As a traditional heat exchange equipment, Shandong Kanglu shell-and-tube heat exchanger has a long history of application and is widely used in many industrial sectors, especially in the chemical, petroleum, energy and other industries. . It consists of a plurality of tubes, which form the heat transfer surface of the heat exchanger, and are also referred to as tube-and-tube heat exchangers.
The tubular heat exchanger consists of a housing, a heat transfer tube bundle, a tube sheet, a baffle (baffle), and a tube box. The casing is mostly cylindrical, and a tube bundle is installed inside, and both ends of the bundle are fixed on the tube sheet. The two types of hot and cold fluids for heat exchange, one flowing in the tube, called the tube-flow fluid, and the other flowing outside the tube, called the shell-side fluid. In order to increase the heat transfer coefficient of the fluid outside the tube, a number of baffles are usually installed in the housing. The baffle increases the speed of the shell-side fluid, forcing the fluid to pass laterally through the tube bundle multiple times over a specified path, enhancing fluid turbulence. The heat exchange tubes can be arranged on the tube sheets in an equilateral triangle or square. The equilateral triangles are arranged in a compact manner, the fluid outside the tube is highly turbulent, 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.
