Abstract
The utility model relates to a multiple flow acid-base resistant tube still graphite heat exchanger, comprising an upper and a lower shell covers having different number of spacing tube cavities, and the form and the number of the cavities are determined by the process of the equipment. Threaded studs are used for tightly fixing the cavities, composite pipe plates and a cylinder flange gasket together. The upper shell cover, an upper composite pipe plate 2 and the cylinder flange gasket 9 are tightly fixed together via the threaded studs 7, graphite tubes 4 are arranged between the upper composite pipe plate 2 and a lower pipe plate 8 and connected by a sealed assembly 6. A deflector plate 5 is arranged in a cylinder body, and the graphite tubes are passed through the deflector plate 5 and arranged according to definite quantity and sequence.
Description
The utility model relates to the technology of chemical machinery aspect, and what be specifically related to is chemical anticorrosion graphite heat-exchange apparatus.
At present because the multipaths tubulation heat exchanger of graphite acid resistance of producing is better, but the poor-performing of anti-NaOH, we can say not alkaline-resistingly, graphite tube plate also is easy to cracking, can not satisfy the demands.
The purpose of this utility model discloses a kind of multipaths acid and alkali-resistance tubulation graphite heat exchanger and not only has the graphite-pipe characteristic of present domestic production outward and the caustic soda of ability 30% to reach it.
The purpose of this utility model can realize by following scheme;
Tube sheet lining stone China ink on matrix that novel device uses, by specific structure more in addition special PROCESS FOR TREATMENT the coefficient of expansion of its graphite and matrix is reached unanimity, so can not produce delamination.
Its architectural characteristic is: go up the pipe cavity that low head has number not wait, the form of its cavity and quantity determined by the flow process of equipment, with stud with itself and clad tubesheet, shell flange, pad is together firm.
The two ends that graphite-pipe is installed in pipe on the lower perforated plate link to each other with the existing tube sheet of potted component, and can flowing of pipe itself overcome because the unsafe factor that variations in temperature and difference variation are brought to equipment.
The utility model is compared except that the advantage with graphite heat exchanger with the tubulation graphite heat exchanger of existing domestic production, also has following advantage:
1, the scope of application has had very big improvement, and the acidproof scope from single expands the medium that acid and alkali-resistance or soda acid are used alternatingly to.
2,, solved the hidden danger that same equipment brings to equipment because of the swelling of variations in temperature due to big because of having adopted the structure of single tube sealing.
3, adopt graphite composite tube sheet, solved the worn-out end of tube sheet cracking and delamination.
Since above-mentioned special benefits, and the big device of this utility model graphite heat exchange is used more and more widely in industrial production.
Describe this shirt utility model content in detail to closing accompanying drawing below.
Upper cover 1, last clad tubesheet 2, shell flange, pad 9 tightly connects together by stud 7; Low head 10, following clad tubesheet 8, pad 9 connects together by stud 7 and cylindrical shell lower flange; Graphite-pipe 4 is installed in upper perforated plate 2 now between the tube sheet 8, by black box 6 connections; Split flow plate 5 is installed in the cylindrical shell, and graphite-pipe is therefrom passed through, and arranges by some and order.
Claims (1)
1, a kind of multipaths acid and alkali-resistance tubulation graphite heat exchanger comprises that the low head number does not wait the pipe cavity, and the form of its cavity and quantity are determined by equipment flowsheet.With stud with itself and clad tubesheet, the shell flange pad together firm and, upper cover, last clad tubesheet 2, shell flange pad 9 are by stud 7 firm connecting together, graphite-pipe 4 is installed in upper perforated plate 2 now between the tube sheet 8, by black box 6 connections; Split flow plate 5 is installed in the cylindrical shell, and graphite-pipe is therefrom passed through, and arranges by some and order.
