Introduction to Caofeidian port seawater desalination project
Caofeidian port, also known as “shaleidian”, is the Caofeidian port area of Tangshan port. It is located in the oldest area in the west of Sanzhou of Luanhe River. It is a small island where ancient fishermen took shelter from the wind. It was formed about 5500 years ago.
Caofeidian is adjacent to the Beijing Tianjin Hebei Urban Agglomeration. Caofeidian is 400 nautical miles away from Incheon, South Korea, 680 nautical miles away from Nagasaki and 935 nautical miles away from Kobe, Japan. The sea route with the ore exporting countries such as Australia, Brazil, Peru, South Africa and India is also very smooth.
In 2012, the cargo throughput of Caofeidian port area was 195 million tons. Driven by Caofeidian port area, Tangshan port ranked the tenth in the world with a cargo throughput of 364 million tons, with an increase of 16.8%, ranking the first among the top ten ports in the world.
In 2017, the cargo throughput of Caofeidian port area was 283 million tons.
Seawater desalination is to use seawater desalination to produce fresh water. It is an open-source incremental technology to realize the utilization of water resources. It can increase the total amount of fresh water without being affected by time, space and climate. It can ensure the stable supply of drinking water for coastal residents and industrial boiler water.
The process of obtaining fresh water from seawater is called seawater desalination. At present, the seawater desalination methods used include seawater freezing method, electrodialysis method, distillation method, reverse osmosis method and ammonium carbonate ion exchange method. At present, the reverse osmosis membrane method and distillation method are the mainstream in the market.
There are more than 100 scientific research institutions in more than 10 countries in the world conducting research on seawater desalination, and hundreds of seawater desalination facilities with different structures and capacities are working. A modern large-scale seawater desalination plant can produce thousands, tens of thousands or even nearly one million tons of fresh water every day. The cost of water is constantly decreasing. In some countries, it has been reduced to the price of tap water. The desalination water in some areas has reached the national and urban water supply scale.

Rubber joint are also called rubber pipe soft joints, flexible rubber joints, rubber soft joints, flexible rubber joints, high-pressure rubber joints, rubber shock absorbers, compensators, etc. According to the connection mode, it is divided into loose flange type, fixed flange type and threaded type; According to the structure, it can be divided into five kinds: single sphere, double sphere, reducer, curved sphere and wind pressure coil. The tubular rubber part is composed of inner and outer rubber layers, cord fabric layers and steel rings, which is vulcanized and formed, and then combined with the loose sleeve of metal flange or parallel joint. This product can reduce vibration and noise, and can compensate the thermal expansion and cold contraction caused by temperature change. It is widely used in various pipeline systems.
