Three factors that affect the efficiency of air filters

1, air filter filter bag information:

The selection and use of filter bag data is the core skill of bag dust collection equipment, which plays a decisive role in the function of air filter dust collector. Due to the environment of each dust collection point, the nature, temperature and skill requirements of the dust treatment are not the same, and different filtration data should be selected for different conditions, and corresponding technical protection measures should be adopted. The requirements for filter bag data include the following skills: filter bag data is suitable for different temperatures, good stripping, easy cleaning, good air permeability, low resistance, high filtration efficiency, high strength, can accept high strength cleaning, long service life, and suitable price.

2, air filter leakage:

Air leakage directly affects the dust collection effect and life of the dust collector, and the air leakage rate is required to be <3%. Bag type dust collector is generally negative pressure operation, such as air leakage is easy to form a small circuit short circuit. The dust collection system can not handle the air volume, which constitutes positive pressure dust. Air leakage will also reduce the temperature of the system, easy to generate moisture paste bag, increase the dust collection resistance, and reduce the filtration effect of the filter equipment.

3, air filter wind speed:

The filter wind speed is a very important parameter to determine the function of the dust collector, and it is also an important parameter to measure the performance of the bag dust collector. The filtration speed is closely related to the dust concentration, dust particle size, application occasions, viscosity, gas temperature, moisture content and cleaning method of the dust containing gas. When the dust particle size is fine, the temperature and humidity are high, the concentration is large, and the viscosity is large, the filter wind speed should be lower, and the other way around, the higher value can be selected. The filter wind speed is too large, will aggravate the filter bag load, increase the filter resistance, resulting in short service life of the filter bag, low efficiency.
