Abstract
The invention relates to a heat exchange device for heat exchange between different fluid media, specifically to a compensating type heat exchanger with corrugated tubes. The heat exchanger comprises a shell, and a front tube plate and a rear tube plate that are connected at two ends of the shell, wherein straight tubes are disposed between the front and the rear tube plates, the outer sides of the front and the rear tube plates are respectively connected with a front shell head and a rear shell head; an inlet and an outlet of one medium are respectively disposed on the front and the rear shell heads, an inlet and an outlet of another medium are disposed on the shell; one ends of the tubes are connected with the front tube plate, and other ends of the tubes are connected with a movable tube plate, a corrugated tube is connected on the movable tube plate, and the other end of the corrugated tube is connected with the rear tube plate. The invention can compensate deformation of heat exchange elements due to temperature and pressure; and has the advantages of simple structure, reliable performance, long service life, good leak tightness and convenient cleaning.
Description
Technical field
The present invention relates to a kind of heat-exchange device that is used for carrying out between the different fluid medium exchange heat, specifically is a kind of corrugated pipe compensation type heat-exchanger.
Background technology
Tradition is used for the tube sheet that the heat exchanger of heat exchange between fluid generally comprises housing and is fixed on the housing two ends, is fixed with vertical tube bank between tube sheet, and fluid in the course of work in the tube bank and the fluid in the housing inner chamber carry out exchange heat.The heat exchanger of this structure when the two fluid media (medium) temperature difference and pressure reduction are big, produces the seepage of cracking and medium owing to be fixedly connected between housing, tube sheet and the tube bank easily because of tube bundle deformation, dependability is poor, the life-span is low.In order to improve the condition of work of heat exchanger components, improve dependability, the general at present structures such as movable tube sheets heat exchanger, U type pipe heat exchanger, stuffing box heat exchanger that adopt.In these heat exchanger structures: the movable tube sheets heat exchanger complex structure, cost is higher; Every pipe of U type pipe heat exchanger all curves the U type, and the utilization rate of tube sheet is lower, and easy cleaning not in the pipe is made difficulty, and the internal layer pipe has been broken and can not have been changed, thereby scrappage is higher; Be movable sealing between the moving head of the filler of stuffing box heat exchanger and tube bank, medium may leak outside by stuffing-box, and is inapplicable to inflammable, explosive, poisonous and valuable medium.
Summary of the invention
Technical problem to be solved by this invention is, provide a kind of simple in structure, can compensate distortion that heat exchanger components produces owing to temperature and pressure, use reliable, life-span length, good airproof performance, clean corrugated pipe compensation type heat-exchanger easily.
Corrugated pipe compensation type heat-exchanger of the present invention comprises a housing and is connected the front tube sheet and the back tube sheet at housing two ends, is provided with the straight line tube bank between the forward and backward tube sheet, and the outside of forward and backward tube sheet connects fore shell head and back cover head respectively; A kind of import and outlet of medium are set respectively on fore shell head and the back cover head, the import and the outlet of another kind of medium are set on the housing; One end of described tube bank is connected on the front tube sheet, and the other end of tube bank is connected on the moving tube sheet, is connected with one section bellows on the moving tube sheet, and the other end of bellows is connected with back tube sheet.Between described bellows and the back tube sheet is to be connected by a flange that is fixed on the bellows.Described housing, front tube sheet, back tube sheet, fore shell head, back cover head connect by bolt between them for dividing body structure.
The present invention is simple in structure, cost is low; Owing between tube bank and tube sheet, be provided with bellows, can compensate the distortion of tube bank effectively, improved the life of product of dependability; Because seal member is static sealing, has guaranteed that it has good sealing property; In addition, housing, tube sheet and the shell head of the tube bank of linear structure and branch body structure have also made things convenient for the dismounting and the cleaning of parts.
Description of drawings
Fig. 1 is a vertical section structure schematic diagram of the present invention.
The specific embodiment
As shown in the figure, this corrugated pipe compensation type heat-exchanger comprises a housing 1 and is connected front tube sheet 2, fore shell head 4, back tube sheet 3 and the back cover head 5 at housing two ends by bolt, be provided with tube bank 6 between the forward and backward tube sheet, the tube bank front end is connected on the front tube sheet 2, the tube bank rear end is connected on the moving tube sheet 7, connect one section bellows 8 on the moving tube sheet, the end of bellows is connected with back tube sheet 3 by flange 9.
