Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model.
Specific embodiment
Referring to Fig. 1, the utility model discloses a kind of desulfurizing tower, including tower body 11, ash bucket 12, air inlet distributor 13,
Support tube 31, atomizer 14, dry powder spray head 15, active carbon feeder and pulverized limestone feeder；The ash bucket 12 is arranged described
11 bottom of tower body, the setting of air inlet distributor 13 is at 11 top of tower body and stretches in the tower body 11；The branch
The lower end of stay tube 31 is conical opening and is inserted into from the top of the tower body 11 that the atomizer 14 is arranged in the support tube 31
It is interior；The dry powder spray head 15 setting is in 11 side wall of tower body, and the ejiction opening of the dry powder spray head 15 is towards the tower body 11
Interior, the dry powder spray head 15 is connect with the active carbon feeder and pulverized limestone feeder respectively.
11 surface of tower body is provided with insulating layer 34, and the atomizer 14 is rotary atomizer 14.In the ash bucket 12
Having heaters 25 is set.In the present embodiment, the utility model further includes blow-off valve 21, crusher 22, unloading valve 23, temperature sensing
Device 33 and air bubble 24.12 bottom of ash bucket is provided with outlet 121, and the blow-off valve 21 is arranged in the outlet 121
Lower section.The crusher 22 and the unloading valve 23 are arranged below the blow-off valve 21.The setting of temperature sensor 33 exists
In the ash bucket 12 and it is located at 121 top of outlet.The ejiction opening of the air bubble 24 is arranged on the blow-off valve 21
Side.The blow-off valve 21 is gate valve.The tower body 11 is provided with manhole 35.It is provided with maintenance rig 36 at the top of the tower body 11,
Electric block 32 is provided on the maintenance rig 36, the drag hook of the electric block 32 is connect with the atomizer 14.
The lime white drop that the atomizer 14 is used to for lime slurry being atomized into 20-50 microns sprays into inside extracting tower,
It is reacted with flue gas mixing, on the one hand reduces flue-gas temperature, on the one hand remove sulfide and hydride.In garbage incinerating tail gas
Certain density dioxin is usually contained, therefore considers to adsorb two evils in flue gas by way of spraying into activated carbon in system
English.Before flue gas enters bag filter, the active powdered carbon that granularity is 200-300 mesh is sprayed into flue, into after deduster
These active carbon powders are equally trapped within cloth bag surface, and when flue gas passes through cloth bag, the dioxin in flue gas is because by active carbon
It adsorbs and is purified.Between the incinerator start and stop furnace period, since exhaust gas temperature is low, semidry method deacidification system can not normally be thrown
Fortune, can star dry powder spraying system at this time, achievees the purpose that depickling；New cloth bag needs to carry out in advance cloth bag with pulverized limestone after installing
Spraying, the adding of the system, which makes to be preliminarily sprayed work, to be become to be simple and efficient；During rotary sprayer maintenance, incinerator smoke evacuation is direct
It into bag filter is then easy to that deduster is caused to damage, and starts dry powder spraying system, can both make flue gas row up to standard
It puts and high-concentration acidic wastewater gas is avoided to cause to corrode to bag filter
Reaction tower overall structure plays desulfurizing tower tower body 11 using steel bracket as support, by seat supports, in desulfurizing tower tower
It is covered with insulating layer 34 on body 11, air inlet distributor 13 and tower top maintenance rig 36 are provided at the top of tower body 11.Tower top maintenance is flat
Platform is equipped with electric block 32, passes through support tube as lifting rotary atomizer 14 and other maintenance purposes, rotary atomizer 14
31 are placed on tower air inlet distributor 13, and 14 atomizing disk of rotary atomizer extend into work in desulfurization tower body 11.
When desulfurizing tower is started to work, blow-off valve 21, unloading valve 23, crusher 22 in desulfurizing tower bottom ash bucket 12 are beaten
The electric heater 25 opened, and open ash bucket 12 carries out ash bucket 12 and preheats, and prevents from just entering the flue gas in tower because of abrupt temperature drop
And condensation, heating temperature is detected and is fed back by temperature sensor 33 in ash bucket 12, after boiler induced-draft fan starting, dry-process deacidification system
System starting, white lime dry powder and active carbon powder are injected into desulfurization tower body 11 by dry powder spray head 15, cigarette after boiler startup
Gas enters desulfurization tower body 11 by air inlet distributor 13.After boiler startup, boiler smoke passes through tower by the effect of air-introduced machine
The eddy flow clockwise of air inlet distributor 13 enters desulfurization tower body 11, after the dry powder blend ejected with dry powder spray head 15, continues eddy flow,
It is sufficiently mixed in desulfurizing tower, by the embedded design and downward opening of tower exhaust pass, so that flue gas is in desulfurizing tower
Inside there is the adequately mixing residence time, and is entering follow-up equipment finally by the discharge flue 37 of ash bucket 12.
In above process, a small amount of bulk flying dust rests in ash bucket 12, by unloading valve after being crushed by crusher 22
23 discharge towers then start air bubble 24 if any grey block arch formation, and air bubble 24 sprays high-speed flow and breaks up grey block bridge, break
Except arch formation.It comes into operation after requirement reaching atomizer 14, rotary atomizer 14 is put into support tube using electric block 32
In 31, start rotary atomizer 14, after environment protection emission parameter stability, closes dry powder spraying system, dry powder spray head 15 is closed.When
Rotary atomizer 14 needs repairing when maintaining, and opens double-current spray gun body and sprays temperature lowering water, starting dry powder injection system into desulfurizing tower
System, starting dry powder spray head 15 spray dry powder, guarantee that environment protection emission is up to standard, then hang out the stoppage in transit of rotary atomizer 14.
A kind of Structure of Flue Gas Desulfuration Absorbing of the utility model is stablized, good by desulfurization effect, and desulfuration efficiency is high.
The utility model is not limited to above embodiment, if the various changes or deformation to the utility model do not take off
Spirit and scope from the utility model, if these changes and deformation belong to the claims and equivalents of the utility model
Within the scope of, then the utility model is also intended to encompass these changes and deformation.
