Description
Technical field
The utility model relates to heat exchanger manufacturing technology field, particularly relates to a kind of heat exchanger of band coating.
Background technology
Heat exchanger is used to make heat be delivered to cold fluid from hot fluid, with the device of the technological requirement of satisfied regulation.Fluid flows through heat exchanger makes its surface be corroded usually, and its surface coating coatings can protect body.Although the heat exchanger of the band coating occurred in the market reduces the corrosion failure of fluid to heat exchanger, combination property also can not meet the needs of productive life far away.
There is following shortcoming in the heat exchanger of existing band coating:
One, the curing of coatings of existing heat exchanger is poor, and adhesive ability is strong, chemical stability and antioxygenic property poor, once the coating on its surface uses for a long time under the adverse circumstances such as high temperature, will cause that lustrous surface is eclipsed, color is unstable;
Two, antiseptic property is poor, anti-adhesion performance is poor;
Three, wearability is bad, does not have good wear-resistant protection effect for base material.
Summary of the invention
The utility model provides that a kind of dielectric properties are good, set shrinkage factor is little, to product size good stability, heat exchanger to alkali and most of solvent-stable, corrosion-resistant, wear-resisting difference, mechanical behavior under high temperature is good, the good antiscale property cycle is long, heat transfer rate is fast band coating.
For solving the technical problem existed in above-mentioned technology, the concrete technical scheme of employing is:
A heat exchanger for band coating, described coating is followed successively by epoxy coating, carbon-to-carbon composite coating, polytetrafluorethylecoatings coatings from inside to outside; Described heat exchanger comprises multiple pipe, two tube sheets and housing; Described tube sheet is fixed on enclosure interior, described multiple pipe is arranged parallel to each other and is fixed on tube sheet, the two ends of described housing are respectively equipped with left end socket, right end socket, described left end socket upper end is provided with cold fluid import, lower end is provided with cold fluid outlet, described housing is provided with hot fluid import near the top of right end socket, is provided with hot fluid outlet ports near the bottom of left end socket.
Described carbon-to-carbon composite coating surface is provided with the silicon carbide whisker coating of one deck densification.
Described epoxy coating, carbon-to-carbon composite coating, polytetrafluorethylecoatings coatings thickness be 7 μm to 1.5mm.
The thickness of described coat of silicon carbide is 5 μm to 7 μm.
Described left end socket inside is provided with dividing plate.
Described enclosure interior is staggeredly distributed with multiple baffle plate.
The height of described baffle plate is less than diameter of the housing.
By adopting such scheme, compared with prior art, its technique effect is the heat exchanger of band coating of the present utility model:
By coating epoxy coating, make heat exchanger dielectric properties good, set shrinkage factor is little, product size good stability, and pliability is better, to alkali and most of solvent-stable; By coating carbon-to-carbon composite coating, make heat exchanger high temperature resistance, corrosion-resistant, wear-resisting difference, particularly carbon-to-carbon composite coating is coated with silicon carbide whisker coating, it has, and high strength, high rigidity, high elastic modulus and density are low, corrosion-resistant, stable chemical nature, oxidation-resistance property by force can good characteristics; Externally coated polytetrafluorethylecoatings coatings has the feature of antiacid alkali resistant, anti-various organic solvent, is dissolved in all solvents hardly, substantially increases the physical life of heat exchanger.
Internal heat exchanger is staggered is provided with multiple baffle plate, flows out, substantially increase heat exchange efficiency after hot fluid can be made to enter housing after repeatedly circulating.
