Screen defroth device, also known as screen defroth device, mesh foaming device, defroth device. It is mainly used to separate droplets with diameters larger than 3μm ~ 5μm. When the gas with the mist foam rises at a certain speed, through the filter screen in the middle of the grid, due to the inertia of the rise of the mist foam, the foam and the filament collision and adhesion on the surface of the filament. Foam on the surface of the filament further diffuses and the gravity of the Foam itself settles, causing the Foam to form larger droplets to flow along the filament to its interleaved place. Due to the wettability of the filaments, the surface tension of the liquid and the capillary action of the filaments, the droplet becomes larger and larger until its own gravity exceeds the resultant buoyancy of the gas rising and the surface tension of the liquid, and it is separated and dropped. As long as the operation of gas speed and other conditions are selected properly, the gas through the screen defoaming device, its defoaming efficiency can reach more than 99%, can achieve the purpose of completely removing fog foam.

● Screen defoaming appliance has large specific surface area, light weight and large voidage

● Simple structure and easy to install and use

● It has the characteristics of high defoaming efficiency and small pressure drop, which is beneficial to improve the production efficiency of the equipment

● Large contact surface area, high defoaming efficiency
