Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to an anti-impact device for an ultra-large inlet pipe of a heat exchanger. Background Technology

[0002] Currently, in the field of heat exchangers, especially in large-scale industrial applications, efficient heat exchanger design is crucial for improving energy efficiency and reducing equipment operating costs.

[0003] In existing heat exchangers, when fluid from the oversized nozzle enters the shell side at high speed, it often causes severe erosion of the tube sheet and tube bundle, resulting in a shortened service life. Therefore, in order to advance industry technology, better protect the tube sheet and tube bundle, and improve core technology competitiveness, this application proposes a new implementation scheme that differs from the structure of the oversized nozzle inlet of heat exchangers in the prior art. Utility Model Content

[0004] The purpose of this invention is to solve the problem that when fluid from an oversized nozzle enters the shell side at high speed during the operation of existing heat exchangers, it often causes severe erosion of the tube sheet and tube bundle, leading to a shortened service life of the equipment. Therefore, this invention proposes an anti-erosion device for the inlet of an oversized nozzle in a heat exchanger.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An anti-impact device for an extra-large inlet pipe of a heat exchanger includes an anti-impact assembly. The anti-impact assembly includes a central support plate and two peripheral support plates. A central anti-impact plate is fixedly connected between the central support plate and the peripheral support plates. Multiple first-side anti-impact plates and multiple second-side anti-impact plates are fixedly connected between the central support plate and the peripheral support plates.

[0007] Furthermore, the angle between the central support plate and the outer support plate and the central anti-impact plate, the first side anti-impact plate and the second side anti-impact plate is degrees.

[0008] Furthermore, the central anti-impact plate, the first side anti-impact plate, and the second side anti-impact plate are made of flat steel strips.

[0009] Furthermore, the central anti-impact plate has a V-shaped structure.

[0010] Furthermore, one end of the first side anti-impact plate and the second side anti-impact plate is bent into an arc shape.

[0011] Furthermore, two connecting plates are fixedly connected to both ends of the central support plate and the two outer support plates.

[0012] Furthermore, an outer reinforcing plate is fixedly connected to the bottom of the outer support plate, and multiple inner reinforcing plates are fixedly connected between the two outer reinforcing plates. The top of the inner reinforcing plate is fixedly connected to the bottom of the central support plate, and multiple openings are provided on the inner reinforcing plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By allowing fluid to pass through the gaps between the central anti-impact plate, the first side anti-impact plate, and the second side anti-impact plate, the fluid impact force is dispersed, thus preventing erosion of the tube sheet and tube bundle and extending the service life of the equipment.

[0015] 2. The central support plate is supported by outer and inner reinforcing plates, thereby improving the stability of the anti-impact device. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1

[0024] Reference Figures 1-3An anti-impact device for an ultra-large inlet pipe of a heat exchanger includes an anti-impact component 1. The anti-impact component 1 includes a central support plate 101 and two peripheral support plates 102. A central anti-impact plate 103 is welded between the central support plate 101 and the peripheral support plates 102. A plurality of first-side anti-impact plates 104 and a plurality of second-side anti-impact plates 105 are welded between the central support plate 101 and the peripheral support plates 102. Fluid passes through the gaps between the central anti-impact plate 103, the first-side anti-impact plates 104, and the second-side anti-impact plates 105, thereby dispersing the fluid impact force.

[0025] The angle between the central support plate 101 and the outer support plate 102 and the central anti-impact plate 103, the first side anti-impact plate 104 and the second side anti-impact plate 105 is 45 degrees. The central anti-impact plate 103, the first side anti-impact plate 104 and the second side anti-impact plate 105 are made of flat steel strips. The central anti-impact plate 103 has a V-shaped structure. One end of the first side anti-impact plate 104 and the second side anti-impact plate 105 is bent into an arc shape. The spacing between the central anti-impact plate 103, the first side anti-impact plate 104 and the second side anti-impact plate 105 is designed to be 50mm-100mm, so as to adapt to the fluid velocity and pressure under different working conditions.

[0026] The working principle of this embodiment is as follows: When in use, firstly, the anti-impact device is installed at the inlet of the heat exchanger's extra-large pipe. Then, the fluid passes through the gap between the central anti-impact plate 103, the first side anti-impact plate 104, and the second side anti-impact plate 105, thereby dispersing the fluid impact force and ensuring uniform fluid distribution.

[0028] Reference Figures 4-5 An anti-impact device for an extra-large inlet pipe of a heat exchanger includes a central support plate 101 and two connecting plates 2 welded to both ends of two outer support plates 102. The connecting plates 2 connect the central support plate 101 and the outer support plates 102 into one unit, thereby improving the robustness of the anti-impact device. An outer reinforcing plate 3 is welded to the bottom of the outer support plate 102, and multiple inner reinforcing plates 4 are welded between the two outer reinforcing plates 3. The top of the inner reinforcing plate 4 is fixedly connected to the bottom of the central support plate 101. The outer reinforcing plates 3 and the inner reinforcing plates 4 support the central support plate 101, thereby improving the stability of the anti-impact device. Multiple openings 5 ​​are provided on the inner reinforcing plate 4 to facilitate the passage of fluid.

[0029] The working principle of this embodiment is as follows: When in use, the connecting plate 2 connects the central support plate 101 and the outer support plate 102 into one unit, thereby improving the robustness of the anti-impact device. Then, the outer reinforcing plate 3 and the inner reinforcing plate 4 support the central support plate 101, thereby improving the stability of the anti-impact device.
