Slip velocity be up to 22 times of individual particle slip velocity；Absorption tower top structure further enhances the return of floccule, enters
One step improves the endocorpuscular bed density of tower so that the Ca/S ratio up to 62, SO in bed2Fully reaction.
(5) the outlet expander section at venturi is provided with water injector, and the atomized water sprayed into is in order to reduce in desulfurization reactor
Cigarette temperature, make cigarette temperature drop to 75 DEG C so that SO2With Ca (OH)2Reaction to be converted into the ion-type that can complete moment anti-
Should.
Flying ash, circulation desulfurization ash carries out the abundant reaction of second step in the tower more than venturi section, generate by-product
Thing CaSO3·1/2H2O, in addition with SO3, HF and HCl reaction generate corresponding by-product CaSO4·1/2H2O、CaF2、
CaCl2·Ca(OH)2·2H2O etc..
(6) ash-laden gas after purifying laterally is discharged from top, absorption tower, and after then turning to enter desulfurization, cleaner unit is carried out
Gas solid separation, makes dust concentration reach 50mg/Nm3Hereinafter, then by air-introduced machine chimney is entered.What removing dust device trapped consolidates
Body granule, by the Desulphurization recirculating system under cleaner unit, returns to absorption tower and continues to participate in reaction, so circulate.
The present invention uses corresponding system to carry out sulfur removal technology.System is prepared by pre-duster, absorbent, absorption tower, thing
The composition such as cleaner unit and blind controller system after material circulation, fresh water (FW) system, desulfurization.
Use technique of the present invention, it is achieved that the utilization of papermaking solid waste burning flying dust, and desulfuration efficiency is up to
93%, not only protect environment but also achieve the components utilising of resource, can be widely popularized and use.
