Description

Technical Field

[0001] The invention relates to the technical field of water treatment, and in particular to a device and method for sterilizing and killing algae in an industrial circulating water system based on nano rare earth. Background Art

[0002] The mechanism of nano rare earth materials in sterilizing water and killing algae: using the narrow band gap characteristics of rare earth elements, strong oxidizing hydroxyl radicals and superoxide radicals are generated under ultraviolet light excitation to destroy the cell structure of microorganisms; In the process of sterilization and algae removal, the degree of use of nano rare earth materials determines the service life of the device, because different water flow rates require corresponding strong oxidizing hydroxyl radicals and superoxide radicals. When the flow rate is too small, the substance produced is greater than the required amount, which will cause unnecessary waste. In the prior art, regardless of the amount of water, the nano rare earth materials will be exposed to the water, so during use, the nano rare earth materials are always in contact with water. The impact of impurities in the water flow and the friction of the water flow will cause wear on the nano rare earth materials, thereby causing the loss of nano rare earth materials and affecting the service life of the device. In addition, because the circulating water and the internal dirt and impurities are relatively large, the penetration rate of ultraviolet light is affected, thereby affecting the efficiency of photocatalysis.

[0011] A method for sterilizing and killing algae in an industrial circulating water system based on nano rare earths, which is applicable to the above-mentioned device for sterilizing and killing algae in an industrial circulating water system based on nano rare earths, comprises the following steps: Step 1: Connect the pipe fittings to the circulating water pipe; Step 2: The water in the tube will slowly pass through filter 2 and filter 1 into the inside of the cover. Filter 2 and filter 1 filter impurities and reduce the impact of water flow; Step 3: The filtered water contacts the surface of the nano rare earth coating inside the cover, and the ultraviolet light generator corresponding to the nano rare earth coating is started. The ultraviolet light generator penetrates the transparent glass to irradiate the back of the nano rare earth coating, and the front of the nano rare earth coating contacts the water entering the cover.

The controller controls the push rod motor to push the connecting plate 2 and the connecting plate 1 to move, and pulls the piston scraper to move.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention installs a uniform consumption mechanism to make the ultraviolet light control mechanism, the consumption control mechanism and the photocatalytic control mechanism evenly contact with water flows of different flow rates, so that the consumption of the nano rare earth coating at different positions is more uniform. The position of the square tube is changed during rotation, so that the water mixed with strong oxidizing hydroxyl radicals and superoxide radicals is discharged more evenly, thereby ensuring the uniformity of sterilization and algae removal; 2. The present invention installs a consumption control mechanism to divert the water flow, thereby preventing the water flow from rushing against the filter port. The water flow and the impurities contained inside strongly impact and rub the nano rare earth coating, causing damage to the nano rare earth coating, resulting in the loss of the nano rare earth coating, and affecting the service life of the entire equipment; 3. The present invention improves the efficiency of photocatalysis by installing an ultraviolet light control mechanism, a photocatalytic control mechanism 1 and a photocatalytic control mechanism 2 in an unobstructed irradiation mode to avoid the problem that the water flow is located between the ultraviolet light and the nano rare earth coating and affects the penetration of the ultraviolet light. The amount of the nano rare earth coating used is adjusted according to the water flow rate, and the impact of water on the nano rare earth when it is not needed is reduced, causing the loss, so that the nano rare earth coating does not meet the conditions for photocatalysis, thereby ensuring the life of the nano rare earth coating. In addition, when necessary, the dirt on the surface of the nano rare earth coating is cleaned to ensure the sterilization and algaecide effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] A method for sterilizing and killing algae in an industrial circulating water system based on nano rare earths, which is applicable to the above-mentioned device for sterilizing and killing algae in an industrial circulating water system based on nano rare earths, comprises the following steps: Step 1: Connect the pipe 1 to the circulating water pipe; Step 2: The water in the tube body 11 slowly passes through the filter screen 2 510 and the filter screen 1 53 and enters the interior of the cover 51. The filter screen 2 510 and the filter screen 1 53 filter out impurities and reduce the impact of the water flow. Step 3: The filtered water contacts the surface of the nano rare earth coating inside the cover 51, and the ultraviolet light generator 44 corresponding to the nano rare earth coating is started. The ultraviolet light generator 44 penetrates the transparent glass 42 to irradiate the back of the nano rare earth coating, and the front of the nano rare earth coating contacts the water entering the cover 51. When the ultraviolet light irradiates the back, the position where the nano rare earth coating contacts the water generates strong oxidizing hydroxyl radicals and superoxide radicals that destroy the cell structure of microorganisms, so that the strong oxidizing hydroxyl radicals and superoxide radicals are mixed in the water; Step 4: The water flow outside the cover 51 contacts the second fan blade 56, so that the second fan blade 56 drives the impeller 55 to rotate in the square tube 54. The rotation speed of the impeller 55 is proportional to the water flow rate. The water containing strong oxidizing hydroxyl free radicals and superoxide free radicals in the cover 51 is extracted and mixed with other water in the tube body 11. The impeller 55 further mixes the water with the strong oxidizing hydroxyl free radicals and superoxide free radicals during the extraction process. The extracted water is mixed with the flowing water to kill the microorganisms. Step five: The controller 6 obtains the detection data of the water flow detector, and adjusts the usage of the nano rare earth coating according to the detection data. The controller 6 controls the push rod motor 71 to push the connecting plate 2 72 and the connecting plate 1 73 to move and pull the piston scraper 74 to move. The piston scraper 74 pushes the water in the cover 51 toward the water outlet 57, and pushes the water out of the cover 51, so that the nano rare earth coating does not contact the water, and the nano rare earth coating does not meet the conditions for photocatalysis.

[0033] Working principle: The pipe fitting 1 is connected to the circulating water pipe. The circulating water passes through the pipe body 11. After the water flow contacts the curved surface of the anti-impact cover 59, the anti-impact cover 59 diverts the water to one side to avoid impacting the filter port 52. The water flow impacting the filter port 52 will cause the water flow to impact and rub the nano rare earth coating, and the impurities contained in the water will also damage the nano rare earth coating during the impact, causing the loss of the nano rare earth coating and affecting the service life of the entire equipment. The water in the pipe body 11 will slowly pass through the filter screen 2 510 and the filter screen 1 53 into the interior of the cover 51. The filter screen 2 510 and the filter screen 1 53 reduce the impact force of the water flow while filtering the impurities. The water entering the cover 51 will contact the nano rare earth coating inside the cover 51. The ultraviolet light generator 44 corresponding to the nano rare earth coating is started, and the ultraviolet light generator 44 penetrates the transparent glass 42 to irradiate the back of the nano rare earth coating. There is only the transparent glass 42 between the ultraviolet light generator 44 and the nano rare earth coating. Therefore, this unobstructed irradiation method avoids the problem that the water flow is located between the ultraviolet light and the nano rare earth coating to block the penetration of the ultraviolet light, thereby affecting the efficiency of photocatalysis. The front side of the nano rare earth coating contacts the water entering the cover 51, and when the ultraviolet light is irradiated, strong oxidizing hydroxyl radicals and superoxide radicals that destroy the cell structure of microorganisms are generated, and the strong oxidizing hydroxyl radicals and superoxide radicals are mixed in the water; The water outside the cover 51 contacts with the second fan blade 56, so that the second fan blade 56 drives the impeller 55 to rotate in the square tube 54. The rotation of the impeller 55 generates a slight suction force, and the water containing strong oxidizing hydroxyl free radicals and superoxide free radicals in the cover 51 is extracted and mixed with other water in the tube body 11. The impeller 55 further mixes the water with the strong oxidizing hydroxyl free radicals and superoxide free radicals during the extraction process. The extracted water is mixed with the water flowing through, killing microorganisms and achieving sterilization and algae removal. The rotation of the impeller 55 will also generate negative pressure in the cover 51, so that the speed at which the water passes through the filter screen 1 53 and the filter screen 2 510 corresponds to the speed of the impeller 55 rotation. Therefore, when the water flow in the pipeline is large, the rotation speed of the impeller 55 becomes faster and the speed of extracting the internal water also becomes faster. Therefore, the addition speed is increased according to the amount of water, and the mixed water is discharged by pumping, which can reduce the impact of the large flow of external water flow and damage to the coating. The controller 6 obtains the detection data of the water flow detector, and adjusts the usage of the nano rare earth coating according to the detection data. The controller 6 controls the push rod motor 71 to push the connecting plate 2 72 and the connecting plate 1 73 to move and pull the piston scraper 74 to move. The piston scraper 74 pushes the water in the cover 51 toward the water outlet 57 and pushes the water out of the cover 51, so that the nano rare earth coating does not contact the water. The spring telescopic rod 76 will push the sealing plate 77 to move after there is no squeezing of the piston scraper 74, so as to block the filter port 52. When the piston scraper 74 moves, the block 75 is pulled out of the hot air pipe 58. When negative pressure is generated on one side of the piston scraper 74, gas will enter from the hot air pipe 58, and the hot air pipe 58 draws external gas through the annular groove 35, the air pipe 33 and the multi-way control valve 32 to replenish the inside, so as to avoid water seepage at the position blocked by the sealing plate 77 due to negative pressure; After the internal water is drained, there will still be moisture on the surface of the nano rare earth coating, so the hot air blower 31 is started to blow hot air through the air pipe 33 into the annular groove 35, and then the hot air enters the interior of the cover 51 through the hot air pipe 58 that is not blocked by the block 75 to dry the inside of the cover 51. The controller opens the electric valve 78, and the gas is ejected from the electric valve 78. After the drying is completed, the electric valve 78 is closed to dry the inside, and the water is drained and the corresponding ultraviolet light generator 44 is turned off. After the water is drained, the water can reduce the impact of water on the nano rare earth when it is not needed. Impact, avoid loss, avoid other unclosed ultraviolet light control mechanism light refraction to the nano rare earth coating when the nano rare earth coating and water continue to photocatalyze, so after the water is discharged, the nano rare earth coating does not meet the conditions of photocatalysis, to ensure the life of the nano rare earth coating, can also be moved by the piston scraper 74 to scrape away the precipitation on the surface of the nano rare earth coating, avoid affecting the photocatalysis, to ensure the efficiency of photocatalysis, so when the water flow rate rises and falls, choose the amount of nano rare earth coating, to ensure the sterilization and algaecide effect, while ensuring the service life of the nano rare earth coating, reduce the frequency of maintenance; Because the flow rates of the upper and lower layers of water in the pipeline are different, when the water flow contacts the fan blade 26, the rotating shaft 25 and the bevel gear 27 are driven to rotate. The rotation of the bevel gear 27 drives the bevel gear 23 to rotate. The bevel gear 23 drives the rotating shaft 22 and the cylinder 41 to rotate. The rotation of the cylinder 41 drives the annular groove 35 seal to rotate, while the ring plate 34 remains stationary. The rotation of the cylinder 41 drives the ultraviolet light control mechanism 4, the consumption control mechanism 5 and the photocatalytic control mechanism 27 and other structures to rotate, so that the ultraviolet light control mechanism 4, the consumption control mechanism 5 and the photocatalytic control mechanism 27 are in contact with water flows of different flow rates, so that the consumption of the nano rare earth coating is more uniform. The position of the square tube 54 is changed during rotation, so that the water mixed with strong oxidizing hydroxyl free radicals and superoxide free radicals is discharged more evenly, thereby ensuring the uniformity of sterilization and algae removal.

8. A method for sterilizing and killing algae in an industrial circulating water system based on nano rare earth, which is applicable to the device for sterilizing and killing algae in an industrial circulating water system based on nano rare earth as claimed in claim 7, characterized in that: The following steps are involved: Step 1: Connect the pipe fitting (1) to the circulating water pipe; Step 2: The water in the tube body (11) slowly passes through the second filter screen (510) and the first filter screen (53) and enters the interior of the cover (51). The second filter screen (510) and the first filter screen (53) filter impurities and reduce the impact force of the water flow. Step 3: The filtered water contacts the surface of the nano rare earth coating inside the cover (51), and the ultraviolet light generator (44) corresponding to the nano rare earth coating is activated. The ultraviolet light generator (44) penetrates the transparent glass (42) to irradiate the back of the nano rare earth coating. The front of the nano rare earth coating contacts the water entering the cover (51). When the ultraviolet light irradiates the back, the position where the nano rare earth coating contacts the water generates strong oxidizing hydroxyl radicals and superoxide radicals that destroy the cell structure of microorganisms, so that the strong oxidizing hydroxyl radicals and superoxide radicals are mixed in the water. Step 4: The water flow outside the cover (51) contacts the second fan blade (56), so that the second fan blade (56) drives the impeller (55) to rotate in the square tube (54). The rotation speed of the impeller (55) is proportional to the water flow rate. The water containing strong oxidizing hydroxyl free radicals and superoxide free radicals in the cover (51) is extracted and mixed with other water in the tube body (11). The impeller (55) further mixes the water with the strong oxidizing hydroxyl free radicals and superoxide free radicals during the extraction process. The extracted water is mixed with the water flowing through, thereby killing the microorganisms. Step 5: The controller (6) obtains the detection data of the water flow detector, and adjusts the usage of the nano rare earth coating according to the detection data. The controller (6) controls the push rod motor (71) to push the connecting plate 2 (72) and the connecting plate 1 (73) to move and pull the piston scraper (74) to move. The piston scraper (74) pushes the water in the cover (51) toward the water outlet (57) and pushes the water out of the cover (51), so that the nano rare earth coating does not contact the water, and the nano rare earth coating does not meet the conditions for photocatalysis.
