| titleOfInvention | Multi-stage filter cartridges for ultrapure water preparation |
| abstract | The utility model discloses a multi-stage filter core for ultrapure water preparation, relates to the technical field of ultrapure water preparation, and solves the problem that the existing ultrapure water preparation in the prior art needs to undergo multiple steps of filtration, In this way, it is necessary to apply multiple sets of filter elements to match. This multi-stage filtration method has a long cycle time and low preparation efficiency. The multi-stage pure water filter element includes a mesh shell layer, an inner bile duct layer and a reverse osmosis membrane tube, the reverse osmosis membrane tube is arranged inside the inner bile duct layer, and the mesh surface shell layer is arranged outside the inner bile duct layer, so A first-stage separation filter cavity is set between the mesh surface shell layer and the inner bile duct layer, and a second-level separation filter cavity is set between the inner bile duct layer and the reverse osmosis membrane tube, and sealing rings are arranged at both ends of the reverse osmosis membrane tube buckle, and the reverse osmosis membrane tube is combined with the sealing ring buckle, the inside of the mesh surface shell layer is provided with PP cotton and activated carbon particles, and the inside of the inner tube layer is provided with compressed activated carbon. |
