Shell and Tube Exchangers

Introduction

Shell and Tube Exchangers are composed of shell, heat transfer tube bundle, tube sheet, baffle plate (baffle plate) and tube box. The shell is mostly cylindrical with a tube bundle inside, and both ends of the tube bundle are fixed on the tube plate. The fluid flowing in the tube is cold and hot, called the tube side fluid; the other flowing outside the tube is called the shell side fluid. In order to improve the heat transfer coefficient of the fluid outside the tube, several baffles are usually installed in the shell. The baffle can increase the velocity of the fluid in the shell side, forcing the fluid to pass through the tube bundle multiple times at a specified distance, and enhancing the turbulence of the fluid. The heat exchange tubes can be arranged in an equilateral triangle or square on the tube plate. The equilateral triangle arrangement is relatively compact, the fluid outside the tube has a high degree of turbulence, and the heat transfer coefficient is large; the square arrangement is convenient for cleaning outside the tube and is suitable for fluids that are easy to scale.

Applications

It has a wide range of applications and can be widely used in thermal power, factories and mines, petrochemicals, urban central heating, food and medicine, energy electronics, machinery and light industry, etc.
