The desulfurization complete set of equipments developed etc. principle, in the patent No.：ZL 20,122 0165655.0, using rotating stream tray construction unit body group
High magnification, comprehensive, all standing type Wet-type high-efficient flue gas purification system are synthesized, comprehensive is implemented to the harmful substance in boiler smoke
Purification.Using rotating stream tray scrubber flue gases purification, with operating flexibility is wide, load range is big, SR is small, gas-liquid contact face
Product is big, and infiltration rate is fast, and purification efficiency is high, the features such as desulfurization and dedusting is synchronously carried out and advantage.
It is as follows that the utility model solves problem using the combination emphasis of desulfurizing tower and chimney：
Flue gas with water after solving the problems, such as to handle through wet desulphurization is intended to using nicotinic acids scheme, is generally acknowledged maximally efficient
Processing flue gas in method, its efficiency high is stable, emission compliance, and nicotinic acids scheme avoids flue gas laggard through desulfurizing tower
Flue enters smoke stack emission again, and reduce flue gas flow reduces hydrogenesis chance in flue gas naturally.Nicotinic acids are i.e. in desulfurizing tower dress
Put and directly connect stainless steel stack above 35 outlets, once moisture condenses to the cold in flue gas, can be again flowed into along chimney wall in tower,
Greatly the infringement that flue gas with water is caused to flue stack is solved, and the moisture in desulphurization circulating is more made full use of no matter
The working condition of northern boiler is all very suitable for from technology or Energy Angle.And the advantage that four desulfurizer devices 35 are unified exists
In：Nicotinic acids scheme technically haves the advantages that obvious but inevitable there is also certain difficult point, that is, it is big to build difficulty,
So it is how that the construction of nicotinic acids is more rationally economical, it is the problem of must solving.Using 200 tons of desulfurizing towers of separate unit as
Example, to meet service condition, calculates 21 meters of tower height, the smoke adding chimney on tower, need to meet design specification and chimney builds specification through design
It is required that, whole nicotinic acids height also needs to arrange detection platform, inspection platform up to 60m on chimney.Platform needs supporting word
Ladder, and desulfurizing tower needs also exist for arrangement inspection platform and maintenance ladder in process of construction, so the utility model design will be de-
Sulphur tower ladder and chimney detection ladder and two are one, and it is one that ladder needed for four desulfurizing towers is closed into four：Four desulfurizing towers are adopted
With centralized arrangement, flue gas is discharged through a chimney after such a arrangement handles four desulfurizing towers, substantially reduces construction cost, and use
This combined layout mode ladder landing platform can be public, and all bases and support can be used and once completed, it is not necessary to repeated construction.This
Outside, four nicotinic acids (four desulfurizing towers above share a chimney) scheme, desulfurization uses tower outer circulation, newly-built desulphurization circulating pond and
Between auxiliary device, four tower centralized arrangements not only air inlet/outlet arrangement is convenient, and serum recycle also can centralized arrangement arrangement pipeline, saving
Construction cost, economic feasibility is high.
Present embodiment is the exemplary illustration to this patent, does not limit its protection domain, people in the art
Member can also be changed to its part, as long as no the Spirit Essence beyond this patent, all in the protection domain of this patent.
