Dahan Technology Empire

After Liao Bin left the presidential palace, he visited a number of other powerful figures in power in Angola one after another. He sent flying cars and money to clear the way. In addition, the land that Qingquan Technology wanted was indeed the most barren Namib desert. In the name of the experiment, and promised to help Angola to green the desert free of charge after the results are obtained in the future.

Within a few days, Liao Bin received the approval of the Angolan government, and the two sides formally signed a cooperation agreement. Qingquan Technology exchanged new seeds worth 10 billion US dollars for the right to use 1,000 square kilometers of land along the Atlantic coast of the Namib for 30 years for scientific experiments. , study the technology of controlling arid deserts!

For the Angolan government, this is nothing but pie! A broken desert, nothing can be exchanged for 10 billion US dollars of new seeds, a few powerful people in power, everyone's pockets are bulging in an instant, not to mention these are new energy trees that can provide long-term sources of income. !

Moreover, Qingquan Technology is also very good at giving every person in power in Angola an atmospheric and beautiful Prosperous Tang Dynasty flying car, plus an activity fund that is unknown to the outside world!

For Qingquan Technology, the real cost is not too much. The seeds of 10 billion US dollars are only seeds, not cash. As for the cost of seeds, it has been reduced to a very low level! The real need to spend cash is to clear the way for those in power!

It didn't cost much to get a piece of land. Although the agreement was written for a 30-year right to use it for desert governance research, it was not that simple when it was in the hands of Qingquan Technology. Here is Qingquan Technology's plan to use it. As the most important retreat base!

1,000 Hercules cargo transportation flying cars are fully loaded with goods, and can transport millions of tons of materials at one time; 10,000 flying cars with the surname of Baijia transport all the construction workers in charge of construction at one time.

This time, Qingquan Technology set up a construction company by itself, recruiting construction workers, technical talents, etc. The overall environment is still not good, and there is a surplus of talents in the construction industry. Qingquan Technology can find all kinds of talents it wants with just one move.

Mo Qingming stopped his Prosperous Tang Dynasty flying car, and when he got off the flying car, a scalding heat wave hit, and the golden desert was like waves, forming countless beautiful crescents.

The place is extremely desolate. There are only some desert plants and cacti near the sea. Other creatures cannot be seen at all. There may be some desert snakes, scorpions, etc., but most of them are hiding in the hole at this time. in.

The sea is very clean, azure blue, corresponding to the cloudless blue sky connecting the sky, and the Buddha is like a reflection, which makes people feel open to one, there is a book business spirit, scolding Fang Qiu and pointing the country!

How is it? This piece of land is not bad! Liao Bin saw that Mo Qingming was in a daze,

He came over and patted his shoulder and said with a smile.

Thank you for saying that, more than 10 billion US dollars have been exchanged for this barren land. The company does not know how much money it would have to invest here to build a base that is similar! The barren land that is desolate and uninhabited still spends that much. Much! Mo Qingming shook his head.

He is really not very satisfied with this place. It's all desert and nothing. It's really desolate!

What I want is a barren and barren land. That's how the boss explained it to me back then. Now that the world has been divided up, this is the only place where our company can make great efforts. Otherwise, how can we hide it! Liao Bin also shook his head, there is no way, if the company wants to develop, it is natural to get rid of various restrictions from the country.

But all the lands on the earth already have owners, even the Antarctic ones have owners, uh, they are penguins! No matter which country the company goes to, it will be subject to various restrictions. It can only find a backward country, find a barren land, and slowly develop!

That's right! But then again, building a huge base in such a desolate place is also a huge achievement! Mo Qingming smiled very sullenly. For everyone in Qingquan Technology, everyone is young Man, what are you afraid of!

Let's take it step by step. The first thing that this future base needs to solve is the problem of water use. Without water, there is nothing, and our ability is useless!

That's right, this base was named Future, Future Base by Qingquan Technology!

Didn't you see the company put me out? Don't worry, our material company has already developed a variety of new materials for seawater desalination, plus other new desalination technologies, this place will be flooded in the future! Mo Qing Ming smiled proudly.

Liao Bin is not a technician. He is in charge of sales. He doesn't know anything about technology, so he can't help but be curious!

Hurry up and listen!

With Mo Qingming's slow introduction, the seawater desalination technology was fully displayed in front of Liao Bin.

Desalination is the use of seawater desalination to produce fresh water. It is an open source incremental technology to realize the utilization of water resources, which can increase the total amount of fresh water, and is not affected by time, space and climate, and can ensure stable water supply such as drinking water for coastal residents and industrial boiler replenishment.

The process of obtaining fresh water from seawater is called seawater desalination. The seawater desalination methods currently used include seawater freezing method, electrodialysis method, distillation method, reverse osmosis method, and the profitable ammonium carbonate ion exchange method. The reverse osmosis method has quickly occupied the market with its advantages of simple equipment, easy maintenance and modular equipment, and gradually replaced the distillation method as the most widely used method.

There are more than 100 scientific research institutions in more than 10 countries in the world carrying out research on desalination, and there are hundreds of desalination facilities with different structures and different capacities. A modern large-scale desalination plant can produce thousands, tens of thousands or even nearly one million tons of fresh water every day.

The cost of water has been continuously reduced, and in some countries it has been reduced to almost the price of tap water, and in some areas the amount of desalinated water has reached the scale of national and urban water supply.

At present, the mainstream seawater desalination technologies in the world are mainly traditional distillation method (thermal method) and reverse osmosis method (membrane method). Among them, low multiple-effect distillation method, multi-stage flash method and reverse osmosis membrane method are the global mainstream. Technology, distillation method is currently the most widely used, with the advantages of low seawater pretreatment requirements and high quality of desalinated water, but the disadvantage is that the energy consumption is serious and the dirt is difficult to deal with!

The reverse osmosis membrane method has the advantages of low investment and low energy consumption, but has high requirements for seawater pretreatment, that is to say, when using reverse osmosis method for seawater desalination, some treatment of seawater must be carried out in advance.

Of course, in addition to these two seawater desalination technologies, there is also a frozen seawater desalination treatment technology, which utilizes the triple point of seawater, even a special point where the three phases of seawater vapor, liquid and solid coexist and reach equilibrium. If the pressure or temperature deviates from the triple point, the balance is destroyed, and the three phases will automatically tend to one or two phases.

Vacuum freezing seawater desalination is a low-cost desalination method that uses the triple point principle of seawater and uses water itself as a refrigerant to evaporate and freeze seawater at the same time, and then separate and wash the ice crystals to obtain desalinated water.

Compared with the distillation method and the membrane seawater desalination method, the frozen seawater desalination method has low energy consumption, light corrosion and scaling, simple pretreatment, small equipment investment, and can handle seawater with high salt content. It is an ideal seawater desalination method. Law.

However, both the freezing method and the distillation method have insurmountable drawbacks. The distillation method consumes a lot of energy and produces a lot of scale in the instrument, but the fresh water obtained is not much; and the freezing method also consumes a lot of energy. The resulting fresh water, however, tasted bad and was difficult to use.

After listening to Mo Qingming's chatter, Liao Bin finally understood some knowledge of seawater desalination, and thought about it and said, How can you say that you have invented some kind of special material. Desalination of seawater with membrane method?

Mo Qingming smiled and said, Smart! I'm researching materials. Naturally, I start from materials, but your guess is not entirely correct. This time, I brought the latest researched seawater desalination membrane materials!

I don't understand your technology, how can this film desalinize seawater? When it came to technology, Liao Bin was at a loss.

Membrane separation technology refers to a technology that achieves selective separation of mixtures of molecules with different particle sizes at the molecular level when they pass through a semipermeable membrane. It is smaller than sodium molecules, so when designing this film, you only need to open the pores so that only water molecules can pass through! Mo Qingming explained patiently!

How easy is it? Liao Bin's eyes widened, it was hard to imagine that this seawater could be turned into fresh water just by passing through a simple membrane, then how could the whole world suffer from water shortages!

The principle is so simple, but this bionic material is very similar to biological cell membranes. Before we have developed new technologies, its cost is still very high, and the output is very low, so it cannot be promoted. The price is too expensive, we can only use the next-level reverse osmosis method to desalinate seawater through reverse osmosis. Now, just simply pressurize the seawater through the new material membrane to get fresh water! Mo Qingming smiled proudly. stand up.

The competition between the company, especially the research institute, is still very fierce. Everyone does not care about material things, but attaches great importance to the internal honor. After the material company accepted it from Mo Qingming, compared with other companies The research department is inferior, but he, Mo Qingming, has always been a high-ranking director and needs to show achievements that can convince others.

This time, the bionic filter membrane developed by Mo Qingming can realize fast, simple and low-cost desalination of seawater. It can be said to be a promising technology!

There are too many countries and regions in the world that are short of water! Not to mention other countries and regions, the Beijing-Tianjin-Tangshan region in the north of the country, the North China region, and the northwest inland region are all very short of water, which has seriously hindered the development of all aspects of society. With new materials, there will be an inexhaustible supply of water, and you can use it how you want! (To be continued.):
