Product Description
Shell and tube heat exchanger is also called tubular heat exchanger. It is an inter wall heat exchanger with the wall of the tube bundle enclosed in the shell as the heat transfer surface. This kind of heat exchanger is simple in structure and reliable in operation. It can be made of various structural materials (mainly metal materials) and can be used under high temperature and high pressure. It is the most widely used type at present. Shell and tube heat exchanger plays an important role in chemical, petroleum, power, food and many other industrial production. In chemical production, it can be used as heater, cooler, condenser, evaporator and reboiler.
Shell and tube heat exchanger is composed of shell, tube bundle, tube sheet, baffle and tube box. The shell is mostly cylindrical, with tube bundle inside, and both ends of the tube bundle are fixed on the tube sheet. There are two kinds of cold and hot fluids for heat exchange, one flowing in the tube is called tube side fluid, and the other flowing outside the tube is called 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 shell side fluid, force the fluid to cross the tube bundle many times according to the specified distance, and enhance the degree of fluid turbulence. The heat exchange tubes can be arranged in equilateral triangle or square on the tube sheet. The equilateral triangle arrangement is compact, the turbulent degree of fluid outside the tube is high, and the heat transfer coefficient is large; the square arrangement is convenient for cleaning outside the tube, which is suitable for the fluid easy to scale.
Each time the fluid passes through the tube bundle is called a tube pass, and each time the fluid passes through the shell is called a shell pass. In order to increase the velocity of fluid in the pipe, a baffle plate can be set in the pipe boxes at both ends, and all pipes can be divided into several groups. In this way, the fluid only passes through part of the tube at a time, so it travels back and forth in the tube bundle many times, which is called multi tube pass. Similarly, in order to improve the flow velocity outside the tube, a longitudinal baffle can be installed in the shell to force the fluid to pass through the shell space many times, which is called multi shell side. Multi tube side and multi shell side can be used together.
