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.
Embodiment 1:
Condenser mainly partly is made up of tube sheet, tube bank, condenser pipe etc.As shown in Figure 1, the condenser of arc heat exchanger tube is revolved in a kind of application of present embodiment, mainly comprises tube sheet 4 and at least one condenser pipe, also comprises device for drying and filtering 6, capillary 7, evaporimeter 8 etc.
The special feature of the utility model is that condenser pipe has medium inlet and media outlet for revolving arc heat exchanger tube 1.Revolve arc heat exchanger tube 1 and be directly connected to refrigeration compressor 5.
As shown in Figure 2, the arc heat exchanger tube 1 that revolves in the utility model is one to have the metal welded tube of certain-length, like austenitic stainless steel welded tube, carbon steel welded tube, titanium or titanium alloy welded tube, nickel and nickel alloy welded tube, or austenite-ferrite dual phase steel welded tube etc.
The body that revolves arc heat exchanger tube 1 surrounds and forms a medium channel, and body is the integrative-structure of a special-shaped pipeline section and first straight length 11 and second straight length 12.
Be formed with the groove 31 that many arcs extend on the tube wall of this abnormity pipeline section.Many groove 31 is parallel to each other, with the axis formation one rotation angle of body.Groove 31 is remarkable to the condensation performance impact of revolving the arc heat exchanger tube with the rotation angle of the axis of body.The rotation angle can be chosen between 1 ° to 75 ° according to factors such as air flowability and calibers.Preferably, can select between 5 ° to 60 °.
In the present embodiment, the cross section of groove 31 is an arc.In other embodiments, also can be triangle or isosceles trapezoid.
In order to improve the assembling effect, first straight length 11 and second straight length 12 are isometric for not, so that can borrow in installation, make full use of the space between the tube sheet.
Revolve the arc heat exchanger tube also owing to do not have cold working after the tubulation moulding in the utility model, so internal structure stress eliminates basically, 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 revolving the arc heat exchanger 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 revolving the arc heat exchanger 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 condenser 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 condenser, give one's full attention to the harmony of each parameter.
Revolve the heat-transfer area that the arc heat exchanger tube has constituted condenser, the size and dimension that revolves the arc heat exchanger tube has very big influence to condensation.When adopting the condenser pipe of minor diameter, the condensation area of condenser 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 condenser pipe of the general selection of the big perhaps dirty fluid of viscosity, the fluid that cleans is generally selected the condenser pipe of minor diameter.
The parameter of the material of condenser pipe is selected and should be confirmed according to pressure, temperature and the corrosivity of medium.
The arrangement of condenser pipe on tube sheet 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 condenser pipe centre-to-centre spacing should be considered the compactedness of structure on the tube sheet, and heat-transfer effect is considered the intensity and the required space of scavenging duct outer surface of tube sheet again.
In addition, also need consider the fixing means of condenser pipe on tube sheet.If spacing is too little, when employing was welded to connect, the weld seam of adjacent two condenser pipes was too near, and weldquality is influenced by heat and is difficult to obtain assurance; If adopt expanded joint, extruding force possibly cause tube sheet that excessive distortion takes place, and loses the adhesion between condenser pipe and tube sheet.The centre-to-centre spacing of the general condenser pipe that adopts is not less than 1.25 times of condenser pipe external diameter.
Embodiment 2:
The another embodiment of the utility model, basic identical with the foregoing description, institute's difference is, like Fig. 3, shown in Figure 4, that has adopted a linear revolves arc heat exchanger tube 1, surrounds to form a medium channel 2.Be formed with the groove 31 that arc extends on the tube wall, groove 31 correspondingly is formed with protruding arc lines 32 at the inwall of body.
In other embodiments, revolve the arc heat exchanger tube and also can make U type or S type as required.
A kind of cooling medium that only circulates in the condenser of arc heat exchanger tube is revolved in the above-mentioned various application of the utility model, with other outer Medium Exchange heats of condenser.
The arc heat exchanger tube that revolves 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 it is obvious to revolve the interior flow-disturbing effect of arc heat exchanger tube, and its condensation efficiency greatly improves, and has also further reduced the energy consumption of condenser.
The utility model uses revolves the arc heat exchanger tube, because the flow-disturbing effect in the pipe, less scaling, the anti-tartar performance is good, thus the condenser 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.
