Abstract

The utility model discloses a kind of double rotational directions cyclone dust collectors, comprise cylindrical shell, lower cone and airlock, cylindrical shell is fixed on lower cone top, lower cone bottom is airlock, helical blade plate is provided with in cylindrical shell, cylinder inboard wall arc-shaped surface is provided with the reverse acting spiral plate contrary with helical blade plate rotation direction, and described lower cone side is provided with tangential admission mouth, and cylindrical shell top is provided with gas outlet.The utility model arranges internal helical blades plate, add flow rotation speed, overcome the decay of rotation, increase centrifugal force, grit more easily throws to wall, cylinder inboard wall arranges reverse acting spiral plate, produce a swirling eddy down, the grit collided with cylinder inboard wall is made to accelerate the down speed of service under backspin airflow function, and can not be taken away by the air-flow risen, two rightabout swirling eddy near interfaces, produce more eddy airstream, make that more tiny grit is separated to get off, efficiency of dust collection improves further.

Description

Double rotational directions cyclone dust collectors
Technical field
The utility model relates to a kind of dedusting treater, is specifically related to a kind of double rotational directions cyclone dust collectors.
Background technology
Cyclone dust collectors produce certain centrifugal force mainly through making gas rotating, make grit and curved surfaces produce collision and lose kinetic energy, fall under gravity separated from the gas, reach the object of dedusting.Cyclone dust collectors traditional in prior art have that following some is not enough: although 1 gas is rotated in dedusting cylinder, limit by structure, after the speed of rotation exceedes certain value, efficiency of dust collection can decline, and centrifugal force can not be enough large; And in air-flow uphill process, rotary speed can decay gradually, so that the trickle grit of part can not throw to wall produce collision, and take away with air-flow.Although 2 dust, under centrifugal action, there occurs collision with wall, some can not be caught separation in time, or is taken away by air-flow, affects efficiency of dust collection.If when 3 gas dust-ladens or certain material concentration higher (the blanking dedusting as the conveying of dilute phase gas), deduster bottom will arrange vane type airlock blanking, because airlock has been in operation return air, is equivalent to deduster bottom and has leaked out, dust collector efficiency is declined to a great extent.4, air inlet is arranged on top, namely increases pipeline height, many consumption materials, turn increases energy consumption.5, bulky take up space large.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art part, provides a kind of double rotational directions cyclone dust collectors, and this deduster efficiency of dust collection is high, good dedusting effect, can effectively separating granular material and dust, and consumptive material, power consumption are few, low cost of manufacture, and it is few to take up an area space.
For achieving the above object, the utility model adopts following technical scheme: a kind of double rotational directions cyclone dust collectors, comprise cylindrical shell, lower cone and airlock, cylindrical shell is fixed on lower cone top, lower cone bottom is airlock, is provided with helical blade plate in cylindrical shell, and cylinder inboard wall arc surface is provided with the reverse acting spiral plate contrary with helical blade plate rotation direction, described cone lower side is provided with tangential admission mouth, and cylindrical shell top is provided with gas outlet.
Based on technique scheme, described helical blade plate is fan leaf type helical blade version.
Based on technique scheme, on described cylinder inboard wall arc surface, be provided with the reverse acting spiral plate that multi-disc is contrary with helical blade plate rotation direction.
Based on technique scheme, described helical blade plate is positioned at cylindrical shell center.
Beneficial effect: 1, because arranging internal helical blades plate, add flow rotation speed, overcome the decay of swirling eddy, increase centrifugal force, grit more easily throws to wall; Cylinder inboard wall arranges reverse acting spiral plate, produce a swirling eddy down, make the grit collided with cylinder inboard wall under backspin airflow function, accelerate the down speed of service, and can not be taken away by the air-flow risen, two rightabout swirling eddy near interfaces, produce more eddy airstream, make that more tiny grit is separated to get off, therefore efficiency of dust collection improves further.2, the return air of deduster bottom airlock is consistent with ascending air, does not therefore affect efficiency of dust collection.3, bottom air inlet, reduces pipeline height and resistance thereof, not only reduces consumptive material but also reduce power consumption.4, deduster size can be reduced, reduce manufacturing cost, reduce and take up an area space.
Accompanying drawing explanation
Fig. 1 is the utility model double rotational directions cyclone dust collectors overall structure schematic diagram;
Fig. 2 is the plan structure schematic diagram of Fig. 1;
Fig. 3 is the air flow direction schematic diagram of the utility model double rotational directions cyclone dust collectors.
Number in the figure: 1 is gas outlet, 2 is helical blade plate, and 3 is reverse acting spiral plate, and 4 is cylindrical shell, and 5 is air inlet, and 6 is hypocentrum, and 7 is airlock, and 8 is ascending air, and 9 is down current, and 10 is vortical flow.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment 1: a kind of double rotational directions cyclone dust collectors, comprise cylindrical shell 4, lower cone 6 and airlock 7, cylindrical shell is fixed on lower cone 6 top, lower cone 6 bottom is airlock 7, in cylindrical shell 4, center is provided with helical blade plate 2, helical blade plate can be fan leaf type helical blade plate, cylindrical shell 1 inwall arc surface is provided with several pieces reverse acting spiral plates 3 contrary with helical blade plate rotation direction, air flow direction figure as shown in Figure 3, inner barrel arranges vane type spiral device, make to accelerate rotary speed in air-flow uphill process, improve centrifugal force; Cylinder inboard wall is arranged reverse acting spiral plate, make barrel produce a swirling eddy contrary with direction, middle part, improve and catch separative efficiency; The flow rotation that middle part dust content is low rises, and the flow rotation that barrel dust content is high declines, between two strands of air-flows, form more eddy airstream, is greatly conducive to improving efficiency of dust collection.
Lower cone 6 side is provided with tangential admission mouth 5, and cylindrical shell top is provided with gas outlet 1.Bottom arranges tangential admission mouth, charge air flow can be made to rotate, separate section large granular materials, bottom air inlet, can also reduce pipeline height and resistance thereof, not only reduces consumptive material but also reduce power consumption, the return air of bottom airlock is consistent with ascending air, can not affect efficiency of dust collection.
