The utility model is characterized in that the outlet of the phase converter is communicated with a foam dust removing device which is communicated with a wet type electrostatic dust removing device, and the outlet of the wet type electrostatic dust removing device is communicated with a chimney. Two-step desulphurization can be carried out through the foam dust removing device and the wet type electrostatic dust removing device, so that the purposes of dust removal and desulfurization for the smoke in a boiler can be achieved with obvious effects; the dust removing efficiency can reach 99.5%, and the percentage of desulfurization is from 75% to 85%. The utility model has the advantages of low manufacturing cost and low operating cost, and is an ideal device for purifying air.
Description
The device that the utility model relates to a kind of dust-removal and desulfurizing, purifies air.
At present, the dust-removing and desulfurizing integrated device of some Industrial Boilers mainly is the product of transforming on the basis of venturi water film deduster, rotating stream tray formula dust-removing and desulfurizing integrated device as Changsha Lu Nan environmental protection equipment factory, the production of the global environmental protection equipment in Changsha factory, its major defect is that efficiency of dust collection is less than 98%, desulfuration efficiency is also lower, also having a kind of is to keep venturi, in tower, install spray and dehumidifying column plate additional, spray adds calcium, desulfuration efficiency can reach more than 75%, but efficiency of dust collection still is lower than 98%, and all unresolved outlet flue gas with water of above scheme problem.
The purpose of this utility model is to provide a kind of dedusting, desulfurized effect higher, cheap, the dust-removing desulfurating apparatus that operating cost is low.
The purpose of this utility model is achieved in that a kind of monolithic devices dust-removing desulfurating apparatus, it comprises phase convertor, the outlet of phase convertor is connected with the foam dust-removing device, and the outlet of foam dust-removing device is connected with wet static dedusting device, and the outlet of wet static dedusting device is connected with chimney.
The foam dust-removing device comprises foam sieve plate and the agitator tank that is connected with the foam sieve plate, and the upper end of agitator tank is connected to lime silo and water pipe, and the lower end links to each other with slag-draining device.Slag-draining device communicates with mortar pool, and mortar pool is connected to speed governing mortar circulating pump.The foam sieve plate is more than 1 layer.The foam sieve plate is 2 layers.Be provided with induced-draught fan between wet cottrell and chimney.
Advantage of the present utility model be following some:
1, the foam dust-removing device is connected with wet static dedusting device, by two step dust-removal and desulfurizings, efficiency of dust collection has been brought up to more than 99.5%, and this device also makes water-soluble SO
2(H
2SO
3) caught by electrostatic precipitator again after by the foam dust-removing device and send the foam dust-removing device back to and participate in desulfurization again, thereby improved desulfuration efficiency, up to 75-85%.
2, since the wet cottrell dust by humidifying, SO2 is become H2SO3 (liquid state) by water-soluble separating, its electric energy power is strengthened, and into speeds up to becoming of pole plate, so cigarette speed can improve 1.5-2.0m/s.
3, be provided with grey water recirculation system, circulating ratio is 1-30, can reduce the desulfurization expense like this.
4, cheap, be example with the 670t/h station boiler, a cost of import equipment is 1-3 hundred million RMB, and about 1,700 ten thousand RMB of a cost of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in detail.
In the accompanying drawings, wherein 1 is phase convertor, and 2 are the foam dust-removing device, and 3 is wet static dedusting device, and 4 is chimney, 5 is the foam sieve plate, and 6 is agitator tank, and 7 is lime silo, and 8 is water pipe, and 9 is slag-draining device, 10 is mortar pool, and 11 are speed governing mortar circulating pump, and 12 is induced-draught fan, and 13 is mortar pool.
As shown in drawings, phase convertor 1 of the present utility model is provided with a plurality of shower nozzles, and water sprays from shower nozzle, with the flue gas moistening and lowering temperature, and ash discharge from here.Behind the ash-laden gas humidification, the dust that particle diameter is big falls into mortar pool 13 by gravity, remaining flue gas then enters in the foam dust-removing device 2 that is connected with phase convertor 1, foam dust-removing device 2 comprises foam sieve plate 5 and coupled logical agitator tank 6, termination lime silo 7 and water pipe 8 on the agitator tank 6, the lower end links to each other with slag-draining device 9, and the lime in the lime silo 7 enters agitator tank 6 with the water of water pipe 8 and stirs mutually, generates CaO, Ca (OH)
2, lime-ash is discharged by slag-draining device 9, falls into mortar pool 10, generates CaO, Ca (OH)
2Fallen on the foam sieve plate 5, with the flue gas generation chemical reaction of coming in, thereby realized desulfurization, foam sieve plate 5 is preferably two layers, and effect is more obvious, and the mortar that falls in the mortar pool 10 passes through speed governing mortar circulating pump 11 with available CaO, Ca (OH)
2Be transported to once more and carry out desulfurization again on the foam sieve plate 5, thereby reduced cost.Enter into the wet static dedusting device 3 further dust-removal and desulfurizings that are connected with its inlet behind flue gas process foam dust-removing device 2 desulfurization and dedustings, and reach the purpose of flue gas dehumidifying, under the attraction of induced-draught fan 12, make dry decontamination flue gas enter chimney 4, and be discharged in the middle of the air, realized the purpose that purifies air.
