[0002] With the rapid development of my country's economy, environmental pollution has become increasingly prominent. Traditional energy consumption is large, and pollutant emissions are still the biggest problem. Prominent environmental problems have seriously restricted my country's economic sustainable development, so environmental governance issues have received attention from various departments.

[0003] In the prior art, in order to improve the efficiency of wastewater treatment so that the discharge meets the national emission standards, researchers in this field have invented many methods to improve the wastewater treatment capacity. Ozone catalytic oxidation technology is an efficient wastewater deep treatment technology. Compared with other deep treatment technologies, ozone catalytic oxidation technology is more mature and has better treatment effects. Its principle is that the catalyst catalyzes ozone to generate strong oxidizing hydroxyl free radicals. Hydroxyl free radicals have extremely strong oxidizing properties and can oxidize and decompose large molecular organic pollutants in wastewater that are difficult to biodegrade into small molecular organic matter that is easy to biodegrade, or directly oxidize and decompose into water and carbon dioxide, so the treatment effect is obvious. However, existing ozone catalytic oxidation devices generally have the problems of low ozone utilization and poor wastewater treatment effect.

[0004] Therefore, a three-dimensional device of a catalytic oxidation reactor is needed to solve the problems of low ozone utilization rate and poor wastewater treatment effect existing in the prior art. Utility Model Content

[0007] The catalytic oxidation reaction mechanism comprises a reaction box, a bed plate is fixedly connected to the upper middle part of the reaction box, and a placement groove is provided on the top surface of the bed plate.

[0008] It should be noted in the scheme that a microwave generator is fixedly installed on the front of the reaction box, and a radiation head is symmetrically fixedly connected to the inside of the reaction box. The microwave generator is electrically connected to the radiation head, and the radiation heads are of different lengths and arranged in a matrix.

[0009] It is further worth mentioning that the filtering mechanism comprises a fixed frame, a filter screen is symmetrically arranged inside the fixed frame, a mounting block is fixedly connected to the front end of the filter screen, and a push-pull plate is fixedly connected to the front side of the mounting block.

[0010] It should be further explained that a hole matching with the mounting block is provided on the front of the fixing frame, and a sealing layer is provided at the position where the mounting block is connected with the hole.

[0011] As a preferred embodiment, positioning grooves are symmetrically opened on the upper and lower sides of the mounting block, and mounting grooves are symmetrically opened on both sides of the hole of the fixed frame. A spring is fixedly connected inside the mounting groove, and a positioning column is fixedly connected to the other end of the spring, and the positioning column is slidably connected to the mounting groove.

[0012] As a preferred implementation, the size of the positioning column is adapted to the positioning slot, and one end of the positioning column close to the positioning slot is configured to be in a truncated cone shape.

[0013] Compared with the prior art, the three-dimensional device of the catalytic oxidation reactor provided by the utility model has at least the following beneficial effects:

[0014] (1) A catalytic oxidation reaction mechanism is set up, in which multiple radiation heads of different lengths are arranged in a matrix, which meets the microwave radiation requirements at different angles, optimizes the distribution and penetration depth of microwave energy, stimulates the activity of the catalyst, and allows ozone to react with wastewater, thereby increasing the utilization rate of ozone, improving the efficiency of the catalytic oxidation reaction and the wastewater treatment effect.

DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with the embodiments.

[0023] See also Figure 1-5 The utility model provides a three-dimensional device of a catalytic oxidation reactor, including a pipeline 1, a filter mechanism 2 is connected to the end of the pipeline 1, the other side of the filter mechanism 2 is connected to a catalytic oxidation reaction mechanism 4 through the pipeline 1, and an ozone generator 3 is connected between the filter mechanism 2 and the catalytic oxidation reaction mechanism 4 through the pipeline 1.

[0024] The catalytic oxidation reaction mechanism 4 comprises a reaction box 401 , a bed plate 402 is fixedly connected to the upper middle part of the reaction box 401 , and a placement groove 403 is provided on the top surface of the bed plate 402 .

[0025] Further as Figure 1 , Figure 4 and Figure 5 As shown, it is worth to explain in detail that a microwave generator 404 is fixedly installed on the front of the reaction box 401, and a radiation head 405 is symmetrically fixedly connected inside the reaction box 401, the microwave generator 404 is electrically connected to the radiation head 405, and the radiation heads 405 are of different lengths and arranged in a matrix;

[0026] The radiation head 405 is provided to meet the microwave radiation requirements at different angles, optimize the distribution and penetration depth of microwave energy, stimulate the activity of the catalyst, and make ozone react with wastewater, thereby accelerating the wastewater treatment efficiency and improving the efficiency and quality of the catalytic oxidation reaction. The catalyst is excited by microwaves, and ozone is decomposed on the catalyst surface to produce oxygen atoms, which react with adsorbed organic matter. The method can increase the efficiency of the microwave catalytic oxidation wastewater treatment system, reduce the reaction energy consumption, and improve the utilization rate of ozone.

[0027] According to the above working process, it can be known that: by setting up the catalytic oxidation reaction mechanism 4, in which the multiple radiation heads 405 are of different lengths and arranged in a matrix, the microwave radiation requirements at different angles are met, the distribution and penetration depth of microwave energy are optimized, the activity of the catalyst is stimulated, and ozone reacts with wastewater, thereby increasing the utilization rate of ozone, and improving the efficiency of the catalytic oxidation reaction and the wastewater treatment effect.

[0028] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth to explain in detail that the filter mechanism 2 includes a fixed frame 201, and a filter screen 202 is symmetrically arranged inside the fixed frame 201, and a mounting block 203 is fixedly connected to the front end of the filter screen 202, and a push-pull plate 204 is fixedly connected to the front of the mounting block 203;

[0029] The push-pull plate 204 is provided to facilitate pulling and pulling of the filter screen 202, and the filter screen 202 can be disassembled and assembled, thereby improving the practicability of the device.

[0030] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth to explain in detail that a hole matching with the mounting block 203 is opened on the front of the fixing frame 201, and a sealing layer 205 is provided at the position where the mounting block 203 is connected with the hole;

[0031] The sealing layer 205 can ensure the sealing of the filter mechanism 2, avoid leakage of waste water, and improve the practicability of the device.

[0032] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth specifically explaining that positioning grooves 206 are symmetrically opened on the upper and lower sides of the mounting block 203, and mounting grooves are symmetrically opened on both sides of the hole of the fixing frame 201. A spring 207 is fixedly connected inside the mounting groove, and a positioning column 208 is fixedly connected to the other end of the spring 207. The positioning column 208 is slidably connected to the mounting groove. The size of the positioning column 208 is adapted to the positioning groove 206, and the end of the positioning column 208 close to the positioning groove 206 is set to a truncated cone shape;

[0033] When the positioning column 208 is inserted into the positioning groove 206, the position of the mounting block 203 can be fixed to ensure the filtering stability of the filter 202. When the filter 202 needs to be pulled out, the push-pull plate 204 is pulled outward with force, and the positioning groove 206 can push the truncated cone-shaped positioning column 208 to contract the spring 207 and retract the positioning column 208 into the mounting groove, thereby releasing the positioning of the mounting block 203 and allowing the filter 202 to be pulled out.

[0034] This solution has the following working process: when in use, wastewater first enters the interior of the fixed frame 201 through the pipeline 1, and impurities in the wastewater can be filtered through the double filter 202. The filtered wastewater is then transmitted through the pipeline 1. At the same time, the ozone generated by the ozone generator 3 is mixed with the wastewater in the pipeline 1, and the mixed gas is transmitted to the interior of the reaction box 401. The microwave generator 404 is controlled to evenly distribute microwave energy inside the reactor through the radiation head 405. The catalyst inside the placement tank 403 is excited by microwaves to stimulate the activity of the catalyst, so that the ozone reacts with the wastewater, thereby accelerating the treatment efficiency of the wastewater, and the treated gas is then output through the pipeline 1.

[0035] In summary: by setting up the catalytic oxidation reaction mechanism 4, in which the multiple radiation heads 405 are of different lengths and arranged in a matrix, the microwave radiation requirements at different angles are met, the distribution and penetration depth of microwave energy are optimized, the activity of the catalyst is stimulated, and ozone reacts with wastewater, thereby increasing the utilization rate of ozone, improving the efficiency of the catalytic oxidation reaction and the wastewater treatment effect; by setting up the filtering mechanism 2, the impurities generated in the wastewater can be filtered through the filter net 202 in advance, and the filter net 202 can be pulled out for cleaning after long-term use to prevent impurities from clogging the filter net 202, thereby improving the subsequent treatment effect of the wastewater and improving the usability of the device.
