Double-column in series structure, it is by first grade desulfurizing tower, two-grade desulfurizing tower, chimney and technique building, water circulating pump, oxidation fan, gypsum pump
And technique water system is formed, this structure has shortcoming：(1) flue gas returns to two level from first grade desulfurizing tower top about 32m eminences
Desulfurizing tower bottom 9m eminences, then from two-grade desulfurizing tower 32m eminences, return at chimney lower inlet, flue height shuttle route
Long, as many as six, elbow, SR is big, about 500Pa；(2) floor space is big：Two-grade desulfurizing tower, chimney and technique building, circulation
Water pump, oxidation fan, gypsum pump and technique water system, floor space are even more more typically at 300-400 square metres；(3) it is existing
Steel straight-line desulfurizing tower fume emission is highly low, does not meet code requirement, majority difference 20m or so.
The content of the invention
The purpose of this utility model is to provide a kind of overhead smoke-gas wet desulfurization tower, past to solve prior art flue gas height
Return route length, the problem of elbow is more, and SR is big, and floor space is big, and straight-line desulfurization tower height degree does not meet code requirement.
What the purpose of this utility model was realized in：The overhead smoke-gas wet desulfurization tower, including first grade desulfurizing tower, two level
Desulfurizing tower and chimney, it is characterised in that：Two-grade desulfurizing tower be seated in it is overhead upstairs, flue gas from first grade desulfurizing top of tower by connect cigarette
Road is directly entered two-grade desulfurizing tower bottom, is provided with high-pressure flushing device in connection flue, two-grade desulfurizing tower uses straight-line, cigarette
Chimney is fixed on two-grade desulfurizing tower top, and inspection platform is provided with overhead roof, and inspection platform is connected with stair.
The connection flue of first grade desulfurizing tower and two-grade desulfurizing tower is inclined upwardly 5-10 degree angle, into two-grade desulfurizing tower after connect
Flue tilts down 10-20 degree angle.
There is 18-20 rice in overhead building, divides three layers, one layer has between oxidation fan, transport channel, office and gypsum；On two layers
There are water tank, cooling water pump, flush water pump, water circulating pump, gypsum pump and oxidation fan, three layers have transformer, Central Control Room, online inspection
Room and vacuum belt filter are surveyed, cooling water pump, flush water pump, water circulating pump, gypsum pump are sprayed with desulfurizing tower respectively by pipeline
Layer water circulation system and connect flue inner high voltage flusher and be connected, Central Control Room by circuit with, gypsum pump, water pump electrical equipment is connected
It is logical.
The utility model has advantages below compared with prior art：(1) desulfurizing tower build in it is overhead upstairs, with overhead building knot
A desulfurizing tower main body is synthesized, the height of straight-line desulfurizing tower adds about 20m, meets HJ2050-2016《Steel and iron industry sinters
Machine flue-gas desulfurizing engineering technical specification Wet Limestone/lime-gypsum method》6.5.11 middle regulation requires：In line desulfurizing tower chimney
The highly minimum requirement that cannot be less than 70m；(2) connection flue is inclined upwardly 5-10 degree angle, into two-grade desulfurizing tower after connect cigarette
Road tilts down 10-20 degree angle, so can both reduce resistance, can increase residence time of the flue gas in two-grade desulfurizing tower again；(3)
High-pressure flushing device is provided with connection flue, can prevent from connecting flue fouling；(4) first grade desulfurizing tower flue gas is directly communicated to two level and taken off
Sulphur tower, two-grade desulfurizing tower flue gas are expelled directly out by chimney, and flue gas returns under not having to, and flue can reduce about more than 40m, save material
Reduce cost；(5) floor space is small：Save chimney and technique building, technique water system, oxidation fan, gypsum pump and related
The floor space of auxiliary device, about 300-400m2；(6) overhead portion downstairs is provided with transport channel, two-grade desulfurizing tower make after just
Installed in transport, beneficial to the old device of transformation.
