Description

Technical Field

[0001] This utility model belongs to the field of optical components, systems or instruments, and specifically relates to a photoelectric hybrid dual-path power supply device applied in photoelectrocatalytic equipment. Background Technology

[0002] See the existing publication (announcement) document CN104069786A, which discloses a photoelectrocatalytic reaction device and a method for treating organic polluted wastewater. Photocatalytic oxidation treatment of organic polluted wastewater has the characteristics of mild reaction conditions, strong oxidation capacity, no secondary pollution and wide applicability, and is a very promising wastewater treatment technology.

[0003] The aforementioned device uses a large piece of sponge nickel mesh bent into a curved shape and placed close to the inner wall of the beaker as the anode of the motor, and a small piece of sponge nickel metal mesh as the counter electrode. The positive and negative terminals of the regulated DC power supply are connected to the anode and counter electrode of the motor, respectively. The ultraviolet lamp is placed in the center of the beaker, and the aeration head is tied to the lamp tube of the ultraviolet lamp. The aeration head is connected to an oxygenation pump to supply oxygen in the form of aeration. The beaker is placed on a magnetic stirrer to keep it stirred.

[0004] See the existing publication (announcement) document CN117019230A, which discloses a carbon nitride-based supported photocatalytic material and its device for combined photocatalytic oxidation of wastewater. The device directly electrocatalytically oxidizes organic pollutants in wastewater at the anode, while the cathode electrocatalyzes the conversion of oxygen-containing gas introduced through the aeration port into hydrogen peroxide and hydroxyl radicals. In the photocatalytic chamber, the carbon nitride-based supported photocatalytic material further converts the hydrogen peroxide not fully utilized by the cathode into hydroxyl radicals through photocatalysis, thereby achieving photocatalytic synergy and completing the efficient catalytic oxidation of wastewater.

[0005] Both of the aforementioned devices are equipped with aeration heads / inlets, through which oxygen is introduced. Oxygen acts as an electron acceptor in the photocatalytic reaction, promoting the separation of electrons and holes and reducing their recombination, thereby improving the efficiency of the photocatalytic reaction. Secondly, oxygen can be activated during photocatalysis to transform into highly reactive hydroxyl radicals (OH). These radicals possess extremely strong oxidizing power and can effectively mineralize organic pollutants. Furthermore, the oxygen introduced through aeration increases the dissolved oxygen concentration in the water, providing the necessary oxidant for electrocatalytic oxidation and enhancing the oxidizing capacity of the electrocatalytic reaction. However, the lack of a stirring device in these devices to ensure uniform mixing of oxygen in the water leads to low oxygen solubility. Without stirring to help disperse it, oxygen tends to accumulate in localized areas, forming enriched zones, while other areas may experience insufficient oxygen supply, reducing the efficiency of the photocatalytic reaction. Secondly, the generation of hydroxyl radicals depends on the uniform activation of oxygen; uneven oxygen distribution limits the formation of hydroxyl radicals in the water, reducing their ability to oxidize and degrade organic pollutants. Utility Model Content

[0006] The purpose of this invention is to provide a photoelectric hybrid dual-path power supply device for use in photoelectrocatalytic equipment, in order to solve the problem of uneven oxygen distribution in the prior art.

[0007] To achieve the above objectives, this solution provides a photoelectric hybrid dual-path power supply device for use in photoelectrocatalysis equipment, including a reactor dish and a regulated DC power supply. The regulated DC power supply provides power to the device. An ultraviolet lamp is installed above the reactor dish, and an electrode anode and a photocatalytic chamber are installed inside the reactor dish. The device also includes:

[0008] A drive rod, one end of which is rotatably connected to the bottom of the reactor dish, and the motor anode and photocatalytic chamber are both mounted on the drive rod;

[0009] The motor, the output end of which is fixedly connected to the drive rod.

[0010] The principle of this scheme is as follows: oxygen in the photocatalytic chamber is discharged from the chamber column after photocatalysis. A motor drives a drive rod to rotate, which in turn causes the photocatalytic chamber on the drive rod to rotate the chamber column, thus causing the oxygen discharged from the chamber column to be thrown further out under centrifugal force. Simultaneously, the rotation of the photocatalytic chamber agitates the water, resulting in a more uniform distribution of oxygen in the water.

[0011] The advantages of this scheme are: (1) By driving the drive rod connected to the bottom of the reactor vessel to rotate via a motor, the photocatalytic chamber and the chamber column are rotated. Centrifugal force is used to discharge the oxygen generated by photocatalysis from the chamber column and throw it further, increasing the contact area between oxygen and water. At the same time, the rotation of the photocatalytic chamber agitates the water, further promoting the mixing and diffusion of oxygen in the water, and achieving uniform oxygen distribution. (2) Compared with the static aeration in the existing technology, this scheme reduces the problem of local oxygen oversaturation or deficiency, and avoids the problem of low photocatalytic efficiency caused by uneven oxygen distribution.

[0012] Furthermore, the drive rod is a bidirectional screw, and the drive rod is threadedly connected to a left-handed first slider, and the photocatalytic chamber is fixedly mounted on the first slider.

[0013] The principle and effect of this scheme are as follows: (1) The motor drives the drive rod to rotate, thereby causing the first slider to rotate and rise or fall, thereby driving the photocatalytic chamber to rotate and rise or fall, so that the lower and upper layers of water can be stirred when stirring the water. (2) By rotating the spiral of the photocatalytic chamber to rise or fall, different water layers are stirred, thereby promoting the photocatalytic reaction more evenly when stirring the water and improving the treatment efficiency.

[0014] Furthermore, the drive rod is threadedly connected to a second slider that rotates to the right, and the motor anode is fixedly mounted on the second slider.

[0015] The principle and effect of this scheme are as follows: (1) The second slider is set to drive the motor anode and the photocatalytic chamber to rotate in opposite directions, so that the motor anode and the photocatalytic chamber stir the upper and lower layers of water respectively. (2) Since the water will generate bubbles during the stirring process and float on the surface of the water layer, affecting the photocatalytic effect, the second slider rotates to the right to drive the motor anode to move to the surface of the water, thereby breaking the bubbles on the surface.

[0016] Furthermore, the motor is a speed-regulating motor, and the motor is electrically connected to a controller.

[0017] The principle and effect of this solution is to control the rotational speed of the drive rod through a speed-regulating motor.

[0018] Furthermore, the photocatalytic chamber is provided with a photocatalytic support plate, the photocatalytic support plate is provided with a lamp source and an aeration port, the photocatalytic support plate is provided with a cleaning component, the cleaning component includes a cleaning block and a driving unit for driving the cleaning block, the cleaning block is configured to cooperate with the aeration port.

[0019] The principle and effect of this scheme are as follows: (1) Since the light blowing studio is located in the water body, impurities in the water will enter and block the aeration port. Therefore, a cleaning component is set up to clean the aeration port. (2) The cleaning block is driven to move towards the aeration port by the drive unit, so that the cleaning block is inserted into the aeration port to clean the impurities accumulated in the aeration port.

[0020] Furthermore, the driving unit includes a movable plate and a driving block. The cleaning block is disposed on the movable plate, and the driving block is connected to a spring. The other end of the spring is fixedly connected to the photocatalytic support plate. The driving block is used to abut against the movable plate to move it upward.

[0021] The principle and effect of this scheme are as follows: (1) When the motor speed is relatively fast, the drive block is thrown out of the rotation center by a large centrifugal force and moves to the maximum stroke, thereby pushing the movable plate and the cleaning block to move upward, and thus cleaning the aeration port. When the motor speed is relatively slow, the drive block is reset by a small centrifugal force, and the movable plate resets under its own gravity after losing the resistance of the drive block, thereby moving the cleaning block away from the aeration port. (2) The change of centrifugal force allows the cleaning block to be periodically inserted into the aeration port to clean the aeration port, and at the same time as the centrifugal force changes, the oxygen discharged from the chamber column can be thrown further, so that the oxygen comes into contact with the water layer by layer, thereby improving the uniform mixing of oxygen and water.

[0022] Furthermore, the surface of the drive block that contacts the movable plate is an inclined surface, and the height of the inclined surface is not less than the distance between the movable plate and the aeration port.

[0023] The principle and effect of this solution are as follows: through the two inclined surfaces of the drive block and the movable plate, when the drive block moves to its maximum stroke under centrifugal force, it can use the inclined surfaces to push the movable plate upward to its maximum stroke, thereby inserting the cleaning block into the aeration port for cleaning.

[0024] Furthermore, the photocatalytic support plate has a sliding groove and a recess, the driving block is slidably connected to the sliding groove, and the movable plate is slidably connected to the recess.

[0025] The principle and effect of this solution are as follows: the chute and groove provide positioning and guidance for the movement of the drive block and the movable plate, respectively.

[0026] Furthermore, a tension spring is provided inside the movable plate.

[0027] The principle and effect of this solution is to facilitate the resetting of the movable plate.

[0028] Furthermore, the structure of the cleaning block is compatible with the aeration port, and the outer wall of the cleaning block is provided with a rubber coating.

[0029] The principle and effect of this solution is to enable the cleaning block to better remove dirt from the aeration port and keep the aeration port unobstructed. Attached Figure Description

[0034] The following will describe the concept and technical effects of this utility model clearly and completely with reference to the embodiments, so as to fully understand the purpose, features and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model.

[0035] Please see Figure 2A photoelectric hybrid dual-path power supply device for use in photoelectrocatalysis equipment includes a reactor dish 1 and a regulated DC power supply. The regulated DC power supply provides electrical energy to the device. An ultraviolet lamp (not shown in the figure) is installed above the reactor dish 1. A drive rod 4, which is a bidirectional screw, is rotatably installed inside the reactor dish 1. One end of the drive rod 4 extends to the bottom of the reactor dish 1 and is connected to a motor 5. The motor 5 is a servo motor and is electrically connected to a PID controller. A left-handed first slider 41 and a right-handed second slider 42 are threadedly connected to the drive rod 4. A photocatalytic chamber 3 is installed on the first slider 41, and a motor anode 2 is installed on the second slider 42. Oxygen in the photocatalytic chamber 3 is discharged from the chamber column after photocatalysis. The motor 5 drives the drive rod to rotate, causing the first slider 41 to rotate and rise or fall, which in turn drives the photocatalytic chamber 3 to rotate and rise or fall. This agitates both the upper and lower layers of water during stirring. The second slider 42 drives the motor anode 2 to rotate in the opposite direction to the photocatalytic chamber 3, allowing the motor anode 2 and the photocatalytic chamber 3 to stir the upper and lower layers of water respectively. The spiral rotation of the photocatalytic chamber 3 and the motor anode 2, rising or falling, agitates different water layers, thus promoting the photocatalytic reaction more evenly and improving treatment efficiency. Simultaneously, the rotation of the photocatalytic chamber 3 agitates the water, resulting in a more uniform distribution of oxygen in the water.

[0036] Please see Figure 3The photocatalytic chamber 3 contains a photocatalytic support plate 31, on which a lamp source and an aeration port 311 are mounted. A cleaning component 6 is also located within the photocatalytic support plate 31. The cleaning component 6 includes a cleaning block 61 and a drive unit 62 for driving the cleaning block 61. The structure of the cleaning block 61 fits into the aeration port 311. The outer wall of the cleaning block 61 has a rubber coating, allowing it to better remove dirt from the aeration port and keep it unobstructed. The drive unit 62 includes a movable plate 621 and a drive block 622. A tension spring 624 is located within the movable plate 621 to assist in its repositioning. The cleaning block 61 is mounted on the movable plate 621. A spring 623 is connected to the drive block 622, and the other end of the spring 623 is connected to the photocatalytic... The support plate 31 is fixedly connected, and the surface of the drive block 622 that contacts the movable plate 621 is inclined, so that when the drive block 622 moves to its maximum stroke under centrifugal force, it can use the inclined surface to push the movable plate 621 upward to its maximum stroke, thereby inserting the cleaning block 61 into the aeration port 311 for cleaning. The height of the inclined surface is not less than the distance between the movable plate 621 and the aeration port 311. A sliding groove 312 is provided in the photocatalytic support plate 31, and the drive block 622 is slidably connected to the sliding groove 312. The sliding groove 312 provides positioning and guidance for the movement of the drive block 622. A groove 313 is also provided in the photocatalytic support plate 31, and the movable plate 621 is slidably connected to the groove 313. The groove 313 provides a limiting function for the up and down movement of the movable plate 621. When the motor 5 rotates at a high speed, the drive block 622 is thrown out of the center of rotation by a large centrifugal force and moves to its maximum stroke, thereby pushing the movable plate 621 and the cleaning block 61 upward, thus cleaning the aeration port 311. When the motor 5 rotates at a low speed, the drive block 622 is reset by a smaller centrifugal force, and the movable plate 621, no longer resisted by the drive block 622, resets under its own gravity and the action of the tension spring 624, thus moving the cleaning block 61 away from the aeration port 311. By changing the rotation speed to adjust the change in centrifugal force, the cleaning block 61 can periodically insert into the aeration port 311 to clean it. Simultaneously, the change in centrifugal force allows the oxygen discharged from the chamber column to be thrown further, enabling the oxygen to contact the water layer by layer, thereby improving the uniform mixing of oxygen and water.
