The utility model content
The purpose of this utility model is to provide a kind of flat air preheater, heat transfer efficiency height, resistance reduce, sealing reliably, effectively improves service life of equipment, existing flat air preheater structure, complex manufacturing technology have been solved, the difficult problem that manufacture difficulty is big.
The technical solution of the utility model is as follows: a kind of flat air preheater, comprise the heat transfer plate bundle, and the heat transfer plate pipe of described heat transfer plate bundle is by two heat transferring plates and place the full welding of supporting component between these two heat transferring plates to constitute; Described supporting component is welded by sealing strip, support bar and the connector that connects described sealing strip and support bar.
The sealing strip of described supporting component is consistent with the flow direction of the interior medium of heat transfer plate pipe at the length direction of support bar and its place, and the length direction of described connector is vertical with the flow direction of the interior medium of heat transfer plate pipe at its place.
Described sealing strip is steel bar or rod iron, and support bar is steel bar or rod iron or corrugated sheet, and connector is steel bar or rod iron or corrugated sheet.
Described heat transferring plate is the metal plate sheet.
Described heat transfer plate bundle is folded by a plurality of heat transfer plate pipes that to fall to forming plate folded, and the folded upper and lower end face of this plate arranges pressure strip respectively, between the pressure strip of the folded upper and lower end face of described plate the pressure strip lacing wire is installed; Folded four jiaos of described plate are fixed with side plate; And described pressure strip and side plate are fixing in the enclosure.
The utility model is simple in structure, easily manufactured, heat transfer efficiency is high, pressure drop is low, can effectively improve service life of equipment.

The specific embodiment
Below in conjunction with accompanying drawing the utility model and beneficial effect thereof are further described.
With reference to Fig. 1, a kind of flat air preheater comprises gas approach runner 1, gas approach flange 2, heat transfer plate bundle 3, air intlet flange 4, air intlet runner 6, exhanst gas outlet flange 7, exhanst gas outlet runner 8, air outlet slit flange 9, air outlet slit runner 10 and external shell 5 constitute, and described flue gas import and export runner 1,8 and air import and export runner 6,10 be interlaced arrangement around shell 5.Heat transfer plate bundle 3 is installed in the shell 5.Cigarette, air are connected into and out of runner and outside cigarette, air duct welding or by flange.
With reference to Fig. 3,4,5, the heat transfer plate pipe 14 of described heat transfer plate bundle 3 is by two heat transferring plates 16 and place the supporting component 17 full welding between these two heat transferring plates 16 to constitute; Described supporting component 17 is welded by sealing strip 20, support bar 21 and the connector 19 that connects described sealing strip 20 and support bar 21.This supporting component 17 is overall structure, and its sealing strip 20 does not weld with heat transferring plate 16 with heat transferring plate 16 welding, support bar 21 and connector 19, makes the simple in structure of heat transfer plate pipe 14, and is easily manufactured.Wherein sealing strip 20 namely has sealing function that the effect that the cold and hot fluid runner is separated is arranged again.
