AvRepresent.Generally speaking, when described flow difference or time difference are controlled in 1%, can think each passage flow resistance about equally.
As previously mentioned, can make the shape and size of described a plurality of distribution passages roughly the same, thereby make described a plurality of distribution passage have roughly the same flow resistance.
In many cases, a plurality of distribution passages in the above-mentioned fluid distributing apparatus are micro-sized channel, have very high flow resistance.Such as, when described fluid distributor is used in the parallel reactions system when reactant or other dispensed materials are in a plurality of parallel reactors, a plurality of tributary port of this fluid distributor can be connected on the front end or the rear end of each parallel reactor respectively, the distribution passage of common mouthful of each connection and a tributary port is positioned on the fluid path like this.If described a plurality of distribution passage is the micro-sized channel with identical flow resistance, its flow resistance is much larger than the flow resistance of other parts of the fluid path at its place, thereby the flow resistance of other parts can be ignored, many the fluid paths at then a plurality of distribution passages place have roughly the same flow resistance, flow on feasible affiliated many fluid paths about equally, thereby material can be evenly distributed on each fluid path, also promptly be evenly distributed in each reactor.
Described micro passage or micro-sized channel are for the passage of macro-scale.Usually, be called macro-scale greater than the yardstick of 1mm, if the smallest dimension of passage is more than or equal to macro-scale, this passage is the passage of macro-scale, and relatively, the micro passage is meant the passage of smallest dimension less than macro-scale.Usually, the smallest dimension of passage is meant the smallest dimension of its minimum cross-section, and wherein, cross section is a rectangle, and its smallest dimension is the minor face of this rectangle; Cross section is circular, and its smallest dimension is this diameter of a circle; Cross section is leg-of-mutton, and its smallest dimension is this shortest leg-of-mutton height; For erose cross section, its smallest dimension can be determined by the following method: make the circle of a maximum in this cross section, this diameter of a circle i.e. the smallest dimension of this cross section.
Described micro passage can be the passage of smallest dimension less than 1mm, preferably, can be smallest dimension less than 0.5mm, or more preferably, less than 0.2mm, or less than the passage of 0.1mm.Described micro passage also can be the littler passage of smallest dimension, such as, less than 70 μ m, less than 50 μ m, less than 40 μ m, less than 30 μ m, less than 20 μ m, less than 10 μ m, less than 7 μ m, less than 5 μ m, less than 3 μ m, less than 2 μ m, less than 1 μ m, less than 0.7 μ m, less than 0.5 μ m, less than 0.3 μ m, or less than 0.1 μ m, this depends primarily on the needs of practical application.Therefore, the scope of the smallest dimension of micro passage can be between 0.1 μ m～1mm, preferably, and can be between 0.5 μ m～0.5mm, perhaps more preferably, can be between 1 μ m～100 μ m.
Wherein, the micro passage can be to be formed at the interior micropore of object, slit etc., also can make microflute at body surface by micro fabrication, with Sealing microflute is sealed the back again and forms the micro passage.The making method of micro passage includes but not limited to mechanical scratching, mechanical grinding and polishing, chemical corrosion, electrochemical corrosion (for example stainless steel commonly used electropolishing), ion bombardment, laser beam machining, casting, dry etching and sandblast etc.The material that is suitable for making the micro passage includes but not limited to metal and alloy (such as copper, stainless steel etc.), silicon, glass, plastics etc.
In the above-mentioned fluid distributing apparatus, the size of single distribution passage can be identical from the beginning to the end, also can be vicissitudinous.Such as, because the current limliting step-down is mainly played in the micro passage, therefore medium is higher at input end pressure, output end pressure is lower, therefore guaranteeing under the enough big prerequisite of flow resistance, the passage (being beloid passage) that can adopt size to increase gradually can effectively reduce the output terminal flow rate of fluid.
In the above-mentioned fluid distributing apparatus, described outer circumferential face or inner peripheral surface are meant a basic closed surface, and just cross section is the surface of the line of closed line or basic closure, and it can be the surface of circumferential surface, conical surface, prismatic surface and so on.Corresponding, except being cylindrical body or the cone, described core also can be the object that an outer circumferential face can be provided of other Any shape, such as frustum, pyramid, prism curved surface etc.Similarly, described housing also can be Any shape can provide one can with the object of the close-fitting inner peripheral surface of outer circumferential face of core.
In the above-mentioned fluid distributing apparatus, it is very big that the input port size can be done, available screw thread, and means such as welding connect external pipe and seal, so very high pressure can be born in the joint.
In the fluid distributing apparatus of the present invention,, can produce the effect of cancelling out each other because the pressure of fluid is to act on closed core outer circumferential face and the shell inner surface.
Such as, for the cylindrical body core, as shown in figure 15, suppose that the fluid at A place produces pressure F1 to the housing inner peripheral surface, the core outer circumferential face is produced pressure F2, under the effect of F2, core produces directed force F 2 ' to housing, accepts housing simultaneously to its reaction force F2 ", wherein; F1=F2, F2=F2 '=F2 ".Like this, the F1 and the F2 ' that act on housing cancel out each other, and act on the F2 and the F2 of core " also cancel out each other.Similarly, the fluid of other position pressure that acts on housing and core also can produce negative function.Therefore, as long as form the high pressure that the mechanical strength of the material of described core and housing is enough to bear, described fluid distributing apparatus can bear, and does not need to increase extra pressurization or fixing means, and is simple in structure.
