Description

Movable green energy water purifying device and water purifying method thereof

Technical Field

The invention relates to a movable green energy water purifying device and a water purifying method thereof.

Background

In remote or high altitude areas, the traditional drinking water of residents mostly uses well water or mountain spring water directly without any water purifying and sterilizing treatment. However, when wind disaster or other natural disasters occur, the raw water is in poor condition or the water supply is insufficient, so that the water shortage problem is caused. In addition, in some later remote areas, people often drink untreated raw water directly, and serious gastrointestinal diseases can be caused for a long time, the health can be influenced, and even the life can be endangered. Therefore, the long-term stable obtaining of safe and hygienic drinking water is an important basis for improving quality of life and maintaining health.

The current water purification method is to perform coagulating sedimentation pretreatment by chemical agents, and the water purification method can provide a large amount of drinking water in a small area, but generates a large amount of chemical sludge. Moreover, how to dispose of and dispose of this chemical sludge in an environmentally friendly manner is a further troublesome problem.

In addition, in some later remote areas, a sound power system is not available, so that stable and sufficient power required by water purifying devices with larger power requirements (such as reverse osmosis and ion exchange) cannot be supplied, and due to the remote places, technicians are difficult to handle the water purifying devices on site frequently, so that the water purifying devices are difficult to perform normal functions, and ordinary maintenance is difficult to perform.

In view of this, a water purifying device and a water purifying method thereof have been developed which can be moved to disaster areas, remote locations, high altitudes or later areas conveniently, and after water is obtained, safe and sanitary drinking water can be produced immediately, pretreatment of coagulating sedimentation is not performed by using chemical agents in the water purifying process, no chemical sludge is generated, the water purifying device is driven by green energy electricity without being affected by insufficient local electricity supply and the like, and the water purifying device has an automatic operation function of remote monitoring, so that the water purifying device is really a long-felt enterprise for people in these areas.

Detailed Description

For a better understanding of the features, aspects and advantages of the present invention, as well as the advantages and capabilities thereof, reference should be made to the following detailed description of the present invention in conjunction with the accompanying drawings and given by way of example only, and the accompanying drawings used herein are merely schematic and serve to illustrate the present invention and not to limit the scope of the invention in any way in relation to the scale and arrangement of the accompanying drawings.

Please refer to fig. 1 and 2. Fig. 1 is a schematic view of a water purifying apparatus 1 according to the present invention. The water purifying device 1 comprises a hollow container 10 and a power supply device 17. The container 10 is portable and in one embodiment of the invention, the container 10 is a 20 feet container that can be conveniently moved to a desired location with a trailer or truck. After confirming that a water source can be obtained in a water intake area (such as a river, a lake, spring water or drilling a proper deep well), the container 10 is moved to the water intake area or the vicinity thereof for installation, so that the water purifying device 1 can perform water purification treatment to provide clean drinking water for village or landing population, promote drinking water sanitation and maintain health requirements of residents. The container 10 includes an interior space to house a water pump 11, a sediment vessel 12, a sand filter 13 (also known as a filter), a sterilizing device 14, a monitoring system 15, and a water storage device 16. The power supply device 17 is at least partially arranged outside the container 10 and is electrically connected with the pumping device 11, the precipitator 12, the sand filter 13, the sterilizing device 14, the monitoring system 15 and the water storage device 16.

Fig. 2 is another schematic view of the water purifying device 1 of the present invention, wherein the container 10 and the solar photovoltaic panel are not shown. As shown in fig. 2, the water pumping device 11 pumps groundwater or surface water as raw water to be filtered and purified. In one embodiment of the present invention, the pumping device 11 may pump about 10 to 20 metric tons of raw water per day, and convey the pumped raw water to be filtered and purified to the precipitator 12 through the water pipe 111.

Please refer to fig. 3. Fig. 3 is a schematic cross-sectional view of the settler 12 of the invention. The precipitator 12 includes a precipitation unit 121, a particle receiver 122 and a housing 123. The housing 123 is provided with a water collecting pipe 1231 located at a high position of a side wall 1232 of the housing 123 for collecting and discharging water treated by the settler 12 (hereinafter referred to as "decontaminated water"). In another embodiment of the present invention, water collection pipes 1231 may be disposed at different heights on the side wall 1232 of the housing 123 according to the water quality collection requirements, for example: high, medium, and low (not shown) in the sidewall 1232 of the housing 123 to collect water at different heights. Due to the structural configuration of the inside of the settler 12, the quality of the water collected by the water collecting pipe 1231 disposed at the higher position of the outer shell 123 will be better. Accordingly, at the high position of the side wall 1232 of the outer case 123, clean water quality is collected, and at the middle and low positions of the side wall of the outer case 123, the collected water quality is poor. Accordingly, the water collection pipe 1231 is selectively disposed at different height positions of the sidewall 1232 depending on the local water quality condition, so that the subsequent water purification treatment can be facilitated.

The precipitation unit 121 is disposed in the housing 123. In one embodiment of the present invention, a plurality of precipitation units 121 are provided in the housing 123 (16 precipitation units 121 are provided in each housing 123 in the embodiment shown in fig. 2 and 3). The number of the settling units 121 may be set according to the water quality of the local water source and the water supply amount. The sedimentation unit 121 is in the shape of a conical tube with a large upper part and a small lower part, and the upper end of the sedimentation unit 121 is provided with a water inlet 1211 with a larger diameter, and in one embodiment of the invention, the diameter of the water inlet 1211 is about 10 cm. The lower end of the sedimentation unit 121 is a water outlet 1212 having a smaller diameter, and in one embodiment of the present invention, the water outlet 1212 has a diameter of about 5 cm. Between the water inlet 1211 and the water outlet 1212 is a water flow accelerating section 1213, the water flow accelerating section 1213 has a diameter-reducing section, the diameter of the diameter-reducing section is reduced from the diameter of the water inlet to the diameter of the water outlet, and the water flow speed is increased along with the diameter reduction of the water flow, so that when the water flow passes through the diameter-reducing section of the water flow accelerating section 1213, the water flow speed is increased, thereby increasing the vertically downward inertial sedimentation speed of the particles P in the water, and achieving the effect of separating the particles P in the water, namely separating the sewage containing the particles in the raw water, to form a sewage-removing water W, and the sewage-removing water W flows out of the sedimentation unit 121 through the water collecting pipe 1231.

The particle collector 122 is disposed below the precipitation unit 121. The number and positions of the particle collectors 122 are set corresponding to the precipitation unit 121. The particle collector 122 has an opening 1221 aligned with the water outlet 1212 of the sedimentation unit 121 for receiving the particles P in the water flowing vertically downward from the water outlet 1212 of the sedimentation unit 121, thereby collecting the sewage 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 precipitation unit 121 to facilitate receiving the particles P in the water flowing vertically downward from the water outlet 1212 of the precipitation unit 121. The particle trap 122 is provided with a control valve 1222 that controls the flow of the particle-containing sewage discharged by the particle trap 122 and may further concentrate it. The particle-containing sewage then merges downward into a temporary storage tank 125.

The turbid water receiver 124 is located below the temporary storage tank 125 of the settling unit 121, and is used for converging the fine particle-containing sewage discharged from the temporary storage tank 125 through the conduit 126. The turbid water receiver 124 has a tapered shape and a control valve 1241 at the bottom end thereof, and can control the flow rate of discharged high-turbidity sewage in addition to concentrating the received fine-particle-containing sewage to form high-turbidity sewage. The discharged high turbidity sewage can be used for non-drinking water applications, such as: soil irrigation, environmental cleaning, etc., and is helpful for saving water resources.

Please refer to fig. 4A and 4B. Fig. 4A is a top view of the sand filter 13 of the present invention. Fig. 4B is a schematic cross-sectional view of the sand filter 13 and the water storage device 16 according to the present invention. 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 water collection pipe 1231 communicating with the settler 12 through a receiving pipe 1331, receiving the decontaminated water W overflowed from the settler 12, as shown in fig. 2. In another embodiment of the present invention, when the water collecting pipe 1231 has a plurality of water collecting pipes 1231 of different height positions, the plurality of water collecting pipes 1231 may be collected into a single line and then connected to the receiving pipe 1331, and the quality of the sewage W flowing into the sand filter 13 may be controlled by opening and closing the water collecting pipes 1231. The sand filter 13 has a line 135 communicating with each other. The filter fine sand layer 131 is disposed in the housing 133 of the sand filter 13. In order to effectively filter the decontaminated water W by the fine sand filter layer 131, the receiving tube 1331 is disposed above the fine sand filter layer 131, so that the decontaminated water W flowing out of the receiving tube 1331 can be filtered by the fine sand filter layer 131 to form clean water. In one embodiment of the present invention, the filtering fine sand layer 131 is composed of fine sand of a specific size, amount and mixing ratio, and a specific thickness is laid in the sand filter 13 as a substrate for filtering the sewage W.

The sand scraping device 132 is provided in the sand filter 13. The scraping device 132 has a scraping rod 1322 which is in a long strip shape driven by a driving motor (not shown) to rotate around a central axis. The scraping rod 1322 contacts the filtering fine sand layer 131, thereby scraping off the biofilm deposited on the filtering fine sand layer 131 by the sewage W. After filtering the filtered fine sand layer 131 to remove the sewage W for a while, the decontaminated water gradually deposits a biofilm on the surface of the filtered fine sand layer 131, thereby reducing the filtering rate of the filtered fine sand layer 131. To increase the filtration rate of the fine sand layer 131, the biological film generated on the fine sand surface of the fine sand layer 131 by the sewage W is scraped off by rotating the scraping rod 1322, so as to maintain the filtration rate of the fine sand layer 131 for filtering the decontaminated water W to form clean water. The bottom of the sand filter 13 has a collector 134 for receiving the clear water filtered through the fine sand layer 131. The collector 134 is tapered so that the collected fresh water flows down the lowermost duct 1341 into the water reservoir 16.

The water storage device 16 is positioned below the sand filter 13, and a water inlet 161 is formed at the top of the water storage device 16 to receive the clean water fed from a conveying pipe 1341 of the collector 134, and a pipeline 163 is formed between the water storage devices 16. The number of water storage devices 16 can be configured as desired. The sterilizing device 14 is disposed in the water storage device 16, and the sterilizing device 14 has a syringe pump 141 for adding a sterilizing substance. In one embodiment, the disinfection device is a chlorinator, the disinfection material is a chlorine-containing compound (e.g. diluted sodium hypochlorite solution) for removing trace bacteria and viruses in the clean water, and the disinfection device becomes safe and sanitary chlorine-containing drinking water, which can be output and taken out from the water intake 162 of the water storage device 16. To control and monitor the quality of the potable water in the water storage device 16, the monitoring system 15 regulates and controls the chlorinator in a breakpoint chlorinating (breakpoint chlorination) manner. When the monitoring system 15 monitors that the water quality condition in the water storage device 16 is lower than the default value, the syringe pump 141 automatically adds chlorine-containing compounds. Because the water quality is closely related to the local rainfall, soil quality, pollution and the condition of the water intake source such as groundwater, the monitoring system 15 also can periodically test the relationship between the chlorine adding amount and the residual chlorine amount in the drinking water to ensure the quality of the drinking water. In addition, in one embodiment of the invention, if the electric power supply is permitted and the water quality is required, the chlorine-containing drinking water can be further treated by RO reverse osmosis, so that the drinking water quality is further improved.

The power supply device 17 generates power in a green energy manner. In an embodiment of the present invention, as shown in fig. 1, the power supply device 17 uses solar energy to generate electricity, and the plurality of solar photovoltaic panels 172 absorb sunlight to generate electricity, and store the electricity in the energy storage device 171. The solar photovoltaic panel 172 is disposed on the top of the container 10, and the angle thereof can be adjusted so that the solar photovoltaic panel 172 faces the sun-shining position. The installation area of the solar photovoltaic panel 172 can be adjusted according to local sunlight 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 automatically adjusts the angle of the solar photovoltaic panel 172 according to the sunlight position, so that the surface of the solar photovoltaic panel 172 faces the sunlight position. In another embodiment of the present invention, the power supply device 17 may use wind power instead of or in parallel to generate electricity by providing a plurality of blades (e.g. rotating blades or helical blades) (not shown). When the blades are rotating blades, the monitoring system 15 can automatically adjust the angles of the rotating blades according to the windward angle, so that the power generation efficiency is improved. When the blades are helical blades, a fixing mode can be adopted to adapt to different wind directions. When the water intake area is located or the climate condition cannot generate enough power in a green energy mode, a standby diesel power generation device (not shown) can be additionally arranged in the container 10 for emergency power generation to supply the operation of the water purification device 1.

The power supply device 17 supplies power required for the water purifying device 1 of the present invention. For example, in one embodiment, the power supply 17 is electrically connected to the water pump 11, the control valve 1222 of the particulate trap 122, the control valve 1241 of the turbid water receiver 124, the sand scraping device 132, the disinfection device 14, the monitoring system 15, the water storage device 16, and the like. However, in the event of insufficient power, some of the devices, such as the pump 11, the control valve 1222 of the particle collector 122, the control valve 1241 of the turbid water receiver 124, the scraping device 132, the disinfection device 14, etc., may be manually operated instead.

The monitoring system 15 has computer equipment and wireless network communication equipment, has water quality monitoring instruments such as pH value meter, residual chlorine meter, turbidity meter, conductivity meter and the like, and has a sensing device for monitoring the operation of the water purifying device 1, besides measuring the water quality in real time, the monitoring system can also monitor the operation conditions of the power supply device 17, the water pumping device 11, the precipitator 12, the sand filter 13, the water storage device 16 and the disinfection device 14, analyze and process the data and the data through the computer equipment, and then transmit the data to an equipment monitor in real time through the wireless network communication equipment, and the equipment monitor can also remotely control or train local people to operate the water purifying device 1 on site, thereby achieving the functions of real-time and remote control and reducing the cost of manpower maintenance.

For example, in one embodiment, the monitoring system 15 monitors and controls the control valve 1222 of the particulate trap 122, the control valve 1241 of the turbid water receiver 124, the syringe pump and the scraping apparatus 132 of the disinfection device 14, and the like.

Please refer to fig. 1 to fig. 4B. The water purifying method using the water purifying apparatus 1 includes the steps of:

Step (a), as shown in fig. 1, a water purifying device 1 is provided, and the water purifying device 1 is moved to a water taking area for installation. The water purifying device 1 includes a container 10 and a power supply device 17. The container 10 is 20 feet container and may be a trailer or truck loading apparatus therein for convenient transport to a water intake area for installation. Before installation, water sources are found in a preset water taking area or water wells are drilled, and then erection is carried out at proper places nearby. The container 10 includes a water pump 11, a sediment vessel 12, a sand filter 13, a sterilizing device 14, a monitoring system 15, and a water storage device 16. The power supply device 17 is at least partially arranged outside the container 10 and is electrically connected with the pumping device 11, the precipitator 12, the sand filter 13, the sterilizing device 14, the monitoring system 15 and the water storage device 16.

In step (b), as shown in FIG. 1, the power supply device 17 generates power in a green energy manner (e.g. solar power generation) to supply the power required by the operation of the water purifying device 1. 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 sunlight position, so that the surface of the solar photovoltaic panel 172 faces the sunlight position. In another embodiment of the present invention, the power supply device 17 may also generate electricity by wind power (not shown). In addition, when the water intake area is located or the climate condition cannot generate enough power in a green energy manner, a spare diesel power generation device (not shown) may be additionally provided in the container 10 to supply or supplement power to the water purifying device 1 for emergency power generation. By this, the water pumping device 11 pumps groundwater or surface water (raw water to be filtered and purified), and sends the groundwater or surface water to the precipitator 12 through the water pipe 111. At least about 20 metric tons of groundwater or surface water can be pumped daily by the water pumping device 11 as raw water to be filtered and purified, and villages or landing population of more than 1000 people can be provided daily, and the standard of 20 liters of safe and sanitary drinking water per person daily can be met. If the number of people in need is increased, the scale of the water purifying device 1 can be enlarged or increased to achieve the water supply target.

Step (c), as shown in fig. 3, after the raw water to be filtered and purified is treated by the precipitator 12, the fine particle-containing sewage in the raw water is separated and discharged to form wastewater W. First, the raw water to be filtered and purified enters the water inlet 1211 of the plurality of precipitation units 121 from the upper end of the precipitator 12, and the pipe diameters of the precipitation units 121 are maintained approximately consistent between the water inlet 1211 and before entering the water flow accelerating section 1213, so that the water flow is uniform when the raw water passes through, and particles P in the raw water stably and linearly settle downwards. When raw water passes through the water flow accelerating section 1213, since the pipe diameter at the inlet of the water flow accelerating section 1213 is larger than the pipe diameter at the outlet, the pipe diameter gradually becomes smaller from large to small, so that the raw water is gradually accelerated when passing through the water flow accelerating section 1213, and particles P in the raw water are also accelerated along with the raw water, so that the vertically downward inertia sedimentation speed is increased. After the water flow accelerating section 1213, the pipe diameter is kept approximately uniform to ensure that the water flow is stable and reduced to be disturbed when the raw water passes through, the particles P in the water are stably and rapidly settled downwards, the particles P in the water vertically downwards enter the particle collector 122 positioned right below according to the inertia direction, the decontaminated water W for removing the particles P in the water moves outside above the particle collector 122, and the water collecting pipe 1231 flowing to the side wall 1232 of the shell 123 is discharged to the sand filter 13. The control valve 1222 provided to the particle collector 122 controls the flow of the particle-containing sewage discharged from the particle collector 122, and further concentrates it, and then discharges it to the temporary storage tank 125 below. The dirty water containing particles in the holding tank 125 is discharged from the turbid water receiver 124 via the conduit 126. The turbid water receiver 124 has a tapered shape, so that the fine particle-containing sewage flows forward to the bottom end of the turbid water receiver 124, is concentrated by a control valve 1241 provided at the bottom end of the turbid water receiver 124 to form high-turbidity sewage, and controls the flow rate of discharged high-turbidity sewage. The discharged high turbidity sewage is used for non-drinking water, for example: soil irrigation, environmental cleaning and the like, achieves the aim of effectively utilizing water resources in water-deficient or disaster areas, and can save water resource waste.

Step (d), as shown in fig. 4A and 4B, the sand filter 13 filters the decontaminated water W overflowed from the precipitator 12 to form clear water. The decontaminated water W from the settler 12 overflows through the receiving pipe 1331 of the sand filter 13 via the water collecting pipe 1231, and forms clean water after filtering the fine sand layer by layer in the fine sand layer 131 by filtering the fine sand layer thereunder. The filtered clean water is collected in a collector 134 below the sand filter 13, and the collector 134 is tapered so that the clean water flows to the bottom and is input into the lower water storage device 16 through a conveying pipe 1341. When the monitoring system 15 detects that the rate of filtering the sewage W by the sand filter 13 is lower than the default 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 biological film generated on the fine sand surface of the filtering fine sand layer 131 in a rotating manner. When the monitoring system 15 detects that the rate of filtering the sewage W by the sand filter 13 is restored to the default value, the operation of the sand scraping device 132 is stopped.

In step (e), as shown in fig. 4B, the disinfection device 14 adds disinfection substances such as chlorine-containing compounds into the clean water, eliminates bacteria and viruses in the clean water to form drinking water, and stores the drinking water in the water storage device 16, and can be output and taken out from the water intake 162 of the water storage device 16. The monitoring system 15 controls the syringe pump 141 of the sterilizing device 14, and adds chlorine-containing compounds (e.g., sodium hypochlorite diluted solution) to the water stored in the water storage device 16 to remove trace bacteria and viruses in the water. The monitoring system 15 controls the sterilizing device 14 by means of break point chlorination breakpoint chlorination. When the monitoring system 15 monitors that the water quality condition in the water storage device 16 is lower than the default value, the syringe pump 141 automatically adds chlorine-containing compounds. The monitoring device 15 also periodically tests the relationship between the chlorine addition amount and the residual chlorine in the water to ensure the optimal chlorine addition condition and maintain the stable water quality.

In step (f), the monitoring system 15 monitors the operation status of the water purifying device 1 in real time. The monitoring system 15 monitors data monitored by water quality monitoring instruments such as a pH meter, a chlorine residual meter, a turbidity meter, a conductivity meter and the like, and monitors a sensing device arranged on the water purifying device 1, and transmits the data and the data to a device monitor in real time through wireless network communication equipment after the data are processed by calculation of computer equipment. The operation condition of the water purifying device 1 can be known by the equipment monitor in real time. The device monitor may also remotely control or train local personnel to adjust parameters and settings for field operations.

The invention relates to a high-efficiency water purifying device, which is mainly used in emergency water shortage areas such as earthquake disaster areas, flood floods and the like or remote areas lacking in africa water sources, and can be used in adjacent areas after water sources are obtained by proper well depths of rivers, lakes, spring water or drilling, so that safe and sanitary drinking water can be directly provided for residents in the adjacent areas, and the sanitary and healthy requirements of the drinking water are improved.
