Abstract
The present invention invents a kind of double ash bucket inertial dust separators, and inlet improves the inlet velocity of dusty gas using jet pipe acceleration, and speed is made to reach a suitable numerical value, and vertical deduster of injecting collides first obstruction after gas is accelerated --- sloping baffle.Slow down for the first time by collision friction, larger granule particles are inclined by the baffle direction of motion, and then are decelerated into ash bucket 1, and smaller dust granule further slows down with rocket motor, since centrifugal force enters ash bucket 2.Multiple abrupt changes of cross-section and sloping baffle is arranged in deduster, primarily to increasing friction, reduces fluid flow rate on the whole.The more existing inertial dust separator of deduster overall volume is substantially reduced, can more flexible some narrow spaces of adaptation.Such as large space use can multiple dedusters in parallel.2 left side of ash bucket is provided with pressure compensation opening, and it acts as the atmospheric pressure of balance ash bucket 2 and external environment, improve the fluid state in ash bucket 2, are preferably removed convenient for dust.The inertial dust separator can not only reduce reentrainment of dust, also reduce the resistance in gas flow, also improve efficiency of dust collection to a certain extent.And the reduction of entrance wind pressure directly reduces the power of wind turbine, achievees the effect that energy saving.
Description
Technical field
The present invention relates to green technology apparatus field, specially a kind of double ash bucket inertial dust separators.
Background technology
Currently, well known inertial dust separator has two kinds of collision type deduster and reverse-flow type deduster, former deduster master
If by the advance of one or several baffle air-flows, the grit in air-flow is made to separate, although the form deduster gas
Body flow resistance is small, but its efficiency of dust collection is low.The characteristics of latter deduster is that inlet air flow is divided into shallow bid gas with baffle
To make one arbitrary air-flow have similarly compared with small swing radius and larger angle of revolution various baffle arrangements may be used, most in stream
It is typically blinds baffle plate, although blinds baffle plate can improve the speed before air-flow abrupt turn, separation can be effectively improved
Efficiency, but the excessively high secondary fly-up that can cause arrested particles of speed.So in order to overcome the secondary dirt of existing deduster,
Gas flow resistance is big, the relatively low deficiency of efficiency of dust collection.Therefore, the present invention provides a kind of inertial dust separator, to original device
It improves and optimizates, which can not only reduce reentrainment of dust, the resistance in gas flow be also reduced, also certain
Efficiency of dust collection is improved in degree.And the reduction of entrance wind pressure directly reduces the power of wind turbine, reaches energy saving effect
Fruit.
Invention content
The present invention is a kind of double ash bucket inertial dust separators, and the problem to be solved in the present invention is to reduce easily to occur in dust removal process
Reentrainment of dust phenomenon, reduce the resistance in gas flow, improve efficiency of dust collection to a certain extent.
The technical solution adopted in the present invention：
A kind of double ash bucket inertial dust separators, including dusty gas entrance, purified gas outlet, ash bucket, turning, baffle, pressure are provided
Dynamic balance hole etc..
With the above structure, by the multiple abrupt changes of cross-section and sloping baffle are set make dusty gas pass through inertia force and
The effect of centrifugal force makes dust fall into two ash buckets, and gas is discharged by purified gas outlet after purification.
The inlet velocity of dusty gas is improved using jet pipe acceleration in inlet, and speed is made to reach a suitable number
Value, vertical deduster of injecting collides first obstruction after gas is accelerated --- sloping baffle.Pass through collision friction for the first time
Slow down, larger granule particles are inclined by the baffle direction of motion, and then are decelerated into ash bucket 1, smaller dust granule
Further slow down with rocket motor, since centrifugal force enters ash bucket 2.Multiple abrupt changes of cross-section and sloping baffle is arranged in deduster, main
If in order to increase friction, reduce fluid flow rate on the whole.The more existing inertial dust separator of deduster overall volume is substantially reduced,
It can more flexible some narrow spaces of adaptation.Such as large space use can multiple dedusters in parallel.As deduster is faced
Figure cuts open shown in figure, and 2 left side of ash bucket is provided with pressure compensation opening, and it acts as the atmospheric pressure of balance ash bucket 2 and external environment, improve
Fluid state in ash bucket 2, preferably removes convenient for dust, to prevent dust retaining pressure balance hole, therefore its position is arranged
Ash bucket 2 by the upper position, to prevent dust from being run out of from pressure compensation opening, one layer of fine and closely woven filter device is set outside hole.
Description of the drawings
Fig. 1 is the front view sectional view of double ash bucket inertial dust separators of the invention.
1 is dusty gas entrance in Fig. 1, and 2 be turning, and 3 be baffle 2,4 be ash bucket 1,5 be baffle 3,6 be that baffle 4,7 is
Pressure compensation opening, 8 be ash bucket 2,9 be baffle 5,10 be purified gas outlet, and 11 be baffle 1.
Specific implementation measure
Dusty gas makes flow velocity reach a suitable numerical value in inlet by jet pipe acceleration, and the gas injection after acceleration is inclined
Slanting baffle 1 passes through collision friction and slows down for the first time, and larger granule particles are inclined by the baffle direction of motion, and then are decelerated
Ash bucket 1 is fallen into the direction of ash bucket 1, then by the effect of the friction eceleration of 2 baffle 3 of baffle, smaller dust granule is with gas
Circulate curved further deceleration, since centrifugal force enters 2 direction of ash bucket, then is fallen by the effect of the friction eceleration of 4 baffle 5 of baffle
Ash bucket 2.And cleaned gas is then discharged from purified gas outlet after dedusting.The more existing inertial dust collection of deduster overall volume
Device is substantially reduced, can more flexible some narrow spaces of adaptation.Such as large space use can multiple dedusters in parallel.Such as
Deduster front view cuts open shown in figure, and the left side of ash bucket 2 is provided with pressure compensation opening, and it acts as balance ash bucket 2 and external environments
Atmospheric pressure improves the fluid state in ash bucket 2, is preferably removed convenient for dust, to prevent dust retaining pressure balance hole, therefore handle
The setting of its position ash bucket 2 by the upper position, to prevent dust from being run out of from pressure compensation opening, to be arranged outside hole one layer it is fine and closely woven
Filter device.
