Description
Technical field
The utility model belongs to heat exchanger technical field, is specifically related to a kind of heat exchanger as petrochemical equipment.
Background technology
Lamella heat exchanger is more and more extensive in the range of application of petrochemical industry, connection between existing multitube distance lamella heat exchanger floating end tube side adopts entirety to be fixedly connected with more, when pressure is larger, the connection constraints of plate bundle floating end will be made larger, stress is higher, in order to overcome this difficult point, must development of new lamella heat exchanger.
Summary of the invention
The utility model provides a kind of lamella heat exchanger, based on conventional tube shell heat exchanger, housing is the housing of conventional tube shell heat exchanger, and tube bank be with concavo-convex ripple plate with burr to burr, dimpled grain to dimpled grain overlap each other composition plate bundle, pipe, shell side medium move at respective passage respectively, the flow regime moment changes, and improves heat-transfer effect, adopts U-shaped pipe to connect between floating end tube side.
A kind of lamella heat exchanger, comprising: fixed tube sheet, plate bundle, pressure strip, gusset, segmental baffle, pull bar distance sink tube, sealed liner, square tube sheet, U-shaped pipe.The utility model solves the technical scheme that its technical problem adopts: what a kind of tube bank of lamella heat exchanger adopted is plate bundle, plate bundle to be overlapped each other to dimpled grain to burr, dimpled grain with burr by the plate with concavo-convex ripple to be welded to form, and the concavo-convex ripple of plate has different shapes; The two ends of plate bundle adopt sealed liner surrounding seal welding, and the upper and lower surface of each plate bundle is furnished with pressure strip, by link of boards, with fixed head bundle; Plate bundle stiff end sealed liner and fixed tube sheet integral solder, plate bundle floating end sealed liner and square Tube-sheet Welding, square tube sheet is furnished with pore; A plate Shu Weiyi tube side, adopts U-shaped pipe to connect between floating end tube side, U-shaped pipe two ends and square Tube-sheet Welding are separate between plate bundle, can move freely, and reduces floating end constraint; Be furnished with segmental baffle in housing, be connected spacing with pull bar with distance sink tube, segmental baffle be arranged so that shell side medium turbulent extent aggravates, carry out abundant heat exchange with tube side medium, improve heat transfer efficiency.
