Shanghai Luoying supplies pipe transmission joint for seawater desalination industrialization project


East China University of science and technology, Shougang Group, etc. have undertaken the large and medium-sized seawater desalination industrialization technology R & D and application. The 50000 T / D hydropower cogeneration and hot film coupling R & D and demonstration research were launched in Beijing a few days ago.
Due to the limitations of the existing technology, a large number of concentrated brine produced in the process of seawater desalination can not be further utilized, which not only wastes valuable marine resources, but also may cause new environmental pollution, especially the impact on the ecological environment of the semi closed sea area around the Bohai Sea. East China University of science and technology Salt Lake Center Director Yu Jianguo said.
It is understood that in the project, the Salt Lake Center will be responsible for the comprehensive utilization technology research and engineering demonstration construction of seawater desalination and concentrated brine. The center will adopt the comprehensive process of chemical method and membrane method to efficiently separate calcium, magnesium and other key hardness elements in concentrated seawater to prepare high value-added inorganic functional materials; through secondary desalination, the recovery rate of fresh water will be greatly improved, and the seawater will be deeply concentrated to prepare liquid salt raw materials for the pure alkali industry; through pilot research and technology integration, a series of fresh water, liquid salt and magnesium based products will be formed (industrial magnesium hydroxide, flame retardant magnesium hydroxide, magnesium carbonate, hydrotalcite, etc.), bromine, calcium carbonate and other valuable elements are integrated utilization system to achieve zero emission.
For the whole project construction, Shanghai Luoying's double flange limited force transfer joint plays a very important role. The double flange force transfer joint installed on the pipeline line can transmit the vibration near the source to the whole pipeline, so as to achieve the effect of balancing the axial thrust, and further ensure the normal operation of the pipeline. Shanghai Luoying as a professional force transfer joint manufacturer, product quality can stand the test of practice. Tel: 021-6221 2627
