Technical Field

[0001] The utility model relates to the field of ozone disinfection equipment, in particular to an ozone catalytic oxidation contact pool. Background Art

[0002] Ozone catalytic oxidation technology is an efficient wastewater deep treatment technology and has been a hot application in the field of wastewater treatment in recent years. Compared with ozone as a single oxidant, the hydroxyl radicals formed by ozone under the action of a catalyst have a higher reaction rate with organic matter and stronger oxidizing properties, and can oxidize almost all organic matter. The catalyst can catalyze ozone to directly oxidize organic matter in water into CO2 and H2O, or oxidize and decompose large molecular organic matter into small molecules, making it easier to degrade.

[0003] In the existing ozone catalytic oxidation equipment for sewage treatment, during operation, ozone and sewage mostly enter the treatment equipment through aeration equipment and water distribution pipes, and as the water level rises, they pass through the catalyst packing layer to purify the pollutants in the sewage. If the sewage treatment volume is large, it takes a certain amount of time for a large amount of sewage to merge with ozone inside the large treatment equipment. In addition, since the position of ozone entering the treatment equipment is fixed, it is easy to reduce the speed of sewage and ozone fusion, reduce the efficiency of sewage treatment, and easily cause incomplete purification.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: Reference Figure 1 , Figure 2 and Figure 3 An ozone catalytic oxidation contact tank shown includes a contact tank 1, a cavity for contacting sewage and ozone is formed inside the contact tank 1, a catalytic filler layer 5 and a pair of rotatable linkage frames 6 are arranged from top to bottom in the inner cavity of the contact tank 1, and the opposite sides of the linkage frames 6 are fixed by a plurality of equally distributed connecting rods 7. During the rotation of the linkage frames 6, the sewage inside the contact tank 1 can be stirred, the fluidity of the sewage can be improved, the flow of the sewage can be accelerated, and the ozone can be guided to dissolve in the sewage at different positions inside the contact tank 1.

[0023] It also includes a plurality of alignment rods 8 arranged in the relative space of a pair of linkage frames 6, both ends of the alignment rods 8 are installed on the inner wall of the contact pool 1, and a rotatable follower frame 9 is sleeved on the surface of the alignment rod 8. The surface of the follower frame 9 is an inferior arc structure, and the top of the follower frame 9 abuts against the surface of the connecting rod 7 and is close to the lower position. When the linkage frame 6 rotates, the connecting rod 7 squeezes the follower frame 9 and rotates around the alignment rod 8. With the reciprocating rotation of the linkage frame 6, the follower frame 9 can reciprocate.

[0024] When the linkage frame 6 is in a reciprocating rotation state, it can continuously move the sewage inside the contact tank 1, causing a large amount of sewage to quickly contact the ozone inside the contact tank 1, effectively expanding the contact area between the sewage and ozone, and improving the fusion efficiency of ozone and sewage. It can also effectively avoid the precipitation of impurities at the bottom of the sewage, thereby improving the comprehensiveness of the ozone purification work and improving the ozone purification efficiency.

[0025] like Figure 1 , Figure 2 and Figure 3As shown, the side wall of the contact tank 1 is installed with an aeration pipe 2 and a water inlet pipe 4 which are connected to the inner cavity thereof, and the end of the aeration pipe 2 away from the contact tank 1 is connected with an ozone generator 3, and the aeration pipe 2 and the water inlet pipe 4 are both located below the catalytic packing layer 5. After the sewage and ozone enter the inner side of the contact tank 1 through the water inlet pipe 4 and the aeration pipe 2, the ozone is integrated into the sewage and continuously rises, and passes through the catalytic packing layer 5, and a large amount of hydroxyl groups and free radicals are generated under the catalytic action, which mineralizes the macromolecules, long chains and difficult-to-decompose pollutants in the sewage, or decomposes them into small molecules and easily degradable organic matter, so as to achieve a good purification effect.

[0026] like Figure 4 , Figure 5 As shown, the edges of the linkage frame 6 are provided with accommodating channels 61 for accommodating the alignment rod 8 to pass through. When the linkage frame 6 rotates, the relative positions of the accommodating channels 61 and the alignment rod 8 change, so that the linkage frame 6 can rotate smoothly.

[0027] like Figure 4 , Figure 5 As shown, the surface of the follower frame 9 is in a comb-tooth structure, and the downward end of the follower frame 9 is fixedly connected to a counterweight 10. After the connecting rod 7 squeezes the follower frame 9 to rotate around the alignment rod 8, the connecting rod 7 can return to the original position with the repeated rotation of the linkage frame 6 and the connecting rod 7, and the squeezing of the follower frame 9 is released. At this time, under the gravity of the counterweight 10, the follower frame 9 returns to its original position.

[0028] Therefore, as the linkage frame 6 and the connecting rod 7 rotate repeatedly, the connecting rod 7 can continuously squeeze the follower frame 9 to rotate and reset. Then, the sewage can be repeatedly moved, the contact area between the sewage and the ozone is increased, the fusion of the sewage and the ozone is accelerated, and the efficiency of the ozone disinfection work is further improved.

[0029] like Figure 3 As shown, the middle axis position of the linkage frame 6 is installed with a driving shaft 11 that can rotate synchronously therewith, one of the driving shafts 11 is rotatably installed on the side wall of the contact pool 1, and the end of the other driving shaft 11 extends to the outside of the contact pool 1 and is connected with a linkage gear 12 that can rotate synchronously therewith, and the linkage gear 12 is meshed and connected with a driving gear 13. When the driving gear 13 rotates, it can mesh with the linkage gear 12 and rotate synchronously to achieve the purpose of controlling the rotation of the driving shaft 11 and the linkage frame 6. The middle axis position of the driving gear 13 is installed with a driving motor 14 that is compatible with it, and the driving motor 14 can provide power for the operation of the driving gear 13.

[0030] like Figure 2As shown, the side wall of the contact tank 1 is embedded with a water outlet pipe 15 which is connected with the inner cavity thereof, and the water outlet pipe 15 is located above the catalytic packing layer 5. After the sewage contacts with ozone, it rises to a certain height, passes through the catalytic packing layer 5, and after being purified by the catalytic packing layer 5, the oxidized water can be discharged from the contact tank 1 through the water outlet pipe 15 for further purification treatment.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
