Abstract
The utility model relates to a novel high corrosion-resistance tubular heat exchanger, which is changed from a lining on the basis of an original glass tubular heat exchanger and an enamel glass tubular heat exchanger. The novel high corrosion-resistance tubular heat exchanger overcomes the disadvantages that the original glass tubular heat exchanger with low pressure bearing performance is easy to be crushed, and the original enamel glass tubular heat exchanger has complicated processing technology, low rate of finished products and unreliable corrosion resistance. Production costs can be reduced, heat-transfer efficiency is increased, and the service life of the heat exchanger is prolonged.
Description
The utility model is a kind of tubular heat exchanger.
Traditional tubular heat exchanger mainly is made up of housing and tube bank, and the medium of two kinds of different temperatures different pressures carries out heat exchange by tube side and shell side respectively.But for mordant medium, heat exchanger will be made with resistant material, perhaps tube side and shell side be carried out the anticorrosion construction processing.
Though the heat exchanger with the glass tube manufacturing has good Corrosion Protection, but heat exchanger tube will be sealed on the tube sheet with polytetrafluoroethylene (PTFE) and fluorine rubber ring respectively when installing, deflection plate also will be used polytetrafluoroethylene (PTFE), so not only manufacturing cost height, and polytetrafluoroethylene (PTFE) has also limited the application of this heat exchanger at aspects such as medicine, food industry.Simultaneously, because some weakness of glass material itself, the glass heat exchanger pressure-bearing is low, and is easily broken in transportation and the installation process.
Enamel is a kind of nature of glass glaze to be sprayed on the steel matrix surface after fusion and a class composite that forms, and it has corrosion resistance preferably under certain temperature and pressure.But it is difficult making this heat exchanger with glass lined method merely, and this mainly is:
(1), after the enamel construction is carried out in transition continuously inside from the tube sheet outside to pipe, because the glass-lined coating of tube interior will produce defectives such as pin hole inevitably, and at present these defectives in the long tube are not had the method for inspection accurately, also can't carry out effective for repairing even found these defectives simultaneously, thereby make the corrosion resistance of the product that finally obtains unreliable.
(2), long tube in ward off prematurity still on the present technology of problem, mainly be to have warded off behind the glass except that above-mentioned defective is arranged, also usually cause the excessive deformation of pipe, yield rate is low.
(3), many tube-to-tube sheet connections carry out enamel firing after welding, and almost are impossible in view of present enamel firing technology.Because the tube-to-tube sheet connection junction is an area of stress concentration, " burst porcelain " phenomenon at this place can be greatly, and tube bank also can be scratched to become and can't be satisfied the requirement of bearing pressure because of generation.
Task of the present utility model provides a kind of novel corrosion-resistant heat exchanger, it can overcome the shortcoming of bare glass tubular heat exchanger and enamel tubular heat exchanger, further improve the Corrosion Protection of heat exchanger and enlarge its application, reduce production costs effectively.
Task of the present utility model realizes in the following way:
1, the enamel heat exchanger tube to former heat exchanger changes, it is become the metal liner glass tube, so not only avoided long tube in ward off problem, some defectives of having avoided the enamel melting to burn till in the construction being produced, and the corrosion resistance of metal liner glass tube is good, and skin resistance is little, the adhesion material, not having pin hole, is comparatively desirable with it as heat exchanger tube therefore.
2, many metal liner glass tubes are connected with metal tube sheets, make its tube bank that constitutes heat exchanger, make the problem that almost can't realize in the enamel construction become simple thus.
3, tube sheet is carried out local enamel construction processing, Local treatment can reduce the stress of tube-to-tube sheet connection junction like this and concentrate only for the outer surface of tube sheet, reduces " burst porcelain " phenomenon at this place effectively.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the transverse cross-sectional view of a kind of structure of this corrosion-resistant multitubular parallel operation.
With reference to Fig. 1, the utility model is made up of bobbin carriage (1), tube sheet (2), tube bank (3), housing (4) and deflection plate (5), bobbin carriage (1) inner surface enamel wherein, and tube sheet (2) outer surface enameling glass, restraining (3) is the metal liner glass tube.
During use, Korrosionsmedium is walked tube side, and bobbin carriage (1) inner surface, tube sheet (2) outer surface and tube bank (3) inner surface have just constituted continuous flawless Corrosion resistant linings layer, thereby reach effect of the present utility model and purpose.
Claims (2)
1, the corrosion-resistant multitubular heat exchanger is a kind of fixed tube-sheet exchanger, and it mainly is made up of bobbin carriage (1), tube sheet (2), tube bank (3), housing (4) and deflection plate (5) etc., and the heat exchanger tube that it is characterized in that this heat exchanger is the metal liner glass tube.
2, with the contacted all surface of medium continuous nature of glass anti-corrosion coating is arranged all in the corrosion-resistant multitubular heat exchanger according to claim 1, it is characterized in that the surperficial enamel of tube sheet (2), tube sheet (2) is vitreous composite with the junction of tube bank (3).
