Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater purification and treatment device based on high-voltage discharge plasma. Background Technology

[0002] With increasingly stringent environmental protection requirements, the demand for more efficient, precise, and automated wastewater purification technologies is becoming increasingly urgent. High-voltage discharge plasma technology, with its multiple advantages including photocatalytic oxidation and electrochemical oxidation, lack of secondary pollution, and wide applicability, has attracted widespread attention in the field of wastewater treatment and has become one of the important research directions for deep wastewater purification.

[0003] Currently, existing wastewater purification technologies and related patented devices still have many shortcomings, making it difficult to meet the actual needs of different water qualities and large-scale treatment. This is especially true in plasma wastewater treatment, such as the corona discharge plasma wastewater treatment device (CN109889043B). Its technical focus is on optimizing the energy efficiency of the pulse power supply, but it cannot flexibly adjust the electric field strength according to the demand of different water qualities for plasma active particles. This results in poor device adaptability and easily leads to incomplete purification or energy waste. At the same time, most existing wastewater purification patents such as nano-cyclone and low-temperature plasma lack the synergistic design of plasma chemical purification and physical filtration. Even if some devices combine the two processes, it is difficult to achieve fully automated operation and maintenance, resulting in high workload for operators and limited treatment efficiency.

[0004] In addition, there are many types of existing plasma wastewater treatment devices, but many factors affect their reaction effect. The energy utilization efficiency and purification effect of different devices vary greatly, and most devices have not formed a perfect synergistic structure, resulting in insufficient continuity and stability of wastewater treatment, which further limits their practical application scope.

[0005] In view of the problems of poor adaptability, low purification efficiency, cumbersome impurity cleaning, and inconvenient operation and maintenance of the existing patents and technologies, the development of a high-voltage discharge plasma wastewater purification and treatment device that can achieve graded filtration, precise discharge, and automated operation and maintenance has become an urgent technical problem to be solved, hence this case.

[0032] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figure 1 - Figure 6 As shown, a wastewater purification treatment device based on high-voltage discharge plasma includes a treatment frame 1. Inside the treatment frame 1, from top to bottom, a liquid guiding frame 2, a liquid filter plate frame 1 3, a dynamic discharge module 4, a liquid filter plate frame 2 5, and a drain frame 6 are fixedly assembled. The liquid guiding frame 2, the liquid filter plate frame 1 3, the dynamic discharge module 4, the liquid filter plate frame 2 5, and the drain frame 6 are connected in sequence to form a wastewater purification channel. The same side of the liquid filter plate frame 1 3 and the liquid filter plate frame 2 5 are detachably connected to a dynamic pushing module 7. The feed end of the dynamic pushing module 7 is connected to the discharge side of the liquid filter plate frame 1 3 and the liquid filter plate frame 2 5 respectively. The liquid filter plate frame 1 3 and the liquid filter plate frame 2 5 are both set with a concave arc structure, and the center of their bottom surface is a mesh structure. The surface of the liquid filter plate frame 1 3 and the liquid filter plate frame 2 5 is provided with a discharge port on the side adjacent to the mesh surface.

[0034] The dynamic discharge module 4 includes a discharge frame 41 installed between the first liquid filter plate frame 3 and the second liquid filter plate frame 5. A liquid guide pipe is fixedly installed at the front end of the discharge frame 41, with one end of the liquid guide pipe corresponding to the surface of the second liquid filter plate frame 5. High-temperature resistant insulating plates are embedded in both the inner and outer walls of the discharge frame 41. An air compressor 42 is installed at the bottom of the discharge frame 41. An air pipe is fixedly connected to the output end of the air compressor 42, and the top of the air pipe extends to the inner central area of ​​the discharge frame 41 and is fixedly installed with an annular aeration head 43. Concave movable frames 44 are movably sleeved on both sides of the discharge frame 41, and the two are mirror symmetrical with respect to the central axis of the discharge frame 41. Long strip sliding frames 45 are fixedly installed at both the front and rear ends of the discharge frame 41. Sliding protrusions are integrally formed on the opposite ends of the two sets of concave movable frames 44, and the sliding protrusions are slidably adapted to the concave movable frames 44, so that the concave movable frames 44 can slide back and forth along the length direction of the discharge frame 41.

[0035] Metal electrode plates 46 are fixedly installed longitudinally inside the concave movable frame 44, and the metal electrode plates 46 are electrically connected to the external pulse power supply. Limiting plates 47 are fixedly installed at the rear end of the concave movable frame 44. Symmetrical inclined grooves 48 are provided on the surface of the two sets of limiting plates 47, and vertical shafts 49 are slidably connected to the inner end of the inclined grooves 48. Push plates 410 are fixedly installed on the top of the two sets of vertical shafts 49, and cylinder 411 is provided on the surface of the push plate 410 and the rear end of the discharge frame 41.

[0036] The specific workflow includes:

[0037] Pretreatment stage: First, the wastewater to be treated is introduced into the treatment frame 1. The wastewater first enters the liquid guiding frame 2, which guides and diverts the wastewater so that it flows relatively evenly to the liquid filter plate frame 3. The liquid filter plate frame 3 uses its concave arc structure and mesh structure to perform preliminary filtration of the wastewater, trapping larger particulate impurities on the surface and discharging them through the discharge port. The pre-filtered wastewater continues to flow downward to the discharge frame 41.

[0038] Discharge stage: First, the air compressor 42 is started, and air is aerated into the central area inside the discharge frame 41 through the air pipe and the annular aeration head 43. The liquid inside the discharge frame 41 generates countless small bubbles that rise continuously. At the same time, the external pulse power supply supplies power to the metal electrode plate 46, forcing the generation of high-voltage discharge plasma inside the discharge frame 41 to deeply purify the sewage. During the purification process, the adjustment of the electrode gap is essentially achieved by changing the electric field strength, depending on the different water qualities and their different requirements for plasma active particles. Therefore, by starting the cylinder 411 and pushing the push plate 410 to move, the push plate 410 drives the limiting plate 47 to move through the cooperation of the vertical shaft 49 and the inclined groove 48, thereby causing the concave movable frame 44 to slide back and forth along the concave movable frame 44. This adjusts the distance between the metal electrode plate 46 and the discharge frame 41, thereby changing the electric field strength to meet the different water qualities' requirements for plasma active particles and achieve more precise sewage purification.

[0039] Secondary filtration stage: The deeply purified wastewater continues to flow downwards and is filtered again through liquid filter plate frame 2 5 to further remove residual micro-impurities and ensure the quality of the effluent. Liquid filter plate frame 2 5 also adopts a concave arc structure and mesh design to effectively intercept impurities and discharge them through the discharge port. Finally, the wastewater that has undergone multi-stage purification and filtration flows into the discharge frame 6 and is discharged from the treatment device by the discharge frame 6, completing the entire wastewater purification treatment process.

[0040] Example 2: Please refer to Figure 3 - Figure 6 As shown, a concave top frame 412 is slidably connected to the rear end of the top of the discharge frame 41, and a cylinder 413 is provided at the rear end of the top frame 412 and the rear end of the surface of the discharge frame 41. A drive motor 414 is provided at the center of the top surface of the top frame 412. A transmission gear 415 is fixedly installed on the bottom output shaft of the drive motor 414. A baffle rod 416 is fixedly installed on the bottom of the transmission gear 415, and the outer wall of the baffle rod 416 is set in a spiral structure.

[0041] The top inner wall of the top frame 412 is located at the front end of the transmission gear 415, where a limiting gear 417 is engaged and rotated. An inverted T-shaped sleeve 418 is fixedly installed on one side of the bottom center of the limiting gear 417. A lifting rod 419 is laterally movably sleeved inside the inverted T-shaped sleeve 418. A concave swing frame 420 is fixedly sleeved outside the lifting rod 419. The bottom ends of both sides of the swing frame 420 are respectively hinged to the inner wall of the top frame 412. An insulating paddle 421 is fixedly installed on the top of the swing frame 420.

[0042] During the discharge phase, to improve discharge efficiency, the number of bubbles generated needs to be increased. However, since the aeration position is fixed, the bubble generation position is also relatively fixed. Therefore, by activating cylinder 413, the top frame 412 is pushed to slide along the top of the discharge frame 41 to the designated position. At this time, drive motor 414 drives transmission gear 415 to rotate. Transmission gear 415 meshes with limit gear 417, causing the inverted T-shaped sleeve 418 to generate eccentric motion. Then, the lifting rod 419 drives the concave swing frame 420 to swing back and forth around the hinge point. During the swing, the insulating plate 421 periodically cuts into the liquid surface inside the discharge frame 41, using mechanical disturbance to break the surface tension of the liquid and promote the diffusion of the bubble group. At the same time, the spiral structure of the turbulence rod 416 forms a local vortex when rotating, which makes the bubbles and liquid fully mix and accelerates the diffusion to all sides. Combined with the annular aeration head 43, a three-dimensional bubble distribution network is formed, which effectively expands the range of action of the high-voltage discharge plasma, significantly increases the amount of bubbles generated per unit time and the contact area with sewage, thereby improving the efficiency of plasma oxidation and decomposition of pollutants.

[0043] Example 3: Please refer to Figure 1 , Figure 7 - Figure 8 As shown, the dynamic feeding module 7 includes a mounting frame 71, a second drive motor 72, and a rotating drum 73. The mounting frame 71 is fixedly installed on the processing frame 1 on one side of the dynamic discharge module 4, and the second drive motor 72 is located on the inner wall of one side of the mounting frame 71. The rotating drum 73 is horizontally installed at the output shaft of the second drive motor 72, and a circumferential corrugated groove is provided in the middle section of the rotating drum 73. Feeding plates 74 are movably installed at both the upper and lower ends of the rotating drum 73, and movable shaft pins 75 are fixedly installed at the end positions of the feeding plates 74 relative to the rotating drum 73. One end of the movable shaft pin 75 is adapted to slide in the corrugated groove. The ends of the two sets of feeding plates 74 away from the movable shaft pins 75 slide in the corresponding liquid filter plate frame 3 and liquid filter plate frame 5 respectively and are arranged in a staggered fit with their mesh surfaces.

[0044] After purification: Drive motor 72 is started, and its output shaft drives the rotating drum 73 to rotate. Because the middle section of the rotating drum 73 has an circumferential corrugated groove, when the drum 73 rotates, the corrugated groove pushes the movable shaft pin 75 to slide within the groove, thereby causing the pusher plate 74 to reciprocate within the liquid filter plate frame 3 and the liquid filter plate frame 5. Since the pusher plate 74 is staggered and fitted to the screen surface, this reciprocating motion effectively scrapes off impurities trapped on the screen surface and discharges them out of the device through the discharge port. This design improves the efficiency of impurity removal and further enhances the automation and practicality of the entire wastewater purification treatment device. Simultaneously, the operation of the dynamic pusher module 7 does not interfere with the main process of wastewater purification treatment, ensuring stable operation and efficient purification effect of the device.

[0045] It is worth noting that the bottom of the drain frame 6 is fixedly connected to a drain pipe, and a solenoid valve is fixedly installed in the middle of the drain pipe. The outer wall of the processing frame 1 is fixedly installed with a control panel 8. The control panel 8 is electrically connected to the dynamic discharge module 4, the dynamic feeding module 7 and the solenoid valve respectively to realize automated control.

[0046] The control panel 8 is equipped with multiple operation buttons and a display screen. Operators can use the operation buttons to start or stop the operation of the device, adjust the discharge parameters of the dynamic discharge module 4, control the operating frequency and force of the dynamic feeding module 7, and control the opening and closing of the solenoid valve. The display screen can show the operating status of the device in real time, including the sewage treatment progress, plasma generation, and impurity removal, which is convenient for operators to monitor and manage. This automated control design not only improves the efficiency of sewage purification and treatment but also reduces the workload, making the entire device more intelligent and convenient.

[0047] Working principle: When using this invention, the wastewater to be treated is first introduced into the treatment frame 1. After being guided and diverted by the liquid guiding frame 2, the wastewater flows evenly to the liquid filter plate frame 3. The liquid filter plate frame 3 initially filters the wastewater through the concave arc-shaped mesh structure, intercepts large particulate impurities and discharges them through the discharge port. The pre-filtered wastewater flows into the discharge frame 41.

[0048] Upon entering the discharge stage, the air compressor 42 starts, aerating the center of the discharge frame 41 through the annular aeration head 43 to generate small bubbles; simultaneously, the pulse power supply powers the metal electrode plate 46, generating high-voltage discharge plasma to purify the wastewater; according to the water quality requirements, cylinder one 411 pushes the push plate 410, which drives the concave movable frame 44 to slide along the long strip sliding frame 45 through the vertical shaft 49 and the limiting plate 47, adjusting the distance between the metal electrode plate 46 and the discharge frame 41, changing the electric field strength to adapt to different water qualities; in addition, after cylinder two 413 pushes the top frame 412 into place, the drive motor one 414 drives the transmission gear 415 to rotate, which causes the inverted T-shaped sleeve 418 to move eccentrically through the limiting gear plate 417, causing the concave swing frame 420 to swing, the insulating paddle 421 disturbs the liquid surface to promote bubble diffusion, and the turbulence bar 416 rotates to form a vortex, which, together with the aeration, forms a three-dimensional bubble network, improving the purification efficiency.

[0049] After deep purification, the wastewater is filtered again through the liquid filter plate frame 5 to remove residual micro-impurities and is discharged through the discharge port. Then it flows into the drain box 6 for unified discharge, completing the purification process.

[0050] After purification, drive motor 72 drives the rotating drum 73 to rotate. The corrugated groove of the rotating drum 73 pushes the movable shaft pin 75, which drives the pusher plate 74 to reciprocate within the liquid filter plate frame 3 and the liquid filter plate frame 5, scraping off impurities from the screen and discharging them through the discharge port, thus improving the automation level of the device without interfering with the main process.

[0051] The bottom drain pipe of the drain box 6 is equipped with a solenoid valve. The control panel 8 on the outside of the processing box 1 is electrically connected to the dynamic discharge module 4, the dynamic pushing module 7 and the solenoid valve. Operators can adjust parameters and control the operation of the device through buttons. The display screen shows the operating status in real time, realizing automated management and control.
