Description

Technical Field

[0001] This utility model relates to the field of purification columns, and more particularly to a reverse-chip purification column. Background Technology

[0002] Existing dual-column purification systems generally employ an inlet and outlet design with the top and bottom ends arranged on the same side. The first purification column uses a top-down water flow direction, with fluid pressure fixing the mixed resin, including anion and cation resins, to the bottom of the column. However, when water enters the second purification column, the direction reverses to bottom-up, causing the resin to remain suspended due to the upward fluid force. Since the density of anion resin is significantly higher than that of cation resin, during long-term start-stop cycles, the combined effect of fluid dynamics and gravity causes reverse stratification of the resin layer—high-density anion resin gradually sinks, while low-density cation resin floats. This dynamic separation phenomenon significantly reduces resin mixing efficiency, causing an unexpected acidic shift in the effluent pH, severely impacting the water quality stability of the ultrapure water system. Utility Model Content

[0003] The purpose of this invention is to address the problem of water quality stability in the prior art by proposing an inverted purification column.

[0004] An inverted purification column consists of a purification column body, a purification column top cover, and a purification column bottom cover, with an inlet and an outlet respectively provided on the bottom cover.

[0005] Furthermore, an inverted purification column is provided, wherein the top cap and bottom cap of the purification column are both connected to the purification column body by welding.

[0006] Furthermore, an inverted purification column is provided, wherein filter screens are provided at both ends of the purification column body.

[0007] Furthermore, an inverted purification column is provided, wherein the purification column body comprises a first purification column body and a second purification column body.

[0008] Furthermore, in an inverted purification column, the first purification column body and the second purification column body are fixed by a rubber ring on a filter screen.

[0009] Furthermore, in an inverted purification column, the inlet is located at the lower end of the first purification column body, and the outlet is located at the lower end of the second purification column body.

[0010] Furthermore, an inverted purification column is provided with a connection port at the bottom of the top cap.

[0011] Furthermore, an inverted purification column is provided, wherein the connection port is located between the first purification column body and the second purification column body.

[0012] The beneficial effects of this utility model are as follows: With an inverted purification column, the inlet is set at the lower end of the first purification column body and the outlet is set at the lower end of the second purification column body. When the water flows into the first purification column body, it flows from bottom to top. When the water flows through the first purification column body, it flows from top to bottom. The resin is fixed by the downward force of the water flow, maintaining the original state of uniform mixing of anion and cation resins, thereby ensuring that the produced water is slightly neutral.

[0016] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0017] As attached Figures 1-2 As shown, the composition and structure of a flip-chip purification column are as follows:

[0018] An inverted purification column is composed of a purification column body 1, a purification column top cover 2, and a purification column bottom cover 3. The purification column bottom cover 3 is provided with an inlet 4 and an outlet 5.

[0019] Furthermore, in an inverted purification column, the top cap 2 and the bottom cap 3 of the purification column are both connected to the purification column body 1 by welding.

[0020] Furthermore, an inverted purification column is provided, wherein filter screens are provided at both ends of the purification column body 1.

[0021] Furthermore, an inverted purification column, wherein the purification column body 1 includes a first purification column body 11 and a second purification column body 12.

[0022] Furthermore, in an inverted purification column, the first purification column body 11 and the second purification column body 12 are fixed by a rubber ring on a filter screen.

[0023] Furthermore, an inverted purification column is provided with a connection port at the bottom of the top cap 2 of the purification column.

[0024] Furthermore, an inverted purification column is provided, wherein the connection port is located between the first purification column body 11 and the second purification column body 12.

[0025] Furthermore, in an inverted purification column, the inlet 4 is located at the lower end of the first purification column body 11, and the outlet 5 is located at the lower end of the second purification column body 12.

[0026] As attached Figure 2 As shown, the implementation principle of a flip-chip purification column is as follows:

[0027] As shown by the arrow, the water flows from the inlet 4 into the first purification column 11 from bottom to top, and then flows through the connection port to the second purification column 12. When the water flows through the second purification column 12, the water flows from top to bottom. The finely mixed resin is fixed by the downward force of the water flow. The finely mixed resin still maintains the original state of uniform mixing of the anion and cation resins to ensure that the produced water is slightly neutral. Finally, the water is discharged through the outlet 5.
