Description
Technical field
It is particularly a kind of to be able to maintain that the adjustable of cyclone separator interior air-flow stabilization the present invention relates to a kind of cyclone separator
Cyclone separator.
Background technology
Cyclone separator is a kind of equipment of the separation for gas-solid system or liquid-solid system.Operation principle is by air-flow
The rotary motion caused is introduced tangentially into, solid particle or drop with larger centrifugal inertial force is got rid of to outside wall surface and separates.It is
It is industrial to apply a kind of very wide separation equipment.For example can as automobile air cleaner or gs-oil separator.
Strong rotation is produced after impure gas enters cyclone separator at a high speed, air-flow twist enters downwards along cylinder
Enter Whirlwind barrel, referred to as contour stealth, the big drop of density or grit are thrown toward wall under the action of the centrifugal force, and in Action of Gravity Field
Under, fall to flowing out Whirlwind barrel lower port along barrel and discharge.The air-flow of rotation, to center flow, is upwardly formed in cylinder contract
Secondary vortex flow flows out through escape pipe, and the air-flow is referred to as inward eddy.
The flow velocity for normally entering the air-flow in Whirlwind barrel is fluctuation, and the abrasion of the too high not only easy barrel of flow velocity is gone back
The bounce-back of the particulate matter on barrel can to strike to be discharged from blast pipe into middle ascending air, can also cause lower port
The ascending air at place quickly forms rising, and top is relatively slow so that it can not rapid increase, so as to cause the disturbance at lower port
Aggravation, causes discharge air-flow impurity more；And if the speed of air-flow is relatively low, then it is unfavorable for ascending air rising.Other air-flow
Fluctuation can also upset contour stealth in the stabilization formed in cylinder so that be mingled with more impurity in the gas of discharge.
The content of the invention
The purpose of the present invention is in view of the above-mentioned problems existing in the prior art, it is proposed that a kind of adjustable cyclonic separator, this
Adjustable cyclonic separator can adjust as needed blast pipe rotation whether, the discharge gaseous impurity for overcoming airflow fluctuation to cause
More the problem of, prevent the upset influence of the internal contour stealth of fluctuation of air-flow.
The purpose of the present invention can be realized by following technical proposal：A kind of adjustable cyclonic separator, including cylindrical cavity with
The Whirlwind barrel of cone chamber UNICOM composition, air inlet pipe, blast pipe, Whirlwind barrel lower port.The blast pipe rotatably with rotation
Air duct body coordinates, and on the blast pipe is cased with that multiple disks can be free to move axially along blast pipe, is set vertically on blast pipe
The breach for being provided with and coordinating with projection on up-small and down-big trapezoidal projection, disk is equipped with, the breach on disk is successively from top to bottom
Increase so that when disk breach is stuck in projection, has certain spacing, and allow disk upward from locking point between disk
Motion, the disk is soft iron piece, the electromagnet for attracting disk is provided with Whirlwind barrel, the whirlwind above air inlet pipe
The space of storage disk is provided with cylinder, disk can be pulled together into the disk memory space using electromagnet
It is interior, and blast pipe is stopped operating.When electromagnet is without magnetic force, disk falls naturally under gravity, due on disk
Breach it is of different sizes so that different disks are locked on the diverse location of trapezoidal projection, should make it that the spacing between disk should not
Too big, air-flow flows through disk due to frictional force into cyclone cylinder so that disk drives blast pipe to rotate.Because blast pipe has one
Fixed inertia mass, plays a part of maintaining air-flow stabilization of speed, prevents disturbance of the airflow fluctuation to the air-flow in Whirlwind barrel
Effect, when air-flow velocity is higher, can portion of energy be converted to the kinetic energy of blast pipe rotation, when air-flow velocity is relatively low, disk is by portion
The kinetic energy of branched discharge pipe is reconverted into the kinetic energy of air-flow.The blast pipe upper end outlet is provided with centrifugal wind wheel, centrifugal wind wheel with
Blast pipe is coaxial so that centrifugal wind wheel rotates the discharge for accelerating exhaust duct to air-flow when blast pipe is rotated, so as to accelerate whirlwind
The air-flow inspiration blast pipe formed at cylinder bottom nozzle, prevents from disturbing with the mixed of outer rotational gas flow.The blast pipe and Whirlwind barrel it
Between rotatory sealing is carried out by magnetic fluid.
In above-mentioned adjustable cyclonic separator, the Whirlwind barrel lower port is provided with choked flow cone, and choked flow cone is usual
It is arranged at Whirlwind barrel lower port, in order that obtaining interior rotational airflow, preferably backflow prevents the bullet of impurity refluence.Choked flow is bored
It is connected by connecting rod with the blast pipe lower end, helical blade is provided with the conical surface of choked flow cone.So that blast pipe rotates also band
Dynamic choked flow cone is rotated, and helical blade may be such that the impurity fallen is quickly discharged, and so that getting rid of to surrounding for impurity acceleration, is prevented
The interior rotational airflow being raised is taken away and in the accumulation of lower section hopper.
In above-mentioned adjustable cyclonic separator, the blast pipe upper end puts in horizontal airway tube, the blast pipe upper end
The centrifugal lifting control mechanism of control blast pipe lifting, centrifugal lifting control mechanism bag are provided between horizontal airway tube
Include and flyball, structural principle and watt speed governing are provided with the connecting rod being connected between blast pipe upper end and horizontal airway tube, connecting rod
Device（Or it is Watt's governor）It is identical.So that when blast pipe rotating speed is high, blast pipe rises so that exhaust infratubal port distance rotation
Air duct body bottom port farther out, the impurity for preventing excessive suction inspiration excessive.
In above-mentioned adjustable cyclonic separator, the horizontal airway tube is divided into upper and lower two pipelines by dividing plate, it is described enter
Tracheae upper port is closed, and air inlet pipe upper end side wall is provided with the passage of the horizontal airway tube of UNICOM, wherein upper pipeline with it is another can
Adjust the connection of cyclone separator air inlet pipe.So that when inlet air flow is very fast, part outlet flows into another adjustable cyclonic separator
Separating treatment again is carried out, to utilize the flow velocity kinetic energy of air-flow.
In above-mentioned adjustable cyclonic separator, axial location is provided with plug in blast pipe, and plug passes through Whirlwind barrel
Connection, plug bottom is reached at Whirlwind barrel lower port.In deduster running, the center portion thereof position is in low-pressure state,
Easily cause inward turning flow short-circuit, reentrainment of dust and dust reduces purification efficiency from barrel to the bottom horizontal flow sheet at center.The heart wherein
Position sets plug, can prevent siphonage, eliminates above-mentioned disadvantage.
In above-mentioned adjustable cyclonic separator, four projections are circumferentially symmetrically arranged with along blast pipe.
Compared with prior art, this adjustable cyclonic separator has advantages below：
The present invention reduces influence of the inlet air flow fluctuation to cyclone separator interior air-flow, less impurity using rotatable blast pipe
With the discharge rate of air-flow, improve separating effect, using electromagnet can control blast pipe rotation whether, so as to adapt it to reality
The need of work on border.
