Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of sewage treatment, and in particular relates to an ozone catalytic oxidation device. Background Art
[0002] Ozone catalytic oxidation technology is widely used in advanced wastewater treatment due to its strong oxidation capacity, effective treatment results, fast reaction speed, and low risk of secondary pollution. Ozone catalytic oxidation requires the presence of a catalyst for a more complete reaction, making the catalyst crucial to the process. However, in actual engineering applications, after the catalyst is added to the ozone catalytic oxidation tower, it is inconvenient to remove and install, so it is only replaced during equipment overhauls, typically every three to five years. This limits catalyst updates and increases maintenance costs. Utility Model Content
[0003] Purpose of the utility model: In order to solve the problems existing in the prior art, the utility model provides an ozone catalytic oxidation device with replaceable catalyst fillers to solve the problem of difficulty in replacing the catalyst raised in the above background technology.
[0004] Technical solution: An ozone catalytic oxidation device includes an ozone catalytic oxidation tower and a catalyst layer. The catalyst layer is composed of a plurality of catalyst filler replacement devices, and the catalyst filler replacement devices are installed on the side wall of the ozone catalytic oxidation tower by bolts;
[0005] The bottom air inlet of the ozone catalytic oxidation tower is connected to the ozone generator, and the bottom water outlet is connected to the sewage outlet pipe; the top water inlet of the ozone catalytic oxidation tower is connected to the sewage inlet pipe, and the top air outlet is connected to the ozone destroyer.
[0006] Furthermore, the ozone catalytic oxidation tower is connected to a water pump through a first sewage pipe and a second sewage pipe. The other end of the first sewage pipe is located at the top of the ozone catalytic oxidation tower, and the other end of the second sewage pipe is located at the bottom of the ozone catalytic oxidation tower.
[0007] Furthermore, the bottom of the ozone catalytic oxidation tower is connected to the ozone generator through an ozone inlet pipe, and the top is connected to the ozone destroyer through an ozone outlet pipe.
[0008] Furthermore, the catalyst filling replacement devices are evenly installed around the ozone catalytic oxidation tower, and the structures of the catalyst filling replacement devices are the same; different catalyst fillings are placed in each catalyst filling replacement device.
[0009] Furthermore, the catalyst filler replacement device is a hollow triangular prism structure, the side walls of which are composed of three rectangular porous steel plates, and the triangular porous steel plates at the top and bottom are both removable.
[0010] Furthermore, a sealing strip is provided at the contact point between the catalyst filler replacement device and the side wall of the ozone catalytic oxidation tower.
[0011] The beneficial effects of the utility model are as follows:
[0012] 1. The utility model can add different catalyst fillers in different catalyst filler replacement devices, and replace the type and quantity of catalyst fillers according to different reaction conditions and requirements. It can adapt to various application scenarios and has excellent adaptability and flexibility.
[0013] 2. When replacing the catalyst packing, the utility model only needs to disassemble the second nut on the catalyst packing replacement device to complete the replacement of the catalyst packing, which greatly reduces the manpower and time for replacing the catalyst packing, improves work efficiency, and also reduces production costs, thus achieving convenience and efficiency in replacing the catalyst packing.
[0014] 3. When removing the catalyst filler from the traditional device, it is necessary to open the top cover and fish the catalyst filler out from the top, which poses a risk of high-altitude operation. The device of the utility model can directly remove the catalyst filler replacement device by disassembling the first nut on the side, which greatly reduces the risk of high-altitude operation when replacing the filler. At the same time, it can also ensure that the failed catalyst filler is completely removed, greatly reducing the amount of failed catalyst filler remaining;
[0015] 4. The utility model separates a plurality of catalyst fillers. When a certain catalyst filler fails, it is more convenient to replace the failed catalyst filler, thereby avoiding replacing the catalyst filler with excellent effect and still within the validity period.

DETAILED DESCRIPTION
[0019] The technical solution of the utility model is described in detail below with reference to the accompanying drawings and specific implementation methods.
[0020] Reference Figure 1 、 Figure 2 An ozone catalytic oxidation device with replaceable catalyst fillers includes an ozone catalytic oxidation tower 8 and a catalyst filler replacement device 13.

[0021] The bottom of the ozone catalytic oxidation tower 8 is connected to the ozone generator 6 via the ozone inlet pipe 5 , and the top is connected to the ozone destroyer 11 via the ozone outlet pipe 10 .
[0022] The ozone catalytic oxidation tower 8 is connected to the water pump 1 through the first sewage pipe 2 and the second sewage pipe 3.
[0023] The catalyst filler replacement device 13 is fixed to the side wall of the ozone catalytic oxidation tower 8 via six first nuts 9 .
[0024] The above-mentioned catalyst layer is composed of several catalyst filling replacement devices 13 of exactly the same shape, which are evenly installed around the ozone catalytic oxidation tower 8; different types of catalyst fillings can be placed in each catalyst filling replacement device 13 according to the needs of sewage treatment; when a catalyst filling fails, only the corresponding catalyst filling replacement device needs to be taken out to replace the failed catalyst filling, thereby improving the flexibility of the ozone catalytic oxidation reaction and the maintenance efficiency of the ozone catalytic oxidation tower 8.
[0025] The above-mentioned catalyst filler replacement device 13 consists of three rectangular porous steel plates 17 and two triangular porous steel plates 19. The top and bottom porous steel plates are fixed by three second nuts 15, and the remaining three rectangular porous steel plates 17 are fixed by welding. The rectangular porous steel plates 17 and the triangular porous steel plates 19 are made of stainless steel.
[0026] A sealing strip 16 is installed in the support column groove 18 between the catalyst packing replacement device 13 and the side wall of the ozone catalytic oxidation tower 8. During use, sewage enters the ozone catalytic oxidation tower 8 through the sewage inlet pipe 7. Ozone generated by the ozone generator 6 enters the aeration plate 4 in the ozone catalytic oxidation tower 8 through the ozone inlet pipe 5. After entering the ozone catalytic oxidation tower 8, the sewage and ozone undergo an ozone catalytic oxidation reaction under the action of the catalyst packing. During the reaction, the water pump 1 pumps the sewage through the first sewage pipe 2 to the second sewage pipe 3, and then discharges it back into the ozone catalytic oxidation tower 8, achieving multiple sewage cycle reactions. The sewage after the reaction is discharged to the next sewage treatment unit through the sewage outlet pipe 12. The residual ozone tail gas is discharged through the ozone outlet pipe 10 to the ozone destructor 11 for destruction.
[0027] When replacing the catalyst packing in a certain catalyst packing replacement device 13, first unscrew the first nut 9 on the side wall of the ozone catalytic oxidation tower 8 and take out the catalyst packing replacement device 13; then unscrew the second nut 15 on the catalyst packing replacement device, open the two triangular porous steel plates 19, clean out the expired catalyst packing, and pour new catalyst packing into the catalyst packing replacement device 13; then fix the two triangular porous steel plates 19 on the packing replacement device 13 by tightening the second nut 15, and then install the packing replacement device 13 filled with catalyst packing on the side wall of the ozone catalytic oxidation tower 8 by tightening the first nut 9.
