Description

Technical Field

[0001] This invention relates to the field of environmental water pollution control technology, and in particular to a multifunctional ecological floating island device and purification method for lake water purification. Background Technology

[0002] In recent years, water pollution has become a serious problem in my country, with eutrophication becoming an increasingly prominent issue, particularly in urban lakes. Water pollution not only severely impacts the living environment of surrounding residents but also poses a significant threat to aquatic ecological security. The key to solving the problem of eutrophication in lakes lies in removing algae while simultaneously reducing the levels of nitrogen and phosphorus in the water.

[0003] One of the main methods for lake water treatment at present is aeration technology. Its main principle is to increase the oxygen content and flow of water through artificial aeration. This technology is low-cost, widely applicable, simple to construct, and unlikely to cause secondary pollution. However, aeration technology cannot directly remove algae from polluted water and is mostly used for point source pollution control, with a very limited treatment scope. Ultrasonic technology can effectively remove algae. It mainly uses mechanical force and cavitation effects to generate shock waves, high temperature and pressure, and jets to destroy the structure, function, and biological activity of algal cells. However, the diffusion effect of ultrasound greatly weakens its treatment effect; therefore, it is currently difficult to apply practically to algae treatment in lakes. Summary of the Invention

[0004] The purpose of this invention is to provide a multifunctional ecological floating island device and purification method for lake water purification. The device uses a water pump to provide power to form a large-scale water circulation, which fully mixes the water with air to oxygenate the water. At the same time, an ultrasonic generator placed near the water pipe generates ultrasonic waves to precisely remove algae.

[0005] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: a multifunctional ecological floating island device for lake water purification, comprising a base, a propeller, a solar power supply module, a water pumping and aeration module, and an ultrasonic purification module.

[0006] The base includes a floating plate and multiple frames. The multiple frames are evenly arranged on the upper side of the floating plate, and an installation gap is left between adjacent frames. Landscape plants can be planted on the floating plate, and the plant roots can also play a certain role in phosphorus and nitrogen fixation.

[0007] The solar power supply module includes a solar photovoltaic panel disposed on the upper surface of the frame and a battery pack disposed in the installation gap;

[0008] The thruster is installed in the installation gap and its lower end passes through the float plate. The thruster can propel the device to sail freely on the water surface and go to the water area that needs to be purified for water purification.

[0009] The water pumping and aeration module is installed in the base to circulate the water and fully mix the water with air during the circulation process to oxygenate the water.

[0010] The ultrasonic purification module is installed in the installation gap, and its input end is connected to the output end of the water pumping aeration module for the removal of algae in the circulating water.

[0011] Furthermore, the battery pack is provided in multiple groups and is evenly distributed in the installation gaps.

[0012] Furthermore, the thruster is located below the battery pack.

[0013] Furthermore, the water-lifting aeration module includes a water pump and an air chamber. The input end of the water pump is connected to one end of the main inlet pipe, and the other end of the main inlet pipe is connected to a bottom inlet pipe and a side inlet pipe. The output end of the water pump is connected to one end of the main outlet pipe, and the other end of the main outlet pipe extends from the bottom of the air chamber into the air chamber. The inlet of the bottom inlet pipe is located below the inlet of the side inlet pipe. The inlet of the bottom inlet pipe mainly receives oxygen-deficient lake water from the lower layers, while the side inlet mainly receives surface water containing floating algae. The water flows into the main inlet pipe through each inlet and mixes, flowing to the upper air chamber and fully mixing with the gas in the air chamber. A blower is also installed in the air chamber to ensure full contact between water and air, increasing the dissolved oxygen content in the water. The air chamber is also connected to one end of a water delivery pipe, and the other end of the water delivery pipe is connected to the input end of the ultrasonic purification module. The water lifted by the water pump to the upper air chamber is aerated and then flows out from the water delivery pipe.

[0014] Furthermore, the end of the main water outlet pipe located inside the air chamber is a shower head structure, and its upper end is densely covered with water outlet holes. The water pump disperses the water pumped up into water droplets through the main water outlet pipe, increasing the contact area between water and air.

[0015] Furthermore, the bottom water inlet pipe passes through the center of the float plate at the end away from the main water inlet pipe and extends below it. Multiple side water inlet pipes are provided, and the multiple side water inlet pipes are evenly arranged in the base. The end of the side water inlet pipe away from the main water inlet pipe passes through the side wall of the base, and side water inlet pipes are distributed around the base.

[0016] Furthermore, the inlets of both the bottom and side water inlets are tapered to prevent clogging.

[0017] Furthermore, the horizontal height of the ultrasonic purification module is lower than that of the air chamber, so that the water in the air chamber will flow to the ultrasonic purification module due to gravity. The ultrasonic purification module includes a dedicated housing set in the installation gap. An ultrasonic generator is installed in the dedicated housing. A spiral tube is wound around the outer surface of the ultrasonic generator. One end of the spiral tube is connected to the water supply pipe, and the other end extends out of the dedicated housing. The spiral tube helps to increase the contact area between the water and the ultrasonic waves. The ultrasonic generator continuously generates specific ultrasonic waves, which act on the water in the spiral tube to fully kill the algae.

[0018] Furthermore, the output end of the solar photovoltaic panel is connected to the input end of the battery pack, and the power output end of the battery pack is connected to the power supply ends of the thruster, water pump, blower and ultrasonic generator respectively.

[0019] The present invention also provides a method for purifying lake water, comprising the following steps:

[0020] S1: The ecological floating island device floats on the water surface through the base floating plate. The solar photovoltaic panel converts solar energy into electrical energy and stores it in the battery pack. The battery pack powers the propeller, water pump, blower and ultrasonic generator.

[0021] S2: The water pump starts after being powered on, and draws lake water through the bottom inlet pipe and the side inlet pipe respectively. The drawn lake water is mixed in the main inlet pipe and then sprayed into the air chamber through the main outlet pipe.

[0022] S3: After the blower is powered on, it starts to send outside air into the air chamber. The lake water sprayed out by the main water outlet pipe will mix fully with the air. The mixed lake water will be sent into the ultrasonic purification module through the water supply pipe.

[0023] S4: After the ultrasonic generator in the ultrasonic purification module is powered on, it starts and generates ultrasound. After the lake water in the water supply pipe enters the spiral tube, the ultrasound generated by the ultrasonic generator will remove the algae in the lake water in the spiral tube, thus purifying the algae.

[0024] S5: The output end of the spiral tube will discharge the purified lake water into the lake.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. Based on traditional water aeration technology, this invention introduces an ultrasonic purification device to overcome the shortcoming that water aeration cannot directly destroy algae. By coupling the above technologies, a multifunctional ecological floating island device suitable for lake water purification is designed. This device uses a water pump to provide power to form a large-scale water circulation, which fully mixes the water with air to oxygenate the water. At the same time, an ultrasonic generator placed near the water pipe generates ultrasonic waves to precisely remove algae. The artificial floating island floats on the water surface and can be planted with landscape plants. The plant roots can also play a certain role in phosphorus and nitrogen fixation.

[0027] 2. This device places the ultrasonic generator within the surrounding pipe, which on the one hand increases the contact area between the ultrasonic waves and the water in the pipe to achieve thorough algae removal, and on the other hand enables targeted algae removal from the water, solving the problem of poor algae removal effect caused by diffusion in traditional ultrasonic algae removal technology.

[0028] 3. The energy source of this device is solar energy, which solves the problems of poor mobility and limited function of traditional manual cable power supply. Compared with traditional water purification devices that require external power supply, consume a lot of energy and are difficult to achieve automated continuous operation, this device uses solar energy to achieve energy self-sufficiency and realize the automated operation of the device.

[0029] 4. This device can be used year-round. During algal bloom outbreaks, aeration and ultrasonic purification can effectively inhibit algal growth. During algal bloom outbreaks, the ultrasonic generator can be turned off, and the aeration device can be used for effective prevention. Combined with floating island plant landscape design, it can become a beautiful scenic line in the lake. Attached Figure Description

The thruster 5 can propel the device to sail freely on the water surface and go to the water area that needs to be purified for water purification.

[0044] The water-lifting aeration module is installed in the base to circulate the water and fully mix the water with air during the circulation process, thus oxygenating the water. The water-lifting aeration module includes a water pump 9 and an air chamber 10. The input end of the water pump 9 is connected to one end of the main water inlet pipe 8, and the other end of the main water inlet pipe 8 is connected to a bottom water inlet pipe 6 and a side water inlet pipe 7. The output end of the water pump 9 is connected to one end of the main water outlet pipe 11, and the other end of the main water outlet pipe 11 extends from the bottom of the air chamber 10 into the air chamber 10. The inlet of the bottom water inlet pipe 6 is located below the inlet of the side water inlet pipe 7. The inlet of the bottom water inlet pipe 6 mainly receives oxygen-deficient lake water from the lower bottom layer, while the side water inlet mainly receives surface water containing floating algae. The water flows into the main water inlet pipe 8 through each inlet and mixes with the air in the upper air chamber 10.

The end of the main water outlet pipe 11 located inside the air chamber 10 is a shower head structure, and its upper end is densely covered with water outlet holes. The water pump 9 disperses the pumped water into water droplets through the main water outlet pipe 11, increasing the contact area between water and air. The bottom water inlet pipe 6 passes through the center of the float plate 1 from the end away from the main water inlet pipe and extends below it. Multiple side water inlet pipes 7 are provided, and multiple side water inlet pipes 7 are evenly arranged in the base. The end of the side water inlet pipe 7 away from the main water inlet pipe passes through the side wall of the base. Side water inlet pipes 7 are distributed around the base. The inlets of the bottom water inlet pipe 6 and the side water inlet pipes 7 are conical structures to avoid clogging.

[0045] An ultrasonic purification module is installed in the installation gap 16, and its input end is connected to the output end of the water pumping aeration module. It is used to remove algae from the circulating water. The horizontal height of the ultrasonic purification module is lower than the horizontal height of the air chamber 10. In this way, the water in the air chamber 10 will flow to the ultrasonic purification module due to gravity. The ultrasonic purification module includes a special box 13 installed in the installation gap 16. An ultrasonic generator 14 is installed in the special box 13. A spiral tube 15 is wound around the outer surface of the ultrasonic generator 14. One end of the spiral tube 15 is connected to the water supply pipe 17, and the other end extends out of the special box 13. The spiral tube 15 helps to increase the contact area between the water and the ultrasonic waves. The ultrasonic generator 14 continuously generates specific ultrasonic waves, which act on the water in the spiral tube 15 to fully kill the algae.

[0046] The output end of the solar photovoltaic panel 3 is connected to the input end of the battery pack 4, and the power output end of the battery pack 4 is connected to the power supply ends of the thruster 5, the water pump 9, the blower 12 and the ultrasonic generator 14, respectively.

[0047] The ultrasonic transducer used in the ultrasonic purification module of the above-mentioned ecological floating island device is suitable for large water bodies with a resonant frequency of 20±8KHz, a power of 60W, and a static capacitance of 3800±10%PF; for small water bodies, an ultrasonic vibrating plate with a power of 40W and an ultrasonic frequency of 40KHz can be used.

[0048] The solar power supply module of the above-mentioned ecological floating island device uses monocrystalline silicon solar panels. The material is low-iron tempered velvet glass with a light transmittance of >90%. The external dimensions are 1000×1000×35mm, the voltage is 24V, the power is 600W, and the quantity is 4.

[0049] The solar power module of the above-mentioned ecological floating island device uses a solar-specific gel battery with dimensions of 392×172×215mm, a voltage of 12V, and a capacity of 100AH.

[0050] The above-mentioned multifunctional ecological floating island device uses a high-efficiency, energy-saving, non-clogging water pump 9 with a diameter of 50mm, a flow rate of 15-25m3 / h, a head of 2.2m, a power of 2200W, and a speed of 2800r / min.

[0051] The aforementioned ecological floating island device uses a thin-film microporous aerator in its water-lifting aeration module. The aerator has a diameter of 260 mm and an air flow rate of 1.5-3.0 m³ / h.

[0052] The working principle of this multifunctional ecological floating island device is as follows:

[0053] The ecological floating island device floats on the water surface via a base float plate 1. Solar photovoltaic panels 3 convert solar energy into electrical energy and store it in a battery pack 4. The battery pack 4 powers the propeller 5, water pump 9, blower 12, and ultrasonic generator 14. The water pump 9 starts after being powered on, drawing lake water through the bottom inlet pipe 6 and the side inlet pipe 7. The bottom inlet pipe 6 mainly draws in oxygen-deficient lake water from the lower layers, while the side inlet mainly draws in surface water containing algae. The water flows into the main inlet pipe 8 from each inlet, mixes, and is then sprayed into the air chamber 10 through the main outlet pipe 11. The blower 12... After being powered on, the system starts to send outside air into the air chamber 10. The lake water sprayed from the main water outlet 11 will mix thoroughly with the air, increasing the dissolved oxygen content in the water. The mixed lake water will be sent to the ultrasonic purification module through the water supply pipe 17. The ultrasonic generator 14 in the ultrasonic purification module will start after being powered on and generate ultrasound. After the lake water in the water supply pipe 17 enters the spiral tube 15, the ultrasound generated by the ultrasonic generator 14 will remove the algae in the lake water in the spiral tube 15, thus purifying the algae. The purified lake water will be discharged into the lake from the output end of the spiral tube 15.
