Description

Technical Field

[0001] This utility model relates to the field of drinking water treatment, and in particular to a combined ozone activated carbon type water purification device. Background Technology

[0002] The combined ozone-activated carbon water purification equipment is a deep water purification device that integrates ozone oxidation technology and activated carbon adsorption technology. Through the synergistic effect of the two technologies, it can efficiently remove pollutants from water and improve water safety and taste.

[0003] Existing combined ozone-activated carbon water purification equipment is an integrated deep water purification device consisting of an ozone oxidation system and an activated carbon filtration system as its core, supplemented by a pretreatment unit and automatic control components. The raw water is first pretreated to remove coarse impurities. After entering the ozone contact section, the strong oxidizing ozone quickly kills bacteria, viruses and other microorganisms in the water, while decomposing large organic molecules such as pesticides and humic acid into easily adsorbed small molecules. Then the water flows into the activated carbon filtration section, where the activated carbon adsorbs residual organic matter, heavy metals and unreacted ozone with its porous structure, and finally outputs clean water.

[0004] Traditional combined ozone-activated carbon water purification equipment relies solely on activated carbon for purification, which is insufficient to adsorb pollutants such as colloidal particles, bacterial remains, and large organic molecules. Furthermore, the selectivity of ozone oxidation and the limited adsorption capacity of activated carbon result in the combined ozone-activated carbon water purification equipment failing to completely remove fine pollutants not treated in previous stages, as well as residual intermediate products and purification blind spots caused by adsorption saturation. Therefore, a combined ozone-activated carbon water purification equipment is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a combined ozone activated carbon water purification device, which aims to improve the problem that the existing technology cannot deeply remove pollutants by simply using activated carbon.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A combined ozone-activated carbon water purification device includes an ozone reaction tank. An activated carbon filter is fixedly connected to the bottom of the ozone reaction tank. An outlet is provided on the side of the activated carbon filter away from the ozone reaction tank. A water pipe is fixedly connected to the top of the ozone reaction tank. A pipe body is fixedly connected to the end of the water pipe away from the ozone reaction tank. An ozone recovery component is provided on the top side of the ozone reaction tank away from the pipe body. A central pipe is fixedly connected inside the pipe body. A water flow hole is provided on the outer wall of the central pipe. A diaphragm is installed inside the pipe body. A cover is fixedly connected to the top of the pipe body. A second outlet is provided on the top of the cover. A second inlet is provided on the outer wall of the pipe body. A quartz sand filter is fixedly connected to the outer wall of the water pipe. A water pump is fixedly connected to the end of the quartz sand filter away from the pipe body. An inlet is fixedly connected to the input end of the water pump. As a further description of the above technical solution: The ozone recovery assembly includes an induced draft fan housing, which is fixedly connected to the top of the ozone reaction tank. A motor is fixedly connected inside the induced draft fan housing, and a rotating shaft is fixedly connected to the output end of the motor. A fixed column is rotatably connected inside the induced draft fan housing. Bevel gears are fixedly connected to the top of the rotating shaft and the outer wall of the fixed column. Fan blades are fixedly connected to the outer wall of the fixed column. An air filter is fixedly connected inside the induced draft fan housing. A cyclone separator is fixedly connected to the induced draft fan housing through a water pipe. A catalytic tower is fixedly connected to the cyclone separator through a water pipe. As a further description of the above technical solution: The diaphragm is fixedly connected to the side of the tube body near the central tube; As a further description of the above technical solution: The quartz sand filter is fixedly connected to the side of the water inlet away from the pipe body; As a further description of the above technical solution: The water pump is fixedly connected to the side of the quartz sand filter away from the pipe body; As a further description of the above technical solution: The second water inlet is located on the side of the pipe body away from the central pipe; As a further description of the above technical solution: The cyclone separator has an air inlet on the side near the outer casing of the induced draft fan, and an air outlet on the top of the cyclone separator. As a further description of the above technical solution: The bottom of the catalytic tower is provided with an air inlet 2, and the side of the catalytic tower away from the air inlet 2 is provided with an air outlet 2.

[0007] This utility model has the following beneficial effects: In this invention, raw water is introduced into the central pipe through the second inlet, guided into the pipe body, and then evenly distributed through the water flow holes. The pipe body and the cover form a water storage space to temporarily store the raw water. After deep filtration by the membrane, the purified water is discharged from the second outlet, which helps to improve the water purification efficiency and quality of the water purification equipment.

[0008] 2. In this invention, a motor drives a rotating shaft to rotate, which in turn drives a bevel gear to rotate. The bevel gear then drives a fixed column and the fan blades on the surface of the fixed column to rotate. This allows residual ozone to be drawn from the ozone reaction tank to the cyclone separator through a water pipe. The cyclone separator causes the ozone to rotate at high speed inside. The centrifugal force generated by the rotation of the ozone causes particles with a density greater than that of the fluid to be thrown against the wall of the separator. The purified ozone then enters the catalytic tower through the air outlet. Under the action of the catalyst placed in the catalytic tower, the residual ozone that did not directly participate in the reaction continues to decompose or transform under the action of the catalyst. This helps to reduce the ineffective emission of ozone and lower the risk of secondary pollution caused by low ozone utilization and ozone emission. Attached Figure Description

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Reference Figures 1-2 This utility model provides an embodiment of a combined ozone-activated carbon water purification device, comprising an ozone reaction tank 1, an activated carbon filter 15 fixedly connected to the bottom of the ozone reaction tank 1, an outlet 2 on the side of the activated carbon filter 15 away from the ozone reaction tank 1, a water pipe 3 fixedly connected to the top pipe of the ozone reaction tank 1, a pipe body 4 fixedly connected to the end of the water pipe 3 away from the ozone reaction tank 1, an ozone recovery component 5 disposed on the top side of the ozone reaction tank 1 away from the pipe body 4, a central pipe 6 fixedly connected inside the pipe body 4, a water flow hole 7 opened on the outer wall of the central pipe 6, a diaphragm 8 installed inside the pipe body 4, and the pipe body 4... A cover 9 is fixedly connected to the top, and a second water outlet 12 is opened on the top of the cover 9. A second water inlet 13 is opened on the outer wall of the pipe body 4. A quartz sand filter 10 is fixedly connected to the outer wall of the water pipe 3. A water pump 11 is fixedly connected to the end of the quartz sand filter 10 away from the pipe body 4. A first water inlet 14 is fixedly connected to the input end of the water pump 11. A diaphragm 8 is fixedly connected to the side of the pipe body 4 near the central pipe 6. The quartz sand filter 10 is fixedly connected to the side of the second water inlet 13 away from the pipe body 4. The water pump 11 is fixedly connected to the side of the quartz sand filter 10 away from the pipe body 4. The second water inlet 13 is opened on the side of the pipe body 4 away from the central pipe 6. Specifically, in the water purification process, the water pump 11 acts as a power source, driving the raw water through the water pipe 3 to the quartz sand filter 10. With the interception effect of the quartz sand, suspended impurities in the water are effectively removed. The water that has undergone preliminary filtration continues to enter the interior of the central pipe 6 through the water pipe 3 from the inlet 13. Then, it flows evenly into the interior of the pipe body 4 through the water flow holes 7 on the outer wall of the central pipe 6. With the cooperation of the pipe body 4 and the cover 9, the water flow is stably stored. At this time, the remaining water is subjected to the precision filtration of the membrane 8. The tiny suspended particles and large molecular organic matter remaining after the quartz sand filtration are completely intercepted, effectively removing potential pollutants. The interception of large molecular organic matter reduces the possibility of eutrophication and odor generation in the water body, reducing the burden on subsequent disinfection, softening and other treatment stages. The synergistic effect of the two-stage filtration forms a progressive purification mode, which not only gives full play to the pretreatment advantages of quartz sand filtration, but also highlights the deep purification capability of membrane 8 filtration, making the overall purification process more efficient and stable.

[0013] Reference Figures 1-4The ozone recovery assembly 5 includes a blower housing 513, which is fixedly connected to the top of the ozone reaction tank 1. A motor 507 is fixedly connected inside the blower housing 513, and a rotating shaft 508 is fixedly connected to the output end of the motor 507. A fixed column 510 is rotatably connected inside the blower housing 513. Bevel gears 509 are fixedly connected to the top of the rotating shaft 508 and the outer wall of the fixed column 510. Fan blades 511 are fixedly connected to the outer wall of the fixed column 510. The blower housing 513 is also internally... An air filter 512 is fixedly connected to the induced draft fan housing 513. A cyclone separator 501 is fixedly connected to the induced draft fan housing 513 via a water pipe 3. A catalytic tower 505 is fixedly connected to the cyclone separator 501 via a water pipe 3. An air inlet 502 is provided on the side of the cyclone separator 501 near the induced draft fan housing 513. An air outlet 503 is provided on the top of the cyclone separator 501. An air inlet 504 is provided on the bottom of the catalytic tower 505. An air outlet 506 is provided on the side of the catalytic tower 505 away from the air inlet 504. Specifically, during the secondary utilization of residual ozone, motor 507 starts and drives shaft 508 to rotate. Shaft 508 then drives bevel gear 509 to rotate synchronously, thereby causing fixed column 510 and fan blades 511 on its surface to rotate at high speed. Under the power generated by fan blades 511, residual ozone is introduced from ozone reaction tank 1 through water pipe 3 into cyclone separator 501. After entering cyclone separator 501, ozone forms a high-speed rotating airflow inside. With the help of the strong centrifugal force generated by the rotation, particles with a density greater than ozone are thrown against the wall of the separator, achieving separation from ozone. The preliminarily purified ozone then enters through outlet 503. The catalytic tower 505 is in full contact with the catalyst packed inside. For residual ozone that does not directly participate in the reaction, it will be further decomposed or directionally transformed under the activation of the catalyst, thereby achieving efficient utilization, improving resource utilization rate, making full use of residual ozone that might otherwise be wasted, avoiding resource idleness, reducing environmental pollution, and reducing the adverse environmental impact that direct ozone emissions may cause by treating and transforming residual ozone. The combination of centrifugal separation by cyclone separator 501 and catalytic transformation by catalytic tower 505 forms a highly efficient treatment process, making the purification and utilization of ozone more thorough and precise.

[0014] Working principle: When purifying water, the water pump 11 drives the raw water through the water pipe 3 into the quartz sand filter 10 to remove suspended impurities in the water. Then, the water enters the central pipe 6 through the water inlet 13 through the water pipe 3. The water flows into the pipe body 4 through the water outlet 7 on the outer wall of the central pipe 6. The water is stored in the cooperation of the pipe body 4 and the cover 9. The water flowing out is filtered by the membrane 8, which retains the small suspended particles and large organic molecules remaining after the quartz sand filtration, which significantly reduces the turbidity and suspended solids concentration of the water. Motor 507 drives shaft 508 to rotate, shaft 508 drives bevel gear 509 to rotate synchronously, bevel gear 509 drives fixed column 510 and surface fan blade 511 to rotate at high speed. Under the power of fan blade 511, residual ozone is introduced into cyclone separator 501 from ozone reaction tank 1 through water pipe 3. After entering cyclone separator 501, ozone forms a high-speed rotating airflow inside. With the help of the strong centrifugal force generated by rotation, particles with a density greater than ozone are thrown against the wall of the separator to achieve separation. The purified ozone enters catalytic tower 505 through outlet 503 and comes into full contact with the catalyst filled in catalytic tower 505. The residual ozone that does not directly participate in the reaction is further decomposed or directionally transformed under the activation of the catalyst, achieving efficient utilization.
