Abstract
The utility model relates to a solar energy sea water desalting device which belongs to a device utilizing the solar energy for the desalination of sea water and whose main part comprises a paraboloidal mirror, a heater with a pipe extending to the outside, a group of heat exchangers, pipes, a valve, etc. When the symmetry axis of the paraboloidal mirror is in the same line with the sun, the water contained in the heater is heated to boil to generate water vapor which produces fresh water after the condensation by flowing through the heat exchangers. The energy released from the condensation is transferred to the sea water in the other passage of the heat exchanger, and the sea water is supplemented into the heater after preheated to connect the whole device for fresh water production. The desalination of the sea water by using the utility model is economical and practical.
Description
The utility model is a kind of device that utilizes sun power to desalinize seawater.Classification number CO2F1/14.
At present created method and equipment that ion exchange method or the like desalinizes seawater, but all had output few, cost height, the shortcoming of complicated operation.Therefore, also do not occur as can production prices cheap fresh water and the method and apparatus that desalinizes seawater that can widespread use.
Fresh water and air, food is the same is the fundamental of keeping people's life, for ride the sea, the people of operation and do not have the islander of fresh water artesian well, general its used fresh water all will ship from land or island that fresh water is arranged, and these fresh water are especially expensive because of the difficulty of its transportation.When particularly running into stormy waves and some other situation, the transportation of fresh water has just had difficulty, and the people on Yu Haiyang ship in danger, lacks normally one of their greatest difficulty of surviving down of fresh water.
The utility model provides a kind of makes the above-mentioned people that those sink into awkward situation can utilize the equipment of the sea water desaltination of theirs on every side for fresh water.
Of the present utility model theing contents are as follows:
One, parabolic mirror, when the adjustment angle made its parabolic symmetry axis and the sun on same straight line, its focus place has can heat water to ebullient high temperature.
Two, sealed vessel that two pipeline pass-outs are arranged, we are referred to as well heater, and the bottom of well heater places on the focus of parabolic mirror, and the bottom of well heater fills seawater, but water is not full of whole well heater.Water in the well heater is by aforesaid parabolic mirror focused solar ebuillition of heated.Water vapor does not have the hydrospace by the well heater top and draws through the pipeline that we are referred to as fresh water pipe, the pipeline that water is referred to as the seawater pipe by we of heating tube bottom is introduced and is replenished, the water vapor that the seawater ebuillition of heated is evaporated is the same with the water vapor composition in the overhead cloud layer that forms in ocean in theory, and their condensed products all are fresh water.
Three, fresh water pipe links to each other with well heater respectively with an end of seawater pipe, and the other end links to each other with a heat exchanger respectively.This heat exchanger can be simply connected or multi-joint.Seawater enters well heater from bottom to top after the heat exchanger preheating, water vapor from top to bottom is condensed into water after the heat exchanger heat radiation.Water of condensation flows out fresh water pipe, puts into water container, and fresh water has just been produced.
Four, seawater enters well heater along the seawater pipe by heat exchanger from a water tank.Water tank is higher than well heater to obtain a forward head.Seawater pipe between well heater and the water tank is provided with a sea valve, in order to the water level in the control heater.
Five, production fresh water process of the present utility model is: utilize the sunlight projection of well heater on parabolic mirror earlier, adjust the angle of parabolic mirror, make the symmetry axis of parabolic mirror and the sun point-blank, the part seawater will be added again in the well heater, utilize sun power that water is heated to boiling then, water vapor becomes fresh water after the over-heat-exchanger condensation.The energy that water vapor condensation discharged reaches in the seawater in another passage of heat exchanger, high temperature seawater through the over-heat-exchanger preheating adds in the well heater, at this moment the seawater in the well heater is a vaporization heat as long as absorb conversion of solar energy, just can produce water vapor, whole device also just can be produced fresh water continuously.
Principle of the present utility model is simple, and facility investment is little, is easy to installation and maintenance, and raw material is sunlight and seawater, almost need not what cost, easy to operate easy, and aquifer yield is big, and unit cost is low, can continuous production.
Accompanying drawing is the synoptic diagram of an example of the present utility model " portable type solar energy fresh-water generator ".Sunlight (1) focuses on well heater (3) by parabolic mirror (2), make seawater (4) boiling back in the well heater (3) become water vapor to enter heat exchanger (6) vapour fresh water (7) back of congealing into and flow into container (8) by fresh water pipe (5), seawater (4) by water tank (9) after heat exchanger (6) preheating sea valve (10) and seawater pipe (11) enter well heater (3) and enter additional the seawater (4) of well heater (3) lining.The additional of seawater (4) is to carry out according to the situation of watermark (12).Sea valve in this example (10) is a threeway, when well heater needs moisturizing, seawater (4) flows into well heater (3) by heat exchanger (6), when well heater does not need moisturizing, seawater (4) is discharged by water discharge pipe (13), makes heat exchanger (6) strengthen the condensation operation under the situation of needs.
Parabolic mirror (2) adopts " folded umbrella formula parabolic mirror " in this example.The building up principle of its skeleton is the same with common umbrella.In order to improve the rigidity of skeleton, the support group of this example skeleton increases to nine groups by eight groups of general umbrella, and bar cross section strengthens, and makes with manganese steel, minute surface is opened after, the shape of its skeleton is able to accurate control.The umbrella cover that is different from umbrella is that the minute surface of this example is to be positioned at the skeleton inboard in the skeleton outside, and its material adopts the lining of photography user front-surface mirror.Its lining characteristics are that reflective is good, high strength, low elasticity, and flexibility can be rolled over.
Watermark (12) on the well heater (3) is the sealing watermark, and its two ends partly communicate with Sheng vapour with the part that is filled with water of well heater respectively, so that whether the user determines to the well heater moisturizing according to the expression situation.Heater base heating position in this example is a black, and does not have pipeline configuration, and top is for white and be covered with lagging material, can improve thermo-efficiency like this.The top of the bottom of black and white is to separate manufacturing and be coupled to sealed vessel with fastening piece simultaneously, can regularly pull down fastening piece so that remove the interior saliferous incrustation scale of well heater.
Heat exchanger (6) is the form that a spiral heat transmission fresh water line is established in the inside of employing seawaterline in this example.
This example can be used as the basic outfit on the seagoing vessel liferaft, at ordinary times parabolic mirror is folded the back as one, well heater is as one, and pipeline and heat exchanger are as one, add structure and connect other parts, all be placed on the liferaft in the very little chest of volume.When after running into the perils of the sea, taking advantage of liferaft to arrive an island, do not have fresh water sources probably, at this moment folded umbrella formula parabolic mirror can be strutted, refill upper heater, heat exchanger and structure junction piece, produce fresh water to save oneself.
