Description

Technical Field

[0001] This invention belongs to the field of photocatalytic treatment, specifically a photocatalytic water treatment device. Background Technology

[0002] While photocatalytic water treatment technology offers environmental advantages, its practical application has long been limited, primarily due to the following reasons: The conflict between light transmittance and fouling: the water layer thickness needs strict control (too thick a layer blocks light), but a thin water layer easily accelerates scaling on the catalyst surface, a problem that traditional technologies cannot solve simultaneously. Catalyst activity decay: biofilms or inorganic precipitates cover the catalyst's active sites, and manual cleaning is costly and disrupts operations. Equipment efficiency bottlenecks: the short water flow path in a single-stage reactor leads to incomplete pollutant degradation; ultraviolet lamps are only used for disinfection, failing to fully utilize their photocatalytic potential. Therefore, a photocatalytic water treatment device is proposed. Summary of the Invention

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0004] Given the following technical problems in the existing technology: fouling on the catalyst surface: during long-term operation, biofilms or precipitates are easily formed on the catalyst surface, blocking light penetration and significantly reducing photocatalytic efficiency;

[0005] Water layer thickness affects light transmittance: an excessively thick water layer will absorb or scatter ultraviolet light, weakening the excitation effect of light on the catalyst and leading to a decrease in degradation efficiency; low equipment space utilization: traditional devices do not make full use of the reaction chamber space, the water flow residence time is short, and the pollutants do not come into sufficient contact with the catalyst; high energy consumption and maintenance costs: the outer wall of traditional ultraviolet lamp tubes is prone to scaling and is difficult to clean, requiring frequent maintenance.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a photocatalytic water treatment device, comprising a treatment cylinder, wherein a treatment cavity is provided inside the treatment cylinder, and a light treatment mechanism, a stirring mechanism, a transmission mechanism and a catalytic mechanism are provided inside the treatment cavity;

[0007] An input pipe is provided at the top of the processing cavity, and an exhaust pipe is provided at the bottom of the processing cavity. The light processing mechanism includes a transparent cylinder, a central column, and light emission components. A vacuum cylindrical cavity is provided inside the transparent cylinder, a central column is provided in the middle of the vacuum cylindrical cavity, and several light emission components are evenly arranged around the central column.

[0008] As a preferred technical solution for photocatalytic water treatment equipment, the light-emitting component includes a reflective arc plate and an ultraviolet lamp tube. Several reflective arc plates are evenly arranged around the periphery of the central column, an ultraviolet lamp tube is arranged in the middle of the reflective arc plate, and a reflective coating is provided on the inner sidewall of the reflective arc plate.

[0009] The reflective coating reflects ultraviolet light, and the reflective arc plate gathers the ultraviolet light and then disperses it around the transparent tube, irradiating the surrounding water.

[0010] As a preferred technical solution for photocatalytic water treatment equipment, the transmission mechanism is connected to the top of the central column, and the transmission mechanism is also connected to the stirring mechanism, which is equipped with a catalytic mechanism.

[0011] As a preferred technical solution for photocatalytic water treatment equipment, the stirring mechanism includes a rotary table, a transmission frame, a vertical column, a horizontal plate, and a stirring plate. The rotary table is connected to the transmission mechanism. Three transmission frames are evenly arranged on the rotary table. A vertical column is fixedly connected to the end of each transmission frame away from the rotary table. A horizontal plate is provided at the top and bottom of the vertical column. Several stirring plates are arranged between two horizontal plates.

[0012] The rotating table slowly reverses through the vertical column, horizontal plate, and stirring plate, and the stirring mechanism stirs the water in the treatment chamber.

[0013] As a preferred technical solution for photocatalytic water treatment equipment, a connecting arc plate is provided between two adjacent vertical columns, and the number of the connecting arc plates is three.

[0014] As a preferred technical solution for photocatalytic water treatment equipment, a servo motor is installed at the bottom of the treatment cylinder, and the bottom of the central column is fixedly connected to the power output end of the servo motor.

[0015] As a preferred technical solution for a photocatalytic water treatment device, the transmission mechanism includes a treatment platform, a support rod, an internal gear ring, gear one, a movable cavity, gear two, and gear three. A movable cavity is provided on the inner side of the bottom of the treatment platform. An internal gear ring is rotatably connected in the movable cavity. Transmission teeth are provided on the inner circumferential wall of the internal gear ring. Gear one meshes with the inner wall of the internal gear ring. Gear one is connected to the central column through a transmission shaft. The treatment platform is located at the top of the treatment cavity. One side of the treatment platform is fixedly connected to the inner bottom wall of the treatment cavity through the support rod. Gear two and gear three are rotatably connected inside the treatment platform. Gear two and gear three mesh. Gear two is connected to the internal gear ring and is coaxial. The upper side of gear three is fixedly connected to the rotating platform through a transmission shaft.

[0016] The central column drives gear one to rotate. Gear one is decelerated through the internal gear ring, which reduces its speed. The internal gear ring drives gear two to rotate. Gear two drives gear three to rotate slowly in the opposite direction. Gear three drives the rotary table to rotate slowly in the opposite direction. The rotary table slowly reverses through the vertical column, horizontal plate and stirring plate, and the stirring mechanism stirs the water in the treatment chamber.

[0017] As a preferred technical solution for a photocatalytic water treatment device, the bottom end of the rotating table is rotatably connected to a rolling wheel, and the rolling wheel is movably connected to the upper side of the treatment table;

[0018] Rolling wheels support the rotary table.

[0019] As a preferred technical solution for a photocatalytic water treatment device, the vertical column is provided with several auxiliary seats, the auxiliary seats are in the shape of triangular prisms, and the auxiliary seats are located on the side of the stirring plate facing the center of the treatment chamber;

[0020] The attachment seat has several attachment grooves recessed therein, and the inner wall of the attachment grooves is provided with catalyst particles.

[0021] The auxiliary seat is located on the side of the stirring plate facing the center of the processing chamber, so that the ultraviolet lamp can irradiate the catalyst particles and generate active free radicals through catalysis for sterilization.

[0022] The beneficial effects of the photocatalytic water treatment device of the present invention are as follows: An inlet pipe is provided at the top of the treatment chamber, and an outlet pipe is provided at the bottom of the treatment chamber. The phototreatment mechanism includes a transparent cylinder, a central column, and light-emitting components. A vacuum cylindrical cavity is provided inside the transparent cylinder, and a central column is provided in the middle of the vacuum cylindrical cavity. Several light-emitting components are evenly arranged around the central column. Highly efficient dirt removal and anti-clogging: Through the counter-rotation of the stirring mechanism and the light-emitting components, combined with the physical wiping of the cleaning brush, the continuous rotation of the stirring mechanism generates friction with the water flow, achieving the purpose of automatically removing deposits on the catalyst surface and maintaining light transmittance.

[0023] The catalyst particles on the auxiliary seat are flushed by the rotation of the stirring plate and the water flow, reducing the adhesion of dirt.

[0024] To optimize light utilization and mixing efficiency, the elliptical inner wall design of the reflector plate concentrates ultraviolet light and disperses it evenly around the treatment cavity, expanding the irradiation range.

[0025] The stirring mechanism rotates in the opposite direction to the light source, which enhances the turbulence of the water flow, allowing the pollutants to come into full contact with the catalyst and improving the uniformity of degradation.

[0026] Compact structure and efficient use of space

[0027] Stacked designs (such as trays and rotating screens) increase the effective reaction area and reduce the equipment footprint; weir plates control the liquid layer thickness and balance light transmittance and reaction time.

[0028] The photovoltaic drive mechanism is directly integrated into the equipment, reducing cable wiring and achieving energy self-sufficiency.

[0029] Increasing the concentration of active free radicals (such as hydroxyl radicals) enhances oxidation capacity and shortens the treatment cycle. Attached Figure Description

[0048] The rotating table 18 slowly reverses through the vertical column 4, the horizontal plate 5 and the stirring plate 7, and stirs the water in the processing chamber 2 through the stirring mechanism.

[0050] A servo motor 12 is provided at the bottom of the processing cylinder 1, and the bottom of the central column 11 is fixedly connected to the power output end of the servo motor 12.

[0051] The transmission mechanism includes a processing table 16, a support rod 20, an internal gear ring 13, a first gear 14, a movable cavity 15, a second gear 17, and a third gear 19. The movable cavity 15 is provided on the inner side of the bottom of the processing table 16. The internal gear ring 13 is rotatably connected in the movable cavity 15. The inner peripheral wall of the internal gear ring 13 is provided with transmission teeth. The first gear 14 meshes with the inner wall of the internal gear ring 13. The first gear 14 is connected to the central column 11 through a transmission shaft. The processing table 16 is located on the top of the processing cavity 2.

The rotating table 18 slowly reverses through the vertical column 4, the horizontal plate 5 and the stirring plate 7, and stirs the water in the processing chamber 2 through the stirring mechanism.

[0053] The bottom end of the rotary table 18 is rotatably connected to a rolling wheel, and the rolling wheel is movably connected to the upper side of the processing table 16.

[0054] Roller supports the rotary table 18.

[0055] Several attachment seats 8 are provided on the vertical column 4. The attachment seats 8 are triangular prisms in shape and are located on the side of the stirring plate 7 facing the center of the processing chamber 2.

[0057] The auxiliary seat 8 is located on the side of the stirring plate 7 facing the center of the processing chamber 2, so that the ultraviolet lamp tube 26 can irradiate the catalyst particles and generate active free radicals through catalysis for sterilization.

[0058] The catalytic mechanism includes an auxiliary seat 8.

[0059] Several push plates 27 are evenly arranged on the outer side of the annular cleaning frame 9. The cleaning brush 24 contacts the outer peripheral surface of the transparent cylinder 10. Several rotating rods 28 are arranged on the inner side of the annular cleaning frame 9. Two track grooves 29 are arranged on the outer side of the transparent cylinder 10. The rotating rods 28 extend into the track grooves 29. During the rotation of the stirring plate 7, a forward or reverse vortex water flow is generated. The vortex water flow itself can not only clean the outer side of the transparent cylinder 10, but also push the annular cleaning frame 9 to rotate through the push plates 27. The annular cleaning frame 9 rotates with the rotating rods 28 and the cleaning brush 24. During the rotation of the cleaning brush 24, the outer peripheral surface of the transparent cylinder 10 is brushed.

[0060] The inner wall of the reflector plate 25 is elliptical, and the focal point of the ultraviolet lamp tube 26 is elliptical.

[0061] The ultraviolet lamp tube 26 generates ultraviolet light, and the reflector plate 25 focuses the light and disperses it from the center of the treatment chamber 2 to the surrounding area. After the ultraviolet light shines on the catalytic particles on the attachment seat 8, it catalytically disinfects the water.

[0062] The inner diameter of the internal gear ring 13 is four times the diameter of gear 14, while gears 2 and 3 have the same diameter.

[0063] The catalyst particles include nano-titanium dioxide.

[0064] The specific implementation method is as follows: water is injected into the processing chamber 2 through the input pipe 21, the servo motor 12 controls the rotation of the central column 11, the central column 11 drives the first gear 14 to rotate, the first gear 14 is decelerated through the internal gear ring 13, that is, the speed decreases, the internal gear ring 13 drives the second gear 17 to rotate, the second gear 17 drives the third gear 19 to rotate slowly in the opposite direction, the rotating table 18 rotates slowly in the opposite direction, the rotating table 18 slowly reverses through the vertical column 4, the horizontal plate 5 and the stirring plate 7, and the water in the processing chamber 2 is stirred by the stirring mechanism;

[0065] The stirring mechanism rotates in the opposite direction to the light-emitting component. The relative position of the light-emitting component and the attachment seat 8 changes continuously, so that all parts of the water are evenly irradiated and catalyzed to produce a two-stage reaction design that increases the concentration of active free radicals, enhances the ability to oxidize pollutants, and shortens the treatment cycle. The active free radicals include hydroxyl free radicals.

[0066] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0067] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
