xrespectively not higher than 10mg/Nm
3, 35mg/Nm
3, 50mg/Nm
3emission limit.
Along with the raising of national environmental standard, built desulphurization system arranges SO outward
2, flue dust is not up to standard, need capacity-increasing transformation, but do not have again place to transform, can only try every possible means on former desulfuration absorbing tower like this.In conventional desulfurization absorption tower, the above diameter of spraying layer and absorption tower diameter unanimous between the higher and lower levels, minimum discharge environmental requirement can not be met.Meet flue gas after the dedusting demist section reducing of former desulfuration absorbing tower and reach controlled range by the flow velocity of demister, just solve dedusting day with fog discharge < 10mg/Nm
3up to standard, be discharged in air would not have gypsum rain and flue dust up to standard.Therefore to existing environmental protection facility carry out minimum discharge transformation be necessary.
