Description

Technical Field

[0001] This invention belongs to the field of wastewater purification technology, specifically relating to a portable electric pulse wastewater treatment device for use in small bodies of water. Background Technology

[0002] With the development of technology, wastewater treatment has received increasing attention. Currently, common wastewater treatment devices are widely used in urban wastewater treatment, industrial park wastewater treatment, rural domestic sewage treatment, and tourist area wastewater treatment. These devices typically employ advanced biological treatment technologies and physical and chemical treatment methods to remove harmful substances from wastewater, achieving discharge standards or enabling resource utilization.

[0003] Traditional wastewater treatment systems include agitators, filters, and aerators. The agitator stirs the wastewater, the filter filters it, and the aerator forces oxygen into the wastewater, allowing organic matter, microorganisms, and dissolved oxygen to come into full contact. This improves the efficiency of oxidative decomposition of organic matter in the wastewater, enabling the efficient adsorption and degradation of pollutants such as organic matter, nitrogen, and phosphorus, thus purifying the wastewater. However, this structure results in high costs and energy consumption for the agitator, filter, and aerator, leading to high operating costs for traditional wastewater treatment systems.

[0004] On the other hand, most traditional electric pulse sewage treatment equipment uses two large planar plates to release pulse electric fields to achieve water purification. This method greatly reduces the generation of plasma and increases energy consumption. Plasma plays an indispensable role in sewage purification, and reducing plasma means reducing purification efficiency. Summary of the Invention

Detailed Implementation

[0037] The present invention will be further described in detail below with reference to specific embodiments, but the implementation of the present invention is not limited thereto.

[0038] Please see Figure 1 and Figure 2 This invention provides a portable electric pulse sewage treatment device for small water areas, including a housing 1. The housing 1 contains a sewage chamber 2, a purified water chamber 3, and a treatment chamber 4. The sewage chamber 2 is used to store sewage. The treatment chamber 4 contains a first needle-shaped electrode array 5, which includes multiple needle-shaped electrodes arranged in an array. The treatment chamber 4 is equipped with a pulse power supply 6, which is electrically connected to the first needle-shaped electrode array 5. The inlet end of the treatment chamber 4 is connected to the sewage chamber 2, and the outlet end of the treatment chamber 4 is connected to the purified water chamber 3. The sewage in the sewage chamber 2 is purified by the first needle-shaped electrode array 5 in the treatment chamber 4 and then flows into the purified water chamber 3 for storage.

[0039] In some embodiments of this application, the sewage chamber 2 and the clean water chamber 3 are both located at the bottom of the housing 1, and the clean water chamber 3 is located above the sewage chamber 2. The sewage chamber 2 and the clean water chamber 3 are separated by a partition plate.

[0040] In some embodiments of this application, the treatment chamber 4 is arranged vertically, and when sewage flows into the treatment chamber 4, it can pass through the first needle electrode array 5 under the action of gravity and flow into the clean water chamber 3.

[0041] In some embodiments of this application, the needle electrodes in the first needle electrode array 5 are arranged horizontally, and multiple needle electrodes are arranged sequentially in the vertical direction. After the sewage flows into the treatment chamber 4, it can pass through multiple needle electrodes in sequence for electrical pulse degradation, thereby improving the purification efficiency and effect of the sewage treatment device on sewage.

[0042] In some embodiments of this application, the pulse power supply 6 can deliver a high-frequency pulse current to the first needle-shaped electrode array 5. Electrolysis of wastewater using high-frequency pulses can improve the purification efficiency and effectiveness of the treatment chamber 4. Furthermore, the pulse power supply 6 can also deliver electrical pulses of different frequencies to the first needle-shaped electrode array 5. Electrolysis of wastewater using electrical pulses of different frequencies enables the wastewater treatment device to be applicable to water bodies with varying degrees of pollution, thus expanding the applicability of the wastewater treatment device.

[0043] In the above-described scheme of this application, the wastewater treatment device includes a housing 1, which contains a wastewater chamber 2, a purified water chamber 3, and a treatment chamber 4. The wastewater chamber 2 stores wastewater. The treatment chamber 4 contains a first needle-shaped electrode array 5, which includes multiple needle-shaped electrodes arranged in an array. A pulse power supply 6 is installed on the treatment chamber 4 and is electrically connected to the first needle-shaped electrode array 5. The inlet of the treatment chamber 4 is connected to the wastewater chamber 2, and the outlet of the treatment chamber 4 is connected to the purified water chamber 3. The wastewater in the wastewater chamber 2 is purified by the first needle-shaped electrode array 5 in the treatment chamber 4 and then flows into the purified water chamber 3 for storage. Using this structure, a pulse current is supplied to the first needle-shaped electrode array 5 via the pulse power supply 6. The first needle-shaped electrode array 5 performs irreversible electrical pulse degradation on pollutants such as bacteria and organic matter in the wastewater, enabling the wastewater treatment device to effectively purify the wastewater. The multiple needle-shaped electrodes arranged in an array enhance the discharge intensity at the needle tips, improving the wastewater treatment efficiency and purification effect. Furthermore, the wastewater treatment device described in this application has a simple structure, low energy consumption, low cost, and is easy to install and use, resulting in low operating costs. Additionally, the structure described in this application is small in size and easy to carry.

[0044] Furthermore, the portable wastewater treatment device described in this application features a needle-shaped array electrode plate. The needle-shaped discharge method significantly improves plasma generation efficiency while reducing energy consumption. On the other hand, through a novel external water circulation system design, the heat from the pulsed discharge electrode plate promotes the decomposition and volatilization of ozone in the water, greatly improving the quality of the final water source and significantly reducing the cost of secondary treatment.

[0045] In some embodiments of this application, such as Figure 1As shown, the housing 1 is also equipped with a first pipe 7, a second pipe 8, a third pipe 9, a valve 10, and an inlet pump 17. The first pipe 7 is connected to the inlet end of the treatment chamber 4. One end of the second pipe 8 is connected to the sewage chamber 2, and the other end of the second pipe 8 is connected to the first pipe 7. One end of the third pipe 9 is connected to the clean water chamber 3, and the other end of the third pipe 9 is connected to the first pipe 7. The valve 10 is installed on the first pipe 7 and is used to control the connection between the first pipe 7 and the second pipe 8 or the third pipe 9. The inlet pump 17 is installed on the first pipe 7 and is used to pump water from the sewage chamber 2 or the clean water chamber 3 into the treatment chamber 4. With this structure, when the wastewater treatment device is in use, the wastewater in the wastewater chamber 2 can first be pumped into the treatment chamber 4 by the inlet pump 17 for purification. The purified water in the treatment chamber 4 flows to the clean water chamber 3 for storage. Then, the water stored in the clean water chamber 3 after the first purification is pumped into the treatment chamber 4 by the inlet pump 17 for secondary purification. The water after the second purification in the treatment chamber 4 flows to the clean water chamber 3 for storage. This process of pumping water from the clean water chamber 3 into the treatment chamber 4 for repeated purification is repeated to obtain clean water that meets the requirements. In this way, the water in the clean water chamber 3 can be circulated multiple times, thereby improving the purification effect of the wastewater treatment device.

[0046] In some embodiments of this application, valve 10 can be a two-position three-way solenoid valve, with its three ports connected to the first pipeline 7, the second pipeline 8, and the third pipeline 9, respectively, to control one of the second pipeline 8 and the third pipeline 9 to communicate with the first pipeline 7.

[0047] In some embodiments of this application, a first water level sensor 11 is provided in the sewage chamber 2. The first water level sensor 11 is located at the bottom of the sewage chamber 2 and is used to detect whether the sewage water level in the sewage chamber 2 has reached a preset minimum water level. A first controller is also provided in the housing 1. The first water level sensor 11 and the valve 10 are both connected to the controller. The first controller is used to control the first pipeline 7 and the second pipeline 8 to connect through the valve 10 when the first water level sensor 11 does not detect that the sewage water level in the sewage chamber 2 has reached the preset minimum water level. And when the first water level sensor 11 detects that the sewage water level in the sewage chamber 2 has reached the preset minimum water level, it controls the first pipeline 7 and the third pipeline 9 to connect through the valve 10. With this structure, when the first water level sensor 11 does not detect that the sewage level in the sewage chamber 2 has reached the preset minimum water level, the sewage in the sewage chamber 2 still needs to be pumped into the treatment chamber 4 for purification treatment by the inlet pump 17. At this time, the first controller controls the valve 10 to connect the first pipeline 7 and the second pipeline 8, thereby ensuring that the sewage in the sewage chamber 2 can flow into the treatment chamber 4 through the second pipeline 8 and the first pipeline 7. When the first water level sensor 11 detects that the sewage level in the sewage chamber 2 has reached the preset minimum water level, the sewage chamber 2 no longer supplies sewage to the treatment chamber 4. At this time, the first controller controls the valve 10 to connect the first pipeline 7 and the third pipeline 9, so that the water in the clean water chamber 3 can be pumped into the treatment chamber 4 by the inlet pump 17 for multiple circulation purification treatments.

[0048] In some embodiments of this application, the first water level sensor 11 is a device capable of converting the measured water level signal into an electrical signal in real time, such as a piezoelectric water level sensor or a capacitive water level sensor. The first water level sensor 11 is installed below the side wall of the sewage chamber 2 and there is a gap between it and the bottom surface of the sewage chamber 2 to facilitate the installation and fixation of the first water level sensor 11.

[0049] In some embodiments of this application, a second water level sensor 12 is provided inside the sewage chamber 2. The second water level sensor 12 is located at the top of the sewage chamber 2 and is used to detect whether the sewage level in the sewage chamber 2 has reached a preset maximum water level. An inlet valve 23 is provided on the side wall of the sewage chamber 2, and a second controller is also provided inside the tank 1. Both the second water level sensor 12 and the inlet valve 23 are connected to the second controller. The second controller is used to control the inlet valve 23 to close when the second water level sensor 12 detects that the sewage level in the sewage chamber 2 has reached the preset maximum water level. With this structure, when the second water level sensor 12 does not detect that the sewage level in the sewage chamber 2 has reached the preset maximum water level, sewage from outside the tank 1 still needs to be introduced into the sewage chamber 2 through the inlet valve 23. At this time, the inlet valve 23 is opened by the second controller, so that sewage from outside the tank 1 can flow into the sewage chamber 2. When the second water level sensor 12 detects that the sewage level in the sewage chamber 2 has reached the preset maximum water level, the sewage chamber 2 no longer needs to be filled with sewage. At this time, the inlet valve 23 is closed by the second controller, so that the sewage chamber 2 is separated from the sewage outside the tank 1, so that the sewage outside the tank 1 will not flow into the sewage chamber 2.

[0050] In some embodiments of this application, the second water level sensor 12 is a device capable of converting the measured water level signal into an electrical signal in real time, such as a piezoelectric water level sensor or a capacitive water level sensor. The second water level sensor 12 is installed above the side wall of the sewage chamber 2 with a gap between it and the top surface of the sewage chamber 2 to facilitate the installation and fixation of the second water level sensor 12.

[0051] In some embodiments of this application, the first controller and the second controller can be two different controllers or the same controller.

[0052] In some embodiments of this application, the inlet valve 23 is provided with a filter screen, which can filter suspended particles and fibers in sewage.

[0053] In some embodiments of this application, such as Figure 1 and Figure 3As shown, the first needle-shaped electrode array 5 includes a positive electrode array and a negative electrode array arranged opposite each other. The positive electrode array includes multiple needle-shaped electrodes distributed along a first direction, and the negative electrode array includes multiple needle-shaped electrodes distributed along the first direction. Each needle-shaped electrode includes an electrode plate 51, an insulating layer 52, and a needle tip 53. The pulse power supply 6 is electrically connected to the electrode plate 51, and the needle tip 53 is electrically connected to the electrode plate 51. The insulating layer 52 wraps around the end of the needle tip 53 connected to the electrode plate 51. With this structure, after the sewage flows into the treatment chamber 4, it can sequentially pass through multiple needle-shaped electrodes on the positive and negative electrode arrays for pulse electrolysis, improving the purification effect of the treatment chamber 4 on the sewage. Specifically, the electrode plate 51 can provide pulse current to the needle tip 53, and the tip of the needle tip 53 can enhance the discharge intensity and increase the gap between two adjacent needle-shaped electrodes, allowing more sewage to flow through the tip of the needle tip 53. This results in more thorough and uniform contact between the sewage and the needle-shaped electrodes, further improving the purification effect of the treatment chamber 4 on the sewage. In addition, the insulating layer 52 can prevent mutual interference between two adjacent needles 53, increase the output frequency of the needle electrode, and reduce the additional capacitance effect.

[0054] In some embodiments of this application, the first direction is the height direction of the box 1.

[0055] In some embodiments of this application, the electrode plate 51 can be made of stainless steel or other corrosion-resistant conductors, the insulating layer 52 can be made of polytetrafluoroethylene (PTFE), modified polyoxymethylene (POM), polyphenylene sulfide (PPS) or other insulating materials, and the needle tip can be made of stainless steel or other corrosion-resistant conductors.

[0056] In some embodiments of this application, the housing 1 is further provided with an ozone chamber 13, a first gas pipe 14, and a second gas pipe 15; one end of the first gas pipe 14 is connected to the outside of the housing 1, and the other end is connected to the inlet end of the ozone chamber 13; one end of the second gas pipe 15 is connected to the outlet end of the ozone chamber 13, and the other end is connected to the inlet end of the processing chamber 4; a second needle-shaped electrode array 26 is provided in the ozone chamber 13, and ozone is generated when the gas in the first gas pipe 14 passes through the second needle-shaped electrode array 26, and the ozone is transmitted to the processing chamber 4 through the second gas pipe 15. With this structure, when the air in the first air tube 14 passes through the discharge gap between two adjacent needle electrodes in the second needle electrode array 26, the oxygen molecules in the air are excited by electrons, gain energy, and collide with each other to form ozone molecules. This allows the gas in the first air tube 14 to generate ozone when it passes through the second needle electrode array 26. The ozone is then transported to the treatment chamber 4 through the second air tube 15, where it can purify the wastewater in the treatment chamber 4, thereby further improving the purification effect of the treatment chamber 4 on wastewater.

[0057] In some embodiments of this application, the structure of the second needle electrode array 26 is the same as that of the first needle electrode array 5. The second needle electrode array 26 also consists of a positive electrode array and a negative electrode array. The positive electrode array includes a plurality of needle electrodes distributed along a first direction, and the negative electrode array includes a plurality of needle electrodes distributed along the first direction. The structure of the needle electrodes in the second needle electrode array 26 is the same as that of the needle electrodes in the first needle electrode array 5.

[0058] In some embodiments of this application, such as Figure 1 and Figure 4 As shown, a partition 16 is provided in the treatment chamber 4, which divides the treatment chamber 4 into a mixing chamber 41 and a reaction chamber 42. A first needle-shaped electrode array 5 is disposed in the reaction chamber 42. One end of the second gas pipe 15 is connected to the inlet end of the mixing chamber 41. The sewage chamber 2 is connected to the inlet end of the mixing chamber 41. The ozone in the second gas pipe 15 and the sewage in the sewage chamber 2 both flow into the mixing chamber 41. A nozzle 161 is provided on the partition 16. An air pump 18 is provided on the first gas pipe 14. The air pump 18 is used to pump the gas outside the box 1 into the ozone chamber 13 and apply air pressure to the mixing chamber 41 so that the water in the mixing chamber 41 is sprayed out in a mist form through the nozzle 161 into the reaction chamber 42. With this structure, water entering from the inlet of the treatment chamber 4 can be stored in the mixing chamber 41. At this time, the air pump 18 can pump the gas outside the housing 1 into the ozone chamber 13 to form ozone. The ozone flows through the second gas pipe 15 into the mixing chamber 41 to purify the water in the mixing chamber 41. At the same time, the gas in the ozone chamber 13 can pressurize the mixing chamber 41, so that a high-pressure environment can be formed in the mixing chamber 41. After being pressurized, the water in the mixing chamber 41 can be sprayed out in a mist from the nozzle 161 into the reaction chamber 42. Since the water in the mixing chamber 41 can have better contact with the first needle electrode array 5 after being sprayed out in a mist, the purification effect of the processor on sewage can be further improved, thereby further improving the purification effect of the sewage treatment device on sewage.

[0059] In some embodiments of this application, the partition 16 is a V-shaped plate, and the nozzle 161 is disposed in the middle of the V-shaped plate.

[0060] In some embodiments of this application, nozzle 161 is a high-pressure nozzle.

[0061] In some embodiments of this application, the housing 1 is provided with an air inlet 27, which is connected to a first air pipe 14, and gas outside the housing 1 can enter the ozone chamber 13 through the air inlet 27 and the first air pipe 14.

[0062] In some embodiments of this application, a third water level sensor 19 is provided on the upper part of the mixing chamber 41. The third water level sensor 19 is used to detect whether the water level in the mixing chamber 41 has reached a preset maximum water level. A third controller is also provided in the housing 1. The water pump 17 and the air pump 18 are both connected to the third controller. The third controller is used to control the water pump 17 to work and the air pump 18 to not work when the third water level sensor 19 does not detect whether the water level in the mixing chamber 41 has reached the preset maximum water level, and to control the air pump 18 to work and the water pump 17 to not work when the third water level sensor 19 detects whether the water level in the mixing chamber 41 has reached the preset maximum water level. With this structure, when the third water level sensor 19 fails to detect whether the water level in the mixing chamber 41 has reached the preset maximum water level, water still needs to be pumped into the mixing chamber 41 by the water inlet pump 17. At this time, the third controller controls the water inlet pump 17 to work and the air pump 18 to not work, so that the water inlet pump 17 can pump water into the mixing chamber 41 and ozone will not be delivered into the mixing chamber 41 to affect the pumping of water. When the third water level sensor 19 detects whether the water level in the mixing chamber 41 has reached the preset maximum water level, water no longer needs to be pumped into the mixing chamber 41. At this time, the third controller controls the air pump 18 to work and the water inlet pump 17 to stop working, so that the water inlet pump 17 can stop pumping water into the mixing chamber 41, and the air pump 18 can pump gas into the ozone chamber 13. The gas can form ozone after passing through the ozone chamber 13 and be transported to the mixing chamber 41 to sterilize and purify the water in the mixing chamber 41 and pressurize the mixing chamber 41, so that the water in the mixing chamber 41 can be sprayed out by the nozzle 161 under high pressure.

[0063] In some embodiments of this application, the third water level sensor 19 is a device capable of converting the measured water level signal into an electrical signal in real time, such as a piezoelectric water level sensor or a capacitive water level sensor. The third water level sensor 19 is installed at the upper opening of the mixing chamber 41.

[0064] In some embodiments of this application, the first controller, the second controller, and the third controller may be three different controllers or the same controller.

[0065] In some embodiments of this application, a vent pipe 20 for balancing internal and external air pressure is provided on the side wall of the reaction chamber 42. The vent pipe 20 includes an inclined section and a vertical section. One end of the inclined section is connected to the side wall of the reaction chamber 42, and the other end is offset away from the water purification chamber 3. One end of the vertical section is connected to the inclined section, and the other end extends away from the water purification chamber 3. With this structure, the reaction chamber 42 is connected to the atmosphere outside the housing 1 through the vent pipe 20, which can maintain the pressure balance inside the reaction chamber 42 and prevent pressure imbalance inside the reaction chamber 42 from affecting the normal operation of the sewage treatment device. When the vent pipe 20 includes an inclined section and a vertical section, it can prevent water inside the reaction chamber 42 from overflowing out of the vent pipe 20.

[0066] In some embodiments of this application, the housing 1 is further provided with a cooling pipe 21. The cooling pipe 21 is disposed on the outer surface of at least one of the ozone chamber 13 and the treatment chamber 4. The first needle-shaped electrode array 5 is disposed on the inner surface of the treatment chamber 4, and the second needle-shaped electrode array 26 is disposed on the inner surface of the ozone chamber 13. The inlet and outlet ends of the cooling pipe 21 are both connected to the purified water chamber 3. A cooling water pump 22 is provided on the cooling pipe 21, which is used to pump water from the purified water chamber 3 into the cooling pipe 21. With this structure, cooling water is pumped into the cooling pipe 21 by the cooling water pump 22. When the cooling water flows through the cooling pipe 21 past the outer surfaces of the ozone chamber 13 and the treatment chamber 4, it can cool down the ozone chamber 13 and the treatment chamber 4, preventing the second needle-shaped electrode array 26 in the ozone chamber 13 and the first needle-shaped electrode array 5 in the treatment chamber 4 from failing due to high temperature. It can also decompose the residual ozone in the purified water into oxygen, thereby improving the purification effect of the water.

[0067] In some embodiments of this application, the sidewalls of the ozone chamber 13 and the treatment chamber 4 can be metal cavity sidewalls, and the cavity structure inside the metal cavity sidewalls can form a cooling pipe 21 for the flow of cooling water.

[0068] In some embodiments of this application, the water purification chamber 3 is also provided with a water outlet valve 24, through which the water in the water purification chamber 3 can flow out, and the water outlet valve 24 is provided with a filter screen.

[0069] In some embodiments of this application, the housing 1 is also provided with a power module 25, which is connected to an external power source. The power module 25 can provide power to components such as the pulse power supply 6, the water inlet pump 17, the cooling water pump 22, and the air pump 18.

[0070] In some embodiments of this application, the wastewater treatment device is used as follows:

[0071] First, before starting the sewage treatment device, connect the power module 25 of the sewage treatment device to a 220V external power supply. Then, place the external connection pipe of the inlet valve 23 in the sewage chamber 2 into the external sewage and open the vent pipe 20 and the air inlet 27.

[0072] Next, turn on the power module 25 and check if the power indicator light is on normally. Adjust the voltage, frequency, and duration of the pulse power supply 6 according to the pollution level of the water to be purified, and start the equipment after confirming that everything is correct.

[0073] Next, the inlet pump 17 is started to operate, pumping sewage from outside the tank 1 into the sewage chamber 2. When the second water level sensor 12 detects that the sewage level in the sewage chamber 2 has reached the highest level, the inlet valve 23 is closed. Then, the valve 10 is activated to connect the first pipeline 7 and the second pipeline 8, and the sewage in the sewage chamber 2 is pumped into the mixing chamber 41 by the inlet pump 17. When the first water level sensor 11 detects that the sewage level in the sewage chamber 2 has reached the lowest level, the valve 10 is activated to connect the first pipeline 7 and the third pipeline 9.

[0074] Subsequently, when the third water level sensor 19 detects that the water level in the mixing chamber 41 has reached its maximum, it controls the inlet pump 17 to stop working and controls the air pump 18 to start working. When the air pump 18 is working, it pumps air into the ozone chamber 13. Oxygen in the air is discharged through the second needle electrode array 26 in the ozone chamber 13 to generate ozone. The ozone flows through the second gas pipe 15 to the mixing chamber 41 for purification. At the same time, the air pump 18 pumps gas in coordination with the nozzle 161, so that the water in the mixing chamber 41 is sprayed out in a mist form into the reaction chamber 42 through the nozzle 161. When the water level in the mixing chamber 41 decreases, the inlet pump 17 continues to work. When the mist-like sewage enters the reaction chamber 42, the mixing effect of the pulsed electric field and the ozone gas effectively purifies the pollutants such as bacteria and organic matter in the sewage. The purified water flows into the clean water chamber 3.

[0075] Then, the water in the purification chamber 3 is pumped into the mixing chamber by the water inlet pump 17, and the above steps are repeated until the water in the purification chamber 3 meets the purification requirements.

[0076] Then, the cooling water pump 22 is started, and the water in the purified water chamber 3 is pumped into the side wall cavity of the ozone chamber 13 and the treatment chamber 4 through the cooling water pump 22, so as to cool down the first needle electrode array 5 and the second needle electrode array 26, and at the same time, the residual ozone in the purified water can be decomposed into oxygen.

[0077] Finally, the water in the water purification chamber 3 is discharged through the outlet valve 24, completing the purification of the sewage.
