Description

TECHNICAL FIELD

[0001] The utility model relates to flue gas purification technical field more specifically, the utility model relates to a kind of spraying device for flue gas purification. BACKGROUND

[0002] Flue gas is a gas mixture produced during combustion, usually containing particulate matter, harmful gases and water vapor, etc. These components can pollute the environment and harm human health. In order to reduce these negative effects, flue gas purification is necessary. The flue gas purification spray tower is a commonly used purification equipment, mainly used for removing particulate matter and harmful gases in flue gas.

[0003] When flue gas enters the spray tower, it will come into contact with the liquid sprayed inside the tower. The liquid forms fine droplets through the nozzle, increasing the contact area with the flue gas. In this process, the particulate matter in the flue gas is captured by the droplets and settles to the bottom with the liquid, while the harmful gases may dissolve in the liquid or react with the chemicals in the liquid, thereby being removed.

[0004] However, in actual application, the flue gas has a certain flow rate when entering the interior of the spray tower. Through this flow rate, the flue gas will scour the inner wall of the spray tower, making the flue gas more concentrated and unevenly distributed. When the flue gas rises along the inner wall of the spray tower, although the spray head of the spray tower is usually provided with multiple groups to ensure full coverage, the spray angle of a single nozzle of the spray tower is usually not more than 120°, and the droplets form a "conical coverage area" when falling due to gravity. Near the tower wall, the coverage rate of the overlapping area of adjacent spray cones is insufficient (usually <70%), while the central area is excessively covered due to the superposition of multiple spray heads (coverage rate >150%), resulting in insufficient liquid volume for edge purification and further uneven and incomplete flue gas purification. Therefore, it needs to be improved and optimized. SUMMARY
