transfer, and collision in the foam area are strengthened to achieve the purpose of
efficient dust removal.
Experimental Method
The experiment uses an isokinetic sampling method [13], using a dust sampler
to simultaneously collect the quantitative gas at the inlet and outlet into a collection device equipped with a microporous membrane. The formula of dust mass
concentration as follows:
C =
3.6 × 10
6 m
t · q
(1)
where C: dust mass concentration, g/m
3 ; m: dust mass, g; t: sampling time, s; q:
sampling rate, L/min.
The formula of dust removal efficiency as follows:
η = 1 −
C 1
C 0
(2)
where η: dust removal efficiency, %; C 0 : inlet dust concentration, g/m
3 ; C 1 : outlet
dust concentration, g/m
