Description

Technical Field

[0001] This utility model relates to the technical field of reverse osmosis wastewater recovery, and in particular to a reverse osmosis wastewater recovery device. Background Technology

[0002] Reverse osmosis, also known as reverse osmosis, is a membrane separation process that uses pressure difference as the driving force to separate the solvent from the solution. Pressure is applied to the feed solution on one side of the membrane. When the pressure exceeds its osmotic pressure, the solvent will permeate in the opposite direction of natural osmosis. Thus, the permeated solvent, i.e., permeate, is obtained on the low-pressure side of the membrane, while the concentrated solution, i.e., concentrate, is obtained on the high-pressure side. If reverse osmosis is used to treat wastewater, pure water can be obtained on the low-pressure side of the membrane. Therefore, reverse osmosis wastewater recovery units are particularly needed.

[0003] However, existing reverse osmosis wastewater recovery units, due to frequent and prolonged use, will accumulate a certain amount of chemical dirt inside. Cleaning requires complete disassembly, which is quite troublesome and affects the time it takes for wastewater to permeate into pure water. Utility Model Content

[0029] Working principle: First, the outer shell 402 is fixed to the steel frame 1 by clamp 401. When sewage enters the inner shell 402 from the conveying pipe 3, it permeates inward through the permeation membrane 403, then to the first filter screen 404 for impurity filtration, then to the first cotton layer 405 for chemical filtration, then to the second filter screen 406, the second cotton layer 407, and the third filter screen 408 for filtration in sequence, and finally to pure water through the deep filtration of solid cotton 409. The pure water then flows into the collection tank 8 through the pure water pipe 7. When it is necessary to clean the solid cotton 409 and the inner side of the outer shell 402, the motor 601 is started, which drives the filter element 604 and the external brush 605 to rotate for internal cleaning. Water is sprayed outward through the water outlet 606 on the outside of the central water collection pipe 602 to clean the inner wall. The sealing gasket 603 can seal the inner wall.
