Description

Technical Field

[0001] This invention relates to the field of Microcystis aeruginosa removal devices, specifically to a Microcystis aeruginosa removal device based on carbon nanotube-quartz sand coupled adsorption. Background Technology

[0002] With the rapid development of nanotechnology, it has had a wide-ranging impact on the global socio-economic landscape. Currently, the industrialization of nanomaterials is booming both nationally and globally. Carbon nanotubes, as one-dimensional nanomaterials, are lightweight, have a perfectly connected hexagonal structure, and possess many exceptional mechanical, electrical, and chemical properties. In recent years, with the deepening research on carbon nanotubes and nanomaterials, their broad application prospects have been continuously revealed. Due to the very large aspect ratio and specific surface area of ​​carbon nanotubes, there is a strong attraction between them, coupled with van der Waals forces, making them prone to entanglement and aggregation. In aqueous solutions, they do not form a uniform and stable suspension. However, after ultrasonic treatment, a transient carbon nanotube suspension is formed. These suspended carbon nanotubes can effectively adsorb and flocculate algae in the water. Subsequently, the carbon nanotubes become unstable, and the algae adsorbed on them accelerate the sedimentation of the carbon nanotubes. Soon, the carbon nanotubes and algae settle together, thus achieving the purpose of algae removal. This characteristic makes carbon nanotubes a highly efficient algaecide.

[0003] One of the main hazards of cyanobacterial blooms is that some cyanobacteria can produce and release various types of algal toxins into the water. Processes such as raw water algae removal (physical, chemical, and biological methods), chemical coagulation, sedimentation, filtration, disinfection, activated carbon adsorption, and biodegradation have been successively applied to the control of microcystins (MCs) and have achieved significant results. However, due to technological limitations and insufficient understanding, the filtration devices using these processes are still unable to fundamentally remove Microcystis aeruginosa, and the filter media cannot be recycled and reused, which is detrimental to environmental protection and makes the cost of Microcystis aeruginosa removal devices too high. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a device for removing Microcystis aeruginosa based on carbon nanotube-quartz sand coupled adsorption.

[0005] The technical solution of the present invention is: a device for removing Microcystis aeruginosa based on carbon nanotube-quartz sand coupled adsorption, comprising a shell, and an adsorption unit and a flocculation unit disposed inside the shell;

[0006] The adsorption unit includes a cylindrical cavity that is laterally rotatable on the inner wall of the housing, a discharge switch on one side of the cylindrical cavity, an adsorption element on the other side of the cylindrical cavity, a toothed ring fixedly sleeved on the cylindrical cavity, a first motor mounted on a connecting rod on the inner wall of the housing via a connecting rod, and a gear fixedly connected at its center to the output end of the first motor; the gear meshes with the toothed ring; corresponding proximity sensors are provided directly above the discharge switch and the cylindrical cavity; a water inlet is provided at the right end of the cylindrical cavity, and a drain outlet is provided at the left end;

[0007] The adsorption element includes a first box body disposed on the side wall of the cylindrical cavity and communicating with the interior of the cylindrical cavity, and a second box body disposed outside the first box body and communicating with the first box body;

[0008] The first box is divided into several sub-cavities by multiple longitudinally arranged partitions; one side of the side wall of each sub-cavity is provided with an opening that communicates with the cylindrical cavity, and the opening is provided with a retractable door; the second box contains carbon nanotube-quartz sand and is provided with multiple feeding channels that correspond one-to-one with the other side of the side wall of each sub-cavity, and each feeding channel is provided with a control valve.

[0009] The bottom of the second box is equipped with a drain valve, and a filter screen is installed inside the drain valve;

[0010] The flocculation unit includes a flocculation chamber arranged horizontally inside the shell and above the cylindrical cavity, and a liquid dispersing assembly disposed inside the flocculation chamber. The left and right ends of the flocculation chamber are respectively provided with an inlet and an outlet. The outlet of the flocculation chamber is connected to the inlet of the cylindrical cavity through a filter assembly. An electronic valve is provided at the connection between the inlet and the filter assembly. The inlet at the left end of the flocculation chamber is connected to the algae liquid input end through a valve. The outlet at the left end of the cylindrical cavity is connected to the inlet at the left end of the flocculation chamber through a pipe and a pump.

[0011] Furthermore, both ends of the flocculation chamber and the adsorption unit are provided with a transmission disk assembly; the transmission disk assembly includes a second motor provided on the inner wall of the housing, a fixed disk provided at the output end of the second motor, a rotary motor embedded inside the fixed disk, and a limiting disk provided at the output end of the rotary motor.

[0012] Both the flocculation chamber and the cylindrical chamber are equipped with sliders for sliding using the algal liquid flow; the surface of the limiting plate is provided with a circular hole for adsorbing and fixing the slider; an electromagnet is provided in the circular hole, and a permanent magnet is provided on the slider.

[0013] Explanation: The rotary motor controls the limit plate to rotate, causing the slider to rotate to the inlet of the flocculation chamber and the cylindrical chamber. The algae solution flowing in from the inlet pushes the slider in the flocculation chamber, and the flocculated water flowing in from the inlet pushes the slider in the cylindrical chamber.

[0014] Furthermore, a plurality of first limiting grooves are provided at intervals on the inner sidewall of the flocculation chamber along the length direction of the flocculation chamber.

[0015] The liquid dispersing component includes multiple liquid bladders that are arranged one-to-one inside the first limiting groove, a first protrusion located at one end of the liquid bladder and on the side of the inlet of the flocculation chamber, and a pressure valve located at the bottom of the liquid bladder; the liquid bladder is filled with flocculant.

[0016] Explanation: The flow of algal liquid pushes the slider to slide, squeezing the liquid bladder to open the pressure valve and release the flocculant.

[0017] Furthermore, the filtration assembly includes a filter housing, a filter plate arranged horizontally inside the filter housing, an inlet pipe disposed at the bottom of the filter housing, an outlet pipe disposed at the top of the filter housing, and a drain valve pipe disposed at the bottom of the filter housing; the inlet pipe is connected to the outlet of the flocculation chamber, and the outlet pipe is connected to the inlet of the cylindrical chamber.

[0018] Explanation: The algae solution flowing out of the flocculation chamber enters through the inlet pipe, flows upward and emerges from the outlet pipe, causing impurities to settle below the filter plate, facilitating drainage through the drain valve.

[0019] Furthermore, each of the multiple sub-cavities is provided with an auxiliary component for controlling the opening of the compartment door by moving a slider; the auxiliary component includes a second protrusion located inside the sub-cavity, a straight rod rotatably disposed at the bottom of the second protrusion in a vertical direction, a gear plate fixedly disposed at the bottom of the straight rod, and a rack disposed at the bottom of the first box body and meshing with the gear plate;

[0020] The side wall of the opening is provided with a second limiting groove for supporting the second protrusion to slide along the length direction of the sub-cavity. The second protrusion is connected to one side of the opening by a return spring.

[0021] The door is a retractable baffle. One end of the door is fixedly connected to the opening side, and the other end of the door is connected to the second protrusion. The straight rod is equipped with stirring blades.

[0022] Explanation: The algae solution pushes the slider to slide inside the cylindrical cavity, causing the toothed disc at the bottom of the straight rod to rotate through the meshing action of the rack, which in turn drives the stirring blades to rotate, thus enhancing the filtration effect.

[0023] Furthermore, a first electric switch is provided at the connection between the first box and the interior of the cylindrical cavity, and a second electric switch is provided at the connection between the second box and the first box.

[0024] Note: The addition and discharge of filter media are controlled by opening and closing the first and second electric switches via the controller.

[0025] Furthermore, it also includes a cleaning and recycling unit, which is disposed at the inner bottom of the housing directly below the cylindrical cavity; the cleaning and recycling unit includes an ultrasonic cleaner disposed at the inner bottom of the housing and directly below the cylindrical cavity, a filter plate disposed laterally inside the ultrasonic cleaner, and a cleaning roller rotatably disposed on the inner sidewall of the ultrasonic cleaner; the surface of the cleaning roller is provided with a brush.

[0026] Explanation: The cleaning roller enhances the cleaning and recycling effect of the carbon nanotube-quartz sand filter media. The filter media is supported by the filter plate, causing floating objects to float to the top and sludge to fall to the bottom, thus achieving the separation of water, pollutants and filter media.

[0027] Furthermore, a transmission gear disc is fitted onto the cleaning roller, and the transmission gear disc is meshed with the gear ring via a synchronous belt;

[0028] The bottom of the filter plate is equipped with an air jet head that is connected to an air pump via a duct.

[0029] Explanation: The cleaning roller is rotated by a synchronous belt, and the filter material is cleaned by air through a jet nozzle connected to an air pump at the bottom of the filter plate, which accelerates the floating of floating objects.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] The device of this invention removes Microcystis aeruginosa using carbon nanotubes-quartz sand in the adsorption unit. The algal solution is discharged through the inlet of the flocculation chamber, allowing for controlled, incremental addition of untreated algal solution to ensure effective treatment. A flocculant is dispersed within the flocculation chamber via a dispersing component, and impurities flocculated from the algal solution are filtered by a filtration component. The filtered algal solution is then introduced into a cylindrical cavity, where a first motor controls rotation. The cylinder is then rotated via the tubes and pump. The algal solution circulates multiple times between the flocculation chamber and the cylindrical chamber for flocculation and filtration, enhancing the flocculation and filtration effect and increasing the residence time of the algal solution in the flocculation chamber and the cylindrical chamber. This allows the algal solution to repeatedly enter the sub-chamber and fully contact the carbon nanotube-quartz sand flowing out of the second chamber, effectively removing Microcystis aeruginosa from the algal solution. After algae removal is completed, the second electric switch and the drain valve are opened to allow the treated liquid to flow out. This effectively enhances the removal efficiency of Microcystis aeruginosa and achieves integrated flocculation and filtration. Attached Figure Description

[0047] The bottom of the second box 232 is equipped with a drain valve, and a filter screen is installed inside the drain valve;

[0048] Each of the multiple sub-cavities is equipped with an auxiliary component for controlling the opening of the compartment door by moving the slider 211; the auxiliary component includes a second protrusion 233 located inside the sub-cavity, a straight rod 234 rotatably disposed at the bottom of the second protrusion 233 along the vertical direction, a gear 235 fixedly disposed at the bottom of the straight rod 234, and a rack 236 disposed at the bottom of the first box 231 and meshing with the gear 235.

[0049] The side wall of the opening is provided with a second limiting groove for supporting the second protrusion 233 to slide along the length direction of the sub-cavity. The second protrusion 233 is connected to one side of the opening by a return spring 2331.

[0050] The door is a retractable baffle. One end of the door is fixedly connected to the opening side, and the other end of the door is connected to the second protrusion 233. A stirring blade is provided on the straight rod 234.

[0051] A first electric switch is provided at the connection between the first box 231 and the interior of the cylindrical cavity 21, and a second electric switch is provided at the connection between the second box 232 and the first box 231.

[0052] like Figure 5 As shown, the flocculation unit 3 includes a flocculation chamber 31 horizontally disposed inside the shell 1 and located above the cylindrical cavity 21, and a liquid dispersing component 32 disposed inside the flocculation chamber 31; the left and right ends of the flocculation chamber 31 are respectively provided with an inlet and an outlet; the outlet of the flocculation chamber 31 is connected to the inlet of the cylindrical cavity 21 through a filter component 33, and an electronic valve is provided at the connection between the inlet and the filter component 33; the inlet at the left end of the flocculation chamber 31 is connected to the algae liquid input end through a valve, and the outlet at the left end of the cylindrical cavity 21 is connected to the inlet at the left end of the flocculation chamber 31 through a pipe and a pump body; an electrically controlled valve is provided inside the pipe body;

[0053] When the fixed plate 342 moves, the electronic valve closes. When the round hole carrying the slider 211 reaches the water inlet of the cylindrical cavity 21, the slider 211 slides and engages with the water inlet of the cylindrical cavity 21, and the electronic valve opens to prevent algae liquid leakage.

[0054] like Figure 5 As shown, both ends of the flocculation chamber 31 and the adsorption unit 2 are provided with a transmission disk group 34; the transmission disk group 34 includes a second motor 341 provided on the inner wall of the housing 1, a fixed disk 342 provided at the output end of the second motor 341, a rotary motor embedded in the fixed disk 342, and a limiting disk 343 provided at the output end of the rotary motor.

[0055] Both the flocculation chamber 31 and the cylindrical chamber 21 are equipped with sliders 211 for sliding using the algal liquid flow; the surface of the limiting disk 343 is provided with a round hole for adsorbing and fixing the sliders 211; an electromagnet is provided on the round hole, and a permanent magnet is provided on the sliders 211.

[0056] The inner wall of the flocculation chamber 31 is provided with stripes with a height of 3mm extending along the length of the flocculation chamber 31, which can leave a gap between the slider 211 and the inner wall of the flocculation chamber 31, allowing a small amount of algal liquid to pass through. The inner wall of the cylindrical cavity 21 has the same diameter as the slider 211, and the movement of the slider 211 inside the cylindrical cavity 21 is a sealed sliding motion.

[0057] Several first limiting grooves are provided at intervals on the inner sidewall of the flocculation chamber 31 along the length direction of the flocculation chamber 31.

[0058] like Figure 6 As shown, the liquid dispersing component 32 includes multiple liquid bladders 321 that are correspondingly arranged inside the first limiting groove, a first protrusion 322 that is arranged at one end of the liquid bladder 321 and located on the side of the inlet of the flocculation chamber 31, and a pressure valve 323 that is arranged at the bottom of the liquid bladder 321; the liquid bladder 321 is filled with flocculant.

[0059] The tops of the first protrusion 322 and the second protrusion 233 are both made of hollow rubber material;

[0060] like Figure 7 As shown, the filter assembly 33 includes a filter housing 331, a filter plate 332 horizontally arranged inside the filter housing 331, an inlet pipe arranged at the bottom of the filter housing 331, an outlet pipe arranged at the top of the filter housing 331, and a drain valve pipe 333 arranged at the bottom of the filter housing 331; the inlet pipe is connected to the outlet of the flocculation chamber 31, and the outlet pipe is connected to the inlet of the cylindrical chamber 21.

[0061] like Figure 1 , 2 As shown, it also includes a cleaning and recycling unit 4, which is located at the bottom of the housing 1 directly below the cylindrical cavity 21. The cleaning and recycling unit 4 includes an ultrasonic cleaner 41 located at the bottom of the housing 1 and directly below the cylindrical cavity 21, a filter plate 42 horizontally disposed inside the ultrasonic cleaner 41, and a cleaning roller 43 rotatably disposed on the inner wall of the ultrasonic cleaner 41. The surface of the cleaning roller 43 is provided with a brush.

[0062] It should be noted that this embodiment also includes a power supply and a controller. The power supply, controller, first motor, second motor 341, electromagnet, permanent magnet, carbon nanotube-quartz sand, filter screen, liquid bladder 321, flocculant, filter plate 332, first electric switch, second electric switch, ultrasonic cleaner 41, filter plate 42, cleaning roller 43, jet head 421, and stirring blades are all commercially available products and will not be described in detail here. The pressure valve 323 is electrically connected to the controller, and the pressure valve is a commercially available threshold-controllable pressure valve.

[0063] The working principle of this embodiment is as follows: The inlet valve at the left end of the flocculation chamber 31 is opened, and algal solution is input from the algal solution input end. The algal solution impact slider 211 moves from left to right inside the flocculation chamber 31, pushing the first protrusion 322 to the right to squeeze the liquid bladder 321. The pressure inside the liquid bladder 321 increases, and flocculant is sprayed out from the pressure valve 323. After reaching the pressure threshold, the pressure valve 323 closes, and the first protrusion 322 stops sliding under the pressure of the liquid bladder 321. The algal solution impact slider 211 squeezes and deforms the first protrusion 322, thus moving forward past the first protrusion 322 to squeeze the subsequent liquid bladder 321 again. The algal solution is squeezed into the filter assembly 33 through the gap between the slider 211 and the inner wall of the flocculation chamber 31.

[0064] Turn on the electromagnet so that the circular hole attracts the slider 211. The limit plate 343 is rotated by the rotary motor. When the slider 211 is fully rotated to the water inlet of the cylindrical cavity 21, the electromagnet in the circular hole is disconnected and the electronic valve is opened so that the liquid in the filter assembly 33 pushes the slider 211 into the cylindrical cavity 21.

[0065] The cylindrical cavity 21 rotates continuously under the action of the second motor 341. After turning on the first electric switch and the second electric switch, the carbon nanotube-quartz sand inside the second box 232 flows into the multiple sub-cavities and the cylindrical cavity 21, and then the first electric switch and the second electric switch are turned off.

[0066] Slider 211 moves from right to left inside cylindrical cavity 21, pushing second protrusion 233 to compress return spring 2331 and slide to the left, causing the chamber door to fold open, allowing algal liquid to enter the opened sub-cavity. Second protrusion 233 slides, rack 236 drives toothed disc 235 to rotate, and stirring blades ensure that carbon nanotubes-quartz sand are fully mixed with algal liquid inside the sub-cavity. When algal liquid pushes second protrusion 233 to near rest, the top of second protrusion 233 deforms. Under the pressure of algal liquid, slider 211 passes over second protrusion 233 and pushes the next second protrusion 233 to the left. 33. When the slider 211 moves to the leftmost end of the cylindrical cavity 21, the electromagnet in the left end round hole is turned on, so that the slider 211 is attracted into the round hole. The slider 211 is moved to the inlet of the flocculation cavity 31 to complete the cyclic movement of the slider 211. The algae liquid is squeezed out of the cylindrical cavity 21 by the slider 211. The pump is turned on to send the algae liquid into the left end inlet of the flocculation cavity 31, so that the algae liquid circulates and flocculates between the flocculation cavity 31 and the cylindrical cavity 21. After the algae removal is completed, the second electric switch and the drain valve are turned on, so that the treated algae liquid flows into the cleaning and recovery unit 4 through the filter screen for filtration and cleaning.

[0067] Example 2

[0068] The difference between this embodiment and Embodiment 1 is that, Figure 8 As shown, a transmission gear plate 431 is sleeved on the cleaning roller 43, and the transmission gear plate 431 is connected to the gear ring 24 by a synchronous belt 432.

[0069] The bottom of the filter plate 42 is provided with an air jet head 421 that is connected to the air pump via a duct.

[0070] The working principle of this embodiment is as follows: the cleaning roller 43 is driven to rotate by the synchronous belt 432, and the filter material is cleaned by gas through the air nozzle 421 connected to the air pump at the bottom of the filter plate 42, which accelerates the floating of floating objects.
