DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0046] FIG. 1 shows an outer view of an embodiment of a deionization device 1 according to the invention, and FIG. 2 discloses a corresponding inner view of the deionization device 1. This has a first chamber 2 for an ion exchange agent, which has a first intake opening 3 and a first discharge opening 4. The first chamber 2 is in the form of a column, and disposed concentrically in a second chamber 5 for a second ion exchange agent. The second chamber is likewise in the form of a column, and has a second intake opening 6 and a second discharge opening 7.

[0047] As shown in FIG. 3, the first chamber and the second chamber 5 are connected by a line 8. This line 8 has a third intake opening 9 and a third discharge opening 10. The third intake opening 9 is dedicated to the first discharge opening 4 of the first chamber 2. The third discharge opening 10 is dedicated to the second intake opening 6 in the second chamber 5. In order to deionize a liquid, it is first introduced into the first chamber through the first intake opening 3. A first step of the deionization can take place there through a first ion exchange agent, e.g. a cation exchange resin. The liquid can then exit the first chamber 2 though the first discharge opening 4. The liquid can be removed via the third intake opening 9 in the line 8. The liquid exits the line 8 forming an overflow line through the third discharge opening 10, and then enters the second chamber 5 through the second intake opening 6. The liquid can be deionized in a second step in the second chamber 5 through a further ion exchange agent, e.g. an anion exchange resin. The deionized liquid than then be removed for further use through the second discharge opening 7 in the second chamber 5.

[0048] As FIG. 4 shows, the line 8 also has a first regeneration opening 11 for a first regeneration liquid, and a second regeneration opening 12 for a second regeneration liquid. In order to prevent leakage of the liquid that is to be deionized, closures 13 are disposed in the first regeneration opening 11 and the second regeneration opening 12. These closures 13 are formed as stoppers 14, as shown in FIG. 5.

[0049] FIG. 5 shows that the deionization device 1 according to the invention has an encompassing housing 17 with a housing lid 18, as also shown in FIGS. 1 to 4. The line 8 is disposed in this housing lid 18, as also shown in FIGS. 3 and 4. The first regeneration opening 11 and the second regeneration opening 12 in the line 8 open into the housing lid 18. The housing lid 18 has a recess 19 in the region of the openings. A cover plate for covering the first regeneration opening 11 and the second regeneration opening 12, as well as the stoppers placed thereon, can be disposed in the recess 19. The housing lid 18 also has a lid intake opening 20, for conducting a liquid into the deionization device 1, as shown in FIG. 1. The lid intake opening 20 opens into a lid intake line 21, which leads to the first intake opening 3 in the first chamber 2. In order to remove the deionized liquid, the housing lid 18 has a lid discharge opening 22, dedicated to the second discharge opening 8 in the second chamber 5, as shown in FIG. 1.

[0050] As shown in FIG. 6, a connection adapter 15 is disposed in the first regeneration opening 11 and the second regeneration opening 12 in the line 8 for introducing and/or removing a first and second regeneration liquid instead of the stoppers 14, for regenerating the deionization device 1 according to the invention. The connection adapter 15 has two tube-shaped stopper sections 16, specifically a first tube-shaped stopper section 16.1 and a second tube-shaped stopper section 16.2. The first regeneration opening 11 and third intake opening 9 are flush with one another. The first tube-shaped stopper section 16.1 has a design corresponding to the aforementioned openings. Furthermore, the second tube-shaped stopper section 16.2 is disposed in the regeneration opening 12 and the third discharge opening 10. The second regeneration opening 12 and the third discharge opening 10 are likewise flush with one another. The second tube-shaped stopper 16.2 extends from the second regeneration opening 12 to the third discharge opening 10, and is designed in a manner corresponding to this opening. The first regeneration opening 11 and the third intake opening 9 are isolated by the connection adapter 15 from the second regeneration opening 12 and the third discharge opening 10 for a regeneration of the deionization device.

[0051] For a regeneration of the assembly shown in FIG. 6, the respective regeneration liquid is added to and removed from the chamber 2 and 5 in a direction counter to the flow. A first regeneration liquid is introduced accordingly into the first chamber 2 through the first tube-shaped stopper section 16.1 through the first discharge opening 4, and removed from the first chamber 2, or the deionization device 1, respectively, via the first intake opening 2, the lid intake line 21, and the lid intake opening 20, see FIG. 1. Furthermore, a second regeneration liquid is introduced into the second chamber 5 via the lid discharge opening 22 and the second discharge opening 7, and removed from the second chamber 5, or the deionization device 1, respectively, via the second intake opening 6 and the second tube-shaped stopper section 16.2.

[0052] The first intake opening 3 of the first chamber 2 and the second intake opening 6 of the second chamber each open into a gravity pipe 23, see FIGS. 2, 4 and 5. These gravity pipes 23 extend from the housing lid 18 to a base of the housing 17, not shown. Inserts 24 are disposed on the housing lid 18, which are dedicated to the respective discharge openings 4, 6 in the chambers 2, 5. The housing 17 also has wheels 25, as well as handles. 26.

[0053] FIG. 6 also shows that the two tube-shaped stopper sections 16.1, 16.2 have projections 27. The two tube-shaped stopper sections 16.1, 16.2 of the connection adapter 16 are secured to the housing lid 18 by a retention plate 28, which is screwed into the holes 19 in the housing lid 18, and bears on the projections 27. The two tube-shaped stopper sections 16.1, 16.2 also have seals 29. The stoppers 14 also have seals of this type 29, see FIG. 4.
