Embodiment 1

[0037] see Figure 1-3 , the present invention provides a technical solution: a reverse osmosis seawater desalination pretreatment device, specifically comprising:

[0038] A treatment box 1 is provided with a rough filter space 2, an adsorption space 3, a fine filter space 4, and a discharge space 5 in sequence in the treatment box 1, and the rough filter space 2 and the fine filter space 4 are both provided with an arc-shaped filter screen 6, and the adsorption An adsorption device 7 is arranged inside the space 3;

[0039] A cleaning device 8, the cleaning device 8 is arranged inside the fine filter space 4, and one side of the cleaning device 8 is closely attached to the curved filter screen 6 inside the fine filter space 4;

[0040] Control space 9, the control space 9 is set at the center position inside the processing box 1, the inner wall of the control space 9 is fixedly connected with a positioning plate 10, both sides of the positioning plate 10 are fixedly connect...

Embodiment 2

[0045] see Figure 1-4 On the basis of Embodiment 1, the present invention provides a technical solution: the cleaning device 8 includes an arc-shaped sliding plate 81, the top of the arc-shaped sliding plate 81 is fixedly connected to the top of the inner wall of the fine filter space 4 through a return spring 82, and the two ends of the arc-shaped sliding plate 81 Both of them are fixedly connected to the limit slide bar 83, and one side of the curved slide plate 81 is fixedly connected with a cleaning brush 84, and a cleaning device 8 is provided. The mesh of the filter screen inside the filter space 4 is small, and the resistance to water is relatively large. When the water pump 11 sends water to the inside of the fine filter space 4, the water pressure on the side of the filter screen on the inner wall of the fine filter space 4 near the cleaning device 8 increases gradually. Push the cleaning brush 84 inside the cleaning device 8 to move upwards. After the fine filtratio...

Embodiment 3

[0047] see Figure 1-5 On the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: the cleaning brush 84 includes a fixed frame 841, the bottom of the inner wall of the fixed frame 841 is fixedly connected with a fixed brush 842, and the inner wall of the fixed frame 841 is located at the bottom of the fixed brush 842. Part of the rotation is connected with a rotating brush 843, and the two ends of the rotating brush 843 run through the fixed frame 841 and are fixedly connected with a rotating gear 844. Adapted to the tooth groove, the rotating gear 844 extends to the inside of the tooth groove and engages with the inner wall of the tooth groove. There are multiple groups of rotating brushes 843 connected by rubber shafts. A cleaning brush 84 is provided, and a rotating brush 843 is arranged inside the cleaning brush 84 , when the cleaning brush 84 moves up and down, it can drive the rotating gear 844 to rotate through the tooth groove i...

Description

technical field [0001] The invention relates to the technical field of seawater desalination, in particular to a reverse osmosis seawater desalination pretreatment device. Background technique [0002] Seawater desalination is the use of seawater desalination to produce fresh water. It is an open-source incremental technology to realize the utilization of water resources. It can increase the total amount of fresh water and is not affected by time, space and climate. It can ensure a stable water supply for coastal residents and industrial boilers. The process of obtaining fresh water is called seawater desalination. Seawater desalination methods currently used include seawater freezing method, electrodialysis method, distillation method, reverse osmosis method, and ammonium carbonate ion exchange method. Currently, reverse osmosis membrane method and distillation method are the most popular in the market. mainstream. At present, the seawater desalination process using revers...
