How to choose dust collector equipment

Speaking of dust collector equipment, I believe that friends should be familiar with it. So, do you know how to choose dust collector equipment? I have summarized the following points and share them with you:


 1. Processing air volume

  The processing air volume refers to the volume of gas that the dust removal equipment can purify per unit time. The unit is cubic meters per hour (m3/h) or standard cubic meters per hour (Nm3/h). It is one of the most important factors in the design of dust collector equipment.


 2. Using temperature

  For dust collector equipment, its operating temperature depends on two factors. The first is the maximum temperature of the filter material, and the second is that the gas temperature must be above the dew point temperature. At present, due to the large selection of glass fiber filter materials, the maximum operating temperature can reach 280°C. Cooling measures must be taken for gases above this temperature, and warming measures must be taken for gases below the dew point temperature. For dust collector equipment, the relationship between operating temperature and dust removal efficiency is not obvious. This is different from electrostatic precipitator. For electrostatic precipitator, changes in temperature will affect the specific resistance of dust and other factors, which will affect the dust removal efficiency.  


 3. Pressure loss

    The pressure loss of the dust collector equipment refers to the pressure drop of the gas from the inlet to the outlet of the dust collector, or resistance.


 4. Operating pressure 

    The operating pressure of the dust collector equipment is determined by the static pressure value of the devices before and after the dust collector and the fan and its installation position. It is also the design pressure value of the dust collector equipment.


 5. Filtration speed 

    Filtration speed is an important factor in the design and selection of dust collector equipment. It is defined as the speed at which filtered gas passes through the filter material, or the air volume passing through the filter material and the area of ​​the filter material.
