In the field of water treatment, whether it is wastewater treatment or water purification procedures, ion exchange resins can be used to remove ions in the water, so that the state of the treated water meets the requirements. Generally speaking, the ion exchange resin is placed in the tank, and the water to be treated is injected into the tank to make it contact with the ion exchange resin to remove the contained ions, and then drain the water for collection.

When the water after the action of the ion exchange resin is to be discharged to the outside of the tank, the ion exchange resin must be blocked from flowing out. For this reason, the current industry uses a water diffuser to smoothly discharge the treated water flow. A device that prevents the ion exchange resin from flowing out. The water diffuser is generally installed in the tank. After the untreated water is injected into the tank and contacts with the ion exchange resin to form the required water quality state, it can be discharged through the water diffuser.

In order to maintain the quality and effect of water treatment, the ion exchange resin should be replaced after a period of use, so that each batch of water has a stable and excellent treatment state. As mentioned above, affected by the structure of the water diffuser, when the ion exchange resin is discharged, the resin is very susceptible to being affected by the water diffuser, causing problems such as being stuck in the gap between the water diffuser and the bucket, resulting in a dead corner for removal. On the other hand, limited by the structure of the water diffuser, there will be more resin ineffective areas, that is, after the water to be treated is injected into the tank, it cannot contact the resin in some areas, resulting in a decrease in the utilization rate of the resin.

So how to reduce the aforementioned phenomenon The impact on water treatment is indeed a shortcoming that relevant manufacturers urgently need to overcome. In this regard, the creators have improved and designed, and then derived and conceived the technical features as described in this creation. Through the water dispersing device of this creative design, the ion exchange resin system can have a better utilization rate, and the efficiency of water treatment can be greatly improved. In the removal part, the ion exchange resin will not be stuck due to the structure of the water disperser. The situation cannot be eliminated. The following is a description of the technical content of the ion exchange resin tank and ion exchange resin tank water dispersing device proposed in this creation.

In order to enable those with ordinary knowledge in the field to clearly understand the content of this creation, the following text and diagrams are used for detailed descriptions. Please refer to Figures 1 to 5, which are part of the preferred embodiment of this creation.

The bottom side of the tank body 10 is provided with a resin discharge port 1021 to facilitate the removal of the ion exchange resin 2 and to adjust the discharge of the ion exchange tree 2 through various control methods. State, preferably, the resin discharge port 1021 is opened on the bottom surface 102, and the top side of the tank body 10 is provided with a water delivery port 103. Wherein, the bottom surface 102 may have a plurality of inclined surfaces or a concave arc as a whole to form a state of converging toward the center. This is beneficial to the discharge of the ion exchange resin 2. In this embodiment, the bottom surface 102 is Take a concave arc shape and form a state converging toward the center as an example. Furthermore, the structure design in which the bottom end of the barrel body 10 is condensed through the bottom surface 102, and the resin discharge port 1021 is located on the bottom surface 102 is more conducive to the discharge of the ion exchange resin 2, and the top side The water delivery port 103 is used as a structure for injecting the water to be treated into the tank body 10 or draining the backwashing water during backwashing.

Regarding the water dispersing device 11 of this creation, please refer to Figure 2. The water dispersing device 11 is arranged in the tank adjacent to the bottom side position. When used with the tank body 10 mentioned above, it is set in the The accommodating space 101 is adjacent to the bottom side of the barrel body 10. For the convenience of description, when the technical features of the water dispersing device 11 are explained later, the barrel body 10 will be used as a structure for matching applications. The above water dispersing device 11 can be applied to various ion exchange resin tanks. The water dispersing device 11 includes a main pipe 111, a plurality of first branch pipes 112, a plurality of second branch pipes 113 and a plurality of water dispersing heads 114. The main pipe 111 is the main pipe through which water flows out or flows in. In specific applications, one end of the main pipe 111 will protrude out of the tank body 10. The first branch pipes 112 are connected to the main pipe body 111, and respectively include a first The extension tube portion 1121 and at least one second extension tube portion 1122. Each of the first extension pipe portions 1121 is respectively extended from the main pipe body 111 to the right and/or left, and each of the second extension pipe portions 1122 is directed downward from the first extension pipe portion 1121, that is, toward the bottom surface 102 direction extension. Wherein, the aforementioned first extension pipe portions 1121 respectively extend from the main pipe body 111 to the right and/or left, which means that the first extension pipe portions 1121 extend from the main pipe body 111 to at least one side thereof, However, the right and/or left descriptions here do not limit the first extension tube portion 1121 to extend straight toward the main body 111. Depending on the application, the first extension tube portion 1121 is also It can form an inclined angle with the main pipe 111. The second branch pipes 113 and the main pipe 111 are connected to each other, and respectively extend downward from the main pipe 111, that is, toward the bottom surface 102. The water dispersing heads 114 are respectively arranged at one end of the second extension pipe portion 1122 and the second branch pipe 113, and have a plurality of micro holes 1141 for the water to flow in and out. Thereby, through the extension pipe portions 1122 and the second branch pipes 113 that extend downward, that is, toward the bottom surface 102, after the water dispersing device 11 is assembled to the tank body 10, the water dispersing heads 114 can be arranged adjacent to the bottom surface 10, so that after the water to be treated enters the tank body 10, it can contact almost all of the ion exchange resin 2 so as to increase the utilization rate of the resin. On the other hand, this structure can also allow the resin to be reasonably distributed in the barrel body 10, and will not be affected by the structure of the water dispersing device 11 when it is discharged outwards, and form a removal dead angle. Different from the previous installation of water diffusers, the water diffuser 11 of this creation is based on the previous installation concept that allows the inlet and outlet parts of the water flow to be arranged in a two-dimensional plane, instead of using downward extension pipelines to change The dispersing heads 114 that allow water to flow in and out are arranged so that the dispersing heads 114 are close to the bottom side of the tank body 10, so that the water to be treated can contact all the ion exchange resins as much as possible during application. Increasing the utilization rate of the ion exchange resin 2 can relatively have better processing efficiency. Moreover, the water dispersing device 11 can be designed according to the aforementioned structural concept, and its structure is further designed according to the matched barrel, so it also has the effect of preventing the resin from being stuck and difficult to remove. Wherein, when the water dispersing device 11 is correspondingly arranged on the bottom surface with a concave arc shape When inside the barrel body 10 of 102, the second branch pipes 113 and the second extension pipe portions 1122 are arranged in a long or short configuration according to the angle of the bottom surface 102 in response to the bundled bottom surface 102 , The closer the second branch pipe 113 and the second extension pipe portion 1122 appear to the center, the longer the length, and the closer the second extension pipe portion 1122 and the second branch pipe 113 to the peripheral edge, the shorter the length The state.

To reiterate here, through the water dispersing device 11, the effect of water and the ion exchange resin 2 can be effectively improved, so that the water can contact all the ion exchange resin 2 as much as possible, and then the dispersing head 114 The micropores 1141 are discharged outwards, and at the same time, the problem that the ion exchange resin 2 is stuck and cannot be removed and replaced can be eliminated. Furthermore, the ion exchange resin tank 1 of the present invention, when the ion exchange resin 2 is discharged, in addition to passing through the bottom surface 102 and the downward resin discharge port 1021, the ion exchange resin 2 can naturally follow the bottom surface 102. It is discharged outside to avoid the accumulation of dead spots. In conjunction with the water dispersing device 11, it is also possible to greatly reduce the situation that the ion exchange resin 2 is affected by the water dispersing heads 114 or pipelines and accumulates against the tank body 10. Especially for the processing system where the resin frequently enters and exits, it has excellent benefits. Therefore, this creation can indeed effectively improve the many deficiencies in the discharge of ion exchange resin 2 and water treatment in the existing barrels through the water dispersing device 11, so as to greatly reduce the ineffective use rate of resin, and the water dispersing device 11 can also avoid causing ions. The exchange resin 2 is stuck, and through the bucket shape of the water dispersing device 11, the resin removal efficiency can be enhanced.

Further, in order to have better installation convenience, the central axis of the first extension pipe portions 1121 of the water dispersing device 11 and the central axis of the second extension pipe portions 1122 can be arranged perpendicular to each other. And the central axis of the first extension tube portion 1121 can also be perpendicular to the central axis of the main tube body 111, so that the main tube body 111, the first extension tube portion 1121, and the second extension tube portion 1122 correspond to each other The X, Y, and Z axes are perpendicular to each other, so that in addition to facilitating assembly and manufacturing, it can also make the water flow path more uniform. In this configuration, the water dispersing device 11 covers the cross section of the tank body 10 , And with Have better application performance. In addition, based on the structural rigidity and stability of the water dispersing device 11, the first extension pipe portions 1121 can be arranged symmetrically, as shown in FIG. 3. That is, the first extension pipe portions 1121 of the first branch pipes 112 are respectively in a state of extending outward from both sides of the main pipe body 111 and arranged symmetrically to each other, which can make the overall structure more stable and the water flow The path can also be more symmetrical and spread everywhere.

Also based on the consideration of uniform arrangement, preferably, the main pipe body 111 coincides with the center line of the cross section of the barrel body 10, even if the main pipe body 111 is correspondingly located at the center of the barrel body 10, and the The extended pipe portions 1121 of the first branch pipe 112 can respectively extend toward the left and right sides of the main pipe body 111, so that the water dispersing device 11 collects the water treated by the ion exchange resin 2 or to the barrel When water is injected into the tank body 10 for backwashing operation, it can have a relatively uniform distribution state.

Further, the distance between any two adjacent water dispersing heads 114 is less than or equal to 15 cm, so as to prevent the distance between the water dispersing heads 114 from being too large to quickly discharge water. In specific implementation, the distance between the water dispersing heads 114 may be 15, 12, 8, or 5 cm, etc., and the shortest distance between the water dispersing heads 114 may be about 1, 2 cm. On the other hand, the distance between the water dispersing heads 114 and the bottom surface 102 can be less than or equal to 2 cm, so as to avoid being too far away from the bottom surface 102 and causing the water to be treated not to contact the ion exchange resin 2 close to the bottom surface 102. That is, it enters into the micropores 1141 of the water dispersing heads 114 and is discharged to the outside to improve the use efficiency of the ion exchange resin 2.

In this embodiment, the main pipe body 111 has a first section 1111 and a second section 1112, and the pipe diameter of the first section 1111 is larger than the second section 1112, and the first section 1111 is partly located outside the barrel body 10 and partly located inside the barrel body 10. In practical applications, the closer the main pipe 111 extends beyond the end of the barrel tank body 10, the larger the water volume due to the convergence effect. Therefore, the larger the pipe diameter of the first section 1111 is designed to be Let it go The water that the water head 114 enters the second branch pipes 113 and the second extension pipe portions 1122 can be smoothly discharged from the first section 1111 to the outside.

Regarding the dispersing heads 114, the specific structure can be one of a columnar body, an umbrella-shaped body, a frustum, or a combination thereof, and the micro-holes 1141 are in a state of being distributed throughout the dispersing heads 114 , The size of the micropores 1141 is smaller than that of the ion exchange resin 2, so as to prevent the ion exchange resin 2 from being carried out when the water flows in. The water dispersing heads 114 of the water dispersing device 11 can be of the same structure, or different structures can be used for matching applications. In this embodiment, the water dispersing heads 114 are frustums as an example, but they can also be Structures such as cylindrical, square pillar, umbrella or multi-stage umbrella.

For application, please refer to Figures 4 and 5. After placing the required ion exchange resin 2 in the tank body 10, the water to be treated can be injected from the water delivery port 103 on the top side of the tank body 10 Inside the barrel body 10. After the water contacts the ion exchange resin 2, the water quality can be adjusted. After the water flows downward through the ion exchange resin 2, it can enter the water dispersing heads 114 through the micropores 1141, and then follow the first The branch pipe 112 and the second branch pipes 113 converge to the main pipe body 111 and are discharged from the main pipe body 111 to the outside of the barrel body 10 to complete the water treatment operation. Wherein, the flow direction of the water can be controlled by pressure adjustment, so that the water treated by the ion exchange resin 2 in the tank body 10 can enter the dispersing heads 114 and flow out, and the distribution state of the ion exchange resin 2 in the figure is only It is a better indication. When the ion exchange resin 2 is to be discharged, as shown in FIG. 5, the resin discharge port 1021 of the bottom surface 102 is passed through, so that the ion exchange resin 2 in the accommodating space 101 is transferred outwards, and the water dispersing device With the structure of 11, the ion exchange resin 2 is not easy to stick to the water dispersing heads 114, and can smoothly flow to the resin discharge port 1021 along the converging bottom surface 102, eliminating dead corners for removal. Wherein, when the water dispersing device 11 is used in conjunction with other tanks, it is also the same as the aforementioned water-guided discharge process.

In summary, the ion exchange resin tank 1 and the water dispersing device 11 of the ion exchange resin tank in this creation use a special water dispersing pipe and a water dispersing head arrangement structure, so that the water dispersing device 11 can be covered on the resin tank section. At the same time, the dispersing head 114 is set close to the bottom surface of the tank, so that the resin can be located in the best planning space, and the water to be treated entering from the top of the tank can be in contact with all the resin as much as possible. Then it flows in from the micro-holes of the dispersing head and discharges from the end of the main pipe body outside the tank, which greatly reduces the ineffective use of the resin area, which relatively increases the use efficiency of the resin, and when matched with the condensed tank bottom surface , And enhance the resin discharge efficiency. Furthermore, the structure of the main pipe body, the first branch pipe, and the second branch pipe can be further restricted in structural changes, so as to improve the resin utilization rate and the reliability of removal.
