Summary of the invention
The object of this invention is to provide a kind of process and equipment with rape seed oil production biodiesel, if by the raw material production biodiesel except rape seed oil, methyl alcohol, NaOH or sodium methoxide, proportioning except between the each component of raw material is different from the present invention's possibility, technological process provided by the present invention and production equipment are applicable equally.
The technical solution adopted for the present invention to solve the technical problems is: by every liter of methyl alcohol (CH
3oH) dissolve approximately 24～35 grams of NaOH (NaOH) or sodium methoxide (or claim sodium methide) (NaOMe) ratio of catalyst prepare the mixture of methyl alcohol and catalyst, valve-off 23, this mixture storage is stored in to vessel 21, before each production, CH
3the two mixes OH and NaOH or NaOMe about 1 hour at approximately 40 DEG C of temperature.While starting to produce, regulate measuring pump 24: make CH
3the flow of the mixture of OH and NaOH or NaOMe and the flow of rape seed oil (unit be l/h, l/h) are than being 1: 4.5～5.5; Reactant (containing methyl alcohol and the rape seed oil of catalyst) is extracted out in vessel separately, and be heated to 50～65 DEG C of input reactors 1.Reactor 1 import and export place arranges the mechanical oscillation device that is sealed and matched with it and connects firmly, and makes the reactant in reactor 1 fully mix and strengthen course of reaction.The feature of mechanical oscillation device is: single or multiple being assemblied in same rotating shaft 10 or different rotating shaft 10 of rotor 7 that geometrical axis is crossing from rotating shaft 10, or symmetrical or asymmetric being assemblied in same rotating shaft 10 or different rotating shaft 10 between two, the eccentric throw of rotor 7 forms the phase difference of 180 °, rotor 7 becomes movable or is fixedly connected with piston 5 outer ends, in the time that rotating shaft 10 rotor drivens 7 rotate, piston 5 is driven by rotor 7, make piston 5 reciprocating, or make two adjacent pistons 5 make opposite direction, the reciprocating motion that displacement absolute value is equal, rotor 7 can move or fix in the direction of rotating shaft 10, mobile result changes the eccentric throw of rotor 7 in piston 5 present positions, change the amplitude of piston 5, piston 5 can be vibrated under different amplitudes, 1 one-tenth sealed attachment of piston waveguide tube 16 and reactor, reactant in the reciprocating motion activated reactions device 1 of piston 5, the collision probability of the interior reactant particle of reactor 1 is increased, form turbulent flow or fully mix, improve reagent flow state, make each particle flow velocity be tending towards even, avoid back-mixing, reach plug flow, generation is conducive to the motion that course of reaction is carried out, in described reactor 1, baffle plate 2 or filler can be installed, reactor 1 be shaped as tubulose or peviform, cross section is circle or non-circle, diameter evenly or change, mounting means is vertical horizontal or tilting, schedule of reinforcement is single-stage, twin-stage or multistage, and tubulose comprises straight tube, bend pipe, " L " shape pipe, "T"-shaped pipe, " ten " font pipe or coil pipe, can be single hose or multitube, the transfer pipeline that heater 25 is exported between reactor 1 entrance 18 can be taked Insulation so that reactant keeps suitable reaction temperature.Under suitable frequency and amplitude, after completion of the reaction, product (coarse biodiesel+glycerine) is introduced into separator 34 and separates, and also can adopt natural separation mode: glycerol density is large, sinks to the bottom; Coarse biodiesel density is little, floating.That separates enters water scrubber 32 containing the coarse biodiesel of methyl alcohol while adopting natural separation (or, coarse biodiesel above), washes away methyl alcohol.Through the first hydrophone 30 (drainage medium can adopt sand) after filtration of biodiesel of washing, elimination moisture, then enters water aspirator 29 (water sucting medium can adopt salt or Nacl) and further enters storage tank 36 after dehydration and obtain refined biometric diesel oil.Frequency and/or amplitude by regulation and control piston 5 can regulate and control the flow regime of reactor 1 interior reactant and the composition composition of the time of staying or product and/or conversion ratio or reaction rate; The frequency of piston 5 can change by changing buncher rotating speed, and the amplitude of piston 5 can change by changing rotor-position.Except rotor 7, piston drive mechanism also has linkage, translating cam mechanism 41, cylindrical cam mechanism 43, gear mechanism, worm-and-wheel gear or screw mechanism; Piston drive mechanism symmetry or asymmetric installation.The speed of described piston drive mechanism is adjustable or constant.Described rotor 7 comprises disc-like rotor and column rotor, and rotor 7 is fixed or movable in its rotation direction, and rotor outer surface becomes point to contact or tangent line contact with piston outer end.Described disc-like rotor 7 comprises circular section rotor or noncircular section rotor; Single or symmetrical or asymmetric being fixed in same rotating shaft 10 or different rotating shaft 10 between two of rotor 7.Described column rotor comprises cylinder, round platform or on-circular cross-section cylinder; The geometrical axis of column rotor crossing with its rotation intersect or parallel or overlap; Column rotor cross-section or out of plumb vertical with its geometrical axis; While adopting column rotor, single or symmetrical or asymmetric being fixed in same rotating shaft 10 or different rotating shaft 10 between two of column rotor.
Beneficial effect of the present invention and advantage are: the proportioning between the each component of reactant (containing methyl alcohol and the rape seed oil of catalyst) is a kind of optimum ratio, needn't improve flow velocity, and with oscillation technology raising and regulation and control flow velocity, reach turbulence effects or fully mix, improve process efficiency.Turbulent extent does not rely on net flow speed, and is regulated and controled by oscillation device, and oscillation device is adjusting amplitude and frequency infinitely.Can under very low Reynolds number (ReynoldsNumber), make fluid obtain turbulent flow or fully mix, can not only improve process efficiency, and save fluid delivery system energy consumption and equipment volume.Symmetrical tilting rotor 7 makes two-piston 5 antisymmetry motions, and left piston 5 rises, and right piston 5 declines; Right piston 5 rises, and left piston 5 declines.This technology can expand to the strengthening of any number of stages.Adjustable elastic of the present invention is large, and accommodation is wide, batch process can be converted into continuous process.The drive motors load of rotor 7 is very little, therefore its power minimum (power of motor than paddle in batch process is much smaller), because motor only need drive rotor, and the suffered moment of torsion of rotor is very little, the gravity of piston 5 does not produce moment of torsion to the rotating shaft 10 of rotor 7, because its position is crossed rotating shaft 10, motor only need overcome less moment of friction.The versatility of intensifying device is large, because reactor 1 maximizes, intensifying device is not increased, as long as motor can drive rotor 7 to rotate, rotor 7 just can promote piston 5, and size differs not too large reactor 1 can adopt onesize rotor 7.The stepper motor of adjusting amplitude is only worked within the utmost point short time of adjusting amplitude, after amplitude mixes up, shuts down, and needs hardly energy consumption.When optimum frequency and amplitude known, while not needing frequent transforming amplitudes, can as the eccentric throw of rotor 7, rotor 7 be designed and manufactured into fixing eccentric throw by this best amplitude, as shown in Figure 4,5, can remove like this stepper motor from.By the strengthening parameter of adjusting device, be frequency and the amplitude etc. of piston 5, (performance of engine is different from conversion ratio can to regulate and control the flow regime of reactor 1 interior material or the regulation and control time of staying of material or the composition of product composition, requiring for the composition of fuel may be different, thereby the present invention can regulate and control by the strengthening parameter of adjusting device the composition composition of the time of staying regulation and control biodiesel of reactant in reactor); Or can make the material in reactor 1 reach plug flow by frequency and/or the amplitude of regulation and control piston 5, this is a kind of flow regime very favourable to course of reaction.The present invention is the production efficiency that improves biodiesel or other products, reduce its cost, expand its scale, control its composition, improve key technology and the equipment of its quality etc.Structure, assemble easyly, technology realizes upper convenient and easy.The structure of amplitude adjusting mechanism is also very simple, only needs along continuous straight runs moving slide board 11.When equipment internal baffle, can strengthen turbulent extent or mixed effect, the little space between two baffle plates is equivalent to a miniature stirred tank, and whole process device is equivalent to the continuous combination of a series of micro-stirred tanks.Baffle arrangement is various informative, has annulus, square loop, hexagonal rings, triangle ring flat-plate, perforated baffle and " ten " word baffle plate etc., as shown in Figure 4, can cause Protean fluidised form.In the time that piston 5 outer ends arrange the contact 46 vertical with its center line, the reciprocating motion of piston 5 is simple harmonic oscillation.To noncircular section rotor 7, the change of distance between the stroke of piston 5, speed and two-piston 5 inner faces can determine by the concrete cross sectional shape of design rotor 7.Reactant flows into from one end of reactor serially, flows out, thereby realize continued operation from the other end.The eccentric throw of cylindrical rotor 7 does not produce eccentric load.Because rotor itself (with regard to each rotor) is a cylinder, countershaft 10 is antisymmetric, as shown in figure 14: to cylinder eccentric rotor, o point is the intersection point of its geometrical axis and its rotating shaft 10, rotor is equal in length in o point both sides, although the both sides rotor of ordering at o has eccentric throw, the eccentric load that the eccentric throw of o point both sides produces is cancelled out each other.For example, the inevitable eccentric load of being ordered by symmetrical with it b of eccentric load that a is ordered is offset.While using even number eccentric disc rotor 7 also there is eccentric load in whole device.
While adopting multistage strengthening, also clutch 37 can be disconnected, every grade with frequency separately and amplitude operation (seeing Fig. 3), because course of reaction is in the time of different stage, required strengthening frequency and/or amplitude may be different.
The Insulation of reactant intake line can be wound around flexible heating tape 47 thereon, as shown in figure 30.
