Abstract
The invention discloses a cyclone dust collector with a double ash discharge structure, and belongs to the technical field of environment friendly separation of dust. The cyclone dust collector comprises an air inlet pipe, an exhaust pipe, a cylindrical cyclone and a conical ash collector, wherein the air inlet pipe and the exhaust pipe are arranged on one side and at the top end of the cyclone respectively; and the conical ash collector is arranged at the lower end of the cylindrical cyclone. According to the invention, a small cone and a small cylinder are additionally arranged at the bottom of the ash collector, and the diameter of the upper end of the small cone is designed to be smaller than that of the small cylinder, so that an annular gap is formed between the small cone and the small cylinder. Through the method, the cyclone dust collector can ensure that most of dust is discharged from the annular gap firstly, and small dust is discharged from the small cone, so that the double ash discharge structure is formed, the quantity of dust entering vortexing and turbulence from the bottom of the cone is reduced, dust taken away by secondary fly ash is reduced, the dust removal efficiency of the cyclone dust collector is improved, and a better environmental protection effect is achieved.
Description
Technical field
The present invention relates to the environment-friendly type separation technology field of dust, particularly relate to a kind of cyclone dust collectors of double grey structure.
Background technology
Along with people's is to the attention of environmental quality, and discharging is all polluted, reduces to new technology, new technology, new equipment to reduce be the target research and development.Deduster is exactly a kind of reduction of discharging, oligosaprobic product.Be used for the atmosphere dedusting at present and mainly contain three types of dedusting technologies: electric precipitation, cloth bag dust removal by filtration and cyclone dust removal.Receive people's favor owing to cyclone duster structure is simple, five actuating units drive, can adapt to advantages such as adverse circumstances, investment and operating costs such as high temperature, high pressure and the medium that is corrosive are few.Cyclone dust collectors are to be utilized in the rotating cylinder air-flow of rotation at a high speed, make grit produce centrifugal and realize separating of dust and air-flow, still existing cyclone dust collectors to the deposition capability of fine powder a little less than, cause to be prone to secondary dust phenomenon.
The secondary dust is meant that separating the particle that deposits on the wall is taken away by the gas that upwards flows, and enters into clean gas flow and discharges the phenomenon of deduster, has a strong impact on the efficiency of dust collection of cyclone dust collectors.
The factor that influences the cyclone dust collectors reentrainment of dust has a lot, and wherein principal element has: eddy current that the outer eddy flow of the fine powder of cone surface deposition, the cone of flowing through produces when cone base upwards reverses and conical section tangential velocity increase the turbulent flow that produces.Secondary dust phenomenon all exists at the cylinder and the cone of cyclone dust collectors, but the secondary dust of conical section is the most serious, and the dust entrainment that causes accounts for from the overwhelming majority of blast pipe carry over total amount.Cone base is the enrichment region of fine powder, also is the pilosity district of eddy current and turbulent motion simultaneously, adds the spatial constraints of cone base, and this zone just must become the serious zone of secondary dust.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of cyclone dust collectors of double grey structure, can reduce the discharge capacity that existing cyclone dust collectors cone base secondary is raised wind, makes to discharge gas cleaning more.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: the cyclone dust collectors that a kind of double grey structure is provided; Comprise: air inlet pipe, blast pipe, cylindrical cyclone and conical cinder catcher, said air inlet pipe and blast pipe are located at a side and the top of cyclone respectively, and said cinder catcher is located at cylindrical cyclone lower end; Below said cone cinder catcher, set up a small cylinder, and be provided with a small cone body in small cylinder inside.
In preferred embodiment of the present invention, the up big and down small and upper end bore of the bore of said small cone body forms the annulus less than the cylinder bore between said small cone body and the small cylinder.
In preferred embodiment of the present invention, the height of said small cone body and small cylinder is the same, accounts for 1/4 ~ 1/3 of the conical cinder catcher height in upper end.
The invention has the beneficial effects as follows: the present invention improves on the architecture basics of traditional cyclone dust collectors; Making most of dust drop in the annulus discharges; Another fraction dust is discharged from little centrum; Thereby formed double grey structure, reduced the Dust Capacity that cone base enters into eddy current and turbulent flow, reduced the dust of taking away because of the secondary dust to greatest extent.
Description of drawings
Fig. 1 is the structural representation of cyclone dust collectors one preferred embodiment of a kind of double grey structure of the present invention;
Fig. 2 is the structure for amplifying sketch map of the present invention to the cyclone dust collectors improvement part;
The mark of each parts is following in the accompanying drawing: 1, blast pipe, 2, air inlet pipe, 3, cylindrical cyclone, 4, conical cinder catcher, 5, small cylinder, 6, small cone body, 7, the annulus, I, improvement part, 8, go up rotational gas flow, 9, rotational gas flow down.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1 and Fig. 2; The embodiment of the invention comprises: air inlet pipe 2, blast pipe 1, cylindrical cyclone 3, conical cinder catcher 4 and improvement part I; Air inlet pipe 2 and blast pipe 1 are located at a side and the top of cyclone 3 respectively, and cinder catcher 4 is located at cylindrical cyclone 3 lower ends, and improvement part I comprises: small cylinder 5 and small cone body 6; Small cylinder 5 is positioned at conical cinder catcher 4 bottoms, and is provided with a small cone body 6 in small cylinder 5 inside.
Further, the up big and down small and upper end bore of the bore of small cone body 6 forms annulus 7 less than cylinder 5 bores between small cone body 6 and the small cylinder 5, make most of dust from slit 7, discharge.
Further, small cone body 6 is the same with the height of small cylinder 5, accounts for 1/4 ~ 1/3 of conical cinder catcher 4 height in upper end, helps the deposition of dust.
Operation principle of the present invention: when dusty gas arrives cinder catcher 4 bottoms from blast pipe 2 behind circulator 3; Most of dust is by discharging in the annulus 7; And most of rotational gas flow 9 down enters in the roundlet centrum 6; The air-flow that rotates in the small cone body 6 can form the last rotational gas flow 8 upwards of turning back, and discharges from blast pipe 1.
Be different from prior art; The present invention sets up a small cone body 6 and a small cylinder 5 in the cinder catcher bottom; Wherein the upper end bore of small cone body 6 is arranged to the bore less than cylinder 5, make to form annulus 7 between the two, thereby most of dust is discharged earlier from annulus 7; Improve the efficiency of dust collection of cyclone dust collectors, reach better environment protecting.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
