Description

Technical Field

[0001] This invention relates to the field of wastewater treatment equipment technology, specifically to a hydroxyl radical generating device and an organic wastewater treatment system. Background Technology

[0002] Hydroxyl radicals possess extremely strong oxidizing properties and can rapidly destroy cell tissues, thus finding widespread application in wastewater treatment. Among various hydroxyl radical generation devices, centrifugal beds are widely used due to their high hydroxyl radical generation efficiency. For example... Figure 1 As shown, it includes a body 100, which has a reaction chamber 110, an air inlet 120, an air outlet 130, a liquid inlet 140, and a liquid outlet 150. A rotor 200 is installed inside the reaction chamber 110, and a catalyst is installed on the rotor 200. The power input shaft of the rotor 200 is connected to the power output shaft of the drive motor 300.

[0003] However, as the reaction proceeds, the catalyst mounted on the rotor may become less efficient or even fail due to the adhesion of dirt. Furthermore, in the existing hydroxyl radical generating apparatus described above, cleaning the catalyst requires removing the entire rotor from the reaction chamber, which is cumbersome and inconvenient for cleaning the catalyst on the rotor. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the purpose of this invention is to provide a hydroxyl radical generating device and an organic wastewater treatment system to solve or alleviate the above-mentioned technical problems existing in the prior art.

[0008] A locking component is disposed on the catalyst carrier and the rotor body. The locking component has a lockable state and an unlocked state that can be switched between each other. When the locking component is in the locked state, it locks the catalyst carrier so that the catalyst carrier cannot be separated from the rotor body. When the locking component is in the unlocked state, it releases the lock on the catalyst carrier so that the catalyst carrier can be separated from the rotor body.

[0009] Furthermore, it also includes a cleaning component, which comprises:

[0010] A cleaning tank, wherein a window is provided on one side of the machine body for the catalyst carrier to enter and exit, and the cleaning tank is disposed at the window and fixedly connected to the machine body; and

[0011] An ultrasonic cleaner, which is housed within the machine body; and

[0012] The gripping component is used to grip the target catalyst carrier and transfer it to the target location.

[0013] Furthermore, the grasping component includes:

[0014] A gripping arm has a first end extending into the cleaning tank and a second end extending out of the cleaning tank. The gripping arm is slidably connected to the cleaning tank so that the gripping arm can reciprocate between a first position and a second position along the radial direction of the rotor. When the gripping arm is in the first position, the first end of the gripping arm is located inside the cleaning tank, and when the gripping arm is in the second position, the first end of the gripping arm is located inside the reaction chamber.

[0015] A first drive structure is used to drive the gripping arm to move from a first position to a second position or from a second position to a first position;

[0020] A first nut is sleeved on the first lead screw and drivenly connected to the first lead screw so that when the first lead screw rotates, it can drive the first nut to move along the axis of the first lead screw. The first nut is fixedly connected to the gripping arm so that the first nut can move together with the gripping arm; and

[0021] A first motor is fixedly connected to the machine body, and the power output shaft of the first motor is connected to the first lead screw to drive the first lead screw to rotate in the forward or reverse direction.

[0022] Furthermore, the second driving structure includes:

[0023] The second lead screw is disposed at the first end of the gripping arm. The second lead screw is rotatably connected to the gripping arm and is drively connected to the two gripping elements.

A locking hole adapted to the locking element is correspondingly opened on the side wall of the catalyst carrier. When the locking element is in the locked position, the locking element can be inserted into the locking hole to lock the locking assembly. When the locking element is in the unlocked position, the locking element is located outside the locking hole to unlock the locking assembly.

[0030] The third drive structure is used to drive the locking element to move from the locked position to the unlocked position or from the unlocked position to the locked position.

[0031] Furthermore, the third driving structure includes:

[0032] A slider is disposed within the rotor body.

[0034] The second permanent magnet is fixedly embedded in the gripping element, and the magnetic properties of the opposite sides of the first permanent magnet and the second permanent magnet are the same.

[0035] An elastic element has its two ends connected to the slider and the rotor body, respectively. In its natural state, the elastic element applies a spring force to the slider so that the slider tends to move from the fourth position to the third position.

Detailed Implementation

[0056] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0057] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0058] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0059] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly defined.

[0060] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0061] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0062] like Figure 1 As shown, a hydroxyl radical generating device includes a body 100, a rotor 200, and a drive motor 300.

[0063] The machine body 100 has a reaction chamber 110 and an air inlet 120, an air outlet 130, a liquid inlet 140 and a liquid outlet 150 communicating with the reaction chamber 110. The rotor 200 is disposed in the reaction chamber 110 and is rotatably connected to the machine body 100. The drive motor 300 is fixedly connected to the machine body 100, and the power output shaft of the drive motor 300 is drively connected to the power input shaft of the rotor 200.

[0064] In use, ozone enters the reaction chamber 110 through the air inlet 120, while water enters the rotor 200 through the liquid inlet 140. As the rotor 200 rotates at high speed, the water is pushed to the outer edge of the rotor 200 by the centrifugal force generated by the high-speed rotation. During this process, the liquid is continuously dispersed and broken by the rotor 200, forming tiny droplets, liquid filaments and liquid films, increasing the gas-liquid contact area. After the mass transfer or reaction is completed, the liquid flows out from the outer edge of the rotor 200 and enters the collection area of ​​the shell, and finally is discharged from the liquid outlet 150. The remaining gas is discharged from the gas outlet 130.

[0065] However, the aforementioned hydroxyl radical generating device is not convenient for cleaning the catalyst on the rotor 200, therefore, as Figure 2 As shown, in this embodiment, the rotor 200 of the hydroxyl radical generating device includes a rotor body 210, a catalyst carrier 220, and a locking component.

[0066] The rotor body 210 is disposed inside the reaction chamber 110 and is rotatably connected to the machine body 100. The outer side wall of the rotor body 210 is provided with multiple mounting ports, which are evenly arranged around the rotation center line of the rotor body 210 so that the rotor 200 can generate a relatively uniform moment of inertia when rotating.

[0067] The catalyst carrier 220 is provided with a catalyst. The catalyst carrier 220 corresponds one-to-one with the mounting port, and the catalyst carrier 220 is set at the mounting port.

[0068] A locking assembly is disposed on the catalyst carrier 220 and the rotor body 210. The locking assembly has a lockable position and an unlocked position that can be switched between each other. When the locking assembly is in the locked state, it locks the catalyst carrier 220 so that the catalyst carrier 220 cannot be separated from the rotor body 210. When the rotor body 210 rotates, the catalyst carrier 220 can rotate with the rotor body 210 without separating from it under the action of centrifugal force. When the locking assembly is in the unlocked state, it releases the lock on the catalyst carrier 220, allowing the catalyst carrier 220 to be separated from the rotor body 210.

[0069] like Figure 3-8 As shown, in this embodiment, the hydroxyl radical generating device further includes a cleaning component and a gripping component.

[0070] The cleaning assembly includes a cleaning tank 410 and an ultrasonic cleaner 420.

[0071] The machine body 100 has a window on one side for the catalyst carrier 220 to enter and exit. A cleaning tank 410 is located at the window and is fixedly connected to the machine body 100. The cleaning tank 410 has a cleaning liquid inlet 411 and a cleaning liquid outlet 412. The cleaning liquid inlet 411 is connected to and communicates with a cleaning liquid supply pipe, and the cleaning liquid outlet 412 is connected to and communicates with a drain pipe. An ultrasonic cleaner 420 is installed inside the cleaning tank 410.

[0072] During cleaning, a preset volume of cleaning fluid is supplied to the cleaning tank 410 through the cleaning fluid supply pipe, and the ultrasonic cleaner 420 is started to clean the catalyst carrier 220. After cleaning, the cleaning fluid in the cleaning tank 410 is discharged from the drain pipe.

[0073] The gripping component is used to grip the target catalyst carrier 220 and transfer it to the target location. Specifically, during cleaning, the gripping component grips the target catalyst carrier 220 and transfers it into the cleaning tank 410 for cleaning; after cleaning, the gripping component transfers the target catalyst carrier 220 to the corresponding mounting port and places it at the mounting port.

[0074] Specifically, during use, when the catalyst carrier 220 needs to be cleaned, the drive motor 300 rotates the target catalyst carrier 220 to the window. The gripping component extends into the reaction chamber 110 from the window and grips the target catalyst carrier 220. At the same time, the locking component switches to the unlocked state, thereby releasing the lock on the catalyst carrier 220. Afterwards, the gripping component moves the catalyst carrier 220 out of the window and transfers it to the cleaning tank 410.

[0075] A preset volume of cleaning fluid is supplied to the cleaning tank 410 through the cleaning fluid supply pipe, and the ultrasonic cleaner 420 is started to clean the catalyst carrier 220. After cleaning, the cleaning fluid in the cleaning tank 410 is discharged from the drain pipe. The catalyst carrier 220 is then transferred to the corresponding mounting port by the gripping component and placed there. At the same time, the locking component switches to the locked state, thereby locking the catalyst carrier 220.

[0076] The hydroxyl radical generating device provided in this embodiment achieves automatic catalyst cleaning by setting up a gripping component and a cleaning component. It is simple to operate and highly efficient.

[0077] like Figure 4 , 6 As shown, preferably, a position sensor 710 is fixedly installed on the inner wall of the reaction chamber. The position sensor 710 is electrically connected to the controller. A sensing plate 720 corresponding to the position sensor 710 is installed on the outer wall of the rotor body 210, with each sensing plate 720 corresponding to a mounting port. During cleaning, when the position sensor 710 senses the corresponding sensing plate 720, it indicates that the catalyst carrier 220 corresponding to that sensing plate has moved to the cleaning station, thereby achieving precise positioning of the catalyst carrier 220. Meanwhile, preferably, the drive motor 300 is a servo motor.

[0078] like Figure 4 , 6 As shown, the gripping assembly includes a gripping arm 510, a first drive structure, a gripping element 530, and a second drive structure.

[0079] The gripping arm 510 has a first end extending into the cleaning tank 410 and a second end extending out of the cleaning tank 410. The gripping arm 510 is slidably connected to the cleaning tank 410, allowing it to reciprocate between a first position and a second position along the radial direction of the rotor 200. Specifically, the gripping arm 510 has a first position and a second position that can be switched between each other. When the gripping arm 510 is in the first position, its first end is located inside the cleaning tank 410; when it is in the second position, its first end is located inside the reaction chamber 110. The connection between the sidewall of the gripping arm 510 and the cleaning tank 410 remains sealed. A first drive structure is used to drive the gripping arm 510 to move from the first position to the second position or from the second position to the first position.

[0080] Two gripping elements 530 are provided, symmetrically arranged at the first end of the gripping arm 510. Both gripping elements 530 are slidably connected to the gripping arm 510, allowing them to move closer or further apart. That is, the two gripping elements 530 have interchangeable gripping and release positions. When in the gripping position, the distance between the two gripping elements 530 is relatively small; when in the release position, the distance between them is relatively large. A second driving structure is used to drive the two gripping elements 530 to move closer or further apart.

[0081] When cleaning the catalyst carrier 220, firstly, the first drive structure drives the gripping arm 510 from the first position to the second position so that the gripping arm 510 extends into the reaction chamber 110; then, the second drive structure drives the two gripping elements 530 to move from the release position to the gripping position so as to grip the catalyst carrier 220; then, the first drive structure drives the gripping arm 510 from the second position to the first position so that the gripping arm 510 carries the catalyst carrier 220 into the cleaning tank 410.

[0082] After cleaning, firstly, the first drive structure drives the gripping arm 510 from the first position to the second position to move the catalyst carrier 220 to the corresponding mounting port; then, the second drive structure drives the two gripping elements 530 from the gripping position to the release position, thereby releasing the catalyst carrier 220; then, the first drive structure drives the gripping arm 510 from the second position to the first position to move the gripping arm 510 outside the reaction chamber 110.

[0083] In some embodiments, the first drive structure includes a telescopic device (not shown in the figures), which may be one of an electric actuator, a pneumatic cylinder, a hydraulic cylinder, or an electro-hydraulic actuator. The power output shaft of the telescopic device is drively connected to the gripping arm 510. When the telescopic device extends, it drives the gripping arm 510 to move from a first position to a second position; when the telescopic device retracts, it drives the gripping arm 510 to move from the second position to the first position.

[0084] However, the first drive structure described above occupies a relatively large space in order to ensure sufficient drive distance. Therefore, as... Figure 4 As shown, in this embodiment, the first drive structure includes a first lead screw 521, a first nut 522, and a first motor 523.

[0085] The first lead screw 521 is rotatably connected to the machine body 100. The first nut 522 is sleeved on the first lead screw 521 and is driven by the first lead screw 521, so that when the first lead screw 521 rotates, it can drive the first nut 522 to move along the axis of the first lead screw 521. The first nut 522 is fixedly connected to the gripping arm 510, so that the first nut 522 can move along with the gripping arm 510. The first motor 523 is fixedly connected to the machine body 100, and the power output shaft of the first motor 523 is driven by the first lead screw 521, so as to drive the first lead screw 521 to rotate in the forward or reverse direction. Specifically, when the first motor 523 drives the first lead screw 521 to rotate in the forward direction, it drives the gripping arm 510 to move from the first position to the second position via the first nut 522; when the first motor 523 drives the first lead screw 521 to rotate in the reverse direction, it drives the gripping arm 510 to move from the second position to the first position via the first nut 522.

[0086] Specifically, a mounting box 550 is fixedly connected to the side of the cleaning tank 410 away from the rotor 200, and the first lead screw 521, the first nut 522 and the first motor 523 are arranged inside the mounting box 550.

[0087] The first driving structure provided in this embodiment is simple in structure and occupies less space while ensuring sufficient driving distance.

[0088] In some embodiments, the second drive structure includes two telescopic devices (not shown in the figures), which may be one of a cylinder, an electric actuator, a hydraulic cylinder, or an electro-hydraulic actuator. The power output shafts of the two telescopic devices are respectively connected to two gripping elements 530 to drive the two gripping elements 530 to move closer or further apart.

[0089] However, the second drive structure described above, due to the telescopic device itself having a moving length and the need to ensure a driving distance, occupies a relatively large space. Therefore, as... Figure 4 , 6As shown, in this embodiment, the second drive structure includes a second lead screw 541, a drive shaft 542, a first bevel gear 543, a second bevel gear 544, and a second motor 545.

[0090] The second lead screw 541 is disposed at the first end of the gripping arm 510 and is rotatably connected to the gripping arm 510. The second lead screw 541 is drivenly connected to two gripping elements 530, and when the second lead screw 541 rotates, the two gripping elements 530 move closer to or further away from each other. Specifically, the circumferential wall of the second lead screw 541 is provided with two external threads of the same pitch but opposite directions. The second lead screw 541 is drivenly connected to the two gripping elements 530 respectively through the two external threads. When the second lead screw 541 rotates in the forward direction, the two gripping elements 530 move closer to each other, and when the second lead screw 541 rotates in the reverse direction, the two gripping elements 530 move further away from each other.

[0091] The drive shaft 542 is rotatably connected to the gripping arm 510. A first bevel gear 543 is coaxially sleeved on the second lead screw 541 and is drive-connected to the second lead screw 541. A second bevel gear 544 is coaxially sleeved on the drive shaft 542 and is drive-connected to the drive shaft 542; the second bevel gear 544 meshes with the first bevel gear 543. A second motor 545 is fixedly mounted on the gripping arm 510, and the power output shaft of the second motor 545 is drive-connected to the drive shaft 542.

[0092] In operation, the second motor 545 drives the drive shaft 542 to rotate, the drive shaft 542 drives the second bevel gear 544 to rotate, the second bevel gear 544 drives the first bevel gear 543 to rotate, and the first bevel gear 543 drives the second lead screw 541 to rotate. This, in turn, drives the two gripping elements 530 to move closer or further apart via the second lead screw 541. Specifically, when the second motor 545 drives the drive shaft 542 to rotate in the forward direction, the two gripping elements 530 move closer together; when the second motor 545 drives the drive shaft 542 to rotate in the reverse direction, the two gripping elements 530 move further apart.

[0093] The second drive structure provided in this embodiment is simple in structure, reasonable in design, and saves space.

[0094] like Figure 4 , 5 As shown in Figures 6 and 7, the locking assembly includes a locking element 231 and a third drive structure.

[0095] A locking element 231 is disposed within the rotor body 210 and is slidably connected to the rotor body 210, allowing the locking element 231 to have switchable locked and unlocked positions. A locking socket 221, adapted to the locking element 231, is correspondingly provided on the side wall of the catalyst carrier 220. When the locking element 231 is in the locked position, it can be inserted into the locking socket 221, thus locking the assembly; when the locking element 231 is in the unlocked position, it is located outside the locking socket 221, thus unlocking the assembly.

[0096] The third driving structure is used to drive the locking element 231 from the locked position to the unlocked position or from the unlocked position to the locked position. Specifically, when it is necessary to unlock the catalyst carrier 220, the third driving structure drives the locking element 231 from the locked position to the unlocked position, so that the locking element 231 moves out of the locking socket 221, thereby achieving the purpose of unlocking the catalyst carrier 220; when it is necessary to lock the catalyst carrier 220, the third driving structure drives the locking element 231 from the unlocked position to the locked position, so that the locking element 231 is located in the locking socket 221, thereby achieving the purpose of locking the catalyst carrier 220.

[0097] like Figure 4 , 5 As shown in Figures 6 and 7, the third driving structure includes a slider 232, a first permanent magnet 233, a second permanent magnet 234, an elastic element 235, and a driving block 236.

[0098] A slider 232 is disposed within the rotor body 210, and a locking element 231 is fixedly connected to the slider 232. The slider 232 is slidably connected to the rotor body 210, allowing the slider 232 to have a third position and a fourth position that can be switched between each other. Specifically, when the slider 232 is in the third position, the locking element 231 is in the locked position; when the slider 232 is in the fourth position, the locking element 231 is in the unlocked position. A first permanent magnet 233 is fixedly embedded in the slider 232. A second permanent magnet 234 is fixedly embedded in the gripping element 530, and the magnetic properties of opposite sides of the first permanent magnet 233 and the second permanent magnet 234 are identical, so that when the first permanent magnet 233 and the second permanent magnet 234 are aligned, a magnetic repulsive force is generated between them, thereby driving the slider 232 from the third position to the fourth position. The two ends of the elastic element 235 are connected to the slider 232 and the rotor body 210, respectively. In its natural state, the elastic element 235 applies a spring force to the slider 232, causing the slider 232 to tend to move from the fourth position to the third position. The drive block 236 is disposed on the side of the catalyst carrier 220 facing the axis of the rotor 200. The drive block 236 is fixedly connected to the catalyst carrier 220, and the side of the drive block 236 facing the axis of the rotor body 210 is provided with a drive ramp 201 that cooperates with the locking element 231.

[0099] During gripping, the gripping element 530 extends into the rotor body 210, thereby aligning the second permanent magnet 234 with the first permanent magnet 233. Under the action of the magnetic repulsion between the first permanent magnet 233 and the second permanent magnet 234, the slider 232 is driven from the third position to the fourth position, and the slider 232 drives the locking element 231 to move from the locked position to the unlocked position.

[0100] During the process of transferring the catalyst carrier 220 to the mounting port, the drive block 236 applies a force to the locking element 231 through the drive ramp 201, so that the locking element 231 overcomes the elastic force of the elastic element 235 and moves from the locked position to the unlocked position, so that the locking element 231 does not affect the movement of the catalyst carrier 220.

[0101] like Figure 3 , 4 As shown, in this embodiment, the hydroxyl radical generating device further includes a gate 610 and a fourth driving device 620.

[0102] A door 610 is positioned at the window and is used to block the window. The door 610 is slidably connected to the main body so that it has an open position and a blocked position that can be switched between each other. When the door 610 is in the open position, it opens the window so that the drive assembly can extend into the reaction chamber 110. When the door 610 is in the blocked position, it closes the window so that water in the reaction chamber 110 will not enter the cleaning tank 410 during the reaction process.

[0103] The fourth drive device 620 is fixedly connected to the body 100. The fourth drive device 620 is used to drive the door 610 from the blocked position to the open position or from the open position to the blocked position. Specifically, the fourth drive device 620 is a telescopic rod, which can be one of an electric push rod, an electro-hydraulic push rod, a pneumatic cylinder, or a hydraulic cylinder. The power output shaft of the telescopic rod is connected to the door 610 to drive the door 610 to move.

[0105] The liquid outlet of the treatment tank 2 is connected to the liquid inlet of the hydroxyl radical generating device 1, and the liquid inlet of the treatment tank 2 is connected to the liquid outlet of the hydroxyl radical generating device 1. The ozone generation system includes an oxygen tank 31 and an ozone generator 32. The gas outlet of the oxygen tank 31 is connected to the gas inlet of the ozone generator 32, and the gas outlet of the ozone generator 32 is connected to the gas inlet of the hydroxyl radical generating device 1.

[0106] In use, oxygen from oxygen tank 31 enters ozone generator 32. Under the action of ozone generator 32, oxygen reacts to generate ozone, which then enters hydroxyl radical generating device 1. Wastewater from treatment tank 2 enters hydroxyl radical generating device 1 under the action of water pump, where it reacts with ozone to generate hydroxyl radicals. The hydroxyl radicals oxidize the organic matter in the wastewater, thereby achieving the purpose of purifying the wastewater.

[0107] Preferably, an ozone detector 4 is installed on the air inlet pipe and the air outlet pipe.

[0108] like Figure 10 As shown, in one embodiment, the present invention also provides an organic wastewater treatment system, including a treatment tank 2, an ozone generation system, and a hydroxyl radical generating device 1 as described in any of the above embodiments.

[0109] The treatment tank 2 is connected to the outlet of the hydroxyl radical generating device 1 and the wastewater supply system. The ozone generating system includes an oxygen tank 31 and an ozone generator 32. The outlet of the oxygen tank 31 is connected to the inlet of the ozone generator 32, and the outlet of the ozone generator 32 is connected to the inlet of the hydroxyl radical generating device 1.

[0110] During operation, wastewater is fed into treatment tank 2. Simultaneously, oxygen from oxygen tank 31 enters ozone generator 32. Under the action of ozone generator 32, the oxygen reacts to generate ozone, which then enters hydroxyl radical generating device 1. The ozone in hydroxyl radical generating device 1 reacts with water or hydrogen peroxide to generate hydroxyl radicals. The generated hydroxyl radicals are then fed into treatment tank 2, where they react with the wastewater to achieve the purpose of wastewater treatment.
