Abstract
The utility model relates to a new link construction of the heat exchanging tube and the tube plate, which realizes connection by arranging seal ring and thrust ring in the counter bore on the tube plate. The utility model is characterized in that the heat exchanging tube can be changed momentarily and conveniently without increasing device cost and reducing device maintaining cost. The utility model is suitable for all atmospheric heat exchanger, and the advantage is much prominent to the heat exchanger being made of special material, as this structure substitutes the welded connection the requirements to tube plate materials are greatly reduced, that the device final cost is greatly reduced. The utility model has simple structure, convenient mounting and repairing and good economic practicability.
Description
Technical field:
The utility model relates to heat transfer technology.
Background technology:
At present, in heat transmission equipments such as shell-and-tube heat exchanger or movable tube sheets heat exchanger, extensively the heat exchanger tube that adopts is welding and expanded joint with the connected mode of tube sheet, also can adopt welded and rolled tube joint and usefulness under high-temperature and high-pressure conditions, does not generally consider to manage, the pressure and temperature situation of shell side.In addition, these methods also are applicable to the normal pressure heat exchanger that temperature is not high.Develop the heat exchanger that many special materials are made in recent years in succession, as be used for the titanium heat exchanger of industries such as seawater, chlor-alkali and acetic acid.Will consider the seawater corrosion problem because of this class heat exchanger, so heat exchanger tube need adopt the titanium pipe, and titanium and other metal do not possess solderability.In order to guarantee being welded to connect of titanium tube and tube plate, tube sheet also will adopt full titanium or titanium composite plate, and consequently equipment cost significantly improves.On the other hand, even adopted titanium tube heat exchanger, also can take place inevitably the corrosion failure of heat exchanger tube and damage (the annual whole nation damage because of heat exchanger tube or fouling stop up changes the heat exchanger of restraining and reaches about 1000).Adopt the full titanium or the composite ti pipe plate of welding point, when changing tube bank, generally be difficult to utilize again original tube sheet, because of the heat exchanger tube for the perforation that is corroded individually can only stop up, for the moment can't realize replace tubes, along with the equipment growth of service time, the plugging number is on the increase, when tube bank is changed, need all be changed tube sheet and heat exchanger tube, thereby cause the increase of maintenance of equipment maintenance cost.
Summary of the invention
The purpose of this utility model just provides a kind of syndeton of novel heat exchange tube and tube plate, and its main feature is not increase equipment cost and reducing under the prerequisite of equipment maintenance cost, can change heat exchanger tube at any time easily.
The utility model is achieved in that tubesheet holes is a stepped hole, is provided with sealing ring between heat exchanger tube and tube sheet stepped hole, is provided with the thrust circle in the stepped hole end.
The utility model adopts ring structure to connect heat exchanger tube and tube sheet, is applicable to that all pipes, shell side pressure are less, and the working media temperature is not high, solderability difference and the heat exchanger that needs frequent replacing tube bank between tube sheet and the heat exchanger tube, promptly take off sealing ring, with regard to replaceable heat exchanger tube, very convenient.And the heat exchanger of making for special material, its meaning is even more important.Because this structure has replaced being welded to connect, thereby the material instructions for use of tube sheet is reduced greatly, as when being used on the titanium corrugated tube heat exchanger of industries such as seawater, chlor-alkali, heat exchanger tube adopts the titanium material, tube sheet can adopt casting pig surface brush corrosion-inhibiting coating (seawater corrosion resistance), apparatus casing, bobbin carriage can adopt the carbon steel preservative treatment, the equipment total cost is compared with the composite ti pipe board device declined to a great extent, and just account for 1/10th of full titanium heat exchanger cost.When corrosion failure appears in indivedual heat exchanger tubes, only need take off sealing ring, therefore just replaceable heat exchanger tube greatly reduces the plant maintenance maintenance cost.This utility model is simple in structure, and installation and maintenance are convenient, have good economic and practical.
Description of drawings:
A kind of embodiment schematic diagram that accompanying drawing provides for this utility model.
Specific embodiments:
As shown in drawings, the tubesheet holes on the tube sheet 1 is made stepped hole 2, two O type rubber seal 4 are set between heat exchanger tube 3 and tube sheet stepped hole 2, a thrust circle 5 is set in tube sheet stepped hole 2 ends.
Claims (1)
1. the syndeton of a novel heat exchange tube and tube plate is characterized in that tubesheet holes is a stepped hole, is provided with sealing ring between heat exchanger tube and tube sheet stepped hole, is provided with the thrust circle in the stepped hole end.
