Description

A kind of cyclone dust collectors that are beneficial to the granule sedimentation
Technical field
The utility model relates to the cyclone dust collectors field, particularly relates to the thoroughly cyclone dust collectors of growth form of a kind of efficiency of dust collection height, dedusting.
Background technology
Cyclone dust collectors are devices that the centrifugal force that utilizes dust-contained airflow to rotate to produce separates grey grit and capture from gas, compare with sack cleaner, fiber bag precipitator, electrostatic precipitator, desulfurizing dust-collector, the advantage such as simple in structure with it, that volume is little, it is easy to maintenance to make, efficiency of dust collection is comparatively desirable becomes one of at present main cleaner.Be widely used in factory's kiln gas dedusting, boiler dust remover and factory's dust removal by ventilation etc., how improving dust removal efficiency in cyclone cleaner is the problem that current dedusting industry need to solve.
During cyclone dust collectors work, when dusty gas enters in the spiral case from air inlet with higher speed, air-flow will become circular motion by rectilinear motion, and make progress, flows downward.Stopped by top cover when the part in the swirling eddy rotates up and return, and the overwhelming majority is under the screw along the shell inwall in the swirling eddy, flows towards cone, rotational gas flow in forming.Because much larger times of the density ratio air of grit, therefore the grit of rotation is subjected to the effect of centrifugal acceleration doing in the circular motion with gas, will separate from air-flow and get rid of to the spiral case inwall, drops in the cone cinder catcher and discharges through ash discharging hole.
The factor that affects dust removal efficiency in cyclone cleaner is a lot ,The degree of depth of blast pipe, the length of cone and cone angle size are larger on the impact of deduster efficiency of dust collection, and exhaust duct inserted shallow, easily caused the air inlet dust-contained airflow directly to enter dust flue, and had increased the possibility that the mixing of dust secondary goes out, and affected efficiency of dust collection; When too short the and cone angle of cone length was excessive, the sedimentation time of dust in settlement barrel was shorter, is unfavorable for the sedimentation of dust, equally also affects the efficiency of dust collection of deduster.
The utility model content
The technical problem that the utility model mainly solves provides a kind of cyclone dust collectors that are beneficial to the granule sedimentation, can solve the dust secondary mixing that exists in the existing deduster and go out and short problem of the sedimentation time of dust in settlement barrel.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of cyclone dust collectors that are beneficial to the granule sedimentation are provided, comprise: blast pipe, the cone cinder catcher, buffering hopper and cylindrical shell, comprise in the described cylindrical shell: exhaust duct, cyclone and cone settlement barrel, be fixed with the spiral stream guidance blade on the described exhaust duct, described cinder catcher lower end is provided with ash discharge, described blast pipe is located at cyclone one side and communicates with cyclone, described cyclone lower end connects conical settlement barrel and communicates with cyclone, be provided with the buffering hopper of back taper between described settlement barrel and the cinder catcher, described cone settlement barrel length lengthens and the cone angle size is made as 20 ° ~ 25 °.
In preferred embodiment of the utility model, described exhaust duct lower end extends the lowermost end of cyclone.
In preferred embodiment of the utility model, be lined with basalt and Ceramic Composite dope layer on the described cylinder inboard wall.
The beneficial effects of the utility model are: the utility model has increased the time of staying of air-flow in cyclone, and prevented that the inside part grit from wrapping up in in/out air tube, it is complete to be conducive to short grained sedimentation, thereby has improved the efficiency of dust collection of equipment, and dust removing effects is more thorough.
Description of drawings
Fig. 1 is a kind of structural representation that is beneficial to cyclone dust collectors one preferred embodiment of granule sedimentation of the utility model;
The mark of each parts is as follows in the accompanying drawing: 1, blast pipe, 2, cylindrical shell, 21 exhaust ducts, 211, the spiral stream guidance blade, 22, cyclone, 23, the cone settlement barrel, 3, the taper cinder catcher, 31, ash discharging hole, 4, the buffering hopper, 5, composite coating layer.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
See also Fig. 1, the utility model embodiment comprises: blast pipe 1, cone cinder catcher 3, buffering hopper 4 and cylindrical shell 2, comprise in the cylindrical shell 2: exhaust duct 21, cyclone 22 and cone settlement barrel 23, be fixed with spiral stream guidance blade 211 on the exhaust duct 21, cinder catcher 3 lower ends are provided with ash discharging hole 31, blast pipe 1 is located at cyclone 22 1 sides and communicates with cyclone 22, cyclone 22 lower ends connect conical settlement barrel 23 and communicate with cyclone 22, cone settlement barrel 23 length lengthen and the cone angle size is made as 20 ° ~ 25 °, increased the time of staying of air-flow in cyclone 22, it is complete to be conducive to short grained sedimentation, and the gas that is rotated down gently is transformed into turn back rotation upwards, thereby dust removing effects is improved.
Further, be provided with the buffering hopper 4 of back taper between settlement barrel 23 and the cinder catcher 3, reduced the back mixing of settlement barrel 23 and the generation of the secondary dust phenomenon that lower ash ring produces.
Further, exhaust duct 21 lower ends extend the lowermost end of cyclone 22, have prevented that the inside part grit from wrapping up in in/out air tube, have improved the efficiency of dust collection of equipment, and dust removing effects is more thorough.
Further, be lined with basalt and Ceramic Composite dope layer 5 on cylindrical shell 2 inwalls, strengthened corrosion resistant and the anti-wear performance of cylindrical shell 2 inwalls, prolonged the service life of equipment.
Be different from prior art, the utility model has been done further improvement to its structure on traditional cyclone dust collectors basis: (1) cone settlement barrel 23 length lengthen and adopt 20 ° ~ 25 ° small-angles, increased the time of staying of air-flow in cyclone 22, it is complete to be conducive to short grained sedimentation, and the gas that is rotated down gently is transformed into turn back rotation upwards, thereby dust removing effects is improved; (2) exhaust duct 21 lower ends to cyclone 22 bottom, prevented that the inside part grit from wrapping up in into exhaust duct 21, improved the efficiency of dust collection of equipment, dust removing effects is more thorough.
