As shown in Fig. 2, for the first the heat exchanger structure schematic diagram of the embodiment of the present invention based on centrifugation design method;
Fluid A is entered by the first flow channel 1 in the first mixing chamber 5, and fluid B enters the by the second flow channel 2 In one mixing chamber 5, fluid A and fluid B are subjected to mixed heat transfer, obtain fluid-mixing.The temperature of the fluid A and fluid B is not Together, density is different and immiscible;If the temperature of fluid A is T1(unit K), density ρ1(unit kg/m3), flow m1 (unit kg/s), specific heat capacity c1(unit is J/ (kgK), correspondingly, temperature, density, flow and the specific heat capacity of fluid B Respectively T2、ρ2、m2And c2.After fluid A and fluid B carries out being sufficiently mixed heat exchange in the first mixing chamber 5, ideally, recognize It is adiabatic for entire first mixing chamber 5, known by the conservation of energy:
m1c1T1+m2c2T2=(m1c1+m2c2)T0
Therefore after being sufficiently mixed heat exchange, the temperature of fluid-mixing is:
T0=(m1c1T1+m2c2T2)/(m1c1+m2c2)
By mass-conservation equation after mixing it is found that the flow of fluid-mixing is:
m0=m1+m2
Derived by the above basic principle it is found that this heat exchanger heat exchange it is extremely strong, can reach most in short time, small space Good heat transfer effect.And in the target temperature T of given fluid-mixing0When, there are best inlet flow rate ratios:Its key parameter is fluid flow, fluid A flows m1Ranging from 0.1~2kg/s, fluid B fluid flows m2 Range is determined according to best inlet flow rate relationship:Fluid A temperature T1Ranging from 350~450K;Mixing The temperature T of fluid0Ranging from 310~400K;Heat exchanger volume range is from 0.1~0.4m3
Fluid-mixing enters the first centrifugal chamber 6 will be mixed after mixed heat transfer using centrifugal separation method by centrifugal device A7 Collaborate body to separate, obtains target fluid A and target fluid B;Centrifugal device A7 is as shown in Figure 2, the drive shaft of centrifugal device A7 External power plant is connected, centrifugation force effect Fluid field motion analysis calculates as follows:
It is illustrated in figure 3 and centrifuges force analysis schematic diagram, a certain liquid pearl is analyzed, two solid black point tables in figure Show same liquid pearl, for the force analysis under different stressing conditions, the centrifugal force suffered by liquid pearl is:
Fc=m ω2r
Wherein, FcFor the centrifugal force (unit N) suffered by liquid pearl, m is the quality (unit Kg) of liquid pearl, and ω is that centrifugation fills The angular velocity of rotation (unit rad/s) of A7 is set, r is the distance between liquid pearl and the drive shaft of centrifugal device A7 radius (unit For m).
The downward component of the centrifugal force is:
F′c=Fc·sinα
Suffered normal pressure N (unit N) is the liquid pearl under the action of the centrifugal force:
N=Fc·cosα
Wherein α refers to the angle between the centrifuge blade and drive shaft of centrifugal device A7, generally takes 30 °~50 °, it is described from Lobus cardiacus piece level is on the lower side.
Buoyancy F suffered by the liquid pearlf(unit N) is:
Ff=ρ gV
Wherein, ρ is density (the unit Kg/m of liquid pearl3), V is volume (the unit m of liquid pearl3), g is acceleration of gravity.
The upward component of the buoyancy is
F′f=Ff·cosα
Liquid pearl normal pressure N ' (unit N) suffered under buoyancy is
N '=Ff·sinα
The then frictional force suffered by liquid pearl:
Fm=f (N+N ')
Wherein, f refers to the frictional force between liquid pearl and the centrifuge blade.
By the relationship between power and movement it is found that the movement of final liquid pearl is by the downward component F ' of centrifugal forcecAnd friction Power FmThe separation F ' upward with buoyancyfThe sum of determine.For heavy-fluid pearl, centrifugal force component is more than the sum of frictional force and buoyancy component, That is F 'c> Fm+F′f, liquid pearl moves to the first big centrifugal chamber position of radius;For light liquid pearl, centrifugal force component is less than frictional force The sum of with buoyancy component, i.e. F 'c< Fm+F′f, liquid pearl floats to be moved to the first small centrifugal chamber position of radius.It can be seen that density Different weight liquid will be layered reverse flow in the first centrifugal chamber, be based on this, two kinds of fluids will positioned at the first centrifugal chamber not It is flowed out at the flow pass of radius, it is assumed that target fluid A density is more than target fluid B, and the big target fluid A of density is from radius Big the second flow pass 4 outflow, the small target fluid B of density is from small the first flow pass 3 outflow of radius, finally by its point It leaves.
Fluid A, B are passed through in the first mixing chamber 5, wherein assuming that fluid A is main heat exchanging fluid.Be passed through fluid A with The mode that atomization sprays into may be used when fluid B, increase contact surface and it is forced to be uniformly mixed, or add in 5 body of the first mixing chamber Enter a blender or temperature-uniforming plate to realize quickly blending and heat exchange, to keep the temperature of fluid-mixing almost the same.
Target fluid A and target fluid B is flowed out by the second flow pass 4 and the first flow pass 3 respectively, to avoid mesh Mark fluid A and target fluid B is wasted, and design of heat exchanger method of the invention, which can be arranged, makes target fluid A or target fluid B follow The device that ring utilizes.Such as after previous step centrifuges, more pure and that density the is big fluid of the small fluid of usual density can contain The fluid for having a small amount of density small, therefore can the small fluid discharge of density be subjected to subsequent work flow or collection, and when needs avoid When the small fluid wastage of density, the big fluid of density should then be recycled, therefore density can be kept small with design cycle device Fluid circulation utilize.It should be noted that the big fluid flow of density cannot directly be counted according to the big fluid of import density at this time It calculates, and needs to consider the accounting of the small fluid of density wherein.Therefore the big fluid flow needs of density are rationally controlled.
