[0088] Please see Figures 1 to 6 This embodiment relates to a water purification vehicle, including a frame 1, a carriage, and a water purification system, wherein the carriage is fixedly mounted on the frame 1, and the water purification system is mounted inside the carriage;
[0089] The water purification system includes:
[0090] Source water tank 2 is a container used to store water to be treated. It is used to temporarily store various water sources obtained from the outside, such as polluted surface water, groundwater, river water, seawater, etc. Source water tank 2 provides the water to be treated for the entire water purification system. By setting an appropriate volume, it can meet the continuous treatment needs for a certain period of time. The water source for source water tank 2 is supplied by a submersible pump that is powered on (or a water supply truck).
[0091] A temperature detection mechanism 25 is installed inside the source water tank 2. The temperature detection mechanism 25 is used to detect the water temperature inside the source water tank 2 to prevent the water from freezing in low winter temperatures. In this embodiment, the temperature detection mechanism 25 is a temperature sensor.
[0092] A multi-stage filter is provided, which is connected to the source water tank 2 via a pipeline. The water source is filtered and treated through the multi-stage filter, which further purifies the water.
[0093] A source water pump 3 is installed on the pipeline between the multi-stage filter and the source water tank 2; it serves as the power unit for transporting water from the source water tank 2 to the multi-stage filter. The source water pump 3 is a centrifugal pump, which uses a motor to drive an impeller to generate centrifugal force, drawing water from the source water tank 2 and pressurizing it before delivering it to the multi-stage filter. The source water pump 3 provides the power for the water flow within the system, ensuring that the water flows through each stage of the filtration equipment according to the designed path, achieving continuous filtration treatment.
[0094] An ultrafiltration membrane module 9 is connected to the multi-stage filter via a pipeline. The ultrafiltration membrane is a semi-permeable membrane with selective sieving function and a pore size between 0.01 and 0.1 micrometers. In this embodiment, the ultrafiltration membrane module 9 consists of multiple ultrafiltration membrane elements, which are arranged and packaged to form a filtration unit. Utilizing the sieving principle of the membrane, the ultrafiltration membrane module 9 removes impurities such as bacteria, colloids, and large organic molecules from the water, while allowing water molecules and small molecules to pass through, further purifying the water quality and reducing the burden on subsequent reverse osmosis treatment.
[0095] An intermediate water tank 10 is connected to the ultrafiltration membrane module 9 via a pipeline. The intermediate water tank 10 stores the water treated by the ultrafiltration membrane module 9, serving as the water source for subsequent reverse osmosis treatment. In this embodiment, the water in the intermediate water tank 10 is primarily used for domestic water consumption. The intermediate water tank 10 is made of corrosion-resistant material, has a certain volume, and functions as a buffer and storage tank, ensuring the continuity of the reverse osmosis treatment process.
[0096] A heat exchanger 22 is installed in the pipeline between the ultrafiltration membrane module 9 and the multi-stage filter. The heat exchanger 22 exchanges heat with water at a lower temperature (below 5°C) to raise the water temperature. The heat exchanger 22 indirectly heats the water source, avoiding contamination caused by direct contact between the heat source and the water source. The heat exchanger 22 can be a shell-and-tube heat exchanger or a plate heat exchanger.
[0097] A heating mechanism 23 is disposed below the vehicle frame 1 to save space inside the vehicle compartment. Alternatively, in other embodiments, the heating mechanism 23 is disposed inside the vehicle compartment. The heating mechanism 23 and the heat exchanger 22 are connected by a pipeline to form a circulation loop, and the heating mechanism 23 is used to provide a heat source to the heat exchanger 22; wherein the heat source is delivered to the heat exchanger 22 through the heating mechanism 23, and the heat exchanger 22 exchanges heat with the water source in a non-contact manner to increase the water source temperature and ensure that water purification operations can be carried out in low-temperature environments during cold winters.
[0098] The system includes a control mechanism 24, with the temperature detection mechanism 25 electrically connected to the control mechanism 24, and the heating mechanism 23 electrically connected to the control mechanism 24. The control mechanism 24 receives and processes signals from the temperature detection mechanism 25 and controls the start and stop of the heating mechanism 23. The control mechanism 24 includes a PLC controller, a display screen, and an operation panel, with the display screen and operation panel electrically connected to the PLC controller.
[0099] Specifically, in this embodiment of the water purification vehicle, during water purification operation, the source water pump 3 is started, and then the water source is initially filtered through a multi-stage filter. The multi-stage filter gradually removes large particulate impurities, medium particulate impurities, micro particles, organic matter, odors, etc. in the water. Then, it is further filtered through an ultrafiltration membrane module 9, which further removes bacteria, colloids, and other large molecular impurities. The water source filtered by the ultrafiltration membrane module 9 flows through an intermediate water tank 10 for storage. At this time, the water in the intermediate water tank 10 can meet the standards for domestic water use and is available for people to use. During low-temperature operations in cold winter, the temperature detection mechanism 25 monitors the water temperature in the source water tank 2 in real time. When the temperature detection mechanism 25 detects that the water temperature is below 5℃, it sends a signal to the control mechanism 24. After receiving the signal and processing it, the control mechanism 24 controls the heating mechanism 23 to start. The heating mechanism 23 heats the water and delivers the heat source to the heat exchanger 22. The heat exchanger 22 exchanges heat with the water source in a non-contact manner to increase the water source temperature and ensure that water purification operations can be carried out in low-temperature environments during cold winter.
[0100] Optionally, in some embodiments, such as Figures 1 to 6 As shown, the water purification system also includes a freshwater reverse osmosis membrane module 11, a freshwater desalination supply pump 12, and a pure water tank 13. The freshwater reverse osmosis membrane module 11 is connected to the intermediate water tank 10 through a pipeline; the freshwater desalination supply pump 12 is installed on the pipeline between the freshwater reverse osmosis membrane module 11 and the intermediate water tank 10; and the pure water tank 13 is connected to the freshwater reverse osmosis membrane module 11 through a pipeline.
[0101] The freshwater reverse osmosis membrane module 11 is used to filter and purify freshwater sources. The reverse osmosis membrane is a semi-permeable membrane with extremely high filtration precision, typically with a pore size of less than 0.1 nanometers. The freshwater reverse osmosis membrane module 11 consists of multiple reverse osmosis membrane elements. Under pressure, the freshwater reverse osmosis membrane module 11 allows water molecules to permeate through the membrane, while retaining dissolved salts, small organic molecules, heavy metal ions, and other impurities, achieving deep desalination and purification of the water, producing pure water that meets drinking water standards.
[0102] The intermediate desalination water supply pump 12 provides pressure for the water in the intermediate water tank 10 to enter the freshwater reverse osmosis membrane module 11, enabling the water to overcome the resistance of the reverse osmosis membrane and achieve effective filtration and separation.
[0103] The pure water tank 13 is used to store pure water that has been treated by the freshwater reverse osmosis membrane module 11, ensuring that the stored pure water is not contaminated and providing clean drinking water for users.
[0104] Specifically, in this embodiment, when domestic and drinking water are needed during disaster relief operations, the water purification vehicle is driven to the disaster site. During operations, water can be collected locally to treat surface water such as rivers, lakes, and ponds, as well as groundwater. The water to be treated is led to the source water tank 2, and the source water pump 3 is started. Then, the water is initially filtered through a multi-stage filter, which gradually removes large, medium, and small particles, as well as organic matter and odors. After passing through the heat exchanger 22, the water enters the ultrafiltration membrane module 9 for further filtration. The ultrafiltration membrane module 9 further removes bacteria, colloids, and other large molecular impurities. The water filtered by the ultrafiltration membrane module 9 flows through the intermediate water tank 10 for storage. At this time, the water in the intermediate water tank 10 meets the standards for domestic water use and is available for people to use. Next, the freshwater desalination pump 12 is activated, further filtering and purifying the water source through the freshwater reverse osmosis membrane module 11. The reverse osmosis membrane module 11 achieves deep desalination and removes small molecule organic matter, heavy metal ions, etc., ultimately producing purified water that meets drinking water standards. This purified water flows to the pure water tank 13 for storage and is then supplied for public consumption. The combination of multi-stage filters, ultrafiltration membrane module 9, and freshwater reverse osmosis membrane module 11 filters and purifies the water source, effectively addressing various levels of pollution and ensuring the safety and reliability of the purified water for public use and drinking. The water purification system is integrated into the vehicle, forming a mobile water purification vehicle with excellent mobility. In emergencies such as natural disasters or sudden water pollution, it can be quickly transported to the site to rapidly carry out water purification operations, providing clean water to affected people or affected areas, effectively alleviating emergency water supply pressure, and reducing the risk of secondary disasters and public health crises caused by water shortages.
[0105] Optionally, in some embodiments, such as Figures 1 to 6As shown, the water purification system also includes a seawater reverse osmosis membrane module 14, a seawater desalination water supply pump 15, and a seawater desalination high-pressure pump 151. The intermediate water tank 10 includes a primary water tank 101 and a secondary water tank 102. The inlet of the primary water tank 101 is connected to the ultrafiltration membrane module 9 through a pipeline and is used to receive water treated by the ultrafiltration membrane module 9. The outlet of the primary water tank 101 is connected to the inlet of the seawater reverse osmosis membrane module 14 through a pipeline. The seawater desalination water supply pump 15 and the seawater desalination high-pressure pump 151 are respectively arranged in sequence on the pipeline between the primary water tank 101 and the seawater reverse osmosis membrane module 14. The seawater desalination water supply pump 15 is used to supply water to the seawater desalination high-pressure pump 151, and the seawater desalination high-pressure pump 151 is used to pressurize and transport the seawater delivered by the seawater desalination water supply pump 15 to the seawater reverse osmosis membrane module 14, forming a two-stage pressurization for the high salinity of the seawater. The outlet of the seawater reverse osmosis membrane module 14 is connected to the inlet of the secondary water tank 102 via a pipeline. Seawater enters the secondary water tank 102 after being treated by the seawater reverse osmosis membrane module 14. The outlet of the secondary water tank 102 is connected to the inlet of the freshwater reverse osmosis membrane module 11 via a pipeline. The freshwater desalination pump 12 is installed on the pipeline between the secondary water tank 102 and the freshwater reverse osmosis membrane module 11. The outlet of the freshwater reverse osmosis membrane module 11 is connected to the inlet of the pure water tank 13 via a pipeline. In this embodiment, the structure and principle of the seawater reverse osmosis membrane module 14 and the freshwater reverse osmosis membrane module 11 are similar, and will not be described in detail here.
[0106] The water purification vehicle in this embodiment, through a combination of multi-stage filters, ultrafiltration membrane module 9, freshwater reverse osmosis membrane module 11, and seawater reverse osmosis membrane module 14, can filter and purify various types of water sources, including freshwater, brackish water, and seawater. Whether it's water sources suddenly polluted in urban waterworks, surface water or groundwater obtained on-site during field engineering operations, or even seawater from island areas, this water purification vehicle can purify them, greatly expanding the application range of the equipment and solving water problems in different scenarios. Specifically, during operation, water can be taken on-site to treat surface water such as rivers, lakes, and ponds, as well as groundwater and seawater. Seawater is drawn to the source water tank 2, the source water pump 3 is started, and then the water source undergoes preliminary filtration through a multi-stage filter, followed by further filtration through the ultrafiltration membrane module 9. The seawater then sequentially passes through a primary water tank 101, a seawater reverse osmosis membrane module 14, a secondary water tank 102, and a freshwater reverse osmosis membrane module 11, finally entering the pure water tank 13 for storage for human use and drinking.
[0107] Optionally, in some embodiments, such as Figures 1 to 6As shown, the primary water tank 101 is located on one side of the secondary water tank 102. The primary water tank 101 and the secondary water tank 102 are connected by a pipeline, and a connecting valve is installed on the pipeline between the primary water tank 101 and the secondary water tank 102. When treating freshwater, water from the primary water tank 101 can be directly introduced into the secondary water tank 102 through the connecting valve, bypassing the seawater reverse osmosis membrane module 14 treatment stage. When treating seawater, the seawater sequentially passes through the primary water tank 101, the seawater reverse osmosis membrane module 14, the secondary water tank 102, and the freshwater reverse osmosis membrane module 11, finally entering the pure water tank 13. This design enables the water purification vehicle to flexibly treat water sources with different salinities.
[0108] Optionally, in some embodiments, such as Figures 1 to 6 As shown, the water purification system also includes a first backwash pump 16 and an air supply component 17. The first backwash pump 16 is connected to the secondary water tank 102 via a pipeline. The seawater reverse osmosis membrane module 14 and the freshwater reverse osmosis membrane module 11 are respectively connected to the first backwash pump 16 via pipelines. The first backwash pump 16 uses purified water from the secondary water tank 102 to backwash the seawater reverse osmosis membrane module 14 and the freshwater reverse osmosis membrane module 11. During the use of the reverse osmosis membrane, contaminants gradually accumulate on the membrane surface. Backwashing can remove these contaminants, restore the membrane's filtration performance, and extend its service life. Furthermore, the seawater reverse osmosis membrane module 14 and the freshwater reverse osmosis membrane module 11 are respectively connected to the air supply component 17 via pipelines. The air supply component 17 back-blown air into the seawater reverse osmosis membrane module 14 and the freshwater reverse osmosis membrane module 11 to reduce the water content of the seawater and freshwater reverse osmosis membranes, thus protecting them. In this embodiment, the air supply component 17 is an air compressor. Alternatively, in other embodiments, the air supply component 17 is an air storage tank.
[0109] Optionally, in some embodiments, such as Figures 1 to 6As shown, the water purification system further includes a first level gauge 26, a second level gauge 27, and a third level gauge 28; the first level gauge 26 is disposed in the source water tank 2 and is electrically connected to the control mechanism 24, and is used to detect the water level in the source water tank 2; the second level gauge 27 is disposed in the primary water tank 101 and is electrically connected to the control mechanism 24, and is used to detect the water level in the primary water tank 101; The third level gauge 28 is installed in the secondary water tank 102. The third level gauge 28 is electrically connected to the control mechanism 24. The third level gauge 28 is used to detect the water level in the secondary water tank 102. The control mechanism 24 is also used to receive and process the signals sent by the first level gauge 26, the second level gauge 27 and the third level gauge 28, and to control the start and stop of the source water pump 3, the seawater desalination water supply pump 15, the freshwater desalination water supply pump 12 and the seawater desalination high-pressure pump 151.
[0110] Specifically, in this embodiment, the water level in the source water tank 2 is detected in real time by the first level gauge 26, the water level in the primary water tank 101 is detected in real time by the second level gauge 27, and the water level in the secondary water tank 102 is detected in real time by the third level gauge 28. When the first level gauge 26, the second level gauge 27, and the third level gauge 28 detect the set water level, they respectively send signals to the control mechanism 24. After receiving and processing the signals, the control mechanism 24 controls the start of the source water pump 3, the seawater desalination supply pump 15, the freshwater desalination supply pump 12, and the seawater desalination high-pressure pump 151 to supply water. It should be noted that the set water level in this embodiment is set according to actual needs and may vary depending on the size of the tanks and actual requirements.
[0111] Optionally, in some embodiments, such as Figures 1 to 6 As shown, the heating mechanism 23 includes a heating water tank 231 and a heater 232. The heating water tank 231 is connected to the heater 232, and the heater 232 is connected to the heat exchanger 22 via a pipeline. The heat exchanger 22 is also connected to the heating water tank 231 via a pipeline. The heating water tank 231 stores the heat exchange medium water and supplies it to the heater 232. The heater 232 heats the heat exchange medium water, and the heated water is then transported to the heat exchanger 22. The heat exchanger 22 performs non-contact heat exchange with the water source to increase the water source temperature. Afterward, the heated heat exchange medium water flows back from the heat exchanger 22 to the heating water tank 231, thus circulating to ensure that water purification operations can be performed in cold winter environments.
[0112] Optionally, in some embodiments, such as Figures 1 to 6 As shown, the multi-stage filter includes a disc filter 4, a bag filter 5, and a titanium rod filter 6. The disc filter 4, the bag filter 5, and the titanium rod filter 6 are sequentially arranged on the pipeline between the source water pump 3 and the ultrafiltration membrane module 9.
[0113] Disc filter 4 is a filter that uses disc filter elements for filtration. Structurally, it has multiple stacked discs inside, with fine grooves on the surface of the discs forming filtration channels. Disc filter 4 performs coarse filtration, removing large particulate impurities such as silt and rust from the water, and can trap larger suspended solids, providing initial protection for subsequent filtration equipment. Specifically, in this embodiment, disc filter 4 can be switched via a valve, using the source water pump 3 as a power source, and backwashing is performed using water from the source water tank 2.
[0114] Furthermore, the bag filter 5 consists of a filter bag and a filter housing. The filter bag is made of materials such as polyester and polypropylene and comes in different filtration precision specifications. Its function is to further remove medium-sized particulate impurities from the water, intercepting particles with a diameter of generally 5 micrometers and above, effectively filtering suspended solids and colloids in the water, reducing water turbidity, and providing a guarantee for subsequent finer filtration. The filter bag can be replaced periodically.
[0115] Furthermore, the titanium rod filter 6 uses titanium rods as the filter medium, which possess characteristics such as high strength, corrosion resistance, and high temperature resistance. Its structure involves the titanium rods being installed inside the filter housing, with water flowing through the micropores of the titanium rods for filtration. Through fine filtration using the titanium rod filter 6, particles with smaller diameters, typically around 0.2 microns, can be trapped, effectively removing bacteria, some viruses, and tiny suspended solids from the water, further purifying the water quality.
[0116] Optionally, in some embodiments, such as Figures 1 to 6 As shown, the multi-stage filter also includes an activated carbon filter 7, which is disposed in the pipeline between the titanium rod filter 6 and the ultrafiltration membrane module 9. The activated carbon filter 7 is filled with activated carbon, which has a rich pore structure and a large specific surface area. The activated carbon filter 7 adsorbs residual chlorine, organic matter, odors, and some pigments in the water, improving the taste and odor of the water. It also removes some small-molecule organic matter from the water, creating better conditions for subsequent membrane treatment.
[0117] Optionally, in some embodiments, such as Figures 1 to 6As shown, the water purification system also includes a second backwash pump 8. The intermediate water tank 10 is connected to the activated carbon filter 7 via a pipeline, and the second backwash pump 8 is installed on the pipeline between the intermediate water tank 10 and the activated carbon filter 7. The second backwash pump 8 uses water from the intermediate water tank 10 to backwash the activated carbon filter 7. During use, the activated carbon filter 7 gradually accumulates contaminants. Backwashing removes these contaminants, restores the filtration performance of the activated carbon filter 7, and extends its service life.
[0118] Optionally, in some embodiments, such as Figures 1 to 6 As shown, the water purification system also includes a domestic water supply pump 18 and a drinking water supply pump 19. The domestic water supply pump 18 is connected to the intermediate water tank 10 via a pipeline. The domestic water supply pump 18 is used to transport water from the intermediate water tank 10 to domestic water usage points, such as washing and cleaning. Since the water in the intermediate water tank 10 has been treated by the ultrafiltration membrane module 9, most impurities and microorganisms have been removed, which can meet the basic needs of domestic water use. At the same time, there is no need for reverse osmosis treatment, saving energy and costs. Furthermore, the drinking water supply pump 19 is connected to the pure water tank 13 via a pipeline. The drinking water supply pump 19 transports the purified water in the pure water tank 13 to drinking water usage points, such as direct drinking and cooking. The water in the pure water tank 13 has undergone reverse osmosis treatment, and the water quality meets drinking water standards, which can ensure the safety of users' drinking water. Both the domestic water supply pump 18 and the drinking water supply pump 19 are constant pressure pumps, which can maintain the water pressure in the pipeline within a fixed constant range to ensure that water can be used at any time.
[0119] Optionally, in some embodiments, such as Figures 1 to 6 As shown, the water purification vehicle also includes a power generation mechanism 20, which is located inside the vehicle compartment. The power generation mechanism 20 generates electricity to supply power to the water purification system or to the outside environment. This mechanism is a diesel generator. The diesel generator provides power to the water purification equipment, including the motors for the drive pump 3, freshwater desalination pump 12, seawater desalination pump 15, seawater desalination high-pressure pump 151, first backwash pump 16, second backwash pump 8, and air supply component 17, as well as controlling the operation of the equipment. Furthermore, it can also supply power to the outside environment, meeting the power needs of other equipment in field operations and other scenarios, thus enhancing the independent operation capability and applicability of the water purification vehicle.
[0120] Optionally, in some embodiments, such as Figures 1 to 6As shown, the water purification vehicle also includes a bag packaging machine 21, which is installed inside the vehicle compartment. The bag packaging machine 21 is used to package purified water into individual bags. In emergency rescue, disaster relief, field operations, and other scenarios, the packaged water is easy to transport and distribute, making it convenient for people to obtain and use, thus improving the convenience and safety of purified water.
[0121] The water purification vehicle in this embodiment can draw water locally based on the conditions at the disaster site and filter and purify various types of water sources, including freshwater, brackish water, and seawater. It is primarily used for both freshwater desalination and seawater desalination. Details are as follows:
[0122] Freshwater desalination mode: When the "freshwater purification" mode is turned on, the submersible pump is powered on and started (or the water supply truck starts supplying water). Once the water level in the source water tank 2 reaches the set height, the source water pump 3 starts, and the rear disc filter 4 starts accordingly. The source water passes through the disc filter, bag filter 5, titanium rod filter 6, and then enters the activated carbon filter 7. After being filtered by the activated carbon filter 7, the water passes through the heat exchanger 22 and enters the ultrafiltration membrane module 9. After passing through the ultrafiltration membrane module 9, it enters the primary water tank 101 and the secondary water tank 102 (at this time, the primary water tank 101 and the secondary water tank 102 are opened through the intermediate connecting valve, making the water tanks into one tank). When the water level meets the demand, the freshwater desalination supply pump 12 is turned on, and the water flows through the freshwater reverse osmosis membrane module 11 to purify the terminal water supply. The purified pure water enters the pure water tank 13 for storage and standby. When the water level in the pure water tank 13 is sufficient, the drinking water supply pump 19 starts, which can keep the water pressure in the pipeline within a fixed constant range to ensure that water is available at any time; when the water level in the intermediate water tank 10 is sufficient, the domestic water supply pump 18 also starts, which can keep the water pressure in the pipeline within a fixed constant range to ensure that domestic water is available at any time.
[0123] Seawater desalination mode: When the "seawater desalination" mode is turned on, the submersible pump is powered on and started (or the water supply truck starts supplying water). When the water level in the source water tank 2 reaches the set height, the source water pump 3 starts, and the rear disc filter 4 starts accordingly. The source water passes through the disc filter, bag filter 5, titanium rod filter 6, and then enters the activated carbon filter 7. After being filtered by the activated carbon filter 7, the water passes through the heat exchanger 22 and enters the ultrafiltration membrane module 9. Then, when the water level in the primary water tank 101 meets the water supply requirements, the seawater desalination water supply pump 15 and the seawater desalination high-pressure pump 151 are turned on in sequence. The water flows through the seawater reverse osmosis membrane module 14 for seawater desalination treatment. The treated purified water enters the secondary water tank 102. When the water level in the secondary water tank 102 meets the requirements, the freshwater desalination water supply pump 12 is turned on. The water flows through the freshwater reverse osmosis membrane module 11 for secondary purification. The purified pure water enters the pure water tank 13 for storage and standby. When the water level in the pure water tank 13 is sufficient, the drinking water supply pump 19 starts, which can keep the water pressure in the pipeline within a fixed constant range to ensure that water is available at any time; when the water level in the intermediate water tank 10 is sufficient, the domestic water supply pump 18 also starts, which can keep the water pressure in the pipeline within a fixed constant range to ensure that domestic water is available at any time.
[0124] Unlike existing technologies, the water purification vehicle in this embodiment has the following beneficial effects:
[0125] This water purification vehicle, through a combination of multi-stage filters, an ultrafiltration membrane module 9, a freshwater reverse osmosis membrane module 11, and a seawater reverse osmosis membrane module 14, can treat various types of water sources, including freshwater, brackish water, and seawater. Whether it's water sources suddenly contaminated at urban water treatment plants, surface water or groundwater obtained on-site during field engineering operations, or even seawater from island regions, all can be purified using this vehicle, greatly expanding the equipment's application range and solving water problems in different scenarios.
[0126] Excellent purification effect: The multi-stage filter gradually removes large, medium, and small particulate impurities, as well as organic matter and odors from the water; the ultrafiltration membrane module 9 further removes bacteria, colloids, and other large molecular impurities; the reverse osmosis membrane module achieves deep desalination and removes small molecular organic matter and heavy metal ions, ultimately producing pure water that meets drinking water standards. This combination of multi-stage filtration and membrane separation technology can effectively cope with water sources of various levels of pollution, ensuring the safety and reliability of the purified water.
[0127] Intelligent water temperature monitoring: During low-temperature operations in cold winter, the water temperature in the source water tank 2 is monitored in real time by the temperature detection mechanism 25. When the temperature detection mechanism 25 detects that the water temperature is below 5℃, the temperature detection mechanism 25 sends a signal to the control mechanism 24. After receiving the signal, the control mechanism 24 identifies and processes it, and then controls the heating mechanism 23 to start. The heating mechanism 23 heats the water and delivers the heat source to the heat exchanger 22. The heat exchanger 22 exchanges heat with the water source in a non-contact manner to increase the water source temperature and ensure that water purification operations can be carried out in low-temperature environments during cold winter.
[0128] Extending component lifespan: The backwashing system, consisting of the backwash pump and air supply component 17, can regularly clean the reverse osmosis membrane module, remove contaminants from the membrane surface, restore the membrane's filtration performance, extend the membrane's lifespan, and reduce equipment maintenance costs and membrane element replacement frequency.
[0129] Separate water supply system is energy-efficient and highly effective: The installation of domestic water supply pump 18 and drinking water supply pump 19 enables separate supply of domestic and drinking water. Domestic water only needs to be treated by the ultrafiltration membrane module 9 to meet demand, eliminating the need for reverse osmosis and saving energy. Drinking water, after reverse osmosis treatment, meets high-quality standards, ensuring user health. This separate water supply model improves water resource utilization efficiency and reduces operating costs.
[0130] High mobility and emergency response capability: The water purification equipment is integrated into the vehicle compartment, forming a mobile water purification truck with excellent mobility. In emergencies such as natural disasters or sudden water source pollution, it can be quickly transported to the scene to rapidly carry out water purification operations, providing clean water to affected people or affected areas, effectively alleviating emergency water supply pressure, and reducing the risk of secondary disasters and public health crises caused by water shortages. Meanwhile, the configuration of the power generation unit 20 and the bag packaging machine 21 further enhances the independent operation and water supply capability of the water purification truck in the field and emergency scenarios.
