Types of Air Wahser Points : types of air wahser, unitary spray washer, central station washer There are two types of’ air washer
1. Unitary spray washer
2. Central station washer 1. Cemtral Station Washer The most commonly applied type of washer equipment is the central station washer. This washer consists of-a rectangular steel chamber, closed at the top and sides and mounted on a shallow watertight tank of steel .or concrete. Inlet baffles located at the alt-entering end of the washer promote uniform air velocities through the washer and minimize the spraying back of water into the entrance chamber as a result of air eddy currents. At the air-leaving end of the washer, eliminators are provided to remove entrained water droplets. Within the washer spray chamber two banks of opposing spray nozzles provided finely divided droplets of water uniformly distributed. After contacting the air, the water is collected to the sprays by a re-circulating pump. A central station washer may be designed for use as a humidifier or as a dehumidifier. The physical arrangement is the same in either case. A dehumidifier is normally shorter in air way length than a humidifier. 2. Unitary Spray Washer Washers may also be obtained in a unitary design. A unitary spray washer, comparable in design and function to a central station washer, other .types of unitary washer involve the wetting of a fibrous fill or set of’ pads located in the air stream.
