Description

Technical Field

[0001] The utility model relates to the technical field of reverse osmosis membrane detection, in particular to a reverse osmosis membrane pollution degree detection device. Background Art

[0002] The reverse osmosis membrane pollution degree detection device is a device used to detect the membrane pollution degree in the reverse osmosis system. The reverse osmosis system is a water treatment technology that separates impurities and pollutants in water through a semi-permeable membrane to obtain pure water. However, during the reverse osmosis process, pollutants are easily accumulated on the membrane surface, resulting in a decrease in the filtering effect of the membrane and affecting the water treatment effect. Therefore, regular detection of the pollution degree of the reverse osmosis membrane is crucial to maintaining the normal operation of the system. The reverse osmosis membrane pollution degree detection device is usually composed of sensors, data acquisition devices and display screens. The sensors can detect parameters such as pressure difference, flow rate, conductivity on both sides of the membrane, and transmit these parameters to the display screen through the data acquisition device. Users can intuitively understand the pollution degree of the reverse osmosis membrane through the display screen. In short, the reverse osmosis membrane pollution degree detection device can help users detect the pollution degree of the reverse osmosis membrane, take cleaning or replacement measures in time, ensure the normal operation of the reverse osmosis system, and improve the water treatment effect.

[0003] According to the retrieval of China Invention Publication No.: CN116585893A, a detection device for efficiently disassembling and assembling a reverse osmosis membrane is disclosed. The reverse osmosis membrane to be detected can be placed on a first fixed seat and a second fixed seat, and the driving unit is used to make the movable plates at both ends of the reverse osmosis membrane move synchronously, so that the two ends of the reverse osmosis membrane can be quickly connected. At the same time, the sealing structure can increase the sealing of the connection, and the detection unit can be used to detect the connected reverse osmosis membrane. The operation is simple, and the reverse osmosis membrane to be detected can be quickly connected and disassembled, thereby improving the detection efficiency.

[0004] However, there are some issues that need to be considered when implementing the above technical solution: first, the device clamps and fixes the outside of the reverse osmosis membrane and then connects it to the pipeline, which cannot adapt to reverse osmosis membranes of different specifications; second, the device needs to be connected to multiple pipelines, which complicates the operation and reduces the detection efficiency.
