Description

Technical Field

[0001] The utility model relates to the field of water treatment ion exchange equipment, in particular to an ion exchange column. Background Art

[0002] In fields such as water treatment, ion exchange columns are a commonly used water purification device. When manned space crews remain in orbit for long periods of time, wastewater such as urine and condensate needs to be regenerated and treated, which also requires the use of ion exchange columns. Unlike ground-based use, ion exchange resins are difficult to regenerate and reuse in orbit. Once the ion exchange resin breaks through, the ion exchange column becomes discarded. The high cost of manned space launch products requires high ion exchange resin utilization. However, wastewater such as urine and condensate contains a large amount of weak acids, which have a slow exchange rate and can easily lead to resin degradation. Furthermore, due to the limited space dimensions in orbit, the height-to-diameter ratio of the ion exchange column should not be too large. All of these factors hinder the improvement of ion exchange resin utilization.

[0003] Therefore, how to improve the utilization rate of ion exchange resin while reducing the volume of ion exchange column is an urgent problem to be solved in the field of water treatment. Utility Model Content

[0035] In order to better understand the present invention, the contents of the present invention are further described below in conjunction with the accompanying drawings.

[0036] like Figure 1 As shown, a high-efficiency ion exchange column comprises:

[0037] Exchange column housing 102;

[0038] A support rod 103 is provided at the axis of the exchange column housing 102;

[0039] A first spiral blade 101 is spirally fixed to a support rod 103, and an outer edge of the first spiral blade 101 is sealed to the exchange column housing 102;

[0040] The second spiral blade 104 is spirally fixed to the support rod 103 and spaced apart from the first spiral blade 101. The outer edge of the second spiral blade 104 is sealed with the exchange column shell 102.

[0041] The first spiral blade 101 and the second spiral blade 104 divide the internal space of the exchange column shell 102 into a first cavity 8 and a second cavity 9, and the first cavity 8 and the second cavity 9 are connected at the bottom of the exchange column shell 102;

[0042] An end cap 5 is provided on the top of the exchange column housing 1;

[0043] A first pipeline interface is provided through the end cover 5 and communicates with the first cavity 8;

[0044] A second pipeline interface is provided through the end cover 5 and communicates with the second cavity 9;

[0045] The first cavity 8 and the second cavity 9 are used to be filled with resin material.

[0046] In the present invention, by dividing the exchange column shell 1 into two cavities, namely the first cavity 8 and the second cavity 9, the effective length of the ion exchange column is multiplied. At the same time, the structure is more compact and the aspect ratio is low, which improves the utilization rate of the resin in the exchange column and meets the requirements of manned space missions for compact structure.

[0047] The design of the first spiral blade 101 and the second spiral blade 102 enables the working medium to flow in a spiral curve in the exchange column, further increasing the effective length of the exchange column and further improving the utilization rate of the resin in the ion exchange column.

[0048] The end cover 5 is arranged on the top of the exchange column shell 1.

[0049] In water treatment, the end cap 5 can prevent pollutants such as dust, microorganisms and other impurities from flowing into the column; the end cap 5 is connected to the exchange column housing 1 by screws and sealed with a sealing gasket 4.

[0050] A high-efficiency ion exchange column, further comprising:

[0051] The filter assembly 2 is arranged on the upper part of the first cavity 8 and the second cavity 9;

[0052] In the present invention, the filter assembly 2 is provided at the upper portion of the cavity to prevent the resin and debris in the first cavity 8 and the second cavity 9 from flowing out.

[0053] A compression spring 3 is provided between the filter assembly 2 and the end cover 5. After the exchange column housing 1 is printed out by 3D one-piece molding, the support rod 103 is installed to obtain the first cavity 8 and the second cavity 9. Subsequently, the first cavity 8 and the second cavity 9 are filled with resin material, the filter assembly 2 is installed, and then the compression spring 3 and the end cover 5 are installed. After filling, the compression spring 3 has a certain compression force. The compressed spring can generate elastic force. When manned spacecraft is in orbit, the elastic force can absorb the energy generated by impact or vibration and reduce damage to other components. Secondly, the elastic force can also be used to maintain the position of mechanical components and provide restoring force when the components are subjected to external forces.

[0054] The end cover 5 is provided with a first pipeline interface corresponding to the first cavity 8, and the inlet quick connector 6 is connected to the exchange column housing 1 through the first pipeline interface. The inlet quick connector 6 is inserted into the first pipeline interface of the end cover 5 and fixed by screws.

[0055] The inlet quick-connect connector 6 is connected to the input pipeline of the external working fluid, and the outlet quick-connect connector 7 is connected to the output pipeline of the external working fluid. The inlet quick-connect connector 6 and the outlet quick-connect connector 7 are installed on the same side of the product.

[0056] The end cover 5 is provided with a second pipeline interface corresponding to the second cavity 9, and the outlet quick connector 7 is connected to the exchange column housing 1 through the second pipeline interface. The outlet quick connector 7 is inserted into the second pipeline interface of the end cover 5 and fixed by screws.

[0057] like Figure 2 As shown, the first cavity 8 is connected to the second cavity 9 at the side away from the end cover 5.

[0058] The working fluid flows from the inlet quick-connector 6 through the first spiral blade 101 within the first cavity 8, reaches the bottom of the first cavity 8, flows into the second cavity 9 at the connection point between the first cavity 8 and the second cavity 9, and then flows out of the outlet quick-connector 7 along the second spiral blade 102. The long flow distance of the working fluid provides ample time for the ionic contaminants in the working fluid to undergo an exchange reaction with the resin, thereby improving the utilization rate of the ion exchange resin.

[0059] An annular groove for accommodating the compression spring 3 is provided on the end cover 5 .

[0060] The annular groove evenly distributes the pressure of the compression spring 3 on the filter membrane 202, ensuring the consistency of the filtering effect.

[0061] like Figure 3 As shown, the filter assembly 2 includes:

[0062] A filter membrane support 201 , a filter membrane pressing plate 203 arranged on the filter membrane support 201 , and a filter membrane 202 covering the filter membrane pressing plate 203 .

[0063] The filter assembly 2 improves the filtering effect through the coordinated use of the filter membrane bracket 201 and the filter membrane pressure plate 203. At the same time, the filter membrane bracket 201 provides stable support for the filter membrane 202, ensuring stability and consistency during the filtration process. The annular protrusion on the filter membrane bracket 201 can prevent the spring from deflecting.

[0064] In one possible implementation of the present invention, the working fluid enters the first cavity 8 through the inlet quick-connect fitting 6, flows through the resin in the first cavity 8 via the first spiral blade 101, and purifies the working fluid. After reaching the bottom of the first cavity 8, the working fluid flows into the second cavity 9 at the connection point between the first cavity 8 and the second cavity 9. An electric pump provides pressure to the working fluid, causing it to flow from bottom to top along the second spiral blade 104 at the bottom of the second cavity 9. The working fluid is further purified by the resin in the second cavity 9, and the purified working fluid flows out through the outlet quick-connect fitting 7. This multiplies the effective length of the ion exchange column, helping to improve the utilization rate of the mitigation value.
