Abstract
The utility model discloses an anti-vibration support plate for tube bundles. The anti-vibration support plate comprises a shell pass material inlet or outlet and a baffle plate. A support plate is arranged below the shell pass material inlet or outlet, a notch is arranged on the support plate, and the direction of the notch is opposite to the direction of the adjacent baffle plate. The anti-vibration support plate has the advantages that the support plate is arranged below the shell pass material inlet or outlet, the notch is arranged on the support plate, and the direction of the notch is opposite to the direction of the adjacent baffle plate, so that the shell pass material inlet or outlet is supported by the support plate below, non support span at the inlet or outlet can be reduced, and vibration is further reduced.
Description
Technical field
The utility model relates to a kind of gripper shoe, is specifically related to a kind of tube bank vibration proof gripper shoe.
Background technology
The existing century-old history of the appearance of shell-and-tube heat exchanger is one of most widely used unit, accounts for more than 50% of the whole heat exchanger output of China.Common shell-and-tube heat exchanger adopts segmental baffle, and deflection plate and heat exchanger tube are arranged vertically, and have flow dead, and heat exchange efficiency is difficult to improve; Fluid cross is skimmed over heat exchanger tube, restrains easy vibration-generating, causes the loosening or heat exchanger tube fracture in heat exchanger tube and tube sheet junction, causes heat exchanger failure, and the vibration problem in the major diameter heat exchanger is even more serious.There is the sixties in 20th century scholar to propose the structural shape of helical baffles, but because manufacture difficulty is larger, fails to realize suitability for industrialized production always.Czech scientists in 1986 have obtained the patent of helical baffles, and ABB AB had realized the industrialization manufacturing in 1994, had obtained application in western countries such as America and Europes.
Traditional shell-and-tube heat exchanger adopts single segmental baffle to support, and shell-side fluid easily produces flow blind angle, and heat transfer area can't be fully utilized, thereby the shell side heat transfer coefficient is low, easy fouling, fluid resistance are large.When fluid cross flows through tube bank, also may make pipe produce induced vibration, destroy the reliability that pipe and tube sheet thereof connect.
Double segmental baffle is divided into two strands of parallel beams at the heat exchanger shell-side with fluid, lateral flow length is roughly half of single segmental baffle with same breach, compare with the single segmental baffle with identical baffle(s) spacing and breach, the pressure drop of bouble-bow deflection plate is the 30%-50% of comparable equipment analog value.The shell-side fluid cross-current is crossed tube bank, and the heat exchanger tube vibration-generating is in shell-and-tube heat exchanger, in shell side material inlet or exit, because support is not set, so easily produce the problem of tube bundle vibration.
The utility model content
The purpose of this utility model is to propose a kind of tube bank vibration proof gripper shoe, and of the prior art no-support spaning distance is larger in shell side material inlet or exit to solve, and easily produces the problem of tube bundle vibration.
For reaching this purpose, the utility model by the following technical solutions:
A kind of tube bank vibration proof gripper shoe comprises shell side material inlet or outlet, deflection plate, under shell side material inlet or outlet, gripper shoe is set, and is provided with breach on described gripper shoe, and described breach direction is opposite with adjacent baffle.
Preferably, described breach can be arranged on the side of gripper shoe.
Preferably, described breach also can be arranged on the centre of gripper shoe.
The beneficial effects of the utility model are: owing under shell side material inlet or outlet, gripper shoe being set, be provided with breach on described gripper shoe, described breach direction is opposite with adjacent baffle, so, the support of gripper shoe is arranged under shell side material inlet or outlet, can reduce the import and export no-support spaning distance, reduce vibration.
Description of drawings
A kind of breach of restraining the vibration proof gripper shoe that Fig. 1 provides for the utility model specific embodiment 1 is arranged on the structural representation of a side;
Structural representation in the middle of a kind of breach of restraining the vibration proof gripper shoe that Fig. 2 provides for the utility model specific embodiment 1 is arranged on;
A kind of breach of restraining the vibration proof gripper shoe that Fig. 3 provides for the utility model specific embodiment 1 is arranged on the structural representation of both sides.
In figure:
1, gripper shoe; 2, breach.
The specific embodiment
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment, as shown in Figure 1 to Figure 3, a kind of tube bank vibration proof gripper shoe, comprise shell side material inlet or outlet, deflection plate, under shell side material inlet or outlet, gripper shoe 1 is set, be provided with breach 2 on described gripper shoe 1, when deflection plate is single bow plate, the structure of gripper shoe 1 as shown in Figure 1, breach 2 directions are opposite with adjacent baffle preferably, and breach 2 can be arranged on a side of gripper shoe 1; When deflection plate was the bouble-bow plate, the structure of gripper shoe 1 was Fig. 2 or shown in Figure 3, and breach 2 directions are opposite with adjacent baffle, and described breach 2 can be arranged on the centre of gripper shoe 1.Above-mentioned gripper shoe 1 provides effective twelve Earthly Branches support for the shell side import and export, has effectively avoided bundle vibration.
Above embodiment has just set forth basic principle of the present utility model and characteristic; the utility model is not limited by above-described embodiment; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (3)
1. a tube bank vibration proof gripper shoe, comprise shell side material inlet or outlet, deflection plate, and it is characterized in that: under shell side material inlet or outlet, gripper shoe is set, is provided with breach on described gripper shoe, described breach direction is opposite with adjacent baffle.
2. a kind of tube bank vibration proof gripper shoe as claimed in claim 1, it is characterized in that: described breach can be arranged on the side of gripper shoe.
