Abstract
The utility model relates to a scour-preventing device used for a heat exchange tube bundle of a heat exchanger. The scour-preventing device used for the heat exchange tube bundle of the heat exchanger includes scour-preventing pipes with hollow structures. The scour-preventing pipes sleeve on the heat exchange tubes of the heat exchange tube bundle and is fixed on a baffle plate of the heat exchange device together with the heat exchange tubes. Gaps are arranged between the adjacent scour-preventing tubes. The scour-preventing tubes are arranged in at least two rows, so that a scour-preventing effect is enhanced. The scour-preventing device is arranged on the heat exchange tube in a medium entrance. Compared with a scour-preventing board in the prior art, the scour-preventing device used for the heat exchange tube bundle of the heat exchanger avoids scour-preventing board displacement due to connection part damages and fluid distribution becomes uniform. Compared with a scour-preventing rod, the scour-preventing device can be sleeved on the heat exchange tubes directly, so that space occupancy is reduced, equipment size is reduced and cost is lowered. Besides, by adopting the scour-preventing device, the number of the heat exchange tubes installed in the heat exchanger can be increased and heat exchange area can be enlarged. The scour-preventing device is simple in structure, reasonable in design, free of external welding, good in scour preventing effect and low in equipment cost.
Description
Technical field
The utility model belongs to heat transfer technology field, specifically, relates to a kind of heat exchanger heat-exchanging tube bundle checking motion.
Background technology
Existing exchange tube bundle anti-impact is many prevents that with impingement baffle fluid from directly washing away heat exchanger tube and causing heat exchanger tube vibration unstability and corrosion.Common impingement baffle shape mostly is in-line, inverted V-shaped, semicircle or circular arc; It is placed in place, medium inlet, is fixedly connected with heat exchanger tube.It is poor that impingement baffle is shouldered impulsive force, fluid in porch general pressure oscillation frequent, easily cause impingement baffle vibration amplitude value larger, add liquid corrosion reason, affixed position is easily damaged, and then directly cause impingement baffle displacement, and even cause the damaged leakage of heat exchanger tube, make impingement baffle lose erosion control effect.On the other hand, add after impingement baffle, fluid is concentrated in impingement baffle two ends and enters tube bank district, and fluid skewness, still can exchange heat pipe and impact destruction, and it is large that pressure drop becomes.
Patent CN201020506710.9 provides a kind of heat exchange tube bundle anti-impact device of shell, and its structure is, two-layer solid anti-jumper bar is set between heat exchanger tube and fluid intake, and anti-jumper bar is fixed with gripper shoe or deflection plate.It has solved the fluid problem pockety that impingement baffle causes, but anti-jumper bar is between heat exchanger tube and fluid intake, the place of solid hopkinson bar is installed and cannot places heat exchanger tube, will certainly increase heat exchanger volume, improve equipment cost, and, once the connecting portion of anti-jumper bar and deflection plate or gripper shoe is loosening, to cause anti-jumper bar to come off, erosion control function weakens, and even damages heat exchanger tube.
Utility model content
For solving the problems of the technologies described above, this use is novel has proposed a kind of difficult drop-off, equipment volume is little and cost is low heat exchanger heat-exchanging tube bundle checking motion.
The technical solution of the utility model is: a kind of heat exchanger heat-exchanging tube bundle checking motion, it comprises anti-washing pipe, described anti-washing pipe is hollow structure, it is set on the heat exchanger tube of described heat-exchanging tube bundle, and be fixed on together with heat exchanger tube on the deflection plate of described heat exchanger, between adjacent anti-washing pipe, be provided with gap.
It is mobile that shuttling back and forth of medium is convenient in the setting in described gap, and the velocity of medium after anti-washing pipe slows down, and the impulsive force of exchange heat pipe diminishes, and can play against shock and corrosion-resisting function.
Described anti-washing pipe at least arranges two rows, to strengthen erosion control effect.
Above-mentioned checking motion is arranged on the heat exchanger tube at place, medium inlet.The quantity of the anti-washing pipe of horizontally set meets the following conditions: the width of the horizontally set of anti-washing pipe is greater than the medium inlet diameter of described heat exchanger.
Described erosion control length of tube equals the spacing between plate A and plate B, and erosion control length of tube is greater than the medium inlet diameter of described heat exchanger.Described plate A is tube sheet or deflection plate, and plate B is deflection plate.The object that erosion control length of tube arranges is like this in order to play better erosion control effect, if the length of anti-washing pipe is less than the spacing between the spacing between plate A and plate B, or be less than the diameter at medium inlet place, or the width of the horizontally set of anti-washing pipe is greater than the medium inlet diameter of described heat exchanger, can make being directly exposed in fluid media (medium) of part heat exchanger tube, lose erosion control effect.
The beneficial effects of the utility model are:
1,, compared to the impingement baffle of prior art, avoided connecting portion to damage and caused impingement baffle displacement, even fluid distribution; Compared to anti-jumper bar, be directly set on heat exchanger tube, saved space, reduce equipment volume, reduce costs, and the heat exchanger of same volume, the heat exchanger tube quantity that the utility model is installed is many, and heat exchange area increases;
2, simple in structure, reasonable in design, without welding separately checking motion, erosion control is effective, equipment cost is low.
