The selection of dust collector skeleton matters needing attention: the selection of a good dust collector skeleton is an important factor for the daily operation of dust collector. The bag type dust collector with different cleaning methods should choose different types of structure filter material because of the different cleaning energy and filter bag shape change characteristics. On the general filter material surface coating, pressing and other post-processing can also be advanced.
About glass fiber filter material, silicone oil, graphite, ptfe resin treatment can improve the folding resistance. However, the film coated filter material is used in the condition of strong wear, the film will wear out prematurely, lose the film coating effect. The framework of the precipitator can induce the short-range collecting mechanism of dust, such as formation, direct interception, dispersion settlement, inertia bump and electrostatic adsorption.
When the dusty air through the grid, fabric, nonwoven cloth, foam and other filter material, dust in the filter material inside or outside of the dust layer, and the upper layer of the powder formed by the filter layer, so that it is separated from the air flow. Oscillating back blowing and bag type dust collector refers to the bag type dust collector which has the functions of both oscillating and reverse air flow. The oscillation loosens the dust cake, and the adverse airflow loosens the dust. The two methods cooperate with each other to advance the cleaning effect, especially for fine particles of sticky dust.
Influence of the size of the dust skeleton: in the size of the dust skeleton, the diameter of the dust skeleton, the gas inlet and the shape and size of the exhaust pipe are important influencing factors. The influence of gas parameters on the function of dust skeleton includes the influence of gas flow, dust concentration, moisture content, density, viscosity, pressure and temperature of gas, etc.
