Description

Technical Field

[0001] The utility model relates to the technical field of waste gas filtering, in particular to a dynamic filtering device for printing and dyeing waste gas. Background Art

[0002] In the process of textile processing, textiles need to be printed and dyed. However, printing and dyeing waste gas will be generated in the printing and dyeing process. If these waste gases are directly discharged, they will cause great pollution to the surrounding environment. Therefore, special filtering devices are needed to treat the waste gas generated in the printing and dyeing process.

[0003] For example, patent number CN219023682U is a printing and dyeing waste gas dynamic filtering device, including a cylinder and an air inlet chamber, one end of the air inlet chamber is an air inlet, one end of the cylinder is an exhaust port, a filter assembly is rotatably arranged in the cylinder, the filter assembly includes a filter screen, one side of the filter assembly is provided with a spray assembly, the filter assembly is used to separate the waste gas and impurities in the waste gas during the rotation process, the above document still has deficiencies, when in use, by setting the filter screen, when the waste gas enters the cylinder, the waste gas and impurities in the waste gas are separated during the rotation of the filter screen, the filtered waste gas is discharged from the exhaust port, and the impurities are attached to the filter screen, thereby realizing the operation of separately treating the waste gas and the impurities in the waste gas, and improving the waste gas treatment. In order to achieve the effect, a nozzle is set, and when the filter screen with impurities attached rotates to the nozzle, the nozzle sprays water to wash away the impurities, and the washed impurities and water are discharged from the drain port. In this way, impurities will not accumulate on the filter screen, and the filtering effect is good. After automatic cleaning, there is no need to manually take out the filter screen for cleaning, which improves work efficiency and is easy to use. However, when cleaning is achieved by spraying water, dust and dirt will be mixed in the exhaust gas during the exhaust gas filtering process. The above-mentioned water spraying method will form mud inside the treatment box, causing damage to the inside of the treatment box. When in use, it is inconvenient to clean the filter cartridge. At the same time, the filter cartridge will have a certain loss during filtering. When the filter cartridge is damaged, it is inconvenient to replace the filter cartridge. Utility Model Content
