Description

Technical Field

[0001] This utility model relates to the field of high-salt wastewater treatment technology, specifically to a novel integrated flocculation and sedimentation device. Background Technology

[0002] High-salinity wastewater treatment has always been a challenge in environmental protection. As environmental protection requirements become increasingly stringent, the requirements for the treatment of high-salinity wastewater are also becoming more stringent, especially the treatment of the mother liquor of high-salinity wastewater. Flocculation and sedimentation are usually used to remove suspended solids, colloids and some organic matter from the wastewater to assist in the subsequent desalination of the wastewater. Currently used high-salinity wastewater treatment equipment occupies a large area, and the mixing effect of mother liquor and reagents is poor. Uneven mixing of mother liquor and reagents can easily affect the subsequent treatment effect. At the same time, during the mixing and coagulation process, the "annular vortex" formed by the mixed liquor means that the water flow only rotates in the horizontal direction, resulting in little exchange between the upper and lower water layers. This can easily lead to "excessive reagent in the upper layer and insufficient reagent in the lower layer", which in turn can result in localized low reagent concentrations and insufficient floc formation.

[0003] In summary, there is a need for a device that can uniformly mix chemicals and thoroughly mix high-salt wastewater for flocculation and sedimentation. Utility Model Content

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] Example 1: To solve the technical problems in the background art, a novel integrated flocculation and sedimentation device is provided as follows: Combination Figures 1-4As shown, this utility model provides a novel integrated flocculation and sedimentation device, including a treatment box 1. The treatment box 1 is internally equipped with a first partition plate 11, a second partition plate 12, and a third partition plate 13, which divide the interior of the treatment box 1 into a mixing zone, a sedimentation zone, and a discharge zone. A mixing device 2 is provided in the mixing zone, with a mixing mechanism 3 in the middle. A dosing mechanism 4 for replenishing the chemical solution and mother liquor is provided at the end of the treatment box 1. A sedimentation mechanism 5 for separating flocs and a stirring mechanism 6 for assisting flocculation are provided in the middle of the sedimentation zone. The mixing device 2 includes a mixing cylinder 21, a dividing annular plate 22, and a mixing baffle 23. The mixing cylinder 21 is located inside the mixing zone. The inner side is provided with a dividing ring plate 22, which has a conical structure. Multiple dividing ring plates 22 are spaced apart, and multiple dividing ring plates 22 can form multiple mixing zones. The inner side of the mixing cylinder 21 is provided with mixing baffles 23, which are arranged in a ring and spaced apart. The mixing mechanism 3 includes a motor 31, a rotating rod 32, and mixing rods 33. The motor 31 is located at the top of the processing box 1. The output end of the motor 31 is provided with a rotating rod 32. Multiple sets of mixing rods 33 are provided on the outside of the rotating rod 32. The number of multiple sets of mixing rods 33 is different. In different mixing zones, the agent and the mother liquor can be mixed to different degrees multiple times, which is beneficial to improving the mixing effect of the agent and the mother liquor. As an improvement to the above scheme, the dosing mechanism 4 includes a mother liquor inlet pipe 41, a reagent inlet pipe 42, and a dosing pipe 43. The mother liquor inlet pipe 41 is located on the top side of the treatment tank 1, and the reagent inlet pipe 42 is located on the outside of the treatment tank 1. Multiple dosing pipes 43 are provided on the side of the reagent inlet pipe 42. The dosing pipes 43 penetrate into the inside of the mixing cylinder 21. A dosing valve 44 is provided in the middle of the dosing pipe 43. The dosing valve 44 can control the delivery of the reagent in the dosing pipe 43 into the mixing cylinder 21. Multiple dosing pipes 43 can deliver the reagent into the mixing cylinder 21 from multiple positions. In this way, the mixing of the reagent and the mother liquor is more uniform, which is conducive to improving the flocculation effect of the subsequent mother liquor.

[0016] The implementation principle of this embodiment is as follows: When treating high-salt wastewater mother liquor, the mother liquor is first fed into the mixing cylinder 21 of the mixing device 2 through the mother liquor feed pipe 41 of the dosing mechanism 4. At this time, the agent is fed into multiple positions in the mixing cylinder 21 through the agent feed pipe 42 and multiple dosing pipes 43. The mixing device 2 mixes the mother liquor and the agent in multiple areas and multiple times, so that the mixing of the mother liquor and the agent is more thorough and uniform, which is conducive to improving the flocculation and sedimentation effect of the mother liquor in the later stage.

[0017] Example 2: Figures 1-2 As shown, based on the above embodiments, this embodiment further provides the following: To ensure that the device can effectively flocculate high-salt wastewater, this embodiment provides the following design: The stirring mechanism 6 includes a second motor 61, a second rotating rod 62, a stirring impeller 63, and a guide plate 64. The second motor 61 is located at the top of the treatment tank 1. The output end of the second motor 61 is equipped with the second rotating rod 62. The bottom end of the second rotating rod 62 is equipped with the stirring impeller 63. The guide plate 64 is located on the side of the second partition plate 12, the side of the third partition plate 13, and the inside of the treatment tank 1. The guide plates 64 are arranged in a ring at intervals. Through the ring structure of the guide plates 64, the "rotating vortex" generated by the stirring impeller 63 can be broken during the process of stirring the mixture to assist flocculation, forcing the water flow to turn up and down, thereby making the mixing of the agent and the mother liquor more uniform and the floc formation more complete. In this embodiment, the settling mechanism 5 includes a baffle plate 51 and a settling plate 52. The baffle plate 51 is fixedly installed inside the treatment tank 1, and multiple sets of baffle plates 51 are distributed. The settling plate 52 is installed at the top of the settling zone, and multiple settling plates 52 are inclined. Multiple baffle plates 51 can increase the flow path of the mixed liquid, assist the flocs to settle and form supernatant. Multiple settling plates 52 with inclined distribution can further increase the flow path of the supernatant and improve the flocs falling and settling effect in the supernatant. In this embodiment, the discharge mechanism 7 includes a discharge pipe 1 71, a conical box 72, a discharge pipe 2 73, a discharge pipe 3 74, a discharge bottom pipe 75, and a discharge pump 76. The discharge pipe 1 71 is located at the bottom of the mixing zone, the conical box 72 is located at the bottom of the settling zone, the bottom of the conical box 72 is provided with the discharge pipe 2 73, the bottom of the discharge zone is provided with the discharge pipe 3 74, the discharge bottom pipe 75 is located below the processing tank 1, and the discharge bottom pipe 75 communicates with the discharge pipe 1 71, the discharge pipe 2 73, and the discharge pipe 3 74. The end of the discharge bottom pipe 75 is provided with the discharge pump 76, which can provide power for the discharge of the mixture that has settled to the bottom of the device. In this embodiment, an overflow plate 8 is provided at the top of the discharge area, and a discharge pipe 81 is provided at the end of the overflow plate 8. The edge of the overflow plate 8 is inclined, and the inclined top edge of the overflow plate 8 is lower than the top of the partition plate 13. The overflow plate 8 can assist the supernatant after sedimentation to be discharged from the device through the discharge pipe 81.

[0018] The implementation principle of this embodiment is as follows: When the mother liquor and the agent are mixed and enter the sedimentation zone, the motor 61 in the stirring mechanism 6 drives the rotating rod 62 to rotate, so that the stirring impeller 63 slowly stirs the mixture. During this process, the multiple sets of guide plates 64 arranged in a ring can break the "rotating vortex" generated by the impeller stirring, forcing the water flow to turn up and down, thereby making the mixing of the agent and the mother liquor more uniform and the floc formation more complete. Then, the mixture after floc formation will be sedimented to form supernatant and floc liquid. The supernatant will enter the discharge zone through the baffle 51 and sedimentation plate 52 of the sedimentation mechanism 5, and finally be discharged from the device by the overflow plate 8 and the discharge pipe 81.
