Abstract
The invention discloses a heat transfer tube which is used for an air preheater. The heat transfer tube comprises two same finned plates, the finned plates comprise plate bodies and multiple fins, the shape of the cross section of the vertical direction of each plate body is shaped like a Chinese character 'men', the fins are connected on the surface of the plate bodies, opening ends of the two finned plates are oppositely jointed in an abutting mode to form a pipeline, the fins are arranged on two sides of a heat transfer plate, and heat transfer is strengthened. Directions of the two side fins are mutually perpendicular and are consistent with the flow direction of the medium in a corresponding channel, resistance is reduced, and dust is not easily accumulated. Simultaneously, materials of the finned plate obtained by a casting method are casting heat-resisting alloy steel or aluminium alloy, and domestic blank is filled. Compared with traditional similar products, the heat transfer tube has great advantages in terms of thermostability performance, heat transfer efficiency and uneasy deposition.
Description
Technical field
The technical program belongs to heat exchange device technical field, specifically a kind of high temperature resistant heat-transfer pipe for air preheater.
Background technology
The operation principle of air preheater is, hot flue gas and cold air are carried out heat exchange, and hot flue-gas temperature reduces, and reclaims heat, reaches discharging.The cold air temperature raises, and obtains heat, as combustion-supporting, and fuel saving, this just requires heat exchanger components to have good heat transfer effect.Temperature due to hot flue gas is very high in addition, the highest can be greater than 1000 ℃, in addition, hot flue gas itself has very strong corrosivity, the performance of heat exchanging device under hot conditions has high requirements like this.
Summary of the invention
For the physico/chemical properties of the hot flue gas of being satisfied with air preheater and the high request of heat exchange property heat exchanger, the technical program proposes a kind of new heat-transfer pipe, and concrete technical scheme is as follows:
A kind of heat-transfer pipe for air preheater comprises two identical fin plates; Described fin plate comprises plate body and a plurality of fin, and the shape in the vertical direction cross section of plate body is " door " font, and each fin is connected to the surface of plate body; The openend of two fin plates docks the formation pipeline in opposite directions.
Described fin plane is vertical with the plate body plane.Described fin is connected to inner surface and the outer surface of plate body.The fin plane of inner surface that is connected to plate body is consistent with the length direction of pipeline.The fin plane of outer surface that is connected to plate body is vertical with the length direction of pipeline.
The two side of " door " font openend of described plate body all is provided with the bending edges outside pipeline; The bending edges of the correspondence of two fin plates is closely connected.Be provided with sealing gasket between the bending edges that the correspondence of two fin plates connects, pass through bolted between two bending edges and sealing gasket.
The material of described fin plate is chrome-nickel steel or aluminium alloy.Described fin plate is the overall structure of casting.
The technical program heat exchanger plates both sides are all with fin, augmentation of heat transfer.The direction of both sides fin is mutually vertical, and is consistent with media flow direction in respective channel, reduces resistance, is difficult for dust stratification.Adopting simultaneously the fin plate material that casting method obtains is casting heat-resistant steel alloy (heat resisting temperature can reach 1100 degree) or aluminium alloy (material is Birmasil, has excellent decay resistance and lightweight), fills the domestic gaps.Compare traditional like product, from resistance to elevated temperatures, heat exchange efficiency be difficult for all having very large advantage on dust stratification.
