Abstract

The utility model belongs to the structure improvement of a heat exchanger, a heat exchanger with a vibration damping deflecting plate, which comprises a tube box, a tube pass connection tube, a shell pass connection tube, a cylinder, heat exchange tubes, an end socket, a vibration damping pad, and a deflecting plate. The utility model has the essential structure that the deflecting plate is a deflecting plate which is provided with the vibration damping pad. The utility model has the advantages that the vibration of the heat exchanger is reduced, noise is reduced, the service life of the heat exchanger is prolonged, etc.

Description

A kind of heat exchanger with vibration damping deflection plate

The utility model relates to the improvement of baffle arrangement in the heat exchanger.

In shell-and-tube heat exchanger and modified (as corrugated tube heat exchanger) heat exchanger thereof, owing to have-tube bank of determined number is installed side by side, deflection plate is installed perpendicular to heat exchanger tube and be rigid the contact with heat exchanger tube, thereby when the shell-side fluid cross-current out-of-date, Chang Rongyi evokes the vibration between heat exchanger tube and the deflection plate, in addition send noise more than 100 decibels, cause the heat exchanger tube fatigue damage, consequences such as wearing and tearing cracking or cut-out.

The purpose of this utility model just is to provide a kind of heat exchanger that heat exchanger tube vibrates, improves service life that reduces.

The purpose of this utility model is achieved in that on the deflection plate of deflection plate in heat exchanger and heat exchanger tube touching position cushion blocking is set, realizes the utility model above-mentioned purpose with this.

Because the utility model is to be provided with the deflection plate with cushion blocking, therefore realize that heat exchanger tube and the flexibility between the deflection plate contact, can reduce the vibration of heat exchanger, the service life of reduce noise, having improved heat exchanger.

This device can be under water, steam and partial solvent below 300 ℃ operate as normal.

Fig. 2 is the user mode figure of bellows for the utility model heat exchanger tube;

Fig. 3 is the user mode figure of straight tube for the utility model heat exchanger tube;

Fig. 4 is a cushion blocking schematic diagram of the present utility model;

Fig. 5 is A-A cutaway view of Fig. 4.

Below in conjunction with accompanying drawing concrete structure of the present utility model is done to describe in detail:

The utility model comprises that bobbin carriage (1), tube side are taken over (2), shell side is taken over (3), cushion blocking (4), cylindrical shell (5), heat exchanger tube (6), end socket (7), deflection plate (8); Deflection plate (8) is the deflection plate (8) that has cushion blocking.

For improve effectiveness in vibration suppression and be convenient to install, cushion blocking (4) on the deflection plate (8) can be made into a side and has the cushion blocking (4) that otch (10) and outside have groove (9).

Cushion blocking (4) on the utility model deflection plate (8) can be made into circle, as shown in Figure 4, also can be made into non-circular.The material of cushion blocking (4) can be a graphite rubber, also other rubber-like flexible material such as nylon.

Deflection plate of the present utility model (8) can be installed and deposit in the corrugated tube heat exchanger, as shown in Figure 2, also can be installed in the shell-and-tube heat exchanger, as shown in Figure 3.

Claims

1. heat exchanger with vibration damping deflection plate, comprise that bobbin carriage (1), tube side are taken over (2), shell side is taken over (3), cushion blocking (4), cylindrical shell (5), heat exchanger tube (6), end socket (7), deflection plate (8), it is characterized in that deflection plate (8) is for having the deflection plate (8) of cushion blocking (4).

2. heat exchanger according to claim 1 is characterized in that cushion blocking (4) on the heat exchanger deflection plate (8) is that a side has the cushion blocking (4) that otch (10) and outside have groove (9).
