Description

Technical Field

[0001] The utility model relates to a desulfurization slurry spraying device of a wet desulfurization tower, belonging to the technical field of flue gas desulfurization. Background Art

[0002] Industrial production often produces a large amount of flue gas, such as power generation, smelting, heating, etc. The flue gas carries a large number of harmful substances, among which SO2 is one of the main components. If it is not treated and directly discharged into the atmosphere, it will not only form acid rain and damage the environment, but also cause a variety of respiratory diseases. In recent years, with the continuous strengthening of environmental governance calls, the state has put forward increasingly stringent emission standards for the SO2 content in industrial flue gas.

[0003] The desulfurization tower is a commonly used flue gas desulfurization equipment. The existing desulfurization tower usually has a spray layer set in the upper part of the desulfurization tower, spraying the desulfurization slurry downward, and the flue gas is introduced from the lower side of the desulfurization tower, and rises in the desulfurization tower to react with the sprayed desulfurization slurry. In this desulfurization method, since the contact time between the flue gas and the desulfurization slurry is short, it is usually necessary to set up multiple spray layers to desulfurize the flue gas multiple times, so that the height of the desulfurization tower is increased. In addition, most of the existing spray layers are staggered up and down, and most of the spray layers are composed of multiple arranged spray pipes, but the spray pipes of multiple spray layers are staggered, so that there are gaps between the spray pipes arranged up and down. When the flue gas is discharged through the gap, it cannot be processed by the desulfurization slurry, which affects the desulfurization efficiency.

[0004] In summary, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention
