Abstract
The invention relates to a solar energy film apparatus for evaporative concentration of waste water. Simple and practical normal-pressure technology using solar energy for evaporation is adopted in the apparatus and enables the salt content of waste water high in salt content to be reduced to 10% through concentration. The distilled water is reused, and the concentrated liquid can directly enter a crystallization apparatus, so that zero discharge of waste water is realized. Compared with a conventional hot method and reverse osmosis technology, the apparatus is energy saving and eco-friendly, and is effectively reduced in initial investment cost and operation cost of systems. The apparatus is composed of a waste water tank, a solar energy film evaporator, a fresh-water tank, a concentrated water tank, and a concentrated water circulation pump. The waste water high in salt content forms a uniformly-dispersed water film through a flow distributor; water vapor evaporated by heating rises to the inner surface of the film through the solar energy film evaporator and aggregates to droplets; the droplets flows to a fresh-water collecting tank along the inner surface of the film; and fresh water can be recycled and reused. Waste water is continuously subjected to evaporative concentration and is collected in the concentrated water tank through a concentrated water collecting pipe. The concentrated water can be continuously recycled and repeatedly subjected to evaporative concentration according to concentration requirements.
