Abstract
The utility model discloses an anti-corrosion shell-and-tube heat exchanger, which comprises a cold and heat medium inlet and a cold and heat medium outlet, wherein a heat exchange tube is arranged in a shell of the heat exchanger; two ends of the heat exchange tube are arranged on a tube plate; end covers are arranged on two sides of the tube plate; and the tube plate comprises a carbon steel tube plate base metal layer and an anti-corrosion layer compounded on a surface of the carbon steel tube plate base metal layer. Due to the adoption of the anti-corrosion shell-and-tube heat exchanger with the structure, the tube plate comprises the carbon steel tube plate base metal layer and the anti-corrosion layer compounded on the surface of the carbon steel tube plate base metal layer, so that the tube plate can be prevented from being corroded, and the normal operation of the shell-and-tube heat exchanger cannot be affected by the corrosion of the tube plate.
Description
Technical field
The utility model relates to a kind of shell-and-tube heat exchanger, especially relates to a kind of corrosion-resistant pipe shell-type heat exchanger.
Background technology
The structure of shell-and-tube heat exchanger of the prior art mainly comprises housing, housing has the import and export of hot and cold medium, in the housing of described heat exchanger, there is heat exchanger tube, the two ends of heat exchanger tube are loaded on tube sheet, the both sides of tube sheet have end cap, shell-and-tube heat exchanger of the prior art is widely used in petrochemical industry, but the high-temperature oxydation in crude refining production process, sulfide and aphthenic acids environment, corrosion strength to equipment is larger, especially the installation heat exchanger tube place of tube sheet is subject to corrosiveness easily to produce leakage even to ftracture, affected the normal operation of heat exchanger.
Utility model content
The technical problems to be solved in the utility model is to provide the corrosion-resistant pipe shell-type heat exchanger that a kind of tube sheet has corrosion resistance.
For solving the problems of the technologies described above, a kind of corrosion-resistant pipe shell-type of the utility model heat exchanger, the import and export with hot and cold medium, in the housing of described heat exchanger, there is heat exchanger tube, the two ends of heat exchanger tube are loaded on tube sheet, the both sides of tube sheet have end cap, and described tube sheet comprises carbon steel tube plate mother metal layer and is compounded in the anticorrosion layer formation on carbon steel tube plate mother metal layer surface.
Adopt the corrosion-resistant pipe shell-type heat exchanger of said structure, because comprising carbon steel tube plate mother metal layer and the anticorrosion layer that is compounded in carbon steel tube plate mother metal layer surface, described tube sheet forms, therefore tube sheet can not be corroded, and can not affect because of the corrosion of tube sheet the normal operation of shell-and-tube heat exchanger.
accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is office's sectional structure schematic diagram of a kind of shell-and-tube heat exchanger of the utility model.
Fig. 2 is the tube sheet office sectional structure schematic diagram of a kind of shell-and-tube heat exchanger of the utility model.
The specific embodiment
Referring to Fig. 1, Fig. 2, a kind of corrosion-resistant pipe shell-type of the utility model heat exchanger, the import and export 6,7,8,9 with hot and cold medium, in the housing of described heat exchanger, there is heat exchanger tube 3, the two ends of heat exchanger tube 3 are loaded on tube sheet 4, the both sides of tube sheet 4 have end cap 5, and described tube sheet 4 comprises carbon steel tube plate mother metal layer 2 and is compounded in anticorrosion layer 1 formation on carbon steel tube plate mother metal layer 2 surface.
