Detailed description of the invention
With embodiment, technical scheme is illustrated below in conjunction with the accompanying drawings.
As Figure 1-3, a kind of double-deck heat exchange shell structure of the present invention, including barrel shell 1 and inner bag 2, described interior
Gallbladder 2 is located at the interior and concentric setting of barrel shell 1, is connected and has some strengthening gussets 3 between the outer wall of inner bag 2 with the inwall of barrel shell 1,
The two side of barrel shell 1 is provided with fluid inlet 11 and fluid issuing 12；Open on inner bag 2 sidewall relative with described fluid inlet 11
Having some tap holes 21, some tap holes 21 are the most equally spaced distributed on the sidewall of inner bag 2；With described fluid issuing
12 relative inner bag 2 sidewalls are provided with some explosion reliefs 22, and some explosion reliefs 22 are sequentially distributed the sidewall at inner bag 2 vertically
On；Described inner bag 2 is fixedly connected in barrel shell 1 by strengthening gusset 3, can be abound with heat exchanger tube to improve heat exchange area in inner bag 2
Utilization, and some strengthening gussets 3 support connect while by inner bag 2 outside barrel shell 1 inner chamber be divided into and some independently lead to
Road, heat transferring medium region be directly facing inner bag 2 sidewall sections with some tap holes 21, tap hole via fluid inlet 11 after entering
21 along the axially arranged of inner bag 2 and the whole shell side of uniform inner bag 2, and some tap holes 21 form the medium flow channel of inner bag 2,
Thus the flow direction controlling heat transferring medium makes it uniformly wash away the heat exchanger tube in inner bag 2；Described explosion relief 22 is as the medium of inner bag 2
Reserving passage, explosion relief 22 uses the flux design that relative tap hole 21 is bigger, it is possible to decrease in inner bag 2 and its both sides barrel shell 1
The pressure differential in chamber, the circulation of raising heat transferring medium and circulation efficiency and then lifting heat transfer effect.
The sidewall sections that tap hole 21 is distributed on described inner bag 2 is its distributary division, and the distributary division both sides of inner bag 2 are equipped with
Corresponding strengthening gusset 3, and the outer side edges of the two strengthening gusset 3 is connected to barrel shell 1 inwall of fluid inlet 11 both sides
On；Barrel shell 1 inner chamber between fluid inlet 11 and shunting zone is separated in phase by described two the strengthening gussets 3 corresponding with distributary division
To independent passage, and this passage portion space of barrel shell 1 is as the dispersion area after heat transferring medium entrance, and heat transferring medium is from fluid
Enter inner bag 2 by corresponding some tap holes 21 in import 11 enters barrel shell 1 and in dispersion area, thus avoid heat transferring medium
Directly wash away heat exchanger tube, make the heat exchanger tube in the whole shell side of inner bag 2 simultaneously participate in heat exchange process to improve heat exchange efficiency.
The sidewall sections that explosion relief 22 is distributed on described inner bag 2 is its relief part, and the relief part both sides of inner bag 2 are equipped with
Corresponding strengthening gusset 3, and the outer side edges of the two strengthening gusset 3 is connected to barrel shell 1 inwall of fluid issuing 12 both sides
On；Described two the strengthening gussets 3 corresponding with relief part, as the symmetric support structure of distributary division both sides strengthening gusset 3, can carry
High overall stability and structural strength；The gusset 3 of the two strengthening simultaneously is by the barrel shell 1 between relief part and fluid issuing 12
Chamber separates in another relatively independent passage, and this passage portion connection inner bag 2 of barrel shell 1 and fluid issuing 12, make through
The medium of heat exchange can quickly flow out barrel shell 1, it is to avoid the erosion control baffle plate in existing heat exchanger structure, simplifies mechanism and arranges.
Axially disposed and strengthening gusset 3 the interior outer side edges of described strengthening gusset 3 is respectively welded at inner bag 2 outer wall and barrel shell
On 1 inwall；Can be accurately positioned the inner bag 2 relative position at barrel shell 1 by symmetrically arranged strengthening gusset 3, the present invention preferably adopts
With two groups of shunting zones the most corresponding and the strengthening gusset 3 in release of pressure district, stability and the intensity of structure can be improved, and be conducive to assembling
The convenience of welding.
Having some through holes 32 on described strengthening gusset 3, described through hole 32 is for connecting the cylinder of strengthening gusset 3 both sides
Shell 1 inner space, it is to avoid pressure differential occurs in the inner space producing barrel shell 1 and inner bag 2, improves structural stability with rationally
Property.
The inboard limit of described strengthening gusset 3 is provided with the connection sheet 31 of integrative-structure L-shaped with it, the sidewall of inner bag 2
It is provided with some and strengthening gusset 3 weld seam mouth 23 one to one, connects inner bag 2 sidewall weld at sheet 31 and weld seam mouth 23 solid
Fixed；Currently preferred strengthening gusset 3 uses one bending and molding structure, can be first welded on by strengthening gusset 3 man-hour adding
On barrel shell 1 inwall, inner bag 2 is installed the most again and is welded by sealing mouth 23, it is to avoid between inner bag 2 and barrel shell 1, space is relatively
The little difficulty of processing caused, to improve efficiency of assembling, improves the inner bag 2 space accounting in barrel shell 1 and heat exchange further
Area.
Described some explosion reliefs 22 are the hatch frame of rectangle, and the flux summation of some explosion reliefs 22 is more than some tap holes
The flux summation of 21；Described inner bag 2 by the explosion relief 22 of bigger flux so that between fluid inlet 11 and fluid issuing 12
Reduce flow resistance, improve the efficiency that heat transferring medium flows in inner bag 2 and barrel shell 1, it is to avoid the generation of turbulent flow, simplify structure
Improve heat transfer effect.
The above is only the better embodiment of the present invention, thus all according to the structure described in present patent application scope,
The equivalence that feature and principle are done changes or modifies, in the range of being all included in present patent application.
