Dodging anxious distillation method is exactly to utilize the boiling point of water to reduce this characteristic with pressure, seawater is heated in pipeline, guide to then in the lower evaporator room of pressure, the high temperature seawater that is introduced into will evaporate rapidly between in an instant, and the steam of generation obtains condensation and causes fresh water outside the pipeline that Mare Frigoris water is housed.Its shortcoming is: equipment is huge, and the seawater internal circulating load is big, the system water yield is little, the low process cost of enrichment factor is higher.(need large batch of seawater to make, get only 1 part of fresh water, but will produce 9 parts of concentrated seawaters that pollution is arranged).
The purpose of this invention is to provide a kind of efficient sea water desalting equipment, it is simple in structure, less investment, volume are minimum, stable performance, incrustation scale is few, easy to use, water outlet is fast, cost is low, go out fresh water amount very high (9 parts of fresh water, only produce 1 part of strong brine).
In order to achieve the above object, solution of the present invention is: utilize seawater in high temperature, the fresh water molecule volatilizees easily, and proportion, rate of expansion change greatly; The strong brine molecule is not volatile, and proportion, rate of expansion change less.According to the bigger characteristic of difference in specific gravity between the molecule of seawater heating back, adopt the difference in specific gravity partition method to desalinize seawater.Seawater in the high speed rotating of ultra-high speed whizzer in high temperature comprehensively under the prerequisite of boiling vaporization (after reaching super-high density ' priming ' state), (seawater is in high-boiling, it is owing to containing more volatile components, so along with the rising volume and the proportion of temperature changes very greatly that the fresh water molecule is alleviated by high-temperature evaporation volume increase proportion easily; It is owing to containing more difficult volatiles, so along with the rising volume and the proportion of temperature changes very little that the strong brine molecule is difficult for by high-temperature evaporation.) make its proportion maximum distribution of particles in the periphery, the particle of proportion minimum is near turning axle, reaches to separate purpose and they are kept apart.In getting rid of the build boiler body, settles heating container one or more layers sealing coat, after injecting pre-hot sea water and suspended substance, carry out the rapid heating vaporization, be placed on the ultra-high speed whizzer and adopt the rotation of ultra-high speed centrifugal force to isolate different specific gravity liquids getting rid of the build boiler, in getting rid of the build boiler body, establish one or more layers sealing coat check valve and isolate different specific gravity liquids, the lighter mixed solution (saturation water and wet saturated steam) of proportion of the water of separator well and steam two-phase coexistence is transported in the quick cooling chamber with getting rid of in the build boiler, and being cooled off fast to condense by the overlapping spiral coil cooling tube of settling in the quick cooling chamber of the multilayer of filling with Mare Frigoris water promptly becomes fresh water.Get rid of build boiler bottom and be provided with the strong brine discharge outlet, so constantly circulation repeatedly.
Technical scheme of the present invention is as follows: get rid of the closed boiler of build and be made up of three parts, top is provided with pre-hot sea water transport pipe water-in and gas check valve conduit air inlet, the middle part is provided with one or more layers sealing coat, the sealing coat check valve is set in the bottom, boiler body is provided with high temperature mixed solution discharge outlet outward and is communicated with water pump and water level displaying tube is set, and the bottom is provided with the strong brine discharge outlet; Sealing coat is middle foraminous sealing coat panel; Suspended substance can replace reusing with rice husk; It is the one-way cock of only export but no import that the sealing coat check valve can adopt the magnetic valve working forms; The ultra-high speed whizzer is a ultra-high speed stereoscopic multi-layer combined type special centrifugal machine; Quick cooling chamber is that the built-in overlapping spiral coil cooling tube of multilayer of filling with Mare Frigoris water is convenient to quick cooling, cooling room top is provided with two apertures, one aperture is a high temperature mixed solution admission port, another hole is a preheating water pipe water outlet, the bottom also is provided with two apertures, one hole is the fresh water water outlet, and another hole replenishes the liquid import for Mare Frigoris water and is communicated with water pump.
The workflow of efficient sea water desalting equipment is; 1. Mare Frigoris water heating: open Mare Frigoris water water intaking valve earlier, Mare Frigoris water replenishes liquid and is delivered in the water-cooled tube of quick cooling chamber bottom by water pump, because the overlapping snakelike water-cooled tube of multilayer soaks to be embedded in and can obtain step by step from bottom to top preheating in the cooling room of filling the high temperature mixed solution, import again and get rid of in the build boiler body, when reaching about 60% water level, the preheating sea level fluctuations (shows) switch and boiler preheating seawater water inlet valve of switching off the pump and Mare Frigoris water inlet valve by water level displaying tube.The power system of ultra-high speed whizzer can be opened, inferior opening got rid of the heating of build boiler heat source switch, whizzer begins to do the centrifugal body rotation speed of rotation of getting rid of and accelerates gradually, the intravital high temperature seawater of boiler seethes with excitement comprehensively when whizzer reaches maximum speed, water and steam two-phase coexistence mixed solution are under the cooperation of help of having put a certain proportion of suspended substance and sealing coat, reach super-high density ' priming ' state of comprehensive homogeneous fully, (having water water that vapour is arranged in the comprehensive abundant intimate mixing vapour) enlarges the difference in specific gravity between fresh water molecule and the strong brine molecule to greatest extent, and volume increases considerably proportion and alleviates significantly.(the fresh water molecule of this moment be in active state, mean kinetic energy increase to maximum, run out of the water surface in the unit time and the backwater that falls in molecule at most, the distance between the fresh water molecule strengthen many, volume greatly every degree increase, proportion alleviates significantly.) owing to strong brine is difficult for being kept apart when valve is closed at peripheral coverlet as the distribution of particles of proportion maximum by high-temperature evaporation; The particle steam of proportion minimum is kept apart during also by the check valve closure near turning axle.Can close sealing coat check valve switch and ultra-high speed whizzer propulsion source this moment simultaneously, and inferior closing got rid of the build boiler heat source, stops the rotation until whizzer.
2. produce fresh water: open boiler bottom water and steam two-phase coexistence high temperature mixture fluid valve earlier, allow the high temperature mixed solution pour in quick cooling chamber, inferiorly open the fresh water flowing water Valve and pump switch discharges water, (the gas unidirectional valve is worked automatically) when high temperature mixed solution (saturation water and wet saturated steam) in case enter just be cooled a large amount of Mare Frigoris water in the overlapping spiral coil cooling tube of multilayer of indoor arrangement of quick cooling chamber and cool off to condense fast and be converted into fresh water.After the intravital high temperature mixed solution of boiler was all discharged, promptly switch off the pump switch and high temperature mixture export valve switch and discharging fresh water valve switch were opened boiler body bottom valve switch and sealing coat check valve switch discharging strong brine at last.So constantly move in endless cycles repeatedly.(about 10 minutes of circulation primary).
Owing to adopted the sea water desaltination of difference in specific gravity partition method in the above-mentioned solution, only need that the seawater ebuillition of heated is presented ' priming ' state and force the difference in specific gravity that produces maximum between fresh water molecule and the strong brine molecule, isolate fresh water and strong brine with the ultra-high speed whizzer then and they are kept apart.It is simple in structure, less investment, stable performance, power consumption less, little, the system water express train of volume, incrustation scale few (and being convenient to remove), cost be low, it is high especially to go out fresh water yield, (being particularly suitable for the concentrated seawater desalination) can use in various fields.Really accomplish what the nearly one thousand years people looked forward to always: cost is low, volume is little, cheap, the popular sea water desalinating plant of popularizing in an all-round way that output is very high.
