Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and more specifically, to an industrial sewage electrolytic oxidation treatment system. Background Art

[0002] The pollutants contained in industrial wastewater mainly include metal or non-metal ions, organic matter, nitrogen, phosphorus compounds, etc. These pollutants are generally positively or negatively charged, and particles with the same charge repel each other, so it is difficult to condense and recover. Sewage electrolysis purification is an efficient and clean sewage treatment technology that is widely used in the treatment of industrial and domestic wastewater. This method uses electricity to electroflotate and electrolyze wastewater.

[0003] Electrolysis is a process that converts electrical energy into chemical energy to produce redox reactions near the electrodes in the electrolytic cell, thereby purifying wastewater. This water treatment method includes electrochemical action on the electrode surface, indirect oxidation and indirect reduction, electroflotation, electrocoagulation, etc. The advantages of electrolysis are: using low-voltage DC power supply, not consuming a large amount of chemical agents, simple operation, convenient management, and small footprint.

[0004] The electrolysis method for treating wastewater does not require the addition of chemical agents and can effectively remove pollutants. However, during long-term use, pollutants tend to directly adhere to the surface of the electrode to form dirt, causing the voltage formed between the electrodes to gradually decrease, and the effect of eliminating pollutants is also greatly reduced, which in turn leads to a shortened service life of the electrode and frequent replacement.

[0031] For example, see Figure 1-11 , the present invention provides the following technical solutions: An industrial wastewater electrolytic oxidation treatment system, specifically, comprises a treatment box 1 and an anode rod 2 and a cathode rod 3 which are arranged on the top of the treatment box 1; an insulating slide pipe 4 is symmetrically fixed on both sides of the anode rod 2 and the cathode rod 3 on the inner bottom surface of the treatment box 1; a cleaning part 5 is slidably arranged between two adjacent insulating slide pipes 4; an ozone generator 6 is installed on the inner bottom surface of the treatment box 1, and piston parts 7 are symmetrically arranged on the opposite sides; the cleaning part 5 comprises an annular cleaning sleeve 8 with a hollow structure inside; the inner wall of the annular cleaning sleeve 8 is close to the inner wall of the annular cleaning sleeve 8. A corrosion-resistant elastic diaphragm 9 is arranged near its inner bottom surface; the corrosion-resistant elastic diaphragm 9 divides the inside of the annular cleaning sleeve 8 into a liquid storage chamber 10 and an air storage chamber 11 from top to bottom; a corrosion-resistant liquid infusion hose 12 is arranged between the liquid storage chamber 10 and the piston part 7; a corrosion-resistant air delivery hose 13 is arranged between the air storage chamber 11 and the ozone generator 6; a plurality of exhaust pipes 14 are evenly penetrated and connected to the inner bottom surface of the air storage chamber 11; a first solenoid valve 15 and a one-way valve 16 are arranged on the exhaust pipe 14 from top to bottom.

[0032] The working principle of the first embodiment is as follows: the anode rod 2 is connected to the positive electrode of the external power supply, and the cathode rod 3 is connected to the negative electrode of the external power supply. After power is turned on, the sewage is oxidized to achieve sewage purification. By controlling the linkage between the various components, the annular cleaning sleeve 8 is made to perform reciprocating lifting and lowering motion along the corresponding insulating sliding pipe 4, thereby achieving periodic and automatic cleaning of scale on the anode rod 2 and the cathode rod 3. No human intervention is required throughout the process, and the adhesion of scale on the anode rod 2 and the cathode rod 3 is avoided, the voltage between the electrodes is guaranteed to be stable, the sewage electrolysis treatment effect is guaranteed, and the service life of the anode rod 2 and the cathode rod 3 is improved; ozone 50 is sent into the air storage chamber 11 through the ozone emitter 6. During the descent of the annular cleaning sleeve 8, the air storage chamber 11 sprays ozone 50 into the treatment box 1 through the exhaust pipes 14, thereby reducing the descent speed of the annular cleaning sleeve 8. At the same time, the ozone 50 reacts with the sewage in the treatment box 1, further improving the oxidation treatment effect of the sewage.

[0033] For example 2, please refer to Figure 1-11 , the second embodiment makes the following improvements on the basis of the first embodiment. Specifically, a sewage inlet pipe 17 is provided through the side of the treatment box 1, and a sewage outlet pipe 18 is provided through the inner bottom surface thereof; electromagnetic control valves are provided on the sewage outlet pipe 18 and the sewage inlet pipe 17; a control box 19 is installed on the top of the treatment box 1; the output end of the control box 19 is electrically connected to the first electromagnetic valve 15 and the electromagnetic control valve respectively; a plurality of sockets 20 are provided on the side of the control box 19; a plug 21 is inserted into the socket 20; each first electromagnetic valve 15 is electrically connected in series, and a cable 22 is electrically connected between it and the plug 21; the cable 22 is provided with a corrosion-resistant sheath 23 on the outside; a plurality of threading tubes 24 are provided through the top of the treatment box 1.

[0034] An upper baffle 25 and a lower baffle 26 are fixed to the side surfaces of the insulating slide tube 4 from top to bottom in sequence; a plurality of bristles 27 are evenly arranged on the inner side surface of the annular cleaning sleeve 8; and an ear seat 28 that slides with the insulating slide tube 4 is symmetrically fixed to the outer side surface of the annular cleaning sleeve 8.

[0035] An annular electromagnet 29 electrically connected to the output end of the control box 19 is installed on the side surface of the sewage outlet pipe 18; a lifting part 30 slidingly matched with the inside of the corresponding insulating slide pipe 4 is slidably arranged on the sewage outlet pipe 18; the lifting part 30 includes an iron ring 31 slidably arranged on the sewage outlet pipe 18; a reset spring 32 sleeved on the sewage outlet pipe 18 is fixedly connected between the iron ring 31 and the bottom surface of the treatment box 1; L-shaped rods 33 are symmetrically fixed on the side surface of the iron ring 31; a lifting block 34 slidingly matched with the inside of the insulating slide pipe 4 is fixed on the top of the L-shaped rod 33.

[0036] A guide tube 35 is fixed inside the insulating sliding tube 4; a slide plate 36 with a side surface designed as an inclined surface is slidably arranged between the inner walls of the guide tube 35; a first extrusion spring 37 is fixedly connected between the side surface of the slide plate 36 and the guide tube 35; an L-shaped guide rope tube 38 is penetrated through the bottom surface of the guide tube 35; a connecting rope 39 that passes through the L-shaped guide rope tube 38 is connected between the slide plate 36 and the lifting block 34.

[0037] The piston part 7 includes a drain pipe 40 which is arranged through the side of the processing box 1; one end of the drain pipe 40 is connected to a piston cylinder 41; a piston plate 42 is slidably arranged inside the piston cylinder 41; a second extrusion spring 43 is fixedly connected between the piston plate 42 and the piston cylinder 41; a liquid inlet pipe 54 is arranged through the top of the annular cleaning sleeve 8; a second solenoid valve 44 is arranged on the drain pipe 40, and the other end thereof is connected to the liquid inlet pipe 54 through a corrosion-resistant infusion hose 12; water 45 is filled between the piston cylinder 41, the corrosion-resistant infusion hose 12 and the liquid storage chamber 10.

[0038] An air inlet pipe 46 is provided through the bottom surface of the annular cleaning sleeve 8; a plurality of ear tubes 47 are provided in communication with the output end of the ozone generator 6; a connecting pipe 48 is symmetrically provided through the bottom surface of the treatment box 1; one end of the connecting pipe 48 is connected to the air inlet pipe 46 through a corrosion-resistant gas supply hose 13, and an exhaust hose 49 is connected between the other end thereof and the corresponding ear tube 47; the interior of the air storage chamber 11 is filled with ozone 50 through the air inlet pipe 46.

[0039] Working principle of the second embodiment: Initial state input Figure 4 As shown, the piston plate 42 squeezes the water in the piston cylinder 41 into the liquid storage chamber 10 under the elastic force of the second extrusion spring 43, the liquid storage chamber 10 inside the annular cleaning sleeve 8 is filled with water 45, and the corrosion-resistant elastic diaphragm 9 is compressed and deformed to press against the bottom surface of the air storage chamber 11. At this time, the ear seat 28 is placed between the slide plate 36 and the lower baffle plate 26, and the annular cleaning sleeve 8 cannot be raised or lowered along the insulating slide tube 4.

[0040] By controlling the start-up of the ozone generator 6, the generated ozone 50 enters the air storage chamber 11 through the ear tube 47, the exhaust hose 49, the connecting pipe 48, the corrosion-resistant air delivery hose 13 and the air inlet pipe 46 in turn. As the ozone 50 in the air storage chamber 11 gradually increases, the second solenoid valve 44 is controlled to open, and the corrosion-resistant elastic diaphragm 9 is squeezed by the gradually increasing ozone 50 and deforms upward. The continuously increasing ozone 50 squeezes the water 45 in the liquid storage chamber 10 into the piston cylinder 41, so that the overall weight of the cleaning part 5 decreases, and the gravity is less than the buoyancy. After the water 45 in the liquid storage chamber 10 is discharged into the piston cylinder 41, the second solenoid valve 44 is controlled to be closed, and the annular electromagnet 29 is controlled to be energized to attract the iron ring 31 above, and the reset spring 32 is stretched. During the descent of the iron ring 31, the lifting and lowering The block 34 slides down along the inside of the corresponding insulating slide tube 4, the connecting rope is gradually tightened, and the slide plate 36 is pulled by the connecting rope 39 to slide toward the inside of the guide tube 35. The first extrusion spring 37 is compressed, and the limit on the annular cleaning sleeve 8 is released. Under the action of buoyancy, the annular cleaning sleeve 8 slides up along the corresponding insulating slide tube 4, thereby driving the bristles 27 to clean the corresponding anode rod 2 and cathode rod 3. During the rising process of the cleaning part 5, the annular electromagnet 29 is controlled to lose power. Under the elastic reset force of the reset spring 32, the iron ring 31 rises along the sewage outlet pipe 18, the connecting rope 39 becomes loose, and under the elastic force of the first extrusion spring 37, the slide plate 36 slides out of the guide tube 35. During this process, the first solenoid valve 15 on the exhaust pipe 14 is in a closed state.

[0041] The second solenoid valve 44 is controlled to open, and under the elastic restoring force of the second extrusion spring 43 and the corrosion-resistant elastic diaphragm 9, water 45 is injected from the piston cylinder 41 into the liquid storage chamber 10. As the water 45 in the liquid storage chamber 10 gradually increases, when the total weight of the cleaning part 5 together with the water 45 therein is greater than the buoyancy, the annular cleaning sleeve 8 opens and slides downward. During the sliding process, the bristles 27 clean the corresponding anode rods 2 and cathode rods 3. While controlling the second solenoid valve 44 to open, each group of first solenoid valves 15 is controlled to open. Through the setting of the one-way valve, the ozone 50 in the air storage chamber 11 can only be discharged into the sewage through the exhaust pipe 14. The ozone 50 discharged into the sewage reduces the descending speed of the annular cleaning sleeve 8 to prevent it from descending too fast and causing damage. At the same time, the ozone 50 reacts with the sewage to improve the oxidation treatment capacity of the sewage.

[0042] When the ear seat 28 on the annular cleaning sleeve 8 drops to contact the inclined surface of the slide plate 36, the ear seat 28 continues to drop, squeezing the slide plate 36 to slide toward the inside of the guide tube 35. When the ear seat 28 is separated from the inclined surface of the slide plate 36, the slide plate 36 is driven to slide out of the guide tube 35 under the elastic return force of the first squeezing spring 37, thereby realizing automatic restriction of the ear seat 28.

[0043] For example 3, please refer to Figure 1-11 The third embodiment makes the following improvements on the basis of the second embodiment. Specifically, a driving motor 51 is fixedly installed on the top of the processing box 1; the output end of the control box 19 is electrically connected to the driving motor 51; a rotating shaft 52 is fixed to the output end of the driving motor 51; and a plurality of stirring rods 53 are fixed to the side surface of the rotating shaft 52.

[0044] Working principle of the third embodiment of the present invention: during the descent of the annular cleaning sleeve, the air storage chamber 11 sprays ozone 50 into the treatment box 1 through the exhaust pipes 14, thereby reducing the descent speed of the annular cleaning sleeve 8. At the same time, the driving motor 51 is controlled to start, and the stirring rod 53 is driven by the rotating shaft 52 to stir the sewage, so that the ozone 50 fully reacts with the sewage, thereby further improving the oxidation treatment effect of the sewage.
