Description
Technical field
Utilize the capillary action principle to increase technology and equipment that the water surface of evaporation realization is carried out sea water desaltination with sun power thereby the invention belongs to.
Background technology
As everyone knows, tellurian water nearly all is stored in the ocean, and the Evaporation of dependence sun power is transformed into the gasiform cloud with seawater and is transported to land-based area, and the form with sleet drops to ground at last, becomes the surface water of rivers and lakes and permeates subterranean underground water.Because be subjected to the influence of various natural causes, tellurian Freshwater resources are distributed on the space-time all very uneven, lack of water and flood in different areas and the different time of areal all can take place.Especially coastland, Freshwater resources mostly very plaque are weary, how to implement sea water desaltination and be one of focus that people study for a long period of time.Evaporation is that people study one of maximum method for desalting seawater, the coastland abundant at heat resource has very big magnetism, particularly novel flash evaporation technology, used heat and low grade heat energy are in the comprehensive utilization of heat resource, can realize economic desalting process, generally can reach the water producing cost of surface water, if but use live steam then ambigendi locus economically, cost will be at 8-10 unit/ton water; Reverse osmosis technology is a lot of desalination technology of present industrial applications, and its water producing cost is minimum can to reach 5-8 unit/ton water; But facility investment is bigger, adopts in the Freshwater resources occasion that very plaque is weary; Because sun power belongs to low grade heat energy, need new breakthrough be arranged at the heat energy utilization technical elements.We know that the speed of evaporative process and evaporation total amount depend on heat transfer temperature difference and heat transfer area, the temperature head basic fixed of temperature when directly utilizing sun power to add hot sea water and seawater, and therefore increasing heat transfer area is key issue.Porous fiber has bigger specific surface area, utilizes this characteristic can increase heat transfer area.
People such as nineteen ninety-five A-A-AL-Karaghouli are based on the good wicking action of gunny cloth, a kind of solar floating gauffer type sea water evaporator is proposed, the gunny cloth that swims on the polystyrene board is made the height that gauffer shape floatation unit is arranged on about 5mm on the horizontal plane, the performance of this vaporizer is better than plain cloth formula and plane formula vaporizer, running maintenance is convenient, and maximum day output is 10.5 a liters/square meter.This vaporizer can be used for the water making device of resident living water on remote districts and the island.
