The surface smoothness of the polyester needle felt felt has a great influence on the dynamic running resistance of the filter material. The initial resistance of the filter depends on the air permeability of the filter itself, and the resistance during operation is many times larger than the initial resistance. The running resistance depends on the smoothness of the surface of the filter material and the cleaning effect.
It is generally desirable that when the filter material is to have the same filtration efficiency, the larger the air permeability, the better, that is, the lower the resistance, the better, because it can save a lot of energy. In the dust remover using gas flow back-flushing, when using the same pressure and same air flow for cleaning, the use of a high-permeability woven fabric as a filter bag results in a better cleaning effect than the use of a low-performance woven fabric. . Therefore, in the case of ensuring that the filter material achieves higher filtration accuracy, how to increase the air permeability of the filter material and increase the degree of surface smoothness, reduce the dust adhesion, and reduce the running resistance are the topics that the filter material production plant should first study. The surface resinized and smooth finished needled filter felt developed by our factory has an air permeability more than 50% higher than the ordinary calendered filter media, and the surface smoothness is smoother and smoother than the calendered finishing.
performance
