Description
Technical field
The utility model relates to heat exchanger tube technical field more particularly to a kind of efficient heat transfer anticorrosion heat exchanger tubes.
Background technique
The heat exchanger tube of existing application on heat exchangers, there are two types of styles, a kind of heat exchange copper tube, it has, and price is low, welds
The good advantage of property, but there are the deficiencies of poor corrosion resistance, especially as heat exchanger tube in use, in view of Jie for flowing through its lumen
Matter has part that there is stronger corrosivity therefore to limit the use of heat exchanger tube to a certain extent；Another kind heat exchange titanium tube,
Although it has corrosion resistance high, the good advantage of thermal conductivity, there are price is rather stiff, the deficiency of weldability difference is especially made
For heat exchanger tube in use, heat exchange titanium tube is not easy to weld with outside, even if welding, also insecure, it is be easy to cause separation, significantly
The service life of heat exchanger is reduced, and repair rate is high.In addition, pipe wall of heat exchange pipe uneven heating is even, and then influence heat exchanger tube heat exchange
Effect.
Summary of the invention
The utility model aims to solve the problem that the deficiencies in the prior art, and provides a kind of efficient heat transfer anticorrosion heat exchanger tube.
In order to achieve the above object, the utility model adopts the following technical solutions: a kind of efficient heat transfer anticorrosion heat exchanger tube, packet
The truncated cone-shaped heat exchange pipe body of inner hollow is included, one end that heat exchange pipe body is relatively large in diameter is equipped with air inlet, and heat exchange pipe body is straight
The lesser one end of diameter is equipped with gas outlet, and air inlet and air outlet are connected to heat exchange pipe body inner cavity, and air inlet and air outlet are leaned on
The one end for connecing heat exchange pipe body is equipped with oxygen-free copper layer, and heat exchange pipe body inner wall is equipped with corrosion-resistant coating, heat exchange pipe body outer wall
It is arranged with copper pipe, the outside of copper pipe is equipped with spiral fin, and copper, the copper pipe between spiral fin have been crossed in the surface layer of fin
Several cambered surface grooves are uniformly provided on wall, gas outlet is connect with external air-introduced machine.
Corrosion-resistant coating is ceramic coating.
Heat exchange pipe body is anti-corrosion alloy steel.
The beneficial effects of the utility model are: the corrosion-resistant coating of the utility model can prevent from entering in heat exchange pipe body
Gas attack heat exchange pipe body inner wall, recuperated gas, which enters in the truncated cone-shaped structure of heat exchange pipe body, keeps heat exchange pipe body heated equal
Even, the fin, copper pipe and cambered surface groove for crossing copper improve the heat transfer efficiency of the utility model, good heat conduction effect.In addition, anaerobic
The welding effect of layers of copper is good, and the utility model is welded on tube sheet by oxygen-free copper layer, time saving and energy saving.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
In figure: 1- heat exchange pipe body；2- air inlet；The gas outlet 3-；4- corrosion-resistant coating；5- oxygen-free copper layer；6- fin；7- copper
Pipe；8- cambered surface groove；
It is described in detail below with reference to the embodiments of the present invention referring to attached drawing.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples:
As shown in Figure 1, a kind of efficient heat transfer anticorrosion heat exchanger tube, the truncated cone-shaped heat exchange pipe body 1 including inner hollow, are changed
One end that heat pipe body 1 is relatively large in diameter is equipped with air inlet 2, and the lesser one end of 1 diameter of heat exchange pipe body is equipped with gas outlet 3, air inlet
Mouthfuls 2 and gas outlet 3 be connected to 1 inner cavity of heat exchange pipe body, one end that heat exchange pipe body 1 is abutted against in air inlet 2 and gas outlet 3 is all provided with
There is oxygen-free copper layer 5,1 inner wall of heat exchange pipe body is equipped with corrosion-resistant coating 4, and 1 outer wall of heat exchange pipe body is arranged with copper pipe 7, copper pipe 7
Outside is equipped with spiral fin 6, and the surface layer of fin 6 has been crossed copper, has been uniformly provided on 7 wall of copper pipe between spiral fin 6
Several cambered surface grooves 8, gas outlet 3 are connect with external air-introduced machine.
Corrosion-resistant coating 4 is ceramic coating.
Heat exchange pipe body 1 is anti-corrosion alloy steel.
When utility model works, recuperated gas enters in heat exchange pipe body 1 from the air inlet 2 of heat exchange pipe body 1, will
Heat passes to heat exchange pipe body 1 through corrosion-resistant coating 4, and heat exchange pipe body 1 is transferred heat to again on copper pipe 7 and its copper pipe 7
Fin 6 carries out heat exchange to external.Corrosion-resistant coating 4 can prevent the gas attack heat exchanger tube sheet entered in heat exchange pipe body 1
1 inner wall of body, recuperated gas, which enters in the truncated cone-shaped structure of heat exchange pipe body 1, is heated evenly heat exchange pipe body 1, crosses the wing of copper
Piece 6, copper pipe 7 and cambered surface groove 8 improve the heat transfer efficiency of the utility model, good heat conduction effect.In addition, the weldering of oxygen-free copper layer 5
It is good to connect effect, the utility model is welded on tube sheet by oxygen-free copper layer 5, it is time saving and energy saving.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, if the method concept of the utility model and the various improvement of technical solution progress are used, or without
Improvement directly applies to other occasions, both is within the protection scope of the present invention.
