Description

Technical Field

[0001] The utility model relates to the technical field of ozone treatment equipment, in particular to an ozone tail gas destroyer. Background Art

[0002] Ozone is a strong oxidant that can effectively sterilize. Therefore, it is widely used in environmental protection, medical and health care, water treatment, pharmaceuticals, food preparation, cosmetics preparation and other fields that require sterilization or disinfection. Due to its strong oxidizing ability, ozone is often used to remove organic and inorganic pollutants in water during sterilization or disinfection. However, during use, unconsumed ozone becomes ozone waste gas. Ozone has strong oxidizing properties and can cause certain harm to humans, animals and plants. If it is directly discharged, it will cause environmental pollution. Therefore, ozone needs to be destroyed before discharge.

[0003] However, in the existing ozone exhaust destruction equipment, the ozone waste gas is usually input into a high-temperature device for high-temperature destruction before it can be discharged. For example, an ozone exhaust destruction device disclosed in Chinese patent document CN217188863U, the ozone exhaust destruction device is configured to include a double-layer tank body, the outer layer of the tank body is an insulation layer, the inner layer is a destruction layer, two openings are respectively provided at both ends of the tank body, a heating rod extends into the destruction layer along one of the openings, and the other opening corresponding to the heating rod is an exhaust port, and the ozone exhaust inlet extends from the outside of the tank body to the destruction layer and is at the same end of the tank body as the heating rod.

[0004] In the above-mentioned prior art ozone exhaust destruction device, since a large amount of catalyst material needs to be filled in the tank body, it is relatively difficult to disassemble the tank when it needs to be replaced after long-term use. In addition, the inside of the tank body needs to be wrapped with an insulation layer to prevent the surface of the tank body from heating up, which leads to a relatively higher cost for the entire tank body. Utility Model Content

[0005] In order to overcome the defects of the prior art, the utility model provides an ozone tail gas destroyer, aiming to solve the problems in the prior art.

[0006] The technical solution adopted by the utility model to solve the technical problem is: an ozone tail gas destroyer, comprising a cylinder, a heating component is inserted into the cylinder, an air inlet and an air outlet pipe are respectively arranged on the outer wall of one end of the cylinder, an air inlet cavity and an ozone destruction cavity are formed in the cylinder, the air inlet cavity is connected with one end of the ozone destruction cavity, the air inlet cavity is arranged around the outside of the ozone destruction cavity, the heating component is located in the ozone destruction cavity, the air inlet is connected with the air inlet cavity, the ozone destruction cavity is connected with the air outlet pipe, and a catalyst cylinder is installed on the air outlet pipe.

[0007] In the above-mentioned ozone exhaust destructor, the catalyst tube is filled with a manganese-based composite metal oxide catalyst layer, and an exhaust port is arranged at one end of the catalyst tube away from the exhaust pipe.

[0008] In the above-mentioned ozone exhaust destructor, the cylinder body includes an outer cylinder and an inner cylinder, and the outer cylinder and the inner cylinder are not in contact with each other, so that the air inlet cavity is formed between the outer cylinder and the inner cylinder, and the inner wall of the inner cylinder is provided with an air outlet hole, and the air outlet pipe passes through the air inlet cavity and is connected with the air outlet hole. A plurality of connecting holes are provided on the inner wall of the inner cylinder away from the air inlet end, so that the air inlet cavity and the ozone destruction cavity are connected.

[0009] In the above-mentioned ozone tail gas destructor, a mounting flange is installed at the upper end of the cylinder, a mounting base is installed at the lower end, and the heating component is fixed on the mounting flange.

[0010] In the above-mentioned ozone exhaust destructor, a sealing cover is provided at the upper end of the heating component, the sealing cover is provided at the upper end of the ozone destruction chamber, a controller is installed at the upper end of the sealing cover, support plates are installed on both sides of the controller, and the lower end of the support plate is fixedly connected to the mounting flange.

[0011] In the above-mentioned ozone tail gas destructor, the heating component is a heating rod.

[0012] The beneficial effect of the utility model is that ozone waste gas is input into the air inlet cavity through the air inlet, so that the ozone waste gas surrounds the outside of the ozone destruction cavity, and then enters the ozone destruction cavity, so that the ozone waste gas is destroyed by high temperature through the heating component in the ozone destruction cavity, and then the destroyed ozone waste gas is passed into the catalyst cylinder for catalysis, so that the ozone waste gas is completely decomposed and then discharged, and the decomposition efficiency is higher. Moreover, since the ozone waste gas is continuously input into the ozone destruction cavity from the air inlet cavity, the surface temperature of the cylinder is relatively low, the overall structure is relatively simpler, and there is no need to adopt a traditional insulation layer structure. The equipment cost is relatively lower, and it can prevent the surface of the cylinder from becoming hot and causing burns to personnel. At the same time, since the catalyst cylinder is located outside the cylinder, it is more convenient to replace. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0019] Combination Figures 1 to 4 The ozone exhaust destructor shown in the figure comprises a cylinder 1, a heating component 9 is inserted into the cylinder 1, an air inlet 3 and an air outlet pipe 4 are respectively arranged on the outer wall of one end of the cylinder 1, and the cylinder 1 is divided into an air inlet chamber 15 and an ozone destruction chamber 12, the air inlet chamber 15 is connected to one end of the ozone destruction chamber 12, the air inlet chamber 15 is arranged around the outside of the ozone destruction chamber 12, the heating component 9 is located in the ozone destruction chamber 12, the air inlet 3 is connected to the air inlet chamber 15, the ozone destruction chamber 12 is connected to the air outlet pipe 4, and a catalyst cartridge 5 is installed on the air outlet pipe 4; in this embodiment, the ozone exhaust gas is input into the air inlet chamber 15 through the air inlet 3, so that the ozone exhaust gas surrounds the ozone exhaust gas. The ozone waste gas passes through the oxygen destruction chamber 12 and then enters the ozone destruction chamber 12, so that the ozone waste gas is destroyed by high temperature through the heating component 9 in the ozone destruction chamber 12, and then the destroyed ozone waste gas is passed into the catalyst cylinder for catalysis, so that the ozone waste gas is completely decomposed and then discharged, and the decomposition efficiency is higher. Moreover, since the ozone waste gas is continuously input from the air inlet chamber 15 into the ozone destruction chamber 12, the surface temperature of the cylinder 1 is relatively low, the overall structure is relatively simpler, and there is no need to adopt a traditional insulation layer structure. The equipment cost is relatively lower, and it can prevent the surface of the cylinder 1 from becoming hot and causing burns to personnel. At the same time, since the catalyst cylinder 5 is located outside the cylinder 1, it is more convenient to replace.

[0020] It is worth noting that the catalyst cartridge 5 of the present embodiment is filled with a manganese-based composite metal oxide catalyst layer, and an exhaust port 6 is provided at one end of the catalyst cartridge 5 away from the exhaust pipe 4. The ozone decomposed by high temperature is further catalytically decomposed by the manganese-based composite metal oxide catalyst layer, so that the ozone waste gas is completely decomposed and then discharged through the exhaust port 6, thereby preventing the ozone waste gas from polluting the environment. At the same time, since the manganese-based composite metal oxide catalyst layer has an automatic repair function at high temperature, namely high-temperature reduction, the effect of the manganese-based composite metal oxide catalyst layer is more lasting.
