Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization powder conveying, in particular to a new desulfurization powder conveying device. Background Art

[0002] In many factories in my country, desulfurization is generally carried out by limestone gypsum desulfurization, which is applied to desulfurization towers. The desulfurizer used in desulfurization towers is limestone desulfurizer, which is used in large quantities. When processing limestone desulfurizer, most of them first grind limestone into stone powder, and then manually put the lime powder into the feed hopper of the screw conveyor according to the proportion, and then the screw conveyor that transports from bottom to top is transported to a relatively large mixer, and the water and stone powder are mixed into desulfurization slurry by the stirring mixer;

[0003] The desulfurization slurry is then sprayed into the desulfurization tower using a circulating slurry pump, pouring down from top to bottom. The stone powder reacts chemically with the sulfur dioxide in the flue gas to generate calcium sulfite, which then reacts with oxygen to generate calcium sulfate, thereby removing the sulfur dioxide in the flue gas.

[0004] At present, when lime powder is poured into the screw conveyor manually according to proportion, some of the lime powder is easy to float out from the feed hopper of the screw conveyor, causing pollution to the environment and easy to be inhaled in large quantities by people, causing physical harm.

[0005] Based on this, the utility model designs a new desulfurization powder conveying device to solve the above problems. Summary of the invention
