A new screen demister with adjustable foam area in addition to the ability to do, can be the size of the volume of operations, the amount of acid mesh product number is automatically adjusted according demister area, and always maintain a high efficiency demister, while avoiding liquid Pan occurred. 1: Overview screen demister because of its excellent properties have been widely used at home and abroad sulfuric acid plant, with the development of the practical application of the accumulation of experience and technology, in addition to a number of shortcomings screen demister is also increasingly apparent, for example, in addition to its Mo limited range, ability to adapt to changes in operating conditions of the gas is weak and so on. To solve these problems, many large foreign companies developed a modified polypropylene screen demister demister improved mainly reflected in the way to choose the ideal mesh material, woven wire mesh and bedding improved method not only improves the demister of efficiency, but also expanded the scope of demister, while increasing the drainage of the screen, and enhance the ability of anti-flooding. Screen demister has an obvious advantage in preventing clogging, easy to maintain pressure drop laugh, etc., once in a particular environment, not instead. Currently, the drying tower acid plant is still commonly used in wire mesh demister, domestic construction of a large smelter in the drying tower acid plant is also a choice of screen demister. The problem is the efficiency of wire mesh demister is reliable. Under construction in the large smelter and hyaluronic acid plant, as happened flash smelting process smelting process used, the amount of smoke generated great volatility for the sulfuric acid, if the design and construction of the drying tower and reach technology quality requirements, or conditions do not meet the operational requirements of the production process, after production, etc., may cause excessive gas entrained acid foam demister production, will lead to adverse consequences. Screen demister wire mesh demister works in the usual chemical operations encountered gas dispersed droplets of a diameter of about 0.1 ~ 5000μm. General particle size 100μm particles due to the sedimentation rate faster than demister price, its separation problem is easily solved. Usually larger than the droplet diameter 50μm, the separation can be used gravity sedimentation; 5μm droplets above available inertial impaction and centrifugal separation; for smaller fine mist will have to try to make it together to form larger particles or fibers demister and electrostatic demister. Screen demister (also known as mist eliminators, mist catcher), which is mainly used for the separation diameter greater than 3μm ~ 5μm droplets, works as shown on the right. When the gas with a liquid foam to rise at a constant speed, frame by wire mesh on the grid, since the liquid foam rise of inertia, so that the filaments collide with the liquid foam adhered to the surface of the filament. Liquid foam on the filament surface and the liquid foam itself further spread of gravity settling, the liquid foam to form larger droplets flow along the filament to its interleaving. Since the filaments of wettable, capillary action and surface tension of the liquid filaments, such that the droplets increases, until it exceeds the force of its own gravity and the buoyancy of gas rises when the liquid surface tension, it was separated and fall, flow downstream equipment to container. As long as gas velocity and other conditions selected when, after the gas through the screen in addition to Mo, the demister efficiency can reach more than 97%, can achieve the purpose of removing the mist.
