Strengthen the turbulivity of fluid, reduce the vibration of heat exchanger, solve the wear problem between corrugated tube bundle and deflection plate.
In order to achieve the above object, the present invention is realized using following technical scheme：
A kind of deflection element of shell-and-tube heat exchanger, including square hole baffle plate and sleeve pipe fixed plate；The square hole baffle plate edge is horizontal
To being arranged in the housing of shell-and-tube heat exchanger, for fixing bellows；Square hole baffle plate is the circle being engaged with housing inner diameter
Orifice plate, is uniformly distributed multiple square through holes thereon；Sleeve pipe fixed plate is embedded in square through hole, inner side and the crest section phase of bellows
Cut.
Described sleeve pipe fixed plate is the square frame-shaped structure being engaged with square through hole, one of right angle of square frame-shaped structure
Both sides cut off 1/4 length of side respectively.
Described sleeve pipe fixed plate is embedded in shape through hole, is welded and fixed with square baffle plate.
The thickness of described sleeve pipe fixed plate is 1~2 times of bellows pitch of waves.
Multiple sides are laterally set in a kind of method of work of the deflection element of shell-and-tube heat exchanger, shell-and-tube heat exchanger
Hole baffle plate, the longitudinally disposed heat-exchanging tube bundle being made up of multiple bellowss；The crest section of bellows passes through sleeve pipe fixed plate and square hole
Baffle plate is fixed；Bellows is made up of smooth straight, and centre is the crest section and trough section of multiple alternately connections, and two ends pass through straight tube
Section is connected with tube sheet；During heat exchange, shell-side fluid flows transversely through square hole baffle plate and sleeve pipe fixed plate, can remove flow dead；So
Accelerate outflow from the gap of sleeve pipe fixed plate and bellows afterwards, hit with adjacent corrugations pipe, strengthen the turbulence effects of fluid, beat
Fluid boundary layer in broken inner walls, improves overall heat-transfer effect；Fluid is avoided simultaneously and directly hits housing, reduces shell
The vibration of formula heat exchanger.
Compared with prior art, the beneficial effects of the invention are as follows：
1) square hole baffle plate is used, fluid can be avoided directly to hit housing, shell side resistance is effectively reduced, flowing is removed dead
Area, shell-and-tube heat exchanger is not likely to produce dirt and vibration；
2) sleeve pipe fixed plate is the square frame-shaped structure of unfilled corner, and it is fixed in the square through hole of square hole baffle plate, makes tube side knot
Structure is more stablized, and constitutes shell side turbulent element, strengthens the scrambling of flow of fluid, increases the circulating rate of fluid, improves
The surface coefficient of heat transfer of shell side side；
3) inner side of sleeve pipe fixed plate and bellows crest section are tangent, for fixing bellows, bellows is kept off with square hole
Plate can be coordinated with lossless, reduced the abrasion of bellows, simplified the installation of bellows, improve the stability of tube side structure；
4) shell-side fluid accelerates to flow out from the gap of bellows and sleeve pipe fixed plate, and shock is produced with adjacent corrugations pipe, breaks
The fluid boundary layer on tube wall is broken, overall heat-transfer effect is improved.
