Bag filter selection elements are as follows:
Bag filter selection, there are several initiatives, the most important soot. Smoke and dust into one of the main factors of air pollution, the basic measure to reduce air pollution is to reduce the emission of harmful substances to the atmosphere. Here to remind everyone in the choice of baghouse have to pay attention to when.
1, the treatment of air flow (Q)
Disposal of air volume refers to the volume of dust removal equipment in the unit of time can purify the gas volume. The unit is cubic meters per hour (m3 / h) or standard cubic meters per hour (Nm3 / h). Bag filter design is one of the most important elements.
2, the use of temperature
The bag filter, the application of temperature depends on two factors, the first is the maximum temperature of the filter media, the second is the gas temperature must be above the dew point temperature. At present, due to the large selection of glass fiber filter, the maximum operating temperature up to 280 ℃, the gas above this temperature must take cooling measures, the gas below the dew point temperature must take temperature measures. The bag filter, the use of temperature and dust removal efficiency is not obvious, which is different from the ESP, the ESP, the temperature changes will affect the specific resistance of the dust and other dust removal efficiency.
3, the entrance dust concentration
Ie the inlet dust concentration, which is dictated by the dust-point process, is another important element after the design of the bag filter. Expressed in g / m3 or g / Nm3.
4, export dust concentration
The concentration of dust in the mouth refers to the concentration of dust discharged from the dust collector, which means that the dust concentration in the inlet is the same as the dust concentration in the inlet. The dust concentration at the outlet shall be subject to local environmental pleadings or user requests. / Nm3 the following.
5, pressure loss
The pressure loss of dust removal refers to the pressure drop of the gas from the inlet to the outlet of the precipitator, or the resistance.
6, operating pressure
The operation pressure of the dust collector is based on the static pressure value of the breeze blower before and after the dust collector and its installation position, and is also the design pressure value of the bag dust collector.
7, filter speed
8, choose a good filter cloth, the heart of the filter is the filter cloth, filter cloth directly affects the quality of use and use of the cycle!
Filter speed is an important element in the design and selection of baghouse filters. It is defined as the rate at which the filtered gas passes through the filter, or the ratio of the volume of air passing through the filter to the area of the filter. Unit with m / min to represent.
