Abstract
The utility model discloses a graphite vertical finned tube smog heat exchanger, pertaining to a heat exchange equipment, in particular to a common spare part for heat exchange or heat transfer equipment. The graphite vertical finned tube smog heat exchanger includes a tube and a connector. The utility model is characterized in that: the tube is constituted by a graphite inner tube and a graphite fin distributed along the longitudinally on the external surface; both ends of the graphite tube are provided with a metal connector. The heat tube is made of graphite and both ends are provided with the metal connector, graphite is a non-metallic material of the best heat conductivity, the coefficient of heat conductivity is about twice as steel and graphite also has good corrosion resistance; in addition, the metal connector also solves the connecting problem with the tube box; therefore, the utility model of the graphite vertical finned tube smog heat exchanger has the advantages of high heat exchange efficiency, corrosion resistance, small smog resistance, large cross-sectional flow area, small size, difficult fouling, small demand for fan power, energy saving and convenient maintenance.
Description
Technical field
The utility model belongs to a kind of heat-exchange apparatus, the parts of particularly a kind of interchangeable heat exchange or heat-transfer equipment.
Background technology
The generally well-known smoke heat replacing device that generally is used for desulfurization project, in its heat exchanger tube with water as heat transfer medium, in order to strengthen the heat transfer of fume side, make the heat-exchanger rig compact conformation, install fin additional in heat exchanger tube tube bank outside usually, adopt the stagger arrangement arrangement, the shortcoming of this smoke heat replacing device is that the fume side resistance is bigger, dust stratification stops up easily, and structure is not compact, causes equipment cost and operating cost all than higher.CN2682368 discloses a kind of longitudinal finned tube smoke heat replacing device that can cool off or heat flue gas in the boiler exhaust gas desulfurization project.It comprises heat exchanger tube, little collection case, collects case and shell greatly, and its heat exchanger tube is made up of interior pipe and fin, and the outer surface of interior pipe radially is evenly equipped with a plurality of fins radially; Each fin extends along the straight line that vertically carries out of interior pipe.Because this utility model adopts longitudinal finned tube as heat exchange element, cool off or the flue gas that heats vertically flowing of finned tube longitudinally, its flue gas flow channel is axial through type, and parallels with the flow path of heat transferring medium water, it is little to have flue gas resistance, is difficult for dust stratification and obstruction; The outer rim shaped design of radially analysing and observe of longitudinal finned tube is a rectangle, and heat exchanger tube can closely be arranged, and not only compact equipment more makes flow of flue gas unobstructed, the heat transfer efficiency height.But be to use middle the discovery because the use aluminum is made heat-transfer pipe, poor corrosion resistance is not suitable for containing in the flue gas user's use of the stronger gas of various corrosivity.
The utility model content
It is unobstructed that the purpose of this utility model provides a kind of flow of flue gas, the technical scheme of the novel longitudinal fin flue gas heat exchange tube of heat transfer efficiency height and corrosion-resistant long service life.
The technical solution of the utility model is, a kind of graphite longitudinal fin flue gas heat exchange tube, this heat exchanger tube comprises body, joint, and its structure is: described body is made up of the graphite fins that longitudinally distributes on pipe and the outer surface in the graphite, and metal joint is equipped with at the pipe two ends in the graphite.
Between the external screw thread of the internal thread of pipe and metal joint adhesive layer is arranged in described.
Pipe internal surface is the light face or vertical fin is arranged in the described graphite.
The described body cross section of being made up of the graphite fins that longitudinally distributes on pipe and the outer surface in the graphite is that circular inner tube outer surface is equipped with the graphite fins that longitudinally distributes radially, the terminal line track of fin is circle or rectangle, or the horizontal fin of symmetry is equipped with in the interior pipe both sides of cross section square-outside and round-inside.
Because heat exchange tube body is graphite making two ends metal joint is housed, graphite is the twice that its thermal conductivity factor of the best nonmetallic materials of thermal conductivity is about steel, and has an excellent corrosion resisting performance, metal joint has solved the connectivity problem with pipe (company) case again, therefore use the heat-exchanger rig of the disclosed graphite longitudinal fin heat exchanger tube assembling of the utility model to have the heat exchange efficiency height, corrosion-resistant, flue gas resistance is little, the section circulation area is big, equipment volume is little, be difficult for ash deposit and slag buildup, advantage such as demand blower fan power trifle is economized electric energy, and is easy to maintenance.
