Description

Technical Field

[0001] The utility model relates to the field of ecological restoration of lakes and reservoirs, and in particular to a liquid-gas energy water-lifting aeration purification device. Background Art

[0002] Reservoirs and lakes are important water storage resources and integral parts of ecosystems. However, due to human activities and natural factors, reservoirs and lakes have become polluted, causing a decrease in dissolved oxygen levels and the lower water bodies to become hypoxic or anaerobic. In these situations, aeration technology is used to improve the oxygen supply in the water and promote biodegradation and purification processes.

[0003] The application of aeration technology can have multiple benefits. First, aeration can increase the dissolved oxygen content in water, promote the growth and activity of aerobic microorganisms in the water, and accelerate the degradation of organic pollutants. Second, aeration can reduce the concentration of pollutants such as chemical oxygen demand (COD), ammonia nitrogen (NH3-N), and total nitrogen (TN) in water, thereby improving water quality. In addition, aeration can oxidize compounds that cause odors and harmful substances, improving the odor and appearance of water.

[0004] Lifting aeration utilizes naturally compressed air masses to propel liquid upward, achieving an exchange between upper and lower water bodies. It is particularly suitable for deep lakes and reservoirs. It is primarily used to improve water quality, control algae growth, increase dissolved oxygen, and reduce pollutants in sediments. When a lift aeration system is operating, air forms bubbles in the water. When the bubbles grow to a certain size, they rise rapidly, creating a siphon effect, sucking in the water below. The bubbles flow upward with increasing speed, forming air bubbles that rise to the surface and rush out of the outlet of the guide tube, achieving air-water mixing.

[0005] Existing water-lifting aeration devices can achieve water mixing and improve water quality during use. However, they operate through a siphon effect, limited by the capacity of the air mass storage tank. The amount of gas delivered at a time is limited, and the operating intensity cannot be adjusted. To increase the operating intensity, an oversized air storage tank is often required, resulting in a large aeration head that is difficult to install and, once installed, virtually impossible to move. Furthermore, the siphonic operation of water-lifting aeration requires a high-power blower and a machine room, forcing it to be installed near the shore. Gas is transported through long pipelines, which inevitably lead to leaks and waste. The oversized and heavy aeration head and the construction of a machine room near the shore require not only pipeline construction but also land acquisition, resulting in high construction costs, a long construction period, and high operating costs.

[0006] In summary, for the ecological management of lakes and reservoirs, water-lifting aeration devices can quickly achieve water mixing and oxygenation. There is a particular need for a liquid-gas-powered water-lifting aeration purification device to address the shortcomings of existing water-lifting aeration devices, overcoming the difficulties of installation, mobility, and the inability to adjust gas volume and operating intensity. Furthermore, it addresses the practical difficulties of requiring land, long construction periods, and high costs. To this end, we propose a liquid-gas-powered water-lifting aeration purification device. Summary of the Invention

[0007] The purpose of the utility model is to provide a liquid-gas water-lifting aeration purification device to solve the problems raised in the above background technology.

[0008] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0009] A liquid-gas water-lifting aeration purification device includes a floating platform, a pulse air supply system, a gas releaser, a water-lifting cylinder, and a power supply and control system. The pulse air supply system and the power supply and control system are mounted on the floating platform. The gas releaser and the water-lifting cylinder form a module, which is suspended below the floating platform and can be moved up and down to adjust the depth.

[0010] Furthermore, the floating platform is a floating frame structure, which is composed of a float, a bracket, and a bearing platform. It can bear the weight of all components and the weight of installation and maintenance personnel, and can be moved according to needs.

[0011] Furthermore, the pulse air supply system is composed of a box, a high-pressure fan, a high-pressure gas tank, a solenoid valve, and a high-pressure air pipe; the high-pressure fan is controlled to open and close by the pressure gauge on the high-pressure gas tank to supply pressurized air to the high-pressure gas tank; the solenoid valve is controlled to open and close by a pressure gauge or a time-controlled switch; the high-pressure air pipe connects the solenoid valve and the air inlet of the gas releaser.

[0012] Furthermore, the gas releaser is installed at the lower part of the water lifting cylinder, and the release head is installed inside the guide cylinder and is connected to the external air inlet through a pipeline.

[0013] Furthermore, the length of the guide tube of the water-lifting cylinder is adjustable, a guide water distribution plate is set at the top, and a trumpet water inlet is set at the bottom. The reinforcement sleeve is pulled by a suspension chain and suspended on the floating platform, and the stabilizing anchor stone is suspended below the trumpet water inlet through a stabilizing rope.

[0014] Furthermore, the power supply and control system is powered by solar energy or municipal power.

[0015] Compared with existing technologies, the present invention offers the following advantages: novel design, stable structure, convenient installation, removable position, and wide application range. The integrated floating platform facilitates equipment installation and operation and maintenance, and its mobility expands its usable area, thereby reducing construction difficulty and the cost of lake and reservoir management. The equipment adopts a pulsed working mode, with adjustable gas volume. The kinetic energy air mass formed by rapid exhaust has a higher mixing intensity with the water body, resulting in a stronger oxygenation effect and a wider range of applications. The top diversion water distribution plate changes the water flow direction, increasing the contact time between the gas and the water flow, thereby improving the oxygenation effect.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0022] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 A liquid-gas water-lifting aeration purification device includes a floating platform 1, a pulse air supply system 2, a gas releaser 3, a water-lifting cylinder 4, and a power supply and control system 5, which constitute the liquid-gas water-lifting aeration purification device; the pulse air supply system 2 and the power supply and control system 5 are installed on the floating platform 1; the gas releaser 3 and the water-lifting cylinder 4 form a module, which is suspended below the floating platform 1 and can be moved up and down to adjust the depth.

[0023] In addition, the floating platform 1 is a floating frame structure, which is composed of a float 1-1, a bracket 1-2, and a carrying platform 1-3. It can bear the weight of all components and the weight of installation and maintenance personnel, and move its position according to needs.

[0024] In addition, the pulse air supply system 2 is composed of a box 2-1, a high-pressure fan 2-2, a high-pressure gas tank 2-3, a solenoid valve 2-4, and a high-pressure gas pipe 2-5; the high-pressure fan 2-2 is controlled to open and close by the pressure gauge on the high-pressure gas tank 2-3, and pressurizes the gas to the high-pressure gas tank 2-3; the solenoid valve 2-4 is controlled to open and close by a pressure gauge or a time-controlled switch; the high-pressure gas pipe 2-5 connects the solenoid valve 2-4 and the air inlet 3-2 of the gas releaser 3.

[0025] In addition, the gas releaser 3 is installed at the lower part of the water lifting cylinder 4, and the release head 3-1 is installed inside the guide cylinder 4-3 and is connected to the external air inlet 3-2 through a pipeline.

[0026] In addition, the length of the guide tube 4-3 of the water-lifting cylinder 4 is adjustable, a guide water distribution plate 4-1 is set at the top, and a trumpet water inlet 4-4 is set at the bottom. The reinforcement sleeve 4-2 is pulled by the suspension chain 4-5 and suspended on the floating platform 1, and the stabilizing anchor stone 4-7 is suspended below the trumpet water inlet 4-4 through the stabilizing rope 4-6.

[0027] In addition, the power supply and control system 5 is powered by solar energy or municipal power.

[0028] The utility model injects compressed air into the high-pressure gas storage tank 2-3 through the high-pressure fan 2-2, and then releases a certain amount of compressed air through the solenoid valve 2-4. The compressed air quickly reaches the air inlet 3-2 of the gas releaser 3 along the high-pressure air pipe 2-5, and then is released through the release head 3-1 to form a high-pressure air mass 6, which then rises along the guide tube 4-3 of the water lifting tube 4, while continuously expanding its volume to exchange mass and transfer dissolved oxygen with the water body, and finally diffuses from the guide water distribution plate 4-1 to the surrounding areas of the water surface in the form of radial flow, forming an aerated water flow ring.

[0029] This utility model instantly releases a fixed amount of compressed air to form a high-pressure air mass, causing air and water to mix instantly, dissolving the oxygen in the air into the water and then diffusing it to the surrounding water. Simultaneously, the water body forms an upward and downward circulation, achieving the dual functions of aeration and water circulation. Furthermore, the device utilizes an integrated floating structure for portability; the amount of compressed air released is adjustable, adapting to varying water quality requirements; and the water pumping cylinder can be adjusted in length to suit the water depth. Combining the platform's portability, the adjustable amount of compressed air, and the adjustable water pumping cylinder length allows a single device to cover a wider area, resulting in superior practical performance and a wide range of applications.

[0030] The beneficial effects of this utility model are: novel design, stable structure, convenient installation, movable position, and wide range of applications. The integrated floating platform is convenient for equipment installation and operation and maintenance, and its mobility expands its usable area, thereby reducing the construction difficulty and the cost of lake and reservoir management. The equipment adopts a pulsed working mode, the gas volume can be adjusted, and the kinetic energy air mass formed by rapid exhaust has a higher mixing intensity with the water body, which has a stronger oxygenation effect and a wider range of applications. The top diversion water distribution plate changes the water flow direction, so that the gas and water flow have a longer contact time, improving the oxygenation effect.
