Technical Field

[0001] The invention belongs to the technical field of sewage electrocoagulation treatment, and in particular relates to an electrocoagulation device capable of cleaning anode plates in real time. Background Art

[0002] Electrocoagulation technology removes pollutants from wastewater through the principles of electrochemical oxidation, flocculation and flotation. It has the advantages of simple equipment structure, small footprint, short hydraulic retention time, easy operation and maintenance, no secondary pollution, and high pollutant removal efficiency. It has been considered to be an efficient and promising new technology for wastewater treatment.

[0003] However, the following problems exist in the operation of electrocoagulation technology, which have a significant impact on the sewage treatment effect of electrocoagulation:

DETAILED DESCRIPTION

[0034] This embodiment provides an electrocoagulation device capable of cleaning anode plates in real time. Figures 1-10 As shown, it includes an electric flocculation cell body 1 and a plurality of anode plates 2 and cathode plates 3 alternately arranged therein. The anode plates 2 and cathode plates 3 are all arranged horizontally. A water distribution pipe 4 and an aeration pipe 5 are provided at the bottom of the electric flocculation cell body 1, a water outlet pipe 6 is provided at the top, and a stirring device is provided inside the electric flocculation cell body 1.

[0035] The anode plate 2 covers the horizontal cross section of the electro-flocculation cell 1 and is provided with a plurality of through holes for sewage to pass through the anode plate 2. A gap 23 is provided between one side of the cathode plate 3 and the inner wall of the electro-flocculation cell 1 for sewage to pass through the cathode plate 3.

[0036] The stirring device includes a plurality of stirring paddles, which are located above the anode plate 2 and are used to clean the flocculants above the anode plate 2 when the stirring paddles rotate.

[0037] Optionally, the aeration pipe 5 is located below the water distribution pipe 4. The aeration pipe 5 is connected to the air source outside the electric flocculation cell 1 to provide air and oxygen to the inside of the electric flocculation cell 1. The aeration pipe 5 is preferably a spiral aeration pipe, which can uniformly aerate the cell body, promote the disturbance and rise of sewage, and fully contact with the anode and cathode plates to improve the treatment efficiency.

[0038] Optionally, the water distribution pipe 4 is connected to the sewage source outside the electroflocculation cell 1 for inputting sewage into the cell. The water distribution pipe 4 is preferably in the form of a pipe that can cover the cross section of the electroflocculation cell 1, which is conducive to uniform water inflow into the cell.

[0039] Sewage is fed into the bottom of the electroflocculation cell 1. Driven by water flow and aeration, it flows upward, passing through the horizontally arranged anode and cathode plates. Under the influence of the external electric field, the anode plate dissolves and produces metal ions. These ions undergo hydrolysis and polymerization to form a series of mononuclear and polynuclear hydroxyl complexes and hydroxides. This process removes pollutants from the water through flocculation, adsorption, and precipitation. Simultaneously, a reduction reaction occurs at the cathode, producing tiny hydrogen bubbles. These bubbles separate pollutants from the water through flotation and bring them to the surface for removal.

[0040] Optionally, a cathode plate 3 is provided between two adjacent anode plates 2, the number of anode plates 2 and cathode plates 3 is equal, and both are connected to a power supply device outside the electro-flocculation cell 1 through a circuit;

[0041] The electro-flocculation cell body 1 is cylindrical, and the anode plate 2 is circular.

[0042] Optionally, the anode plate 2 has a plurality of water flow mechanisms 7, each of which passes through the center of the anode plate 2 along the diameter of the anode plate 2, that is, the plurality of water flow mechanisms 7 pass through the center of the anode plate 2 and are evenly distributed on the anode plate 2 in a radial shape;

[0043] Each set of water flow mechanisms 7 includes a plurality of through holes 8, which are evenly distributed along the diameter of the anode plate 2 and penetrate the upper and lower surfaces of the anode plate 2, allowing sewage below to pass through the anode plate 2 through the through holes.

[0044] Optionally, the first stirring paddle 9 includes a plurality of first blades 11, which all pass through the center of the first stirring paddle 9 and are evenly distributed in a radial pattern. A plurality of protruding balls 13 are evenly provided on the lower surface of each first blade 11. When the first blade 11 rotates, the water flow above the anode plate 2 is disturbed to avoid the accumulation of flocs above the anode plate 2. The balls 13 contact the upper surface of the anode plate 2 to reduce the resistance to the rotation of the stirring paddle.

[0045] Optionally, a plurality of water-passing conical holes 14 are evenly provided on the lower surface of the anode plate 2, and a plurality of groups of water-passing holes 15 are evenly provided on the upper surface of the anode plate 2, with one water-passing conical hole 14 corresponding to one group of water-passing holes 15; each group of water-passing holes 15 includes a plurality of inclined holes 16 arranged obliquely, and the tops of the plurality of inclined holes 16 in each group of water-passing holes 15 form a circle on the upper surface of the anode plate 2, and the remaining portions of the inclined holes 16 are inside the anode plate 2;

[0046] The bottoms of the inclined holes 16 in the same group are all connected to the tops of the corresponding water-passing conical holes 14 , so that sewage passes through the anode plate 2 via the water-passing conical holes 14 and the inclined holes 16 .

[0047] Further optionally, the water conical hole 14 is a conical shape with a small top and a large bottom, and a continuous thread is evenly provided on the inner wall. When the sewage enters the water conical hole 14, it plays a certain diversion and rectification role, that is, the sewage spirals upward along the inner wall of the water conical hole 14 and enters the anode plate 2, and then discharges the anode plate 2 through the inclined hole 16;

[0048] The bottoms of the inclined holes 16 in the same group are connected to each other to form a unified water inlet position, and the tops of the water-passing conical holes 14 are connected to the corresponding inclined holes 16 in the same group through the water inlet position.

[0049] Further optionally, the tops of the several inclined holes 16 of each group of water holes 15 form a circle on the upper surface of the anode plate 2, and the center of the circle coincides with the center of the bottom surface of the water conical hole 14, ensuring that the water conical hole 14 evenly supplies water to each inclined hole 16.

[0050] Since the water-passing conical holes 14 are small at the top and large at the bottom, the sewage is accelerated after passing through the water-passing conical holes 14, and then is evenly distributed into the corresponding several inclined holes 16, and output from the anode plate 2 along the inclined holes 16 inside the anode plate 2. Since the tops of the inclined holes 16 of the same group are circular, the inclined directions of the channels of the same group of inclined holes 16 are different, so that the spiral accelerated water flow that has just left the water-passing conical holes 14 randomly enters channels in different directions, and is output from the anode plate 2 in different directions, resulting in a disturbed water flow with rich dimensions, which improves the efficiency of electrical treatment. In addition, the water flow can clean the flocs formed or accumulated above the anode plate 2, and promote the flocs to rise.

[0051] Optionally, a liftable cleaning plate 17 is provided under the anode plate 2, and the cleaning plate 17 includes an external circular frame 18 and several internal cleaning cones 19, each cleaning cone 19 corresponds to a water-passing conical hole 14, and the cleaning cone 19 can rotate in situ, and a protruding external thread is provided on the surface. The shape of the cleaning cone 19 is adapted to the shape of the water-passing conical hole 14, and the protruding external thread of the cleaning cone 19 is adapted to the thread on the inner wall of the water-passing conical hole 14. When the cleaning plate 17 rises, the cleaning cone 19 can penetrate into the water-passing conical hole 14 to clean the inner wall of the water-passing conical hole 14.

[0052] Further optionally, the cleaning cone 19 has a flexible shell that can be elastically deformed and is hollow inside to reduce its own weight and reduce energy consumption during rotation. A rotating motor is provided below the cleaning cone 19, and a rotating shaft of the rotating motor is connected to the bottom of the cleaning cone 19 for driving the cleaning cone 19 to rotate;

[0053] The outside of the rotating motor also has an outer shell, which is connected to the outer shell of the cleaning cone 19 to prevent sewage in the electric flocculation cell body 1 from entering the outer shell.

[0054] Further optionally, the cleaning plate 17 is a hollow structure, and the interior of the circular frame 18 is supported by several support rods 20 for each cleaning cone 19 and its corresponding rotating motor. The specific arrangement of the support rods 20 is not limited, and it is sufficient to ensure that the cleaning cone 19 and the rotating motor are stable. Other hollow positions are used for sewage to pass through the cleaning plate 17.

[0055] Further optionally, a horizontal circular track and a plurality of vertical tracks are provided on the inner wall of the electro-flocculation cell body 1 below the anode plate 2. The plurality of vertical tracks are evenly arranged along the circumference of the inner wall of the electro-flocculation cell body 1. A slider 21 is clamped in each vertical track. The outer side surface of the circular frame 18 is connected to all the sliders 21, so that the cleaning plate 17 can move up and down along the vertical track. At this time, the cleaning cone 19 on the cleaning plate 17 corresponds to the position of the water-passing conical hole 14 on the lower surface of the anode plate 2 one by one; the top of the vertical track is close to the lower surface of the anode plate 2.

[0056] The horizontal circular track is arranged horizontally and winds around the inner wall of the electro-flocculation cell 1. Each vertical track penetrates and connects the horizontal circular track in its own vertical direction.

[0057] The distance between the horizontal circular track and the lower surface of the anode plate 2 is smaller than the height of the cleaning cone 19 .

[0058] During normal sewage treatment, the cleaning plate 17 is located below the second horizontal circular track, and the cleaning plate 17 as a whole does not contact the anode plate 2. At this time, the height position of the cleaning plate 17 is at the bottom of each vertical track and cannot move downward any further, thus playing a limiting role. Since the water-passing conical hole 14 is the only way for sewage to pass through, after a period of operation, an oxide film will form on the inner wall of the water-passing conical hole 14, which needs to be cleaned. The control slider 21 drives the cleaning plate 17 to move up along the vertical track to the top of the vertical track. At this time, the cleaning cone 19 just extends into the corresponding water-passing conical hole 14, and fits the inner wall of the water-passing conical hole 14 through the cooperation of internal and external threads. At this time, the cleaning plate 17 cannot move upward any further, thus playing a limiting role. Each cleaning cone 19 rotates separately to clean the oxide film on the inner wall of the water-passing conical hole 14. After cleaning, the cleaning plate 17 moves downward along the vertical guide rail and separates from the anode plate 2. If the cleaning time is short, it can be divided into multiple cleanings without affecting the water inlet and water flow of the electroflocculation cell 1, and the sewage can be treated continuously. If the cleaning time is long, it will affect the water flow of the water conical hole 14, and the water inlet needs to be stopped.

[0059] When the electro-flocculation cell 1 has been running for a long time, an oxide film accumulates on the lower surface of the anode plate 2 and needs to be cleaned. The cleaning plate 17 moves upward along the vertical guide rail to the horizontal circular track. At this time, the cleaning cone 19 partially extends into the water-passing conical hole 14. The cleaning plate 17 is controlled to rotate horizontally along the horizontal circular track. When the cleaning cone 19 faces the position of the anode plate 2 where the water-passing conical hole 14 is not located, the cleaning cone 19 is pressed and presses against the lower surface of the anode plate 2. As the cleaning plate 17 rotates, the cleaning cone 19 can clean the lower surface of the anode plate 2.

[0060] Optionally, the second stirring paddle 10 located above the anode plate 2 includes a plurality of second blades 12, and the plurality of second blades 12 all pass through the center of the second stirring paddle 10 and are evenly distributed radially. Two rows of brushes 22 are provided on the lower surface of each second blade 12, and the roots of the brushes 22 are parallel to each other. The bristles of the two rows of brushes 22 are inclined toward each other, and the inclination angle of the bristles is the same as the inclination angle of the inclined hole 16, which is used to clean the inside of the inclined hole 16 on the anode plate 2 and the upper surface of the anode plate 2.

[0061] Further optionally, the stirring shaft of the stirring device passes through the top surface of the electroflocculation cell body 1 and is connected to an external motor. The motor as a whole can adjust the upper and lower positions, thereby adjusting the distance between the first stirring paddle 9 or the second stirring paddle 10 and the lower surface of the anode plate 2, so that when the anode plate 2 does not need to be cleaned, the first stirring paddle 9 or the second stirring paddle 10 is raised, and the brush 22 or the ball 13 does not contact the anode plate 2.

[0062] When the second stirring paddle 10 rotates, the inclined bristles can extend into the inclined hole 16 along the tangential direction to clean the oxide film in the inclined hole 16. Since the bristles are soft and deformable, they can easily enter and exit the inclined hole 16 and can also clean the oxide film on the upper surface of the anode plate 2.

[0063] Optionally, the ratio of the width of the gap 23 between the cathode plate 3 and the inner wall of the electro-flocculation cell 1 to the radius of the cathode plate 3 is 1:(2-6), so that the rising sewage passes through the cathode plate 3 through the gap 23;

[0064] The positions of the gaps 23 of the two adjacent cathode plates 3 are relative. For example, the gap 23 of the lower cathode plate 3 is located on the right, and the gap 23 of the upper cathode plate 3 is located on the left, so that the sewage flow forms a tortuous flow between the cathode plates 3, thereby extending the residence time of the sewage and improving the treatment effect.

[0065] The first stirring paddle 9 and the second stirring paddle 10 are both located above the anode plate, in the same position but with different structures. The stirring paddles penetrate each anode plate and cathode plate.
