  • Turbulence device used for air filtration system
    Patent number: 7704293
    Abstract: The invention is related to a turbulence device used for air filtration system. The turbulence device comprises a porous plate and a spoiler. The porous plate has a plural number of holes located on one side of the spoiler. The spoiler has a square hole. The turbulence device in the invention is used for an air filtration system and its testing to increase even mixing of the air and a plural number of fine particles in the air and increase the efficiency for the air filtration system. In the testing of the air filtration system, even mixing of the air and the fine particles can improve the accuracy of the air filtration system and avoid the use of unqualified air filtration system to harm the environment.
