Description
Technical field
The present invention relates to sea water desaltination and water-treatment technology field, particularly relate to a kind of fresh-water generator with preheat function.
Background technology
Freshwater resources are not enough in the world, become people's problem day by day deeply concerned, and as the increment technique of increasing income of water resources, sea water desaltination has become the important channel that solves the global water resources crisis.Sea water desaltination namely utilizes sea water desalinization to produce fresh water, mainly contain reverse osmosis method and distillation method at the many desalination technologies of China's usage comparison at present, wherein reverse osmosis method claims again the ultra-filtration method, the method is to utilize the semi-permeable membranes that only allows solvent to see through, do not allow solute to see through, seawater and freshwater is separated, but the cost of reverse osmosis method and cost of use are higher, have disposablely to have high input, conventionally consume the defectives such as larger.Distillation method is to make it the boiling vaporization by heating seawater, then vapor condensation is become the method for fresh water.The distillation sea water desalting technology is to throw the earliest the desalination techniques of people's industrial applications, even characteristics are also applicable in the briny environment of seriously polluted, high biological activity, produce water purity high, compare with the osmosis method for sea water desalination technology, distillation method has the low-grade heat that can utilize power plant and other factories, throughput low to the raw material seawater water quality requirement, device is large, is one of mainstream technology of current sea water desaltination.Existing a kind of tubular type sea water desalinating plant, by put into heating tube in the pipe that is filled with water, make the water evaporation in Storage water tank rise to the then condensation of top of outside solidifying water pipe, thereby fresh water is accumulated in bottom outer water tube, because its high yield water efficient, low cost, suitability are strong, obtained extensive concern.But simultaneously, it also exists certain defective, and the heat that vapor condenses becomes the fresh water process to distribute is not fully utilized, but directly is dispersed in air, causes the device efficiency not high.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of fresh-water generator that can install efficiency.
technical scheme of the present invention is as follows: a kind of multi-level tubular fresh-water generator with preheat function comprises shell (1) and Storage water tank, described Storage water tank is arranged on shell (1), and be provided with heating tube (3) in this Storage water tank, this heating tube (3) is arranged in Storage water tank vertically, it is characterized in that: the tube wall of described shell (1) is the hollow structure with internal cavities (1b), and be injected with seawater in this internal cavities (1b), one end of described internal cavities (1b) is connected with inlet chest (5) by water inlet pipe (4), the other end is connected with Storage water tank by rising pipe (6).
When adopting above structure to carry out sea water desaltination, seawater is injected in enclosed space by water inlet pipe from inlet chest, inner heating tube heats the water in Storage water tank, thereby the water in Storage water tank is evaporated on the inwall of shell.The heat of water vapour passes to water in enclosed space by shell, thereby makes the steam coagulation on outer casing inner wall, then gathers along outer casing inner wall landing to outer casing bottom.And after the water in enclosed space is heated again, is injected into by rising pipe again and processes in Storage water tank, being fully utilized of the heat that this structure produces when causing steam coagulation improved the efficiency of device greatly.
Be set with successively from outside to inside one-level Storage water tank (2a), B-grade condensation sleeve pipe (8b), secondary Storage water tank (2b), three grades of condensation sleeve pipes (8c) and three grades of Storage water tanks (2c) in described shell (1), only be provided with heating tube (3) in three grades of Storage water tanks (2b), the bottom of the bottom of B-grade condensation sleeve pipe (8b), three grades of condensation sleeve pipes (8c) and the bottom of shell (1) all are connected with water tank (11) by communicating pipe (10).Moisture in the Storage water tank of innermost layer is evaporated to its outer field condensation jacket cooling and then gathers, then the condensation sleeve pipe transfers heat to the seawater in his outer Storage water tank again, heat energy utilizes from level to level, water in outermost Storage water tank is evaporated on shell, and heat passes to the seawater in enclosed space again.Take full advantage of heat, waste, further do not improved efficiency.
In order to improve the insulated capacity of Storage water tank, be equiped with thermal insulation layer (9) at the inwall of described Storage water tank.
In order to improve the contact area of heating tube and Storage water tank maritime interior waters, improve the heating efficiency, be evenly distributed with a plurality of radiated ribs (7) on the outer tube wall of described heating tube (3), each radiated rib (7) is axially installed along heating tube (3).
In order better to heat the Storage water tank maritime interior waters, described heating tube (3) is " U " shape pipe.
Beneficial effect: the heat that the present invention produces when making vapor condenses become water carries out preheating to the seawater of shell internal memory storage, again the seawater of preheating is further desalinated, save the energy, improved the efficiency of device, also had simultaneously energy-conserving and environment-protective, the characteristics such as simple in structure.
