Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to a photocatalytic water treatment device. Background Art

[0002] Photocatalytic water treatment uses photocatalysts (such as titanium dioxide, etc.) to be irradiated with ultraviolet light, so that the photocatalyst absorbs light energy and converts it into electrons and holes. The electrons and holes combine on the surface of the photocatalyst to form free radicals. The free radicals can oxidize pollutants in the water and convert them into harmless substances. The catalyst needs to be in the water during the photocatalytic process, and it is inconvenient to recycle the general catalyst directly into the water. For example, titanium dioxide nanoparticles are very small and easily condensed in aqueous solution, making it difficult to separate and recycle. In addition, the catalyst easily aggregates to form suspended matter when floating in the water. The suspended catalyst particles may block the light, resulting in only the catalyst particles on the surface receiving enough light energy to react, while the particles inside cannot fully utilize the light energy, resulting in the photocatalyst being made into a coating or film for photocatalytic treatment in actual use;

[0003] Before the sewage is subjected to photocatalytic treatment, it is usually pretreated. First, the sewage is precipitated in a sedimentation tank to reduce the content of solid matter such as particulate matter in the sewage. Then, a flocculant is added to the sewage and then filtered to make the sewage clear and transparent after pretreatment, which is convenient for ultraviolet irradiation. In addition, during the photocatalytic treatment, hydrogen peroxide is mixed in the pretreated sewage to improve the oxidation capacity of the sewage and promote the sewage reaction. However, after pretreatment, some sewage may not be transparent due to excessive soluble organic matter in the sewage or the presence of natural or synthetic pigments. Colored sewage is easy to affect ultraviolet irradiation of photocatalysts, which is inconvenient. In addition, general photocatalytic water treatment equipment uses water flow to pass through the photocatalyst for treatment. Long-term flushing of water flow is easy to affect the photocatalyst coating, reducing the service life of the photocatalytic coating, which is inconvenient. In addition, during the photocatalytic reaction, organic pollutants and microorganisms in the water will be degraded on the surface of the photocatalyst, but at the same time, some substances will be deposited on the surface of the membrane or coating. If these sediments are not removed in time, they will affect the light transmittance and the active sites of the catalyst, thereby reducing the photocatalytic efficiency. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. By mixing sewage with hydrogen peroxide and injecting it into multiple treatment mechanisms, the treatment mechanisms can reduce the thickness of sewage, making it easier for ultraviolet rays to penetrate the sewage and irradiate the catalyst layer, thereby facilitating the photocatalytic treatment of opaque sewage. By containing sewage, the service life of the catalyst layer can be reduced by long-term scouring of sewage. At the same time, the treatment mechanisms are started to allow the sewage inside the treatment mechanisms to fully contact the catalyst layer, thereby improving the efficiency of photocatalysis. The treatment mechanisms can also intermittently wipe the catalyst layer to remove the sediment thereon, thereby improving the efficiency of photocatalytic water treatment.

[0020] 2. Mix sewage and hydrogen peroxide and add them to the space between the partition and the glass plate. Then, use a suction mechanism to fill the isolation covers on all treatment mechanisms with sewage to reduce the impact of sewage scouring on the catalyst layer. Start the ultraviolet lamp in the light box to allow ultraviolet rays to irradiate the catalyst layer through the glass plate and the isolation cover. The isolation cover is thin, and the space between the partition and the glass plate is thin, thereby reducing the thickness of the sewage and facilitating the penetration of ultraviolet rays. The ultraviolet rays can irradiate the sewage between the partition and the glass plate to sterilize and disinfect the sewage. Then, start the vibration motor in the vibration box to drive the sewage in the adjacent isolation cover to vibrate, so that the sewage is fully in contact with the catalyst layer, thereby improving the photocatalytic efficiency.

[0021] 3. Start the drive motor to drive the shaft to rotate, so that the shaft drives multiple gears to revolve around the gear ring and rotate through the support arm, so that the gear drives the adjacent vibration boxes and isolation covers to revolve around the gear ring and rotate synchronously, so that multiple isolation covers stir the sewage in the space between the partition and the glass plate, and improve the efficiency of ultraviolet sterilization of sewage. When it is necessary to fill all isolation covers with sewage, the drive motor can be started to make the number of isolation covers on the opposite sides of the X-axis equal and the sockets on them face the same direction, and then start the two cylinders to drive the adjacent sleeve frames to move, so that the sleeve frames drive the two adjacent pulling plates to rotate, so that the pulling plates drive the adjacent sliding pipes to insert into the adjacent sockets, so that the multiple isolation covers on the same side of the X-axis can be The sockets are all inserted by the sliding pipes of the adjacent suction mechanisms, and then the air pump is started to suck through the sliding pipe and the hose to drive the piston plate in the isolation cover to move, so that when the piston plate moves, the sewage in the space between the partition and the glass plate is filled into the isolation cover, and the piston plate is close to the sliding pipe on the adjacent suction mechanism at this time. When it is necessary to extract the sewage in the isolation cover, the driving motor can be started to rotate the isolation covers located on the opposite sides of the X-axis to the position where they are located on the X-axis when they are initially sucked in, so that the piston plate in the isolation cover is away from the sliding pipe on the adjacent suction mechanism, and then the two suction mechanisms are started again to extract the sewage in the isolation cover after photocatalytic treatment out of the isolation cover, and the sewage between the partition and the glass plate is synchronously sucked into the isolation cover;

[0022] 4. By injecting hydrogen peroxide and pre-treated sewage into a fixed pipe, and then starting the driving motor to drive the rotating shaft to rotate, the rotating shaft drives the circular plate to rotate, and makes multiple stirring shafts revolve around the center of the circular plate. At the same time, the stirring shaft is driven by the adjacent gears to rotate, so that the multiple stirring shafts and the rotating shaft drive the adjacent stirring rods to rotate, and the multiple stirring shafts revolve around the rotating shaft, thereby mixing the sewage and hydrogen peroxide in the fixed pipe, improving the mixing efficiency, and the mixed sewage can be pumped into the space between the glass plate and the partition through a water pump.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 6 In an embodiment of the present invention, a photocatalytic water treatment device includes:

[0032] A box body 100, a connecting frame 200 for carrying an ultraviolet lamp, a plurality of treatment mechanisms 300 for photocatalytic treatment of sewage and two suction mechanisms 400, the box body 100 is fixedly connected with brackets 110 on opposite sides, the box body 100 is a bottom-opening structure, and a glass plate 101 is fixedly sleeved on the inner side of the bottom of the box body 100, the connecting frame 200 is fixedly connected to the bottom of the box body 100, and the connecting frame 200 is equipped with a plurality of light boxes 210, and the plurality of treatment mechanisms 300 are all located inside the box body 100, and the treatment mechanisms 300 include a vibration box 310, and the vibration boxes 310 are all hollow structures, and a vibration motor is arranged inside the vibration box 310, and one side of the vibration box 310 is fixedly connected A catalyst layer 311 is provided, an isolation cover 320 is arranged on one side of the vibration box 310, and the isolation cover 320 is an open structure on one side, one side of the isolation cover 320 is fixedly connected to one side of the vibration box 310, a plurality of sockets 321 are provided on opposite sides of the isolation cover 320, and slide grooves are provided on two opposite inner walls of the isolation cover 320, a piston plate 330 is slidably sleeved inside the isolation cover 320, and both ends of the piston plate 330 are slidably engaged in the two slide grooves, the other side of the isolation cover 320 on any processing mechanism 300 is abutted against one side of the glass plate 101, and the two suction mechanisms 400 are both located outside the box body 100, and the two suction mechanisms 400 are diagonally arranged with the center of the box body 100 as the center.

[0033] Specifically, an ultraviolet lamp is arranged inside the light box 210, the glass plate 101 and the isolation cover 320 are both made of glass that can transmit ultraviolet rays, a battery box is arranged inside the vibration box 310 for powering the vibration motor, and the thickness of the isolation cover 320 is relatively thin, and the catalyst layer 311 on the vibration box 310 is a titanium dioxide coating. When in use, the sewage that has been precipitated and flocculated by adding a flocculant and filtered is added to the glass plate 101 and received by the glass plate 101, and hydrogen peroxide can also be added to the sewage to mix and improve the oxidation efficiency of the sewage, and then the piston plate 330 in the isolation cover 320 is moved to make When the piston plate 330 moves, the sewage is sucked through the socket 321 on one of the two opposite sides of the adjacent isolation cover 320, so that the sewage enters the isolation cover 320, and the piston plate 330 blocks the socket 321 on the other of the two opposite sides of the adjacent isolation cover 320, so that the sewage in the isolation cover 320 does not flow, and the sewage is prevented from leaving the isolation cover 320. Then, the ultraviolet lamp in the light box 210 is started, and the ultraviolet rays are transmitted through the glass plate 101 and the isolation cover 320 to irradiate the catalyst layer 311, so that the catalyst layer 311 performs photocatalytic treatment on the sewage in the isolation cover 320. The vibration motor in the vibration box 310 makes the sewage inside the isolation cover 320 vibrate synchronously with the vibration box 310, so that the sewage is fully in contact with the catalyst layer 311, thereby improving the efficiency of photocatalysis. In addition, during the photocatalytic process and the process of sewage entering and exiting the isolation cover 320, due to the low sewage flow rate, the impact on the titanium dioxide coating is small, thereby improving the life of the titanium dioxide coating. In addition, the piston plate 330 is made of rubber. When the piston plate 330 moves, it can intermittently wipe the catalyst layer 311 and the isolation cover 320 and push the sewage in the isolation cover 320, thereby removing the sewage in the isolation cover 320 and on the catalyst layer 311. The dirt or sediment is scraped off by the piston plate 330 and discharged together with the sewage when the sewage inside the isolation cover 320 is discharged, which is convenient for cleaning the sediment on the catalyst layer 311. In addition, since the isolation cover 320 is thin, the thickness of the sewage inside the isolation cover 320 is also thin, which is convenient for ultraviolet rays to penetrate. Even if the sewage is opaque due to the presence of pigments, soluble organic matter, etc., it is easy for the ultraviolet rays to penetrate due to the thin thickness of the sewage inside the isolation cover 320, which is convenient for the catalyst layer 311 to perform photocatalytic treatment on the sewage. The vibration motor, battery box, titanium dioxide coating, ultraviolet lamp, etc. are all existing technologies and will not be repeated here.
