Abstract
The utility model discloses a heat exchange plate for a spiral-plate heat exchanger. The heat exchange plate comprises a substrate, wherein a metal coating layer for resisting corrosion, abrasion, oxidization and high temperature is respectively coated on the upper surface and the lower surface of the substrate. Therefore, the heat exchange plate can be widely applied to spiral-plate heat exchangers in the industries of metallurgy, coking, alcohol, food, chemical engineering and the like, reduces production cost and saves precious metal resources compared with integral cast or forged precious metal.
Description
Technical field
The utility model relates to a kind of heat exchanger plates, especially relates to the heat exchanger plates that is used for spiral heat exchanger.
Background technology
Spiral heat exchanger is to process two spirality channels by the metal plate coils of two Zhang Pings row, between the plate of two Zhang Pings row and plate, supports with spacing column, carries out heat exchange through the spiral wooden partition between the cold fluid and hot fluid.Spiral heat exchanger has removable and on-disconnectable two kinds of patterns, on-disconnectable formula spiral-plate heat exchanger relatively simple for structure, and the two ends of helical duct all weldering are dead; Demountable spiral-plate heat exchanger, except that the hermetically-sealed construction at helical duct two ends, other and on-disconnectable formula are identical.
During the spiral heat exchanger heat exchange, the cold and hot fluid of heat exchange flows through the both sides of spiral plate respectively, and a kind of fluid wherein is along the helical duct ecto-entad, flows out to central outlet; One other fluid then along helical duct by center inlet, flow out from inside to outside.Two kinds of fluids are pure reflux type and flow.Spiral heat exchanger is widely used, and can be used for industry heat exchange such as metallurgy, coking, alcohol, food, chemical industry.During with the spiral heat exchanger heat exchange; The working media of different industries (being cold and hot fluid) nature difference is very big; The working media that the working media that has has corrosivity, have has stronger oxidisability, and the working media that has contains the impurity to the helical duct impact injury, and the working media temperature that has is very high; And the heat exchanger plates material of spiral heat exchanger is carbon steel mostly, can't adapt to the environmental requirement of above-mentioned different industries working media.
Work in the working media environment of different industries for adapting to; Have in the prior art and select for use the metal material that adapts to the working media environment facies to process heat exchanger plates; For example can monoblock cast or heat exchanger plates such as forged titanium, nickel, cobalt, copper, aluminium, stainless steel; On the one hand the production cost of spiral heat exchanger is significantly improved but be processed into heat exchanger plates integral body heat exchanger plates such as titanium, nickel, cobalt, copper, aluminium, stainless steel, also waste a large amount of precious metals on the other hand, be unfavorable for resources conservation.
The utility model content
The technical problem that the utility model will solve provides a kind ofly can practice thrift precious metal, reduce the spiral heat exchanger production cost, has anticorrosion, wear-resisting, the anti-oxidant or resistant to elevated temperatures heat exchanger plates that is used for spiral heat exchanger again.
For solving the problems of the technologies described above, the utility model is used for the heat exchanger plates of spiral heat exchanger, comprises substrate, and the upper and lower surface of said substrate thermal spraying respectively is useful on anticorrosion, wear-resisting, anti-oxidant or resistant to elevated temperatures metal deposit layer.
Adopt the heat exchanger plates that is used for spiral heat exchanger of said structure; Because the upper and lower surface of substrate thermal spraying respectively is useful on anticorrosion, wear-resisting, anti-oxidant or resistant to elevated temperatures metal deposit layer; The spiral heat exchanger that therefore can be widely used in industries such as metallurgy, coking, alcohol, food, chemical industry; Precious metal heat exchanger plates with monoblock cast or forging is compared, and has reduced production cost, has practiced thrift the precious metal resource.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done to specify further.
Fig. 1 comprises that the utility model is used for the sectional structure sketch map of spiral heat exchanger of the heat exchanger plates of spiral heat exchanger.
Fig. 2 is that Fig. 1 I place structure is analysed and observe enlarged diagram.
The specific embodiment
Referring to Fig. 1, Fig. 2; Fig. 1 shows and comprises the sectional structure sketch map of spiral heat exchanger that the utility model is used for the heat exchanger plates of spiral heat exchanger, and spiral heat exchanger comprises the import 1 of cold medium, the outlet 2 of thermal medium; The import 3 of thermal medium; The outlet of cold medium is not shown, and is provided with spacing column 10 between 4, two heat exchanger plates of the heat exchanger plates of spiral heat exchanger.Fig. 2 shows the enlarged diagram of analysing and observe of Fig. 1 I place structure; Among Fig. 2; The heat exchanger plates that the utility model is used for spiral heat exchanger comprises substrate 5; The upper and lower surface of substrate 5 thermal spraying respectively is useful on anticorrosion, wear-resisting, anti-oxidant or resistant to elevated temperatures metal deposit layer 6, and experiment shows that the thickness of anticorrosion, wear-resisting, the anti-oxidant or resistant to elevated temperatures metal deposit layer of being used for of the heat exchanger plates of spiral heat exchanger is the needs that 0.5mm can satisfy the heat exchange environment.
Claims (2)
1. a heat exchanger plates that is used for spiral heat exchanger comprises substrate, it is characterized in that: the upper and lower surface of said substrate thermal spraying respectively is useful on anticorrosion, wear-resisting, anti-oxidant or resistant to elevated temperatures metal deposit layer.
2. according to the described heat exchanger plates that is used for spiral heat exchanger of claim 1, it is characterized in that: the thickness of said metal deposit layer is 0.5mm.
