Abstract
The utility model relates to a titanium heat exchanger tube box pass partition plate. The titanium heat exchanger tube box pass partition plate is a composite partition plate which is formed by compounding a layer of steel plate on each of the two surfaces of a titanium plate, and the titanium plate at one end of the composite partition plate is slightly longer than the steel plates on the two sides and is used for connecting the composite partition plate and a cylinder body of a heat exchanger tube box; weep holes are formed in the composite partition plate; the cylinder box of the heat exchanger tube box is formed by compounding a stainless steel plate, a titanium cladding layer and a titanium cladding cover plate from outside to outside in sequence; the composite partition plate is used for connecting the titanium plate which is connected with the cylinder body of the heat exchanger tube box with the stainless steel plate; the steel plates on the two sides of the composite partition plate are respectively welded with the titanium cladding cover plate. According to the titanium heat exchanger tube box pass partition plate, the problem that the cladding layer of the cylinder body at a welding seam easily falls off in a working state when a crude oil-early top oil and gas heat exchanger pass partition plate of an atmospheric and vacuum distillation device is a pure titanium partition plate is solved, and moreover, the cost is low.
Description
Technical field:
The utility model relates to heat exchanger bobbin carriage pass partition, what be specifically related to is titanium heat exchanger bobbin carriage pass partition.
Background technology:
Atmospheric and vacuum distillation unit crude oil-first top oil gas heat exchanger is movable tube sheets heat exchanger, this heat exchanger tube pass medium is first top oil gas (operating temperature is 80～150 ℃ of left and right), just top oil gas contains acid, stainless steel corrodes comparatively serious in this medium, and that the corrosion resisting property of titanium shows is very good, therefore tube side material selection titanium material, titanium is very active metal, under high temperature with carbon, hydrogen, oxygen, nitrogen etc. have very strong, during titanium material manufacture welding, start a large amount of hydrogen of inhaling, generate titantium hydride, titanium carbide, titanium oxide, the frangible compounds such as titanium nitride, thereby reduce plasticity and the toughness of titanium. cause embrittlement.Once titanium is stained with iron ion, become fragile, produce weld crack.Based on crude-first top oil gas heat exchanger (E-301A/B) process conditions, pass partition pressure at both sides is poor is 0.05Mpa, according to the computing formula of 5.2.3 pass partition thickness in GB151-1999, pure titanium dividing plate if, its block board thickness is 28 ㎜, descend in working order cylindrical shell multiple layer in commissure easily to come off, and the large cost of pure titanium block board thickness is higher.
Summary of the invention:
The purpose of this utility model is to provide titanium heat exchanger bobbin carriage pass partition, when this titanium heat exchanger bobbin carriage pass partition is used for solving atmospheric and vacuum distillation unit crude oil-first top oil gas heat exchanger pass partition and adopts pure titanium dividing plate, under duty, cylindrical shell multiple layer in commissure easily comes off, and the higher problem of cost.
The utility model solves the technical scheme that its technical problem adopts: this titanium heat exchanger bobbin carriage pass partition is the composite diaphragm consisting of each compound one deck steel plate of titanium plate two sides, and composite diaphragm wherein one end titanium plate is slightly longer than the steel plate of both sides, for being connected of composite diaphragm and heat exchanger bobbin carriage cylindrical shell, on composite diaphragm, be provided with drain hole; Heat exchanger bobbin carriage cylindrical shell is combined with each other and forms successively from outside to inside by corrosion resistant plate, the multiple layer of titanium, the topped plate of titanium, composite diaphragm is connected with corrosion resistant plate for the titanium plate being connected with heat exchanger bobbin carriage cylindrical shell, and the steel plate of composite diaphragm both sides welds with the topped plate of titanium respectively.
The utlity model has following beneficial effect:
When the utility model has solved atmospheric and vacuum distillation unit crude oil-first top oil gas heat exchanger pass partition and adopts pure titanium dividing plate, under duty, cylindrical shell multiple layer in commissure holds a caducous problem, and cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is drain hole structural representation in the utility model.
1 titanium plate, 2 steel plates, 3 drain holes, 4 corrosion resistant plates, the multiple layer of 5 titaniums, the topped plate of 6 titanium.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, this titanium heat exchanger bobbin carriage pass partition is the composite diaphragm consisting of each compound one deck steel plate 2 of titanium plate 1 two sides, adopt two-layered steel plates 2 folder one deck titanium plates 1 to form, and composite diaphragm wherein one end titanium plate 1 is slightly longer than the steel plate 2 of both sides, for being connected of composite diaphragm and heat exchanger bobbin carriage cylindrical shell, consult Fig. 2, on composite diaphragm, be provided with drain hole 3.
Heat exchanger bobbin carriage cylindrical shell is combined with each other and forms successively from outside to inside by corrosion resistant plate 4, the multiple layer 5 of titanium, the topped plate 6 of titanium, and outermost layer is corrosion resistant plate 4, and intermediate layer is the multiple layer 5 of titanium, and internal layer is the topped plate 6 of titanium.
The titanium plate 1 and corrosion resistant plate 4 welding of composite diaphragm for being connected with heat exchanger bobbin carriage cylindrical shell, the corrosion resistant plate 4 on the two connecting portion place heat exchanger bobbin carriage cylindrical shell is not covered by the multiple layer 5 of titanium and titanium overcoat 6, can directly be connected with the titanium plate 1 of composite diaphragm; The steel plate 2 of composite diaphragm both sides welds with the topped plate 6 of titanium respectively.
The utility model had both guaranteed the weld strength of dividing plate, had guaranteed again sealing.
