Background technique

At present, there are many seawater desalination methods used at home and abroad, disguised phase method: evaporation method, distillation method, cooling method; membrane separation method: reverse osmosis method, electrodialysis method; chemical equilibrium method: ion exchange method, hydration method, solvent extraction method and other three main types. At present, the leading technology and the most widely used is flash distillation, which accounts for about 70% of the world's total desalination production. The flash distillation method is to use the characteristic that the boiling point of water decreases with the decrease of pressure. First, the seawater is heated in the pipeline, and then introduced into an evaporation chamber with a lower pressure. The introduced high-temperature seawater will evaporate rapidly in an instant. (It stops after a short period of evaporation saturation), and the generated steam is condensed outside the pipeline with cold sea water to form fresh water. Its disadvantages are: high investment in equipment, large seawater circulation, small water production, slow water production, low concentration rate, and high operating costs. There are few records in the literature about the technology of gas-liquid mixing and high-speed evaporation of seawater desalination.

When the tiny mist droplets ejected by the atomizing nozzle 6 at high pressure and high speed and the fast air flow ejected by the remote turbo blower 7 [or fan 7] pass through the mixing chamber 8, a low pressure is generated in the mixing chamber 8, and the air with a slightly slower flow rate is sucked in. Air flow, high-pressure, high-speed micro-droplets and fast air flow are fully mixed and then enter the diffuser 9 together. When passing through the diffuser 9, the pressure of the mixed fluid gradually rises again, and the vapor-liquid mixture 10 is formed after the tiny mist and the air flow are mixed more uniformly, and then discharged from the diffuser 9 and sprayed into the air at a high speed from the mixture outlet 22.

The transparent vaporization greenhouse 11 is a huge transparent solar radiation heat collection cover; the middle and upper part of the body of the transparent vaporization greenhouse 11 is provided with a single or 2 or more fully sealed and isolated transparent louver partitions 13, which can isolate a single or 2 One or more than two vaporization chambers 14, the vaporization chamber 14 is arranged on the upper part of the body of the transparent vaporization booth 11, and the bottom of the vaporization chamber 14 is provided with a distilled water outlet valve 20, and the transparent louver interlayer plate 13 can force the water vapor flowing upward to only Enter into the vaporization chamber 14 in one direction. The volume of the giant transparent solar energy transparent vaporization greenhouse 11 is large or small, and its volume should be set in order to satisfy the huge amount of vapor-liquid mixture 10 that must absorb a large amount of heat around when it is continuously atomized and vaporized. Large and small (provide sufficient space for the separation of gas and concentrated brine droplets, therefore, this huge space cover greenhouse can borrow the unique advantages of its huge transparent cover for solar radiation hot collection). The volume of its transparent vaporization greenhouse 11 should be based on the different needs of different finished product water quality, the needs of different working gas flow, different water flow, different water flow velocity and different working pressure. The setting range is 100 times to 100,000 times of the flow volume of the pressure infusion valve 4 per minute. The lower part of the transparent vaporization greenhouse 11 is provided with an interval isolation plate 12. The interval isolation plate 12 is a large-area plane body. The interval isolation plate 12 is perpendicular to the bottom of the transparent vaporization greenhouse 11; The pressure relief and exhaust window 15 can automatically open the pressure relief and exhaust and automatically close to stop the pressure relief and exhaust according to the change of the air pressure difference in the transparent vaporization greenhouse 11 body. The bottom of the transparent vaporization greenhouse 11 is equipped with a solar blackened heat-absorbing concentrated brine pool 16, a solar blackened heat-absorbing fresh water pool 17, a concentrated brine outlet valve 18, and a fresh water drainage valve 19; the concentrated brine outlet valve 18 and the concentrated brine pool 16 Connect, the fresh water drain valve 19 is connected with the fresh water pool 17; the solar energy blackening heat absorption concentrated brine pool 16, the solar energy black heat absorption fresh water pool 17 are solar radiation heat energy collection pools.

The working process of the gas-liquid mixing high-speed evaporation seawater desalination device of the utility model is as follows: firstly, the pressure water inlet valve 1 is opened to continuously inject the pretreated cold seawater at high speed into the water storage tank 2 through the pressure water inlet pipe, and the pressure is opened. The power switch of the water pump 3, when the working pressure of the pressure water pump 3 reaches a certain high pressure required by different water quality requirements of different finished products, turn on the power switch of the remote turbo blower 7 [or fan 7], and then turn on the pressure infusion valve 4 High-pressure and high-speed spray tiny droplets into the hurricane hood 5 through the atomizing nozzle 6, and a huge amount of high-density air flow enters from the gas inlet port 21 of the hurricane hood 5 and mixes with the high-pressure and high-speed seawater particle spray beam. When the high-pressure seawater When the particle spray fluid is sprayed out of the atomizing nozzle 6 at high pressure and high speed, a low pressure is generated in the mixing chamber 8, and the air fluid with a slower flow rate is sucked in to mix with the particle droplets, and enter the diffuser 9 together, and pass through the diffuser 9 At this time, the pressure of the mixed fluid gradually rises again. After the tiny mist and the air flow are mixed more evenly and dissolve each other in two directions, a vapor-liquid mixture 10 is formed, and then sprayed out of the diffuser 9 at a high speed, from the mixture outlet 22 It is sprayed into the air at high speed, and is quickly evaporated and vaporized while further dissolving each other in two directions.

After the vapor-liquid mixture 10 is ejected, it quickly absorbs a large amount of surrounding heat while forming suspended small particles, and rapidly expands tens of times, hundreds of times. Because the fresh water liquid is easy to expand, the small fog droplets form fog clouds after expansion. The relatively volatile components are easy to evaporate. The vaporized fresh water droplets have small particles, small particles, large volume, and small specific gravity. After being sprayed and transported by high-speed airflow, the drifting journey is long, and they are suspended for a long time and a long distance Drift and decline slowly, forming fine suspended fog cloud particles, which are quickly evaporated and vaporized under the high temperature of solar radiant heat in the transparent vaporization greenhouse 11; the particles that are not easy to evaporate, the small droplets of concentrated brine that are not easy to evaporate and vaporize, have larger particles and larger particles , the volume is small, the specific gravity is relatively large, and after being transported by the high-speed airflow, the drifting stroke is short, the suspension drifting time is short and the drop is fast, and the tiny liquid droplets are evaporated under the high temperature of solar radiation heat in the transparent vaporization greenhouse 11. Vaporization is slower and fall is faster. The seawater liquid mist is transported by the high-pressure high-speed jet beam of the pressure water pump 3 and the huge jet air flow of the remote turbo blower 7 [or fan 7], and the high-density gas is continuously stirred for a long time and transported for a long distance, The long-term long-distance suspension drift forms fine suspended mist droplets that are continuously assimilated by a huge amount of air flow, continuously move up, and are continuously evaporated and vaporized by the high-temperature solar radiation heat in the transparent vaporization greenhouse 11 .

A large number of suspended small mist droplets are sprayed and transported for a long time and long distance by the huge and fast jet airflow of the remote turbo blower 7 [or fan 7]. When the huge and fast jet airflow is sprayed and transported for a long time and long stroke, when it is continuously and slowly descending, the single or multiple remote turbo blowers 25 [or the fan 25] of the relay form are turned on at this time, The huge amount of fast air flow produced by the remote turbo blower 25 [or the fan 25 of the relay form] of single or multiple relay forms will blow up a large number of suspended small mist droplets and fine particles that are slowly drifting and gradually descending and send them to the air for a long time. The stroke runs and drifts, and the continuous stirring, separation and isolation force all the fine suspended mist droplets to float and drift for a long time in the air inside the transparent vaporization greenhouse 11, forming a suspended vapor-liquid mixture 10 that is repeatedly repeated for a long time with a large amount of air and gas. After fully stirring and mixing, the suspended vapor-liquid mixture 10 is easily assimilated by air, so that it is continuously vaporized by high temperature and rapid evaporation. At this time, the automatic exhaust window 15 is continuously and automatically transported out quickly after a large amount of unnecessary gas in the transparent vaporization greenhouse 11 is accumulated in the continuous change according to the air pressure. Because the concentrated brine droplets stay in the air for a short time, the stroke of the suspension drift is short, and the drop is fast, and they are collected into the concentrated brine pool 16 that is blackened and absorbed by the solar energy under the separation of the interval isolation plate 12; The fine mist droplets stay in the air for a long time and have a long journey of suspension and drift; they descend slowly and collect into the fresh water pool 17 that is blackened by solar energy and absorbs heat under the separation of the section isolation plate 12 . Under the auxiliary heating effect of high-efficiency solar energy, the transparent vaporization greenhouse 11 quickly evaporates and vaporizes the fine suspended vapor-liquid mixture 10 wandering in the air, and the huge amount of fast-flowing water flow carries a large number of suspended small mist droplets to run up at the same time. After part of the fine particles are evaporated and vaporized, part of the rising water vapor flow enters the upper vaporization chamber 14 from the louver hole of the transparent louver interlayer plate 13 with one-way entrance, and then evaporates and gathers to form distilled water. Finally, open the concentrated brine outlet valve 18 to continuously discharge the concentrated brine solution; open the fresh water discharge valve 19 to continuously discharge the fresh water solution; open the distilled water outlet valve 20 to continuously discharge the distilled water solution; achieve low consumption The purpose of gas-liquid mixing high-speed evaporation seawater desalination for long-distance separation for long-distance separation.
