Abstract
The invention relates to an anti-scouring structure of a heat exchanger and belongs to the technical field of heat exchanger. The anti-scouring structure of the heat exchanger comprises arc-shaped supporting plates, heat exchange tubes and anti-scouring plates. The anti-scouring plates are arranged between the heat exchange tubes and a shell side inlet, and gaps are formed between the anti-scouring plates. Three arc-shaped supporting plates are connected between the heat exchange tubes, and the three arc-shaped supporting plates are distributed in the tube body length directions of the heat exchange tubes. The anti-scouring plates arranged at the lower ends of the multiple heat exchange tubes are mutually connected on the three arc-shaped supporting plates in a welded mode. According to the anti-scouring structure of the heat exchanger, the semicircular anti-scouring plates are adopted and wrapped outside the heat exchange tubes which are subjected to scouring corrosion, so that the heat exchange tubes are prevented from being scoured directly by a medium entering from the sell side inlet. The anti-scouring plates arranged at the lower ends of the heat exchange tubes are arranged independently, and an one-piece form is not used; the gaps are formed between the anti-scouring plates, so that it is not needed to consider the flow area of a connecting tube, the quantity of the heat exchange tubes can be increased as much as possible at design time, the quantity of the distributed tubes can be increased, and the heat exchange area of the heat exchanger is increased.
Description
Technical field
The present invention relates to a kind of heat exchanger anti-washing structure, belong 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 object of the invention is to overcome above-mentioned weak point, thus a kind of heat exchanger anti-washing structure is provided, decrease the vibrations of tube bank, add the heat exchange area of heat exchanger.Decrease the resistance drop of tube bank.
According to technical scheme provided by the invention, 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 present invention has the following advantages:
Structure of the present invention 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.

Fig. 2 is front view of the present invention.
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 present invention below:
As shown in Figure 1 and 2, the present invention 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 present invention 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.
