Description

Technical Field

[0001] This utility model relates to an ozone generator exhaust gas destruction device. Background Technology

[0002] Ozone oxidation is a common treatment process in the wastewater and water purification industries. In this process, ozone is mainly used to disinfect and sterilize wastewater and to oxidize and remove organic matter.

[0003] Currently, some wastewater treatment plants use the “MBR (Membrane Bio-Reactor) + Reverse Osmosis (RO) + Ozone Catalytic Oxidation” treatment process. After the ozone catalytic reaction, a certain amount of O3 will remain. If the exhaust gas is directly discharged into the air, it will cause great pollution to the environment. Therefore, exhaust gas destruction devices are installed after the ozone reaction tank to remove the residual O3 in the exhaust gas.

[0004] In the production practice of some projects, it was found that due to large temperature differences on site or catalyst failure, the ozone destruction and removal efficiency of the exhaust gas destroyer will decrease, and the exhaust gas emissions will not meet the standards. Since the exhaust gas destruction device generally does not have a backup, and the equipment maintenance of the exhaust gas destroyer requires a certain amount of time, the sewage treatment system can only be shut down during this period, which affects the timely treatment of sewage.

[0005] When a wastewater treatment plant adopts the "MBR + reverse osmosis (RO) + ozone catalytic oxidation" treatment process, due to the daily maintenance of the entire treatment system, a large number of UPVC pipes, valves, pipe joints, bag filter bags, activated carbon and other materials are often replaced or left idle on site. Utility Model Content

[0006] To address the malfunction of ozone exhaust gas destruction equipment and ensure that ozone exhaust gas emissions meet standards, this utility model aims to fully utilize on-site waste materials. The technical problem it seeks to solve is to utilize a large amount of idle waste pipes, valves, activated carbon, etc., from sewage treatment plants to create a device for emergency treatment of residual O3 in exhaust gas. This device serves as an emergency response mechanism for handling ozone exhaust gas destruction equipment malfunctions, thereby ensuring timely treatment of sewage.

[0007] The technical solution adopted by this utility model to solve its technical problem is: an emergency device for the destruction of ozone generator exhaust gas, comprising:

[0008] The main body of the emergency device is formed by sealing one end of a UPVC pipe with a cap, while the other end is open as an exhaust outlet. A condensate drain pipe is connected to the bottom of the main body.

[0009] The gas distribution device is located inside the main body of the emergency device and is supported by the cover. The gas distribution device is composed of a UPVC pipe with a diameter smaller than that of the main body, which is divided into a support pipe section and a gas distribution pipe section. Each support pipe section is arranged parallel to the axis of the main body, and each gas distribution pipe section is arranged on the cross-section of the main body and connected to each support pipe section through a pipe joint. The gas distribution device is equipped with an exhaust gas inlet pipe at the air inlet end.

[0010] The perforated plate, located inside the body, is supported by the air distribution device, and the outer diameter of the perforated plate is adapted to the inner diameter of the body.

[0011] The filtration device consists of a filter cloth layer laid on the perforated plate and an activated carbon filter layer laid on top of the filter cloth layer.

[0012] Furthermore, an online ozone monitoring and alarm device is installed between the top surface of the activated carbon filter layer and the exhaust outlet.

[0013] Furthermore, an intake valve and a pressure gauge are sequentially installed on the exhaust gas intake pipe along the direction of the airflow.

[0014] The filter cloth layer can be formed by laying the filter bags of a waste bag filter flat.

[0015] The beneficial effects of this invention are: the device can utilize waste, is simple to process, and can quickly adsorb residual ozone in ozone-containing exhaust gas before emission, which is conducive to environmental protection and sustainable production. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the ozone generator exhaust gas destruction emergency device of this utility model includes the main body 1 of the emergency device, the gas distribution device 10, the perforated plate 12, the filter device, etc.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the main body 1 of the emergency device is formed by sealing one end of a UPVC pipe with a cap 11, and the other end is open as a tail gas emission port 13. The purpose is to use the idle UPVC pipe of the sewage treatment plant as the tank of the tail gas destruction emergency device. The tank is used to arrange activated carbon to adsorb O3 in the tail gas to reduce the ozone concentration in the tail gas. The diameter and length of the UPVC pipe used are determined according to the residual O3 concentration and tail gas volume. The cap 11 is sealed to one end of the UPVC pipe. The bottom of the main body 1 is connected to a condensate drain pipe 8. The condensate drain pipe 8 is located outside the main body 1 and is equipped with a drain valve 7 for the discharge of tail gas condensate to ensure that the activated carbon is dry.

[0025] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the gas distribution device 10 is located inside the main body 1 and is supported by the end cap 11. The gas distribution device 10 is composed of a UPVC pipe with a diameter smaller than that of the main body, divided into a support pipe section 101 and a gas distribution pipe section 102. The gas distribution pipe sections 102 are arranged in a ribbed shape. Each support pipe section 101 is arranged parallel to the axial direction of the main body 1, and each gas distribution pipe section 102 is arranged on the cross-section of the main body 1 and connected to a pipe joint 103. Figure 4 , Figure 5(Only the location of the pipe joint is shown in the diagram, and the pipe joint is simplified.) The pipe joints are connected to each supporting pipe section 101. The air inlet end of the air distribution device 10 is equipped with a tail gas inlet pipe 4, which passes through the side wall of the main body 1 and connects to the internal air distribution device 10. On the outside of the main body 1, an inlet valve 5 and a pressure gauge 6 are sequentially installed on the tail gas inlet pipe 4 along the airflow direction. The inlet valve 5 is used to adjust the tail gas intake volume, and the pressure gauge 6 facilitates observation and pressure adjustment, preventing pressure buildup in the front-end suction fan. On one hand, the air distribution device 10 can serve as a support for the orifice plate, providing installation space for the tail gas inlet pipe. Furthermore, the supporting pipe section 101 and the air distribution pipe section 102 are connected by pipe joints to form a three-dimensional pipe frame structure, which can better bear the force and ensure more stable support for the activated carbon. On the other hand, the air distribution device 10 allows the tail gas to enter the filter device above it more evenly, improving the utilization efficiency of the activated carbon. It is also recommended that the air distribution device 10 be made from small-diameter waste UPVC pipes.

[0026] like Figure 1 As shown, the perforated plate 12 is located inside the body 1 and is supported by the air distribution device 10. The outer diameter of the perforated plate 12 is adapted to the inner diameter of the body 1. The main function of the perforated plate 12 is to provide uniform and stable support for the filtration device. The size and opening ratio of its openings do not need to be particularly strict, and the openings can be basically uniform.

[0027] like Figure 1 and Figure 2 As shown, the filtration device is used to adsorb O3 contained in the exhaust gas to reduce the O3 concentration to below the emission standard. Considering waste utilization, the filtration device consists of a filter cloth layer 3 laid on the perforated plate 12 and an activated carbon filter layer 2 laid on the filter cloth layer 3. The activated carbon filter layer 2 is formed by spreading activated carbon on the filter cloth layer 3 and accumulating it along the inner wall of the body 1 to a certain height. The accumulation height of the activated carbon pile is determined according to the exhaust gas emission rate and the residual O3 concentration. The filter cloth layer 3 is formed by laying the filter bag of the waste bag filter flat. Its function is to allow the exhaust gas to pass through and prevent the activated carbon from falling out of the holes of the perforated plate.

[0028] In addition, an ozone concentration monitoring alarm 9 is installed between the top surface of the activated carbon filter layer and the exhaust outlet to monitor the O3 content in the emitted exhaust gas. When the O3 content exceeds the standard, an alarm signal is issued, which helps ensure that exhaust emissions meet standards. The ozone concentration monitoring alarm 9 is a commercially available device.

[0029] This device can utilize waste, is simple to process, and can quickly adsorb residual ozone in ozone-containing exhaust gas before emission. It is mainly used temporarily when repairing exhaust gas destruction devices, which is beneficial to environmental protection and sustainable production.
