Description

Technical Field

[0001] The invention belongs to the technical field of mechanical engineering and relates to a balanced flow water distribution device for a mixed ion exchanger. Background Art

[0002] In the condensate polishing system, the high-speed mixed bed operates in a top-down co-current filtration and desalination mode. The condensate pump disperses the condensate from the top water distribution plate into the high-speed mixed bed body. After passing through the anion-cation mixed resin layer, the mixed resin layer removes ions in the water to achieve the purpose of desalination and water purification. In the prior art, since the top water distribution plate cannot evenly distribute the condensate from the condensate pump through the water caps connected to the water distribution plate, and at the same time, due to the very strong fluidity of the anion-cation exchange resin mixed resin layer in the high-speed mixed bed body, the resin in the mixed bed body often shows a phenomenon of uneven flow. When the uneven flow is serious, it will cause a significant reduction in the water production cycle of the mixed bed, an increase in the number of regenerations, an increase in the consumption of acid and alkali, an increase in the waste water discharge, and an increase in the consumption of demineralized water, increasing the operation and maintenance burden of the operators and affecting the economy, energy conservation and environmental protection effects of the unit. Summary of the Invention

[0003] The purpose of the invention is to overcome the above-mentioned disadvantages of the prior art and provide a balanced flow water distribution device for a mixed ion exchanger, which can effectively solve the problem of uneven flow of resin in the mixed bed body.

[0004] To achieve the above purpose, the balanced flow water distribution device for the mixed ion exchanger of the invention includes a high-speed mixed bed, an alloy water distribution plate connection frame and a number of balanced flow water caps;

[0005] The bottom of the high-speed mixed bed is fixed on the alloy water distribution plate connection frame. A number of reserved holes are provided on the alloy water distribution plate connection frame. Among them, one reserved hole corresponds to one balanced flow water cap. The balanced flow water cap includes a uniform flow inlet chamber, a balanced flow valve chamber and a water distribution water cap that are connected in sequence from top to bottom. The top of the uniform flow inlet chamber is closed, and the bottom of the water distribution water cap is closed. A number of water inlet channels are provided on the side wall of the uniform flow inlet chamber. A number of opening gaps are provided on the side of the water distribution water cap. The size of the opening gap is larger than the diameter of the mixed ion resin in the high-speed mixed bed, and the balanced flow valve chamber is fixed in the reserved hole.

[0006] Each water inlet channel is evenly distributed on the side wall of the uniform flow inlet chamber.

[0007] Each opening gap is evenly distributed along the circumference.

[0008] The opening gap is of a rectangular structure.

[0009] The bottom of the high-speed mixed bed is fixed to the alloy water distribution plate connection frame by bolts.

[0010] A pressure element is arranged in the balanced flow valve chamber.

[0011] It further includes a resin flushing water pipe for flushing the resin in the high-speed mixed bed, and the resin flushing water pipe is connected to the alloy water distribution plate connection frame.

[0012] Each reserved hole is evenly distributed.

[0013] The present invention has the following beneficial effects:

[0014] When the balanced flow water distributor of the mixed ion exchanger described in the present invention is in specific operation, the balanced flow water cap includes a uniform flow water inlet chamber, a balanced flow valve chamber and a water distribution water cap that are connected in series from top to bottom. Among them, the top of the uniform flow water inlet chamber is closed, the bottom of the water distribution water cap is closed, several water inlet channels are arranged on the side wall of the uniform flow water inlet chamber, and several opening gaps are arranged on the side of the water distribution water cap, so that the condensate incoming water will not directly impact the balanced flow valve chamber in a large flow rate, thus causing the phenomenon of uneven flow when multiple balanced flow water caps are used at the same time, effectively solving the uneven flow phenomenon of the resin in the mixed bed body, with simple structure, convenient operation and strong practicability.
