Description

Technical Field

[0001] The present invention relates to the technical field of water purification, and specifically to an all-weather intermittent photocatalytic in-situ purification device. Background Art

[0002] With the acceleration of the urbanization process, the treatment of black and odorous water bodies has become a core challenge in water environment management. Due to problems such as direct sewage discharge, sediment deposition, and eutrophication in urban rivers and lakes, there is insufficient dissolved oxygen and enrichment of odorous substances (such as hydrogen sulfide and ammonia nitrogen), forming an apparent "black and odorous" pollution, which seriously threatens ecological safety and the health of residents.

[0003] Currently, common black and odorous water body treatment technologies include physical, chemical, biological and other methods. However, physical treatment technologies such as mechanical dredging and air flotation methods have high costs and affect the ecological environment. Chemical treatment technologies such as chemical precipitation and redox methods may introduce new pollutants and have a risk of secondary pollution. Although biological treatment technologies are effective, their repair cycle is long and they are greatly affected by environmental factors.

[0004] During the decomposition process of existing photocatalytic devices in urban black and odorous water bodies, in the actual application process, pollutants often adsorb on the surface of the photocatalyst or a biofilm grows, resulting in a decrease in its catalytic activity, making it difficult to achieve the ideal conditions for photocatalytic decomposition of black and odorous water, reducing the decomposition efficiency of black and odorous water, and having poor use effects. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In the present invention, by installing a cleaning component on the main body component, a photocatalytic component is detachably installed on the cleaning component. The main body component floats on the water body, and the photocatalytic component is immersed in the water body. It cooperates with the light source to perform photocatalytic decomposition of black and odorous water.

[0019] 2. In the present invention, the cleaning fluid in the liquid storage tank is introduced into the telescopic airbag through the liquid supply pipe by the water pump. The cleaning fluid synchronously flows into a plurality of telescopic airbags, and the telescopic airbags move vertically upward in the placement groove, lifting the photocatalytic component vertically upward above the water body. At the same time, the upper end inside the telescopic airbag is pressure-maintained through the elastic pressing component to prevent the cleaning fluid from being exported through the upper end, reducing the lifting pressure and ensuring the smooth upward movement of the photocatalytic component. After the internal pressure of the telescopic airbag is greater than the pressure-maintaining limit of the elastic pressing component, the elastic pressing component releases the pressure-maintaining state, allowing the cleaning fluid to be introduced into the cleaning body under high pressure. The cleaning body uses the high-pressure cleaning fluid to perform multi-point high-pressure flushing on the photocatalytic component lifted above the water body, decomposing and flushing the attachments and biofilms with the cleaning fluid to ensure the overall cleaning of the photocatalytic component.

[0020] 3. The present invention provides elastic force through a spring, enabling the sealing plug to abut and seal against the bottom inner wall of the top block. Consequently, the cleaning fluid can maintain a certain pressure within the telescopic airbag. After reaching the pressure limit, the cleaning fluid will push open the sealing plug, allowing the cleaning fluid to flow into the top block and the cleaning body, thereby discharging the high-pressure cleaning fluid. By replacing springs with different elastic force coefficients, the pressure limit value inside the telescopic airbag can be adjusted, and thus the pressure of the discharged cleaning fluid can be adjusted. The pressure adjustment is convenient and the applicable range is wide. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Preferably, as Figures 1-3 shown, the main body component 1 includes a hull 101, a through installation cavity 102 is opened in the middle of the hull 101, a plurality of placement grooves 103 with one side open are opened in the hull 101, the openings on one side of the placement grooves 103 communicate with the installation cavity 102, a thruster 104 is connected to the bottom end of the hull 101, and a liquid storage tank 106 is embedded and installed at one end of the hull 101. The liquid storage tank 106 is used to store cleaning fluid, the hull 101 is used to float on the water body, and the thruster 104 is used to drive the hull 101.

[0034] Specifically, the hull 101 floats on the water body and provides power to enable the overall operation of the device smoothly. An installation cavity 102 is opened inside the hull 101. Through the installation cavity 102, it is convenient for the photocatalytic component 3 to contact the water body and be irradiated by sunlight during the day to photocatalyze the black and odorous water body. The hull 101 can be fixed through the anchoring device, and a thruster 104 is connected to the bottom end of the hull 101, and it can also be propelled through the thruster 104 to perform mobile photocatalytic decomposition of black and odorous water, with a wide range of applications. A liquid storage tank 106 is embedded and installed at one end of the hull 101. The liquid storage tank 106 is used to store the cleaning fluid, and the cleaning fluid is used for cleaning the photocatalytic component 3;

[0035] Furthermore, the cleaning fluid includes hydrogen peroxide solution or pure water, etc.

[0036] Preferably, as Figures 3-6 shown, the cleaning component 2 includes a plurality of telescopic airbags 201. The plurality of telescopic airbags 201 are all installed in the corresponding placement grooves 103. The plurality of telescopic airbags 201 are connected by a pipe body. A hollow top block 202 is fixedly connected to the upper end of the telescopic airbag 201. The upper end of the telescopic airbag 201 communicates with the top block 202. A spring pressing component is installed in the top block 202. A side column 205 is welded to one side of the top block 202. The side column 205 is clamped in the opening. The bottom end of the side column 205 is bolted to the photocatalytic component 3. The bottom end of the telescopic airbag 201 is connected to a liquid supply pipe 208. The liquid supply pipe 208 is connected to the liquid outlet end of a water pump 207 and a solenoid valve 209. The liquid inlet end of the water pump 207 is connected to the liquid storage tank 106 through a pipe body. A cleaning body 206 is fixedly connected to the side column 205. The top block 202 is connected to the cleaning body 206 through a pipe body. The cleaning body 206 is used to spray the cleaning fluid. The spring pressing component is used for internal pressure maintenance when the telescopic airbag 201 rises vertically, so that the telescopic airbag 201 drives the photocatalytic component 3 to move vertically.

[0037] Specifically, a plurality of telescopic air bags 201 are installed in the corresponding placement grooves 103. When the telescopic air bags 201 are not pumped with cleaning fluid by the water pump 207, the telescopic air bags 201 are in a compressed and folded state. At this time, the photocatalytic component 3 connected to the side column 205 is immersed in water to perform photocatalysis on the black and odorous water. After reaching the set time, the control component 4 controls the water pump 207 to be powered on, so that the water pump 207 introduces the cleaning fluid in the liquid storage tank 106 into the telescopic air bags 201 through the liquid supply pipe 208. When the cleaning fluid synchronously flows into the plurality of telescopic air bags 201 and makes the telescopic air bags 201 move vertically upward in the placement grooves 103, the photocatalytic component 3 is vertically lifted above the water body. At the same time, the upper end inside the telescopic air bag 201 is internally pressurized through the elastic pressing component to prevent the cleaning fluid from being exported through the upper end, reduce the lifting pressure, and ensure the smooth upward movement of the photocatalytic component 3. After the internal pressure of the telescopic air bag 201 is greater than the pressure maintaining limit of the elastic pressing component, the elastic pressing component releases the pressure maintaining state, and the cleaning fluid is introduced into the cleaning body 206 under high pressure, so that the cleaning body 206 performs multi-point high-pressure flushing on the photocatalytic component 3 lifted to the upper end of the water body with the high-pressure cleaning fluid, and the cleaning fluid decomposes and flushes the attachments and biofilms to ensure the overall cleanliness of the photocatalytic component 3. After the flushing for the set time is completed, the water pump 207 stops running. After the cleaning of the photocatalytic component 3 is completed, the control component 4 controls the solenoid valve 209 to open, so that the cleaning fluid in the telescopic air bag 201 is exported through the outlet of the solenoid valve 209 in cooperation with the gravity of the photocatalytic component 3. After the fluid inside the telescopic air bag 201 is exported, the photocatalytic component 3 continues to be immersed in the water body to perform subsequent photocatalytic decomposition of the black and odorous water, ensuring the decomposition efficiency of the photocatalytic component 3.

Preferably, the working time of the photocatalytic component 3 is 4 hours, and the cleaning time is 2 hours. The "4 + 2" intermittent photocatalytic working mode is adopted, which can ensure the decomposition duration of the black and odorous water by the photocatalytic component 3 and also enable the photocatalytic component 3 to be cleaned, ensuring the overall decomposition efficiency.

[0039] Preferably, as Figures 3-6 shown, the elastic pressing component includes a spring 203 and a sealing plug 204. The spring 203 is connected to the upper end of the inner wall of the hollow top block 202, and the other end of the spring 203 is welded to the sealing plug 204, and the sealing plug 204 abuts against the bottom end of the inner wall of the top block 202.

[0040] Specifically, the elastic force is provided by the spring 203, so that the sealing plug 204 abuts against and seals the bottom of the inner wall of the top block 202, thereby enabling the cleaning fluid to maintain a certain pressure in the telescopic airbag 201. After reaching the pressure limit, the cleaning fluid will push open the sealing plug 204, allowing the cleaning fluid to flow into the top block 202 and the cleaning body 206, and then discharging the high-pressure cleaning fluid.

[0041] Furthermore, by replacing the spring 203 with different elastic coefficient, the pressure limit value inside the telescopic airbag 201 can be adjusted, and then the pressure of the discharged cleaning fluid can be adjusted. The pressure adjustment is convenient and the applicable range is wide.

[0045] Specifically, after the photocatalytic component 3 completes the high-pressure cleaning and rinsing, the mesh body 302 of the photocatalytic component 3 is immersed in the water body. The control component 4 controls the ultrasonic cleaner 210 to start, so that the ultrasonic waves generated by the ultrasonic cleaner 210 are transmitted through the water body, and the high-frequency vibration is transmitted to the mesh body 302 of the photocatalytic component 3 through the water body to perform secondary cleaning on the mesh body 302, and the cleaning effect is good.

The overall radially arranged mesh body 302 is adapted to multiple cleaning bodies 206 to eject inclined and fan-shaped high-pressure cleaning fluid, enabling the debris on the mesh body 302 to be quickly cleaned, ensuring that the photocatalyst 303 on the mesh body 302 is in full contact with the water body, and ensuring the photocatalytic decomposition efficiency of black and odorous water.

[0048] Furthermore, the frame 301 is detachably installed on the side column 205. The frame 301 and the mesh body 302 are integrally installed and replaced conveniently.

The light sensor 402 is used for light intensity induction and controls the turning on or off of the lamp bodies 403 through the control console 401.

[0050] Specifically, the control console 401 controls the turning on or off of the lamp bodies 403. The light sensor 402 detects the light intensity and forms a corresponding electrical signal, which is transmitted to the control console 401. In the case of insufficient light conditions, the control console 401 controls the lamp bodies 403 to turn on for light source supplementation, enabling the device to perform all-weather photocatalytic decomposition, further improving the water purification efficiency, and having a good use effect.

[0051] Furthermore, the control console 401 has a central processor and an input / output terminal. The control console 401 controls the water pump 207, the solenoid valve 209, and the ultrasonic cleaner 210 to work at regular intervals and intermittently, thereby vertically lifting the frame 301 and the mesh body 302 as a whole and self-cleaning the mesh body 302.

[0052] Preferably, as Figure 2 shown, a plurality of flow guide plates 105 are welded to the bottom of the hull 101. The plurality of flow guide plates 105 and the plurality of lamp bodies 403 are distributed around the mesh body 302.

[0053] Specifically, a plurality of flow deflectors 105 are welded to the bottom of the hull 101. The flow deflectors 105 conduct water flow diversion, and at the same time, multiple flow deflectors 105 and multiple lamp bodies 403 surround and protect the net body 302 to prevent large debris from damaging the net body 302.

[0054] Preferably, as Figure 3 shown, it further includes an energy component 5. The energy component 5 includes a solar panel 501 and a storage battery 502. The solar panel 501 is inclined and fixedly connected to the upper end of the hull 101, and the storage battery 502 is embedded and connected in the hull 101.

[0055] Specifically, the solar panel 501 can efficiently absorb sunlight and convert it into electric energy. The electric energy is connected to the hull 101. Part of it is supplied for the daily operation of the whole device, and the excess part is stored in the storage battery 502 to ensure that standby power is provided in the absence of sunlight or insufficient light, enabling the device to still work continuously and stably. It is not only environmentally friendly and energy-saving, but also greatly improves the independent operation ability and application range of the device, enabling it to achieve excellent water purification effects in various environments.

[0056] A method for coating a photocatalyst includes:

[0057] Prepare an aqueous solution of polyethyleneimine with a mass fraction of 1% - 5% for standby;

[0058] Use deionized water and absolute ethanol to alternately clean the nylon rope to remove surface dust and impurities;

[0059] Completely immerse the nylon rope in the aqueous solution of polyethyleneimine and keep it for 5 - 30 minutes to ensure uniform coating on its surface, and then place it in a well-ventilated environment to dry naturally for 1 - 2 hours to let the surface solvent volatilize completely;

[0060] Set the curing temperature at 60 - 100 °C, and use an oven or a hot plate to carry out heat treatment for 1 - 2 hours to make the polyethyleneimine adhere more firmly to the nylon rope, ensuring that its chemical functional groups can provide better catalyst adhesion. After curing, take the nylon rope out of the heat source and let it cool naturally at room temperature;

[0061] After the coating treatment is completed, the catalyst powder can be attached to the nylon rope with a surface treated with polyethyleneimine by soaking or spraying, and appropriate adsorption time and conditions are set according to the characteristics of the catalyst;

[0062] Through the above process, a modified coating can be effectively formed on the nylon rope to enhance the binding performance with the catalyst, thereby improving its catalytic efficiency.

[0063] Specifically, the mesh body 302 serves as a carrier, and its surface is coated with a photocatalyst 303, which can decompose harmful substances in water under light conditions, improving the water purification effect. During the operation process, appropriate protective equipment such as gloves and masks should be worn to avoid inhaling the dust of polyethyleneimine. At the same time, ensure that the working environment is well-ventilated so that the volatile solvents can be quickly discharged. The soaking time of the mesh body 302 needs to be reasonably controlled to ensure that the photocatalyst 303 fully penetrates and adheres to the fibers of the mesh body 302. The mesh body 302 treated with a chemical coating can not only enhance the water purification ability of the water body, but also extend its service life, improving the stability and durability of the overall equipment.

[0064] As described above, it is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
