Abstract
The invention discloses a dot type wide flow passage fully-welded heat exchange plate, which belongs to components of heat exchange equipment indirectly contacted with heat exchange media. The structure of the heat exchange plate is as follows: protrusions in a flat topping semisphere shape and pits in a flat low semisphere shape are distributed in rectangular arrays on rectangular plate sheets bytaking the connecting line of the midpoints of short edges of as a symmetry axis, central connection lines of lines or rows of the protrusions and central connecting lines of lines or rows of the pits are arranged at intervals, and the brims of the short edges and the brims of long edges are respectively at the same level with the top surfaces of the protrusions and the bottom surfaces of the pits. A heat exchanger assembled by the heat exchange plate has a wide flow passage with visible two ends of a medium inlet and a medium outlet, which is advantageous to air circulation, resistance reduction and uneasy dust accumulation; with a structure of round protrusions or the pits, the supporting strength among the plate sheets is strengthened, and the effective heat exchanging area of the plate sheets is increased simultaneously, thus high speed turbulent flow can be formed when the flow rate is low, the heat exchange efficiency is high, and simultaneously the generated turbulent flow cangenerate self sweeping function to the accumulated dust.
Description
Technical field
The invention belongs to the not direct parts of heat-exchange apparatus of contact of heat exchange medium, especially for the parts of all welded type heat-exchange apparatus of the fixed head of two kinds of gas exchange medias or lamination channel components.
Background technology
Welded plate heat exchanger is special in thermoelectric, nuclear power, chemical industry, oil refining, some high temperature of industries such as smelting, the needs of high pressure operating mode and the high-efficiency heat exchanger equipment that designs, it has drawn the plurality of advantages of similar products at home and abroad, both kept plate type heat exchanger heat transfer efficiency height, advantages such as volume is little, has shell-and-tube heat exchanger pressure-bearing height again, the characteristics that heatproof is high, in order to guarantee can not go here and there between the medium liquid and the phenomenon generation that leaks outside, special corrugated cardboard sheet periphery has formed the variation of its product structure form by welding, is the ideal equipment that substitutes shell-and-tube heat exchanger in some special heat exchange process.But now all welded type plate of using can only be used for heat exchange places such as the pure solution-air of liquid-liquid, vapour-liquid and low discharge, gas-gas because runner is narrow, complex structure, resistance are big, easily dust stratification and shortcoming such as easy cleaning not.But the majority of gas of real operating mode have flow big, contain dust, pressure is low or be negative pressure, if with narrow runner, baroque corrugated plating or the oval pancake plate that is in tilted layout, its resistance is very big, and easy to clean not behind the dust stratification, has a strong impact on the equipment use.
Summary of the invention
The purpose of this invention is to provide a kind of circle dot mode width flow passage fully-soldering heat exchange plate with characteristics such as big flow, low-pressure, little, the unsuitable dust stratification of resistance, easy to clean.Another object of the present invention provides the preparation method of this plate, and the novel all welded type heat exchanger that uses this plate assembling.
Technical scheme of the present invention is, a kind of circle dot mode width flow passage fully-soldering heat exchange plate, it is characterized in that: be the pit that the rectangular array distribution of symmetry axis the low hemisphere face shape of projection peace of flat-top hemisphere face shape with minor face mid point line on the plate of rectangle, the line of centres of the column or row of the line of centres and the pit of the column or row of projection is spaced, and the minor face edge, to grow the edge, limit concordant with the pit bottom surface with protruding end face respectively.
The projection or the pit of described flat-top hemisphere face shape, its top are that diameter is 2～10 millimeters horizontal disks, are that radius is 5～40 millimeters a part spherical shell below the disk, and the chamfer radius of spherical shell and plate is 5～40 millimeters, and it is 10～80 millimeters that plate is pressed bore dia.
The pit bottom of the convex top of described flat-top hemisphere face shape or flat low hemisphere face shape and the distance of plate are 5～30 millimeters.
The projection or the pit of described flat-top hemisphere face shape, the distance of center circle between neighboring projection are horizontal 80～200 millimeters, and vertical 80～200 millimeters, the distance of center circle between adjacent pit also together.
The preparation method of circle dot mode width flow passage fully-soldering heat exchange plate is: described heat exchanger plates adopts use hydraulic press compactings such as corrosion resistant plate, nickel plate, titanium plate, Hastelloy, titanium palldium alloy to form.
The heat exchanger that uses aforesaid circle dot mode width flow passage fully-soldering heat exchange plate to make, its structure is: at least three positive and negative alternate combinations of circle dot mode width flow passage fully-soldering heat exchange plate, mutually close minor face edge or long limit edge joint weld are connected together, be not respectively a dielectric gas runner between Han Jie two minor faces and import and export, be respectively the secondary media gas flow between the two long limits and import and export.
The alternate anyway combination of plate that invention is provided, two minor face edges adjacent to each other or long limit edge joint weld be connected together be assembled into heat exchanger, two minor faces are respectively a dielectric gas and import and export, two long limits are respectively the secondary media gas inlet and outlet, a heat exchanger plates projection top and another heat exchanger plates projection top contact, contact at the bottom of the heat exchanger plates pit with at the bottom of another heat exchanger plates pit, because the convex top of flat-top hemisphere face shape or the distance of pit bottom and plate are 5～30 millimeters, the runner height of two plate compositions is 10～60 millimeters, form wide runner, the rectangular battle array of the projection of flat-top hemisphere face shape or pit distance, therefore it is visual to import and export two ends, be beneficial to gas communication, reduce resistance, be difficult for dust stratification,, also be convenient to clean even dust stratification is arranged.Adopt circular protrusions or bowl configurations, strengthen the support strength between plate, increased circulation area, increased the effective heat exchange area of plate simultaneously, gas flows between projection or pit, also can form high velocity turbulent flow when flow velocity is low, thereby improves the heat exchanger effectiveness of welded plate heat exchanger, produced simultaneously turbulent flow can produce from cleaning function dust stratification.
