The specific embodiment
Referring to Fig. 1～8, the utility model is provided with pedestal 1, dust-laden sewage pipe 2, water seal tank 3, block 4, resistance konisphere 5, deflector 6 and 7, bracing frame 8, annular conduit 9, jet pipe 10, flue gas inlet tube 11, cylindrical shell 12, inner core 13, baffle 14, brace rod 15, gas approach 16, larynx neck 17 and the saturated chamber 18 of flue gas etc.
Flue gas inlet tube 11 forms an angle in the horizontal direction with cylindrical shell 12, makes air intake form eddy flow downwards, and bracing frame 8 is located at cylindrical shell 12 outsides.Be provided with at least 1 block 4, at least 1 circle resistance 5, at least 1 baffle 14 of konisphere and brace rod 15 at inner core 13 inwalls, block 4, resistance konisphere 5, baffle 14 all are connected with the inwall of inner core with brace rod 15.Flue gas is further purified by block in the inner core 4 and resistance konisphere 5.Establish tube for removing ash 20 in dust mouth, cylindrical shell bottom.
Form ring smoke chamber 19 between cylindrical shell 12 and the inner core 13, the bottom is led in portion from it, and the flue gas that comes from boiler enters smoke chamber 19 by flue gas inlet tube 11 under air-introduced machine (referring to Fig. 9) effect, draw from inner core 13 tops again.Flue gas enters smoke chamber 19 and forms the inertia eddy flow, and the water of each jet pipe 10 ejection forms water smoke and takes away grit, the SO in the flue gas
2Absorbed by water smoke, under inertia and gravity effect, land along cylindrical shell 12 inwalls.
Flue gas after being purified is discharged through inner core 13 tops under the air-introduced machine effect, in its process through block in the inner core 13 4 and resistance konisphere 5, the grit that purifies in the flue gas is kept off back, the small part grit is with purifying flue gas enters inner core 13 by resistance konisphere 5 middle part and top, speed slows down, the water smoke that contains grit flow to water seal tank 3 then to falling into the saturated chamber 18 of flue gas.
Referring to Fig. 9, the flue gas that oil burning boiler 91 produces enters desulfation dust-extraction device 93 through flue 92, and flue gas after being purified 94 is introduced chimney 97 by air-introduced machine 95 by underground flue 96 and discharged, and the dust of being taken away by water mixes liquid after treatment, the clear water reuse.The dust-laden sewage of discharging from desulfation dust-extraction device enters sedimentation basin 99 through outlet pipe 98, and the treating apparatus of forming through two-stage clear water reserviors 910 and 911, Calcified pond 912, milk of lime pump 913, agitator 914, water pump 915 is handled again.But the clear water of clear water reserviors 911 by water pump 915 through water pipe 916 reuses.
Calcified pond 912 is preferably the milk of lime pond, and adds medicinal cupping, preferably adds an amount of lime or sodium carbonate (Na in clear water reserviors 910 and 911
2CO
3), regulating pH is 6～9, clear water promptly is recycled, and the whole dust-removal system operating cost is reduced, and eliminated secondary pollution.
The flue gas that enters the saturated chamber 18 of flue gas from the smoke chamber 19 bottoms state that reaches capacity produces sedimentation, SO in the flue gas at this some dust
2With nitrogen oxide etc. by the water smoke washing, absorb.When the flue gas after saturated entered the saturated chamber 18 of flue gas, flue gas quickened gradually, and at larynx neck 17 places, the flue gas acceleration reaches peak, and dust-laden particle and water smoke form turbulent flow, obtain the fullest washing, and then flue gas enters inner core 13 through gas approach 16 and spread.At this moment, the sub-water content of the grit in the flue gas reaches capacity SO
2Fully absorbed last grit and SO by water smoke
2Water droplet is discharged from dust-laden sewage pipe 2, and under the compressed air effect of tube for removing ash 20 it is poured in the water seal tank 3.
After tested, the utility model embodiment can reach following major parameter.
