Abstract
The utility model relates to a novel fin tube plate heat transfer pipe which comprises two same fin plates. Each fin plate comprises a plate body and a plurality of fins; the section of each plate body in the vertical direction is of an inverted U shape; each fin is connected onto the surface of the corresponding plate body; open ends of the two fin plates are oppositely abutted to form a pipeline; the fins are vertical to the plane of the plate bodies; each fin is respectively connected to the inner surface and the outer surface of the corresponding plate body; for the fins connected to the inner surfaces of the corresponding plate bodies, the length direction of the fins is consistent with that of the pipeline, the fins are of a flat and straight shape and an air duct formed by arranging the fins is of a straight line shape; and for the fins connected to the outer surfaces of the corresponding plate bodies, the length direction of the fins is vertical to that of the pipeline, one surfaces of the fins are flat and straight and the other surfaces of the fins are of an arc shape and the air duct formed by arranging the fins is of an S shape. By the adoption of the technical scheme, the fluid state of a heat transfer medium is more excellent and a better turbulent flow effect is generated.
Description
Technical field
The present technique scheme belongs to heat exchange device technical field, specifically is a kind of high temperature resistant novel finned tube plate heat-transfer pipe that is used for air preheater.
Background technology
The operation principle of air preheater is, carries out heat exchange to hot flue gas and cold air, 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 exchange effect.In addition because the temperature of hot flue gas is very high, 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 of the hot flue gas of being satisfied with air preheater and the high request of heat exchange property heat exchanging device, the present technique scheme proposes a kind of new heat-transfer pipe, and concrete technical scheme is following:
A kind of novel finned tube plate heat-transfer pipe comprises two identical fin plates; Said 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 the surface of plate body; The openend of two fin plates docks the formation pipeline in opposite directions; Said fin is vertical with the plate body plane, and each fin is connected to the inner surface and the outer surface of plate body;
Fin for the inner surface that is connected plate body:
The length direction of fin is consistent with the length direction of pipeline; Fin is a flat shape, and it is rectilinear form that each fin is arranged the air channel that constitutes;
Fin for the outer surface that is connected plate body:
The length direction of fin is vertical with the length direction of pipeline; The one side of fin is straight, and another side is an arc, and it is the serpentine shape that each fin is arranged the air channel that constitutes.
The cross section of the length direction of the fin of the said outer surface that is connected plate body is trapezoidal.
The two side of " door " font openend of said plate body all is provided with the bending edges outside pipeline; The bending edges of the correspondence of two fin plates is closely connected.Between the bending edges that the correspondence of two fin plates connects, be provided with sealing gasket, pass through bolted between two bending edges and the sealing gasket.
The material of said fin plate is cast iron or chrome-nickel steel or Birmasil, preferably low-alloy spheroidal graphite cast-iron.
Said fin plate is the overall structure of casting.
Big top is little at the bottom of being connected the fin of outer surface of plate body, and the base thickness top is thin, and intensity is high, the requirement of the pattern draft when satisfying casting.This structural strength will be much better than the fin of flat construction, and the effective heat transfer sheet area increasing of fin, fin weight saving, and the fin end face is thinner, more is difficult for dust stratification, is that of structural design improves greatly.
The arc surface of fin that constitutes the outer surface that is connected plate body in S type air channel arrangements that misplace in opposite directions laterally is the equidirectional arrangement, and spacing is equal.
Use the present technique scheme, the fluid state of heat transferring medium (flue gas or air) is better, produces flow-disturbing effect preferably.Fluid is constantly shunting and interflow in staggered array of fins, and flows along camber line all the time, makes the stroke of medium in array of fins longer, and the time of staying is longer, has improved heat exchange efficiency.This can only need fin heat exchange pipe still less under the condition of identical heat, equipment is lighter, and volume is littler, invests more economical.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment present technique scheme is further specified as follows:
A kind of novel finned tube plate heat-transfer pipe comprises two identical fin plates; Said 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 the surface of plate body; The openend of two fin plates docks the formation pipeline in opposite directions; Said fin is vertical with the plate body plane, and each fin is connected to the inner surface and the outer surface of plate body;
Fin for the inner surface that is connected plate body:
The length direction of fin is consistent with the length direction of pipeline; Fin is a flat shape, and it is rectilinear form that each fin is arranged the air channel that constitutes;
Fin for the outer surface that is connected plate body:
The length direction of fin is vertical with the length direction of pipeline; The one side of fin is straight, and another side is an arc, and it is the serpentine shape that each fin is arranged the air channel that constitutes.
The cross section of the length direction of the fin of the said outer surface that is connected plate body is trapezoidal.
The two side of " door " font openend of said plate body all is provided with the bending edges outside pipeline; The bending edges of the correspondence of two fin plates is closely connected.Between the bending edges that the correspondence of two fin plates connects, be provided with sealing gasket, pass through bolted between two bending edges and the sealing gasket.
The material of said fin plate is cast iron or chrome-nickel steel or Birmasil, preferably low-alloy spheroidal graphite cast-iron.Said fin plate is the overall structure of casting.
In this example, be connected the fin of outer surface of plate body at the bottom of big top little, the base thickness top is thin, intensity is high, the requirement of the pattern draft when satisfying casting.This structural strength will be much better than the fin of flat construction, and the effective heat transfer sheet area increasing of fin, fin weight saving, and the fin end face is thinner, more is difficult for dust stratification, is that of structural design improves greatly.The arc surface of fin that constitutes the outer surface that is connected plate body in S type air channel arrangements that misplace in opposite directions laterally is the equidirectional arrangement, and spacing is equal.
