[0002] Ozone has strong oxidizing power and is widely used in sterilization, disinfection, deodorization, fading, and removal of iron and manganese. However, ozone gas needs to be treated after use to avoid harm to the environment and human health. Therefore, ozone exhaust gas decomposition devices are required to be installed at the outlet of ozone gas concentration analyzers.

[0003] However, most existing ozone exhaust gas decomposition devices are cylindrical structures, resulting in a short ozone gas flow path, poor catalytic reduction effect, and short device lifespan. There is an urgent need for an ozone exhaust gas decomposition device with gas deflection function to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide an ozone tail gas decomposition device with a gas deflection function to solve the problems mentioned in the background art. This invention improves catalytic reduction efficiency and extends the service life of the device by extending the flow path of ozone gas.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an ozone exhaust gas decomposition device with gas deflection function, comprising an inlet / outlet sealing plate, a stainless steel filter screen, a glass fiber filter sheet, a double-cavity rectangular profile, a blind plate sealing plate, and a sealing plate. Two sealing plates are provided: the left sealing plate is the inlet / outlet sealing plate, and the right sealing plate is the blind plate sealing plate. The double-cavity rectangular profile is sealed and fixed between the inlet / outlet sealing plate and the blind plate sealing plate by a soft PTFE sealing gasket. Two stainless steel filter screens are provided at the left-side connection between the inlet / outlet sealing plate and the double-cavity rectangular profile, and glass fiber filter sheets are laminated to the right end faces of the two stainless steel filter screens.

[0006] Furthermore, the double-cavity rectangular profile is filled with an ozone catalyst.

[0007] Furthermore, a double-cavity air vent is provided at the right end of the interior of the double-cavity rectangular profile.

[0008] Furthermore, multiple locking screw holes are provided at the left end of the air inlet / outlet sealing plate and the right end of the blind plate sealing plate. Locking screws are inserted into the multiple locking screw holes, and the threaded ends of the multiple locking screws are respectively fixed to the left and right sides of the double-cavity rectangular profile through threaded connection.

[0009] Furthermore, the upper and lower sides of the left end of the air inlet and outlet sealing plate are respectively provided with an ozone outlet and an ozone inlet.

[0010] Furthermore, an ozone outlet pipe and an ozone inlet pipe are respectively installed through the ozone outlet and the ozone inlet, and the ozone outlet pipe and the ozone inlet pipe are respectively attached to the left side of the two stainless steel filter screens.

[0011] The beneficial effects of this utility model are as follows: This utility model provides an ozone tail gas decomposition device with gas baffle function. Because it incorporates an ozone inlet pipe, an ozone outlet pipe, inlet and outlet sealing plates, a stainless steel filter screen, a glass fiber filter sheet, a double-cavity rectangular profile, an ozone catalyst, a double-cavity air guide hole, a blind plate sealing plate, a sealing plate, and a soft PTFE sealing gasket, our design improvements and practical use have shown that this device, built into an online ozone concentration analyzer, is used for the decomposition and catalysis of ozone tail gas. Through the double-cavity rectangular profile structure and gas baffle design, the flow path of ozone gas is extended, improving the catalytic reduction efficiency and extending the device's service life. After passing through the ozone tail gas decomposition device, the ozone gas is reduced to oxygen, and then the ozone-free gas can be directly emitted into the atmosphere. The device has a simple structure, is easy to install and maintain, and is suitable for various online ozone concentration analyzers. Attached Figure Description

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-3 This utility model provides a technical solution: an ozone exhaust gas decomposition device with gas deflection function, including an inlet / outlet sealing plate 3, a stainless steel filter screen 4, a glass fiber filter sheet 5, a double-cavity rectangular profile 6, a blind plate sealing plate 9, and a sealing plate 12. Two sealing plates 12 are provided: the left sealing plate 12 is the inlet / outlet sealing plate 3, and the right sealing plate 12 is the blind plate sealing plate 9. The double-cavity rectangular profile 6 is sealed and fixed between the inlet / outlet sealing plate 3 and the blind plate sealing plate 9 by a soft PTFE sealing gasket 13. Two stainless steel filter screens 4 are provided at the left connection point inside the inlet / outlet sealing plate 3 and the double-cavity rectangular profile 6. A glass fiber filter sheet 5 is composited on the right end face of the two stainless steel filter screens 4. This design solves the problem that existing ozone exhaust gas decomposition devices are mostly cylindrical structures, resulting in a short ozone gas flow path, poor catalytic reduction effect, and short device lifespan.

[0019] As the first embodiment of this utility model: the double-cavity rectangular profile 6 is filled with an ozone catalyst 7, which is a reducing agent that reduces ozone gas to ozone-free form.

[0020] The double-cavity rectangular profile 6 has a double-cavity air guide hole 8 at the right end. By adding the double-cavity air guide hole 8, the ozone gas can increase the flow distance inside the double-cavity rectangular profile 6, making ozone catalysis and reduction more effective and extending its service life.

[0021] Multiple locking screw holes 14 are provided on the left end of the air inlet / outlet sealing plate 3 and the right end of the blind plate sealing plate 9. Locking screws are inserted into the multiple locking screw holes 14. The threaded ends of the multiple locking screws are respectively connected and fixed to the left and right sides of the double-cavity rectangular profile 6 by threads. The addition of locking screws facilitates the installation or disassembly of the air inlet / outlet sealing plate 3, the blind plate sealing plate 9 and the double-cavity rectangular profile 6.

[0022] Ozone outlet 11 and ozone inlet 10 are respectively opened through the upper and lower sides of the left end of the air inlet and outlet sealing plate 3. Ozone outlet pipe 2 and ozone inlet pipe 1 are respectively installed through the ozone outlet 11 and ozone inlet 10. The ozone outlet pipe 2 and ozone inlet pipe 1 are respectively attached to the left side of two stainless steel filter screens 4. The addition of two stainless steel filter screens 4 and two glass fiber filter sheets 5 can prevent the powder generated by the ozone catalyst 7 from overflowing after long-term use.

[0023] As a second embodiment of this utility model: First, the device is installed inside an online ozone concentration analyzer, so that the ozone inlet pipe 1 and the ozone outlet pipe 2 are respectively sealed and connected to the inlet and outlet pipes inside the online ozone concentration analyzer. First, the ozone gas enters the lower end of the double-cavity rectangular profile 6 through the ozone inlet pipe 1, and is transmitted to the upper end of the double-cavity rectangular profile 6 through the double-cavity air guide hole 8. After being catalytically reduced by the ozone catalyst 7, it is discharged from the ozone outlet pipe 2. During this process, the two stainless steel filter screens 4 and the two glass fiber filter sheets 5 can prevent the powder generated by the ozone catalyst 7 from overflowing after long-term use. The blind plate sealing plate 9 is used to seal the right side of the double-cavity rectangular profile 6 to ensure that the gas flows inside the double-cavity rectangular profile 6.
