AI Technical Summary
Technical Problem
Existing demisters have poor demisting effect, and the mist is easily remixed with water droplets, resulting in increased water content, equipment corrosion, and environmental pollution.
Method used
The system employs vertically and horizontally installed defogging components to separate the fog through inertia and collision. Combined with a hydrophilic semi-permeable membrane and a secondary defogging process, it separates water droplets from the fog and collects them back to prevent remixing.
Benefits of technology
It significantly improves the defogging effect, prevents the fog from having high water content, reduces equipment corrosion, and lowers the risk of environmental pollution.

Abstract
The utility model belongs to the technical field of waste treatment, and discloses a demisting device for an absorption tower, the demisting device comprises a demisting assembly I and a demisting assembly II, the demisting assembly I is coaxially mounted in an air inducing pipeline, a backflow cavity I is positioned between the side wall of a reaction cavity and the inner side wall of the absorption tower, the top end of the backflow cavity I is open, and the air inducing pipeline is communicated with the backflow cavity I; a second backflow cavity is formed between the outer side wall of the air inducing pipeline and the outer cavity wall of the top end of the reaction cavity, the second backflow cavity is communicated with the air inducing pipeline, a hydrophilic semi-permeable membrane is arranged at the communication position, and the side end of the second backflow cavity is communicated with the first backflow cavity; the bottom of the exhaust cavity communicates with an air inlet pipeline, and the lower end of the air inlet pipeline communicates with the air inducing pipeline and the first backflow cavity. The second demisting assembly is installed in the air inlet pipeline, and an exhaust port communicating with the outside is formed in the top of the exhaust cavity. According to the demisting device, the flowing path of liquid is changed, the situation that the liquid and gas are repeatedly mixed to generate mist again can be reduced, secondary demisting is conducted through the second demisting assembly, and the demisting effect is improved.
