Publication number: 20240083780Abstract: A method and a system for saline-alkali water treatment by multi-membrane nanofiltration and photothermal conversion are provided. The method includes the following steps: separating Na+ contained water from saline-alkali water by multi-membrane nanofiltration; discharging the obtained Na+ contained water into an evaporation zone, and evaporating in grid-shaped pools step by step by sunlight. A membrane separation method is used with nanomembrane as the core to separate monovalent ion water from high-valent ion water, thus separating Na+ contained water from K+ contained water by NF, and finally extracting fresh water from Na+ contained water by a NF-RO component; meanwhile, a fertilizer preparation method can be used to handle high-valent ion water, K+ contained water and fresh water to obtain a liquid fertilizer or a soil conditioner; a KCl drug extraction method is used to treat K+ contained water in step S1 to obtain a potassium-supplementing drug stock solution.Type: ApplicationFiled: September 8, 2023Publication date: March 14, 2024Inventors: Zhilin SUN, Yizhi SUN, Yunze SHEN

Patent number: 11542141Abstract: A funnel based on bivariate normal distribution is provided, and belongs to the field of daily tools. The funnel is formed by connecting a funnel body in a shape of a bivariate normal distribution with an outlet tube. The funnel body can be formed by rotating a normal distribution curve around the axis of symmetry z with a positive direction pointing to a deep part of the funnel, towards which the fluid flows. An outlet tube is a conical structure with a wide upper part and a narrow lower part. The surface of the funnel body has arbitrary order smoothness at everywhere. The design is simple and the fluid experiences little resistance when it flows through the inner surface. Thus, the funnel can effectively prevented blockage during the transport of fluid, powder and granules and the transport efficiency is remarkably improved.Type: GrantFiled: December 20, 2021Date of Patent: January 3, 2023Inventors: Yizhi Sun, Zhilin Sun, Haolei Zheng, Chunhong Hu
