a huge impact on the operation of the denitration tower. Therefore, it is necessary to remove the scale in time to reduce the damage to the inner wall of the denitration tower, ensure the normal operation of the equipment and extend its service life.
