Abstract
The utility model relates to a microwave desulfurization dust-removing device, which is composed of an air inlet pipe, a discharge pipe, an air exhaust pipe and a desulfurization dust-removing part. The air inlet pipe and the discharge pipe are arranged at the lower part of the utility model. The air exhaust pipe is arranged at the upper part of the utility model. The desulfurization dust-removing part is arranged at the middle part of the utility model. The desulfurization dust-removing part comprises an insulation chamber, a decontamination chamber, etc. The outer wall of the decontamination chamber is provided with a high voltage power. The inner of the decontamination chamber is suspended with an electric corona plate. The desulfurization dust-removing part also comprises a microwave radialization chamber. The outer wall of the microwave radialization chamber is provided with a microwave generator. The utility model has high dust removing effect, which can effectively avoid the secondary pollution.
Description
The utility model belongs to the environmental protection field, is specifically related to utilize microwave technology to remove a kind of deduster of harmful substance in the industrial combustion waste gas.
Mainly contain SO in the industrial waste gas
2And NO
xEtc. harmful substance, at present, a lot of to the processing method and the equipment of burnt gas both at home and abroad, as warm formula electric cleaner, wet process of FGD etc., but there is the handling problem of etching apparatus, mud and sewage in the former, and latter's flue gas after desulfurization is by humidifying cooling, be unfavorable for the diffusion of chimney exhaust, white cigarette easily takes place simultaneously, if liquid waste processing is improper, easily causes secondary pollution.
The purpose of this utility model proposes a kind of efficiency of dust collection exactly than the prior art height, can avoid the microwave deduster of secondary pollution effectively.
The utility model utilizes microwave radiation source, makes to enter deduster inside and contain SO
2And NO
xPhysicochemical change takes place in waste gas in the microwave irradiation process, finally form the solid sulphuric acid particle, is captured by deduster.Waste gas after the processing becomes clean gas and enters atmosphere from outlet, and the recyclable comprehensive utilization again of solid acid particle.
This deduster partly is made of the dust-removal and desulfurizing at bottom air inlet pipe, discharge pipe and top blast pipe and middle part, dust-removal and desulfurizing partly comprises insulation chamber, clean room, microwave radiation chamber, clean room's outer wall is provided with high voltage source, corona plate has been hung in inside, microwave radiation chamber outer wall is equipped with microwave generator, is placed with a lateral isolation suspension rod between insulation chamber and the blast pipe.
The high voltage source of outside, clean room, voltage are 75000V, microwave (0.24-0.33 μ M), and frequency is 0.3-1.0MHZ, works as 10000M
3Combustion product gases enters in the deduster (SO wherein
2About 9000PPM, NO
xAbout 1800PPM), 4-5 is after second in circulation, and testing result is: SO
2Be about 450PPM, NO
x60PPM improves 40% than prior art.
Owing to form the solid sulphuric acid particle and it is concentrated comprehensive utilization, avoided secondary pollution and, reached desulfurization and dedusting effect preferably the corrosion of equipment.
Below in conjunction with accompanying drawing in detail the utility model is described in detail.
Accompanying drawing is a schematic diagram of the present utility model.
Among the figure, 1-cleaned air discharge pipe, 2-insulated hanging pole, the 3-chamber of insulating, the 5-of 4-clean room microwave radiation chamber, 6-air inlet pipe, 7 outlets, 8-microwave generator, 9-high voltage source 10-corona plate.
When containing SO
2And NO
xWaste gas enter in the deduster from air inlet pipe 6, under the double action of static and microwave radiation, become comparatively clean air to enter atmosphere exhaust-gas treatment, and SO from top
2Then become solid acid particle dust and fully utilize or handle, thereby reach effective desulfurization and dedusting, prevent the purpose of secondary pollution from the outlet discharge.
