York 431,421,709 mesh demister pad for distillation column,drying tower

wire mesh demister used for gas separation tower entrained droplets, to ensure that the mass transfer efficiency, reduce the loss of valuable materials and improving the tower after the operation of the compressor, more commonly in the top screen defoaming device Settings. Can effectively remove 3 - 5um droplets, tray if setting between demister, not only can ensure the mass transfer efficiency of tray, also can reduce the plate spacing. So the screen defoaming machine is mainly used for gas liquid separation. Also for the air filter used for gas separation. In addition, the screen also can be used as instrument of buffer in instrument industry, in order to prevent the radio interference of electromagnetic shielding, etc.

Type of wire mesh demister

The efficiency of the pad is a function of pad thickness, wire diameter, closeness of weave, etc. The thickness of the pad is not very critical since droplet coalescence is completed in the first one or two inches and the extra thickness is mainly for catching the re-entrained material. Thickness usually provided is between 100 mm and 300 mm.

A vane type demister consists of a number of parallel corrugated plates. When gas passes between the plates it has to change direction a number of times. The heavier particles are thrown out and get collected in the pockets. Coalescence of small particles into bigger particles is provided by agitation and surface contact. The surface of the element is usually wet and particles striking it are absorbed into the liquid film. The efficiency of the vane type demister is a function of pressure drop since closer plates introduce more pressure drop.
