ABSTRACT:
The water evaporation apparatus functions to increase the concentration strength of a contaminant solution in wastewater, for more economical disposal. A blower conveys an air stream along an air-conduit, over a nozzle or atomizer. The atomizer converts the incoming dilutely-contaminated water into fine droplets, and injects and distributes the droplets into the airstream. An air-heater is located upstream of the atomizer, and heats the airstream to a temperature of 110° C. at the atomizer. A droplet-collector receives the airstream, and the droplets, and mechanically extracts the liquid droplets from the airstream. The airstream leaves the droplet-collector at 65° C. in a saturated condition. The droplets coalesce, and become the final-water, comprising the strongly concentrated contaminant solution. An exhaust-conduit conveys air that has passed through the droplet-collector to the air-outlet. A heat-exchanger transfers heat from the exhaust airstream into the intake airstream, to supplement the air-heater.
