Description
Technical field
The present invention relates to a kind of bipyramid cylinder cyclone dust collectors, relate generally to cyclone dust removal air cleaning unit, Ke Yiying
For detaching the small dust in gas.
Background technology
From 1886 Morse (Morse) cyclone dust collectors apply for a patent and come into operation since, be widely used to
In industry, the course of work of cyclone dust collectors is：Dust-contained airflow is from air inlet with higher tangential velocity (generally 12~25m/
S) after entering cyclone dust collectors cylindrical portions, air-flow becomes circular motion from linear motion, the loop space between inside and outside cylinder
Top-down spiral motion is done with cone position, forms contour stealth；The air-flow centrifugal force that grit generates in rotary course
Grit is set to get rid of to wall；Grit contacts with wall and loses inertia force, falls along wall surface, is detached with gas under the effect of gravity,
Most enter in ash-collecting tube through cone base afterwards；When a certain position of air-flow arrival cone, one is formed by the spiral on lower turn
Line moves, i.e. inward eddy；The gas of final purification is discharged through exhaust pipe, thus the grit of a part of collection at large is also escaped.For
The efficiency of dust collection of cyclone dust collectors is improved, existing technical measures have：It forces to form spiral wind using entrance spirally-guided, in circle
The internal face or outside wall surface of canister portion point cast spiral stream guidance slot processed, or obtain continuous spiral bar by welding or other fixations
Item or flow guide bar reach increase frictional resistance, reduce windage, while increasing dust and gas centrifugal force, reduce crossfire or inhibit secondary counter
Ash improves dust removing effects；Install the removal of the central shaft with flight accumulate on the grit, horizontal central shaft of barrel band spiral and
Increase the mode of moisture film to remove the grit that air neutralization rests on barrel；The double-deck cyclone dust removal is to increase to sieve in cylindrical portions
Net changes interlayer wind field and improves efficiency of dust collection, etc..These technical measures are led on the basis of existing cyclone dust removal principle
It crosses and improves tube structure to improve the efficiency of cyclone dust removal.Analysis and practice have shown that, due to cyclone dust collectors operation principle limit
System, can be effectively treated PM5.0 or more grits, but be difficult to remove or collect PM5.0 dust below.Increase rear class filter plant or
The effect for the grit for removing PM2.5 can be improved using the measures such as helicla flute, moisture film or spray are increased on rotatable conic tube
Rate, but rear class filtering safeguards inconvenient, active screw cone " connecing " dirt mode when without using liquid film, efficiency of dust collection will under
Drop, meanwhile, screw cone manufacture difficulty is big, and seal request is high between other components.
Invention content
In order to overcome above-mentioned disadvantage of the existing technology, the present invention to provide a kind of bipyramid cylinder cyclone dust collector, pass through
Elongated straight slot on conical shell makes grit enter interlayer, the activity cone cylinder of rotation increase grit enter interlayer probability and
The grit for having blocked the rebound of fixed cone barrel, avoids grit from being again introduced into whirlwind field, has changed simultaneously dust-contained airflow and tapered wall
Relative wind velocity makes grit lose speed quickly.Hydrojet can clean cone cylinder wall and accelerate the decrease speed of grit in interlayer, also not
Influence original whirlwind field.The present invention solves the deficiencies in the prior art, can effectively remove and be more than PM1.5 microns in dust and gas
Grit, the PM2.5 grits being especially detrimental to health improve the separative efficiency of dust and gas, dust and gas concentration adapt to it is wide, can
To use low wind speed dedusting, noise to be greatly reduced.
A kind of bipyramid cylinder cyclone dust collector of the present invention, including：Cyclone dust collectors (1), floating bearing (2), activity cone
Cylinder (3), fixed cone cylinder (4), air duct case (5), dust collecting trough (6)；The cyclone dust collectors (1) are fixed in air duct case (5), revolution
The outer ring of bearing (2) is fixed on the outer barrel of cyclone dust collectors (1), and activity cone cylinder (3) is fixed on the inner ring of floating bearing (2)
On, fixed cone cylinder (4) seals affixed, dust collecting trough (6) by the outer ring of floating bearing (2) and the outer barrel of cyclone dust collectors (1)
It is fixed under the ash bucket of cyclone dust collectors (1)；
Coaxially with fixed cone cylinder (4), activity cone cylinder rotating speed is 10~120 revs/min to the activity cone cylinder (3)；The activity
There are a plurality of elongated and discontinuous spiral straight slot, the straight slot gross area to be not more than the 5% of activity cone cylinder (3) surface area in cone cylinder (3),
The wide b of single straight slot is less than 3mm；There is sealing device in the dust collecting trough (6), prevents air from the ash bucket end of cyclone dust collectors (1)
Effusion；
If a diameter of D of outer barrel of cyclone dust collectors (1), then the big area of bed of activity cone cylinder (3) is equal to D, small area of bed
DdIt is 1.8~2.4D for 0.3~0.4D, cone cylinder length H, interlayer H is formed by between activity cone cylinder (3) and fixed cone cylinder (4)1
More than 3mm；Between the activity cone cylinder (3) and the interlayer of fixed cone cylinder (4), nozzle is installed to clean activity cone cylinder (3), fix
The liquid film of the wall surface of cone cylinder (4), moistening is also beneficial to absorption grit and accelerates grit decrease speed.
Preferably, air duct case (5) matches into air duct with the air intake vent of cyclone dust collectors (1), and in air duct, installation is more in case (5)
Processing air quantity will be increased by covering cyclone dust collector.
As it can be seen that a kind of bipyramid cylinder cyclone dust collector of the present invention, it is higher into wind speed to change cyclone dust collectors needs
It spends to increase the centrifugal force of grit, the operation principle for the decline that runs out of steam by grit.When dust and gas is screwed into activity cone cylinder, centrifugal force
Grit is set to be passed through from the elongated straight slot of activity cone cylinder, the interlayer formed into two cone cylinders declines and imports along fixed cone cylinder inner wall
Ash bucket；After grit enters interlayer, the activity cone cylinder of rotation has blocked the grit to rebound from fixed cone cylinder inner wall, avoids grit by again
Secondary to be blown into whirlwind field, smoothly flow field is also beneficial to the smooth decline of grit in interlayer.There is the present invention device simply, easily to make
It makes, is easy to maintain, the advantages such as operating noise is low, needing clean gas suitable for family, market, office and industrial production etc.
Or the occasion of dust and gas separation.
The present invention compared with prior art, has following obvious prominent substantive distinguishing features and marked improvement：From
Mental and physical efforts make grit be passed through from the elongated straight slot of activity cone cylinder, and the activity cone cylinder of rotation increases probability and gear that grit enters interlayer
Grit is closed in interlayer, avoids being again introduced into whirlwind field, high dust collection efficiency, concentration by the grit for having lived the rebound of fixed cone barrel
It adapts to wide, manufactures, safeguards simple and convenient, be easy sealing, realize low wind speed dedusting, when cyclone dust collectors work is greatly reduced
Noise.
