Description

Technical Field

[0001] The present application relates to the technical field of waste gas treatment spraying, and in particular to a spray purification device for waste gas treatment. Background Art

[0002] Waste gas refers to toxic and harmful gases discharged by humans in the process of production and life, especially waste gas from chemical plants, steel plants, pharmaceutical plants, etc. In order to reduce the pollution to the environment during the waste gas emission process, the waste gas needs to be purified. The common method is to neutralize the waste gas by spraying before discharging it;

[0003] The spray purification device used in the prior art solution usually uses a nozzle in a stationary state. During the spraying process of the nozzle in the stationary state, the spray liquid cannot be evenly distributed in the exhaust gas, which will lead to insufficient gas-liquid contact, thereby reducing the absorption efficiency of pollutants. Although the prior art solution can use multiple nozzles to perform uniform spraying, the nozzles are easily clogged by sediments. If the number of nozzles is large, the maintenance cost and downtime will increase.

[0004] In view of this, we propose a spray purification device for waste gas treatment. Utility Model Content

The rotating spray nozzle disperses the spray liquid into fine droplets through centrifugal force, thereby effectively increasing the surface area of ​​gas-liquid contact and improving the absorption efficiency, so that the pollutants in the exhaust gas can contact and react with the spray liquid more effectively. In addition, since the droplets generated by the rotating nozzle are small and evenly distributed, the deposition of the spray liquid in the nozzle is reduced, thereby reducing the risk of blockage, and there is no need to use multiple nozzles, which also reduces the maintenance cost;
