TECHNICAL FIELD
[0001] The utility model relates to water treatment technical field, concretely is a kind of defluorination resin regeneration waste liquid recycling treatment device. BACKGROUND
[0002] In recent years, with the acceleration of industrialization and urbanization, fluoride pollution caused by wastewater discharge is becoming increasingly serious, which has become an important factor affecting the ecological environment, and the discharge and treatment of fluorides have been increasingly valued.
[0003] Currently, the main treatment processes for industrial fluorine-containing wastewater are calcium salt precipitation method, coagulation sedimentation method and adsorption method, etc. Among them, the calcium salt precipitation method mainly forms calcium fluoride by adding lime or calcium chloride and fluoride ions to achieve the purpose of removing fluorides, but it has problems such as low removal efficiency and the fluorides in effluent cannot meet the demand for deep defluorination.
[0004] When treating the regeneration waste liquid, a large amount of reagents and regeneration waste liquid reactions are required, but the amount of mud in the waste liquid is large, which reduces the rate of treating the regeneration waste liquid.
[0005] Therefore, a defluorination resin regeneration waste liquid recycling treatment device is proposed to solve the above problems. SUMMARY

The base has a slag discharge port and a second water inlet at its bottom. By first using a waste liquid conditioning tank to even out the water quality and quantity of the resin regeneration waste liquid, the required dosage of the reagent can be determined based on the water volume, thus enabling precise control of the reagent. Then, the waste liquid is quickly pumped into the pipeline mixer by a waste liquid booster pump to accelerate the mixing of the waste liquid and the reagent. Because the pipeline mixer has a spiral structure, the waste liquid and the reagent are continuously cut and recombine as they flow through the spiral channel, thereby accelerating the mixing time and increasing the mixing effect. Finally, the mixture enters the integrated reaction device for sedimentation to remove the sludge. At the same time, the holes on the surface of the baffle reduce the impact of the water flow on the baffle.

Then, the regenerated liquid is drawn and mixed by the regenerated liquid booster pump, and finally enters the regenerated liquid purification tank for reaction, which can purify the resin regeneration waste liquid and turn it into regenerated liquid.
[0009] Preferably, the base has a precision filter at the top; the precision filter has a fourth water inlet at the top; and the base has a third water outlet at the bottom. By adding a precision filter, the suspended particles inside the regenerated liquid can be reduced, thereby increasing the purity of the regenerated liquid and reducing impurities inside the regenerated liquid.
[0010] Preferably, a filter plate is fixedly attached to the surface of the integrated reaction device; the filter plate is located at the top of the integrated reaction device; by adding the filter plate, the regenerated liquid can be initially filtered, thereby reducing larger particulate impurities.
[0011] Preferably, the surface of the filter plate is connected to a solid-liquid separator; the solid-liquid separator and the filter plate are arranged correspondingly; by adding a solid-liquid separator, the sludge inside the regenerated liquid can be blocked and filtered.

[0013] Preferably, the connection between the baffle and the integrated reaction device is arc-shaped; by setting the connection arc-shaped, the accumulation of crystallized sludge in the dead zone of the baffle and the hydraulic impact can be reduced.
[0014] The advantages of this utility model are:
[0015] 1. The fluoride-removing resin regeneration waste liquid recycling and treatment device of this utility model first uses a regeneration waste liquid conditioning tank to uniformly measure the water quality and quantity of the resin regeneration waste liquid, which can accelerate the determination of the required dosage of the agent based on the water volume, thereby achieving precise control of the agent. Then, the regeneration waste liquid is quickly pumped into the pipeline mixer by a regeneration waste liquid lift pump to accelerate the mixing of the resin regeneration waste liquid and the agent. Because the pipeline mixer has a spiral structure, the resin regeneration waste liquid and the agent are continuously cut and recombine as they flow through the spiral channel, thereby accelerating the mixing time and increasing the mixing effect.

Then, the first water outlet 13 is connected to the regeneration waste liquid lifting pump 14, so that the resin regeneration waste liquid is passed through the regeneration waste liquid regulating tank 11 for uniform water quality and quantity. The waste liquid is pumped by pump 14 to the inside of the pipeline mixer 15 for mixing with the recovered reagent inside the pipeline mixer 15. After mixing, the waste liquid enters the bottom of the integrated reactor 16 through the second inlet 19, forming calcium fluoride crystal sludge at the bottom of the integrated reactor 16. This sludge then enters the collection system through the sludge discharge port 18, while the supernatant passes through the baffle 17 to the top of the integrated reactor 16, thus separating the liquid and sludge. By first using the regenerated waste liquid equalization tank 11 to uniformize the water quality and quantity of the resin regeneration waste liquid, the judgment based on the water volume can be accelerated. The required dosage of the reagent is precisely controlled. Then, the resin regeneration waste liquid is quickly pumped into the pipeline mixer 15 by the regeneration waste liquid lift pump 14 for mixing, which can accelerate the mixing of resin regeneration waste liquid and reagent. Because the pipeline mixer 15 has a spiral structure, the resin regeneration waste liquid and reagent are continuously cut and recombine as they flow through the spiral channel, thereby accelerating the mixing time and increasing the mixing effect. Finally, it enters the integrated reaction device 16 for sedimentation to remove sludge. At the same time, the holes on the surface of the baffle 17 reduce the impact of water flow on the baffle 17.

Then, the third inlet 21 is connected to the integrated reaction device 16, and the second outlet 22 is connected to the regenerated liquid... The connection of the booster pump 24 allows the regenerated liquid booster pump 24 to draw the supernatant into the regenerated liquid purification tank 2, where the reaction takes place. Finally, the regenerated resin liquid is drawn into the regenerated liquid storage tank by the regenerated liquid booster pump 24. The purification agent can be added into the integrated reaction device 16 through the dosing port 23 to initially mix with the supernatant. Then, the regenerated liquid is drawn and mixed by the regenerated liquid booster pump 24. Finally, it enters the regenerated liquid purification tank 2 for reaction, which can purify the resin regeneration waste liquid and turn it into regenerated liquid.
[0026] like Figs. 1-3 As shown, the base 1 has a precision filter 3 on top; the precision filter 3 has a fourth inlet 31 on top; and the base 1 has a third outlet 32 on the bottom. During operation, after the resin regeneration waste liquid is purified inside the regeneration liquid purification tank 2, the regeneration liquid lift pump 24 is connected to the fourth inlet 31, so that the regeneration liquid flows into the precision filter 3 through the regeneration liquid lift pump 24, thereby filtering the regeneration liquid. After the regeneration liquid passes through the precision filter 3, it enters the regeneration liquid storage tank through the third outlet 32. By adding the precision filter 3, the suspended particles inside the regeneration liquid can be reduced, thereby increasing the purity of the regeneration liquid and reducing the impurities inside the regeneration liquid.
[0027] like Fig. 2 As shown, a filter plate 4 is fixedly attached to the surface of the integrated reaction device 16; the filter plate 4 is located at the top of the integrated reaction device 16; during operation, when the regenerated liquid is pumped into the regenerated liquid purification tank 2, it will first come into contact with the filter plate 4, at which time the filter plate 4 will filter the regenerated liquid; by adding the filter plate 4, the regenerated liquid can be initially filtered, thereby reducing larger particulate impurities.
[0028] like Fig. 2 As shown in the figure, the surface of the filter plate 4 is connected to a solid-liquid separator 5; the solid-liquid separator 5 and the filter plate 4 are arranged correspondingly; during operation, when the regenerated liquid passes through the filter plate 4, it will enter the interior of the solid-liquid separator 5. At this time, the solid-liquid separator 5 will separate the sludge inside the regenerated liquid into layers, thereby reducing the amount of sludge entering the regenerated liquid purification tank 2; by adding the solid-liquid separator 5, the sludge inside the regenerated liquid can be blocked and filtered.
[0029] likeFig. 2 As shown, a turbidimeter 6 is fixedly attached to the outer wall of the integrated reaction device 16; the turbidimeter 6 is located below the baffle 17; a probe 61 is fixedly attached to the output end of the turbidimeter 6; the probe 61 is through-hole installed on the integrated reaction device 16; during operation, when the resin regeneration waste liquid crystallizes at the bottom of the integrated reaction device 16, the sludge concentration inside the resin regeneration waste liquid can be determined by the data transmitted to the turbidimeter 6 through the probe 61; by installing the turbidimeter 6, the degree of sludge inside the resin regeneration waste liquid can be quickly observed.
[0030] like Fig. 2 As shown, the connection between the baffle 17 and the integrated reaction device 16 is arc-shaped; by setting the connection in an arc shape, the accumulation of crystallized sludge in the dead zone of the baffle 17 and the hydraulic impact can be reduced.
[0031] Working principle: First, the first inlet 12 is connected to the waste liquid pipeline. Then, the resin regeneration waste liquid is transferred through the first inlet 12 to the regeneration waste liquid conditioning tank 11 for uniform water quality and quantity. Then, the first outlet 13 is connected to the regeneration waste liquid lift pump 14, so that the resin regeneration waste liquid is transferred through the regeneration waste liquid lift pump 14 to the pipeline mixer 15 for mixing and reaction with the recovery agent inside the pipeline mixer 15. After mixing, it enters the bottom of the integrated reaction device 16 through the second inlet 19, so that calcium fluoride crystal sludge is formed at the bottom of the integrated reaction device 16. Then, this sludge enters the collection system through the sludge discharge port 18, while the supernatant reaches the top of the integrated reaction device 16 through the baffle 17, thereby separating the liquid and sludge. After the sludge is removed, the purification agent is added into the integrated reaction device 16 through the dosing port 23 to mix with the supernatant. Then, the third inlet 21 is connected to the integrated reaction device 16, and the second outlet 22 is connected to the regeneration liquid lift pump 24, so that the regeneration liquid lift pump... 24. The supernatant is pumped into the regeneration solution purification tank 2, where the reaction takes place. Finally, the resin regeneration solution is pumped into the regeneration solution storage tank via the regeneration solution lift pump 24. After the resin regeneration waste liquid is purified in the regeneration solution purification tank 2, the regeneration solution lift pump 24 is connected to the fourth inlet 31, allowing the regeneration solution to flow into the precision filter 3 for filtration. After passing through the precision filter 3, the regeneration solution enters the regeneration solution storage tank through the third outlet 32. The regenerated liquid is stored in a raw liquid storage tank. When the regenerated liquid is pumped into the regenerated liquid purification tank 2, it will first come into contact with the filter plate 4, at which time the filter plate 4 will filter the regenerated liquid. After the regenerated liquid passes through the filter plate 4, it will enter the solid-liquid separator 5. At this time, the solid-liquid separator 5 will separate the sludge inside the regenerated liquid into layers, thereby reducing the sludge entering the regenerated liquid purification tank 2. When the resin regeneration waste liquid crystallizes at the bottom of the integrated reaction device 16, the sludge concentration inside the resin regeneration waste liquid can be judged by the data transmitted to the turbidity meter 6 through the probe 61.
