Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of desulfurization towers, and in particular relates to a desulfurization tower with a self-cleaning function. Background Art
[0002] The desulfurization tower is mainly composed of a wire mesh demister, a spray nozzle array and a slurry pool. When working, the flue gas enters the desulfurization tower through the main pipeline. Below the desulfurization tower is a slurry pool. The slurry in the pool is a mixture of limestone and water. When the flue gas enters the desulfurization tower, the slurry will be transported to the spray nozzle array above along the pipeline to spray the flue gas. The sprayed limestone slurry will absorb sulfur dioxide in the flue gas to achieve the purpose of flue gas desulfurization. The wire mesh demister at the top is to remove the water vapor generated by the limestone slurry heated by the high-temperature flue gas to meet environmental protection requirements, but Acid foam is often entrained in the flue gas and remains on the wire mesh demister. When the equipment is out of service for a long time, air enters the tower and the moisture it carries reacts with the acid foam retained in the wire mesh demister to form dilute acid. The dilute acid is highly corrosive to the metal wire mesh, so the wire mesh demister needs to be cleaned regularly to avoid equipment damage. The prior art is to remove the wire mesh demister from the desulfurization tower for cleaning, and then reinstall it into the desulfurization tower after natural air drying. However, loading and unloading the wire mesh demister is relatively laborious, and the natural air drying takes a long time, which affects the use of the desulfurization tower. Utility Model Content
