Description

Technical Field

[0001] The utility model relates to the technical field of reaction towers, in particular to a gas-liquid double-circulation ozone catalytic reaction tower. Background Art

[0002] The ozone catalytic reaction tower is a highly efficient wastewater treatment equipment that combines ozone oxidation technology and catalysis. It improves the ozone oxidation efficiency and reaction time through a gas-liquid dual circulation method. Ozone and wastewater rise through the catalyst bed and produce a large number of hydroxyl free radicals under the catalytic action. Subsequently, the large molecular refractory pollutants in the wastewater are directly mineralized, thereby completing the reaction process.

[0003] The existing ozone catalytic reaction tower has the problem that the gas is difficult to disperse during the ozone rising process;

[0004] The reason for this problem is that during the use of the ozone catalytic reaction tower, ozone and wastewater need to be poured into the reaction tower. At this time, a flow trend from bottom to top will be formed inside the reaction tower, causing ozone and wastewater to flow upward from the bottom of the reaction tower. However, the aerators used for ozone injection into the reaction towers of some small and medium-sized reaction towers are limited in size. After entering the reaction tower, ozone will move directly upward with the water flow, resulting in uneven distribution of ozone inside the reaction tower. The wastewater inlet pipe is set below the aerator, and the gas rising speed is greater than the upward flow speed of the wastewater. This results in a low mixing rate of ozone gas with the newly injected wastewater before entering the ozone catalytic device, thereby reducing the utilization rate of ozone gas and affecting the reaction effect inside the reaction tower. Therefore, we propose a gas-liquid dual-circulation ozone catalytic reaction tower. Utility Model Content

[0007] (2) Technical solution

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions: a gas-liquid dual-circulation ozone catalytic reaction tower, comprising a reaction tower body, a microporous aerator is arranged inside the reaction tower body, a mixing mechanism is arranged above the microporous aerator, the mixing mechanism includes a mixing microporous plate, which is rotatably arranged inside the reaction tower body, the mixing microporous plate is used to increase the gas dispersion effect, a support frame is arranged inside the reaction tower body, the support frame is used to support the mixing microporous plate, a stirring plate is rotatably arranged below the support frame, and the stirring plate is used to increase water flow mixing.

[0013] Preferably, the outside of the mounting block is fixedly connected to an extension plate, the inside of the extension plate is fixedly connected to a support rod, and the stirring plate is movably sleeved on the outside of the support rod.

[0014] The utility model discloses a gas-liquid double-circulation ozone catalytic reaction tower, which has the following beneficial effects:

[0015] The gas-liquid dual-circulation ozone catalytic reaction tower moves upward through wastewater and ozone gas. At this time, the flow force generated by the upward movement of ozone and wastewater will drive the stirring plate to rotate. During the rotation of the stirring plate, the gas will diffuse inside the reaction tower, thereby dispersing the gas inside the reaction tower body. Then, when the gas moves upward, it will move to the position of the mixing microporous plate. The flow trend generated by the upward movement of gas and wastewater will cause the mixing microporous plate to rotate. There are multiple groups of micropores inside the mixing microporous plate, which can allow the gas to pass through the micropores to increase the gas dispersion effect and reduce the upward movement speed of the gas. The rotation of the mixing microporous plate can increase the mixing effect of the gas and the wastewater. The rotation of the stirring plate can increase the distribution area of ​​the ozone gas inside the reaction tower body. Then, the rotation of the mixing microporous plate can reduce the upward flow speed of the gas, and the micropores outside the mixing microporous plate can disperse the gas again. The rotation of the mixing microporous plate can increase the mixing effect of ozone and wastewater, thereby increasing the full utilization effect of the ozone gas and improving the utilization efficiency of the ozone catalytic device.

[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. 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 any creative efforts are within the scope of protection of the present invention.

[0024] The embodiment of the present application solves the problem that gas is difficult to disperse during the rising process of ozone in the existing ozone catalytic reaction tower by providing a gas-liquid dual-circulation ozone catalytic reaction tower.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] According to the attached Figure 1-5 As shown, it includes a reaction tower body 1, which can refer to a small ozone catalytic reaction tower with a model of HZYCY-03. A microporous aerator 101 is arranged inside the reaction tower body 1, and a mixing mechanism is arranged above the microporous aerator 101. The mixing mechanism includes a mixing microporous plate 2, which is rotatably arranged inside the reaction tower body 1. The mixing microporous plate 2 is used to increase the gas dispersion effect. A support frame 201 is arranged inside the reaction tower body 1, and the support frame 201 is used to support the mixing microporous plate 2. A stirring plate 202 is rotatably arranged below the support frame 201, and the stirring plate 202 is used to increase water flow mixing.

[0027] A wastewater inlet pipe 103 is provided inside the reaction tower body 1, and the microporous aerator 101 is arranged above the wastewater inlet pipe 103. An ozone catalytic device 102 is provided inside the reaction tower body 1, and the ozone catalytic device 102 is arranged above the mixing microporous plate 2. A support plate 203 is fixedly connected to the inner side of the support frame 201, and a mounting block 206 is fixedly connected to the end of the support plate 203.

[0028] The interior of the mounting block 206 is rotatably connected to a rotating member 207, the mixing microporous plate 2 is movably sleeved on the outside of the rotating member 207, the mixing microporous plate 2 is arranged above the mounting block 206, the outside of the mounting block 206 is fixedly connected to an extension plate 205, the interior of the extension plate 205 is fixedly connected to a support rod 204, and the stirring plate 202 is movably sleeved on the outside of the support rod 204.

[0029] The ozone oxidation efficiency and reaction time are improved through the gas-liquid dual circulation method. Ozone and wastewater rise through the catalyst bed, generating a large number of hydroxyl free radicals under the catalytic action, and then directly mineralize the large molecular difficult-to-degrade pollutants in the wastewater, thus completing the reaction process.

[0030] Ozone gas and wastewater are poured into the interior of the reaction tower body 1 through the microporous aerator 101 and the wastewater inlet pipe 103. At this time, the wastewater and ozone gas will move upward, and a flow trend from bottom to top will be formed inside the reaction tower body 1. At this time, the flow force generated by the upward movement of ozone and wastewater will drive the stirring plate 202 to rotate. At this time, the stirring plate 202 will rotate outside the support rod 204. During the rotation process, the stirring plate 202 will cause the gas to diffuse inside the reaction tower, thereby dispersing the gas inside the reaction tower body 1. Then, when the gas moves upward, it will move to the position of the mixing microporous plate 2. The flow trend generated by the upward movement of the gas and wastewater will cause the mixing microporous plate 2 to rotate. At this time, the mixing microporous plate 2 will rotate outside the rotating part 207. Multiple groups of micropores are arranged inside the mixing microporous plate 2, which can allow the gas to pass through the micropores to increase the gas dispersion effect, and at the same time reduce the upward movement speed of the gas. The rotation of the mixing microporous plate 2 can increase the mixing effect of the gas and the wastewater. By arranging the stirring plate 202 and the mixing microporous plate 2 above the microporous aerator 101, the rotation of the stirring plate 202 can increase the distribution area of ​​the ozone gas inside the reaction tower body 1. Subsequently, the rotation of the mixing microporous plate 2 can reduce the upward flow speed of the gas, and the micropores outside the mixing microporous plate 2 can disperse the gas again, and the rotation of the mixing microporous plate 2 can increase the mixing effect of ozone and wastewater.

[0031] The extension plate 205 and the support rod 204 support the stirring plate 202, so that the stirring plate 202 can be distributed and installed below the mixing microporous plate 2, thereby increasing the distribution effect of the ozone gas. The support frame 201 is used to support the mixing microporous plate 2, thereby increasing the stability of the mixing microporous plate 2 during use.

[0032] In summary, compared with the existing technology, it has the following beneficial effects:

[0033] The wastewater and ozone gas will move upward. At this time, the flow force generated by the upward movement of ozone and wastewater will drive the stirring plate 202 to rotate. During the rotation process, the stirring plate 202 will diffuse the gas inside the reaction tower, thereby dispersing the gas inside the reaction tower body 1. Then, when the gas moves upward, it will move to the position of the mixing microporous plate 2. The flow trend generated by the upward movement of the gas and wastewater will cause the mixing microporous plate 2 to rotate. There are multiple groups of micropores inside the mixing microporous plate 2, which can allow the gas to pass through the micropores to increase the gas dispersion effect and reduce the upward movement speed of the gas. The rotation of the mixing microporous plate 2 can increase the mixing effect of the gas and the wastewater. The rotation of the stirring plate 202 can increase the distribution area of ​​the ozone gas inside the reaction tower body 1. Then, the rotation of the mixing microporous plate 2 can reduce the upward flow speed of the gas, and the micropores on the outside of the mixing microporous plate 2 can disperse the gas again. The rotation of the mixing microporous plate 2 can increase the mixing effect of ozone and wastewater, thereby increasing the full utilization effect of the ozone gas and increasing the utilization efficiency of the ozone catalytic device 102.
