Abstract
A whirlwind dedusting device pertains to the dedusting technical field, which aims to provide a whirlwind dust catcher that can conduct dust abatement twice. An open slot, a secondary ash gathering chamber and a secondary ash discharge port are arranged on the exhaust dust of the common whirlwind dust catcher, while a spiral device is arranged on the axial line of the exhaust duct. That is to say that another one fine powder collection is carried on during the exhaust process of the common dust catcher. The utility model comprises an air inlet (1), a spiral device (2), a dust catcher tube (3), a disposable dust discharge port (4), an exhaust duct (5), a secondary ash discharge port (6), a secondary ash gathering chamber (7) and an open slot (8). The dedusting device can realize dust abatement for two times toward the dusty air current with a high dedusting efficiency.
Description
Technical field
What the present invention relates to is the high speed rotation that utilizes dusty gas, a kind of dust arrester that dust is separated from air-flow.
Background technology
The cyclone duster structure that uses is simple at present, makes, uses, safeguards simple.It is to utilize swirling eddy to make the grit in the air-flow produce certain centrifugal inertial force, and the grit in the air-flow is in the motion of the effect following peripheral of centrifugal inertial force, falls to reaching the purpose of gathering dust after running into barrel.But still there is defective in the cyclone dust collectors that use at present, mainly are poor to the capacity gauge of fine powder, how further to improve cyclone dust collectors to the capacity gauge than fine dust, are the use problems to be solved that enlarges cyclone dust collectors at present.
Summary of the invention
The invention provides a kind of cyclone dust collector with new structure.This summary of the invention is to have increased a screw at the blast pipe place on the basis of original cyclone dust collectors, allows the air-flow that enters blast pipe continue rotation, makes the remaining fine powder in the air-flow produce the limit motion that becomes under action of centrifugal force.Simultaneously on blast pipe, offer open slot, secondary dust collection chamber and secondary ash discharging hole are arranged in the place of open slot, make the fine powder on limit to enter secondary dust collection chamber from the open slot discharge.
Cyclone dust collectors are the rotations that utilize dust-contained airflow, make grit produce enough centrifugal inertial forces and reach the purpose of collecting grit.But under the condition of same swirling eddy, the centrifugal inertial force of the tiny more generation of grit is more little, and the possibility that is collected is also just more little, so cyclone dust collectors are more weak to the capacity gauge of fine powder.Still have many fine particles to fail to be collected in the air-flow of emptying, this invention is to utilize swirling eddy in the process of exhaust, utilizes the collection of the dust-cleaning principle realization of cyclone dust collectors to tiny grit again.Under the guide effect of the screw that the dust-contained airflow in the blast pipe increases newly at the blast pipe place, can form spiral in blast pipe rises, dust in the air-flow still has the limit motion in rotary course, and rise with air-flow simultaneously, when the limit dust that becomes rises to the open slot that increases newly on the blast pipe, dust is discharged from open slot, reaches the purpose of further collection dust.Owing to the dedusting effect through the front, bigger dirt material is removed on the one hand, and the dust size that enters blast pipe is little, concentration is low.On the other hand, because the diameter of blast pipe is little, same air-flow rotary speed can make grit produce big centrifugal inertial force, dust-contained airflow is in the rotation uphill process, grit has the limit effect equally, when its arrival open slot meets, enters the secondary dust storage chamber under action of centrifugal force, discharge by the secondary ash discharging hole, to reach the purpose that improves efficiency of dust collection.
Description of drawings
Fig. 1 is the structural representation of high efficiency cyclonic dust collector.Number in the figure title: 1-air inlet, 2-screw, 3-cylindrical shell, ash discharging hole of 4-, 5-blast pipe, 6-secondary ash discharging hole, 7-secondary dust collection chamber, 8-blast pipe open slot.
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.
