Abstract
The utility model relates to a corrugated plate type air pre-heater. The corrugated plate type air pre-heater comprises corrugated plates (1), left and right sides of which are provided with downwardly-turning edges formed by stamping. Front and rear sides of the corrugated plates are provided with upwarpping edges formed by stamping. Corrugated bodies (2) formed by stamping are arranged on bodies of the corrugated plates (1) which are arrayed in a laminated mode. A corrugated plate combination body (4) provided with a sealing channel is formed in such a manner that the two adjacent corrugated plates (1) are oppositely arranged and two groups of edges on the left and the right or at the front and the back are welded. Four corners of each corrugated plate (1) are secured to a framework (3). The corrugated plate type air pre-heater has following beneficial effects: heat transfer of heat transferring mediums between smoke and air in an orthogonal flow direction is carried out in the sealing channels of the two adjacent corrugated plate combination bodies; the corrugated bodies, formed by stamping and arranged on the bodies of the corrugated plates, are used for supporting between the two adjacent corrugated plates; and by changing supporting positions of the corrugated bodies in a low temperature area of a heat transferring plate and changing flow patterns of the mediums to increase the temperature of a plate wall, dew point corrosion due to low temperature is effectively delayed and prevented.
Description
Technical field
The utility model relates to a kind of air preheater, for the recycling of oil refining industry fume afterheat.Belong to petroleum industry technical field.
Background technology
What the air preheater of existing oil refining industry adopted is flat-plate air air preheater, and because this preheater does not arrange strengthening medium heat-transfer, its heat transfer efficiency is lower; Inner support part is set between plate, makes complex structure, cost of manufacture is high; Plate cannot absorb welding residual stress, worst hot case thermal stress and cause equipment deformation failure, makes easily to occur low-temperature space dew point corrosion situation in structure simultaneously, and service life is low.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of corrugated plate dst air preheater is provided.
The purpose of this utility model is achieved in that
A kind of corrugated plate dst air preheater, comprise corrugated plating, be characterized in: the right and left of described corrugated plating is flange edge under punch forming, both sides, front and back are the stamping forming edge that upwarps, on the body of corrugated plating, there is punch forming corrugated body, the stacked arrangement of described multiple corrugated plating, adjacent two corrugated platings are staggered relatively and form a corrugated plating assembly that has seal channel by left and right or the edge welding of two groups of front and back, MEDIA FLOW in described adjacent two seal channels is to orthogonal, and four bights of described each corrugated plating are fixed on framework.
A kind of corrugated plate dst air preheater of the utility model, its corrugated body is shaped as circle, arc or trapezoidal.。
Compared with prior art, the beneficial effects of the utility model are:
A kind of corrugated plate dst air preheater of the utility model, heat transferring medium flue gas and air carry out the orthogonal heat exchange that flows at the seal channel of adjacent two corrugated plating assemblys, between adjacent two corrugated platings, support by stamping forming corrugated body on corrugated plating body, simple in structure, cost of manufacture is low; By changing heat exchanger plates low-temperature space corrugated body Support Position, change medium flow pattern and improve wooden partition temperature, delay and effectively prevent low-temperature dew point corrosion, therefore high life; The forms such as the series and parallel connections by multiple preheaters combine to increase heat transfer area, thereby improve heat transfer effect.

Detailed description of the invention
Referring to Fig. 1-2, the utility model relates to a kind of corrugated plate dst air preheater, it comprises corrugated plating 1, the right and left of described corrugated plating 1 is flange edge under punch forming, both sides, front and back are the stamping forming edge that upwarps, on the body of corrugated plating 1, there is punch forming corrugated body 2, described corrugated body 2 be shaped as circle, arc or trapezoidal, described multiple corrugated plating 1 stacked arrangement and adjacent two corrugated platings 1 are staggered relatively and form a corrugated plating assembly 4 that has seal channel by left and right or the edge welding of two groups of front and back, four bights of described each corrugated plating 1 are fixed on framework 3.
The utility model can combine to increase heat transfer area by forms such as the series and parallel connections of multiple preheaters, thereby improves heat transfer effect.
Operation principle: adjacent two corrugated platings 1 are staggered relatively and form a corrugated plating assembly 4 that has seal channel by left and right or the edge welding of two groups of front and back, MEDIA FLOW in described adjacent two seal channels is to orthogonal, heat transferring medium flue gas and air carry out the orthogonal heat exchange that flows at the seal channel of adjacent two corrugated plating assemblys 4, between adjacent two corrugated platings 1, support by stamping forming corrugated body 2 on corrugated plating 1 body.
Claims (2)
