[0032] The sodium chloride solution inlet pipe 3 is installed to the upper end of the other side of the alkali removing pool 1, and is used for introducing the sodium chloride solution to be treated. The sodium chloride solution discharge pipe 8 is formed in the upper end of the outside of the side secondary sedimentation tank 5, and is used for discharging the treated sodium chloride solution.

[0033] ​In order to ensure the processing process, the sodium chloride solution inlet pipe 3 is installed higher than the overflow opening 4, and the overflow opening 4 is installed higher than the sodium chloride solution outlet pipe 8.

[0034] (2) The medicament feeding system, as shown in Figure 1 、 Figure 3 、 Figure 4 and Figure 5 :

[0035] The upper fixed support 12 is centrally installed with a medicament feeding tank 13 at the upper end. The medicament feeding tank 13 is installed with a medicament distribution pipe 15 at the lower end through a pipeline. The C-shaped medicament outlet pipe 16 is arranged at the middle and both sides of the inside of the alkali removal tank 1 along the lower end of the upper fixed support 12. The medicament distribution pipe 15 is in communication with the inside of the C-shaped medicament outlet pipe 16, which is used to uniformly feed the medicament into the alkali removal tank 2. The upper end of the rear end of the medicament feeding tank 13 is installed with a medicament supplement pipe 14, which is convenient for supplementing the medicament at any time.

[0036] (3) The medicament stirring system, as shown in Figure 1 、 Figure 4 、 Figure 5 and Figure 6 :

[0037] The upper end of the upper fixed support 12 is installed with a conveying pump 17 at the front end. The conveying pump 17 introduces water through a water inlet pipe 18, which can be the sodium chloride solution to be removed alkali. The output end of the conveying pump 17 is connected with a water outlet pipe 19, and the other end of the water outlet pipe 19 is connected with three water distribution pipes 20, which are used to uniformly distribute the solution to different positions in the alkali removal tank 2.

[0038] The middle and both sides of the lower end of the inside of the alkali removal tank 1 are provided with water stirring units 21. Each water stirring unit 21 comprises a rotating pipe body 22. The other end of the water distribution pipe 20 extends to the inside of the rotating pipe body 22 through the front wall of the alkali removal tank 1 and is rotatably connected with the rotating pipe body 22.

[0040] In order to ensure that the solution can pass through the water body stirring pipe 27 at a large speed to push the rotating pipe body 22 to rotate, the inner flow cavity 25 is internally fixed with a conical structure in the middle of each end two groups of self-driven assemblies 26 through a support, which is a cross support and does not affect the solution flow; the incoming solution flows outward due to the existence of the conical body, thereby flowing into the straight part 28 of the water body stirring pipe 27, and then flowing out through the inclined part 30. The four self-driven assemblies 26 are driven to rotate by the rotating pipe body 22 due to the pushing force generated by the water flow.

[0041] Each pipeline is provided with a control valve due to solution control, which controls the water body or reagent to enter and discharge, which is not completely shown in the figure.

[0042] Working principle: open the control valve of the sodium chloride solution inlet pipe 3 to make the sodium chloride solution pass through the sodium chloride solution inlet pipe 3 to reach the alkali removal tank 2, then open the control valve at the lower end of the reagent feeding tank 13 to make the chemical reagent pass through the reagent distribution pipe 15 and the C-shaped reagent discharge pipe 16 to be discharged to multiple points in the alkali removal tank 2.

[0043] At the same time, the delivery pump 17 introduces the water body through the water body inlet pipe 18, which can be the sodium chloride solution to be removed alkali, and the solution reaches the water body distribution pipe 20 through the water body discharge pipe 19, and then enters the inner flow cavity 25 of the rotating pipe body 22; when the water flow is discharged through the water body stirring pipe 27, due to the water flow impact and the shape design of the water body stirring pipe 27, the water flow is discharged outward to drive the rotating pipe body 22 to rotate, disturb the water flow around the outlet of the C-shaped reagent discharge pipe 16, and make the chemical reagent diffuse outward, and the rotation of the rotating pipe body 22 will drive the stirring blade 24 to rotate synchronously, agitate the internal water flow, and make the sodium chloride solution and the alkali removal chemical reagent fully mixed.

[0044] With the continuous input of the sodium chloride solution, the upper solution enters the side secondary precipitation tank 5 through the overflow port 4 for secondary precipitation, and then is discharged through the sodium chloride solution discharge pipe 8. After the treatment is completed, the control valves of the first precipitation discharge pipe 9 and the second precipitation discharge pipe 10 are opened, so that part of the water body carries the precipitate to flow out.
