How to choose the pulse dust collector correctly?

The application of pulse dust remover is very wide, so when enterprises choose pulse dust remover, what should they pay attention to? The following is how to choose pulse dust remover:

<1> in the pulsed dust collector, dust is attached to the wall surface due to centrifugal force, and there is the risk of blockage;However, the dust attached to the bag pulsed dust collector will easily block the hole of the filter bag, and the dust will easily accumulate on the discharge electrode and dust collecting pole of the electric pulsed dust collector.

< 2 > when choosing a type of pulse filter, need is to understand exactly dust dispersion, such as particle size of more than 10 nu m in more optional pulse dust collector.If the particle size is more than a few microns, electrostatic pulsed precipitator and bag pulsed precipitator should be selected. The specific selection can be made by referring to the types and performance tables of commonly used pulsed precipitator according to the dispersion degree and other requirements.Then according to other conditions and introduced the pulse dust collector type and performance determination.Dust density has a great influence on dust removal performance of pulsed dust remover.The effect is apparent in the form of gravity.

<3> dry dust removal equipment in principle in the dust containing gas above the dew point temperature.In wet pulsed precipitators, water evaporation and condensation after discharge to the atmosphere should be treated as low as possible.In a pulse filter, the temperature of directly or indirectly treating the dusty gas should be reduced below the heat-resistant temperature of the filter cloth.

<4> how much to deal with the gas is the decisive factor to determine the size of the pulse dust collector type, for large gas volume, to choose the pulse dust collector can deal with large gas volume, if multiple pulse dust collector to deal with small gas volume parallel use is often uneconomic;Which kind of pulsed dust precipitator is economical and easy to meet the environmental requirements of dust source point control and dust emission.

<5> inertia force and centrifugal force pulse dust collector.One thing all pulsed dust precipitators have in common is that the smaller the accumulation density is, the more difficult it is to separate and collect dust particles and the more serious the secondary dust flying is. Therefore, special measures should be taken in operation and equipment structure.

<6> the higher the dust concentration at the entrance, the higher the dust removal efficiency, but this will increase the dust concentration at the exit, so it is not only from the dust removal efficiency is generally considered that dust treatment effect is good, for the wet pulsed dust precipitator, jet scrubber and other wet pulsed dust precipitator, the initial dust concentration below 10g/m is appropriate;For the bag pulsed precipitator, the lower the dust concentration is, the better the performance is.Continuous ash cleaning, pressure loss and emission concentration can also meet environmental requirements.
