Preferred embodiment is introduced
Fig. 2 and Fig. 3 demonstrate the structure of heat exchanger.Tube type heat exchanger of the present invention mainly is made of one or more heat exchanger assemblies 1.Heat exchanger generally is made up of a plurality of heat exchanger assemblies 1 that are interconnected into the system for the distribution of commodities.Heat exchanger assemblies 1 comprises the outer tube 2 around one or more heat transfer tubes 3.Heat transfer tube 3 will be managed an end of 3 by tube sheet 4 and will be connected to each other.A plurality of heat transfer tubes 3 that the end is connected to tube sheet 4 have constituted products in circulation plug component 5.The two ends of sleeve pipe 2 are welded to each tube sheet 4.
Fig. 1 shows a plurality of heat exchanger assemblies 1 that are connected to each other the formation heat exchanger.The method that is adopted is depended in the heat exchange medium circulation of the products in circulation of heat exchanger adularescent arrow indication and black arrow indication, and heat exchange medium can heat or cooling products.Heat exchange medium can be by water or other liquid of different temperatures, perhaps with steam or other gas composition.Can also the backheat mode use according to heat exchanger of the present invention, promptly product is applied to products in circulation and heat exchange medium circulation, thus the cold product that already heated product by heating newly arrives, or turn around and carry out.
Products in circulation are circulations in heat transfer tube 3, and heat transfer tube 3 constitutes the major part of products in circulation plug component 5.Two adjacent products in circulation plug components 5 interconnect by product pipe bend 6, and the product pipe bend is fixed between two adjacent tube sheets 4 by bump joint.The pars intermedia branch 7 of product pipe bend 6 between two products in circulation plug components 5 be oval cross section preferably, the circular section preferably at two ends.Product pipe bend 6 can also be a circular cross-section in its whole length.The top oval product pipe bend of mentioning 6 has detailed introduction in Swedish patent application SE9703865-7.
Heat transport medium circulation circulation in sleeve pipe 2.Near two end points places, sleeve pipe 2 is provided with the circular hole 8 that has flange 9 at sleeve surface.Flange 9 is corresponding to connector 10.Connector 10 is made of straight-tube portion basically.Have groove at its two ends and be provided with packing ring or O type circle 11.The O type circle 11 that flange 9 is close to connector 10 two ends forms closely and flexible to a certain extent joint.
