The corrosion-resistant finned tube disclosed by the invention has the characteristics of simple structure, high efficiency, safety and low cost, is easy to assemble and manufacture, and can be widely applied to heat exchange of various corrosive gases in industrial fields.
Description
Technical field
The present invention relates to a kind of finned tube exchanger, relate in particular to and a kind ofly 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 objective of the invention is to deficiency, a kind of corrosion-resistant finned tube is provided to prior art.
The objective of the invention is to realize: a kind of corrosion-resistant finned tube through following technical scheme; 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 invention has the beneficial effects as follows that the corrosion-resistant finned tube of the present invention 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.
