Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment devices, in particular to a high-salinity wastewater crystallization and desalination device. Background Art

[0002] High-salt wastewater refers to wastewater containing a relatively high concentration of inorganic salts. This type of wastewater mainly comes from industrial production processes, such as chemical, pharmaceutical, food processing, petroleum refining, textile printing and dyeing industries, as well as seawater desalination, oil field reinjection water and other fields. At present, fluidized bed reactors are usually used to treat this type of wastewater. When using a fluidized bed reactor to treat this type of wastewater, it is necessary to add wastewater from bottom to top, and at the same time add drugs to the wastewater to make the salt substances in the wastewater crystallize and form a precipitate in the reactor. Then the precipitate is released from the sewage outlet at the bottom of the reactor to realize the recovery and utilization of the salt substances in the wastewater. At the same time, the treated clean water overflows from the upper side of the reactor to achieve the purification of the wastewater.

[0003] Although the current fluidized bed reactor can treat high-salt wastewater, because wastewater needs to be added to the reactor from bottom to top, the flowing wastewater will provide an upward force on the crystals during the process of adding wastewater, causing some small particles but crystals with a density greater than water to be suspended in the water and unable to settle to the bottom of the reactor normally. As a result, the suspended crystals cannot be discharged normally during the process of releasing the sediment in the reactor through the sewage outlet, causing these crystals to remain in the fluidized bed for a long time, thereby reducing the mass transfer efficiency. At the same time, these crystals will also hinder the sufficient mixing of the newly added wastewater and the medicine, thereby affecting the treatment efficiency of the newly added wastewater.

DETAILED DESCRIPTION

[0045] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0046] like Figure 1-Figure 8 As shown, the present invention proposes a high-salt wastewater crystallization and desalination device, which performs crystallization treatment on wastewater containing salt substances, including: a storage tank 1, a drainer is arranged on the upper side of the storage tank 1, and the storage tank 1 is provided with a sewage pipe and a feeding pipe, the sewage pipe is located on the lower side of the storage tank 1, and the feeding pipe is located on one side of the storage tank 1; an inner cylinder 3, which is fixed to the interior of the storage tank 1 through a connecting piece; a guide shell 4, which is fixed to the interior of the storage tank 1, and the guide shell 4 divides the interior of the storage tank 1 into two parts, and the guide shell 4 is used to guide the falling crystals; a feeder 6, which is arranged between the storage tank 1 and the guide shell 4, and the feeder 6 includes a plurality of water adding shells 14, and the water adding shells 14 are rotatably connected to the shielding ring 17, the water adding shell 14 and the shielding ring 17 are both provided with water adding holes uniformly distributed in the circumferential direction, the water adding holes on the water adding shell 14 are connected with the adjacent water adding holes on the adjacent shielding ring 17, the water adding shell 14 and the circumferentially uniformly distributed water adding holes on the adjacent shielding ring 17 are blocked and matched, the shielding ring 17 is fixedly connected with the second conical shell 16, the second conical shell 16 is rotatably connected with the first conical shell 15, the second conical shell 16 and the first conical shell 15 are both provided with two symmetrically distributed feed ports, the two feed ports on the second conical shell 16 are respectively connected and matched with the adjacent feed ports on the adjacent first conical shell 15, and the second conical shell 16 is blocked and matched with the two feed ports on the adjacent first conical shell 15.

[0047] In the above scheme, it is intended to solve the problem that in the process of discharging solid impurities in the existing fluidized bed reactor, the impurities suspended in the middle are easily affected by the water flow and cannot be discharged. An electric valve is installed on the sewage pipe of the storage tank 1. The inner cylinder 3 is located inside the storage tank 1, and the storage tank 1 is divided into two parts, the inner and outer parts. When the wastewater is transported into the storage tank 1, the wastewater mainly flows in the inner cylinder 3. A gap is provided between the inner cylinder 3 and the storage tank 1, so that the small-particle crystals can move downward between the inner cylinder 3 and the storage tank 1, thereby causing the small-particle crystals to reflux. During the use of this device, the wastewater is in the upper part of the guide shell 4. The two feed ports on the first conical shell 15 are the first feed ports, and the two feed ports on the second conical shell 16 are the second feed ports. By changing the positions of all the second conical shells 16, the relative positions of all the first feed ports and the adjacent second feed ports are changed, thereby changing the flow areas of the first feed ports and the adjacent second feed ports. At the same time, the connectivity between the circumferentially evenly distributed water addition holes on the water addition shell 14 and the adjacent water addition holes on the adjacent baffle ring 17 is changed to change the coverage of the wastewater flowing out of the water addition shell 14.

[0048] Furthermore, the guide shell 4 is composed of a circular ring and a conical shell, wherein the upper side of the circular ring of the guide shell 4 is provided with an inclined surface having the same inclination angle as that of the conical shell, for guiding the crystal.

[0049] Furthermore, the highest point of the first conical shell 15 is located at the lower part of the inclined surface of the circular ring of the guide shell 4 , so as to guide the crystal to the upper side of the conical shell 15 .

[0050] Furthermore, the feeder 6 also includes: a plurality of drug feed pipes 11, all of which are arranged inside the storage tank 1, and all of the drug feed pipes 11 are commonly connected to a total drug adding pipe; a plurality of water inlet pipes 12, all of which are arranged inside the storage tank 1, and all of the water inlet pipes 12 are commonly connected to a total water adding pipe, and a solenoid valve is arranged between the total water adding pipe and each water inlet pipe 12; drug adding shells 13, the number of which is consistent with the number of water adding shells 14, all of which penetrate the guide shell 4 and are fixedly connected thereto, and all of the drug adding shells 13 are equally divided into groups with the same number as the drug feed pipes 11, and each group of drug adding shells 13 is respectively fixedly connected and communicated with adjacent drug feed pipes 11, and the water adding shells 14 are penetrated and fixedly connected to adjacent drug adding shells 13, and all of the water adding shells 14 are equally divided into groups with the same number as the water inlet pipes 12, and each group of water adding shells 14 is respectively fixedly connected and communicated with adjacent water inlet pipes 12.

[0051] In the above scheme, the specific number of drug inlet pipes 11 and water inlet pipes 12 can be specifically selected by the staff in the actual use process. In the figure and the text, three are used as an example. The three drug inlet pipes 11 are in the same plane, and the three water inlet pipes 12 are also in the same plane. The diameters of the three drug inlet pipes 11 are different. The three drug inlet pipes 11 are mutually nested according to the size of the diameter. The diameters of the three water inlet pipes 12 are also different. At the same time, the three water inlet pipes 12 are also mutually nested according to the size of the diameter. The solenoid valve between the main water pipe and each water inlet pipe 12 is connected to the remote control terminal network. The specific number of drug adding shells 13 and water adding shells 14 can also be specifically selected by the staff in the actual use process. The figure and the text are shown as twelve examples, wherein each drug inlet pipe 11 has four drug adding shells 13 evenly distributed in the circumference, and each water inlet pipe 12 has four water adding shells 14 evenly distributed in the circumference. The water adding shells 14 are located inside the adjacent drug adding shells 13, and a gap is provided between the outer side of the water adding shell 14 and the inner side of the adjacent drug adding shell 13. The four drug adding shells 13 on the same drug inlet pipe 11 are set as a group, and the four water adding shells 14 on the same water inlet pipe 12 are set as a group, and the diameters of the circumscribed circles of the three groups of water adding shells 14 are all smaller than the inner diameter of the inner cylinder 3.

[0052] Furthermore, the projections of the feed ports on the first conical shell 15 and the second conical shell 16 on the horizontal plane are both fan-shaped, and the central angle of the fan-shaped is no more than 90°, so that the first conical shell 15 can completely block the symmetrically distributed feed ports on the adjacent second conical shell 16.

[0053] Furthermore, the height of the lower side surface of the first conical shell 15 is lower than the height of the upper side surface of the adjacent medicine adding shell 13, and the height of the upper side surface of the medicine adding shell 13 is lower than the height of the water adding hole on the adjacent water adding shell 14. The first conical shell 15 is used to intercept the medicine flowing out of the adjacent medicine adding shell 13 and the wastewater flowing out of the adjacent water adding shell 14, change the flow direction of the two liquids, and make the two liquids move along the lower side surface of the adjacent first conical shell 15 during the outflow process, so as to make the two liquids flow out in an umbrella shape to increase the coverage area of ​​the two liquids after flowing out.

[0054] Furthermore, the trigger assembly includes: a fixed plate 18, fixedly connected to the drain pipe on the lower side of the storage tank 1; a movable plate 19, slidably connected to the drain pipe on the lower side of the storage tank 1; a hydraulic push rod 20, fixedly connected to the storage tank 1 in a through-type manner, the telescopic end of the hydraulic push rod 20 is fixedly connected to the movable plate 19, and the fixed part of the hydraulic push rod 20 is externally connected to a hydraulic pump; drive rods 21, the number of which is consistent with the number of water adding shells 14, are all through-type rotatably connected to the fixed plate 18, each drive rod 21 is slidably connected to the adjacent water adding shell 14, the drive rod 21 is fixedly connected to the adjacent second conical shell 16, a guide groove is provided on the drive rod 21, and the movable plate 19 is inlaid with rolling balls in a number consistent with the number of the drive rods 21, and each rolling ball slides in the guide groove on the adjacent drive rod 21 respectively.

[0055] In the above scheme, the specific number of the driving rods 21 can also be specifically selected by the staff in the actual use process. The telescopic end of the hydraulic push rod 20 is in a retracted state at the beginning, and the rolling balls on the moving plate 19 are respectively located at the bottom of the guide grooves on the adjacent driving rods 21 at the beginning. The telescopic end of the hydraulic push rod 20 drives the moving plate 19 to move upward, and then the moving plate 19 squeezes the guide grooves on the driving rods 21 through the rolling balls thereon during the movement, so that all the driving rods 21 rotate synchronously under the squeezing force, so as to change the positions of all the second conical shells 16 at the same time.

[0056] Furthermore, the guide groove on the driving rod 21 is arc-shaped, and the angle of the guide groove on the driving rod 21 projected on the horizontal plane is not less than 90°.

[0057] In the above scheme, the rotation angle of the driving rod 21 is limited to ensure that after the driving rod 21 drives the adjacent second conical shell 16 to rotate to the extreme position, the two second feed ports on the second conical shell 16 can be fully connected with the adjacent first feed ports on the adjacent first conical shell 15, and at the same time ensure that after the shielding ring 17 is rotated, the circumferentially evenly distributed water addition holes on the shielding ring 17 can be completely misaligned with the adjacent water addition holes on the adjacent water addition shell 14.

[0058] When the device is used to treat the produced high-salt wastewater, the remote control terminal controls the water pump to transport the wastewater into the three water inlet pipes 12 through the main water pipe, and the wastewater flows into the three groups of water adding shells 14 respectively through the three water inlet pipes 12, and then the wastewater flows upward along the three groups of water adding shells 14 until the wastewater flows out along the circumferentially distributed water adding holes on the water adding shells 14 and the adjacent baffle rings 17. The wastewater is intercepted by the first conical shell 15 and diffuses circumferentially, increasing the area covered by the wastewater during the flow process, until the wastewater flows to the lowermost side of the first conical shell 15, and then the wastewater flows upward.

[0059] While the wastewater is transported into the three water inlet pipes 12, the remote control terminal controls the dosing pump to synchronously transport the medicine into the three medicine inlet pipes 11 through the main dosing pipe, so that the medicine flows into the three groups of dosing shells 13, and then the medicine moves upward between the dosing shells 13 and the adjacent water adding shells 14. The process of the medicine flowing to contact with the first conical shell 15 is the same as the flow process of the wastewater. At the same time, when the medicine flows out of the dosing shell 13, the medicine contacts the wastewater, even if the medicine and the wastewater impact each other, the mixing speed of the medicine and the wastewater is accelerated until the liquid level of the wastewater in the storage tank 1 is slightly higher than its upper side, and the wastewater in the storage tank 1 begins to overflow into the drainer. At this time, the remote control terminal needs to reduce the speed of transporting the medicine and wastewater into the storage tank 1, keep the wastewater in the storage tank 1 always in a state of overflowing into the drainer, and at the same time provide the wastewater in the storage tank 1 with sufficient reaction time, increase the contact probability of the wastewater in the storage tank 1 and the medicine, thereby enhancing the removal effect of the salt substances in the wastewater.

[0060] While the medicine and wastewater are being transported into the storage tank 1, the remote control terminal transports seed crystals into the storage tank 1 through the feeding pipe on the storage tank 1, so that the salt substances contained in the wastewater react with the medicine and then combine with the seed crystals to form crystals.

[0061] While the salt substances in the above-mentioned wastewater are generating crystals, the three groups of water-adding shells 14 continuously transport wastewater thereinto, so that the wastewater in the storage tank 1 always flows upward. At this time, crystal particles with large volume and density greater than that of water fall downward on the upper side of the guide shell 4, and are guided by the guide shell 4 to gather in the middle thereof, while crystal particles with small volume and density greater than that of water are suspended in the middle of the inner tube 3 (these crystal particles cannot fall on the guide shell 4 due to the influence of the water flow).

[0062] In the above process of conveying wastewater into the storage tank 1, since the maximum diameter of the circle where the three groups of water-adding shells 14 are located is smaller than the inner diameter of the inner cylinder 3, the coverage of the water flowing out of the three groups of water-adding shells 14 is located inside the inner cylinder 3, that is, the fluidity of the water inside the inner cylinder 3 is greater than the fluidity of the water between the inner cylinder 3 and the storage tank 1. Therefore, in the above process, when the wastewater flows to the top of the inner cylinder 3, the flow area of ​​the wastewater increases, so that the flowing wastewater diffuses from the middle to the surroundings, and then the crystals flowing with the wastewater are close to the inner wall of the storage tank 1, reducing the influence of the flow of the wastewater on the crystals. At the same time, when water flows through the gap between the lower side of the inner cylinder 3 and the guide shell 4, a pressure difference is generated at the gap between the lower side of the inner cylinder 3 and the guide shell 4, even if the waste water between the inner cylinder 3 and the guide shell 4 flows into the inner cylinder 3, and then the part of the crystals is affected by the flow of the waste water between the inner cylinder 3 and the guide shell 4, and moves downward along the gap between the inner cylinder 3 and the guide shell 4, so that the part of the crystals flows back to the inside of the inner cylinder 3, and then the part of the crystals is affected by the water flow and moves upward again, and the seeds in the part of the crystals continue to adsorb impurities in the waste water to increase the utilization rate of the seeds.

[0063] When the impurities accumulated on the guide shell 4 reach a certain volume, the remote control terminal starts the electric valve to connect the sewage pipe on the lower side of the storage tank 1, and discharges the impurities accumulated on the guide shell 4 and part of the wastewater to the outside. After the discharge is completed, the remote control terminal closes the electric valve, blocks the sewage pipe on the lower side of the storage tank 1, and then continues to treat the wastewater according to the above operation.

[0064] When the above-mentioned remote control terminal starts the electric valve, the remote control terminal starts the hydraulic pump, and the hydraulic pump delivers hydraulic oil to the fixed part of the hydraulic push rod 20, so that the telescopic end of the hydraulic push rod 20 drives the movable plate 19 to move upward synchronously, thereby driving all the driving rods 21 to rotate synchronously. At the same time, all the driving rods 21 respectively drive the adjacent second conical shells 16 and the adjacent shielding rings 17 to rotate synchronously. During the rotation of the second conical shells 16, each second conical shell 16 respectively drives the two second feed ports thereon to rotate synchronously, so that the second The two second feed ports on the conical shell 16 are respectively connected to the adjacent first feed ports on the adjacent first conical shell 15. At the same time, as the second conical shell 16 continues to rotate, the connection areas between the two second feed ports on the second conical shell 16 and the adjacent first feed ports on the adjacent first conical shell 15 continue to increase. During the rotation of the blocking ring 17, the blocking ring 17 continuously blocks the circumferentially uniformly distributed water adding holes on the adjacent water adding shell 14, thereby causing the circumferentially uniformly distributed water adding holes on the water adding shell 14 to continue to decrease during the rotation of the blocking ring 17.

[0065] Until the telescopic end of the hydraulic push rod 20 moves upward to the limit position, the movable plate 19 moves upward to the limit position synchronously. At this time, all the first feed ports are connected with the adjacent second feed ports, and the water adding holes uniformly distributed circumferentially on the shielding ring 17 are misaligned with the adjacent water adding holes on the adjacent water adding shell 14, so that the wastewater cannot flow into the storage tank 1 through the water adding holes on the shielding ring 17 and the water adding shell 14. That is, at this time, the wastewater can flow directly upward along the first feed port and the adjacent second feed port, thereby gathering the flowing wastewater and reducing the area covered by the wastewater during the flow process, that is, reducing the influence of the wastewater in the three groups of water adding shells 14 on the stability of the wastewater already in the storage tank 1 after flowing out, thereby increasing the sedimentation rate of the crystals suspended in the storage tank 1, and increasing the removal effect of the solid impurities in the storage tank 1.

[0066] After the impurities are discharged, the remote control terminal starts the hydraulic pump in reverse to extract the hydraulic oil in the fixed part of the hydraulic push rod 20, so that the telescopic end of the hydraulic push rod 20 is reset to the initial position and then drives all the second conical shells 16 to reset to the initial position synchronously, so as to continue to remove the salt substances contained in the wastewater. After the wastewater treatment is completed using this device, the staff shuts down the above device and discharges the residual wastewater in the storage tank 1. Then the staff inspects the storage tank 1 and other parts inside it for subsequent normal use.

[0067] Furthermore, if Figure 2 , Figure 3 , Fig. 9 and Fig.10 As shown, it also includes: a connecting frame 22, which is fixedly connected to the inside of the inner tube 3, and the connecting frame 22 is connected to the inner tube 3; there are multiple arc-shaped telescopic plates 23, all of which are fixedly connected to the connecting frame 22, and the telescopic parts of the arc-shaped telescopic plates 23 are slidably connected to the connecting frame 22, and the arc-shaped telescopic plates 23 are used to change the communication area between the connecting frame 22 and the inner tube 3; a liquid storage ring 25, which is fixedly connected to the inside of the inner tube 3, and the liquid storage ring 25 is connected to the hydraulic pump through a connecting pipe; a rotating ring 24, which is rotatably connected to the inside of the liquid storage ring 25, and the telescopic parts of all the arc-shaped telescopic plates 23 are fixedly connected to the rotating ring 24.

[0068] Furthermore, the diameter of the circumscribed circle of the innermost group of water-adding shells 14 is smaller than the inner diameter of the connecting frame 22 , and the center of the circumscribed circle is located on the central axis of the connecting frame 22 , so that the wastewater flowing out of the innermost group of water-adding shells 14 flows inside the connecting frame 22 .

[0069] In the above scheme, the connecting frame 22 is cut from a round tube. The specific number and structure of the arc-shaped telescopic plates 23 can be specifically selected by the staff during use. In the text and the figure, two symmetrically distributed plates are used as an example. The liquid storage ring 25 is filled with hydraulic oil. The rotating ring 24 synchronously pulls out the telescopic ends of the two arc-shaped telescopic plates 23 during the counterclockwise rotation to change the shielding area of ​​the two arc-shaped telescopic plates 23.

[0070] While the hydraulic pump delivers hydraulic oil to the fixed part of the hydraulic push rod 20, the hydraulic pump synchronously delivers hydraulic oil to the liquid storage ring 25, so that the rotating ring 24 is squeezed by the hydraulic oil and rotates, and then the rotating ring 24 drives the telescopic parts of the two arc-shaped telescopic plates 23 to move synchronously, that is, the telescopic parts of the two arc-shaped telescopic plates 23 are pulled out to reduce the connecting area between the connecting frame 22 and the inner tube 3, until the rotating ring 24 rotates to the limit position and the telescopic end of the hydraulic push rod 20 moves upward to the limit position, the remote control terminal shuts down the hydraulic pump, and at this time, the telescopic parts of the two arc-shaped telescopic plates 23 move synchronously to the limit position, that is, the two arc-shaped telescopic plates 23 cooperate with the connecting frame 22 to form a circular tube.

[0071] After the above-mentioned remote control terminal shuts down the hydraulic pump, the remote control terminal closes the solenoid valve between the main water pipe and the two outer water inlet pipes 12, so that the wastewater can only flow into the innermost water inlet pipe 12, and then can only flow out along the innermost group of water adding shells 14. At this time, the fluidity of the wastewater inside the connecting frame 22 is greater than the fluidity of the wastewater outside it, even if the stability of the wastewater outside the connecting frame 22 is increased, thereby increasing the sedimentation rate of the suspended crystals outside the connecting frame 22, so that the suspended crystals in the wastewater outside the connecting frame 22 can be discharged as much as possible, thereby avoiding the suspended crystals in the storage tank 1 affecting the normal reaction of the wastewater and the medicine, and reducing the removal effect of salt impurities in the wastewater.

[0072] After the solenoid valve between the above-mentioned main water pipe and the two outer water inlet pipes 12 is closed for a period of time, the remote control terminal opens the solenoid valve between the main water pipe and the two outer water inlet pipes 12, and simultaneously closes the solenoid valve between the main water pipe and the inner water inlet pipe 12, thereby causing the wastewater to move upward along the two groups of water adding shells 14 in the middle and outside. At this time, the fluidity of the wastewater outside the connecting frame 22 is greater than the fluidity of the wastewater inside it, increasing the sedimentation rate of the suspended crystals inside the connecting frame 22, thereby increasing the proportion of crystals discharged from the storage tank 1.

[0073] After all the crystalline impurities generated in the storage tank 1 are discharged according to the above operation, the remote control terminal closes the electric valve on the sewage pipe at the lower side of the storage tank 1, and adjusts the solenoid valves between the three water inlet pipes 12 and the main water supply pipe to a connected state to continue the crystallization desalination operation of the high-salt wastewater.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
