Description

Unit-combined multiple multivortex mechanical collector

The utility model is the deduster that is combined by one or more unit modules.Unit module has wherein adopted gravitational settling, inertia to stop, stream multiple dust removal mechanisms such as detention, centrifugal force, is inertial settling dedusting and the sub-dedusting two-stage of whirlwind one on the structure.It is suitable for aspects such as industrial smoke dedusting, dust removal by ventilation and air-transport system gather dust.

Common multicyclone is vertically to arrange whirlwind, after dusty gas enters the admission space on the sub-top of whirlwind, distributes air-flow for each whirlwind, all will pass through whirlwind regardless of different kinds of the grit in the dusty gas.Move to grit (the especially slightly grit) rotation at a high speed on the sub-internal face of whirlwind, not only make the wearing and tearing of whirlwind, and cause the grit pulverizing that efficiency of dust collection is exerted an influence.Also there are problems such as distribution of air flow inequality, crossfire, dust secondary back-mixing in this class deduster handling the bigger occasion of the ash-laden gas scale of construction.

Also have a class multicyclone, adopt whirlwind from top to bottom tilting, utilize the admission space of the sub-hull outside of whirlwind, carry out inertial settling and gather dust.This deduster is than increasing on the aforementioned performance of precipitator, and undesirable part is: gathering dust of inertial settling can not be imported ash bucket at once, and it is washed into the sub-import of whirlwind during with air motion, causes the dust content that enters back whirlwind to increase.

The purpose of this utility model provides a kind of novel deduster, and it will organically combine inertial settling dedusting and the sub-dedusting of whirlwind.Its technological approaches is the sub-admission space of common whirlwind tilting, utilizes the whirlwind subshell to do the inertia block body, forms to utilize gravitational settling, inertia to stop, stream the dedusting space of dust removal mechanisms such as detention, is called for short inertial settling dedusting space.It is used for removing the thick grit that contains gas, reduces the entrance concentration and the thick dirt composition that enter whirlwind.Select for use higher the cutting of efficiency of dust collection to flow reversible type whirlwind, and the configuration odour seal is used for final dusting, the thin dirt composition in the removal dusty gas.Adopt unit module, can carry out one or more unit module combinations, the air current composition problem when the solution gas flow is big according to ash-laden gas scale of construction size.

Design of the present utility model according to the principle of Dual-Phrase Distribution of Gas olid body motion, rationally is provided with the internal structure of unit module body, constitutes deduster by external pipe each unit module that is connected in parallel.Unit module primary structure schematic diagram is referring to accompanying drawing 1, and the figure acceptance of the bid is kept the score and is not expressed as: 1. air inlet; 2. admission space; 3. whirlwind; 4. lower clapboard; 5. trapping tube; 6. the whirlwind ash bucket that gathers dust; 7. inspection opening; 8. unloading valve; 9. the inertial settling ash bucket that gathers dust; 10. the sub-import of whirlwind; 11. upper spacer; 12. exhaust outlet; 13. exhaust space.

Its operation principle is: dusty gas is introduced deduster by external pipe, from top to bottom flows into admission space 2. by part 1. air inlets earlier, and thick grit drops on the lower clapboard 3. under air-flow and self gravitation effect.The air-flow of having removed thick grit travels forward, and is subjected to stopping of whirlwind 3. shells, and thick grit is subjected to the inertia force effect to be blocked in the air-flow, and air-flow streams the whirlwind period of the day from 11 p.m. to 1 a.m, and part is got off by whirlwind subshell contact detention than dustshot; Stream centrifugal action part is contacted with sidepiece whirlwind subshell than dustshot, got off by detention.In this space the dust direction of motion of receiving consistent with the primary air direction of motion, lower clapboard has constant slope in addition, making gathers dust successfully flows in the ash bucket 9..On the sub-axial cross section of whirlwind, its entrance location is near near the upper spacer 11., and the sub-bottom of whirlwind is cone, and this just makes the air-flow rate of climb little in the bottom value, avoids the secondary that gathers dust is taken up.The sub-import of whirlwind is the primary air direction dorsad, has strengthened the air-flow effect, makes the dusty gas that only contains than dustshot enter whirlwind.Whirlwind the thin dirt of receiving through 5. secondary separations of trapping tube and conveying, can successfully flow in the ash bucket 6..Because the inertial settling effect, the dust content that enters back row's whirlwind reduces gradually.Gas through twice dedusting is discharged by whirlwind, passes upper spacer 11. and flows into exhaust space 13., is discharged by exhaust outlet 12. then.Porting also can be provided with valve and rise and close and regulating action.The deduster unit module also is provided with inspection opening 7..Airtight performance unloading valve 8. is preferably adopted in the ash bucket bottom.

Operation principle in 1 with reference to the accompanying drawings, unit module is designed to single district or two-region form.Single district unit module is seen accompanying drawing 2.Dusty gas enters a side by a side and discharges.Two-region unit module desirable " V " shape structural configuration is seen accompanying drawing 3, i.e. both sides air inlet, and intermediate exhaust is perhaps fallen " V " shape structural configuration, sees accompanying drawing 4, i.e. both sides exhaust, middle air inlet.

The utility model principal character can sum up following some:

(1) deduster is combined by one or more unit modules, and each unit module is made of admission space, Shi Gangzi, exhaust space, ash bucket etc. again.Be connected in parallel with external pipe between each unit, each unit intake and exhaust can be provided with electrically operated valve or manually-operated gate.

(2) unit module adopts single district to arrange or the two-region layout.Single district is arranged as a side air inlet one side exhaust." V " shape structure that can adopt both sides air inlet intermediate exhaust is arranged in the two-region, can also adopt " V " shape structure of the middle air inlet of both sides exhaust.

(3) admission space of unit module is tilting, and its angle is relevant with the dust characteristic of being removed.The last lower clapboard of admission space and the sub-axis normal of whirlwind.

(4) whirlwind is arranged and is adopted arranged in a straight line or cross arrangement.General employing even number whirlwind arranged in a straight line on flow area, cross arrangement very is disposed in order whirlwind by idol.On the direction of air motion, every row whirlwind can be arranged 3～8.

(5) whirlwind adopts and cuts stream reversible type efficient cyclone, and its import is positioned at admission space top.To single import whirlwind, its import is primary air dorsad.The sub-bottom of whirlwind has the trapping tube, the not external pipeline section of exhaust end.

Use the utility model, have following evident characteristic:

It is compound that gravitational settling, inertia stop, stream multiple dust removal mechanisms such as detention, centrifugal force, the sub-dedusting two-stage of inertial settling dedusting and whirlwind one, and efficiency of dust collection significantly improves, and has enlarged the scope of application of multicyclone dust content; Removed the sub-externally connected exhaust pipe of whirlwind commonly used, dust remover resistance decreases; Air motion is reasonable in the deduster, has played dedusting and has carried the effect of gathering dust; The equipment overall compact, not easy to wear, obstruction, operational management is convenient; Unit module is prepared, processes, transports, installs very convenient; Can set up stand-by unit, carry out not shutdown maintenance, equipment dependability strengthens.
