Description
Technical field
The utility model relates to a kind of spray column, particularly a kind of spray column of the wet process of FGD using for thermal power plant.
Background technology
As everyone knows, coal is the main fuel of thermal power generation, contains a large amount of element sulphurs in coal, during burning, can produce a large amount of sulfide.In this field, the desulfur technology of employing is mainly wet process of FGD at present.Due to spray column have internals less, be not easy the advantages such as fouling, meanwhile, spray column can make flue gas, and slurries are reverse contacts with washing, are more conducive to the absorption to sulfide.Therefore spray column is the main flow tower of wet desulfurizing process.In sweetening process, because the washing slurries near tower wall in spray column are less, and the air pressure in this region is lower, and flue gas can flow to spray column wall place, and flue gas is very easily escaped herein, causes washing the sulfide trapping ability extreme difference of slurries to tower wall place.Prior art is provided with guide ring on spray column for this reason, and flue gas is flowed to spray compact district along guide ring.The guide ring of prior art is arranged on the below of shower place plane, and guide ring can improve washing slurries to sulfide trapping ability, but in the prior art, above guide ring, can form dead angle, causes a part of sulfide not to be captured.Affect washing slurries to sulfide trapping ability, caused desulfuration efficiency to reduce.Add existing guide ring consumptive material more, cost is higher, installs and maintenance inconvenience, in the urgent need to a kind of guide ring of more optimizing, replaces existing guide ring.
Utility model content
The purpose of this utility model is to provide a kind of novel spray column for wet process of FGD, its guide ring is a planar design, guide ring is located at the slightly below of shower nozzle on shower, this can be avoided the dead angle of guide ring top to produce, this guide ring is simple in structure, easy to installation and maintenance, key is to make desulfurized effect be improved greatly.
The technical solution of the utility model: a kind of novel spray column for wet process of FGD, comprise spray column entrance, spray column outlet, spraying layer and demist layer, spray column body below is provided with spray column entrance, spray column body top is provided with spray column outlet, between spray column entrance and spray column outlet, be provided with 3～5 layers of spraying layer, between spray column entrance and spraying layer, be provided with demist layer, on spray column madial wall, be provided with guide ring, guide ring is flat circle ring flat-plate, on shower in guide ring and spraying layer, the horizontal range of the shower nozzle lower end of outermost end is 30mm～50mm.
The aforesaid novel spray column for wet process of FGD, the outer ring of guide ring is circular, the inner ring of guide ring is provided with dentation.Circular outer ring can guarantee with spray column madial wall good fit, flue gas can not be escaped, and dentation can be torn the flue gas entering in spray column, increases the contact area of sprayed slurry and flue gas, sprayed slurry is fully reacted with flue gas, improve desulfuration efficiency.
The aforesaid novel spray column for wet process of FGD, dentation be shaped as V-arrangement, evagination circular arc or indent circular arc.
The aforesaid novel spray column for wet process of FGD, the outer ring of guide ring is connected on spray column madial wall, and guide ring can be used welding, bolt to connect or gluing connected mode.
The aforesaid novel spray column for wet process of FGD, on the inner ring of guide ring and shower, the shower nozzle of outermost end, on same vertical line, guarantees spray area with this, and flue gas can not be escaped, and improves the desulfuration efficiency of spray column.
The aforesaid novel spray column for wet process of FGD, the inner ring of guide ring is 460mm～740mm apart from the distance of spray column madial wall.
The aforesaid novel spray column for wet process of FGD, the inner ring of guide ring is 560mm apart from the distance of spray column madial wall, this distance is the distance of water conservancy diversion and desulfurized effect the best.
Compared with prior art, the utility model can be eliminated guide ring Dead Core Problems around in spray column, increase to greatest extent the response area of washing slurries and flue gas, improved the trapping ability of washing slurries to sulfide, and then improved the desulfuration efficiency of spray column.In addition, this guide ring is simple in structure, production cost is lower and very easily install and keep in repair, and has reduced dramatically production cost.
