Chimney is connected, and the pans are connected and the slurry storage tank and the centre with the slurry storage tank for the calcium hydroxide slurries that are stored with
The connecting pipeline of tank is provided with regulating valve and mass flowmenter；Calcium hydroxide slurries are pumped into the pans, pans through slurries
Interior slurries high pressure injects the serous granule cutter, and slurries enter through serous granule cutter cuts into droplet with smoke air inlet
The sour gas reaction entered, reaction generation dryness particle is discharged through the ash-discharging device, and reacted gas is from flue gas gas outlet
Into the flue gas processing device, the gas after being handled through flue gas processing device is discharged from blowdown stack.
Above-mentioned technical proposal is further improved, the solid content of the calcium hydroxide slurries is 10%.
Further, the cutting accuracy of the slurries cutter is 50um.
Further, the flue gas processing device includes flue, dust arrester, the air-introduced machine being sequentially connected.
Further, the flue be carbon steel material, the dust arrester be fiber bag precipitator, the air-introduced machine be from
Wind formula single suction air-introduced machine.
Further, the tower container material quality is that carbon steel applies squama.
Further, provided with double-current spray gun body in the tower container.
Using the method for the progress smoke gas treatment of above-mentioned special boiler of power plant fume environment protection abatement equipment, including following step
Suddenly：
（1）The calcium hydroxide slurries high pressure of solid content 10% is injected into serous granule cutter；
（2）Slurries are reacted through serous granule cutter cuts into 50um droplet with pending flue gas；
（3）The solid of reaction generation is discharged through ash-discharging device, and reacted gas is after dust arrester after-treatment by drawing
Blower fan is discharged.
Beneficial effect：Tower upper vessel portion of the present invention injects absorbent, and absorbent is can adjust concentration, in slurries storage
Deposit and regulating valve and mass flowmenter are set on the connecting pipeline of tank and pans, can be dense according to flue gas sulfur-bearing by control system
Degree carries out Flow-rate adjustment：It is just chain when flue gas sulfur content is high to tune up control valve opening, so that increase the quantity of absorbent,
Ensure that depickling reaction is normally carried out, vice versa, so as to realize the SO according to acidic flue gas2Determine with HCL concentration regulation slurries pump
Amount input is a variety of containing sulphur concentration to adapt to pans, can adapt to many varying duties of boiler；
Existing many reaction units, such as CFB devices, very sensitive to load variations, regulation needs longer time, it is necessary to accumulate foot
Enough beds and the time for setting up thickness of bed layer；Meanwhile, load variations need certain adjustable range, and such as 30% load is to leave the bed
Layer is substantially difficult to set up, so that bed stoppage in transit phenomenon of collapsing；The present invention does not have substantially because depickling principle is active atomizing
The interference of situation described above, the need for disclosure satisfy that stable operation；The sorrow poisoned in governance process without collapse bed or slurries；Increase
Plus fault reaction device disclosure satisfy that the average requirement of environmental administration's smoke emissioning concentration；It disclosure satisfy that non-wastewater discharge requirement；
Water consumption very little, also disclosure satisfy that the environmental requirement of northwest water-deficient area power plant in addition to for special power plant.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Embodiment
Technical solution of the present invention is described in detail below by accompanying drawing, but protection scope of the present invention is not limited to
The embodiment.
Embodiment 1：Special boiler of power plant fume environment protection abatement equipment as shown in Figure 1, location arrangements are in boiler tail cigarette
