Description
Technical field
This utility model relates to a kind of heat transfer element.
Background technology
Heat transfer element is the core component of rotary generative air preheater and fume exchanger.In air preheater, the Main Function of heat transfer element is to absorb the used heat that boiler leading portion is discharged, and heats the air carried for boiler combustion and coal dust, and heat transfer element finally forms area and reaches the heat exchange area of tens thousand of to more than ten ten thousand square metres.Heat transfer element is typically formed by sheet metal rolling, sheet metal is milled out bellows-shaped, corrugated surface is divided into enhanced heat exchange district and ash discharge channel slot, these heat transfer element sheets are by ripple production line machine-shaping, load heat transfer element indigo plant subframe, be placed in preheater rotor, when the apparatus is in operation, rotate with rotor, suck heat at high temperature side, return again to release heat during low temperature side, reach the purpose of heat transfer.The operation principle of flue gas heat-exchange unit is similar with air preheat, and the fluid properties only not making to carry out heat exchange is not quite alike, and the hot fluid of quantity of heat given up is the flue gas also not carrying out desulfurization, and the cold fluid of input heat is the flue gas through desulfurization.
In the prior art, heat transfer element for air preheater is generally divided into NF waveform series, CU waveform series, DU waveform series and DN waveform series, these heat transfer elements all by much to steel sheet form, the most also some are had to scribble the heat transfer element of enamel coating, also by much the sheet metal after the application of slip being formed.DU waveform heat transfer element is to be partnered plate by ripple plate always and oblique wave plate, and plate is much superimposed to form a heat transfer element bag, this heat transfer element bag is positioned over air preheater storehouse lattice in, operate with storehouse lattice and can complete the purpose of heat exchange.The straight ripple of straight ripple plate is for ash discharge passage, and between two straight ripples, rolling has oblique ripple, and the ripple on actually straight ripple plate is compound.DU waveform application is commonplace, but it also has obvious shortcoming, this waveform comparison easily stifled ash, that is the ash contained in the flue gas of power plant is easily attaching blocking air duct.
Utility model content
In order to overcome the deficiencies in the prior art, this utility model provides a kind of heat transfer element.
This utility model is achieved through the following technical solutions:
A kind of heat transfer element, but the first straight channel complex wave card that shift to install and second straight channel complex wave card identical including ripple struction, described first straight channel complex wave card and the second straight channel complex wave card are formed by multiple straight corrugated portion and multiple inclined corrugated plate part interleaved, multiple straight corrugated portion and multiple oblique ripple part connection alternate with each other, described straight corrugated portion and inclined corrugated plate part are formed by metal sheet rolling, described straight corrugated portion is sinusoidal pattern, there is crest and trough, described inclined corrugated plate part ripple is skewed sinusoidal pattern, its wave height is less than straight corrugated portion wave height.
Described a kind of heat transfer element, the half straight wave pitch that staggered compared by the ripple of described first straight channel complex wave card and the second straight channel complex wave card.
Described a kind of heat transfer element, the vertical dimension between described straight corrugated portion crest and trough is 8-16mm.
Described a kind of heat transfer element, the spacing between described straight corrugated portion crest and trough is more than 6mm.
Described a kind of heat transfer element, the distance between crest and crest that straight corrugated portion is adjacent is 30-50mm.
Described a kind of heat transfer element, described metal sheet thickness is 0.4-1.0mm.
The beneficial effect that this utility model is reached:
Heat transfer element of the present utility model divides due to more than DU waveform more straight channel ash discharges, thus its blockage resisting Performance comparision is good, heat transfer area DU waveform compared with heat transfer efficiency does not reduce simultaneously, thus its overall performance is compared DU waveform and is significantly improved, due to the every pair of DU waveform that compares, decrease inclined corrugated plate, thus forming process more simplifies, reduce cost and improve efficiency, apply this waveform in low-temperature end simultaneously, at its surface enamel coating can enamel property, operating performance during enamel coating is the most fine, enamel heat transfer element complete after assembling process in burst porcelain probability the least, its rotproofness is verified during the use of GGH and APH of actual steam power plant, durability is the best, heat-transfer effect meets design requirement, prevent dust from attaching functional, dust is prone to purging.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.Following example are only used for clearly illustrating the technical solution of the utility model, and can not limit protection domain of the present utility model with this.
A kind of heat transfer element of the present utility model, but first straight channel complex wave card 1 and the second straight channel complex wave card 2 that shift to install identical including ripple struction, described first straight channel complex wave card 1 and the second straight channel complex wave card 2 are formed by multiple straight corrugated portion 11 and multiple inclined corrugated plate part 12 interleaved, multiple straight corrugated portion 11 and multiple oblique ripple part 12 connection alternate with each other, described straight corrugated portion 11 and inclined corrugated plate part 12 are formed by metal sheet rolling, described straight corrugated portion 11 is sinusoidal pattern, there is crest 111 and trough 112, described inclined corrugated plate part 12 ripple is skewed sinusoidal pattern, its wave height is less than straight corrugated portion wave height.
The half straight wave pitch that staggered compared by the ripple of described first straight channel complex wave card 1 and the second straight channel complex wave card 2.Vertical dimension between described crest 111 and trough 112 is 8-16mm.Spacing between described crest 111 and trough 112 is more than 6mm.Distance between adjacent crest 111 and crest 111 is 30-50mm.Described metal sheet thickness is 0.4-1.0mm.
Some to after heat transfer element superposition, repressurization is assembled in the framework that a weathering steel is welded in, be one group of heat transfer element bag, this element bag be placed in the storehouse lattice of air preheater be with storehouse lattice operating can complete heat transfer purpose.Specifically can be for the actual requirement of Algorithm Stability of Gas Turbine Performance, according to the total circulation of its flue gas, treat preheated air flow, the cold end of flue gas and hot-side temperature requires, the cold end of preheated air and hot-side temperature require, calculate each design parameter meeting its heat transfer element required.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; on the premise of without departing from this utility model know-why; can also make some improvement and deformation, these improve and deformation also should be regarded as protection domain of the present utility model.
