Feature of the present utility model also is, inner core and urceolus bottom are inverted cone-shaped structure, and turbine mechanism is arranged on the exit, lower end of inner core inverted cone-shaped structure, and blowoff valve is arranged on the exit, lower end of urceolus inverted cone-shaped structure.
Aperture is arranged on the sidewall of the inverted cone-shaped structure bottom inner core.
Dewatering device is near the exhanst gas outlet setting, and dewatering device is centrifugal drier.
The urceolus top is provided with back purge system.
The beneficial effects of the utility model are:
1) the utility model can make the flue gas that coal-burning boiler is discharged fully contact with recirculated water for a long time and merge washing, and the dust-removal and desulfurizing effect is good, also has the effect of denitration, denitrogenation and removing heavy-metal;
2) there is not traditional coal-fired boiler smoke purifying device spray nozzle clogging problem in the utility model, and the operation troubles rate is low continuously, and maintaining is simple;
3) the utility model can make the central alkaline components of flue dust fully be dissolved in recirculated water, strengthens desulfurized effect, thereby reduces the use of desulfurizing agent;
4) the utility model uses recirculated water to carry out dust-removal and desulfurizing, and rate of water make-up is little, can reduce the waste of water resource.

In figure, 1. inner core, 2. urceolus, 3. admission line, 4. shower, 5. aperture, 6. turbine mechanism, 7. blowoff valve, 8. gap, 9. dewatering device, 10. exhanst gas outlet, 11. back purge systems.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The utility model provides a kind of coal-fired boiler smoke purifying device, as shown in Figure 1, comprise inner core 1 and urceolus 2, inner core 1 is arranged on the inner admission line 3 that also passes through of urceolus 2 and is connected with the discharge flue of boiler, and admission line 3 inside are provided with shower 4, and inner core 1 lower sidewalls is provided with equally distributed aperture 5, inner core 1 bottom is provided with turbine mechanism 6, urceolus 2 bottoms are provided with blowoff valve 7, are provided with gap 8 on urceolus 2 middle part sidewalls, and urceolus 2 tops are provided with dewatering device 9 and exhanst gas outlet 10.
During concrete enforcement, admission line 3 is connected with the discharge flue of boiler, and exhanst gas outlet 10 is connected with chimney, and shower 4 is connected with circulating pump in circulating water pool, and gap 8 is connected with oxidation pond.As shown in Figure 2, recirculated water with desulfurizing agent is extracted from circulatory pool by circulating pump, enter in coal-fired boiler smoke purifying device by pipeline, recirculated water through dust-removal and desulfurizing is flowed in oxidation pond by gap 8, in oxidation pond, the calcium sulfite oxidation in recirculated water becomes calcium sulfate, and calcium sulfate is with in recirculated water inflow sedimentation basin and at the bottom of being deposited in pond, recirculated water after clarification flows into mixing pit to be mixed and flows in circulatory pool with the desulfurization slurry that makes, thereby realizes the circulation of water.In the course of work, the flue gas of discharged from coal-fired boiler enters inner core 1 by admission line 3, admission line 3 inside arrange shower 4, the recirculated water that contains desulfurizing agent is sprayed onto in admission line 3 flue dust to be contacted with recirculated water with sulfur dioxide merge by circulating water pool and carries out the rough dusting desulfurization, the recirculated water that sprays is flow in urceolus 2 by inner core 1, be provided with gap 8 on urceolus 2 middle part sidewalls, constantly enter recirculated water in urceolus 2 by gap 8 discharged in oxidation pond.The gap 8 that arranges on urceolus 2 sidewalls can make the recirculated water of urceolus 2 inside remain on fixing liquid level.the latter half of inner core 1 immerses in the interior recirculated water of urceolus 2, recirculated water further sees through the aperture 5 of inner core 1 bottom and the space of turbine mechanism 6 and enters inner core 1 the inside, inner core 1 bottom is inverted cone-shaped structure, be arranged on turbine mechanism 6 High Rotation Speeds in exit, inverted cone-shaped structure lower end, flue gas through the rough dusting desulfurization is entered in inner core 1 and is further circulated in recirculated water by admission line 3, the whirlpool collision that High Rotation Speed by turbine mechanism 6 produces makes flue gas fully contact fusion with recirculated water, differential segmentation diving through aperture 5 forces recirculated water to wash fully flue gas again, complete further dust-removal and desulfurizing, flue dust deposits to the bottom of urceolus 2 downwards in the lotion process, urceolus 2 bottoms are also inverted cone-shaped structure, dust deposition is regularly discharged by blowoff valve 7 to certain the time, the preferred butterfly valve that adopts of blowoff valve 7.Flue gas through further dust-removal and desulfurizing rises arrival dewatering device 9 on the space between inner core 1 outer wall and urceolus 2 inwalls, the preferred turbo-centrifugal drier that adopts of dewatering device 9, by the High Rotation Speed effect of drier the moisture in flue gas is thoroughly removed and finally by exhanst gas outlet 10 discharged in chimney.Dewatering device 9 is meeting residual smoke powder after the work certain hour, on urceolus 2 tops, is provided with back purge system 11, and anti-cleaning device 11 is connected regularly dewatering device 9 is cleaned with running water.
