Description
Technical field
The present invention relates to a kind of titanium double-tube heat exchanger.
Background technology
Material selection in general heat exchanger for stainless steel plate or other, in order to ensure the high intensity of heat exchanger, its material
Can be thicker, it is integrally heavier which results in heat exchanger, and when running into corrosive medium, material holds
Easily it is corroded and medium mixing occurs, heat exchanger is scrapped.Simultaneously because contain many mineral matters in water, for a long time using can exchange heat
Incrustation scale is formed in device, the accumulation of incrustation scale can increase thermal resistance, reduce the heat exchange efficiency of heat exchanger.
The content of the invention
The present invention relates to a kind of titanium double-tube heat exchanger, above mentioned problem can solve the problem that.
To realize this purpose, the method applied in the present invention is：A kind of titanium double-tube heat exchanger, including outer tube, it is described outer
Titanium inner helix pipe is provided with pipe, and the titanium inner helix pipe is the helical tubular structure using titanium as material, spiral shell in the titanium
The both ends of coil connect water route outlet and waterway inlet, the water route outlet and waterway inlet and titanium inner helix pipe junction respectively
Outside be respectively equipped with a steel bushing, be connected with fluorine road entrance on the steel bushing in water route exit, connected on the steel bushing at waterway inlet
There is the tubular structure in fluorine way outlet, fluorine road entrance and fluorine the way outlet gap between connection outer tube and titanium inner helix pipe.
A steel copper composite ti pipe is respectively provided between the steel bushing and water route outlet and waterway inlet.
Described its tube wall of titanium inner helix pipe is 0.8mm.
A kind of method for processing above-mentioned titanium inner helix pipe, using the thick seamless titanium tube rotary press modellings of 0.8mm, during spinning
Seamless titanium tube thick 0.8mm is lined with SPCC welded still pipes, divides SPCC welded still pipes and the titanium inner helix pipe of shaping after spinning
From.
The thickness of the SPCC welded still pipes is 2mm.
Its advantage is：Fluorine and water segregation are opened using titanium tube, titanium tube light weight, intensity is high, and mechanical performance is superior, high
There is excellent decay resistance under warm high pressure, and the heat exchange mode of surface and steam is dropwise condensation, reduces hot group, titanium tube
Surface non-scaling can also reduce thermal resistance, and the heat exchange property of titanium tube is notable.Titanium tube works in seawater, acid medium, and its is anticorrosive
Property is better than stainless steel；It is also especially strong to the resistance of spot corrosion, acid etching, stress corrosion, and used titanium inner helix pipe is adding
Greatly promoted when work by the use of SPCC steel pipes as support, its yield rate.
Brief description of the drawings
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein：
Fig. 1 is sectional structure chart of the present invention.
Embodiment
All features disclosed in this specification, or disclosed all methods or during the step of, except mutually exclusive
Feature and/or step beyond, can combine in any way.
This specification（Including any accessory claim, summary and accompanying drawing）Disclosed in any feature, except non-specifically chatting
State, can alternative features equivalent by other or with similar purpose replaced.I.e., unless specifically stated otherwise, each feature
It is an example in a series of equivalent or similar characteristics.
A kind of titanium double-tube heat exchanger as shown in Figure 1, including outer tube 4, the outer tube 4 is interior to be provided with titanium inner helix pipe 5, described
Titanium inner helix pipe 5 is the helical tubular structure using titanium as material, and the both ends of the titanium inner helix pipe 5 connect water route respectively
Outlet 3 and waterway inlet 7, the water route outlet 3 and waterway inlet 7 on the outside of the junction of titanium inner helix pipe 5 with being respectively equipped with one
Steel bushing 2, water route are exported and fluorine road entrance 1 are connected with the steel bushing at 3, and fluorine way outlet 6 is connected with the steel bushing at waterway inlet 7,
The tubular structure in fluorine road entrance 1 and fluorine way outlet 6 gap between connection outer tube 4 and titanium inner helix pipe 5.The steel bushing 2 and water
A steel copper composite ti pipe 8 is respectively provided between way outlet 3 and waterway inlet 7.Titanium tube light weight, intensity is high, and mechanical performance is superior, high
There is excellent decay resistance under warm high pressure, and the heat exchange mode of surface and steam is dropwise condensation, reduces hot group, titanium tube
Surface non-scaling can also reduce thermal resistance, and the heat exchange property of titanium tube is notable.Titanium tube works in seawater, acid medium, and its is anticorrosive
Property is better than stainless steel；Also especially strong to the resistance of spot corrosion, acid etching, stress corrosion, described its tube wall of titanium inner helix pipe 5 is
0.8mm。
Because the intensity of titanium tube is high, tube wall holding power is not enough easily wrinkled, ruptured during cold working, and yield rate is relatively low, and this
Invention is lined with SPCC welding steel during spinning using seamless titanium tube rotary press modelling thick 0.8mm in the thick seamless titanium tubes of 0.8mm
Manage, separate SPCC welded still pipes with the titanium inner helix pipe being molded after spinning, the thickness of SPCC welded still pipes is 2mm, thus
Titanium tube can be avoided to wrinkle or rupture, improve the yield rate of processing.
The invention is not limited in foregoing embodiment.The present invention, which expands to, any in this manual to be disclosed
New feature or any new combination, and disclose any new method or process the step of or any new combination.
