Description
Technical field
Carry out gas-solid two-phase separation technology field in the fluid field of force of the utility model genus rotation, be applied to environmental protection and gather dust, select the fine dust in the powder classification process to capture.
Background technology
Reversible type list air outlet cyclone separator is flowed in cutting of domestic current technology, owing to have " core forced vortex ", " short-circuit flow ", " secondary back-mixing " three birth defects, it is bigger that ubiquity the pressure loss, and separative efficiency is not high, is difficult to capture the shortcoming of the following low concentration dust of 15 μ m.
In order to overcome these three birth defects of traditional cyclone separator, the worker has done all effort both at home and abroad, more representational is " adjustable pair of air outlet cyclone separator of flow-guiding mouth " patented technology (ZL00265063.0, patentee Ni Wen dragon, Ni Zhenhong), Fig. 5 is adjustable pair of air outlet cyclone separator of a flow-guiding mouth fundamental diagram, this technology increases a following air outlet 18b than single air outlet cyclone separator, reflection cone 17b also increases an adjustable guiding device 16b of flow-guiding mouth aperture and last air outlet 14b, following air outlet 18b just joins, thereby avoided the generation of core forced vortex, make the pressure loss reduce more than 30%, simultaneously because of having avoided " short-circuit flow " and " secondary back-mixing ", separative efficiency is improved, but in the dust (flue dust) less than the particulate of 10 μ m, arresting efficiency is difficult to very high, usually need add thereafter join investment and operating cost higher bag gather dust or electricity gathers dust.
Summary of the invention
The utility model purpose is to provide a kind of dual regulation diffluence pass formula combination trap that can capture less than the fine dust of 10 μ m: under the condition that does not significantly increase the existing technology cyclone separator pressure loss and operating cost, adopt the shunting serial connection and the part circulation of two-stage low-resistance separator, significantly improve cyclone separator and capture the fine powder ability.
The technical scheme that the utility model adopted is: dual regulation diffluence pass formula combination trap is made up of air-out cyclone separator, Purge gas flow control valve, dust concentration tester, two air outlet cyclone separator, blower fan on the following air intake of diffluence pass position and flow dual regulation.Cyclone separator is made of tangent air inlet of cylindrical tube, downside and two blast pipes on cylindrical tube top, central authorities' blast pipe and tangential exhaust outlet form diffluence pass in inner barrel, central authorities' blast pipe and Purge gas flow control valve, blower fan composes in series Purge gas emptying passage, effectively controls the Purge gas flow by flow control valve; Tangential exhaust outlet and two air outlet cyclone separators, blower fan, following air inlet serial connection constitutes the circulation canal that separate the second level.The central blast pipe of cyclone separator is installed the shunting regulating sleeve outward and is cooperated with the blast pipe concentric gap, shunting regulating sleeve two bottom sides and two tooth bars are rigidly connected, two tooth bars respectively with the gears engaged of rotating synchronously around fixed axis, by rack-and-pinion transmission lift adjustment sleeve end opening position, promptly change the diffluence pass physical location, to regulate the ratio of purifying gas flow and enrichment dust throughput.
System is work like this: dusty gas is tangentially entered by air inlet under the cyclone separator, in rotating up process, wall is hit in thick grit centrifugation, drop down onto the separate lock air-valve, be enriched in the periphery than fine dust, the internal layer purifying gas flow is shunted in central blast pipe lower end with peripheral enrichment dust air-flow, purifying gas flow is from central blast pipe, the Purge gas flow control valve, the dust concentration tester, air-introduced machine is discharged, enrichment dust air-flow is discharged from tangential exhaust outlet, enter two air outlet cyclone separators again, the following fine dust of 10 μ m collides and the increase of adhesive aggregation probability because of mutual under enrichment state, more easily be captured, discharge through the control of dust air valve, gas is through reflection cone behind the double purification, the flow-guiding mouth of guide shell, two air outlets up and down, circulating fan is discharged, the most of inlet from the recirculation of secondary separation air-flow returned air inlet under the cyclone separator, enter next separating cycle with pending dusty gas, so can ignore the residual dirt load loss in the first class purification air-flow of back, the total discharging of system is the residual dirt capacity value of Purge gas in the central blast pipe, so the total dust-collecting efficiency of secondary significantly improves than one-level.
The beneficial effects of the utility model are:
1. adopt two kinds of low resistance cyclone separator shunting serial connections and part circulation, dust-contained airflow in cyclone separator after first order Purge gas shunting, the following fine dust of 10 μ m is mutually collision and the increase of adhesive aggregation probability and effectively captured under enrichment state, so the total dust-collecting efficiency of secondary significantly improves than one-level; Again because first order cyclone separator does not have buffer brake loss and core forced vortex, the pressure loss will be about 35% of a conventional separators, second level separator adopts two air outlet cyclone separators, its pressure loss is 70% of a conventional separators, thereby the addition of the two-stage pressure loss does not significantly increase than conventional separators.
2. adopt the dual regulation method to realize the adjusting of diffluence pass Purge gas discharge capacity and residual dirt capacity value: 1. turn Purge gas flow control valve is directly regulated flow; 2. by the rack-and-pinion adjusting device, the shunting regulating sleeve that lifting is coaxial with blast pipe changes the diffluence pass physical location, thereby the residual dust concentration of Purge gas is effectively controlled.
