Abstract
A kind of plate beam periphery flexible connecting structure, the four pillar construction heat exchanger frames including column and its with upper and lower pressure plate composition, heat exchanger plates beam is installed in the frame, column liner is installed on the inside of the column, pressure plate liner is installed between upper and lower pressure plate and column；The affixed insert of four peripheral end portion of heat exchanger plates beam, the insert and backing plate are affixed；The backing plate is affixed by the flexible steel in flat section tubing and column liner and pressure plate liner of sealing.The utility model structure is mainly used in the removable cover board welded plate type heat exchanger plate beam in four columns four sides and connect with heat exchanger frame, compared with prior art, divide journey simultaneously in realization heat exchanger media of both sides, it can bear bigger media of both sides pressure difference, and the thermal expansion difference generated between baffle beam and heat exchanger frame.
Description
Technical field
The utility model relates to welded plate type heat exchanger technical fields, refer in particular to a kind of plate beam periphery flexible connecting structure.
Background technique
Plate heat exchanger has the features such as compact-sized, heat transfer efficiency is high, is high-efficiency compact using plate as heat transfer element
Heat exchanger.With the raising of product structure continuously improved with manufacturing technology, welded plate type heat exchanger is more widely applied at present.
Sealing is formed around welded plate type heat exchanger plate and between plate beam and frame using welding manner, is consequently formed cold
Hot two kinds of fluid medium channels.Due to the unconventional rubber mat sealing structure using welding structure, welded plate type heat exchanger is available
In corrosive fluid, Applicable temperature, pressure limit are higher, are suitable for the demand that low parameter occasion waste heat recycles in petrochemical equipment.
However due to the limitation of original welded plate type heat exchanger structure, however it remains plate beam can not be eliminated with frame thermal (temperature difference) stress and be led
The problem of what is caused cannot be used for higher temperature occasion, and connecting portion cannot bear media of both sides High Pressure Difference.
Patent CN 202057215 discloses a kind of welded plate type heat exchanger.It is that corrugated cardboard sheet one is corresponding lateral interior curved
Song, another pair answers lateral outside sweep, and two in corrugated cardboard sheet adjacent flex face directly or inclined-plane extension site setting wing plate is constituted
Heat exchange plate, by 180 ° of 90 ° of adjacent heat exchange plate relative rotation or overturning, edge, which coincide partially to correspond to weld, forms plate beam, plate
Column cladding plate on wing plate and frame in beam is welded to connect.Plate beam and frame link position are subjected to media of both sides pressure difference,
This wing plate connection structure is limited by the thickness of plate, and is planomural pressure-bearing, in the case where bearing High Pressure Difference and larger thermal (temperature difference) stress,
This connecting portion easily deforms.
103791739 A of patent CN discloses a kind of welded plate type heat exchanger.Heat exchanger plates disclosed in it and frame bent plate
Between welded connecting have reached sealing and connection function, but its plate is directly connected to frame bent plate, and plate beam and frame generate
Thermal expansion can not discharge, in high temperature applicationss junction, there are larger thermal (temperature difference) stresses.In addition, heat exchanger plates weld the plate Shu Si to be formed
Each recessed notch need to be placed in the corresponding zipper shaped position of frame bent plate and welded by each corrugated cardboard sheet in angle, this connection structure pair
Plate beam assembly precision requires height, and welding structure is complicated.
Utility model content
The purpose of this utility model is to provide a kind of plate beam periphery flexible connecting structures, to solve welded plate type heat exchanger
Thermal expansion difference and media of both sides High Pressure Difference carry problem between plate beam and external frame.
The utility model solve the above problems the technical solution adopted is that:
A kind of plate beam periphery flexible connecting structure is changed including column and its with four pillar constructions of upper and lower pressure plate composition
Hot device frame, the frame is interior to install heat exchanger plates beam, column liner is installed on the inside of the column, between upper and lower pressure plate and column
Pressure plate liner is installed；The affixed insert of four peripheral end portion of heat exchanger plates beam, the insert and backing plate are affixed；The backing plate passes through sealing
Flexible steel in flat section tubing and column liner and pressure plate liner it is affixed.
The flexible steel in flat section tubing is circular arcs with arbitrary angles pipe or Ω shape pipe.
The beneficial effects of the utility model are:
Column liner plate in the utility model in plate beam and heat exchanger frame is using circular arcs with arbitrary angles pipe or Ω shape pipe
It is a kind of to be welded to connect.Compared with the prior art, the media of both sides pressure difference that the utility model can be born is bigger, baffle beam with
The thermal expansion effects generated between heat exchanger frame are more preferable.In turn, the utility model connection structure is simple, plate beam and heat exchanger frame
Column liner plate on frame connects only twice weld seam, requires plate beam assembly precision low.
The utility model effectively reduces welded plate type heat exchanger plate shell side junction thermal (temperature difference) stress, improves welded plate type and changes
Hot device bearing capacity, has the advantages of simple structure and easy realization, manufacturing cost is low.
Detailed description of the invention
Fig. 1 is welded plate type heat exchanger internal structure main view；
The top view of Fig. 2 reality Fig. 1；
Fig. 3 is the enlarged diagram in the portion I in Fig. 2, i.e. a kind of implementation structural schematic diagram of the utility model；
Fig. 4 is the enlarged diagram in the portion I in Fig. 2, is that the utility model another kind implements structural schematic diagram.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
Referring to Fig.1,2,3,4, a kind of plate beam periphery flexible connecting structure, including column and its with upper and lower pressure plate form
Four pillar construction heat exchanger frames, heat exchanger plates beam is installed in the frame, column liner 4, upper compression are installed on the inside of the column 3
Pressure plate liner 2 is installed between plate 1, lower pressure plate 9 and column 3；8 four peripheral end portion of heat exchanger plates beam welds insert 7, the edge
Block 7 and backing plate 6 weld；The backing plate 6 is welded by the flexible steel in flat section tubing 5 and column liner 4 and pressure plate liner 2 of sealing.
Referring to Fig. 3,4, the flexible steel in flat section tubing 5 is circular arcs with arbitrary angles pipe or Ω shape pipe.Flexible steel in flat section tubing 5 acts at all
It is that connecting plate beam 8 and frame form media of both sides channel, flexible structure can be while baffle beam and frame thermally expand
Bear media of both sides pressure difference.
