Description
Technical field：
It the utility model is related to technical field of dust removal equipment, and in particular to a kind of boiler desulfurization deduster.
Background technology：
Boiler dust remover is the necessary component of coal-burning boiler system, because it has dedusting, desulfurization and other effects, is always
An indispensable part in boiler operatiopn system.Existing boiler dust remover mainly divides ceramic multi-tube cyclone dust collectors, wet type
Desulfurizing dust-collector, sack cleaner and electrostatic precipitator, and latter two is mainly large-sized station boiler is used, China is current
Industrial Boiler is based on first two, and ceramic multicyclone dust collector is double because can only achieve dust removing effects, can not exclude in flue gas
Sulphur, substantially also in eliminate state.Therefore, the existing Industrial Boiler in China is mainly based on wet type desulfurizing dust collector.But
It is that current wet type desulfurizing dust collector desulfurized effect is poor.
Utility model content：
Technical problem to be solved in the utility model is to overcome existing technological deficiency, there is provided a kind of boiler desulfurization removes
Dirt device.
Technical problem to be solved in the utility model is realized using following technical scheme：
A kind of boiler desulfurization deduster, including tower body, the tower body bottom side of the wall are provided with smoke inlet, and tower body top is provided with out
Mouth, spray thrower, packing layer, demisting layer are sequentially provided with the tower body from bottom to up, and spray thrower is connected outside tower body by pipeline
The slurry pool in portion, the tower body is interior to be provided with helical intake below spray thrower, and the helical intake bottom has import, and import is led to
Cross the outlet that helical intake is connected to back taper enlarging bottom, back taper flared upper part it is consistent with tower body shape and with tower body it
Between it is gap-free sealed, the helical intake lower edge and tower body are gap-free sealed.
The back taper flared side walls have opening, and opening is connected to below helical intake by induced-draught fan and airduct.
Sulfur dioxide detector is installed, sulfur dioxide detector connects PLC with induced-draught fan at the outlet flue.
The tower body bottom has recovery pond, and recovery pond connects outside purification tank for liquid waste by water pump.
Calcium hydroxide slurries are full of in the slurry pool.
Installation abacus, orifice plate are welded in back taper enlarging by supporting leg above the outlet of the back taper enlarging bottom
Wall.
The beneficial effects of the utility model are：By boiler exhaust gas by helical intake, the slurries pair under being sprayed using spray thrower
Flue gas carries out desulfurization, and slurries form serosa in helical intake inwall, and helical intake stroke is grown, and adds slurries and flue gas
Contact area, and the scattered slurries that flue gas further can also spray after exporting away with spray thrower continue haptoreaction, make
Obtain desulfurized effect to greatly improve, demisting layer is used to remove moisture.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model.
Embodiment：
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
As shown in drawings, a kind of boiler desulfurization deduster, including tower body 1, the bottom side of the wall of tower body 1 are provided with smoke inlet 2, tower body
1 top is provided with outlet flue 3, is sequentially provided with spray thrower 4, packing layer 5, demisting layer 6 in tower body 1 from bottom to up, is provided with demisting layer 6
Drier, spray thrower 4 have multiple sprinkler heads, and spray thrower 4 connects the slurry pool 14 outside tower body 1 by pipeline, tower body 1 it is interior
The lower section of spray thrower 4 is provided with helical intake 7, and the bottom of helical intake 7 has import, and import is connected to back taper by helical intake 7
The outlet of the bottom of enlarging 8, the top of back taper enlarging 8 is consistent with tower body shape and gap-free sealed between tower body 1, spiral gas
The lower edge of road 7 and tower body 1 are gap-free sealed.
The side wall of back taper enlarging 8 has an opening, and opening is connected to below helical intake 7 by induced-draught fan 9 and airduct, can be with
The flue gas after desulfurization is then sent through entrance using induced-draught fan and goes successively to helical intake to desulfurization.
Sulfur dioxide detector 10 is installed, sulfur dioxide detector 10 and induced-draught fan 9 connect PLC controls at outlet flue 2
Device 11.When sulfur dioxide detector detects that discharge flue gas sulfur content is high, signal is transmitted to PLC, then controls induced-draught fan
Open, flue gas is sent to entrance.
The bottom of tower body 1 has recovery pond 12, and recovery pond connects outside purification tank for liquid waste by water pump.
Calcium hydroxide slurries are full of in slurry pool.Calcium hydroxide slurries are used for and smoke reaction desulfurization.
Installation abacus 13, orifice plate 13 are welded to back taper enlarging by supporting leg above the outlet of the bottom of back taper enlarging 8
Inwall.Flue gas is out of orifice plate hole by the way that the hole wall of orifice plate has serosa, further increases flue gas and slurry liquid contacts face
Product, greatly improves desulfurized effect.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
