Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.
[0028] The solution regenerator of the present application can complete two-stage filtration of the solution by using the first filter chamber and the second filter chamber arranged up and down, utilizing the gravity of the solution and the different filtering directions of the filter chambers, and can perform rotational flushing of the filter chamber by means of a rotating spray assembly.
[0029] See also Figure 1-3 The solution regenerator of the embodiment of the present application includes an outer cylinder 21, which is cylindrical and has closed upper and lower ends; a first filter chamber 1, which is a chamber for primary filtration and is located inside the outer cylinder 21; a second filter chamber 10, which is arranged below the first filter chamber 1 and is used for secondary filtration; a transition chamber 5, which surrounds the first filter chamber 1 and the second filter chamber 10 and is used to temporarily accommodate the solution flowing out of the first filter chamber 1; and a funnel 8, which is connected to the lower end of the outer cylinder 21.
