Abstract
The utility model relates to a heat exchanger scour protection structure belongs to heat exchanger technical field. It includes arch support board, heat exchange tube and impingement baffle, and every heat exchange tube and shell side are equipped with an impingement baffle between entering the mouth, are equipped with the clearance between every impingement baffle. Connect three arch support board between a plurality of heat exchange tubes, three arch support board along the pipe length direction distribution of heat exchange tube. The common welded connection of a plurality of impingement baffle of a plurality of heat exchange tube lower extremes is on three arch support board. The utility model discloses outside shell side entrance adoption semicircular impingement baffle parcel is receiving the heat exchange tube of the erosion -corrosion, avoid washing away the directness of heat exchange tube from the medium that the shell side entry got into. The equal independent setting of impingement baffle under each heat exchange tube is not massive form, and is gapped between each impingement baffle, may not use and consider the flow area who takes over, can increase the quantity of heat exchange tube as far as at the design time, can increase stringing quantity, has increased the heat transfer area of heat exchanger.
Description
Technical field
The utility model relates to a kind of heat exchanger anti-washing structure, belongs to technical field of heat exchangers.
Background technology
In prior art, in the design process of oil refining industry heat exchanger, because shell side medium normally has corrosive gas or the higher liquid of flow velocity.Therefore need to arrange anti-washing structure at the entrance of shell side, with the erosion corrosion avoiding shell side inlet medium to exchange heat pipe.Traditional anti-washing structure is the steel plate by monoblock, is fixed in the tube bank at shell side inlet center, utilizes impingement baffle to stop washing away of shell side medium exchange heat pipe.Consider that shell side inlet place will ensure the circulation area of taking over, impingement baffle and inner walls must leave certain space, namely can not arrange heat exchanger tube in this space.This certainly will decrease the heat exchange area of heat exchanger.Meanwhile, due to the relation of installing, the longer part in impingement baffle present position can not arrange deflection plate, easily causes the vibrations of this position heat exchanger tube.On the other hand due to the existence of impingement baffle, result in the change of pipe laying structure, thus add the resistance drop of tube bank.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thus provides a kind of heat exchanger anti-washing structure, decreases the vibrations of tube bank, adds the heat exchange area of heat exchanger.Decrease the resistance drop of tube bank.
According to the technical scheme that the utility model provides, heat exchanger anti-washing structure comprises arc support plate, heat exchanger tube and impingement baffle, it is characterized in that: shell side inlet upper end is provided with multiple heat exchanger tube, an impingement baffle is provided with between each heat exchanger tube and shell side inlet, be provided with gap between each heat exchanger tube and impingement baffle, between each impingement baffle, be provided with gap; Connect three arc support plates between multiple heat exchanger tube, three arc support plates are along the tube length directional spreding of heat exchanger tube; Multiple impingement baffles of multiple heat exchanger tube lower end are welded to connect jointly on three arc support plates; The front portion of described multiple impingement baffle, middle part and rear portion be connected to three before and after distribution arc support plate on.
Further, impingement baffle is semicircle.
Compared with the prior art the utility model has the following advantages:
The utility model structure is simple, compact, reasonable, outside the heat exchanger tube that shell side inlet place adopts semicircular impingement baffle to be wrapped in by erosion corrosion, avoids directly washing away of the medium exchange heat pipe entered from shell side inlet.Impingement baffle under each heat exchanger tube is all independently arranged, and is not the form of monoblock, has gap between each impingement baffle, the circulation area of taking over can be considered, the quantity of heat exchanger tube can be increased when designing as much as possible, stringing quantity can be increased, add the heat exchange area of heat exchanger.Before anti-washing pipe, postmedian adopts arc support plate to fix, and the distance between arc support plate can adjust, thus changes by the intrinsic frequency of washing away position heat exchanger tube, reduces the vibration of this position heat exchanger tube.Impingement baffle, owing to adopting Pork-pieces semi-circular plate, can not change original cloth form of tubes, thus reduce the resistance drop of tube bank.

Description of reference numerals: 1-arc support plate, 2-heat exchanger tube, 3-impingement baffle, 4-shell side inlet.
Detailed description of the invention
Embodiment in is by reference to the accompanying drawings further described by the utility model below:
As shown in Figure 1 and 2, the utility model mainly comprises arc support plate 1, heat exchanger tube 2 and impingement baffle 3, shell side inlet 4 upper end is provided with multiple heat exchanger tube 2, a semicircular impingement baffle 3 is provided with between each heat exchanger tube 2 and shell side inlet 4, be provided with gap between each heat exchanger tube 2 and impingement baffle 3, between each impingement baffle 3, be provided with gap.
The tube length directional spreding of three arc support plates, 1, three arc support plates 1 along heat exchanger tube 2 is connected between multiple heat exchanger tube 2.
Multiple impingement baffles 3 of multiple heat exchanger tube 2 lower end are welded to connect jointly on three arc support plates 1.The front portion of described multiple impingement baffle 3, middle part and rear portion be connected to three before and after distribution arc support plate 1 on.
Outside the heat exchanger tube that the utility model adopts semicircular impingement baffle to be wrapped in by erosion corrosion at shell side inlet place, avoid directly washing away of the medium exchange heat pipe entered from shell side inlet.Impingement baffle under each heat exchanger tube is all independently arranged, and is not the form of monoblock, has gap between each impingement baffle, the circulation area of taking over can be considered, the quantity of heat exchanger tube can be increased when designing as much as possible, stringing quantity can be increased, add the heat exchange area of heat exchanger.Before anti-washing pipe, postmedian adopts arc support plate to fix, and the distance between arc support plate can adjust, thus changes by the intrinsic frequency of washing away position heat exchanger tube, reduces the vibration of this position heat exchanger tube.Impingement baffle, owing to adopting Pork-pieces semi-circular plate, can not change original cloth form of tubes, thus reduce the resistance drop of tube bank.
