High-efficiency smog demister for demisting and collecting water and preparation method thereof

Abstract

The invention discloses a high-efficiency smog demister for demisting and collecting water and a preparation method thereof and belongs to the field of smog demister preparation. The preparation method comprises the following steps that (1), a demister is put into absolute ethyl alcohol to be washed and dried for standby application; (2), after the demister is dried, the demister is immersed by aPP treating agent and then is dried; (3), organic resin and hydrophobic gas phase silicon dioxide fine powder are dispersed into organic solvent and a bonding layer is obtained; (4), acid chain form waterborne silica sol is dispersed into an alkaline aqueous solution, tetraethyl orthosilicate and a hydrophobic treating agent are added into the alkaline aqueous solution, then micron-sized particlesare added into the alkaline aqueous solution and an inhomogeneous wet coating is obtained; and (5), after the demister obtained in the step (3) is semi-solidified, the demister is impregnated and lifted and pulled in the hybrid super-hydrophobic coating prepared in the step (4), and then is dried. The smog demister has better condensation and moisture condensation enhancement, high-efficiency water collecting and demisting effects as well as good durability, and is low in cost and easy to apply on a large scale. The smog demister has wide application prospects in the fields of fast demisting, water collecting, heat transfer and the like.

Description

technical field [0001] The invention belongs to the technical field of smoke eliminator preparation, and in particular relates to a high-efficiency mist eliminator for water collection and a preparation method thereof. Background technique [0002] Due to the rapid growth of the world's population, the sharp increase of industrial water consumption and the aggravation of environmental pollution, the shortage of clean water resources has seriously affected the basic survival of human beings, and has aroused widespread concern around the world. At present, steam as an energy source is widely used in the fields of water purification and seawater desalination, such as thermal power plants, large-scale seawater desalination systems, desert water collection, solar distillation and other systems. The demister is an important device for saving water and protecting the environment in a large number of steam system equipment. It is installed above the water spray pan. When the risin...
