Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization in the steel industry, in particular to a desulfurizer feeding device and a ground dust removal flue gas desulfurization device. Background Art

[0002] The flue gas generated by coke ovens and dry coke quenching devices during the production process contains sulfur dioxide. In order to meet the requirements of ultra-low emissions, a ground dust removal station desulfurization device is installed. The desulfurization principle is to spray the canned powdered (calcium hydroxide powder) desulfurizer into the flue gas pipeline through the pneumatic conveying system. After the desulfurizer contacts with SO2 in the flue gas and completes a reaction, it enters the bag filter with the flue gas. The incompletely reacted desulfurizer reacts with SO2 on the bag for a secondary reaction. In this way, the SO2 in the flue gas is fully reacted, and the flue gas after desulfurization and dust removal is pressurized by the induced draft fan and sent to the chimney for discharge. Because the desulfurizer is ultra-fine powder and has a certain water absorption, it is easy to block the material during operation, resulting in poor feeding of the desulfurizer, affecting the flue gas desulfurization effect, and making the flue gas emission fail to meet the standard.
