Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a device for dynamically recovering and reusing reverse osmosis concentrated water. Background Art

[0002] Reverse osmosis, also known as reverse osmosis, is a membrane separation operation that uses pressure difference as the driving force to separate the solvent from the solution. Pressure is applied to the liquid on one side of the membrane. When the pressure exceeds its osmotic pressure, the solvent will reversely penetrate in the opposite direction of natural osmosis, thereby obtaining the permeated solvent, i.e., permeate, on the low-pressure side of the membrane, and a concentrated solution, i.e., brine, on the high-pressure side. Direct discharge of brine with high salt content, which accounts for 25% of the total water volume, will cause a large amount of water resource waste. Therefore, brine is usually recycled with the help of recycling equipment to reduce water resource waste.

[0003] Chinese patent publication number CN218810523U discloses a reverse osmosis concentrated water recycling device, comprising a main body, an evaporation chamber disposed within the main body, an evaporation heating tank disposed within the evaporation chamber, a semicircular baffle welded above the evaporation heating tank, a transmission cavity disposed above the evaporation chamber, a sterilization chamber disposed on one side of the evaporation chamber, a conveying path disposed below the evaporation chamber, a solenoid valve disposed between the conveying path and the evaporation heating tank, a water outlet pipe disposed on one side of the lower end of the evaporation chamber, one end of the water outlet pipe extending through the main body, and an ultraviolet lamp disposed within the sterilization chamber. The reverse osmosis concentrated water recycling device can pre-sterilize the reverse osmosis concentrated water, thereby reducing the content of microorganisms and bacteria in the concentrated water during evaporation, thereby facilitating evaporation. Furthermore, the device can stir the concentrated water by generating opposing vortices, thereby accelerating evaporation and increasing evaporation efficiency.

[0004] However, the above technical solution has the following shortcomings: in the above device, there is a lack of pretreatment measures for the concentrated water before evaporation, and impurities in the concentrated water easily adhere to the pipe walls and container walls. On the one hand, this affects the heat transfer, resulting in a significant reduction in the water treatment efficiency of the system. On the other hand, it blocks the system, requiring frequent shutdowns for maintenance, which is time-consuming and labor-intensive, and has high maintenance costs, affecting the continuity of the system operation.
