Description

Technical Field

[0001] The utility model relates to the technical field of smoke exhaust pipe purification devices, and specifically relates to a smoke exhaust pipe purification device. Background Technique

[0002] A smoke exhaust pipe purification device is a device used to treat and purify pollutants such as oil fume and waste gas discharged from a smoke exhaust pipe. These devices are widely used in fields such as catering and industry to protect the environment and people's health.

[0003] A Chinese patent with the publication number CN221452021U discloses a flue gas filtering device for a boiler, which includes a base, a filtering box, a collection box, a filtering and purifying structure, a sliding seat structure, and a telescopic cleaning structure. The filtering box is installed on the upper end surface of the base through a plurality of support legs. An inlet flue is provided at the top of the filtering box, and an exhaust flue is provided on one side of the filtering box. An exhaust fan is installed in the exhaust flue. A box door A with a locking mechanism is provided on the front of the filtering box. When the box door A is closed, it is hermetically connected to the filtering box. A through falling port is provided at the inner bottom surface of the filtering box, and two chutes are vertically opened on the side of the filtering box away from the exhaust flue inside the filtering box. The overall sealing performance of the utility model is good, and the filtering of flue gas is also comprehensive. It is not easy to have the situation that flue gas is discharged without being filtered, so the practicability of the device is effectively improved.

[0004] However, the above patent has the following deficiencies: The above patent can clean the dust on the filter screen through a brush plate. However, during the use process, there will still be oil fume in the waste gas discharged from the smoke exhaust pipe. When these oil fumes pass through the filter screen, they will adhere to the filter screen. At this time, when cleaning the filter screen with oil stains through a brush, not only can it not be cleaned, but it will also pollute the cleaning brush. Therefore, it needs to be improved.
