Chapter 557 Magical desalination technology(1/2)
After the rocket launch farce,
This day has arrived, April 10th.
Mu Yang began to design seawater dehydration technology and analyzed the advantages and disadvantages of several dehydration technologies.
Like electrolytic dehydration, it is a method of water treatment that uses electricity. It electrolyzes the salt in the aqueous solution and converts the salt into chlorine and hydrogen, thereby achieving the purpose of dehydrating water.
This method can be used in any place, but it requires a large amount of power support, so the cost is high when used on a large scale. It is not suitable for Muyang's large-scale dehydration treatment method. Another example is the evaporation crystallization method, which is to heat seawater
Evaporate and cool it to become water, which is suitable for large-scale seawater dewatering.
Another example is the condensation method, which evaporates seawater into steam and then cools the steam into liquid water, which is suitable for seawater with low salinity.
There are many other methods, each with different usage methods for different salinities.
However, currently existing methods are not suitable for large-scale seawater dewatering in Muyang.
Therefore, Muyang needs to find a new seawater dewatering technology from the system to meet its large-scale needs, and must consider cost and sustainability.
At the same time, we also need to consider protecting the marine environment and reducing the impact on the marine ecosystem.
Open the reading system, achievement point store, and ordinary shelf.
Search for "Dan water treatment technology", filter out the conventional technologies, and look at the technologies he doesn't know first.
In an instant, many technologies were searched, many of which were in science fiction, such as glacier extraction method, solar distillation method, laser desalination method, magnetic desalination method, biocomposite membrane method, sieve ion exchange method, etc.
Many technologies are temporarily unavailable in real life, but they can shine brightly in science fiction works.
It sounds a bit incredible, but I didn't expect that this technology actually exists in the reading system.
Mu Yang was very curious and browsed the introductions of these technologies one by one.
"Laser desalination method uses powerful laser beams to treat seawater so that the salt in it is destroyed and discharged, thereby obtaining fresh water.
But it just consumes electricity and the cost is not low.”
"Forget it, this glacier extraction method is only suitable for the North and South Pole where there are glaciers. Where would the water come from without ice?"
"The cloud guidance method is a good idea, but if there are mountains thousands of meters above sea level blocking it, it can't be stolen. If possible, I really want to steal Asan's clouds secretly, but those peaks,
Continuously.”
"Hey, the magnetic desalination method is a very novel idea. The problem is that sodium chloride is not iron, so can it be affected by magnetism?"
When Mu Yang saw this technology, he was really curious.
Open the introduction and you will probably understand what it means. It uses a magnetic field to act on the salt in seawater to deposit it at the bottom of the seawater, thereby achieving water treatment.
The thickness of seawater cannot exceed one meter, otherwise the impact will be small.
Mu Yang didn't understand the specific principle. How does the magnetic field act on the salt in seawater?
If this dissolves into seawater, and it is not a magnetic substance, how will it affect it?
He was puzzled.
If it can really be realized, the power consumption will be very small, because it only needs to continuously provide power to the equipment, which is very suitable for large-scale dehydration.
I have to say, it’s very impressive.
Mu Yang really wanted to buy this technology and looked at the achievement point requirements.
"Wow, 1,000 points!"
“It’s so expensive!”
"Damn it, black technology is expensive."
There are too many achievement points in demand, so Mu Yang continues to learn about other dehydration technologies.
After two hours, he understood all the dehydration techniques.
One is the sieve ion exchange method, which uses a sieve ion exchanger to remove salts and impurities from seawater to obtain fresh water, which is more suitable for purifying domestic water. It requires 500 achievement points and is also quite expensive.
The other one is the magnetic desalination method that Mu Yang can't figure out.
He was a little hesitant and had to be cautious. The achievements were not easy to come by.
After struggling for a while, Mu Yang finally decided to buy it.
As long as the eternal project is done well, there will be no shortage of achievement points in the future. Without investment, there will be no gain.
First spend a thousand achievement points to buy the technology of magnetic desalination device.
After a few minutes, you will have absorbed this technical knowledge.
Mu Yang knows that the magnetic desalination method uses the magnetic properties of magnetic fields to desalinate metal elements such as sodium, lithium, rubidium, and potassium to achieve desalination.
Generally speaking, magnets cannot absorb metallic elements such as sodium and potassium because they are not magnetic substances. It can only absorb magnetic metallic elements such as iron, nickel, and cobalt.
Moreover, iron elements may not necessarily be adsorbed, such as austenitic stainless steel 304, which also contains iron Fe, but it has almost no magnetism because the main structure is austenite, not ferrite.
But if it is martensitic stainless steel or duplex stainless steel, if there is ferrite in the structure, it will be magnetic.
Like aluminum, it is non-magnetic.
Therefore, this magnetic desalination method is also something that makes Mu Yang feel incredible. The magnetic field here does not refer to a "ferromagnetic field."
It's a new type of device that can affect metal elements.
However, non-metallic impurities cannot be affected.
The emergence of this new type of equipment will undoubtedly bring revolutionary changes to the field of pollution control.
“This device is really a black technology!”
“1,000 achievement points is expensive, but it’s worth it!”
Mu Yang was deeply shocked and looked forward to seeing the finished product.
Next, Mu Yang began to understand the equipment's ability to process seawater.
The water inlet of this equipment can be expanded to 10 meters wide, the maximum affected water depth is 1 meter, and the maximum allowed flow rate is 5 meters/second.
The theoretical maximum seawater processing capacity is 50 cubic meters per second!
too exaggerated!
In other words, if equipment maintenance and cleaning of metal impurities are not considered, 180,000 cubic meters can be processed per hour!
That’s 4.32 million square meters per day!
Equivalent to 4.32 million tons of water!
too exaggerated!
Of course, it should be noted that this is only the theoretical maximum value, and various uncertain factors must be taken into consideration in actual operation, such as seawater quality, equipment maintenance and impurity cleaning, etc.
But no matter what, the processing capacity of this equipment is amazing and can effectively alleviate water shortage and water pollution problems.
Generally speaking, big cities consume a lot of domestic water every day, including drinking water, bathing water, washing water, toilet flushing water, etc. It is estimated that each person needs to use 100-200 liters of water a day, which means a population of 10 million
Cities consume 1 million to 2 million tons of water every day.
At the same time, cities also need water for public facilities, industrial production, irrigation, etc., so the total water consumption in cities every day may reach millions or even tens of millions of tons of water.
Of course, domestic water needs further treatment and purification, so magnetic desalination equipment is not suitable.
But as long as it is treated into water, it is much easier to further purify it into domestic water.
This also means that even including equipment maintenance time and time for cleaning salt crystals, only three pieces of equipment are needed to support the water supply problem of a city worth tens of millions.
In terms of equipment consumption, the power of a piece of equipment is not small. Because the equipment occupies a large area, the power of the equipment reaches 2,000 kilowatt hours.
The electricity consumption is 1000-2000 kWh per hour.
After all, one kilowatt hour of electricity can process 90-180 tons of water!
Of course, this is just the cost of electricity and can be ignored.
Before seawater enters the equipment, it must undergo preliminary treatment of impurities, such as sand, seaweed, etc. The method is to first pass through a sedimentation tank, then filter through a multi-layer physical screen, and finally flow into the magnetic desalination equipment.
If you don’t include equipment costs and site construction costs, the treatment cost per ton of water is extremely low, less than a penny.
One piece of equipment occupies a very large area, more than 10,000 square meters, and costs about 500 million yuan.
If the equipment has a service life of 10 years, it is estimated that it can process about 15 billion tons of water, and the average cost of the equipment is 3.3 cents per ton of water.
Taking into account the costs of operations, labor, energy, environmental treatment, etc., after comprehensive calculation, the comprehensive cost per ton of treated water is about 5-10 cents, and the cost of domestic water treatment is more.
If it is to be transported to the west, the construction and maintenance of pipelines and waterways will also need to be considered during the water transportation process, and the cost will increase accordingly. Mu Yang cannot estimate it for the time being.
In short, preliminary estimates suggest that 10 magnetic desalination equipment are enough to divert water from the east to the west.
If we include water use in cities and water supplies in various river basins along the way, 5 more pieces of equipment need to be added.
If all the water processed by one equipment is transported, the maximum amount per year is 1.5 billion cubic meters, which is equivalent to a lake with an area of 100 square kilometers, and the average water depth reaches 15 meters!
Excluding equipment maintenance factors, at a discount, one piece of equipment can actually process 1 billion tons of water.
In fact, Mu Yang initially ignored an influencing factor.
When there is enough moisture in the desert, the humidity in the air will increase, and a new water circulation system will be formed in the local area, which has changed.
