The specific embodiment

The present invention need not improve the flow velocity of process fluid, does not promptly need to increase the energy consumption of fluid delivery system and equipment volume and improves process efficiency.The present invention improves by the technological thought that applies an oscillation device (can be mechanical oscillation or other, as electromagnetic viscosimeter) and the flow velocity of adjusting, control procedure.Utilize the present invention can make process must guarantee minimum Reynolds number needn't resembling traditionally, the turbulent extent of fluid does not depend on that net flow speed (has a lot of negative effects because improve flow velocity, as increase power consumption, increase equipment volume and investment, factory building space or the like), and controlled and regulate by oscillation device.

During net flow, promptly the Reynolds number during friction is

${\mathrm{Re}}_n=\frac{\mathrm{dup}}{\mathrm{\μ}}$

The Reynolds number of vibration also can be expressed as

${\mathrm{Re}}_o=\frac{\mathrm{dup}}{\mathrm{\μ}}$

Wherein flow velocity u division is as follows:

1, sinusoidal motion

Piston 5 move distances are

z＝asinωt

Movement velocity is

U=ω α cos ω t or u=2 π f α cos ω t

Maximum movement speed is

U=ω α or u=2 π f α

So the Reynolds number of vibration is

${\mathrm{Re}}_o=\frac{\mathrm{\ωad\ρ}}{\mathrm{\μ}}$ Or ${\mathrm{Re}}_o=\frac{2\mathrm{\πfad\ρ}}{\mathrm{\μ}}$

2, cosinusoidal motion

Piston 5 move distances are

z＝αcosωt

Movement velocity is

U=-ω α sin ω t or u=-2 π f α sin ω t

Maximum movement speed is

U=|-ω α |=ω α or u=|-2 π f α |=2 π f α

So the Reynolds number of vibration is

${\mathrm{Re}}_o=\frac{\mathrm{\ωad\ρ}}{\mathrm{\μ}}$ Or ${\mathrm{Re}}_o=\frac{2\mathrm{\πfad\ρ}}{\mathrm{\μ}}$

3, disk cam

Disk cam is a kind of on-circular cross-section rotor, and when adopting the disk cam structure, the macroscopic motion speed of fluid depends on the concrete contour curve of cam, and the contour curve of cam can require design according to technical process, finds the solution u according to concrete contour curve then.Here provide several forms of motion commonly used.

1) movement at the uniform velocity

Rise: $u=\frac{a}{{\mathrm{\δ}}_0}\mathrm{\ω}$ Backhaul: $u=-\frac{a}{{\mathrm{\δ}}_0}$

Acceleration-deceleration motion such as 2)

Rise acceleration such as () being made as:

$u=\frac{4a}{{\mathrm{\δ}}_0^2}\mathrm{\ω}$

Backhaul decelerations such as () being made as:

$u=\frac{4a({\mathrm{\δ}}_0-\mathrm{\δ})}{{\mathrm{\δ}}_0^2}\mathrm{\ω}$

3) sinusoidal accelerated motion

$u=\frac{a}{{\mathrm{\δ}}_0}[1-\cos \left(\frac{2}{{\mathrm{\δ}}_0}\mathrm{\δ}\right)]\mathrm{\ω}$

4) cosine accelerated motion

$u=\frac{\mathrm{\πa}}{2{\mathrm{\δ}}_0}\sin \left(\frac{\mathrm{\π}}{{\mathrm{\δ}}_0}\mathrm{\δ}\right)\mathrm{\ω}$

4, linkage (consulting Fig. 5)

The macroscopic motion speed of fluid can be found the solution as follows:

The speed of crank 34 end points s is u _s=ω l ₁

θ＝90°-(β+γ)

si＝u _scosθ＝ωl ₁sin(β+γ)

u _p＝si/cosγ＝ωl ₁(sinβ+cosβtanγ)

sj＝l ₁sinβ

So sin γ=sj/l ₂=(l ₁/ l ₂) sin β=λ sin β

$\tan \mathrm{\&gamma;}=$ $\frac{\sin \mathrm{\&gamma;}}{\cos \mathrm{\&gamma;}}=\frac{\mathrm{\&lambda;}\sin \mathrm{\&beta;}}{\sqrt{1-{\mathrm{\&lambda;}}^2{\mathrm{<figure-callout\; id="2"\; label="sin"\; filenames="A20051003128500151.png,A20051003128500181.png"\; state="\{\{state\}\}">sin</figure-callout>}}^2\mathrm{\&beta;}}}$

So $u=u_p={\mathrm{\&omega;l}}_1(\sin \mathrm{\&beta;}+\frac{\mathrm{\&lambda;}\sin \mathrm{\&beta;}\cos \mathrm{\&beta;}}{\sqrt{1-{\mathrm{\&lambda;}}^2{\mathrm{<figure-callout\; id="2"\; label="sin"\; filenames="A20051003128500151.png,A20051003128500181.png"\; state="\{\{state\}\}">sin</figure-callout>}}^2\mathrm{\&beta;}}})$ Or $\frac{u}{\mathrm{\&omega;}{\mathrm{<figure-callout\; id="1"\; label="l"\; filenames="A20051003128500151.png,A20051003128500161.png"\; state="\{\{state\}\}">l</figure-callout>}}_1}=\sin \mathrm{\&beta;}+\frac{\mathrm{\&lambda;}\sin \mathrm{\&beta;}\cos \mathrm{\&beta;}}{\sqrt{1-{\mathrm{\&lambda;}}^2\mathrm{<figure-callout\; id="2"\; label="si\; n"\; filenames="A20051003128500151.png,A20051003128500181.png"\; state="\{\{state\}\}">si</figure-callout>}{n}^{}{}^2\mathrm{\&beta;}}}=m$

M represents the ratio of fluid macroscopic motion speed (piston 5 speed) and crank 34 end points linear velocities, and this formula is with angular velocity omega, the length l of fluid macroscopic motion speed u and crank 34 ₁, certain instantaneous position β and crank 34 and connecting rod 33 length than λ=l ₁/ l ₂Associate, the length of the angular speed, length, crank 34 that can need design crank 34 by technical process and connecting rod 33 parameter such as compares to obtain the optimal movement effect in view of the above.

5, translating cam 35

The characteristics of motion of curved surface translating cam 35 is wanted the concrete shape of known curved surface, and curve form can be determined according to process condition, only gives the computational methods of out-of-plane translating cam 35 (consulting Fig. 6 to 12) here.

If the translational speed of plane translating cam 35 is v, the level inclination on inclined-plane is ε, and then obviously the speed (being fluid macroscopic motion speed) of piston 5 is

U=vtan ε or this formula association of u/v=tan ε fluid macroscopic motion speed u and the movement speed v of translating cam 35 and the level inclination ε on inclined-plane, can design these parameters to obtain the optimal movement effect by the technical process condition in view of the above.

Rotor 8 design theories and method:

Rotor 8 is the elements that produce vibration, below is design theory and the method that example provides rotor 8 with cylindrical rotor 8.The installation form of rotor 8 has multiple.

1, geometrical axis and rotation meet at the longitudinal section geometric center, consult Figure 17.

As rotor 8 self geometrical axis O ₃O ₄With its rotation O ₁O ₂When intersecting at rotor 8 longitudinal cross-section geometric center O (being rotor 8 centers of gravity), the eccentric throw at two ends, rotor 8 left and right sides equates that piston 5 does not have off-centre when being in O point top, thereby does not have amplitude, and promptly piston 5 can not produce reciprocating motion.

If the eccentric throw of eccentric rotor 8 ends (is example with the right part) is e, i.e. O ₁O ₃=e, O ₁O ₂With O ₃O ₄Angle be α, draw AO ₃Perpendicular to O ₁O ₂, AO then ₁=esin α, AO ₃=ecos α.When piston 5 was in position B, the amplitude a of piston 5 was peak (piston 5 contacts with the F point) that piston 5 can arrive and its minimum point that can arrive (piston 5 contacts with the B point) difference in height half, promptly

a＝(FC-BC)/2＝[(CD+DF)-(BD-CD)]/2＝CD

As seen amplitude promptly is the distance of two axial lines in vertical, or in a broad sense, is the two axial lines of the axis of piston 5 and rotor 8 distance between gained 2 C, D when intersecting.

Make CO ₁=x, this x is from O ₁Point (being the intersection point of rotation and rotor 8 end faces) begins to calculate, and can this x during as regulating piston 5 amplitudes rotor 8 the distance that should move.OO ₁=e/sin α, CO=OO ₁-CO ₁=e/sin α-x, AC=CO ₁-AO ₁=x-esin α, AO=OO ₁-AO ₁=e/sin α-esin α, when piston 5 was in diverse location x, the distance C D between the two axial lines changed with x.Find the solution this variation relation below.

By Δ OCD～Δ OAO ₃ $\frac{\mathrm{CD}}{{\mathrm{AO}}_3}=\frac{\mathrm{CO}}{\mathrm{AO}},$ $\mathrm{CD}=\frac{\mathrm{<figure-callout\; id="3"\; label="CO\; AO\; AO"\; filenames="A20051003128500151.png"\; state="\{\{state\}\}">CO</figure-callout>}}{\mathrm{AO}}{\mathrm{AO}}_{}{}_3$ To get after the above relational expression substitution

Amplitude $a=\mathrm{CD}=\frac{e-x\sin \mathrm{\&alpha;}}{\cos \mathrm{\&alpha;}}$ $=\frac{e}{\cos \mathrm{\&alpha;}}$ $-x\tan \mathrm{\&alpha;}$

Rotor 8 geometrical axis and rotation do not meet at the longitudinal section geometric center but amplitude when not belonging to following 2,3 two kind of situation is still calculated by following formula.

The relation of a and x is design or the basis of selecting fluid pressure drive device.

2, rotor 8 geometrical axis and rotation meet at the rotor 8 end face centers of circle (is example with the right side), consult Figure 18.

This moment rotor 8 right side eccentric distance e=0, in fact obvious amplitude a=CD=xtan α, can get a=-xtan α in situation 1 eccentric distance e=0 of ordering, negative sign is represented rotation under geometrical axis, or expression piston 5 is in the left side of two axial lines intersection point O.

3, geometrical axis and rotation intersect at end face (is example with the right side) edge, (consulting Figure 19).

In fact this situation is exactly the 1st situation, so

Amplitude $a=\mathrm{CD}=\frac{e-x\sin \mathrm{\&alpha;}}{\cos \mathrm{\&alpha;}}$ $=\frac{e}{\cos \mathrm{\&alpha;}}$ $-x\tan \mathrm{\&alpha;}$

Or it is as follows to derive:

Make O ₃A is perpendicular to OO ₁And prolong friendship sideline, rotor 8 cross section in the K point,

Amplitude a=CD=BD-BC=O ₃K-BC=e/cos α-xtan α.

With rotor 8 left parts is that example can get same conclusion.

To round platform and on-circular cross-section (needing known curve shape) rotor 8 etc., computational methods are similar to the above.

The present invention makes the fluid in the process device 1 produce vibration by oscillation device is set, rather than as traditional process device, improve Reynolds number to increase turbulence level or mixed effect by improving flow rate of fluid, after oscillation device is set, the Reynolds number of fluid does not depend on net flow speed, but improve, regulate and control by oscillation device (can be mechanical oscillation or electromagnetic viscosimeter).Thereby do not increase the energy consumption of fluid delivery system and the volume of equipment, and can improve process efficiency, again can energy savings, fund, material and factory building space etc.The generation of vibration is (as rotor 8 (consulting Fig. 1) by piston 5 and piston drive mechanism, linkage (consulting Fig. 4), translating cam mechanism 35 (consulting Fig. 6 to 12), cylindrical cam mechanism 37 (consulting Figure 13)) realizes, and, piston drive mechanism is versatile and flexible, the vibration velocity of piston 5, amplitude, the physical dimension of factors such as frequency and piston drive mechanism, cross sectional shape (contour curve), speed, parameter correlation such as locus and direction connection, therefore can obtain the required fluid optimum vibration frequency of technical process by regulating these parameters, amplitude, hunting speed and Reynolds number etc., operating flexibility is big, and condition of compatibility is wide.With rotor 8 (consulting Fig. 1) is example, and rotor 8 also can move along axis direction for column.The rotating speed of rotor 8 promptly is a rotating speed of motor, and the frequency of oscillation that change with control piston 5 only need change and control rotating speed of motor; The cross sectional shape (contour curve) that changes rotor 8 just can obtain the rule of vibrating accordingly; Just can change the amplitude of piston 5 along rotating shaft direction movable rotor 8.The inclination angle of the length of the rotating speed of crank 34 and length and connecting rod 33 or change translating cam mechanism 35 and speed and curve form also can obtain best piston 5 characteristics of motion in the change linkage, thereby obtain best Reynolds number.The shape variation of baffle plate 2 can be selected baffle plate 2 according to process conditions, and this brings great convenience to technical process.Utilize the present invention the intermittently operated process of mechanical agitation one class can be converted into the continued operation process; Make very long process of holdup time be able to grow-footpath is than realization, reduction equipment volume greatly in the continuous tubular type process device 1 little, that size is less.The present invention can be used for various procedures, as diabatic process, mass transport process, Momentum Transfer process and chemical reaction process (heat exchanger, rectifying column, reactor) etc., also a plurality of oscillation devices can be installed on process device 1, oscillation device symmetry is in twos installed or asymmetric installation.
