How to do dust collector
and removal when the gas or smoke dust is sticky?
The need for economic
development is science and technology, and the production of industrial
products also increases with the environmental problems, air pollution, smoke
and dust emission exceed the standard. The situation of air pollution is very
severe. At present, it is necessary to use activated carbon adsorption,
desulfurization and denitrification equipment as well as dust filter dust
remover in order to realize the emission of smoke and dust emission from
industrial enterprises. What is the main dust collector for viscous flue gas
dusting?
Regarding the flue
gas dust remover and filtration in the sticky flue gas, INDRO filtration
introduces it briefly as followings:
-What
is the measure of the adhesion of dust?
What is the
stickiness of dust? The adhesion of dust to the surface of other substances can
be said to be that the dust has adherence, and that the adhesion also has a
strong and weak point. The general adhesion strength is higher than 600Pa,
which is called strong adhesive dust, but between 300 and 600Pa, it is called
medium adhesive dust, like some adhesion strength below 100Pa at more than 60Pa
In other words, it is only slightly adhesive. If adhesion is below 60Pa,
adhesion can be ignored.
-What
are the effects of dust adhesion on dust collector equipment?
If dust collector
pipes have been blocked or there is dust sludge, then this is the phenomenon
after filtering the sticky flue gas. In the past, the dust removal technology
is still relatively backward, so it is also a lot of effort in the maintenance
of dust removal equipment, if it is easy to clean up the dust on the wall of
the equipment can be used reluctantly. But there is adhesive dust on the polar
plate and pole line of the electrostatic precipitator, so it is difficult to
remove. For the bag type dust collector used, it is really a nightmare for the
dust adhesion to the dust collector filter bag, so the number and intensity of
the dust removal should be increased; and for the filter bag filter equipment
used, we know that the filter bag
is the main part of the dust collector. The treatment of this kind of sticky
flue gas, we can reduce the filter area of a single filter bag, increase the
number of filter bags, thereby improving the ash removal effect.
When gas dust is
sticky, normal filter material cannot filter it very well, we shall use PTFE
laminated filter bags, which is with smooth filtration surface,
dust cleaning will be easy and dust will not go into the inside of filter
material to realize surface filtration.
