[0031] Refer to Figure 1 , Figure 1The sectional view of an ozone catalytic oxidation reactor provided by an embodiment of the present utility model. An ozone catalytic oxidation reactor provided by an embodiment of the present utility model includes a reaction cylinder 100, a catalytic assembly 200, and a water distributor 300; a receiving cavity 110 is provided inside the reaction cylinder 100, and a water inlet 120 and a water outlet 130 communicating with the receiving cavity 110 are respectively provided at both ends of the reaction cylinder 100; the catalytic assembly 200 is disposed in the receiving cavity 110 and is located between the water inlet 120 and the water outlet 130; at least a part of the water distributor 300 is received in the receiving cavity 110 and is connected to the reaction cylinder 100. A first water distribution channel 310 and a second water distribution channel 320 are provided on the water distributor 300. The second water distribution channel 320 is arranged in a ring around the first water distribution channel 310, and in the flowing direction of the ozone water, the inner diameter of the first water distribution channel 310 gradually expands; the two ends of the second water distribution channel 320 and the first water distribution channel 310 are respectively opposite to the water inlet 120 and the catalytic assembly 200, so that the ozone water entering through the water inlet 120 enters the catalytic assembly 200 through the first water distribution channel 310 and the second water distribution channel 320.

[0032] Specifically, for the ozone water entering through the water inlet 120 in this application, a part of it is distributed to the middle area on the side of the catalytic assembly 200 away from the water outlet 130 in a diffused manner through the first water distribution channel 310, and another part is distributed in a ring to the edge area on the side of the catalytic assembly 200 away from the water outlet 130 through the second water distribution channel 320, so that the ozone water is evenly distributed on one side of the catalytic assembly 200, thereby ensuring that the ozone water can fully contact the catalytic assembly 200, improving the utilization rate of ozone or the catalytic assembly 200, and improving the treatment efficiency of the ozone catalytic oxidation reactor.

[0033] It should be noted that on the side of the catalytic assembly 200 away from the water outlet 130, it is divided into a middle area and an edge area. The edge area is continuous with the middle area and is arranged in a ring around the middle area. The middle area is the area of the catalytic assembly 200 close to the center position, and the edge area is the area of the catalytic assembly 200 far from the center position.

[0034] Refer to Figure 1 、 Figure 2 and Figure 3 , Figure 2 The sectional view of the water distributor in the ozone catalytic oxidation reactor provided by an embodiment of the present utility model. Figure 3 The top view of the water distributor of the ozone catalytic oxidation reactor provided by an embodiment of the present utility model. In one embodiment, the water distributor 300 includes a water isolation plate 330 and a distribution plate 340. The water isolation plate 330 is annular, the inner side of the water isolation plate 330 is connected to the distribution plate 340, the first water distribution channel 310 is arranged on the distribution plate 340, and the second water distribution channel 320 is arranged on the water isolation plate 330.

[0035] Specifically, the water baffle 330 and the distribution plate 340 are arranged in the accommodating chamber 110, and the water baffle 330 and the distribution plate 340 are arranged opposite to the water inlet 120. A part of the ozone water entering through the water inlet 120 flows into the first water distribution channel 310, and the other part will be blocked by the water baffle 330, and then flow into the second water distribution channel 320 along the water baffle 330, that is, the present application separates the ozone water entering through the water inlet 120 through the arrangement of the water baffle 330 and the distribution plate 340, so that the ozone water is evenly distributed on the side of the catalyst component 200 away from the water outlet 130, thereby improving the utilization rate of ozone or the catalyst component 200 and improving the processing efficiency of the ozone catalytic oxidation reactor.

[0036] It should be noted that there is a certain distance between the distribution plate 340 and the catalyst assembly 200, so as to ensure that the ozone water flowing out through the second water distribution channel 320 can diffuse to the catalyst assembly 200 to cover more areas on one side of the catalyst assembly 200 and improve the uniformity of water distribution.

[0037] Furthermore, the first water distribution channel 310 includes a first opening 311 and a second opening 312. The first opening 311 is located at one end close to the water inlet 120. In the direction from the first opening 311 to the second opening 312, the inner diameter of the first water distribution channel 310 gradually expands. The water baffle 330 is connected to the end of the distribution plate 340 close to the first opening 311, thereby avoiding the formation of an angle area at the connection between the water baffle 330 and the distribution plate 340, thereby improving the smoothness of the flow of ozone water.

[0038] See also Figure 1 , Figure 2 and Figure 3 In one embodiment, there is a preset gap between the outer side of the water-blocking plate 330 and the cavity wall of the accommodating cavity 110 , and the preset gap is configured to form a second water distribution channel 320 .

[0039] Specifically, the second water distribution channel 320 is located between the outer side of the water baffle 330 and the cavity wall of the accommodating cavity 110, so that the ozone water flowing out through the second water distribution channel 320 can flow along the cavity wall of the accommodating cavity 110 to the edge area of ​​the catalytic assembly 200, that is, the cavity wall on one side of the second water distribution channel 320 can play a guiding role.

[0040] See also Figure 1 , Figure 2 and Figure 3 In one of the embodiments, in the projection of the ozone water flow direction, the projected outer contour of the water baffle 330 is located outside the projected outer contour of the distribution plate 340, thereby reducing the overlap between the ozone water diffused through the first water distribution channel 310 and the ozone water discharged through the second water distribution channel 320, thereby improving the uniformity of water distribution.

[0041] See alsoFigure 1 In one embodiment, the wall of the accommodation chamber 110 includes a first arc-shaped wall 140 that protrudes away from the catalytic assembly 200. The second water distribution channel 320 is located between the water isolation plate 330 and the first arc-shaped wall 140, so that the ozone water flowing out through the second water distribution channel 320 can flow along the first arc-shaped wall 140, improving the smoothness of the ozone water flow. Among them, the water inlet 120 is arranged in the area of the first arc-shaped wall 140 away from the catalytic assembly 200.

[0042] Refer to Figure 1 In one embodiment, the water inlet 120 is located at the lowest point of the reaction cylinder 100, that is, the first arc-shaped wall 140 is arranged on the lower side of the reaction cylinder 100, and the water inlet 120 is arranged in the middle area of the first arc-shaped wall 140, so as to ensure that there is no stagnant water at the bottom of the ozone catalytic oxidation reactor, impurities are not easily deposited, the ozone utilization rate is improved, and the efficiency of the ozone catalytic oxidation reactor is provided.

[0043] Furthermore, the wall of the accommodation chamber 110 further includes a second arc-shaped wall 160 that protrudes away from the catalytic assembly 200, and the second arc-shaped wall 160 is located on the upper side of the reaction cylinder 100, and the water outlet 130 is located at the highest point of the second arc-shaped wall 160. The second arc-shaped wall 160 can play a guiding role, so that the purified wastewater in the edge area of the reaction cylinder 100 can flow along the second arc-shaped wall 160 to the water outlet 130, avoiding the deposition of stagnant water.

[0044] Refer to Figure 1 、 Figure 2 and Figure 3 In one embodiment, a water inlet pipe 150 is provided at one end of the reaction cylinder 100, the water inlet 120 is arranged on the water inlet pipe 150, the ozone catalytic oxidation reactor further includes a mounting seat 350, the mounting seat 350 is connected to the water inlet pipe 150 and is also connected to the water isolation plate 330, and a water inlet hole 351 communicating with the first water distribution channel 310 and the second water distribution channel 320 is provided on the mounting seat 350, and the water inlet hole 351 is used for ozone water to enter.

[0045] Specifically, by connecting the mounting seat 350 to the water inlet pipe 150 and connecting the mounting seat 350 to the water isolation plate 330, the connection between the water distributor 300 and the reaction cylinder 100 is realized. Among them, the water inlet hole 351 can be connected to an external water pipe for transporting ozone water, so that the ozone water entering through the water inlet hole 351 can enter the catalytic assembly 200 through the first water distribution channel 310 and the second water distribution channel 320. Among them, the setting of connecting the mounting seat 350 to the water inlet pipe 150 can facilitate the observation of the water distributor 300 to ensure the connection between the water distributor 300 and the reaction cylinder 100, improving the reliability of the ozone catalytic oxidation reactor. Preferably, the water hole 351 is arranged opposite to the first water distribution channel 310.

[0046] Further, the water blocking plate 330 is located above the water inlet pipe 150, so that the ozone water flowing out through the second water distribution channel 320 can flow along the first arc-shaped wall 140 to accurately reach the edge area of the catalytic assembly 200.

[0047] Refer to Figure 1 、 Figure 2 and Figure 3 In one embodiment, the size of the water inlet hole 351 is smaller than the size of the water inlet 120 and larger than the size of the opening on the side of the first water distribution channel 310 close to the water blocking plate 330.

[0048] Specifically, the size of the first opening 311 is smaller than the sizes of the water inlet 120 and the water inlet hole 351, so that only part of the ozone water entering through the water inlet hole 351 can enter the first water distribution channel 310, thus ensuring that part of the ozone water can enter the second water distribution channel 320 and improving the reliability of the ozone catalytic oxidation reactor. Preferably, the center line of the water inlet hole 351 coincides with the center line of the first water distribution channel 310.

[0049] Refer to Figure 1 、 Figure 2 and Figure 3 In one embodiment, the mounting seat 350 includes a support member 352 and at least two support columns 353. The support member 352 is connected to the water inlet pipe 150, the water inlet hole 351 is arranged on the support member 352, at least two support columns 353 are arranged at intervals in the circumferential direction, and one end of the support column 353 is connected to the support member 352 and the other end is connected to the water blocking plate 330.

[0050] Specifically, the support column 353 extends out of the water inlet pipe 150 and is connected to the water blocking plate 330 to support the water blocking plate 330 and the distribution plate 340. There is a gap between adjacent support columns 353 through which the ozone water entering through the water inlet hole 351 can pass, so that part of the ozone water can flow into the second water distribution channel 320.

[0051] Further, a bending portion 151 is provided at the end of the water inlet pipe 150. The support member 352 is arranged outside the water inlet pipe 150 and connected to the bending portion 151, so as to ensure the stability of the connection between the water distributor 300 and the reaction cylinder 100.

[0052] Further, the support member 352 includes a first flange 354, a second flange 355, and a connecting cylinder 356. The first flange 354 and the second flange 355 are respectively connected to two ends of the connecting cylinder 356. The water inlet hole 351 is provided on the connecting cylinder 356. The first flange 354 is connected to the bent portion 151, and the second flange 355 is connected to the water pipe for conveying ozone water. By arranging the support member 352 outside the water inlet pipe 150 and connecting it to the end of the water inlet pipe 150, the stability of the connection between the water distributor 300 and the reaction cylinder 100 can be ensured.

[0053] Refer to Figure 1 , in one embodiment, the outer contour dimension of the water isolation plate 330 is smaller than the inner contour dimension of the water inlet pipe 150, and the outer contour dimension of the distribution plate 340 is smaller than the outer contour dimension of the water isolation plate 330, so that both the water isolation plate 330 and the distribution plate 340 can enter and exit through the water inlet pipe 150, enabling the water distributor 300 to be conveniently disassembled and installed.

[0054] Refer to Figure 1 and Figure 4 , Figure 4 is a partial top view of the catalytic component in the ozone catalytic oxidation reactor provided by an embodiment of the present utility model. In one embodiment, the catalytic component 200 includes a support plate 210 and a catalyst 220. The support plate 210 is connected to the cavity wall of the accommodation cavity 110 and is located between the water inlet 120 and the water outlet 130. The catalyst 220 is placed on the support plate 210. A plurality of through holes 211 are provided on the support plate 210 at intervals for ozone water to pass through. Preferably, the through holes 211 are evenly spaced.

[0055] Further, the catalytic component 200 further includes a water filtering cap 230, and the water filtering cap 230 is installed in the through hole 211, so as to prevent the catalyst 220 from flowing out through the through hole 211.

[0056] Refer to Figure 1 , in one embodiment, an installation hole 170 is further provided on the cavity wall of the accommodation cavity 110. The installation hole 170 is located on the side of the support plate 210 close to the water outlet 130. The installation hole 170 is used for the catalyst 220 to be moved in or out. A mounting cover 180 is detachably connected to the installation hole 170, and the mounting cover 180 covers the installation hole 170 to prevent the catalyst 220 from moving out.

[0057] Refer to Figure 1 and Figure 4 , in one embodiment, the ozone catalytic oxidation reactor further includes a sieve tube 190. The sieve tube 190 is connected to the reaction cylinder 100 and is located at the water outlet 130, so that the purified wastewater flows out through the sieve tube 190 to prevent the catalyst 220 from being carried out of the ozone catalytic oxidation reactor.

[0058] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the various technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0059] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several variations and improvements can still be made, and these all belong to the protection scope of the present utility model.
