Fig. 2 is the perspective view of the oval flat spiral heat exchange tube in embodiment illustrated in fig. 1.
Fig. 3 is the local structure for amplifying sketch map of A-A portion among Fig. 2.
The specific embodiment
Below will combine accompanying drawing that the technique effect of design, concrete structure and the generation of the utility model is described further, with purpose, characteristic and the effect of understanding the utility model fully.
Evaporimeter mainly partly is made up of device body, heat exchanger tube etc.As shown in Figure 1, a kind of evaporimeter of using oval flat spiral heat exchange tube of present embodiment mainly comprises device body and at least one heat exchanger tube, evaporating liquid steam-gas inlet 4, evaporating liquid vapor outlet port 5, and other associated conduit.
The special feature of the utility model is that heat exchanger tube is oval flat spiral heat exchange tube 1.Like Fig. 2, shown in Figure 3, the oval flat spiral heat exchange tube 1 in the utility model, its main body is the body of a metal, especially, is the metal welded tube in the present embodiment.Body surrounds and forms the medium channel that a confession heat transferring medium circulates therein, with the heat exchange of medium inside and outside the realization body.
In the utility model, body is by the special-shaped pipeline section 10 that is positioned at the middle part, and first straight length 11, second straight length, 12 one that lay respectively at special-shaped pipeline section 10 two ends constitute.
Abnormity pipeline section 10 has oval flat cross section, and this long axis of ellipse has a rotation angle with the axis of the relative body of minor axis.
In the present embodiment, the length of the major axis of special-shaped pipeline section 10 is greater than the diameter of body.
Further, first straight length 11 and second straight length 12 are isometric for not.Its beneficial effect is; The oval flat spiral heat exchange tube of the utility model is when being used to assemble evaporation equipment; Because the pitch space of tube sheet is limited, adopt the not isometric straight length in two ends, when assembling just in the past an end by means of size; To make full use of the space between the tube sheet, improved the convenience that evaporation equipment is installed.
Certainly, in the ordinary course of things, also can adopt first straight length 11 and second straight length 12 for isometric.
Particularly, in different embodiment, above-mentioned rotation angle can be for clockwise, also can be for counterclockwise.
The rotation angle can be chosen according to actual conditions in 75 ° at 1 °.Generally speaking, the size of rotation angle is relevant with the length of body, and the length of body is long more, and the rotation angle that can take is also just big more.Selecting for use of above-mentioned various rotation angles, also relevant with the hydrodynamics attribute of heat transferring medium, be not restriction to the utility model.
The technique scheme of the utility model applicable to stainless steel straight collimator (seamless steel pipe), is particularly useful for the metal welded tube.
Oval flat spiral heat exchange tube in the utility model is not also owing to have cold working after the tubulation moulding, so internal structure stress eliminates basically, and anti-fouling tendency, corrosion resistance are better.The utility model also has simple in structure, and cost is low, makes more beneficial effect such as facility.
According to client's needs, the entire length of the oval flat spiral heat exchange tube in the utility model can be chosen between tens of rice at 0 meter.Certainly, if the reasonable disposition heat-treatment furnace, the entire length of the oval flat spiral heat exchange tube in the utility model can also be in random length, and is not subject to the specification of cold working equipment.
Process conditions, the structural safety that perfect evaporimeter should satisfy reasonably to realize defined when design or type selecting be reliable, be convenient to make, installation, Operation and maintenance and economically rationally.Therefore, in the design process of evaporimeter, give one's full attention to the harmony of each parameter.
Oval flat spiral heat exchange tube has constituted the heat-transfer area of evaporimeter, and the size and dimension heat exchanging of oval flat spiral heat exchange tube has very big influence.When adopting the heat exchanger tube of minor diameter, the heat exchange area of evaporimeter unit volume is big, and equipment is compact, and the metal wastage of unit heat transfer area is few, and heat transfer coefficient is also higher.Therefore, to the large diameter heat exchanger tube of the general selection of the big perhaps dirty fluid of viscosity, the fluid that cleans is generally selected the heat exchanger tube of minor diameter.
The parameter of the material of heat exchanger tube is selected and should be confirmed according to pressure, temperature and the corrosivity of medium.
The arrangement of heat exchanger tube on the device body singly will do not considered the compactedness of equipment, also will consider the situation of character, structural design and the processing and manufacturing aspect of fluid.
The selection of heat exchanger tube centre-to-centre spacing should be considered the compactedness of structure on the device body, and heat-transfer effect is considered the intensity and the required space of scavenging duct outer surface of device body again.
In addition, also need consider the fixing means of heat exchanger tube on the device body.If spacing is too little, when employing was welded to connect, the weld seam of adjacent two heat exchanger tubes was too near, and weldquality is influenced by heat and is difficult to obtain assurance; If adopt expanded joint, extruding force possibly cause the device body that excessive distortion takes place, and loses the adhesion between heat exchanger tube and device body.The centre-to-centre spacing of the general heat exchanger tube that adopts is not less than 1.25 times of heat exchanger tube external diameter.
In other embodiments, oval flat spiral heat exchange tube also can be made U type or S type as required.
A kind of heat transferring medium that only circulates in the evaporimeter of the oval flat spiral heat exchange tube of above-mentioned various application of the utility model, with other outer Medium Exchange heats of evaporimeter.
The oval flat spiral heat exchange tube that the utility model uses is compared with other structure heat exchanger tubes of equivalent diameter in the prior art; Though cross-sectional area is identical; But the flow-disturbing effect is obvious in the oval flat spiral heat exchange tube, and its heat exchange efficiency greatly improves, and has also further reduced the energy consumption of evaporimeter.
The oval flat spiral heat exchange tube that the utility model uses because the flow-disturbing effect in the pipe, less scaling, the anti-tartar performance is good, so the evaporimeter of the utility model also have less scaling, the characteristics that the anti-tartar performance is good.
In sum, the just several kinds of preferred embodiment of the utility model described in this specification, above embodiment is only unrestricted in order to the technical scheme of explanation the utility model.All technical staff in the art according to the design of the utility model on the basis of existing technology through the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be within the claim protection domain of the utility model.
