Abstract
The utility model relates to a heat-exchange plate used for fume waste-heat recovery. The heat-exchange plate used for fume waste-heat recovery comprises heat exchanger fins (1), a medium inlet (4) and a medium outlet (5). The heat-exchange plate is characterized in that stripes of the heat exchanger fins (1) comprise upwards convex spherical bulbs (2) and downwards concave spherical bulbs (3); the radius of the upwards convex spherical bulbs (2) is greater than that of the downwards concave spherical bulbs (3); and the downwards concave spherical bulbs are welded to form one heat-exchange plate through the two heat exchanger fins (1) according to a downwards concave spheroid, so as to form a medium passage. An inter-plate flow passage of the heat-exchange plate is a flexuose flow passage with inconstant cross sections, can effectively lead mediums to generate violent turbulent fluids under the circumstance that the flow speed is not high; the damage on a liquid boundary layer is accelerated, the heat-transfer process is intensified, the heat transfer coefficient of a heat interchanger is increased, and the scale formation is reduced; and the phenomenon that a traditional chevron heat-exchange plate is easy to cause the liquid dead area can be avoided.
Description
Technical field
The utility model relates to a kind of heat exchanger plates, particularly a kind of heat exchanger plates that is used for flue gas waste heat recovery.
Background technology
The plate line that is used for the heat exchanger plates of flue gas waste heat recovery at present is generally herringbone ripple, straight ripple, arc ripple, is the bar shaped ripple; The bar shaped line so the runner gap is less between plate, generally is no more than 10mm owing to be subjected to sheet material to limit can not do too big; Because the less pressure drop height in runner gap, be generally 20Kpa-100Kpa during water-water heat exchange, the pressure that heat exchanger plates bears is bigger, and heat exchange plate distortion, crackle take place easily.
Summary of the invention
The heat exchanger plates that is used for flue gas waste heat recovery that the purpose of this utility model just provides a kind of good heat-transfer, radiation loss is little, heat transfer temperature difference is little, thermal (temperature difference) stress is little, bearing capacity is good.
The purpose of this utility model is to realize by such technical scheme, comprise heat exchanger fin, medium import and media outlet, it is characterized in that: the plate line of described heat exchanger fin is made up of the spheric bulb of epirelief and recessed spheric bulb, the spheric bulb radius of epirelief is greater than recessed spheric bulb radius, two heat exchanger fins are welded into a heat exchanger plates according to recessed sphere to recessed spheric bulb, form a medium channel.
The spheric bulb that the utility model adopts the plate two sides to vary in size replaces traditional bar shaped ripple, describedly according to recessed sphere recessed spheric bulb is welded into a heat exchanger plates, forms a medium channel; When design, heat exchanger plates described in the utility model is welded at interval on the cavity of flue gas waste heat recovery apparatus, the interval between heat exchanger plates and the heat exchanger plates forms another exhaust gases passes, and promptly this passage all is made up of the spheric bulb of epirelief; In order more clearly to describe the utility model, we are called air duct at this passage with heat exchanger fin and heat exchanger fin welding formation, the passage that welding between heat exchanger plates and the heat exchanger plates is formed is called exhaust gases passes, when carrying out heat exchange, because the spheric bulb plate line radius in the exhaust gases passes is bigger, heat exchange area is bigger, and runner is tortuous more changeable, and high-temperature flue gas can more consumed energy in such runner.
Owing to adopted technique scheme, the utlity model has following advantage: runner is a runner that cross section is changeable, tortuous between plate of the present utility model, can effectively make flue gas produce strong turbulent flow in the little situation of flow velocity, accelerated the destruction of fluid boundary layer, not only strengthened diabatic process, improve the heat transfer coefficient of heat exchanger, and reduced fouling, avoided traditional chevron heat exchanger to occur the phenomenon in fluid dead band easily.
Description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1. heat exchanger fin; 2. the spheric bulb of epirelief; 3. recessed spheric bulb; 4. medium import; 5. media outlet;
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples: the utility model as shown in Figure 1, comprise heat exchanger fin 1, medium import 4 and media outlet 5, the plate line of described heat exchanger fin 1 is made up of the spheric bulb 2 of epirelief and recessed spheric bulb 3, spheric bulb 2 radiuses of epirelief are greater than recessed spheric bulb 3 radiuses, two heat exchanger fins 1 are welded into a heat exchanger plates according to recessed sphere to recessed spheric bulb, form a medium channel.
The spheric bulb that the utility model adopts the plate two sides to vary in size replaces traditional bar shaped ripple, and described two heat exchanger fins 1 are welded into a heat exchanger plates according to recessed sphere to recessed spheric bulb, form a medium channel.When the design plate type heat exchanger, on the cavity with heat exchanger plates described in the utility model interval welded plate type heat exchanger, the interval between heat exchanger plates and the heat exchanger plates forms another medium channel, and promptly this passage all is made up of the spheric bulb of epirelief; When carrying out flue gas waste heat recovery, we are called air duct with the passage of heat exchanger fin and heat exchanger fin welding formation, the passage that welding between heat exchanger plates and the heat exchanger plates is formed is called exhaust gases passes, advance because the spheric bulb plate line radius in the exhaust gases passes is bigger, heat exchange area is bigger, runner is tortuous more changeable, and medium is the more consumed energy of meeting in such runner, so high-temperature flue gas is flowed through from exhaust gases passes.Runner is a runner that cross section is changeable, tortuous between plate of the present utility model, can effectively make medium produce strong turbulent flow in the little situation of flow velocity, accelerated the destruction of fluid boundary layer, not only strengthened diabatic process, improved the heat transfer coefficient of heat exchanger, and reduced fouling, avoided traditional chevron heat exchanger to occur the phenomenon in fluid dead band easily.
Medium import of the present utility model 4 and medium go out 5 places, diagonal angle that are separately positioned on described heat exchanger plates.
The density that recessed spheric bulb distribution density described in the utility model distributes greater than the spheric bulb of described epirelief.
Described surface with heat exchanger fin of epirelief spheric bulb plate line one side described in the utility model is provided with the baffling groove.
One end on the surface of described heat exchanger fin with epirelief spheric bulb plate line one side described in the utility model scribbles refractory material, will scribble the arrival end of an end of refractory material as high-temperature flue gas usually, can reduce the damage that thermal expansion exchange backing causes like this.
Described heat exchanger plates described in the utility model is welded after by heat exchanger fin 1 doubling.The heat exchanger plates that is welded into after whole heat exchanger fin doubling has reduced the welding of exchange backing, has improved the heat resistance of heat exchanger plates.
