[0023] The sedimentation section 1, the fluidization section 4 and the water and drug inlet section 5 are arranged in sequence from top to bottom. The upper end of the sedimentation section 1 is provided with a crystal inducing carrier addition port for adding the crystal inducing carrier into the fluidized bed so that the elements to be recovered adhere to the surface of the crystal inducing carrier, and the crystal inducing carrier is quartz sand; the side wall of the sedimentation section 1 is provided with a water production port 12 and a circulating water outlet 11, the water and drug inlet section 5 is provided with a water inlet 6, a drug inlet 9 and a circulating water inlet 7, the circulating water outlet 11 is connected to the circulating water inlet 7 through a circulating pipeline, and a circulating pump 15 is provided on the circulating pipeline; the drug inlet 9 is used to add drugs to the fluidized bed to adjust the hardness of the water to be treated.

[0024] Specifically, in order to solve the problem that the suspension formed by clarifying the elements to be recovered when treating industrial water by chemical methods in the prior art is not only low in treatment efficiency but also has a high water content in the suspension, the fluidized bed provided by the utility model can input the water to be treated through the water inlet 6 on the water inlet and drug inlet section 5, and input the agent through the drug inlet 9. After the treatment water is added with the agent, it moves from bottom to top in the fluidized bed until it enters the sedimentation section 1 and is output through the water production port 12 on the sedimentation section 1. The crystal-inducing carrier can be added to the fluidized bed through the crystal-inducing carrier addition port on the sedimentation section 1. During the movement of the water to be treated, the elements to be recovered in the water to be treated are attached to the surface of the crystal-inducing carrier, so that the elements to be recovered are recovered. The fluidized bed has a simple structure, no internal components, and low cost. At the same time, the fluidized bed can increase the clarification speed of the water to be treated in the next process and reduce the water content of the recovered elements to be recovered by adding the crystal-inducing carrier inside and using the crystal-inducing carrier to recover the elements to be recovered, so as to facilitate further treatment of the elements to be recovered.

[0025] Furthermore, the sedimentation section 1, the fluidization section 4 and the water and drug inlet section 5 are all vertical cylindrical structures.

[0026] Optionally, the lower end of the sedimentation section 1 is connected to the fluidization section 4 through a first tapered portion, and the upper end of the water and drug inlet section 5 is connected to the fluidization section through a second tapered portion.

[0027] Specifically, the diameters of the sedimentation section 1, the fluidization section 4 and the water and drug inlet section 5 decrease in sequence.

[0028] Optionally, the fluidizing section 4 is provided with at least one sight glass 2 and at least one support seat 10 .

[0029] Specifically, the sight glass 2 can conveniently observe the flow conditions in the fluidizing section 4, and the support seat 10 is connected to the outside of the fluidizing section 4 to support and fix the fluidized bed.

[0030] In this embodiment, the sight glass 2 is connected to the fluidizing section 4 via the connecting flanges 3 at the upper and lower ends thereof.

[0031] Optionally, 1-5 sight glasses 2 are vertically arranged at intervals on the fluidizing section 4 .

[0032] In this embodiment, three viewing mirrors 2 are provided, which are respectively distributed at the upper end, the lower end and the middle of the fluidizing section 4 .

[0033] Optionally, an overflow port 13 is provided on the side wall of the sedimentation section 1 above the water production port 12, and the overflow port 13 is used to connect an overflow pipeline, and the overflow pipeline is connected to a raw water storage device.

[0034] Specifically, the overflow port 13 is used for the overflow of water in the sedimentation area. When problems occur in the water production port 12 and the downstream components of the water production port 12 and water cannot be produced normally, the overflow port 13 and the overflow pipeline can return the overflow water into the raw water storage equipment, avoiding the difficulty in controlling and collecting the overflow water.

[0035] Furthermore, the overflow port 13 is arranged 1-10 cm below the upper edge of the sedimentation zone, preferably 5 cm; the overflow port 13 is 1-10 cm higher than the water outlet 12, preferably 5 cm; the water outlet 12 is 30-100 cm higher than the circulating water outlet 11, preferably 50 cm.

[0036] Optionally, the water inlet 6 is connected to a water inlet pipeline, a water inlet pump 17 is provided on the water inlet pipeline, and the water inlet pipeline is connected to a raw water storage device.

[0037] Specifically, the water inlet pipeline inputs the water to be treated in the raw water storage device into the fluidized bed through the water inlet pump 17 thereon.

[0038] In this embodiment, the raw water storage device is a raw water storage tank 16, which is used to store water to be treated.

[0039] Optionally, the drug inlet 9 is connected to a drug inlet pipeline, a drug inlet pump 18 is provided on the drug inlet pipeline, and the drug inlet pipeline is connected to a drug storage container.

[0040] Specifically, the drug feeding pipeline inputs the drug in the drug storage container into the fluidized bed through the drug feeding pump 18 thereon.

[0041] In this embodiment, the medicine storage container is a medicine storage tank 19 .

[0042] In this embodiment, the crystal-inducing carrier is quartz sand, which is fluidized in the fluidizing section 4, and the reagent is a sodium carbonate solution, which is mixed with the water to be treated to adjust its hardness, that is, pH value.

[0043] Optionally, the water production port 12 is connected to a water production pipeline, and the water production pipeline is connected to a water production storage device.

[0044] In this embodiment, the produced water storage device is a produced water storage tank 20 .

[0045] Optionally, a conduit 14 is further included, which is connected to the water inlet and medicine inlet section 5 along the tangent direction of the water inlet and medicine inlet section 5 , and the water inlet 6 and the circulating water inlet 7 are both arranged on the conduit 14 .

[0046] Specifically, the water inlet 6 and the circulating water inlet 7 are both arranged on the same confluence pipe 14. After confluence through the confluence pipe 14, the water to be treated flows into the fluidized bed. Under the action of the circulating pump 15 on the circulating pipeline, the water to be treated can circulate into the fluidized bed, which can not only improve the treatment effect, but also ensure a higher flow rate of the water to be treated in the fluidized bed; the confluence pipe 14 is arranged along the tangential direction of the water inlet and drug inlet section 5, so that the water to be treated entering the fluidized bed can form a vortex when entering, thereby improving the treatment effect.

[0047] In this embodiment, a solid-liquid separator is also included. The solid-liquid separator is arranged on the circulation pipeline. After the water flowing out of the circulating water outlet 11 enters the solid-liquid separator to separate the suspended matter, the supernatant is pumped into the circulating water inlet 7 by the circulating pump 15.

[0048] Optionally, the drug inlet 9 is arranged above the water inlet 6 and the circulating water inlet 7 , and a drain valve 8 is arranged at the lower end of the water and drug inlet section 5 .

[0049] Specifically, among the water inlet 6, circulating water inlet 7, drug inlet 9 and drain valve 8 on the water and drug inlet section 5, the drug inlet 9 is located at the highest position and the drain valve 8 is located at the lowest position.

[0050] When the fluidized bed provided by the utility model is used:

[0051] The water to be treated is fed into the fluidized bed through the water inlet 6;

[0052] Add medicine into the fluidized bed through the medicine inlet 9;

[0053] Adding a crystal-inducing carrier into the fluidized bed through a crystal-inducing carrier adding port;

[0054] The produced water is output through the water outlet 12 .

[0055] Specifically, the fluidized bed inputs the water to be treated through the water inlet 6 on the water inlet and drug inlet section 5, inputs the drug through the drug inlet 9, and adds the crystal-inducing carrier into the fluidized bed through the crystal-inducing carrier addition port on the sedimentation section 1. After the treatment water is added with the drug, it moves from bottom to top in the fluidized bed until it enters the sedimentation section 1 and is output through the water production port 12 on the sedimentation section 1. The crystal-inducing carrier is fluidized in the fluidizing section 4. During the movement of the water to be treated, the elements to be recovered in the water to be treated are attached to the surface of the crystal-inducing carrier, so that the elements to be recovered are recovered, and at the same time, the drug adjusts the hardness of the water to be treated. The fluidized bed can increase the clarification speed of the water to be treated in the next process and reduce the water content of the recovered elements to be recovered by adding the crystal-inducing carrier inside and using the crystal-inducing carrier to recover the elements to be recovered, so as to facilitate the further treatment of the elements to be recovered.

[0056] The fluidized bed provided by the utility model can be applied in industrial water treatment to adjust the hardness of industrial water and to recover the elements to be recovered in industry.

[0057] Specifically, the above-mentioned fluidized bed is used in industrial water treatment. Industrial water enters the fluidized bed from the water inlet 6, flows upward along the fluidized bed, and produces water from the water outlet 12. In this process, the crystal-inducing carrier is added into the fluidized bed through the crystal-inducing carrier addition port to realize the attachment and recovery of the elements to be recovered, and the addition of drugs into the fluidized bed through the drug inlet 9 realizes the softening of the industrial water, reduces the pH value of the industrial water, and realizes the treatment of the industrial water. Compared with the prior art that uses chemical methods to treat industrial water, the elements to be recovered form a suspension, and the recovery of the elements to be treated is realized by clarifying the suspension formed by the elements to be recovered. The use of the above-mentioned fluidized bed device for industrial water treatment can not only improve the treatment efficiency, but also the water content of the recovered elements to be recovered is low, which is easy to further process the elements to be recovered.

[0058] The various embodiments of the utility model have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
