1 is pincushion plate, and the double-layer structure of heat exchanger plates 1 includes upper heat exchange plate 14, lower heat exchange plate 15, upper heat exchange plate 14, lower heat exchange
Plate 15 is the thin plate of sheet, with multiple being formed by welding and mutual between upper heat exchange plate 14, lower heat exchange plate 15
Independent contact portion 13.Each contact portion 13 be laser spot welding formation, spot welding make upper layer and lower layer plate spot welding region contact melt
It closes, the periphery progress soldering of upper heat exchange plate 14, lower heat exchange plate 15, and stays an inflatable mouth.Due to upper heat exchange plate 14,
There is gap between lower heat exchange plate 15, by injecting high pressure gas at inflatable mouth, so that expansion becomes in upper and lower heat exchange plate
Shape, and then form combustion air chamber 16.Then combustion air inlet 11 and combustion air outlet 12 are reprocessed out.This structure
Heat exchanger plates, so that internal heat channel is compact narrow, faster, and heat exchanger plates are stacked flow velocity, exhaust steam passage and combustion air
Channel it is successively interleaved, can more make full use of exhaust gas heat carry out heat exchange, improve heat transfer effect.
Inner hull 3 is from top to bottom successively arranged the exhaust gas entrance 31 of a column and the combustion air inlet 22 of a column, Shell Plate 2
It is equipped with the exhaust vent 21 of a column and the combustion air exhaust outlet 32 of a column.Each combustion air inlet 22 respectively with belong to it is same
The corresponding connection of combustion air inlet 11 of each heat exchanger plates 1 of one heat exchange unit, each combustion air exhaust outlet 32 respectively with belong to
The corresponding connection in combustion air outlet 12 of each heat exchanger plates 1 of same heat exchange unit.Belong to the combustion air of the same heat exchange unit
The quantity of entrance 22 is identical as 1 quantity of heat exchanger plates, and combustion air exhaust outlet 32 is identical as 22 quantity of combustion air inlet.This implementation
In example, a heat exchange unit has 26 heat exchanger plates 1.The combustion air inlet 11 of heat exchanger plates is welded and fixed with inner hull 3, is changed
The combustion air outlet 12 of hot plate 1 is welded and fixed with Shell Plate 2, only combustion air is allowed to be flowed into from combustion air inlet
Corresponding combustion air inlet 11, and enter combustion air chamber 16, then 12 are exported from combustion air outlet 12, with combustion air
Corresponding combustion air exhaust outlet 32 is discharged, and combustion air cannot be entered in the space between neighbouring heat exchanger plates 1
, it prevents from mixing with exhaust gas.
There is spacing between the neighbouring heat exchanger plates 1, be arranged in parallel, to form exhaust gas chamber, the big small capital of the spacing is real
It applies and uses 15mm in example, in other embodiments, the value in the range of 10~30mm can be used.Each exhaust gas entrance 31 with belong to it is same
The corresponding connection of exhaust gas chamber of heat exchange unit, the connection corresponding with the exhaust gas chamber of same heat exchange unit is belonged to of each exhaust vent 21.
Belong to quantity one fewer than amount of heat exchanger plates of the exhaust gas entrance 31 of the same heat exchange unit, namely there are 25 exhaust gas entrances 31,
Exhaust vent 21 is identical as 31 quantity of exhaust gas entrance.That is, the exhaust gas for the high temperature that turbine generates is flowed by each exhaust gas entrance 31
It is discharged to exhaust gas chamber, then by exhaust vent 21.
Inner hull 3, Shell Plate 2 are arc-shaped plate.Exhaust gas entrance 31, exhaust vent 21 are respectively along inner hull 3, outer
The long hole of coverboard 2 being circumferentially arranged.
The inner wall welding of inner hull 3 is equipped with combustion air air inlet pipe 4, each combustion in combustion air air inlet pipe 4 and inner hull 3
Air intake 22 is burnt to be connected to；The outer wall welding of Shell Plate 2 is equipped with combustion air exhaust pipe 5, combustion air exhaust pipe 5 and Shell Plate
Each combustion air exhaust outlet 32 connection on 2.Combustion air air inlet pipe 4, combustion air exhaust pipe 5 are in semi-circle tubular.Burning
The length direction of air intake duct 4 is along the axial direction of heat exchanger, and its length and the length in the axial direction of inner hull 3 are almost the same,
At least guarantee that 4 upper end of combustion air air inlet pipe is aligned with 3 upper end of inner hull.The axis of combustion air exhaust pipe 5 length and Shell Plate 2
Almost the same to length, at least guarantee 5 lower end of combustion air exhaust pipe is aligned with 2 lower end of Shell Plate.Combustion air is empty by burning
4 top of gas air inlet pipe enters, and flows into heat exchanger plates 1, after heat exchange, then by the discharge downwards of combustion air exhaust pipe 5.
It is equipped with partition 6 between adjacent heat exchange unit, so that the exhaust gas chamber on adjacent heat exchange unit is kept apart, forms four
Independent heat exchange unit.Partition 6 be it is vertically arranged, 6 two sides of partition are fixed with each heat exchanger plates 1 of two sides respectively.Setting every
Plate prevents exhaust gas from forming short circuit, influences heat transfer effect.
When heat exchanger works, the exhaust gas of high temperature enters from the exhaust gas entrance 31 on inner hull 3, flows through neighbouring heat exchange
Exhaust steam passage between plate, and be discharged from exhaust vent 21；Combustion air is from the combustion air air inlet pipe 4 being arranged on inner hull 3
Into flowing through the combustion air chamber 16 of heat exchanger plates, and be discharged from combustion air exhaust pipe 5.The channel that the exhaust gas of high temperature is flowed through
It is different channel with the channel that combustion air is flowed through, two kinds of channels are mutually indepedent but adjacent, to realize the mesh of heat exchange
's.Heat exchanger can significantly improve the efficiency of turbine engine system after waste-gas heat is transmitted to combustion air, and can have
The reduction system fuel of effect consumes.The exhaust temperature of exhaust gas is also reduced simultaneously, takes into account energy-saving and environment-friendly effect.
