AI Technical Summary

Technical Problem

During operation, the shell and tube heat exchanger is subjected to frequent collisions between the pipe and the passage holes on the baffle plate due to vibration of the fluid, causing heavy wear and noise.

Method used

A pipe support structure for shell and tube heat exchanger is designed. By setting up a support seat, a support plate, a through hole, a limiting plate, an installation groove, a limiting frame, a second trapezoidal block, a spring and a first trapezoidal block, a structure of the spring and trapezoidal block is used to reduce the amplitude of the heat transfer pipe and reduce wear and noise.

Benefits of technology

It effectively reduces the amplitude and wear of the heat transfer pipe, reduces noise during equipment operation, and extends the service life of the pipe.

Abstract

The invention provides a pipeline supporting structure for a shell-and-tube heat exchanger, and relates to the field of heat exchanger pipeline supporting equipment. The pipeline supporting structure for the shell-and-tube heat exchanger comprises a shell, tube plates are fixedly arranged on the two sides of the shell, a plurality of heat transfer tubes are arranged between the two tube plates, a plurality of baffle plates are arranged on the heat transfer tubes, and the baffle plates are fixedly connected with the inner wall of the shell. Through the arrangement of the supporting seat, the supporting plate, the passing hole, the limiting plate, the mounting groove, the limiting frame, second trapezoidal blocks, springs and first trapezoidal blocks, when the equipment operates, a heat transfer pipe vibrates and drives the supporting plate, the supporting plate can drive the first trapezoidal blocks, and then the first trapezoidal blocks extrude the two second trapezoidal blocks; and after being extruded, the two second trapezoidal blocks can move away from each other and extrude the springs on one side, and the springs can reduce the moving distance of the second trapezoidal blocks, so that the amplitude generated by the supporting plate and the heat transfer pipe is reduced, the abrasion of the heat transfer pipe is reduced, and the generated noise is reduced.
