Abstract
The utility model relates to a flange structure of a titanium sealing ring-tube tank of a titanium material heat exchanger. The flange structure consists of a flange body, a lining tube and a lining ring, wherein the lining tube is arranged on the internal wall of the flange body, an annular groove is formed between the lining tube and the flange body, a titanium backing plate is arranged in the annular groove, the lining ring and the flange body are connected by adopting sunk screws made from titanium, the titanium backing plate is sealed by the lining ring, the lining ring and the lining tube are butted and then are connected through welding, and outer edges of junctions of the lining ring and the flange body are welded. The flange structure has the advantages that the problem that corrosion is easy to cause due to the fact that a carbon-steel flange is in contact with an internal medium in a working state of flange structures of crude oil-initially-topped oil gas heat exchange tube tanks of atmospheric and vacuum distillation units is solved, and the condition that the medium is not in contact with carbon steel is ensured.
Description
Technical field:
The utility model relates to heat exchanger bobbin carriage flange arrangement, what be specifically related to is titanium heat exchanger titanium sealing ring channel flange structure.
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, and heat exchanger bobbin carriage flange arrangement descends simple steel flange to contact and easily cause etching problem with interior media in working order.
Summary of the invention:
The purpose of this utility model is to provide titanium heat exchanger titanium sealing ring channel flange structure, this titanium heat exchanger titanium sealing ring channel flange structure be used for solving atmospheric and vacuum distillation unit crude oil-first top oil gas heat exchanger channel flange structure in working order under, simple steel flange contacts the problem that easily causes corrosion with interior media.
The utility model solves the technical scheme that its technical problem adopts: this titanium heat exchanger titanium sealing ring channel flange structure is made up of flange body, lining, grommet, lining is arranged on flange body inwall, between lining and flange body, be provided with cannelure, in cannelure, be provided with titanium backing plate, grommet adopts titanium sunk screw processed to be connected with flange body, grommet seals titanium backing plate, and grommet is welded to connect after docking with lining, the outer rim welding of grommet and flange body junction.
The utlity model has following beneficial effect:
1, the utility model solved atmospheric and vacuum distillation unit crude oil-first top oil gas heat exchange bobbin carriage flange arrangement in working order under, simple steel flange contacts the problem that easily causes corrosion with interior media, guarantee that medium does not contact with carbon steel.
2, the utility model good seal performance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1 flange body, 2 linings, 3 grommets, 4 titanium backing plates, 5 sunk screws.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, this titanium heat exchanger titanium sealing ring channel flange structure is by flange body 1, lining 2, grommet 3 forms, lining 2 is arranged on flange body 1 inwall, lining 2 is kept apart flange body 1 and medium, between lining 2 and flange body 1, be provided with cannelure, in cannelure, be provided with titanium backing plate 4, grommet 3 adopts titanium sunk screw 5 processed to be connected with flange body 1, grommet 3 is arranged on flange body 1 card place, specifically be arranged between the bolt hole on flange duct and flange, grommet 3 seals titanium backing plate 4, grommet 3 is welded to connect after docking with lining 2, grommet 3 adopts silver brazing with the outer fringe seal of flange body 1 junction, improve sealing property.
In the utility model, grommet 3 materials are TA10,, the material of flange body 1 is 16Mn III, adds man-hour, lining 2 is placed on flange body 1 inwall, process wide 10 ㎜ in flange body 1 and grommet 3 junctions, the cannelure of the degree of depth 3 ㎜, groove the inside is filled into titanium backing plate 4, then lining 2 and grommet 3 butt welding, grommet 3 connects and adopts titanium sunk screw processed to be connected with flange body 1, then with argon arc welding, screw is sealed, and grommet 3 adopts silver brazing with the sealing of flange body 1 along the outer rim of grommet 3.This kind of structural design, can guarantee that medium does not contact with carbon steel, can guarantee again the sealing of lining and basic unit and sealing surface.
