Abstract
The invention relates to an ellipsoidal corrugated heat transmission sheet structure. Corrugation of a heat transmission sheet corrugated section consists of semi-ellipsoidal curved surfaces arrayed in a matrix manner; long axes of the semi-ellipsoidal curved surfaces are in the same direction as the long side of a heat transmission sheet; and middle axes of the semi-ellipsoidal curved surfaces are in the same direction as the broad side of the heat transmission sheet. The structure has the following advantages that: 1) the corrugation of the heat transmission sheet consists of the semi-ellipsoidal curved surfaces, and is provided with a larger heat transmission surface, so that a coefficient of heat transmission is increased; 2) the semi-ellipsoidal curved corrugation has higher strength and rigidity according to a shell theory, and does not deform easily; and 3) the structure is simple, is formed by one-time stamping; and the production cost is lowered. With the adoption of the structure, a heat transmission area is increased; the strength and the rigidity are improved; the flow channel resistance is reduced simultaneously; the new balance between the reduced flow resistance and a good heat transmission effect is achieved; and a significant progress is obtained.
Description
Technical field
The present invention relates to the general purpose accessory of a kind of heat exchange and heat-transfer equipment, more specifically to a kind of spheroid shape ripple heat transfer plate sheet structure for the air/gas preheater.
Background technology
Full welding plate formula air/gas preheater is applied to the blast furnace ironmaking industry, can improve significantly Blast Temperature.Corrugated cardboard sheet directly affects the heat-transfer effect of preheater as its heat transfer element, because the hot-blast stove fume waste heat supply temperature is high, exhaust gas volumn is large, the characteristics such as little fall in required pressure, the heat transfer element of traditional form is not suitable with under this kind operating mode and works, and heat-transfer effect is poor, suddenly waits to improve.
Summary of the invention
The objective of the invention is to provide for the prior art weak point spheroid shape ripple heat transfer plate sheet structure that is used for the air/gas preheater that a kind of heat transfer efficiency is high, less scaling, be convenient to clean, be easy to make.
The objective of the invention is to realize by following measures: a kind of spheroid shape ripple heat transfer plate sheet structure for the air/gas preheater, its special character is: the ripple of described heat transferring plate corrugated regions forms by being the semielliptical curved surface that matrix arranges; the major axis of half Elliptical ball curved surface and heat transfer length of a film limit in the same way, the axis of half Elliptical ball curved surface and heat transfer sheet broadside are in the same way.
Described matrix is arranged as on odd number row's the even column position as being the semielliptical curved surface of indent on the odd column position of the semielliptical curved surface of evagination, even rows.
Described matrix is arranged as on odd number row's the even column position as being the semielliptical curved surface of evagination on the odd column position of the semielliptical curved surface of indent, even rows.
Described corrugated regions is provided with some spacing columns, and spacing column is semiellipsoid.
Compared with prior art, the spheroid shape ripple heat transfer plate sheet structure that is used for the air/gas preheater of the present invention's proposition has following advantage: 1) the heat transferring plate ripple has larger heating surface by the ripple that the semielliptical curved surface forms, and has improved heat transfer coefficient; 2) ripple of semielliptical curved surface has higher strength and stiffness according to theory of thin shell, and is not yielding; 3) simple in structure, one time punching molded, reduced production cost.The present invention has also reduced flow passage resistance force of waterproof when increasing heat transfer area, improving intensity and rigidity, reached new balance between the heat-transfer effect that not only reduces flow resistance but also obtain, and has obtained significant progress.
Description of drawings:
Fig. 1 is ripple heat transfer plate sheet structural representation of the present invention.
Fig. 2 is Fig. 1 A-A profile.
Fig. 3 is Fig. 1 B-B profile.
The specific embodiment:
Below in conjunction with accompanying drawing the specific embodiment is elaborated:
Fig. 1～Fig. 3 is ripple heat transfer plate sheet structural representation of the present invention.Among the figure, a kind of spheroid shape ripple heat transfer plate sheet structure for the air/gas preheater, the ripple of described heat transferring plate 1 corrugated regions forms by being the semielliptical curved surface 2 that matrix arranges, the major axis of half Elliptical ball curved surface and heat transfer length of a film limit in the same way, the axis of half Elliptical ball curved surface and heat transfer sheet broadside are in the same way.Described matrix arrange can be on odd number row's the even column position for being the semielliptical curved surface of indent on the odd column position of the semielliptical curved surface of evagination, even rows, also can be for being the semielliptical curved surface of evagination on the odd column position of the semielliptical curved surface of indent, even rows on the even column position of arranging for odd number.
The present invention further takes following measure: described corrugated regions is provided with some spacing columns 3, and spacing column is semiellipsoid.Spacing column the bearing capacity that can increase heat transferring plate is set.
Make ripple heat transfer plate sheet according to the present invention, can be used for full welding plate formula air/gas preheater.The semielliptical shape of pressing the matrix arrangement is protruding, concave curved surface is reducing flow passage resistance force of waterproof, in the time of the increase heat transfer area, has avoided the reduction of plate bearing capacity.By the plate pipe that this heat transferring plate forms, form a kind of uniform passage, the flow channel cross-section of fluid is long-pending to remain unchanged, simultaneously fluid in runner by the time can between ripple, constantly change flow direction, can reduce flow resistance, augmentation of heat transfer, be difficult for dust adhesion.By the plate bundle that this heat transferring plate is welded into, the both sides flow passage structure is identical, and medium is alternating expression and flows in both sides, and heat-transfer effect is good.
Below be described in conjunction with the embodiments, above-described embodiment is not construed as limiting the invention, as long as employing is equal to the technical scheme that the form of replacement or equivalent transformation obtains, all drops within protection scope of the present invention.
