Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to an ion exchanger. Background Art

[0002] At present, in the field of chemical technology, one of the important equipment for producing pure water is the ion exchanger. The ion exchanger mainly uses turbine condensate and produces pure water based on the "ion exchange method". During the production process, the cations (metal ions such as calcium, magnesium, copper, sodium, etc.) and anions (non-metal ions such as carbonate, nitrate, sulfate, etc.) generated by the ionization of various inorganic salts in the turbine condensate will undergo a replacement reaction with the hydrogen ions and hydroxide ions on the resin when passing through the anion and cation resin layers set in the ion exchanger, and then be adsorbed by the resin layer. The hydrogen ions and hydroxide ions replaced from the resin combine to form water molecules, thereby removing the inorganic salts in the turbine condensate and achieving the purpose of producing pure water.

[0003] In the prior art, as the ion exchanger continues to operate, the hydrogen ions and hydroxide ions in the resin layer will gradually be consumed and the resin layer will also become ineffective. At this time, the staff needs to pass regeneration liquid into the ion exchanger. The regeneration liquid will react chemically with the resin layer to "regenerate" the resin layer. After the "regeneration" of the resin layer is completed, the staff also needs to pass a large amount of cleaning liquid into the ion exchanger to rinse the regeneration liquid on the surface of the resin layer and the impurities precipitated and attached to the shallow surface of the resin layer during the "regeneration" process, so as to ensure that the pure water produced subsequently has a higher quality.

[0004] However, due to the large size of the ion exchanger, the flow rate and flow velocity of the cleaning liquid are both large. A large amount of cleaning liquid will generate a large impact force between the middle row device located in the ion exchanger, thereby causing the middle row device to deform and damage.

[0026] In order to solve the problem that the middle row device of the ion exchanger in the prior art is easily damaged, the present application provides an ion exchanger.

[0027] like Figures 1 to 3 As shown, the ion exchanger includes a housing 10, a liquid inlet device 20, a liquid discharge device 30 and a buffer structure 40, and the housing 10 has a first mounting hole 11, a second mounting hole 12 and a receiving cavity. The liquid inlet device 20 is installed at the first mounting hole 11, and the liquid outlet 21 of the liquid inlet device 20 is located in the receiving cavity, so as to transport liquid into the receiving cavity. The liquid discharge device 30 is installed at the second mounting hole 12, and at least part of the liquid discharge device 30 is located in the receiving cavity, so as to discharge at least part of the liquid in the receiving cavity to the outside of the housing 10. The buffer structure 40 is arranged in the receiving cavity and has a buffer surface 41, and at least part of the buffer surface 41 is arranged opposite to the liquid outlet 21.

[0028] Applying the technical solution of this embodiment, the shell of the ion exchanger has a first mounting hole 11, a second mounting hole 12 and a accommodating chamber, the liquid inlet device 20 is installed at the first mounting hole 11, the liquid outlet hole 21 of the liquid inlet device 20 is located in the accommodating chamber for conveying liquid into the accommodating chamber, the liquid discharge device 30 is installed at the second mounting hole, at least part of the liquid discharge device 30 is located in the accommodating chamber for discharging at least part of the liquid in the accommodating chamber to the outside of the shell 10, and the buffer structure 40 is arranged in the accommodating chamber and has a buffer surface 41, and at least part of the buffer surface 41 is arranged opposite to the liquid outlet hole 21. In this way, when the staff operates the liquid inlet device 20 to transport liquid into the accommodating cavity to clean the resin layer located in the accommodating cavity, since the buffer surface 41 of the buffer structure 40 is arranged relative to the liquid outlet hole 21 of the liquid inlet device 20, the buffer structure 40 can block and buffer the liquid flowing to the discharge device 30, and reduce the flow rate of the liquid to reduce the impact load between the liquid and the discharge device 30, thereby avoiding excessive impact force between the liquid and the discharge device 30 causing deformation or even damage of the discharge device 30, thereby solving the problem of easy damage of the discharge device in the prior art of the ion exchanger, extending the service life of the discharge device 30, and reducing the maintenance frequency of the staff.

[0029] In this embodiment, the liquid inlet device 20 is a water distribution pipe disposed in the accommodating cavity, and a plurality of liquid outlet holes 21 are disposed on the water distribution pipe to uniformly transport the liquid into the accommodating cavity.

[0030] like Figure 2 As shown, the buffer surface 41 and the liquid outlet direction of the liquid inlet device 20 are arranged at a first angle A1, and the first angle A1 satisfies: 45°≤A1≤70°. In this way, the above arrangement, on the one hand, makes the angle between the buffer surface 41 and the liquid flow direction more appropriate, so as to avoid the damage of the buffer structure 40 caused by excessive impact force between the liquid and the buffer structure 40 while ensuring that the buffer structure 40 has a good buffering effect, which not only improves the buffering reliability of the buffer structure 40, but also prolongs the service life of the buffer structure 40; on the other hand, it makes the value of the first angle A1 more flexible and diverse, so as to adapt to different working conditions and usage requirements, and also improves the processing flexibility of the staff.

[0031] In this embodiment, the first angle A1 between the buffer surface 41 and the liquid outlet direction is 30°.

[0032] It should be noted that the value of the first angle A1 between the buffer surface 41 and the liquid outlet direction is not limited thereto, and can be adjusted according to working conditions and usage requirements. Optionally, the value of the first angle A1 is 20°, 25°, 35°, 40°, or 45°.

[0033] In this embodiment, the buffer structure 40 is plate-shaped and is arranged on the liquid inlet device 20, and the plate surface of the buffer structure 40 facing the liquid inlet device 20 is the buffer surface 41. In this way, the above arrangement makes the structure of the buffer structure 40 simpler, easier to process and realize, which not only reduces the processing cost of the buffer structure 40, but also reduces the processing difficulty of the staff; on the other hand, it makes the formation of the buffer surface 41 easier to process and realize.

[0034] Specifically, the buffer structure 40 is fastened to the end fixing piece of the water supply pipe by a special fastener to achieve the installation of the buffer structure 40 .

[0035] In this embodiment, at least part of the buffer structure 40 is made of stainless steel. Thus, the above configuration enables the buffer structure 40 to have good rust and corrosion resistance, thereby extending the service life of the buffer structure 40.

[0036] Specifically, the buffer structure 40 is made of 316L stainless steel.

In this way, by supporting the drain device 30 through the first supporting structure 50, on the one hand, the installation stability of the drain device 30 can be improved to prevent the drain device 30 from loosening or even falling off under the impact of the liquid; on the other hand, the first supporting structure 50 can also assist the drain device 30 in resisting the impact force of the liquid to prevent the drain device 30 from being deformed or even damaged, thereby extending the service life of the drain device 30.

[0038] Optionally, the housing 10 is cylindrical, the drainage device 30 includes a main pipeline 31 and a plurality of branch pipelines 32 connected to the main pipeline 31, the plurality of branch pipelines 32 are arranged at intervals along the extension direction of the main pipeline 31, and the first support structure 50 includes a rod-shaped support body 51 and a connector 52, the rod-shaped support body 51 is connected to the main pipeline 31 and / or the branch pipeline 32. The connector 52 is arranged on at least one end of the rod-shaped support body 51, and the rod-shaped support body 51 is connected to the inner wall of the housing 10 through the connector 52. There are multiple first support structures 50, and the multiple first support structures 50 are arranged at intervals along the radial direction of the housing 10. In this way, the above arrangement realizes the installation and fixation of the rod-shaped support body 51 through the connector 52 on the one hand; on the other hand, the rod-shaped support body can increase the assembly area between the first support structure 50 and the drainage device 30, thereby improving the support stability of the first support structure 50 on the drainage device 30. At the same time, the above arrangement makes the number and arrangement of the first support structures 50 more flexible and diverse to adapt to different working conditions and usage requirements, and also improves the processing flexibility of the staff.

[0039] In this embodiment, connecting members 52 are provided at both ends of the rod-shaped supporting body 51 to increase the connection area between the rod-shaped supporting body 51 and the housing 10 , thereby improving the installation stability of the first supporting structure 50 .

In this way, the first support structure 50 is supported by the second support structure 60, and then the drainage device 30 is supported, which further improves the installation stability of the drainage device 30 on the one hand; on the other hand, the liquid impact load resistance strength of the drainage device 30 can be further improved, so as to further extend the service life of the drainage device 30.

Among them, the columnar support body 61 and the rod-shaped connecting member 62 are arranged at a second angle, and there are multiple second support structures 60, and the multiple second support structures 60 are arranged at intervals along the radial direction of the housing 10. In this way, there is a larger contact area between the connecting member arranged in a rod shape and the first support structure 50, so as to improve the support stability of the second support structure 60 to the first support structure 50. At the same time, the above-mentioned setting makes the structure of the second support structure 60 simpler, easier to process and realize, thereby reducing the processing cost of the second support structure 60 and the processing difficulty of the staff; on the other hand, it makes the angle between the columnar support body 61 and the rod-shaped connecting member 62 more flexible and diverse, so as to adapt to different working conditions and use requirements, thereby improving the processing flexibility of the staff.

[0044] In this embodiment, the second angle between the columnar supporting body 61 and the rod-shaped connecting member 62 is set to 90°, so that the extending direction of the rod-shaped connecting member 62 can match the shape of the first supporting structure 50 .

[0045] like Figure 1 As shown, the second support structure 60 further includes an annular connector 63, which is sleeved on the columnar support body 61 and is used to connect to the bottom wall of the housing 10. In this way, by providing the annular connector 63, the connection area between the columnar support body 61 and the inner wall of the housing 10 can be increased to improve the connection stability between the columnar support body 61 and the inner wall of the housing 10.

[0046] In this embodiment, the columnar supporting body 61 and the annular connecting member 63 are connected to the inner wall of the housing 10 by welding.

[0047] Optionally, the first support structure 50 and the second support structure 60 are both made of 316L stainless steel material to extend the service life of the first support structure 50 and the second support structure 60 .

In this way, the above arrangement, on the one hand, filters the impurities in the liquid flowing to the liquid passage hole 13 through the filter plate 70 to prevent the impurities from clogging the liquid passage hole 13, thereby improving the operating stability of the ion exchanger; on the other hand, the filter plate 70 can avoid the columnar support body 61 to achieve the installation of the second support structure 60.

[0049] Specifically, the filter plate 70 is a filter cap porous plate.
