High-efficiency filter surface speed, dust holding capacity and The service life is roughly fixed. Generally, air filter manufacturers also recommend its service life based on the environment in which the customer uses it, and judge the ventilation volume of the high-efficiency filter based on its size.
1. High-efficiency filterFacial speed and filtering speed
Measuring efficient filtering The ability of the processor to handle air volume is usually expressed in terms of surface velocity, Sometimes it is also expressed as filtering speed, For plate filters, the two are the same. Facial velocity refers to the airflow speed passing through the filter section, generally expressed as m/s. The filtration speed refers to the air flow speed through the filter material area of the filter. Due to different requirements for high-efficiency filters, The filter material area set in the filter is also different,sometimes larger than the filter The broken area is dozens of times. Therefore the filtration speed is smaller than the surface speed , Usually expressed in m/min or cm/s. The size of the filtration speed is directly related to the performance of the filter. A filtration speed that is too high will reduce the purification efficiency, Increase resistance. Therefore in order to reduce resistance , The filtration speed of high-efficiency filters is usually very small, and the area of the filter material is very large.
2. High-efficiency filterDust holding capacity and lifespan
The dust holding capacity of the air filter refers to the rated amount of dust that the filter can accommodate and intercept when the initial resistance changes from the initial resistance to the final resistance. , The amount of dust on the transition area per meter2（kg)expression.For high-efficiency filters,dust holding capacity is higher than that of ordinary industrial dust collectors（such as bag dust collector)more important meaning, Because when the dust collector reaches the rated dust holding capacity, often pass Dust cleaning causes the dust adhered to the filter material of the dust collector to fall into the ash hopper, Resistance decrease,Restore to close to its original state. But this is not the case for air filters , After the filter reaches the rated dust holding capacity, it needs to be removed, cleaned and regenerated（Rupaopao Filter), Sometimes the filter material is replaced . Therefore, the size of the dust holding capacity also determines the life of the filter font>. Dust holding capacityyue大, Filter lifespanYuelong,It can be seen that the dust holding capacity is an important performance indicator indicating the life span of the air filter. The amount of dust holding capacity is related to the high-efficiency filter material, compareThe ideal crossing material structure is a gradient structure,i.e. The structure of the filter material transitions from loose to dense,This structure can not only obtain a larger dust holding capacity, and achieve good efficiency.
