Abstract
The utility model relates to a double-layer cyclone dust collector which comprises a dust collector outer wall. A cone airflow downward chamber is formed by the dust collector outer wall. The upper end of the dust collector outer wall is provided with a flue gas inflowing passage. The flue gas inflowing passage is connected with the airflow downward chamber. The bottom of the airflow downward chamber is provided with an ash collection hopper. An inner cylinder wall is also arranged inside the airflow downward chamber. The inner cylinder wall is connected with a top cover of the cyclone dust collector outer wall. The inner cylinder wall separates the airflow downward chamber from an airflow upward chamber. The upper part of the airflow upward chamber is provided with an exhaust pipe. In the utility model, the inner cylinder wall is added, so that the removable size of particles is reduced, the influence generated when the separated particles enter flue gas again is reduced, the dust collecting efficiency is greatly improved, and the application range of the cyclone dust collector is expanded.
Description
Technical field
The utility model relates to a kind of dust arrester, is applicable to that metallurgy, electric power etc. need the field of flue gas, tails dedusting, particularly a kind of double-deck cyclone dust collectors.
Background technology
Cyclone dust collectors are classes of dust arrester.Dust removal mechanism is that dust-contained airflow is rotated, and separates from air-flow and captures in wall by means of centrifugal force depositing dust grain, relends and helps the gravity effect to make grit fall into ash bucket.Common cyclone dust collectors are made up of simplified, cone and air inlet and exhaust piper etc.But, owing to be detained on the cyclone separator barrel powder layer arranged, and barrel is comparatively smooth under particle rubbing action year in year out, the dust granules that part has been separated from flue gas turns under the gas effect of moving down in the deduster inward turning can reenter flue gas, inboard by the reason of the flue gas that directly rebounds back with the part particle at barrel, can cause the overall efficiency of dust collection of cyclone dust collectors to descend.Simultaneously, because common cyclone dust collectors are in the process of work, downdraught and updraft directly cross, and cause cyclone dust collectors on the low side for small size particle removal efficient, have influenced the range of application of cyclone dust collectors.
Summary of the invention
In order to overcome the defective of above-mentioned prior art, the purpose of this utility model is to provide a kind of double-deck cyclone dust collectors, have efficient, energy-conservation, safety, characteristics such as easy.
In order to achieve the above object, the technical solution of the utility model is:
A kind of double-deck cyclone dust collectors, comprise deduster outer wall 1, deduster outer wall 1 constitutes the downward chamber 3 of air-flow of taper, the upper end of deduster outer wall 1 is provided with flue gas flow channel 2, flue gas flow channel 2 links to each other with the downward chamber 3 of air-flow, the bottom of the downward chamber 3 of air-flow is provided with flue-dust retainer 4, and 3 inside, the downward chamber of air-flow also are provided with inner tube wall 5, and inner tube wall 5 is connected with cyclone dust collectors outer wall top cover.Inner tube wall 5 is separated downward chamber 3 of air-flow and the air-flow chamber 6 that makes progress mutually, and air-flow 6 tops, chamber that make progress are provided with blast pipe 7.
The air guide bar that described inner tube wall 5 is equidistant helical arrangement constitutes.
The air guide bar camber of described inner tube wall 5, windward side air guide bar are to center curvature, and leeward side air guide bar is done crooked slightly to the downward chamber 3 of air-flow.
The utility model has the advantages that:
1, cyclone dust collectors is divided into chamber 6 on the 3 gentle flow directions of the downward chamber of air-flow, has prevented from directly to discharge, make fine particle bump barrel or inner tube wall 5, improved efficiency of dust collection from blast pipe 7 than fine particle.
2, cyclone dust collectors are divided into chamber 6 on the 3 gentle flow directions of the downward chamber of air-flow, the particle that reenters flue gas from outer tube wall 1 can not discharged easily, still can in this deduster, obtain removing, improved efficiency of dust collection.
3, inner tube wall 5 dust granules that carries in the flue gas that moves upward in the chamber 6 for air-flow makes progress provides the bump plane, has improved efficiency of dust collection.
4, inner tube wall 5 has the air-flow guide effect, and simultaneously inner tube wall 5 is non-separates chamber on the 3 gentle flow directions of the downward chamber of air-flow 6 fully, has improved efficiency of dust collection so increase under the unconspicuous situation by resistance at flue gas.
5, this utility model is simple in structure, and operation is convenient, is suitable for the transformation of traditional cyclone dust collectors.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of inner tube wall 5.
Fig. 3 is the structural representation of inner tube wall 5 air guide bars.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
With reference to accompanying drawing 1, a kind of double-deck cyclone dust collectors, comprise deduster outer wall 1, deduster outer wall 1 constitutes the downward chamber 3 of air-flow of taper, the upper end of deduster outer wall 1 is provided with flue gas flow channel 2, and flue gas flow channel 2 links to each other with the downward chamber 3 of air-flow, and the bottom of the downward chamber 3 of air-flow is provided with flue-dust retainer 4,3 inside, the downward chamber of air-flow also are provided with inner tube wall 5, and inner tube wall 5 is connected with cyclone dust collectors outer wall top cover.Inner tube wall 5 is separated downward chamber 3 of air-flow and the air-flow chamber 6 that makes progress mutually, and air-flow 6 tops, chamber that make progress are provided with blast pipe 7.
With reference to Fig. 2, the air guide bar 8 that described inner tube wall 5 is equidistant helical arrangement constitutes.
With reference to Fig. 2, Fig. 3, air guide bar 8 cambers of described inner tube wall 5, windward side air guide bar are to center curvature, and leeward side air guide bar is done crooked slightly to the downward chamber 3 of air-flow.
Operation principle of the present utility model is:
Ash-laden gas enters the downward chamber 3 of air-flow by flue gas flow channel 2, and rotation moves downward.Flue gas turns under by inner tube wall 5 windward side effects in the downward chamber 3 of air-flow, force flue gas between cyclone dust collectors outer wall 1 and inner tube wall 5, to move, make the particle in the flue gas have more opportunity to strike deduster outer wall 1 and inner tube wall 5, thereby reach the purpose of separation.Reenter flue gas at deduster outer wall 1 because of the smoke movement influence, in the downward chamber 3 of air-flow, can only move downward at the inboard particle of barrel with the part particle by the flue gas that directly rebounds back along flue gas, increased the chance of these particle collision barrels simultaneously, prevented from directly to enter ascending air and directly taken out of deduster, so efficiency of dust collection is improved.Flue gas is subjected to the 1 lower taper effect of deduster outer wall to begin to transfer to below the downward chamber 3 of air-flow to move upward, and enters the air-flow chamber 6 that makes progress.Flue gas rotation moves upward in air-flow makes progress chamber 6, thereby remaining particle is still had an opportunity to strike inner tube wall 5 and removed in this process, has reached the purpose of further raising efficiency of dust collection.Treated flue gas is discharged these bitubular wall cyclone dust collectors by blast pipe 7, and isolated particle is cleared after the effect lower edge of gravity deduster outer wall 1 enters flue-dust retainer 4.
