Description
Technical Field
The utility model relates to a receive and strain concentrator technical field, especially relate to the integrative equipment of reverse osmosis is received in the concentration of polyphenol.
Background
Early in the eighties, scientists studied a thin film composite membrane that dialyzed 90% NaCl and retained 99% sucrose. Obviously, this membrane separation technique is neither known as a reverse osmosis membrane nor in the category of ultrafiltration membranes (because of the inability to dialyze low molecular weight organics). Since the retention rate of the membrane in the permeation process is greater than 95% of molecules about 1 nm, the membrane is named as a 'nanofiltration membrane'. The cut-off molecular weight of the nanofiltration membrane is from 200-1000, so that more than 90 percent of NaCl can be dialyzed, and the method is suitable for various processes such as desalination, monosaccharide removal, concentration equipment and the like.
Compared with reverse osmosis, the membrane structure is mostly a multi-layer loose structure, and has higher permeation flux even under the conditions of high salinity and low pressure because inorganic salt can pass through the nanofiltration membrane to dialyze, so that the permeation pressure of nanofiltration is far lower than that of reverse osmosis, and the external pressure required by the nanofiltration process is much lower than that of reverse osmosis on the premise of ensuring certain membrane flux. And under the same pressure, the membrane flux of the nanofiltration is much larger than that of the reverse osmosis. In addition, nanofiltration can lead the special concentration and separation equipment and the desalination process to be carried out synchronously, so that the nanofiltration replaces the reverse osmosis, the concentration process can be effectively and rapidly carried out, and the concentration multiple is larger. The nanofiltration membrane can be used for desalting and concentrating at the same time, and has the characteristics of high treatment speed, no damage at normal temperature, low cost and high yield when used for concentrating antibiotics and synthetic drugs.
Most of the existing polyphenol concentration nanofiltration reverse osmosis equipment have complex structures, large occupied area and poor filtering effect, can not be unattended and can also work in a full-automatic manner, and simultaneously the inside of a tubular membrane is easy to cause blockage.
