Abstract
The present invention relates to a kind of heat exchange pipe for shell-and-tube heat exchanger and its making process. The high efficiency heat exchange pipe has inward spherical lobes on the high smoothness inner wall. The making process of the high efficiency heat exchange pipe includes the following steps: molding steel plate with high smoothness surfaces to form spherical lobes, cutting into required sizes, and welding the steel stripe into pipe. The spherical lobes distributing in the inner surface of the pipe can produce strong flow swirling and spoiling effect on the heat exchange medium to strengthen heat exchange efficiency and avoid scaling.
Description
Technical field
The present invention relates to a kind of heat exchanger component that is used for diabatic process, especially for the heat exchanger tube of tubular heat exchanger, and the manufacture method of this heat exchanger tube.
Background technology
Tubular heat exchanger is a kind of common heat-exchanger rig.Its basic structure is in casing, and many heat exchanger tubes perhaps are set in shell.For improving the heat exchange efficiency of pipe heat exchanger, also there is employing to replace the structure of the heat exchanger tube of straight wall with the tubing of patterns such as bellows in the prior art.Though use the heat exchanger tube of this class can improve heat exchange efficiency, make the surface of internal and external walls have then difficulty comparatively of higher fineness, particularly require all to reach inside and outside the tube wall fineness of 2B face, it makes very difficulty.In addition, the heat exchanger tube of this class in use easily forms the deficiency of encrustation.When heat transferring medium is high viscosity medium, also can in the ripple of bellows, form retaining of medium, this can further reduce the heat exchange efficiency of device.
Summary of the invention
The invention provides a kind of novel heat exchanger tube with higher heat exchange efficiency.This heat exchanger tube can overcome the deficiencies in the prior art.
Efficient heat-exchanging pipe of the present invention is to be distributed with inwardly protruded hemisphere jut on the inwall of the pipe of best bright finish.
The manufacture method of this efficient heat-exchanging pipe of the present invention is: the steel plate that the two sides is all had high surface finish, the sheet metal of 2B face particularly, mold pressing goes out surperficial hemisphere jut, again on request the heat exchanger tube development size of specification to cut out the sheet metal that own mold pressing goes out hemisphere jut be lath, again the lath moulding is welded into tubing, makes hemisphere jut projecting inward to pipe.The lath moulding can be adopted and revolve the type of being welded into, and also the lath tension and compression can be become tubing, makes hemisphere jut projecting inward to pipe, at last butt seam welding is combined into pipe.Adopting its pipe seam of tubing of tension and compression moulding is vertical masonry joint, can be convenient to carry out the polishing of weld seam.
For welding or the expanded joint requirement of satisfying heat exchanger tube and tube sheet, when the sheet metal compression molding, should leave the welding region of no hemisphere jut apart from the pipe end place.
Interval between the radius of hemisphere jut arrangement of the present invention, each hemisphere jut, the height of each hemisphere jut and each hemisphere jut should be determined according to the process conditions of different heat transferring mediums.
The present invention has following advantage:
1, heat exchanger tube of the present invention is owing to be to have adopted the 2B face thin-walled steel plate materials with high surface finish, and two surfaces of this 2B face thin-walled steel plate materials are all through polishing, its peculiar high surface finish can full-bodied MEDIA FLOW through the time be difficult for to produce apposition, therefore be specially adapted to the high viscosity medium heat exchange.
2, because the inwall of pipe is distributed with hemisphere jut, can produce the strong flow-disturbing effect of revolving to the heat transferring medium that passes through, strengthened heat exchange efficiency.
3, because the flow-disturbing effect of revolving that the hemisphere jut that inside pipe wall distributes produces makes its effect with self-cleaning heat exchange surface, therefore can prolong the cycle that heat exchanger cleans.The hemisphere jut of surface distributed makes the flowing liquid membrane disturbance and forms turbulent flow on the other hand, this flow regime just was difficult for making heat transferring medium in the fouling of heat exchange wall originally, the hemisphere jut of adding surface distributed also can make the dirt layer be difficult for continuously, thereby discontinuous dirt layer heat transferring medium constantly wash away and the effect of little vibration during the equipment operation under, dirt layer easily generation comes off voluntarily, has further prolonged the cycle that heat exchanger cleans.
4, the hemisphere jut of inwall distribution is recessed sphere corresponding to outer wall, also can form strong disturbance to managing flowing of the outer medium that flows, and the turbulent flow of fluid is strengthened.
5, the hemisphere jut heat exchanging of inwall distribution plays invigoration effect, but the resistance drop that produces is very little, therefore can not have a negative impact to the mobile of liquid.
6, the present invention is applied to large tubular and falls in (liter) film evaporator, and concavo-convex alternate heat-transfer surface not only can make the condensate film attenuate on its tube wall, and can make the condensate film disturbance form turbulent flow, thereby reaches the purpose of augmentation of heat transfer.
7, the more existing bellows manufacturing process of heat exchanger tube manufacturing process of the present invention is more simple, and cost also can be lower.
8, heat exchanger tube manufacturing process of the present invention adopts lath tension and compression technological forming, is convenient to carry out polishing through the weld seam that welds formed tubing again, and its use has best effect.
Description of drawings
Accompanying drawing 1 is a heat exchanger tube generalized section of the present invention.Accompanying drawing 2 is the schematic diagram of the left apparent place of accompanying drawing 1.Accompanying drawing 3 launches schematic diagram for tube wall.
The specific embodiment
The present invention is below in conjunction with description of drawings:
Heat exchanger tube manufacture method of the present invention is earlier will be by the 2B face sheet metal mold pressing surface hemisphere jut of designing requirement thickness specification, and the radius of its hemisphere jut, distribution and each protruding spacing should be determined according to different media and heat-exchanging process.When carrying out the sheet metal mold pressing, there is not hemisphere jut apart from pipe end certain-length scope planted agent, with welding or the expanded joint requirement of satisfying heat exchanger tube and tube sheet.The heat exchanger tube development size of specification is cut out the sheet metal lath of own mold pressing on request again, forms lath as shown in Figure 3.
Again the lath tension and compression are become tubing, and the seam pipe seam, preferably adopt the high frequency seam, form heat exchanger tube.
And then the technology of pressing prior art combines each heat exchanger tube the formation heat exchanger with tube sheet.
