Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, in particular to sewage catalytic oxidation treatment equipment. Background Art

[0002] In the field of sewage treatment, sewage oxidation treatment processes are commonly used. Treatment methods can be divided into chemical oxidation and physical oxidation. Chemical oxidation has a sterilizing and disinfecting effect. Through oxidative catalysis, organic matter in sewage can be rapidly oxidized into carbon dioxide, water, nitrogen dioxide, and other substances. Chemical oxidation can also convert non-biodegradable substances in sewage into biodegradable substances, thereby increasing dissolved oxygen in sewage to reduce odor. It can also convert colored substances in wastewater into colorless substances to increase transparency.

[0003] After searching, the existing technology was found: the publication number is CN217578415U, which discloses a sewage catalytic oxidation treatment tower, which relates to sewage treatment equipment, including a reactor body, the reactor body includes a cylindrical tower body, the upper part of the tower body is provided with a buffer drainage chamber, and the lower part is provided with a water inlet chamber; at least two reaction sections are provided between the buffer drainage chamber and the water inlet chamber; the reaction section includes a No. 1 reaction chamber and a No. 2 reaction chamber, the lower part of the No. 1 reaction chamber is connected with the No. 2 reaction chamber below or the upper part of the water inlet chamber through the water inlet pipe hole, the lower part of the No. 2 reaction chamber is connected with the upper part of the No. 1 reaction chamber below through the upper water hole on the bottom plate, the buffer drainage chamber is evenly provided with upper water holes on the bottom plate, and its lower part is connected with the upper part of the No. 2 reaction chamber through the upper water hole; it has the advantages of a long sewage flow path, sufficient reaction, sufficient contact between the sewage and the catalyst, filler and other substances in the reaction chamber, no dead angle in the reaction chamber, and high space and material utilization.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1 to 4 , the present invention provides two embodiments:

[0024] Example 1:

[0025] A sewage catalytic oxidation treatment device includes a treatment tank 2, a conical pipe 4, a return pipe 6, a transmission box 12, a fixing ring 14, a diversion groove 19, and a diversion pipe 20. The treatment tank 2 is provided with equidistantly distributed conical pipes 4 inside. The transmission box 12 is provided above the conical pipes 4. The bottom end of the transmission box 12 is provided with a first transmission shaft 18 that runs through the interior of the conical pipes 4. The top of the conical pipe 4 is provided with a diversion groove 19. The inner wall of the conical pipe 4 is provided with a diversion pipe 20. The outer wall of the diversion groove 19 is embedded with second nozzles 26 distributed in a circular array, and the second nozzles 26 are at the same angle as the surface of the conical pipe 4. The top of the treatment tank 2 is connected to a drain pipe 5, and the lower surface of the drain pipe 5 is connected to the return pipe 6. The inner wall of the diversion groove 19 is connected to a first connecting pipe 23, which passes through the outer wall of the treatment tank 2 and is connected to the return pipe 6. The return pipe 6 is provided with a solenoid valve 15 and a booster pump 16. First nozzles 25, arranged in a circular array, are embedded in the outer wall of diverter pipe 20 and extend through the surface of conical pipe 4. A second connecting pipe 24 is connected to the inner wall of diverter pipe 20, which extends through the outer wall of treatment tank 2 and is connected to a gas pipe 7 at one end. Sewage is fed into treatment tank 2 through water inlet 1. As the sewage level rises within tank 2, it passes through conical pipes 4 at different heights. Gas pipe 7 delivers ozone to diverter pipe 20, and a sub-controller 9 energizes electrodes 8, subjecting the sewage in the space above conical pipe 4 to both ozone oxidation and electrolytic oxidation, effectively improving the oxidation treatment effect.

[0026] Example 2:

[0027] The inner wall of the treatment tank 2 is provided with evenly spaced fixed rings 14, and a sub-controller 9 is installed on one side of the fixed rings 14. The fixed rings 14 are all located above the conical tube 4, and the lower surface of the fixed rings 14 is connected to the electrodes 8 arranged in a circular array. A motor 10 is installed above the sub-controller 9, and a first impeller 11 and a second impeller 13 are installed on the surface of the first transmission shaft 18. Fixed tubes 27 arranged in a circular array are connected between the outer walls of the transmission box 12 and the treatment tank 2. A second transmission shaft 30 is installed on one side of the motor 10, which runs through the fixed tubes 27 and the interior of the transmission box 12. A driving gear 29 is installed at one end of the second transmission shaft 30, and a driven gear 28 is installed at the upper end of the first transmission shaft 18, and the driving gear 29 and the driven gear 28 are meshed. The first impeller 11 is located above the fixed ring 14, and the second impeller 13 is located below the fixed ring 14. The rotation radius of the second impeller 13 is smaller than that of the first impeller 11. The bottom end of the first transmission shaft 18 is rotatably sleeved with an end block 22, and brackets 21 distributed in a circular array are welded between the outer wall of the end block 22 and the inner wall of the conical tube 4. The first transmission shaft 18 passes through the outer wall of the bottom end of the transmission box 12 and is sleeved with a shaft sleeve 31. The first impeller 11 and the second impeller 13 above the conical tube 4 rotate to generate a countercurrent of water, slow down the sewage transportation speed, and disperse the water flow, so that the residence time of the sewage above the conical tube 4 is increased, and it can be fully contacted with the ozone sprayed by the electrode 8 and the first nozzle 25, effectively increasing the comprehensiveness and oxidation effect of the sewage oxidation.

[0028] The bottom of the treatment tank 2 is provided with a water inlet 1, and a sewage discharge pipe 17 is provided on the outer wall of one side of the treatment tank 2, and the sewage discharge pipe 17 is flush with the bottom surface of the conical tube 4. The sub-controller 9 and the motor 10 are both electrically connected to the controller 3. Different liquid levels in the treatment tank 2 are independently controlled, so that the rotation speed of the first impeller 11 and the second impeller 13 in the space above the conical tube 4 and the electrolysis efficiency of the electrode 8 can be flexibly controlled to adapt to different polluted water conditions, making actual use more flexible and achieving better oxidation treatment effects on sewage.

[0029] During actual use, sewage is input into the treatment tank 2 through the water inlet 1. The sewage level rises in the treatment tank 2 and passes through the cones 4 at different heights. The gas pipe 7 inputs ozone into the diversion pipe 20, and the sub-controller 9 controls the power supply of the electrode 8 to perform ozone oxidation and electrolytic oxidation on the sewage in the space above the cone 4. The rotation of the first impeller 11 and the second impeller 13 above the cone 4 can generate a countercurrent flow, slowing the sewage delivery speed and dispersing the water flow, thereby increasing the retention time of the sewage above the cone 4 and allowing it to fully contact the ozone sprayed by the electrode 8 and the first nozzle 25, effectively increasing the comprehensiveness and oxidation effect of the sewage. In addition, the rotation speed of the first impeller 11 and the second impeller 13 in the space above the cone 4 and the electrolysis efficiency of the electrode 8 can be flexibly controlled according to the different liquid level heights in the treatment tank 2. This can adapt to polluted water in different situations, making actual use more flexible and achieving better sewage oxidation treatment results.
