Abstract
The utility model aims at providing an anti-corrosive tube plate for a shell-and-tube type heat exchanger. A brass layer is formed at the exterior of a traditional carbon steel tube plate, so as to solve the problem of easy corrosion when a tube plate body is in contact with a corrosive matter. The anti-corrosive tube plate for the shell-and-tube type heat exchanger comprises a tube plate body and a body groove. The anti-corrosive tube plate for the shell-and-tube type heat exchanger is characterized in that a main body is the tube plate body; the body groove is formed in the surface of the tube plate body; a copper plating layer is arranged at the interior of the body groove. The anti-corrosive tube plate has the beneficial effects that the non-ferrous metal with corrosion performance is heated and melted, and is tightly combined with carbons steel with strength index into a whole, and then the tube plate of the heat exchanger with strength and anti-corrosive performance is formed, thereby meeting the manufacturing requirement of the heat exchanger using the corrosive matter as a tube pass heat exchange medium, and saving the resource of non-ferrous metal.
Description
Technical field
The utility model relates to heat exchanger anticorrosion equipment and manufactures field, relates in particular to the anticorrosion tube sheet of a kind of shell-and-tube exchanger.
Background technology
While making shell-and-tube exchanger product, when tube side heat transferring medium is corrosivity object, heat exchanger tube must select with the tube sheet contacting with corrosivity object linking together with it high-alloy steel or nonferrous materials that possesses decay resistance, and so material cost is often very high also can consume nonferrous metal resource.This product is heated to base material carbon steel tube plate after the above temperature of iron brass fusing point by intermediate frequency heater, start to carry out auxiliary heating and melt iron brass making to flow in its sinking space processing in advance on base material carbon steel tube plate that is in a liquid state with auxiliary heating oxy arc, the cover material being fused into after liquid state closely combines with base material, after cover material cooling solidification, just become one with base material carbon steel tube plate, form a tube sheet that possesses decay resistance and meet heat exchanger strength demand.
Utility model content
Problem to be solved in the utility model is to provide the anticorrosion tube sheet of a kind of shell-and-tube exchanger, by corrosion-prone problem after solving the contact corrosion object of tube sheet own at conventional carbon steel pipe plate outer setting one deck brass.
The technical solution of the utility model is as follows: the anticorrosion tube sheet of a kind of shell-and-tube exchanger, comprises tube sheet main body and body recess; It is characterized in that described a kind of shell-and-tube exchanger is tube sheet main body by the main body of anticorrosion tube sheet, the surface of described tube sheet main body is provided with body recess, in described body recess, is provided with copper plate.
Further, described tube sheet main material is carbon steel alloy material.
Further, described copper plate material is iron brass material.
The beneficial effects of the utility model are: this product is that the non-ferrous metal that possesses decay resistance is made to its fusing and combined closely and be integral with the carbon steel that possesses intensity index by heating, become the heat exchanger tube sheet that simultaneously possesses intensity and decay resistance, take and meet the heat exchanger needs that tube side heat transferring medium is corrosivity object, and save nonferrous metal resource.

Fig. 1 is the utility model tube sheet agent structure schematic diagram.
Fig. 2 is the utility model tangent plane structural representation.
Wherein: 1, tube sheet main body, 2, body recess, 3, copper plate.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is made to brief description.
As shown in Figure 1, 2, the anticorrosion tube sheet of a kind of shell-and-tube exchanger, comprises tube sheet main body 1 and body recess 2; It is characterized in that described a kind of shell-and-tube exchanger is tube sheet main body 1 by the main body of anticorrosion tube sheet, the surface of described tube sheet main body 1 is provided with body recess 2, in described body recess 2, is provided with copper plate 3.
Described tube sheet main body 1 material is carbon steel alloy material.
Described copper plate 3 materials are iron brass material.
Effect and principle is installed: but brass material is that to have corrosion resistant metal hardness inadequate, and the hardness of carbon steel alloy material is fine but anticorrosion effect is poor, by copper-plating technique, carbon steel alloy and brass are closely as one, in installation, be the one side that is provided with copper plate can be docked on heat exchanger tube, like this in contact heat-exchanging pipe corrosive heat transferring medium be copper plate, so can improve the anticorrosion effect of tube sheet main body, and the part contacting with heat exchanger tube tube sheet main body is in addition all that its opposing external force effect forming with the manufacture of carbon steel alloy material is very strong, so this product is a heat exchanger tube sheet that can also improve whole acidproof effect in the situation that not lowering hardness, and the application of this product can effectively reduce the application of non-ferrous metal, saved cost of manufacture.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
