Abstract
The utility model provides a cyclone dust removal technology for leading in fresh air current. On the basis of the dust removal principle of the original cyclone dust collector, secondary fresh air without dust is led in the cyclone dust collector from the proper part thereof, and the flow field distribution of the cyclone dust collector is changed and controlled by the secondary fresh air led in so as to achieve the purpose of improving the dedusting efficiency of the cyclone dust collector. On the basis of the structure of original common cyclone dust collector, the outer side of an air outlet pipe is additionally provided with an interlayer sleeve (3), dust-free fresh air is led in through a secondary fresh air intake (4), the fresh air is discharged from the interlayer sleeve to enter a cyclone cylinder, and the original flow field distribution is changed through adjusting the fresh air so as o achieve the purpose of improving the dedusting efficiency. The cyclone dust collector comprises the cyclone cylinder (1), the air inlet pipe (2), the interlayer sleeve (3), the secondary fresh air intake (4), an air outlet pipe (5), an interlayer sleeve transit joint (6), a cone (7) and a dust exhausting opening (8).
Description
Technical field
The utility model relates to environmental protection dedusting technology field and Hydrodynamics Theory, have new distinguished and admirable cyclone dust collectors and be based on hydromechanical theory, utilize the new wind of secondary to change and control the Flow Field Distribution of dusty gas in cyclone dust collectors, to reach the purpose of carrying efficiency of dust collection.
Background technology
The cyclone duster structure that uses is simple at present, manufacturing, use, easy to maintenance.It is to utilize the rotation of dust-contained airflow in the whirlwind tube, makes the grit in the air-flow produce certain centrifugal inertial force, and the grit in the air-flow to peripolesis, falls to reaching the purpose of gathering dust after running into barrel under the effect of centrifugal inertial force.But because the rotary speed difference of grit of diverse location in the whirlwind tube, the distance that arrives barrel is also different, so the effect of the dust-contained airflow dedusting of diverse location is just different, existence for this reason has a significant impact the efficiency of dust collection of cyclone dust collectors.And the rotary speed of diverse location is determined by whirlwind barrel structure and corresponding flow field, dedusting theory and version with regard to present existing cyclone dust removal gas, also do not solve the more effective way of above-mentioned phenomenon, thereby influence the further development and application of cyclone dust collectors.
Summary of the invention
The utility model proposes a kind of new distinguished and admirable technology of secondary that has, on the basis of an air intake of original cyclone dust collectors, set up a new air inlet, feed new wind, to reach the purpose of the VELOCITY DISTRIBUTION in control and the change flow field from the air inlet of newly establishing.And a kind of structure that feeds the new distinguished and admirable cyclone dust collectors of secondary is provided, and can utilize the new distinguished and admirable size of secondary to change velocity distribution of flow field, make it more help collection to dust.
In cyclone dust collectors, use the principle of the new distinguished and admirable technology of secondary to be, on the basis of original cyclone dust collectors dust-cleaning principle, select suitable position to feed dust free fresh air, be that secondary is newly distinguished and admirable, utilize the fresh air that feeds, and the size of adjusting air capacity, can change the feature and the distribution thereof in flow field, make it obtain best Flow Field Distribution as far as possible, buffer action is also played in the intervention of new air simultaneously, dust-contained airflow and the position of being convenient to escape are kept apart, so that more help the collection of dust, at the new distinguished and admirable control model of secondary that can set up under the guidance of above-mentioned theory thought under the corresponding construction condition.
The utility model provides has the new distinguished and admirable cyclone dust collectors of secondary, as Fig. 1, be to settle an interlayer cover (3) in the design of the outside of discharge pipe (5), this mezzanine space has a secondary air mouth (4) in whirlwind tube outer setting, the inboard passage that forms of many through holes and whirlwind tube is arranged in the outside of interlayer cover (3), dust-contained airflow remains from an air inlet (2) and enters during work, in the whirlwind tube rotation and move down, introduce dustless new wind from secondary air mouth (4), enter interlayer cover (3), and enter in the whirlwind tube by (3), this dustless new wind can play the effect of following several respects: dust-contained airflow and discharge pipe are kept apart, can reduce the friction of dust-contained airflow and discharge pipe, reduce resistance, improve the dust-contained airflow rotary speed, can control the inlet or the speed of secondary stream simultaneously, quicken the rotary speed of dust-contained airflow; 2) because the appearance of the dustless air-flow in the interlayer cover (3) can press to cyclone wall with dust-contained airflow, not only improved the limit motion that becomes of grit, because the space of dust-contained airflow reduces, rotary speed can further improve simultaneously; 3) dust-contained airflow and air outlet are isolated, avoided the short circuit of dust-contained airflow.Can set up the flow field model and corresponding control model of the effect of this structure secondary stream.
Description of drawings
Fig. 1 is the structural representation of the new distinguished and admirable cyclone dust collectors of a kind of secondary that provide of the utility model
Number in the figure title: 1-Whirlwind barrel, air inlet of 2-, 3-interlayer cover, 4-secondary air mouth, 5-discharge pipe, 6-interlayer cover transit joint, 7-cone, 8-dust-exhausting port.
The specific embodiment
By Fig. 1 structure as can be known, the structure of this system can be welded by sheet metal and be realized.Generally be that air inlet with blower fan links to each other with the air outlet of cyclone dust collectors in dust pelletizing system, system is worked under negative pressure.The new distinguished and admirable air inlet of secondary can link with another fan outlet, also can exist with the form of opening.
Claims (4)
1. a new type cyclone dust collector is characterized in that, on the basis of an air inlet (2) that constitutes the cyclone dust collectors flow field, sets up a secondary air mouth (4), with the Flow Field Distribution in control and the change cyclone dust collectors.
2. cyclone dust collectors according to claim 1 is characterized in that: formation comprises Whirlwind barrel (1), an air inlet (2), discharge pipe (5) and cone (7), at an interlayer cover of arranged outside (3) of discharge pipe (5).
3. cyclone dust collectors according to claim 1 is characterized in that: interlayer cover (3) is extended to the outer part of Whirlwind barrel a secondary air mouth (4) is set.
4. cyclone dust collectors according to claim 1 is characterized in that: many through holes are arranged on the lateral wall of interlayer cover (3), make in the interlayer air thus path enter in the Whirlwind barrel.
