Graphene or carbon nanotube thermal film saline water treatment equipment and control method

the invention relates to graphene or carbon nanotube hot film saline water treatment equipment and a control method.

Background art:

at present, the waste heat power generation device developed by people can directly use waste gas and waste liquid with the temperature of more than 80 ℃ to generate power. Therefore, a multi-effect flash seawater desalination method using a steam turbine engine with wastewater steam of 200 ℃ and a multi-stage flash seawater desalination method using industrial waste heat to heat seawater to 70 ℃ will be eliminated. The large-scale seawater desalination only remains the reverse osmosis seawater desalination method. The temperature of seawater required for reverse osmosis seawater desalination is higher than 20 ℃, and the lowest temperature of the seawater in the Bohai sea in winter is 0 ℃. The viscosity of seawater at 0 ℃ is too high, and the seawater desalination is not suitable for the reverse osmosis method. The central line south water north transfer project transfers the Yangtze river water from the mouth of the Danjiang river of Hubei to Beijing, and the cost of each ton of water is 8 yuan. But the water of Yangtze river is not yet flowed to Beijing and is reserved and used by cities along the way. The state plans to build a million tons per day reverse osmosis seawater desalination plant in Tianjin, and the reverse osmosis fresh water is sent to Beijing by a pipeline. Tianjin is at Bohai Bay, the lowest temperature of seawater in winter is 0 ℃, and the method is not suitable for reverse osmosis seawater desalination. It is very difficult to heat two million tons of 0 ℃ seawater to 20 ℃ every day with industrial waste heat, and coastal zones of Tianjin do not have that much industrial waste heat. An article exists in the reference message of 19 days 6 and 6 months 2017, and american scientists heat carbon nanotubes and then make fresh water contained in seawater with a certain pressure pass through the heated carbon nanotubes to obtain concentrated sodium chloride micro-crystallization seawater. The concentrated seawater generated by the seawater desalination can be directly used for producing salt or used for electrolyzing salt water to produce caustic soda, chlorine and hydrogen. Fifteen days in october to fifteen days in forty-five days in the next year are the heating seasons in cities in the areas north of the Yangtze river, and smoke generated by the coal-fired heating boiler causes haze in the cities in the north.
