Description

Technical Field

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

[0002] An ozone generator is a device used to produce ozone gas. Ozone is easily decomposed and cannot be stored. It needs to be produced on-site and used on-site (it can be stored for a short period of time under special circumstances). Therefore, an ozone generator is required in all places where ozone can be used. Ozone generators are widely used in drinking water, sewage, industrial oxidation, food processing and preservation, pharmaceutical synthesis, space sterilization and other fields. The ozone gas produced by the ozone generator can be used directly or mixed with liquid through a mixing device to participate in the reaction.

[0003] Ozone generators are usually used for water treatment in non-pressure water tanks. They dissolve ozone into water through nozzles or bubble diffusers. After the initial treatment, the water can be equipped with a sodium hypochlorite disinfection system for secondary treatment to improve the purification and disinfection effect. During the application process, the excess undissolved ozone in the water tank will rise to the top space of the water tank, generating ozone tail gas. In order to avoid the pollution of the air environment by such unorganized ozone emissions, an ozone destroyer is usually connected to the water tank to treat the ozone tail gas.

[0004] The ozone exhaust gas treatment method adopted by the ozone destructor is the catalyst method. First, the ozone exhaust gas is introduced into the desiccant cylinder in the ozone destructor. The desiccant dries and absorbs moisture on the exhaust gas, and then the exhaust gas is treated by the catalyst in the catalytic cylinder. Commonly used catalysts include fillers based on manganese dioxide, which can catalytically decompose the ozone exhaust gas and achieve pollution-free emission of the ozone exhaust gas. However, in the process of treating the ozone exhaust gas by the ozone destructor, the operating saturation of the desiccant and catalyst in the drying cylinder and the catalytic cylinder is certain. When the two are saturated, they need to be replaced and maintained. The existing replacement and maintenance process often requires the staff to shut down the ozone destructor for operation, which is easy to affect the treatment operation, and the ozone destructor needs to be disassembled for maintenance, resulting in insufficient convenience and efficiency of maintenance operations. Utility Model Content

[0005] In view of the above technical problems existing in the existing ozone generator in the tail gas treatment application, the utility model provides an ozone generator tail gas treatment device.

[0007] The installation ports are respectively provided with limiting mechanisms for clamping the drying cylinder and the catalytic cylinder.

[0008] Furthermore, two ports of the drying cylinder and the catalytic cylinder are respectively threadedly connected with air permeable covers, and the air permeable covers are provided with a plurality of air permeable holes distributed at equal intervals.

[0009] Furthermore, a sealing gasket is arranged on the inner wall of the notch close to the installation frame, the two ports of the installation frame are respectively arranged to be closed, and a partition is arranged between the opposite surfaces of the two installation ports in the installation frame.

[0012] Beneficial effects of the utility model:

[0013] 1. By sliding the installation frame into the notch on the ozone destroyer, when the desiccant and catalyst in the drying cylinder and the catalytic cylinder in the ozone destroyer need to be replaced after working for a period of time, the installation frame is slid along the notch to slide the drying cylinder or the catalytic cylinder in the ozone destroyer out, and the replaced drying cylinder or the catalytic cylinder is inserted into the installation opening on the other side of the installation frame. With the sliding of the installation frame, one end of the replaced drying cylinder or the catalytic cylinder on the other side is placed in the ozone destroyer, so that the replaced drying cylinder or the catalytic cylinder can replace the original one for operation, which is convenient for online replacement and maintenance of the drying cylinder or the catalytic cylinder in the ozone destroyer, without interrupting the ozone destroyer to treat the ozone tail gas generated by the ozone generator, thereby improving the convenience and efficiency of maintenance operations.

[0014] 2. Move the latch along the slide slot and release the latch from the slot to release the limit on the dryer or catalytic cartridge, then take out the dryer or catalytic cartridge, and then unscrew the breathable cover to facilitate the replacement of the desiccant and catalyst in the dryer or catalytic cartridge. After the maintenance is completed, the next time the ozone destructor needs to replace the dryer or catalytic cartridge, put the dryer or catalytic cartridge to be replaced into the mounting port on the mounting frame outside the ozone destructor to complete a new round of replacement and maintenance operations. The operation is convenient and easy to replace the dryer or catalytic cartridge, ensuring the reliability of the ozone destructor in ozone tail gas treatment operations.
