Embodiment described in composition graphs 1-3 is described by current divider 92, and wherein each current divider comprises base portion, and base portion generally represents by 35, and one group of pipeline 24,26,28,30 extends from base portion.Each pipeline 24,26,28,30 has bending " ancon " shape design and is connected to respective service 16,18,20,22.Each service 16,18,20,22 is connected to A type triangle part 12,14, and is communicated with A type triangle part 12,14 fluid, and more properly, is connected to finned tube bundle 15, and is communicated with finned tube bundle 15 fluid.
Current divider 92 is configured to two parts or region, and these two parts or region have geometry different from each other or design.Current divider 92 has base portion or region 34 under column, and wherein the main flow of industrial fluids enters described current divider 92.Lower base portion or region 34 are transitioned into diffusion zone 36, and diffusion zone 36 has roughly foursquare geometry.As shown in Figure 3, diffusion part 36 comprises several hole or port, and hole or port and elbow pipeline 24,26,28,30 coincide, and allows industrial fluids through its flowing.Typical aerial condenser utilizes current divider 32 be connected to the lifting device on it and therefore allow industrial fluids, such as steam, flows through there.This lifting device is connected to main steam line.
By switching the Inlet and outlet pipe extended from described current divider 92, current divider 92 plays separately and/or merges the effect of stream.According to size and application, current divider 92 can separate or merge the stream of any amount.And current divider 92 can adopt the guide vane in base portion 34 and/or be conducive to the diffusion zone 36 of thermal losses minimizing.Equally, elbow pipeline can in design with geometrically different.Such as, some embodiments can adopt the elbow pipeline of standard, or the elbow pipeline of short elbow pipeline or mitered.
With reference now to the current divider represented by Reference numeral 94, described current divider is similar to the embodiment shown in Fig. 4, and is described by composition graphs 4.But the diverter designs shown in Fig. 1-3 adopts the current divider 40 shown in four elbow pipelines 24,26,28,30, Fig. 4 to adopt two elbow pipelines 46,48.Current divider 92 has base portion 42 or region under column, and wherein the main flow of industrial fluids enters described current divider 92.Guide vane in lower base portion 34 and/or be conducive to thermal losses reduce diffusion zone 36.Equally, elbow pipeline can in design with geometrically different.Such as, some embodiments can adopt the elbow pipeline of standard, or the elbow pipeline of short elbow pipeline or mitered.
In location in figs. 8 and 9, distribution of steam is arranged such that central tube 88,90 has identical diameter.In shown location, central tube operation is to supply the half road of steam to the opposite side of a road of the side of central tube and central tube.Therefore, a central tube supplies two modules of each central tube, then alternately to a module of every side, like this.
With reference now to Figure 10 and 11, the design (usually representing by 200) of quick union is illustrated.Quick union comprises neck ring 210 and is resisted against neck ring 210 and the inner seal 212 of being fixed by neck ring 210.Inner seal 212 is diametrically being roughly circle, and has containment member 214, such as O ring etc., and containment member 214 provides the sealed engagement between two pipelines, and it will be discussed further following.As shown in Figures 10 and 11, neck ring 210 comprises two halves or two pieces 216,218, and two halves or two pieces 216,218 are connected by the revolving part in neck ring one end or hinge 220.Neck ring 210 also comprises by the sealing attachment arrangement of attachment means 222 in every side of the other end.This attachment means 222 can regulate, and in one embodiment, is preferably the combination of nut and screw.
Because typically aerial condenser runs under vacuum, therefore all connections obviously need airtight and reliable.The most general mode of airtight connection is provided to be pipe or pipeline are welded together.Quick union design is the replacement of welding.Therefore, during operation, neck ring 210 catches the flange of two pipelines 224,226, and wherein containment member plays the effect of the end around each respective pipeline.By adjustable attachment means 222, neck ring 210 is sealed in around described containment member then, by line seal together.In several joint application, such as condensing line, air flow out circuit and steam line, and quick union can be employed on aerial condenser.Quick union can be installed by the personnel that experience is less, instead of needs welding, and this is very important, especially as the crew shortage be skilled in technique.
At run duration, typically, the turbine back pressure of aerial condenser etc. limits by the maximum vapor (steam) velocity in pipe that ((to limit erosion), wherein vapor (steam) velocity reduces along with back pressure and increases (due to vapour density).Like this, additional in conjunction with diverter designs due to pipe as described in the present invention, steam still maintains maximum allows vapor (steam) velocity, and is in lower back pressure.Another restriction that existing triangle part design presents is that the pressure in the exit of secondary bundle can not be less than vavuum pump capacity.This pressure typically deducts by eddy current back pressure the pressure drop that ducted pressure drop deducts in pipe to be caused.Therefore, due to the pressure drop reduced in pipe, adopt the aerial condenser design proposed, the turbine back pressure of allowing is lower.
In addition, the mean temperature difference between above-mentioned bundle exchange surface.Due to the pressure drop reduced as elucidated before, average pressure (the mean temperature difference between entrance and exchange surface in the heat exchanger of the aerial condenser design adopting this to propose.Due to the pressure drop reduced as elucidated before, the average pressure (between inlet pressure and outlet pressure mean value) in the heat exchanger of the aerial condenser design adopting this to propose is higher.Change sentence to change, because steam is saturated, the average steam temperature of identical heat exchange surface is also higher, and causing increases heat exchange.
Alternatively, above-mentioned embodiment of the present invention adopts the tube bank manufacturing and assemble, and before shipment, have steam manifold and steam-condensation head, the embodiment of replacement can not have manifold before shipment.More specifically, in such embodiment, tube bank can be transported and not have manifold thereon.In said embodiment, tube bank can be assembled in place to form A type structure, as mentioned above.But substitute employing two steam manifold, this embodiment replaced can adopt single steam manifold, and wherein single steam manifold extends along " summit " that A constructs.
With reference now to Figure 12 and 13, according to replacement embodiment of the present invention, T-piece or current divider 300 are illustrated.As shown in Figures 10 and 11, current divider 300 has main columnar part or matrix 302, and main columnar part or matrix 302 provide flowing entrance.Current divider 300 also comprises the first and second flow branch, and each branch is connected to main columnar part 302, and extends from main columnar part 302.Described flow branch 304,306 has the geometry being similar to truncated conical region, and 304 and 306 respectively, have first area, and first area has the first diameter being transitioned into second area, and second area has less diameter.As shown in Figures 10 and 11, flow branch part 304,306 can be described to the merging of the flow region with "T"-shaped shape and " Y " shape or combination or fusion alternatively.Equally as shown in Figures 10 and 11, current divider 300 comprises and is attached to 304,308 and 310 of respective branch 304,306.Described columnar part 308,310 has the diameter being less than intake section 302 diameter.
Above-mentioned design needs less manufacturing time, and provides the lighter design of permission less fluid side pressure drop equally.This solution proposed also should be cut member more simply and again be welded at the scene.Therefore, current parts should be easily manufactured, because it is by simple piece construction.And at run durations such as aerial condensers, above-mentioned current divider 200 designs minimum steam side pressure drop.
