Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization towers, in particular to a waste smoke desulfurization tower which is relatively safe to maintain. Background Art

[0002] The desulfurization tower is a tower-type equipment for desulfurization of industrial waste smoke and waste gas. It uses a nozzle to spray a water film downward. When the polluted smoke passes through the water film, the alkaline reagent in the water film can react with the sulfur dioxide in the gas to convert it into calcium sulfate, and at the same time adsorb particulate matter and harmful gases on the surface, thereby achieving the purpose of desulfurization and dust removal;

[0003] At present, the desulfurization tower also involves the recycling of water. Water can not only capture pollutants but also can be recycled. The desulfurization tower is equipped with a pumping and filtering mechanism. The used water is filtered and extracted through the pumping and filtering mechanism, and then sent to the nozzle again for the formation of water film, thereby achieving the purpose of water saving.

[0004] At present, the nozzles of the waste smoke desulfurization tower that spray liquid will be blocked due to impurities remaining in the filtered water after being connected to the filtered water for a long time. At this time, personnel are required to wear protective clothing and climb into the tower to clean, maintain and replace the nozzles. Since there are many pungent and harmful gases remaining in the tower, this method of climbing into the tower for long-term treatment is obviously not safe and convenient enough.

[0005] Based on this, the utility model designs a waste smoke desulfurization tower which is safer to maintain to solve the above problems. Summary of the invention
