Abstract
The invention discloses a kind of oblique wave wave type corrugated plating, including plate body one and plate body two, it is characterised in that the plate body one is provided with the ripple one for tilting upward；Plate body two is provided with the ripple two for tilting upward.The present invention adopts undaform corrugated plating, increases with the contact area of fluid than the corrugated plating of traditional line type, can reduce part heat-transfer surface while heat exchange property is met, reach saving material, reduces the purpose of air preheater cost；Additionally, enhanced heat transfer component heat exchange efficiency of the present invention, reduces the exit fluid temperature of air preheater, reaches cost efficiency, the purpose of energy-saving and emission-reduction.
Description
Technical field
The present invention relates to a kind of for air preheater and the heat transfer element of flue gas heater, and in particular to a kind of oblique wave wave
Type corrugated plating, belongs to technical field of heat exchangers.
Background technology
Rotary type heat exchanger is the core component of rotary regenerative air preheater and flue gas heater.Its Main Function is to absorb
Boiler leading portion discharges used heat, carrys out heating boiler burning and coal dust conveys air, or reheat the flue gas after desulphurization system cooling.Its
Heat exchange element reaches tens thousand of to hundreds thousand of square metres of steel sheet for surface area, and steel sheet surface rolling goes out the thin of bellows-shaped
The plate thin plate corrugated surface absorbs the heat of flue gas.These heat transfer element pieces by streamline machine-shaping is rolled, according to installing frame
Frame size loads in heat transfer element bag, is placed in preheater rotor, when equipment runs, rotates with rotor, in fume side (high temperature
Side) suction heat, heat is discharged when air side is gone to, complete the purpose of heat transfer.
In the prior art, the heat transfer element for air preheater is generally divided into NF series, CU series, DU series and DN
Series, these heat transfer elements are all made up of much paired steel sheet.In these series, all of group of Chengdu is by
Lower two panels partners, upper piece we be referred to as location-plate, bottom sheet is referred to as corrugated plating, for example：DU series heat transfer elements have DU waveforms
With DU3 waveforms, structure is identical therebetween, and which is distinguished and is the highly different of ripple.As shown in Figure 1-2, which is by two pieces of folds
Corrugated plating composition, corrugated plating 1 with tiltedly straight ripple 1 and smooth straight channel groove 4, only oblique straight ripple two on corrugated plating 2
5.Tiltedly straight ripple 1 is consistent with oblique straight 25 direction of ripple.Corrugated plating 1 is through roll forming twice, is first rolled with a pair of rolling rolls
Tiltedly straight ripple 1 is made, and straight channel groove 4, i.e. ash discharge channel slot is rolled out to rolling roll with another again then.Due to these heat transfer units
The oblique ripple of part is all skew lines type, and when heat-exchange fluid passes through, the few resistance of contact surface is little, therefore can have lost a part of heat
Exchange the heat of fluid.
Content of the invention
The technical problem to be solved is to provide a kind of corrugated plating than existing skew lines type and more can inhale
Receive the heat transfer element of flue gas heat.
In order to solve the above problems, the technical solution adopted in the present invention there is provided a kind of oblique wave wave type corrugated plating, bag
Rubbing board body one and plate body two, it is characterised in that the plate body one is provided with the ripple one for tilting upward；Plate body two is provided with inclination
Ripple two upwards.
Preferably, the ripple one, the angle of inclination of ripple two are that relative plate face inclines 50～65 °, and ripple is wave
Type is upwards；Ripple one, ripple two are a cycle at interval of 100-200mm, and fluctuate ± 2～8mm up and down.
Preferably, the ripple one, ripple two are circular arc.
Preferably, one point of the ripple on the plate body one is uniformly multiple corrugated regions, sets between two neighboring corrugated regions
There is straight channel groove.
Compared with prior art, the beneficial effects of the present invention is：
1st, undaform corrugated plating is adopted, is increased with the contact area of fluid than the corrugated plating of traditional line type, is changed in satisfaction
Part heat-transfer surface can be reduced while hot property, saving material is reached, reduce the purpose of air preheater cost；
2nd, enhanced heat transfer component heat exchange efficiency, reduces the exit fluid temperature of air preheater, reaches cost efficiency, energy-conservation
The purpose of reduction of discharging；
3rd, the technology of traditional manufacture skew lines type corrugated plating component structure, due to falling for manufacturing equipment and manufacturing technology
Afterwards, be difficult to manufacturing this oblique wave wave type corrugated plating component structure, now with the progress of science and technology, equipment manufacturing equipment and
The lifting in big strides of technology, numerical control machining center, three-shaft linkage, four-axle linked etc. sophisticated equipment and technology cause to manufacture this
Plant complicated oblique wave wave type corrugated plating component structure to be achieved.

Specific embodiment
For becoming apparent the present invention, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Embodiment
As shown in figure 3, a kind of heat transmission element structure for air preheater oblique wave wave type ripple provided for the present invention
The structural representation of plate, including plate body 1 and plate body 27, after two pieces of corrugated plating assemblings, its structural diagrams is intended to as shown in Figure 4.
Plate body 1 is provided with ripple 1, and ripple 1 is divided into multiple uniform corrugated regions, is provided with straight channel between two neighboring corrugated regions
Groove 9.Plate body 27 is provided with ripple 2 10.Wherein, ripple 1 and ripple 2 10 identical set on direction.Straight channel groove 9
Longitudinal section is the curve with a crest and a trough.
On ripple 1 and ripple 2 10, shallow undaform ripple is distributed with, shallow waveform ripple is with 60 ° of long diagonals as X
Axle amplitude is the sine wave that the 7mm cycles are 200.Its section configuration is as shown in figure 5, in isosceles triangle bottom roundings α be
R2.5mm, top fillet β are R1.5mm, and its depth h is 8mm.Base l is 15mm.
The present invention by smooth tiltedly shallow undaform corrugated design into along at angle gamma with base be 60 ° long diagonal be the ripple
The wide centrage of stricture of vagina, upper and lower ± 7mm fluctuations on the basis of centrage, adjacent 200mm is that a cycle T is distributed ripple one 8, ripple
2 10, certain resistance is produced when heat-exchange fluid is by wave channel, the speed for affecting heat-exchange fluid to pass through.Oblique with existing
Straight type ripple 3,5 is compared, and shallow waveform ripple 10 considerably increases the contact area of corrugated plating and heat-exchange fluid, can be with more
Ground absorbs the heat of heat-exchange fluid, so as to improve heat transfer element efficiency, reduces portions under heat face, reaches the mesh of material-saving
's.
