Description
Technical Field
[0001] The utility model relates to the technical field of nanofiltration devices, in particular to a nanofiltration device with a nanofiltration high-pressure pump. Background Art
[0002] Nanofiltration device is a pressure-driven membrane separation device between reverse osmosis and ultrafiltration. Most nanofiltration membranes are evolved from reverse osmosis membranes, but compared with reverse osmosis, the operating pressure of nanofiltration devices is lower. Therefore, nanofiltration equipment is also called low-pressure reverse osmosis or loose reverse osmosis. Because inorganic salts can dialyze through nanofiltration membranes, the osmotic pressure of nanofiltration is much lower than that of reverse osmosis. In this way, under the premise of ensuring a certain membrane flux, the external pressure required for the nanofiltration process is much lower than that of reverse osmosis. The existing nanofiltration devices have certain disadvantages when used. The external pressure required for the nanofiltration process is small, and if the external pressure is large, there can be better osmotic flux and better osmosis effect. Usually, there is no pressurized structure in the nanofiltration device, so the osmotic flux is insufficient. After long-term use, the nanofiltration membrane needs to be disassembled and cleaned, and the nanofiltration membrane is located inside the nanofiltration tube. The nanofiltration tube must be disassembled before the nanofiltration membrane can be disassembled, and the operation is cumbersome. For this reason, we propose a nanofiltration device with a nanofiltration high-pressure pump. Utility Model Content
