Description

Vibration-proof tube type heat exchanger

Technical Field

The utility model relates to a heat exchange equipment field particularly, relates to a shell and tube heat exchanger of antivibration.

Background

The shell and tube heat exchanger is a heat exchanger which is most widely applied in chemical production at present and mainly comprises a shell, a tube plate, a heat exchange tube, an end enclosure, a baffling baffle and the like. When heat exchange is carried out, a fluid enters from the connecting pipe of the end socket and flows out from the outlet pipe at the other end of the end socket, which is called a pipe pass; the other fluid enters from a connecting pipe of the shell and flows out from the other connecting pipe on the shell, and the other fluid is called shell side.

The service life of the heat exchanger directly influences the manufacturing cost of the whole device, and the heat exchange tube is one of the most important parts of the heat exchanger and plays a main role in heat exchange. The vibration of the heat exchange tube can cause the welded joint of the heat exchange tube and the tube plate to generate cracks so as to cause leakage, and the vibration of the heat exchange tube can also cause the collision between the heat exchange tube and the baffle hole so as to damage the heat exchange tube so as to cause leakage. Therefore, the vibration problem of the heat exchange tube has a great influence on the service life of the whole heat exchanger. The vibration problem of the heat exchange tube is solved, and the service life of the tube bundle can be prolonged.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a main aim at provides an anti-vibration's shell and tube heat exchanger to the vibration problem of heat exchange tube.

In order to realize the above object, the utility model discloses a shell and tube heat exchanger of antivibration, including tube sheet, heat exchange tube, head and baffling board, still include the antivibration ring, the antivibration ring cover is on the outer wall of partial heat exchange tube, and the heat exchange tube that the cover has the antivibration ring is called I class pipe, and the heat exchange tube that does not have the antivibration ring is called II class pipe, and I class pipe contacts through antivibration ring and II class pipe, contactless between II class pipe and the II class pipe.

Preferably, the material of the vibration-proof ring is the same as that of the baffle plate.

Preferably, the thickness of the anti-vibration ring is the same as the distance between the class i and class ii tubes.

Preferably, the anti-vibration rings on two adjacent class i tubes are staggered.

Preferably, the class i tube is sleeved at both ends with anti-vibration rings.

The utility model discloses following beneficial effect has: the utility model discloses a cover is established the antivibration ring and is made spaced apart between the heat exchange tube on the heat exchange tube, makes the antivibration ring lose the vibration space to reach the purpose of antivibration.

Drawings

Fig. 1 is a schematic view of the lateral distribution of the anti-vibration ring;

fig. 2 is a schematic view of the longitudinal distribution of the anti-vibration rings;

wherein the figures include the following reference numerals: 1. a heat exchange pipe; 2. an anti-vibration ring.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

The utility model discloses a tubular heat exchanger of antivibration, increased antivibration ring 2 on the basis of conventional structure-tube sheet, heat exchange tube 1, head and baffling board, the antivibration ring overlaps on the outer wall of partial heat exchange tube.

The distribution rule of the vibration-proof rings is as follows: the heat exchange tube sleeved with the anti-vibration ring is called a type I tube, the heat exchange tube not sleeved with the anti-vibration ring is called a type II tube, the type I tube is contacted with the type II tube through the anti-vibration ring after the anti-vibration ring is sleeved on the heat exchange tube, and the type II tube is not contacted with the type II tube. This effect is achieved by spacing the class i and class ii tubes in columns as shown in figure 1.

The both ends of I type pipe all overlap there is the antivibration ring, and the thickness of antivibration ring is the same with the distance between I type pipe and the II type pipe, makes the heat exchange tube lose the vibration space through the antivibration ring to reach the purpose of antivibration.

In order not to influence the heat exchange effect, the vibration-proof ring is made of the same metal material as the baffle plate.

When the heat exchange tube is assembled, the anti-vibration rings can be arranged in a staggered mode in order to avoid the influence of fluid blockage on the heat exchange effect. As shown in fig. 2, the anti-vibration rings on two adjacent class i tubes are distributed in a staggered manner and are not on the same plane.

The heat exchange tube vibration problem caused by fluid evaporation or boiling is solved, and the heat exchange tube vibration device can be widely applied to evaporators, reboilers and the like.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
