Description

Technical Field

[0001] This invention relates to the field of water treatment technology, specifically to a high-efficiency dissolved air device based on an air flotation system. Background Technology

[0002] Water treatment methods include physical and chemical treatment. Humans have been treating water for many years. Physical methods involve using filter media with different pore sizes to remove impurities from the water through adsorption or barrier methods. Activated carbon is a significant adsorption method, while barrier methods involve passing water through filter media to prevent larger impurities from passing through, thus obtaining cleaner water. Dissolved air flotation (DAF) is another commonly used water treatment method. DAF generates a large number of microbubbles in the water, causing air to adhere to suspended particles in the form of highly dispersed microbubbles, creating a density less than water. Utilizing buoyancy, these particles float on the surface, achieving solid-liquid separation. DAF is classified into ultra-efficient shallow DAF, vortex DAF, and horizontal flow DAF, and is currently used in water supply, industrial wastewater, and municipal sewage treatment. The advantages of DAF include low investment, small footprint, high automation, and convenient operation and management. Within a DAF system, the dissolved air device is a particularly important component.

[0003] However, the dissolved air devices currently available on the market have too many components, and their operation results in high power consumption and low efficiency, leading to low utilization of water dissolved in gas and failing to meet current usage requirements.

[0027] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use.

[0028] 1. The system consists of a dissolved air tank, inlet pipe, water pump, outlet pipe, suction chamber, dissolved air nozzle, and dissolved air pipe. The inlet pipe draws treated return water from the flotation tank into the dissolved air tank. The water in the inlet pipe is then sprayed at high speed into the suction chamber by a micro-nano bubble generator, creating negative pressure that draws in gas from the injection chamber. The gas and water mix and then enter the dissolved air nozzle at high speed, undergoing rapid and intense energy exchange. This causes water and air molecules in the dissolved air nozzle to simultaneously move at high speed, separating and splitting, pulverizing the air into tiny charged bubbles. These bubbles then enter the dissolved air pipe, where kinetic energy is converted into potential energy, further rapidly compressing the bubbles and increasing the solubility of air in water. Finally, the dissolved air water is evenly distributed to the flotation tank through the outlet pipe. The depressurization and release process within the tank allows dissolved air to precipitate out in the form of micro-nano bubbles. These bubbles have a high surface area and adsorption capacity, effectively removing suspended solids from wastewater of varying concentrations. The dissolved air is released from the water, forming a microbubble layer with micro-nano particle sizes. This microbubble layer intercepts and filters suspended solids in the wastewater, significantly improving the hydraulic load of the flotation process. The intercepted suspended solids rise to the water surface, forming a large amount of scum, which is then removed by a chain-type scum remover installed on the flotation tank. This process achieves the desired treatment effect, reduces the manufacturing cost of the dissolved air process, and lowers the equipment cost of the dissolved air portion of the entire flotation system. Consequently, it reduces the basic energy consumption required for the dissolved air process and ensures the stability of the dissolved air efficiency.

[0029] 2. The gas-water mixing and regulating mechanism allows for adjustment of the gas pressure and total gas volume within the injection chamber, ensuring its airtightness and preventing leakage. Furthermore, the disassembly block can be removed from the mounting slot for easy removal and replacement of the disassembly block and one-way valve, facilitating the adjustment of the gas dissolving rate during use. Combined with the operation of the gas injection pump, the adjustment of the gas pressure and total gas volume within the injection chamber enables multi-faceted adjustment of the gas dissolving rate, increasing the convenience of gas dissolving adjustment during the use of this high-efficiency gas dissolving device.

[0030] 3. The sound-absorbing sealing protection mechanism allows the sound-absorbing cotton pad to absorb the sound during the use of the dissolved gas tank, and also provides dry protection for the inside of the dissolved gas tank, preventing corrosion caused by moisture. It also prevents moisture from seeping into the sound-absorbing cotton pad, thus improving its sound absorption performance. Furthermore, the contact pipe provides contact protection to the outside of the outlet pipe, ensuring elastic contact between the outlet pipe and the dissolved gas tank, preventing noise caused by vibration. This also improves the sealing at the connection between the outlet pipe and the dissolved gas tank. The contact pipe can also be removed from the embedded sleeve for replacement, facilitating sound absorption and enhancing the sealing performance of the high-efficiency dissolved gas device during use.

[0031] 4. The buffer installation mechanism allows the mounting plate to be installed with bolts to the flotation tank. When the dissolved air tank vibrates, the sliding seat moves within the receiving trough, causing the spring telescopic rod to contract. Simultaneously, the through rod moves relative to the mounting seat, causing the buffer spring to contract. A limiting plate can be used to limit the movement between the sliding seat and the mounting seat, thus providing elastic buffer protection between them. This prevents vibrations caused by the internal water flow of the dissolved air tank from affecting the stable installation between the dissolved air tank and the flotation tank, increasing the buffer protection after installation.

[0059] Working Principle: When using this high-efficiency dissolved air device based on an air flotation system, firstly, the dissolved air tank 2 is installed at one end of the air flotation tank 1, and the water pump 5 and the outlet pipe 6 are connected to the air flotation tank 1. With the water pump 5 running, the treated return water from the air flotation tank 1 is pumped into the dissolved air tank 2 through the inlet pipe 4. The water in the inlet pipe 4 is then sprayed at high speed into the suction chamber 7 by the action of a micro-nano bubble generator, creating a negative pressure in the suction chamber 7. This draws in the gas from the injection chamber 1105. After the gas and water mix, they enter the dissolved air tube nozzle 8 at high speed, undergoing rapid and intense energy exchange. This causes water molecules and air molecules in the dissolved air tube 9 to simultaneously move at high speed, separating and splitting, pulverizing the air into tiny electrical charges. Air bubbles are loaded and then enter the dissolved air pipe 9, where kinetic energy is converted into potential energy, further rapidly compressing the bubbles and increasing the solubility of air in water. The dissolved air water is then evenly released into the flotation tank 1 through the outlet pipe 6 under reduced pressure. The air dissolved in the water is released in the form of micro-nano bubbles, which have a high surface area and adsorption capacity, and can effectively remove suspended solids from wastewater of different concentrations. The air dissolved in the water is released from the water to form a micro-bubble layer with a particle size of micro-nano. The micro-bubble layer intercepts and filters suspended solids in the wastewater, greatly improving the hydraulic load of the flotation. The intercepted suspended solids rise to the water surface, forming a large amount of scum, which is then removed by the chain scum remover installed on the flotation tank 1, achieving the treatment effect.

[0060] This high-efficiency dissolved air device based on an air flotation system can inject gas into the injection chamber 1105 by operating the air injection pump 1101. This allows for regulation of the air pressure and total gas volume within the injection chamber 1105. Combined with the installed placement ring 1102, sealing side plate 1103, and sealing gasket 1104, the airtightness of the injection chamber 1105 is ensured, preventing leakage. Furthermore, when moisture is injected into the suction chamber 7 through the micro-nano bubble generator, the gas in the injection chamber 1105 will... The one-way valve 1108 enters the suction chamber 7. When not in use, the side cover 3, the placement ring 1102 and the sealing side plate 1103 can be disassembled and removed. The disassembly block 1107 can be taken out from the mounting groove 1106. The disassembly block 1107 and the one-way valve 1108 can be disassembled and replaced, which facilitates the adjustment of the dissolved gas rate when the high-efficiency dissolved gas device is used. Combined with the operation of the gas injection pump 1101, the gas pressure and total gas volume inside the gas injection chamber 1105 can be adjusted, which can effectively adjust the dissolved gas rate of the dissolved gas tank 2, increasing the convenience of dissolved gas adjustment when the high-efficiency dissolved gas device is used.

[0061] When in use, this high-efficiency dissolved air device based on an air flotation system utilizes the sound-absorbing cotton pad 1204 on the inner wall of the dissolved air tank 2 to absorb sound during operation. By disassembling the drying box 1208 inside the plate 1207, and combining the vent holes 1209 inside the drying box 1208 with the desiccant powder pack 1210 inside, the interior of the dissolved air tank 2 can be dried and protected, preventing corrosion caused by moisture. It also prevents moisture from seeping into the sound-absorbing cotton pad 1204, thus maintaining its sound absorption effect and increasing the efficiency of the device. The sound-absorbing protection performance during use is achieved through the embedded sleeve 1205 and contact pipe 1206 on the outside of the water outlet pipe 6. The contact pipe 1206 can be used to protect the outside of the water outlet pipe 6, thereby making elastic contact between the water outlet pipe 6 and the dissolved gas tank 2. This avoids noise caused by vibration between the water outlet pipe 6 and the dissolved gas tank 2, and also improves the sealing performance at the connection between the water outlet pipe 6 and the dissolved gas tank 2. The contact pipe 1206 can also be removed from the embedded sleeve 1205 for replacement, which facilitates the sound-absorbing protection during the use of this high-efficiency dissolved gas device and increases the sealing performance of the high-efficiency dissolved gas device during use.

[0062] When installing the dissolved air tank 2 between the dissolved air tank 2 and the flotation tank 1, the mounting plate 1308 can be installed between the mounting plate 1308 and the flotation tank 1 using bolts. When the dissolved air tank 2 vibrates, the sliding seat 1304 will move within the receiving groove 1302, causing the spring telescopic rod 1303 to contract. At the same time, the through rod 1305 will move relative to the mounting seat 1301, causing the buffer spring 1306 to contract. The limiting plate 1307 can be used to limit the movement between the sliding seat 1304 and the mounting seat 1301, thereby providing elastic buffer protection between the mounting seat 1301 and the sliding seat 1304. This prevents the dissolved air tank 2 from vibrating due to the internal water flow, which could affect the stable installation between the dissolved air tank 2 and the flotation tank 1, and increases the buffer protection after the installation of the dissolved air tank 2 and the flotation tank 1.
