The heat exchanger of the utility model includes a shell, wherein, plastic pipe plates are provided at the upper and lower end of the shell, the plastic tube plates are provided with pores, the upper and lower pores are connected by a graphite heat exchange tube, and the interior diameter of the pore is smaller than the external diameter of the graphite heat exchange tube. The sealed ring of the utility model has simple structure, good sealing effect, and long life and the like advantages.
Description
Technical field
The utility model relates to a kind of parts of heat-exchange apparatus, relates in particular to a kind of auxiliary support member of heat exchanger.
Background technology
Heat exchanger is a kind of important operation equipment of industrial departments such as oil refining, chemical industry, the energy, the heat exchanger tube of heat exchanger of the prior art, deflection plate, tube sheet all are to adopt graphite or metal material usually, its equipment overall weight is big, antiseptic effect is bad, and be that the common thickness that is provided with of economical with materials, weight reduction deflection plate and tube sheet is less, less with the contact-making surface of heat exchanger tube, so stress ratio is more concentrated, the wearing and tearing of exchange heat pipe are bigger, and the support degree of exchange heat pipe is not enough, be easy to damage heat exchanger tube, need often to change.
The heat exchanger tube heating temperature difference of different parts during heat exchanger work, thereby the heat expansion elongation is also inequality, heat exchanger tube heat expansion difference in elongation causes deflection plate, the tube sheet stress rupture that is attached thereto, except the thermal (temperature difference) stress effect, linear expansion coefficient difference is excessive also to be a very important factor, makes temperature and stress be subjected to strict restriction.Usually at the junction of heat exchanger tube, deflection plate, tube sheet socket sealing ring, increase sealing effectiveness, but also increased cost simultaneously.
The utility model content
Technique effect of the present utility model can overcome above-mentioned defective, and a kind of heat exchanger is provided, and it can realize good sealing, antiseptic effect.
For achieving the above object, the utility model adopts following technical scheme: it comprises housing, and the two ends up and down of housing are provided with the plastics tube sheet, and the plastics tube sheet is provided with pore, two pores connect by the graphite heat exchanger tube up and down, and the internal diameter of pore is less than the external diameter of graphite heat exchanger tube.
Staggered interval is provided with deflection plate in the housing, and the graphite heat exchanger tube runs through deflection plate.The material of tube sheet and deflection plate adopts polytetrafluoroethylene (PTFE), polypropylene, polyvinyl chloride.Because the improvement of material can be born bigger pressure, rise sharply or during rapid drawdown, can make the distortion of tube sheet and deflection plate unlikely excessive in internal pressure, sealing effectiveness is fine, and the operating temperature of heat exchanger can reach 100 ℃, and operating pressure is brought up to 0.8Mpa.
Because tube sheet and deflection plate adopt plastic material, have good elasticity, so the internal diameter of the pore that is provided with on tube sheet and the deflection plate can be less than the external diameter of graphite heat exchanger tube, with the graphite heat exchanger tube directly cover connect and get final product, do not need to add sealing ring.Because plastics weight is lighter, the thickness with tube sheet and deflection plate increases like this, has improved itself and the contact area of heat exchanger tube, and the support heat exchanger tube is more steady.And the increase of area has disperseed the contact stress of heat exchanger tube and tube sheet, deflection plate, less friction, the service life of having improved heat exchanger tube.
Housing is provided with flange, and tube sheet adopts bolt to be connected with the flange of heat exchanger shell, is convenient to change the parts of damage like this, has overcome in the prior art owing to adopt the connected mode of welding, not easily changeable defective.
Heat exchanger tube and tube sheet, deflection plate not only can be tightly connected effectively, and heat exchanger tube is heated and can freely extends, and have avoided causing because of the effect of thermal (temperature difference) stress the destruction of connecting portion.
Plastic material is low with respect to metal material or its cost of graphite material, long service life, and its antiseptic effect is better.
Sealing ring of the present utility model has advantages such as simple in structure, good sealing effect, long service life.
Description of drawings
Fig. 1 is the general assembly drawing of heat exchanger.
The specific embodiment
The utility model comprises housing 1, and the two ends up and down of housing 1 are provided with plastics tube sheet 2, and plastics tube sheet 2 is provided with pore 5, and two pores 5 connect by graphite heat exchanger tube 3 up and down, and the internal diameter of pore 5 is less than the external diameter of graphite heat exchanger tube 3.
Staggered interval is provided with deflection plate 4 in the housing, and graphite heat exchanger tube 3 runs through deflection plate 4.The material of tube sheet 2 and deflection plate 4 adopts polytetrafluoroethylene (PTFE).Housing 1 is provided with flange 6, and tube sheet 2 adopts bolt to be connected with the flange of heat exchanger shell 1.
Because the improvement of structure and material can make the operating temperature of heat exchanger reach 80 ℃, operating pressure is brought up to 0.8Mpa.
Claims (4)
1. a heat exchanger comprises housing, it is characterized in that the two ends up and down of housing are provided with the plastics tube sheet, and the plastics tube sheet is provided with pore, and two pores connect by the graphite heat exchanger tube up and down, and the internal diameter of pore is less than the external diameter of graphite heat exchanger tube.
2. heat exchanger according to claim 1 is characterized in that staggered interval is provided with deflection plate in the housing, and the graphite heat exchanger tube runs through deflection plate.
3. heat exchanger according to claim 1 and 2 is characterized in that the material of tube sheet and deflection plate adopts polytetrafluoroethylene (PTFE) or polypropylene or polyvinyl chloride.
