Abstract
The invention discloses an impingement plate structure of a heat exchanger. The impingement plate structure comprises an inlet joint pipe, an impingement plate and ribbed plates; the lower end of the inlet joint pipe is welded on a shell of the heat exchanger; the impingement plate is fixed right below the inlet joint pipe through the two ribbed plates at the lower end of the inlet joint pipe and is located above a heat-exchanging pipe; the impingement plate has a V-shaped cross section, and two ends of the impingement extend to form convex plates; each ribbed plate has an L-shaped cross section, and comprises a long edge and a short edge; the upper end face of each ribbed plate is welded on the inner side wall of the shell, and the long edge of each ribbed plate is vertical to the shell; and the impingement plate is located above the short edge of each ribbed plate, and the bottom face of each convex plate of the impingement plate is welded on the upper surface of the short edge of each ribbed plate. According to the impingement plate structure of the heat exchanger in the scheme disclosed by the invention, the impingement plate structure has a simple structure and can be used for effectively preventing the impingement plate from falling off in a heat exchanger operation process, and thus, the normal operation of the heat exchanger is ensured.
Description
Technical field
The present invention relates to a kind of auxiliary element of heat exchanger, the impingement baffle structure on especially a kind of heat exchanger belongs to heat exchanger servicing unit technical field.
Background technology
Shell side entrance sleeve place in heat exchanger all is fixed with impingement baffle.This is because in heat exchanger, and the density of gas and liquid phase are than much little, and flow velocity was very big when gas got into heat exchanger, if impingement baffle protection is not set, gas is the impingement heat transfer pipe directly, causes the heat exchanger tube sharp pounding.The vibrations of heat exchanger tube not only can cause between the adjacent heat exchange tubes, and the perhaps collision between heat exchanger tube and the housing is worn heat exchanger tube and housing and ftractures, and seriously, heat exchanger tube also can be severed.Because of vibrations are ftractureed, phenomenon of rupture, in the existing heat exchanger, all be provided with impingement baffle structure (shown in accompanying drawing 1) for fear of heat exchanger tube.Impingement baffle 20 of the prior art is a tabular; Two gussets 30 lay respectively at the both sides of impingement baffle 20 tops, and an end welding heat exchanger housing 40 of gusset 30, other end welding impingement baffle 20; Impingement baffle 20 be positioned at inlet connection 50 under, be positioned at the top of heat exchanger tube 10.Because impingement baffle of the prior art all is the plane, and is normally in service at heat exchanger, because in the inlet connection; Obscission takes place in the compression shock of medium, impingement baffle often, and the impingement baffle that comes off not only can not be protected heat exchanger tube; And the impingement baffle that comes off also can pound the Lou heat exchanger tube of the last layer of heat exchanger,, cause the shell side and the short circuit of tube side medium of heat exchanger; Make heat exchanger tube normally not move, seriously, heat exchanger tube also might just have been scrapped.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of impingement baffle that prevents and come off, guaranteed the heat exchanger impingement baffle structure of the normal operation of heat exchanger.
Technical solution of the present invention is achieved in that a kind of heat exchanger impingement baffle structure, comprises inlet connection, impingement baffle and gusset; The lower end of said inlet connection is welded on the housing of heat exchanger; Two gussets of said impingement baffle through the inlet connection lower end, be fixed on inlet connection under, and impingement baffle is positioned at the top of heat exchanger tube; The cross section of said impingement baffle is an inverted V-shaped, and the two ends of impingement baffle are extended with flange; The cross section of said gusset is L shaped, and it comprises a long limit and a minor face; The upper surface of said gusset is welded on the housing madial wall, and the long limit of gusset is perpendicular to housing; Said impingement baffle is positioned at the minor face top of gusset, and the bottom surface of impingement baffle flange is welded on the upper surface of gusset minor face.
Preferably, also be welded with a plurality of fixing ribs above the said impingement baffle; The top edge of said fixing ribs is welded on the inwall of inlet connection, and lower limb is welded on the upper surface of impingement baffle; Said fixing ribs is fixed on the both sides on impingement baffle summit in uniform way.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Heat exchanger impingement baffle structure of the present invention, it makes gusset into L shaped shape, and impingement baffle is made as inverted V-shaped; And the both sides of impingement baffle are extended with flange; Through the welding of minor face and impingement baffle flange, with impingement baffle be fixed on firmly inlet connection under, not only do not influence the circulation area situation of medium; Also improve simultaneously the rigidity of impingement baffle anti-impact force, greatly reduced the jitter amplitude of impingement baffle; In addition, the fixing ribs of above impingement baffle, welding has not only prevented impingement baffle shake up and down along with the variation of pressure, and the stress that has also alleviated gusset and impingement baffle, housing weld is simultaneously greatly concentrated, and has avoided splitting of weld seam.The present invention program's heat exchanger impingement baffle structure, it is simple in structure, has prevented effectively in the heat exchanger running, and coming off of impingement baffle guaranteed the normal operation of heat exchanger.
