Avirat FRP Moulders offers Cooling Tower FRP Air Washer. The Basic Sections of An Air Wsher: The basic components of an air washer system are a chamber that contain a series of spray nozzles, an eliminator section that removes water from the air that is exiting the air washer and a sump which catches both the sprayed water droplets and the water that was collected by the eliminators. The spray section will either add moisture to the air or dehumidify the air, while washing solid particles out of the air. The eliminator section in many cases is a "W" or a series of "W"s in shape. This section, forces the air to contact the eliminator components, which in turn knocks down water droplets and air borne solids. The sump is the collection basin for the system. The washed out solids, lint, dust, and water all collect in this area. Humidification By An Air Washer: Humidification is accomplished by using the recirculating spray water, washing preheated air with the spray water, and by heating the spray water. In general, the humidification of the air occurs as the humidity of the outside air decreases. This allows the water from the sprays to entrain in the low humidity air and increase the humidity of the washed air as it leaves the system for the plant. The heating of the spray water or the heating of the air prior to the air washer creates a condition that allows the air passing to the plant to hold a higher level of moisture. The amount of moisture that is required for the plant use will dictate the degree that the air or spray water will need to be heated.
Cleaning The Air With An Air Washer: Air is cleaned by an air washer when particulate matter impinges on the wetted surfaces of the eliminator blades. Air is also cleaned, when the sprayed water generates enough ionization to neutralize the charges on the particles in the service area so that they can be dropped out into the sump as they are drawn through the air washer. The cleaning of the air will remove lint, oils, and other airborne particles from the air. This builds up the level of the solids in the water which must be removed either from over flow or bleed. Chemical treatment can improve particle removal and prevent nozzle clogging from excessive solids build up.
