Description

Technical Field

[0001] The utility model relates to a strong magnetic anti-scaling crystallization granulation and hardness removal device, belonging to the technical field of water treatment devices. Background Art

[0002] The crystallization granulation fluidized bed utilizes the principle of heterogeneous crystallization, enabling the ions to rapidly nucleate and crystallize at the heterogeneous interface, achieving efficient removal of target ions. By adding appropriate seed particles, the crystallization granulation fluidized bed induces ions in the liquid phase to separate from the liquid phase and crystallize on the seed crystal surface.

[0003] The currently common crystallization circulation granulation fluidized bed device is mainly used for the removal of calcium hardness. It includes a cylinder, a water distribution area, a drug distribution area, a granulation area, a clear water area, a water and drug distribution head, etc., and the water and drug distribution devices are usually arranged on the same layer. In order to prevent the seed crystal particles from being diverted back into the water inlet cavity, the water outlet direction of the water distributor is usually set at an angle greater than 90° and less than 180° to the water flow direction in the fluidized zone. Therefore, if there is a drug distribution hole between the outer water distributor closest to the cylinder and the cylinder, the water flowing out of the water outlet in the direction of the cylinder may carry the drug toward the cylinder, and the drug and the hardness ions in the water will react on the cylinder to form scale. If there is no drug distribution hole between the outer water distributor closest to the cylinder and the cylinder, it is easy to cause uneven mixing of the water flow and the drug, resulting in high hardness of the outlet water and hydrolysis of the drug, and there is a problem of low utilization rate.

[0004] In order to solve this problem, in the prior art, there is an invention patent application with Chinese patent application publication number CN115304140A, which discloses an induced crystallization granulation fluidized bed softening water treatment device, which separates the water distribution area and the drug distribution area by setting a partition, and sets a mixed flow nozzle on the partition. The drug output by the drug distributor, the water in the water distribution area and the seeds added from the seed adding port will flow into the input port of the mixed flow nozzle and be sprayed out in a vertical upward direction from the output port, and then sink to the bottom along the inner wall of the tank, so that a circulating flow is formed in the tank body to increase the effect of crystallization granulation fluidization and water treatment, thereby improving the mixing uniformity of the drugs and improving the growth rate and efficiency of the crystal particles. However, the following problems still exist in actual use: in the case of high-speed water flow, due to the presence of particulate matter in the water, the particulate matter will collide with the internal components of the equipment during the water discharge process of the mixed flow nozzle, which may easily damage the equipment and make the equipment unusable. Moreover, since the mixed flow nozzle sprays upward, there will be a stagnant water area near the mixed flow nozzle, and the suspended matter will fall under the action of gravity, which may easily lead to the deposition of the suspended matter, which will cause scaling of the water distributor and the drug distributor, thereby affecting the uniformity of water and drug distribution, and further affecting the water quality and the utilization rate of the drug.

[0005] The utility model patent with the Chinese patent authorization announcement number CN221217394U discloses a chemical crystallization circulating granulation fluidized bed water treatment device. By providing a cover cap and other structures, when dispensing medicine, the medicine can enter the medicine dispensing tube through the medicine inlet at the lower end of the medicine passage, and then enter the diffusion chamber from the upper end of the medicine passage. After the medicine diffuses in the diffusion chamber, it flows out evenly from the medicine outlet on the brim of the cap and begins to mix with water, thereby achieving 360° medicine dispensing without dead angles, making the medicine and water mix more evenly and more fully, and improving the utilization rate of the medicine. However, in actual use, it was found that the residual medicine in the granulation area may react with hardness ions and precipitate, resulting in the phenomenon of scaling at the granulation area on the inner wall of the tank, which will affect the operation cycle of the device.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example: Please refer to Figures 1 to 4 The present embodiment provides a strong magnetic anti-scaling crystallization granulation and hardness removal device, including a cylinder 1, in which a water distribution area 2, a granulation area 3 and a clear water area 4 are arranged from the bottom to the top. A flower plate 5 is provided in the water distribution area 2 for separating the water distribution area 2 and the granulation area 3, and the granulation area 3 and the clear water area 4 are connected.

[0027] In order to avoid scaling and other phenomena in the granulation zone 3, a strong magnetic anti-scaling component 21 is provided on the cylinder 1. The strong magnetic anti-scaling component 21 is a device capable of generating a magnetic field in the prior art, and can be a permanent magnet or an electromagnetic device. The required magnetic field strength can be selected according to factors such as the material and thickness of the cylinder 1. The strong magnetic anti-scaling component 21 is provided on the outer wall of the cylinder 1 corresponding to the granulation zone 3. When the hardness removal device is in use, the strong magnetic anti-scaling component 21 can generate a magnetic field so that the residual reagents in the granulation zone 3 react quickly with the hardness ions near the cylinder 1 to form crystal nuclei, and inhibit the growth of the grains so that they can be carried away by the water flow instead of being deposited on the cylinder 1 to form scaling, thereby ensuring that scaling will not occur inside the cylinder 1 at the granulation zone 3, so as to extend the operating cycle of the hardness removal device.

[0028] In this embodiment, a plurality of water-medicine mixing components 6 are provided on the flower plate 5. The number and distribution of the water-medicine mixing components 6 on the flower plate 5 can be determined according to specific circumstances. The water-medicine mixing components 6 are used to mix the water and the medicine introduced.

[0029] In this embodiment, the water-drug mixing assembly 6 includes a water distribution pipe 7 that extends through the flower plate 5. This pipe connects the water distribution area 2 and the granulation area 3. A drug distribution pipe 8 is located within this pipe 7 and is coaxial with the pipe 7 to ensure uniform water distribution. The outer wall of the drug distribution pipe 8 is connected to the inner wall of the pipe 7 via a fixed connection block 13. A drug distribution cap 9 is located above the pipe 7. This cap is an arc-shaped, preferably hemispherical, structure. The inner arc portion of the medicine dispensing cover cap 9 is connected to the medicine dispensing pipe 8 by providing a connecting pipe 10 so that it can be fixed above the water dispensing pipe 7. The diameter of the medicine dispensing cover cap 9 is set to be larger than the diameter of the water dispensing pipe 7 to prevent the particles in the granulation area 3 from flowing back into the water dispensing pipe 7. A water outlet gap 12 is left between the brim of the medicine dispensing cover cap 9 and the top surface of the flower plate 5. The water outlet gap 12 is set to allow the water flowing in from the water dispensing pipe 7 to flow out from the water outlet gap 12 after being guided by the medicine dispensing cover cap 9. The medicine dispensing cover cap 9 and the connecting pipe 10 are both coaxially arranged with the medicine dispensing pipe 8 to ensure uniformity during subsequent medicine dispensing. A medicine outlet channel 11 is provided inside the medicine dispensing covering cap 9. One end of the medicine outlet channel 11 is connected to the end of the connecting tube 10 close to the medicine dispensing covering cap 9, and the other end passes through the brim of the medicine dispensing covering cap 9 to the outside. The passing ends of the medicine outlet channel 11 are evenly distributed along the brim of the medicine dispensing covering cap 9 to ensure uniformity during subsequent medicine dispensing.

[0030] To facilitate subsequent maintenance work, in this embodiment, the connecting tube 10 can be connected to the medicine dispensing tube 8 by a common detachable connection method, such as a threaded connection, so as to facilitate the subsequent replacement of the medicine dispensing shielding cap 9.

[0031] The cylinder 1 is also provided with a water inlet 14, a dosing pipe 15, a seed feeding port 17, a particle discharge port 18, a water outlet 19 and a manhole 20. The water inlet 14 is connected to the water distribution area 2. The water inlet 14 is used to introduce raw water from the outside into the hardness removal device. One end of the dosing pipe 15 is connected to the external dosing device, and the other end extends into the water distribution area 2 and is connected to the end of the dosing pipe 8 away from the connecting pipe 10 by providing a connecting hose 16. The external dosing device can feed the hardness removal device to the hardness removal device through the dosing pipe 15 and the connecting hose 16. The required reagents are added to the hardening device, the seed addition port 17 and the particle discharge port 18 are both connected to the granulation area 3, and the particle discharge port 18 is set close to the flower plate 5. The seed addition port 17 is used for the outside to add the required seeds into the hardening removal device, and the particle discharge port 18 is used to discharge the particles accumulated on the flower plate 5. The water outlet 19 and the manhole 20 are both connected to the clear water area 4. The water outlet 19 is used for the hardening removal device to discharge the produced water to the outside, and the manhole 20 is used for subsequent staff to enter the hardening removal device to perform the required maintenance work.

[0032] When this embodiment is working, by introducing raw water into the water inlet 14 and adding seeds to the seed addition port 17, the raw water can enter the water distribution area 2 from the water inlet 14, and then pass through the water distribution pipe 7 and, after being guided by the medicine distribution covering cap 9, enter the granulation area 3 evenly 360° without dead angles from the water outlet gap 12, so as to drive the seeds added in advance through the seed addition port 17 to make them fluidized. Then, by adding the corresponding agent into the dosing pipe 15, the agent finally enters the medicine outlet channel 11 through the connecting hose 16 and the medicine distribution pipe 8, and evenly enters the granulation area 3 along the medicine outlet channel 11 to carry out the corresponding reaction in the granulation area 3. Since the position where the medicine enters the granulation zone 3 is located outside the water flow entering the granulation zone 3, the water flow can carry the medicine outward without dead angles in 360 degrees and can continuously flush the brim of the medicine dispensing cover cap 9, thereby effectively avoiding the occurrence of scaling caused by the medicine flowing back into the water distribution pipe 7 and scaling at the medicine dispensing position of the medicine dispensing channel 11. After a period of fluidization in the granulation zone 3, due to the effect of hydraulic screening, the particle size of the seed particles in the granulation zone 3 presents a gradual distribution from large to small in the granulation zone 3. The large particles will accumulate on the flower plate 5, and the small particles will grow accordingly at the upper position of the granulation zone 3. After the particles accumulate to a certain extent on the flower plate 5, the particles can be discharged outward through the particle discharge port 18. The raw water passing through the water distribution area 2 and the granulation area 3 will finally enter the clean water area 4. The water entering the clean water area 4 is the produced water with calcium hardness removed, and the produced water can be discharged outward through the water outlet 19.

[0033] In order to further prevent the particles from flowing back into the water distribution pipe 7, in this embodiment, the end of the water distribution pipe 7 close to the connecting pipe 10 is set at a height higher than the flower plate 5 and not lower than the brim of the medicine distribution covering cap 9, so that the particles falling on the top surface of the flower plate 5 cannot flow back into the water distribution pipe 7 due to the height difference between the top of the water distribution pipe 7 and the top surface of the flower plate 5 and the brim of the medicine distribution covering cap 9, thereby ensuring the uniformity of the overall particle size distribution inside the hardness removal device to ensure the quality of subsequent products.

[0034] In order to further improve the mixing of medicine and water, in this embodiment, the brim of the medicine covering cap 9 is set in a tooth-shaped structure. The brim with the tooth-shaped structure can play the same role as the water outlet weir, and can ensure the uniformity of the water flow around it, and can increase the boundary of the medicine so that the medicine and water can be mixed more evenly. At the same time, after the water flows through the tooth-shaped structure, the tooth-shaped structure can play a role in disturbing the flow, thereby further enhancing the effect of mixing the medicine and water.

[0035] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
