Description
Technical field
The utility model designs desulfuration absorbing tower device field, more particularly to a kind of spray Rotating fields of nozzle differentiation.
Background technology
Absorption tower in wet desulfurizing process is the key equipment of whole desulphurization system, and spraying layer and nozzle are to inhale
Receive most crucial equipment in tower, the air flow method in the nozzle covering of spraying layer and tower directly decides absorption efficiency.
Existing absorption tower is all to be uniformly distributed to be designed by the velocity field of flue gas, pressure field in tower, while spraying layer
Nozzle be also by be uniformly distributed design.But being evenly arranged for nozzle can cause the coverage rate in tower wall region far below flat
Equal coverage rate, finally make it that the side wall area resistance in whole absorption tower interface is small, central area resistance is big.Absorption tower center
Area resistance is big, causes flue gas tower tower wall to escape, so as to influence desulfuration efficiency.
Currently used way is to do a ring plate along tower wall in the lower section of spraying layer, by flue gas guiding centre region, with
Flue gas is avoided to be escaped along wallboard, short circuit.This way there is it is certain the defects of, including slurries easily top surface deposit, the time
Long ring flat-plate and the tower wall anticorrosive coat can be caused to come off；Aditus laryngis throttling is formed in ring flat-plate layer so that SR increase simultaneously.
In summary, in the prior art for the problem of the absorption efficiency of absorption tower, still lacking effective in raising desulphurization system
Solution.
Utility model content
For overcome the deficiencies in the prior art, the utility model provides a kind of spray Rotating fields of nozzle differentiation, leads to
The high coverage rate that to spraying layer progress subregion and the design of nozzle differentiation, can be realized in tower, high-selenium corn efficiency are crossed, is eliminated simultaneously
Flue gas is escaped along tower wall, short circuit phenomenon.
The utility model uses following technical proposals：
A kind of spray Rotating fields of nozzle differentiation, are arranged in wet flue gas desulfurization absorption tower, spraying layer are divided
Area, described spraying layer include central area and the tower wall region on the outside of central area；Spray on described tower wall region
Mouth number is more than the number of nozzle of central area；While high-selenium corn removal efficiency is ensured, by sprayed slurry by tower wall flue gas
Guiding centre region, avoid flue gas from being escaped along tower wall short-circuit, and realize the lower resistance operation on absorption tower.
Further, the number of nozzle in described tower wall region is 1.1-1.15 times of average jet nozzle density.
Further, the number of nozzle of described central area is 0.85-0.9 times of average jet nozzle density.
Further, the nozzle on described tower wall region uses 90 ° of solid-cone (type) nozzle.
Further, the nozzle on described central area uses 90 ° or 110 ° of hollow cone nozzle.
Further, twice of annular width in the diameter of a diameter of central area of absorption on absorption tower and tower wall region it
With.
Compared with prior art, the beneficial effects of the utility model are：
(1) the utility model carries out subregion to spraying layer, and spraying layer is divided into central area and tower wall region, is easy to rationally
Change distribution nozzles density；
(2) the utility model is designed using nozzle differentiation, and the number of nozzle on tower wall region is set greater than into center
The number of nozzle in region so that the sprinkle density in tower wall region is big, coverage rate is high, is ensureing the high-selenium corn removal efficiency on absorption tower
Meanwhile by sprayed slurry by tower wall flue gas guiding centre region, flue gas is avoided to be escaped short circuit along tower wall, and from realizing absorption tower
Lower resistance operation.
