Description

Mobile green energy water purification device and water purification method thereof

This disclosure relates to a mobile green energy water purification device and a water purification method thereof.

In remote or high-altitude areas, residents usually use well water or mountain spring water directly for drinking without any water purification or disinfection. However, when encountering a storm or other natural disasters, the raw water is in poor condition or the water supply is insufficient, which will cause water shortage. In addition, in remote areas of some underdeveloped countries, people often drink untreated raw water directly, which may not only cause serious gastrointestinal diseases in the long run, but also affect physical health and may even threaten life. Therefore, being able to provide safe and hygienic drinking water in a long-term and stable manner is an important key to improving the quality of life and maintaining health.

The commonly used water purification method at present is to use chemicals for pre-coagulation and sedimentation treatment. Although this water purification method can provide a large amount of drinking water in a relatively small area, it will also produce a large amount of chemical sludge. Not only that, how to remove and treat this chemical sludge in an environmentally friendly way is even more difficult.

In addition, in some remote areas of underdeveloped countries, there is often no sound power system, which cannot supply stable and sufficient electricity for some water purification devices with large power demand (such as reverse osmosis and ion exchange). Due to the remote location, it is difficult for technical personnel to frequently go to the site for treatment, making it difficult for the water purification device to play its normal role and difficult to perform routine maintenance and care.

In view of this, water purification equipment and water purification methods that can be easily moved to disaster areas, remote areas, high altitudes or backward areas have been developed. After obtaining the water source, safe and hygienic drinking water can be produced immediately. No chemical agents are used for pre-coagulation and sedimentation treatment during the water purification process, and no chemical sludge is generated. The water purification equipment is driven by green energy and is not affected by local power supply shortages. It also has remote monitoring and automatic operation functions. It is what the people in these areas have long been looking forward to.

Therefore, in order to achieve the above-mentioned purpose, an embodiment of the present disclosure is related to a mobile green energy water purification device, comprising: a power supply device, which provides green energy electricity; a mobile hollow container, the container comprising a space to accommodate at least: a pumping device, used to extract a raw water; a precipitator, which is configured to receive the raw water extracted by the pumping device and separate and discharge a particulate wastewater in the raw water to form a decontaminated water; a sand filter, which is fluidly connected to the precipitator to receive the decontaminated water from the precipitator and filter the decontaminated water to form a clean water; a water storage A device, which is fluidly connected to the sand filter to receive and store the clean water; a disinfection device, which is located in the water storage device, to add a disinfectant to the clean water to eliminate bacteria and viruses in the clean water to form drinking water; and a monitoring system, which monitors and controls the operation of the power supply device, the pumping device, the precipitator, the sand filter, the water storage device and the disinfection device in real time, wherein the power supply device is at least partially arranged outside the container and is electrically connected to the monitoring system, the pumping device, the precipitator, the sand filter, the water storage device and the disinfection device.

Another embodiment of the present disclosure is a water purification method for providing drinking water to a village or settlement population, which includes: providing a movable green energy water purification device, moving the water purification device to a water intake area for installation, the water purification device includes a hollow container and a power supply device disposed outside the container, the container includes a space for accommodating at least a pumping device, a precipitator, a sand filter, a water storage device, a disinfection device and a monitoring system, all of which are electrically connected to the power supply device; using the power supply device to generate electricity to drive the pumping device to extract raw water; receiving and treating the raw water through the precipitator, Separate and discharge a particle-containing wastewater in the raw water to form a decontaminated water; the sand filter is in fluid communication with the precipitator to filter the decontaminated water through the sand filter to form clean water; the water storage device is in fluid communication with the sand filter to receive and store the clean water through the water storage device; the disinfection device is located in the water storage device to add a disinfectant to the clean water through the disinfection device to eliminate bacteria and viruses in the clean water to form drinking water; and the monitoring system is used to monitor and control the operation status of the power supply device, the pumping device, the precipitator, the sand filter, the water storage device and the disinfection device in real time.

In order to better understand the features, contents and advantages of this disclosure and the effects it can achieve, this disclosure is described in detail as follows with accompanying drawings and in the form of embodiments. The drawings used therein are only for illustration and auxiliary description. Therefore, the proportions and configurations of the attached drawings should not be interpreted to limit the scope of the patent application of this creation.

Please refer to Figures 1 and 2. Figure 1 is a schematic diagram of the water purification device 1 disclosed herein. The water purification device 1 includes a hollow container 10 and a power supply device 17. The container 10 is movable and transportable. In one embodiment of the present disclosure, the container 10 is a 20-foot container, which can be conveniently moved to the required site by a trailer or a tractor. After confirming that water can be obtained in the water intake area (for example: rivers, lakes, springs or appropriately deep wells drilled), the container 10 is moved to the water intake area or its surrounding area for installation, so that the water purification device 1 can perform water purification treatment to provide clean drinking water for the population of villages or settlements, improve drinking water hygiene and maintain the health needs of residents. The container 10 includes an internal space to accommodate a pumping device 11, a precipitator 12, a sand filter 13 (also called a filter), a disinfection device 14, a monitoring system 15, and a water storage device 16. The power supply device 17 is at least partially disposed outside the container 10 and is electrically connected to the pumping device 11, the precipitator 12, the sand filter 13, the disinfection device 14, the monitoring system 15, and the water storage device 16.

FIG. 2 is another schematic diagram of the water purification device 1 disclosed herein, wherein the container 10 and the solar photovoltaic panel are not shown. As shown in FIG. 2 , the pumping device 11 extracts groundwater or surface water as raw water to be filtered and purified. In one embodiment of the present disclosure, the pumping device 11 can extract about 10 to 20 tons of raw water per day, and transport the extracted raw water to be filtered and purified to the precipitator 12 via the water pipe 111.

Please refer to FIG3. FIG3 is a schematic cross-sectional view of the precipitator 12 of the present disclosure. The precipitator 12 includes a precipitator unit 121, a particle receiver 122, and a housing 123. The housing 123 is provided with a water collecting pipe 1231, which is located at a high position of the side wall 1232 of the housing 123, and is used to collect and discharge water (hereinafter referred to as "decontaminated water") treated by the precipitator 12. In another embodiment of the present disclosure, the water collecting pipe 1231 can be respectively set at different height positions of the side wall 1232 of the housing 123 according to the requirements of water quality collection, for example: set at a high position, a middle position, and a low position (not shown) of the side wall 1232 of the housing 123 to collect water at different heights. Due to the internal structural configuration of the precipitator 12, the higher the position of the water collecting pipe 1231 is set on the outer shell 123, the better the water quality will be. Therefore, at the high position of the side wall 1232 of the outer shell 123, cleaner water quality can be collected, while at the middle and low positions of the side wall of the outer shell 123, the water quality collected will be poorer. Therefore, depending on the local water quality conditions, the water collecting pipe 1231 can be set at different heights of the side wall 1232 to facilitate subsequent water purification treatment.

The sedimentation unit 121 is disposed in the outer shell 123. In one embodiment of the present disclosure, a plurality of sedimentation units 121 are disposed in the outer shell 123 (in the embodiment shown in FIG. 2 and FIG. 3 , each outer shell 123 has 16 sedimentation units 121). The number of sedimentation units 121 disposed can be determined according to the water quality and water supply of the local water source. The sedimentation unit 121 is in the shape of a conical tube with a larger upper portion and a smaller lower portion. The upper end of the sedimentation unit 121 is a water inlet 1211 with a larger diameter. In one embodiment of the present disclosure, the diameter of the water inlet 1211 is about 10 cm. The lower end of the sedimentation unit 121 is a water outlet 1212 with a smaller diameter. In one embodiment of the present disclosure, the diameter of the water outlet 1212 is about 5 cm. Between the water inlet 1211 and the water outlet 1212 is the water flow acceleration section 1213. The water flow acceleration section 1213 has a diameter gradient section. The diameter of the diameter gradient section gradually decreases from the water inlet diameter to the water outlet diameter. Since the water flow speed increases as the pipe diameter decreases, when the water flows through the diameter gradient section of the water flow acceleration section 1213, the water flow speed increases accordingly, thereby increasing the vertical downward inertial sedimentation speed of the particles P in the water, achieving the effect of separating the particles P in the water, that is, separating the particle-containing pollutants in the raw water to form a decontaminated water W. The decontaminated water W flows out of the sedimentation unit 121 through the water collection pipe 1231.

The particle collector 122 is arranged below the sedimentation unit 121. The number and position of the particle collector 122 correspond to the sedimentation unit 121. The particle collector 122 has an opening 1221 aligned with the water outlet 1212 of the sedimentation unit 121, which is used to receive the particles P in the water flowing vertically downward from the water outlet 1212 of the sedimentation unit 121, and further collect the wastewater containing particles. The diameter of the opening 1221 of the particle collector 122 is larger than the diameter of the water outlet 1212 of the sedimentation unit 121, so as to facilitate receiving the particles P in the water flowing vertically downward from the water outlet 1212 of the sedimentation unit 121. The particle collector 122 is provided with a control valve 1222, which can control the flow rate of the wastewater containing particles discharged from the particle collector 122 and further concentrate it. The wastewater containing particles then flows downward to the temporary storage tank 125.

The dirty water receiver 124 is located below the temporary storage tank 125 of the sedimentation unit 121, and is used to collect the particulate wastewater discharged from the temporary storage tank 125 through the pipe 126. The dirty water receiver 124 is conical in shape and has a control valve 1241 at its bottom. In addition to concentrating the received particulate wastewater to form high-turbidity wastewater, it can also control the flow rate of the discharged high-turbidity wastewater. The discharged high-turbidity wastewater can be used for non-drinking purposes, such as soil irrigation, environmental cleaning, etc., which helps to save water resources.

Please refer to Figures 4A and 4B. Figure 4A is a top view of the sand filter 13 of the present disclosure. Figure 4B is a cross-sectional schematic diagram of the sand filter 13 and the water storage device 16 of the present disclosure. The sand filter 13 includes a filter fine sand layer 131, a sand scraping device 132, a housing 133 and a collector 134. The housing 133 has a receiving pipe 1331 connected to the water collecting pipe 1231 of the precipitator 12, and receives the dewaxed water W overflowing from the precipitator 12, as shown in Figure 2. In another embodiment of the present disclosure, when the water collecting pipe 1231 has multiple water collecting pipes 1231 at different heights, the multiple water collecting pipes 1231 can be firstly integrated into a single pipeline and then connected to the receiving pipe 1331. By opening and closing the water collecting pipes 1231, the water quality of the wastewater W flowing into the sand filter 13 can be controlled. The sand filters 13 have interconnected pipelines 135. The filter fine sand layer 131 is disposed in the outer shell 133 of the sand filter 13. In order to enable the filter fine sand layer 131 to effectively filter the decontaminated water W, the receiving tube 1331 is arranged above the filter fine sand layer 131, so that the decontaminated water W flowing out of the receiving tube 1331 can be filtered by the filter fine sand layer 131 to form clean water. In one embodiment of the present disclosure, the filter fine sand layer 131 is composed of fine sand of a specific size, quantity and mixing ratio, and is laid in a specific thickness in the sand filter 13 to serve as a base material for filtering the decontaminated water W.

The scraping device 132 is disposed in the sand filter 13. The scraping device 132 has a strip-shaped scraping rod 1322 driven by a driving motor (not shown) to rotate around a central axis. The scraping rod 1322 contacts the filter fine sand layer 131 to scrape off the biofilm deposited on the filter fine sand layer 131 by the sewage. After the filter fine sand layer 131 filters the sewage for a period of time, the sewage will gradually deposit biofilm on the surface of the filter fine sand layer 131, thereby reducing the filtration rate of the filter fine sand layer 131. In order to improve the filtering rate of the fine sand layer 131, the scraper bar 1322 can be rotated to scrape away the biofilm formed on the fine sand surface of the fine sand layer 131, and maintain the rate at which the fine sand layer 131 filters the sewage to form clean water. The bottom of the sand filter 13 has a collector 134 for receiving the clean water after filtering by the fine sand layer 131. The collector 134 is conical in shape, so that the collected clean water will flow to the lowest conveying pipe 1341 and flow into the water storage device 16.

The water storage device 16 is located below the sand filter 13. A water inlet 161 is provided at the top of the water storage device 16 to receive clean water input from the delivery pipe 1341 of the collector 134. The water storage devices 16 have interconnected pipelines 163. The number of water storage devices 16 can be configured according to demand. The disinfection device 14 is arranged in the water storage device 16. The disinfection device 14 has an injection pump 141 for adding disinfectant. In one embodiment, the disinfection device is a chlorinator, and the disinfectant is a chlorine-containing compound (for example, a diluted sodium hypochlorite solution) to remove trace bacteria and viruses in the clean water to make safe and hygienic chlorinated drinking water. The drinking water can be output and taken from the water intake 162 of the water storage device 16. To control and monitor the quality of drinking water in the water storage device 16, the monitoring system 15 regulates the chlorinator by breakpoint chlorination. When the monitoring system 15 detects that the water quality in the water storage device 16 is lower than the preset value, the injection pump 141 will automatically add chlorine compounds. Since water quality is closely related to the conditions of local rainfall, soil, pollution and groundwater, the monitoring system 15 will also regularly test the relationship between the amount of chlorine added and the amount of residual chlorine in the drinking water to ensure the quality of drinking water. In addition, in one embodiment of the present disclosure, if the power supply permits and the water quality requirements are met, the chlorinated drinking water can be further treated by RO reverse osmosis to further improve the quality of drinking water.

The power supply device 17 generates electricity in a green energy manner. In one embodiment of the present disclosure, as shown in FIG. 1 , the power supply device 17 uses solar power generation, where a plurality of solar photovoltaic panels 172 absorb sunlight to generate electricity, and the electricity is stored in an energy storage device 171. The solar photovoltaic panels 172 are disposed on the top of the container 10, and their angles can be adjusted so that the solar photovoltaic panels 172 face the position of the sun. The installation area of the solar photovoltaic panels 172 can be adjusted according to the local sunshine conditions and power generation requirements. In one embodiment, the energy storage device 171 is housed in the container 10. In order to improve the power generation efficiency, the monitoring system 15 will automatically adjust the angle of the solar photovoltaic panel 172 according to the sunshine position, so that the surface of the solar photovoltaic panel 172 faces the position of the sunshine sun. In another embodiment of the present disclosure, the power supply device 17 can also use wind power generation or use wind power generation in parallel, by setting a plurality of blades (for example: rotating blades or spiral blades) (not shown) to generate electricity. When the blade is a rotating blade, the monitoring system 15 can automatically adjust the angle of the rotating blade according to the windward angle to improve the power generation efficiency. When the blade is a spiral blade, it can be fixed to adapt to different wind directions. When the location or climate conditions of the water intake area cannot generate sufficient electricity in a green energy manner, a backup diesel generator (not shown) can be installed in the container 10 to provide emergency power generation to supply the water purification device 1.

The power supply device 17 supplies the power required by the water purification device 1 of the present disclosure. For example, in one embodiment, the power supply device 17 is electrically connected to the pumping device 11, the control valve 1222 of the particle collector 122, the control valve 1241 of the dirty water receiver 124, the sand scraping device 132, the disinfection device 14, the monitoring system 15 and the water storage device 16. However, in the case of insufficient power, some equipment such as the pumping device 11, the control valve 1222 of the particle collector 122, the control valve 1241 of the dirty water receiver 124, the sand scraping device 132 and the disinfection device 14 can also be changed to manual operation.

The monitoring system 15 has computer equipment and wireless network communication equipment, and has water quality monitoring instruments such as pH meter, residual chlorine meter, turbidity meter, conductivity meter, and a sensing device for monitoring the operation of the water purification device 1. In addition to real-time measurement of water quality, it can also monitor the operation of the power supply device 17, pumping device 11, sedimentation device 12, sand filter 13, water storage device 16 and disinfection device 14. After the data and information are analyzed and processed by the computer equipment, they are transmitted to the equipment monitor in real time through the wireless network communication equipment. The equipment monitor can also remotely control or train local people to operate the water purification device 1 on site, achieving the function of real-time and remote control, reducing the cost of manpower maintenance.

For example, in one embodiment, the monitoring system 15 monitors and controls the control valve 1222 of the particle collector 122, the control valve 1241 of the dirty water receiver 124, the injection pump and the scraping device 132 of the disinfection device 14, etc.

Please refer to Figures 1 to 4B. The water purification method using the water purification device 1 includes the following steps:

Step (a), as shown in FIG1 , provides a water purification device 1, and moves the water purification device 1 to a water intake area for installation. The water purification device 1 includes a container 10 and a power supply device 17. The container 10 is a 20-foot container, in which the equipment can be loaded by a trailer or a tractor, so as to facilitate transportation to the water intake area for installation. Before installation, first find a water source or drill a well in the predetermined water intake area, and then set up at an appropriate location nearby. The container 10 includes a pumping device 11, a precipitator 12, a sand filter 13, a disinfection device 14, a monitoring system 15 and a water storage device 16. The power supply device 17 is at least partially disposed outside the container 10 and is electrically connected to the pumping device 11, the precipitator 12, the sand filter 13, the disinfection device 14, the monitoring system 15 and the water storage device 16.

Step (b), as shown in FIG1 , the power supply device 17 generates electricity in a green energy manner (e.g., solar power generation) to supply the water purification device 1 with the required electricity for operation. In order to effectively improve the power generation efficiency, the solar photovoltaic panel 172 of the power supply device 17 is movable, and the monitoring system 15 automatically adjusts the angle of the solar photovoltaic panel 172 according to the sunshine position, so that the surface of the solar photovoltaic panel 172 faces the position of the sunshine sun. In another embodiment of the present disclosure, the power supply device 17 can also generate electricity using wind power (not shown). In addition, when the location or climate of the water intake area cannot generate enough electricity in a green energy manner, a backup diesel generator (not shown) can be installed in the container 10 to provide emergency power supply or supplementary power for the operation of the water purification device 1. In this way, the pumping device 11 extracts groundwater or surface water (raw water to be filtered and purified) and transports it to the precipitator 12 through the water pipe 111. The pumping device 11 can extract at least about 20 tons of groundwater or surface water per day as raw water to be filtered and purified, which can provide more than 1,000 people in the village or settlement daily, reaching the standard of 20 liters of safe and hygienic drinking water per person per day. If the number of people in need increases, the scale of the water purification device 1 can be expanded or increased to achieve the water supply target.

Step (c), as shown in FIG3 , after the filtered and purified raw water passes through the precipitator 12 for treatment, the particulate wastewater in the raw water is separated and discharged to form de-wastewater W. First, the filtered and purified raw water enters the water inlet 1211 of a plurality of precipitators 121 from the upper end of the precipitator 12. The pipe diameter of the precipitator 121 is roughly maintained consistent between the water inlet 1211 and before entering the water flow acceleration section 1213, so that the raw water flows evenly when passing through, and the particles P in the raw water are linearly precipitated in a stable and directional manner. When the raw water passes through the water flow acceleration section 1213, since the pipe diameter at the inlet of the water flow acceleration section 1213 is larger than the pipe diameter at the outlet, the pipe diameter gradually decreases from large to small, causing the raw water to gradually accelerate when passing through the water flow acceleration section 1213, and the particles P in the raw water are also accelerated, increasing the vertical downward inertial sedimentation velocity. The pipe diameter is roughly the same from the water flow acceleration section 1213 to the water outlet 1212, so that the raw water flows steadily and is less disturbed when passing through. The particles P in the water maintain a stable and rapid downward sedimentation. The particles P in the water enter the particle collector 122 located directly below vertically downward according to their inertial direction. The wastewater W that has removed the particles P in the water will move outward above the particle collector 122 and flow to the water collection pipe 1231 on the side wall 1232 of the outer shell 123 and be discharged to the sand filter 13. The control valve 1222 provided in the particle collector 122 controls the flow rate of the wastewater containing particles discharged from the particle collector 122, and further concentrates it, and then discharges it to the temporary storage tank 125 below. The particle-containing wastewater in the temporary storage tank 125 will be discharged to the dirty water receiver 124 below through the conduit 126. The dirty water receiver 124 is conical in shape, so that the particle-containing wastewater flows to the bottom of the dirty water receiver 124, and is concentrated by the control valve 1241 installed at the bottom of the dirty water receiver 124 to form high-turbidity wastewater, and the flow rate of the discharged high-turbidity wastewater is controlled. The discharged high-turbidity wastewater will be used for non-drinking purposes, such as soil irrigation, environmental cleaning, etc., to achieve the purpose of effective utilization of water resources in water-scarce or disaster-stricken areas, and save water resource waste.

Step (d), as shown in Figures 4A and 4B, the sand filter 13 filters the decontaminated water W overflowing from the precipitator 12 to form clean water. The decontaminated water W from the precipitator 12 overflows through the water collecting pipe 1231 and the receiving pipe 1331 of the sand filter 13, and is filtered through the fine sand layers in the filter fine sand layer 131 below to form clean water. The filtered clean water is collected in the collector 134 below the sand filter 13. The conical collector 134 allows the clean water to flow to the bottom and be input into the water storage device 16 below through the conveying pipe 1341. When the monitoring system 15 detects that the rate of the sand filter 13 filtering the wastewater W is lower than the preset value, the sand scraping device 132 is driven to operate, and the driving motor of the sand scraping device 132 drives the sand scraping rod 1322 to scrape the biofilm formed on the surface of the fine sand in the filter fine sand layer 131 in a rotating manner. When the monitoring system 15 detects that the rate of the sand filter 13 filtering the wastewater W returns to the preset value, the sand scraping device 132 is stopped.

Step (e), as shown in FIG. 4B , the disinfection device 14 adds a disinfectant such as a chlorine compound to the clean water to eliminate bacteria and viruses in the clean water to form drinking water, and stores it in the water storage device 16, and can be output from the water intake 162 of the water storage device 16 for use. The monitoring system 15 controls the injection pump 141 of the disinfection device 14 to add a chlorine compound (e.g., a sodium hypochlorite dilute solution) to the stored water in the water storage device 16 to remove trace bacteria and viruses in the water. The monitoring system 15 regulates the disinfection device 14 in a breakpoint chlorination mode. When the monitoring system 15 detects that the water quality in the water storage device 16 is lower than a preset value, the injection pump 141 will automatically add a chlorine compound. Monitoring equipment 15 will also regularly test the relationship between the amount of chlorine added and the residual chlorine in the water to ensure that the optimal chlorination conditions are achieved and the water quality is maintained stable.

Step (f), the monitoring system 15 monitors the operating status of the water purification device 1 in real time. The monitoring system 15 monitors the data monitored by water quality monitoring instruments such as pH meters, residual chlorine meters, turbidity meters, and conductivity meters, and monitors the sensing devices installed on the water purification device 1. After being processed by computer equipment, the data and information are transmitted to the equipment monitor in real time through wireless network communication equipment. The equipment monitor can understand the operating status of the water purification device 1 in real time. The equipment monitor can also remotely control or train local personnel to operate and adjust parameters and settings on site.

The present invention is a highly efficient water purification device, which is mainly used in areas with water shortages such as earthquake disaster areas, floods and other areas, or remote areas in Africa where water is scarce. After obtaining water from rivers, lakes, springs or drilling wells of appropriate depth, the water purification device of the present invention can be used in nearby areas to directly provide safe and sanitary drinking water to residents in the surrounding areas, thereby improving the sanitation and health needs of drinking water. The water purification device of the present invention is installed in a movable container (e.g., a container) and is moved to a place with a water source and a stable foundation by a conventional trailer or tractor. Raw water is extracted from the water source by its own green power system (solar or wind power generation). After the water is purified by the water purification device of the present invention, safe and hygienic drinking water is directly produced to provide nearby residents with short-term emergency, medium-term maintenance or long-term water supply. The features of the water purification device of the present invention are: (1) After obtaining a stable water source, safe and hygienic drinking water can be produced on site immediately; (2) No chemical coagulant is required for pre-treatment of high turbidity water; (3) A sand filter that automatically scrapes off surface biofilm; (4) Green power from sunlight or wind makes the present invention applicable to remote places without power supply; (5) No chemical coagulant or waste is generated, and it can operate stably for a long time; (6) The computer network system can be used to remotely monitor and operate the device, and only one or two on-site maintenance is required each year. The use of the water purification device of the present invention can avoid the conventional water purification plant which requires a large area of land, uses chemicals, generates a large amount of chemical sludge and requires manpower for on-site operation. There will also be no problems such as the frequency of backwashing sand and a large amount of backwashing water.
