Description

Technical Field

[0001] This utility model relates to the field of seawater desalination, and in particular to a modular seawater desalination device based on light energy diffusion evaporation. Background Technology

[0002] Currently, global seawater desalination technology mainly faces the following technical bottlenecks:

[0003] I. Energy Dependence Issues Existing reverse osmosis (RO) seawater desalination technology requires high-pressure pump sets and precision filter membrane modules, with energy consumption of 3.5-5 kWh / m³ per unit of water produced, and it must rely on a stable power grid. This "energy-consuming water extraction" model is difficult to implement in areas without or with insufficient electricity (such as islands and remote villages), creating a technological paradox of "water extraction is only possible with electricity."

[0004] II. Environmental Impact: Although traditional distillation consumes no mechanical energy, it produces 2-3 liters of concentrated brine for every liter of fresh water produced. Direct discharge of this high-salinity wastewater (salinity of 7-12%) will lead to ecological crises such as destruction of marine communities (osmotic pressure imbalance), soil salinization (conductivity >4000μS / cm), and groundwater pollution.

[0005] Third, the issue of equipment mobility. Most commercially available equipment is a fixed integrated unit, with a single unit generally weighing over 50kg, requiring specialized transport vehicles and technicians for installation and commissioning. In disaster emergency scenarios (such as earthquakes and floods), its response time often lags behind actual needs, creating a passive situation of "equipment waiting for disaster."

[0006] Fourth, the economic issues of operation and maintenance: Reverse osmosis membrane modules require chemical cleaning every 3-6 months (using agents such as sodium hypochlorite), with a single maintenance cost reaching 15-20% of the original value of the equipment. The filter cartridges of distillation equipment need to be replaced even more frequently (1-2 times per month) and require professional operation, leading to the reality that impoverished areas can "afford to buy, but cannot afford to use" them.

[0007] Therefore, it is essential to invent a modular seawater desalination device based on light energy diffusion evaporation. Utility Model Content

The seawater evaporator 2 is suspended and fixedly installed above the inside of the freshwater collector 1 through the steam hood 3. The seawater evaporator 2 is located below the steam hood 3. With this structure, the seawater inside the seawater evaporator 2 can evaporate and come into contact with the steam hood 3, so that the steam is cooled into freshwater on the steam hood 3 and automatically flows into the freshwater collector 1 through the steam hood 3.

[0051] The freshwater collector 1 includes an assembled bracket, a water storage bag 16, and a valve 18. The open-top water storage bag 16 is fixedly installed on the outside of the assembled bracket with hot melt adhesive so that it can be disassembled and assembled for easy storage and carrying.

[0062] Specifically, seawater tank 4 is used to store seawater that needs to be evaporated, and multiple seawater tanks 4 can be set up as needed;

[0063] Specifically, the high-concentration seawater storage container 7 is used to collect the high-concentration seawater generated inside the seawater evaporation storage container 21. For example, when the high-concentration seawater copper-zinc battery 8 does not need the high-concentration seawater temporarily, the high-concentration seawater generated inside the seawater evaporation storage container 21 can be stored in the high-concentration seawater storage container 7 for the high-concentration seawater copper-zinc battery 8 to use as a backup. Multiple high-concentration seawater storage containers 7 can be set up as needed, and corresponding liquid level sensors can be installed inside the high-concentration seawater storage container 7.

[0066] In this embodiment, the prefabricated support includes an upper horizontal support 11, a lower horizontal support 12, a vertical support 13, a fixing block 14, and support legs 15. Several vertical supports 13 are fixedly installed between the upper horizontal support 11 and the lower horizontal support 12 by bolts, so that they can be disassembled, stored, and carried. The upper horizontal support 11, the lower horizontal support 12, and the vertical supports 13 form a frame. Support legs 15 are fixedly installed on the vertical supports 13 by fixing blocks 14, so that the support legs 15 can ensure the overall stability. The water storage bag 16 is sleeved on the outside of the frame. The fixing blocks 14 and the support legs 15 are both located outside the water storage bag 16. The upper horizontal support 11 and the prefabricated support are fixedly connected by metal wires or bolts.

[0067] The upper horizontal support 11, lower horizontal support 12, vertical support 13, fixing block 14 and support leg 15 are all made of aviation aluminum alloy frame;

[0068] Water storage bag 16 is made of waterproof canvas.

[0069] In this embodiment, a water inlet pipe 23 and a water outlet pipe 24 are provided on one side of the seawater evaporation storage container 21, with the water inlet pipe 23 above the water outlet pipe 24.

[0072] In this embodiment, the heat-absorbing structure includes a black heat-absorbing rose 22 and heat-absorbing fins 25 to improve evaporation efficiency. The heat-absorbing rose 22 is coaxially fixedly installed on the bottom surface of the seawater evaporation storage container 21. The heat-absorbing rose 22 is detachably fixedly connected to the main umbrella rod of the umbrella frame 31, such as by threaded connection or bolt connection. The heat-absorbing fins 25 are uniformly fixedly installed on the inner surface of the seawater evaporation storage container 21.

[0073] In this embodiment, the folding frame adopts an aviation aluminum alloy umbrella frame 31 structure. The main umbrella pole of the umbrella frame 31 is detachably fixed to the heat-absorbing structure. The umbrella ribs of the umbrella frame 31 are fixedly connected to the upper horizontal support 11 by bolts or metal wires for easy disassembly and assembly, and also for convenient storage and carrying.

[0074] In this embodiment, the transparent film is a TPU film 32, which is detachably installed on the umbrella frame 31 to form an umbrella structure.

[0075] Specifically, TPU film has high tensile strength and good elastic recovery ability, and can withstand large external forces without deformation.

[0078] Temperature resistance: It can remain stable over a wide temperature range (40℃ to 120℃).

[0079] Waterproof and breathable: TPU film performs excellently and can be used in waterproof clothing, gloves and other protective equipment. It can effectively block water and wind, while also having a certain degree of moisture permeability.

[0080] Biocompatibility: It will not irritate human tissues or cause allergic reactions.

[0081] In this embodiment, pipeline one includes a three-way solenoid valve one 61, a high-concentration seawater transport pipe one 62 and a high-concentration seawater transport pipe two 63. The inlet of the three-way solenoid valve one 61 is fixedly connected to the pumping port of the high-concentration seawater transport pump 6.

[0082] One of the outlets of the three-way solenoid valve 61 is fixedly connected to one end of the high-concentration seawater transport pipe 62, and the other end of the high-concentration seawater transport pipe 62 is fixedly connected to the outlet connection pipe 24.

[0083] The other outlet of the three-way solenoid valve 61 is fixedly connected to one end of the high-concentration seawater transport pipe 63, and the other end of the high-concentration seawater transport pipe 63 is connected to the inside of the high-concentration seawater storage container 7.

[0084] By setting the three-way solenoid valve 61, it is possible to select whether to transport the high-concentration seawater inside the seawater evaporation storage container 21 to the battery compartment of the high-concentration seawater copper-zinc battery 8 or to transport the high-concentration seawater inside the high-concentration seawater storage container 7 to the battery compartment of the high-concentration seawater copper-zinc battery 8, depending on the needs.

[0085] In this embodiment, pipeline two includes a three-way solenoid valve two 64, a high-concentration seawater transport pipe three 65 and a high-concentration seawater transport pipe four 66. The inlet of the three-way solenoid valve two 64 is fixedly connected to the outlet port of the high-concentration seawater transport pump 6.

[0086] One of the outlet ports of the three-way solenoid valve 264 is fixedly connected to one end of the high-concentration seawater transport pipe 365, and the other end of the high-concentration seawater transport pipe 365 is connected to the inside of the high-concentration seawater storage container 7.

[0087] The other outlet port of the three-way solenoid valve 264 is fixedly connected to one end of the high-concentration seawater transport pipe 466, and the other port of the high-concentration seawater transport pipe 466 is connected to the inside of the battery compartment of the high-concentration seawater copper-zinc battery 8.

[0088] By setting the three-way solenoid valve 264, the high-concentration seawater inside the seawater evaporation storage container 21 can be transported to the battery compartment of the high-concentration seawater copper-zinc battery 8 or to the high-concentration seawater storage container 7, depending on the needs.

[0089] In this embodiment, the water storage bag 16 is provided with a pipe hole 17 corresponding to the water inlet connection pipe 23 and the water outlet connection pipe 24, so that the water inlet connection pipe 23 and the water outlet connection pipe 24 can be directly connected to the corresponding low-concentration seawater transport pipe 51 and high-concentration seawater transport pipe 62 through the pipe hole 17, so as to avoid the water storage bag 16 from blocking them and thus reduce the use of pipelines.

[0090] In this embodiment, controller 9 includes a PLC controller, a solar controller, and a wireless alarm module;

[0091] Specifically, level sensor 1, level sensor 2, and seawater concentration sensor are electrically connected to the input terminal of the PLC controller for communication.

[0092] The low-concentration seawater transport pump 5, the high-concentration seawater transport pump 6, the three-way solenoid valve 61 and the three-way solenoid valve 64 are electrically connected to the output terminal of the PLC controller.

[0093] The solar panel 10 charges the high-concentration seawater copper-zinc battery 8 via a solar controller, and the high-concentration seawater copper-zinc battery 8 provides the necessary power for the entire system.

[0094] The PLC controller is used to control the operation of the entire system;

[0095] The wireless alarm module is used to send the device's operating status information to the user's mobile phone.

[0096] Specifically, during use, the low-concentration seawater inside the seawater tank 4 is transported to the seawater evaporation storage container 21 by the low-concentration seawater transport pump 5. When the liquid level sensor 2 above the seawater evaporation storage container 21 is triggered, the low-concentration seawater transport pump 5 stops running. In this way, the low-concentration seawater inside the seawater evaporation storage container 21 will evaporate under the action of the black heat-absorbing rose 22, the heat-absorbing fins 25 and the sun. The evaporated vapor will come into contact with the TPU membrane 32, condense into water on the TPU membrane 32, and drip down the TPU membrane 32 and the umbrella frame 31 into the water storage bag 16 for collection.

[0097] When the seawater concentration inside the seawater evaporation storage container 21 reaches the value set by the seawater concentration sensor, the high-concentration seawater transport pump 6 will be started. The high-concentration seawater transport pump 6 will use the three-way solenoid valve 1 61, the high-concentration seawater transport pipe 1 62, the three-way solenoid valve 2 64, and the high-concentration seawater transport pipe 4 66 to preferentially transport the high-concentration seawater inside the seawater evaporation storage container 21 to the battery compartment of the high-concentration seawater copper-zinc battery 8.

[0098] When the high-concentration seawater copper-zinc battery 8 does not require high-concentration seawater, the high-concentration seawater transport pump 6 will transport the high-concentration seawater inside the seawater evaporation storage container 21 to the high-concentration seawater storage container 7 for temporary storage through the high-concentration seawater transport pipe 1 62, three-way solenoid valve 1 61, three-way solenoid valve 2 64 and high-concentration seawater transport pipe 3 65. This will allow the high-concentration seawater inside the high-concentration seawater storage container 7 to be transported to the battery compartment of the high-concentration seawater copper-zinc battery 8 later through the high-concentration seawater transport pump 6, high-concentration seawater transport pipe 2 63, three-way solenoid valve 1 61, three-way solenoid valve 2 64 and high-concentration seawater transport pipe 4 66.

[0099] When the liquid level sensor 2 at the bottom of the seawater evaporation storage container 21 is triggered, the high-concentration seawater transport pump 6 stops running, and the low-concentration seawater transport pump 5 runs to continue transporting the low-concentration seawater in the seawater tank 4 to the seawater evaporation storage container 21 for evaporation.

[0100] When the liquid level sensor in the water storage bag 16 is triggered, if the valve 18 is selected as a manual valve, the alarm module will send the corresponding information to the user to drain the water. If the water is not drained, the water will automatically overflow from the water storage bag 16.

[0101] If valve 18 is selected as a solenoid valve at this time, the user can set the opening conditions of the solenoid valve, and can set the solenoid valve to be triggered automatically or remotely and manually.

[0102] When the solenoid valve is set to trigger automatically, the alarm module also sends the corresponding information to the user and automatically opens the solenoid valve, thereby draining the water in the water storage bag 16 into the water-using equipment connected to the valve 18.

[0103] When the solenoid valve is set to be triggered remotely and manually, after the user's mobile phone receives the information sent by the alarm module, the user can remotely start the solenoid valve, thereby draining the water in the water storage bag 16 into the water-using equipment connected to the valve 18.

[0104] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
