The specific embodiment
As Figure 1-Figure 5, the lamella heat exchanger of dissymmetrical structure comprises shell side housing 1, is located at plate tube bank 8, tube side casing 4,6 in shell side housing 1; Plate tube bank 8 comprises some plate pipes 9, plate pipe 9 is comprised of section of jurisdiction 910,911 pressings of two cold formings, on section of jurisdiction 910,911, be distributed with the boss 907 of the depression that diamondwise arranges and the groove 908 being communicated with boss 907, the height of wherein said groove 908 is less than the height of boss 907, the flow channel for liquids 903 of the boss 907 on two sections of jurisdiction 910,911 and the corresponding formation plate of groove 908 pipe 9; Flow channel for liquids 903 in plate pipe 9 is descending runner and up runner for U-shaped is divided into; The upper end of plate pipe 9 is provided with feed liquor cavity 902 and the fluid cavity 901 being communicated with the two ends of flow channel for liquids 903, the bottom of plate pipe 9 is provided with and connects cavity 906, the uplink and downlink runner of flow channel for liquids 903 is communicated with by connecting cavity 906, and feed liquor cavity 902 and fluid cavity 901 consist of the groove correspondence on section of jurisdiction 907,908; The upper end of each plate pipe 9 is equipped with feed tube joint 904 and liquid outlet joint 905 is communicated with feed liquor cavity 902 and fluid cavity 901 respectively, the feed tube joint 904 of all plate pipes 9 and liquid outlet joint 905 are separately fixed on feed tube plate portion and drain pipe plate portion, and feed tube plate portion and drain pipe plate portion form tube sheet 7 global facilities; Tube side casing be divided into the fluid tube side casing 4 establishing the feed liquor tube side casing 6 of inlet 5 and establish liquid outlet 3 respectively correspondence be located on feed tube plate portion and drain pipe plate portion; Shell side housing 1 is provided with the clean window 2 of cleaning for plate tube bank, and clean window 2 is provided with cover plate 201.
When the present invention works, gas is from shell side housing 1 through plate tube bank 8, and liquid enters from the inlet 5 of feed liquor tube side casing 6, the U-shaped flow channel for liquids 903 in feed tube joint 904 enters plate pipe 9, from liquid outlet joint 905, flow into fluid tube side casing 4, through establishing liquid outlet 3 outflow heat exchangers.Gas and liquid carry out heat exchange in heat exchanger.
The preparation method of the lamella heat exchanger of dissymmetrical structure, comprise: the single plate pipe 9 that is provided with flow channel for liquids 903 and the feed tube joint 904 being communicated with flow channel for liquids 903 two ends and liquid outlet joint 905 is made parts in advance, tube sheet 7 is enclosed within and in the feed tube joint 904 of one group of plate pipe 9 and liquid outlet joint 905, is fixed into plate tube bank 8, again plate tube bank 8 is arranged in shell side housing 1, finally by tube side welding box body on tube sheet 7, tube side casing is divided into feed liquor tube side casing 6 and fluid tube side casing 4 respectively with that the feed tube joint 904 of plate pipe 9 and the feed tube plate portion of liquid outlet joint 905 and drain pipe plate portion are installed on tube sheet 7 is corresponding by dividing plate.This method can improve production efficiency and product quality and the maintain and replace of product simple.Solved the plate type heat exchanger of existing braze-welded structure, monolithic molding cannot monomer inspection and replacing, and the plate type heat exchanger of removable structure is subject in seal channel to alter logical impact, cannot detect concrete failure site, and the deficiency that lamella heat exchanger can only integral replacing.
The whole welding method that adopts stainless steel making and identical requirement of the present invention, corrosion resistance and heat-resisting quantity are splendid, the plate type heat exchanger that has overcome existing braze-welded structure is subject to the impact of cored solder, the temperature and the medium that use are all limited, and the plate type heat exchanger of removable structure cannot be used at high temperature and deep-etching, oxidation place by the impact of seal.And lamella heat exchanger is subject to structure influence, two sections of plate pipes all with Tube-sheet Welding, free wxpansion suffers restraints, and cannot be applicable to the defect in large temperature difference environment.
Plate middle part, without runner section blank position, adopts pressure welding mode, reduces plate lifting surface area, greatly improves the bearing capacity of plate.Having avoided existing braze-welded structure plate is to reduce lifting surface area by method for welding, affected by cored solder intensity and adhesion strength, the plate type heat exchanger of removable structure and lamella heat exchanger are to come passive reinforcement, the problem that bearing capacity is limited by additional pretension bolt pull bar or shell.
Should be appreciated that above-mentioned described specific embodiment, only in order to explain the present invention, is not intended to limit the present invention.
