Abstract
The utility model relates to a heat exchanger technical field, specifically speaking relate to a novel impingement baffle structure. The traditional scour protection will influence the installation of tube bank when shell side import and pull rod all are in same one side tube sheet direction, and the structure is for with medium shell side import syntropy, and the breach entering of medium from its I-shaped, and the impact force is strong, and the noise is big, and the scour protection ability is poor, and life is shorter relatively. A novel impingement baffle structure is characterized in that an impingement baffle is arranged perpendicular to a flange, and impingement notches are staggered with inlet ports of shell-side media in the flange; the impingement baffle is in a transverse structure, one end of the impingement baffle is connected to the tube plate, and the other end of the impingement baffle is connected to the baffle plate; the impingement baffle comprises impingement main plate and the gusset at both ends, and the impingement gap is located between the two gussets. The impingement plate staggers the inlet port, reducing impact force and noise. The two ends of the impingement baffle are respectively connected to the tube plate and the baffle plate, so that the transverse length is increased, the strength is increased, and the service life is prolonged. Effectively prevent that the protecting against shock plate from droing, do not influence the mounted position of tube bank.
Description
Technical Field
The utility model relates to a heat exchanger technical field, more specifically say and relate to a novel impingement baffle structure.
Background
The heat exchanger is a device for transferring part of heat of hot fluid to cold fluid, and is also called as a heat exchanger. The heat exchanger plays an important role in chemical industry, petroleum industry, power industry, food industry and other industrial production, can be used as a heater, a cooler, a condenser, an evaporator, a reboiler and the like in chemical industry production, and is widely applied. Impingement plates are an important auxiliary element in the design and manufacturing process of heat exchangers. The installation structure of the impingement plate will affect the process usage. The traditional impingement baffle (as shown in figures 1-3) affects the installation of the tube bundle when the shell pass inlet and the pull rod are both in the same tube plate direction, and the structure is in the same direction as the medium shell pass inlet, the medium enters from the I-shaped notch of the medium shell pass inlet, the impact force is strong, the noise is large, the impingement capacity is poor, and the service life is relatively short.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a novel impingement baffle structure that is rational in infrastructure, more firm to prior art not enough.
A novel impingement baffle structure comprises a tube plate, a flange, a baffle plate and an impingement baffle, wherein the impingement baffle is arranged perpendicular to the flange, and an impingement notch of the impingement baffle is staggered with an inlet of a shell side medium in the flange; the impingement baffle is in a transverse structure, one end of the impingement baffle is connected to the tube plate, and the other end of the impingement baffle is connected to the baffle plate; the anti-impact plate consists of an anti-impact main plate and rib plates at two ends, and the anti-impact gap is positioned between the two rib plates. The impingement plate staggers the inlet port, reducing impact force and noise. The two ends of the impingement baffle are respectively connected to the tube plate and the baffle plate, so that the transverse length is increased, the strength is increased, and the service life is prolonged. Effectively prevent that the protecting against shock plate from droing, do not influence the mounted position of tube bank.
As a further improvement and supplement to the above solution, the present invention further comprises the following additional technical features:
the periphery of the impingement baffle is provided with chamfers. The welding is convenient.
The scour protection mainboard and gusset welding form in the scour protection board. Reasonable structure and easy processing.
The scour protection mainboard be square leak-free plate-shaped structure. Further enhancing the shock resistance.
Use the utility model discloses following beneficial effect can be reached: use this practical impingement plate mounting structure just can satisfy shell side import and pull rod all in the installation demand in same one side tube sheet direction, adopt dull and stereotyped impingement plate promptly to two band steel gusset of assembly welding enable the impingement plate more firm on between impingement plate and tube sheet, also make shell side medium reduce with vibrations to the erosion of heat exchange tube, effectively protected the heat exchange tube. Prevent the impingement plate from falling and losing efficacy. The problem of the use defect of traditional impingement baffle is solved. Because the direct impact of the medium is avoided, the noise is reduced.

Detailed Description
The following detailed description of embodiments of the present invention will be made with reference to the accompanying drawings.
As shown in fig. 4-6, the present invention relates to a novel fender structure.
The novel impingement baffle structure described in this embodiment includes a tube plate 1, a flange 2, a baffle plate 3, and an impingement baffle 4. The impingement baffle 4 is positioned in the heat exchanger and is arranged perpendicular to the axis of the flange 2, and an impingement notch of the impingement baffle is staggered with an inlet of a shell-side medium in the flange 2; the impingement baffle 4 is in a transverse structure and is consistent with the direction of the heat exchange tube body, one end of the impingement baffle is fixedly connected to the tube plate 1, and the other end of the impingement baffle is fixedly connected to the baffle plate 3; and the impingement baffle 4 consists of an impingement main plate 42 and rib plates 41 at two ends, and an impingement gap is positioned between the two rib plates 41. The impingement plate 4, the tube plate 1 and the baffle plate 3 can be fixed by welding. The upper and lower distances between the impingement plate 4 and the inlet of the shell-side medium in the flange 2 are increased, and other related parts in the heat exchanger are not affected.
Furthermore, the periphery of the impingement plate 4 is provided with chamfers.
Furthermore, the impingement plate 4 is formed by welding an impingement main plate 42 and a rib plate 41.
Further, the anti-scouring main plate 42 is a square leak-proof plate-shaped structure.
The above is the preferred embodiment of the present invention, and the protection scope of the present invention is not limited, and the deformation and improvement made by the design idea of the present invention for those skilled in the art should be considered as the protection scope of the present invention.
