Embodiment
Technical scheme is illustrated with embodiment below in conjunction with the accompanying drawings.
As shown in Figs. 1-3, a kind of double-deck heat exchange shell structure of the present invention, including barrel shell 1 and liner 2, it is described interior
Courage 2 is arranged in barrel shell 1 and concentric setting, and some reinforcing gussets 3 are connected between the outer wall of liner 2 and the inner wall of barrel shell 1,
The two side of barrel shell 1 is equipped with fluid inlet 11 and fluid outlet 12；Opened on 2 side wall of liner opposite with the fluid inlet 11
There are some tap holes 21, some tap holes 21 are equally spaced distributed on the side wall of liner 2 vertically；With the fluid outlet
12 opposite 2 side walls of liner are equipped with some explosion reliefs 22, and some explosion reliefs 22 are sequentially distributed the side wall in liner 2 vertically
On；The liner 2 is fixedly connected in barrel shell 1 by strengthening gusset 3, and heat exchanger tube can be abound with to improve heat exchange area in liner 2
Utilization, and it is some strengthen gusset 3 and be divided into 1 inner cavity of barrel shell in the outside of liner 2 while supporting and connecting some independently lead to
Road, heat transferring medium region be directly facing 2 sidewall sections of liner with some tap holes 21, tap hole after entering via fluid inlet 11
21 form the medium flow channel of liners 2 along the axial setting of liner 2 and the whole shell side of uniformly distributed liner 2, some tap holes 21,
So as to control the heat exchanger tube that the flow direction of heat transferring medium makes it uniformly wash away in liner 2；Medium of the explosion relief 22 as liner 2
Passage is reserved, explosion relief 22 can be reduced in liner 2 and its both sides barrel shell 1 using the flux design of 21 bigger of opposite tap hole
The pressure differential of chamber, improves the circulation and circulation efficiency and then lifting heat transfer effect of heat transferring medium.
The sidewall sections that tap hole 21 is distributed with the liner 2 are its distributary division, and the distributary division both sides of liner 2 are equipped with
Corresponding reinforcing gusset 3, and the two outer side edges for strengthening gusset 3 are connected to 1 inner wall of barrel shell of 11 both sides of fluid inlet
On；It is in phase that described two corresponding with distributary division, which are strengthened gusset 3 to separate 1 inner cavity of barrel shell between fluid inlet 11 and shunting zone,
To independent passage, and this passage portion space of barrel shell 1 enter as heat transferring medium after dispersion area, heat transferring medium is from fluid
Import 11 enters in barrel shell 1 and enters liner 2 by corresponding some tap holes 21 in dispersion area, so as to avoid heat transferring medium
Heat exchanger tube directly is washed away, the heat exchanger tube in 2 whole shell side of liner is simultaneously participated in heat exchange process to improve heat exchange efficiency.
The sidewall sections that explosion relief 22 is distributed with the liner 2 are its relief part, and the relief part both sides of liner 2 are equipped with
Corresponding reinforcing gusset 3, and the two outer side edges for strengthening gusset 3 are connected to 1 inner wall of barrel shell of 12 both sides of fluid outlet
On；Described two corresponding with relief part are strengthened the symmetric support structure that gusset 3 strengthens gusset 3 as distributary division both sides, can be carried
High overall stability and structural strength；The two strengthen gusset 3 by the barrel shell 1 between relief part and fluid outlet 12 at the same time
It is in another relatively independent passage that chamber, which separates, and this passage portion connection liner 2 and fluid outlet 12 of barrel shell 1, make by
Barrel shell 1 can quickly be flowed out by changing hot medium, avoid the erosion control baffle in existing heat exchanger structure, simplify mechanism setting.
The reinforcing gusset 3 is axially disposed and the interior outer side edges of reinforcing gusset 3 are respectively welded at 2 outer wall of liner and barrel shell
On 1 inner wall；Relative position of the liner 2 in barrel shell 1 can be accurately positioned by symmetrically arranged reinforcing gusset 3, the present invention preferably adopts
With two groups of reinforcing gussets 3 for corresponding to shunting zone and release of pressure area respectively, the stability and intensity of structure can be improved, and is conducive to assemble
The convenience of welding.
Some through holes 32 are provided with the reinforcing gusset 3, the through hole 32 is used to connect the cylinder for strengthening 3 both sides of gusset
1 inner space of shell, avoids the inner space for producing barrel shell 1 and liner 2 from pressure differential occur, improves structural stability and rationally
Property.
The inboard side for strengthening gusset 3 is equipped with the connection sheet 31 with its L-shaped integrative-structure, the side wall of liner 2
It is equipped with some and strengthens the one-to-one weld seam mouth 23 of gusset 3, connection sheet 31 is consolidated with 2 sidewall weld of liner at weld seam mouth 23
It is fixed；Reinforcing gusset 3 can be welded on by currently preferred reinforcing gusset 3 first using integral bending and molding structure in processing
On 1 inner wall of barrel shell, then liner 2 is installed again and welded by sealing mouth 23, avoid between liner 2 and barrel shell 1 space compared with
Difficulty of processing caused by small, to improve efficiency of assembling, further improves space accounting and heat exchange of the liner 2 in barrel shell 1
Area.
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
21 flux summation；The liner 2 is by the explosion relief 22 of bigger flux so that between fluid inlet 11 and fluid outlet 12
Flow resistance is reduced, improves the efficiency of heat transferring medium flowing in liner 2 and barrel shell 1, avoids the generation of turbulent flow, simplifies structure
Improve heat transfer effect.
The above is only the better embodiment of the present invention, therefore all constructions according to described in present patent application scope,
