The corrosion-resistant finned tube has the characteristics of simple structure, high efficiency, safety, easiness for combination and fabrication, low cost and the like, and can be widely applied in the industrial field for heat exchange of various corrosive gases.
Description
Technical field
The utility model relates to a kind of finned tube exchanger, relates in particular to a kind ofly to can be applicable to corrosive gas and liquid carries out anticorrosion finned tube of high efficient heat exchanging and preparation method thereof.
Background technology
The gas that the industrial circle discharging is a large amount of contains great amount of heat in these gases, and contains corrosive substance and dust etc. in the gas, like the flue gas of discharged from coal-fired boiler.Conventional finned tube exchanger; No matter be longitudinal fin or transverse fin or spiral fins, because fin shape is complicated, factor such as number of fins is many; All be unfavorable for exchanging heat pipe and fin carries out surface treatment simply and effectively or protection, thereby can't realize functions such as anticorrosion accumulatingdust.
Therefore be necessary to seek a kind of gas-liquid heat-exchange of fin efficiently that stops up with dust that can effectively prevent to corrode.
Summary of the invention
The purpose of the utility model is the deficiency to prior art, and a kind of corrosion-resistant finned tube is provided.
The purpose of the utility model realizes through following technical scheme: a kind of corrosion-resistant finned tube; It comprises metal tube and metal fin; Metal fin links to each other with the metal tube both sides, and parallel with metal tube, around metal tube, pastes diaphragm; Over cap perhaps is installed, is perhaps pasted diaphragm and over cap simultaneously.
Further, described metal fin is the shape of sealing, be filled with in it Heat Conduction Material with in the material of corrosive substance in one or both.
Further, described metal tube and fin surface have erosion shield.
Further, the connected mode of described metal tube and fin is welding.
Further, the connected mode of described metal tube and fin is a mechanical interlocking.
Further, described over cap is plastics, metal or pottery etc., be filled with in the over cap Heat Conduction Material with in the material of corrosive substance in one or both.
The beneficial effect of the utility model is, that the corrosion-resistant finned tube of the utility model has is simple in structure, highly effective and safe, be easy to make up, make characteristics easy, with low cost, can be widely used in the heat exchange of the various corrosive gas of industrial circle.

The specific embodiment
Describe the utility model in detail according to accompanying drawing and embodiment below, it is more obvious that purpose of the utility model and effect will become.
Embodiment 1
As shown in Figure 1, there is metal fin 20 metal heat exchanger tube 10 both sides, and both connect through welding manner, promptly connect through pad 21.Around heat exchanger tube 10, paste layer protecting film 31, protect with the exchange heat pipe, to prevent that liquid is revealed because of corrosion in the heat exchanger tube, diaphragm 31 can be fluoroplastics, and like polymeric membranes such as PTFE films, the connection of film adopts adhesive to connect.Heat exchanger tube 10 also has layer of protecting property coating with fin 20 surfaces, like enamel coating, and not expression among Fig. 1 and Fig. 5.
Embodiment 2
Fig. 2 representes the structure of another kind of fin heat exchange pipe; The diaphragm 31 that is about among Fig. 1 is transformed to over cap 32; Its thickness is generally greater than diaphragm 31, and the material of over cap 32 can be metal, macromolecular material, pottery etc., and the connected mode of over cap 32 can be mechanical interlocking; Mode such as bonding adopts mechanical locking device 33 to connect shown in Fig. 2.Can fill the thermal conductivity material in the over cap 32, like graphite powder etc.; Also can fill can in the composition of corrosive substance; As preventing the corrosion of sulfur-containing smoke gas, filler can also can be filled above-mentioned two kinds of materials simultaneously for lime etc.
Also can Fig. 1 be combined with Fig. 2 dual mode, promptly after pasting layer protecting film 31, add over cap 32 again, or after adding over cap 32, paste layer protecting film 31 more above that.
Embodiment 3
As shown in Figure 3; Fin among Fig. 2 20 and over cap 32 are united two into one; Fin 20 comprises first fin 26 and second fin 27; First fin 26 and second fin 27 are the shape of sealing, and the mode through machining makes first fin 26 that metal tube 10 parcels are tight, and second fin 27 links to each other with first fin 26.Can fill it in first fin 26 and second fin 27 the thermal conductivity material is arranged.Like graphite powder etc.With the composition of corrosive substance, as prevent the corrosion of sulfur-containing smoke gas in also can being filled with, filler can be for lime etc., also can fill above-mentioned two kinds of materials simultaneously.
Embodiment 4
As shown in Figure 4, fin 20 is filled with Heat Conduction Materials such as conductive powder for the shape of sealing, or in being filled with the material of corrosive substance, or fill above-mentioned two kinds of materials simultaneously.Over cap 32 is arranged around the metal heat exchanger tube 10, and over cap 32 is filled by resistant material and is formed.
