Glass fiber composite material used in the filter must be fr

April 09, 2019

Along with the application of the glass fiber and its composite materials in the field of industrial application of filter materials, how to select the high cost of the material has become the hot spot of the downstream enterprises.
According to the production process to choose. Dust remover is a dust removal equipment, but also for the production process of service, different production processes, the nature of the gas and dust also have a difference. Selection of the filter, especially in the selection of glass fiber filter material, should according to the production process to choose; smoke gas dust in high dust content, large dust particles diameter and low moisture content, dust particles is not easy to stick process should be selected air permeability of woven fabric filter, satin weave or twill filter. If the dust content in the flue gas is not very high, the dust particles are fine, and the fabric with smaller air permeability is smaller.
Selection of the characteristics of the dust laden gas. Containing the properties of dust and gas is mainly temperature, humidity, chemical composition and gas content and the temperature decided the structure and filter dust removal equipment selection, humidity and dew point temperature also and filter medium; the humidity or high dew point of flue gas should be selected with hydrophobic agent at the treatment of glass fiber filter material; on the reverse blowing bag dust collector for the glass fiber bulked yarn filter, filter speed is not greater than 0.6m/min.
According to the nature of dust to choose. Dust is the main factor of concentration, particle size, viscosity and corrosion, and it is also the main factor that affects the selection of filter media. The dust concentration is large, the lower the filtering wind speed should be taken into account, the negative pressure design and storage, the capacity of dust removal, low concentration of dust concentration, should be appropriate to select a higher filtration wind speed. When the dust concentration is very low, considering the positive pressure design, in order to reduce the cost of equipment. The dust particle size, should be given priority to the intake mode. On the large viscosity of dust, should choose a good surface finish good filter material. And corrosion of large dust should as far as possible to reduce the filtration velocity and the importance of airflow distribution uniformity and to prolong the service life of the filter bag.
