Product description

General Introduction

The shell-and-tube heat exchanger is also known as a tube and tube heat exchanger.

It is a partition wall heat exchanger with the wall surface of the tube bundle enclosed in the shell as the heat

transfer surface. This heat exchanger has a simple structure and reliable operation.

It can be manufactured with 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.

The shell and tube heat exchanger still dominates.

It has the characteristics of sturdy structure, large operating flexibility, strong adaptability, high reliability

wide range of material selection, large processing capacity

and can withstand high temperature and high pressure widely used.

As the temperature of the fluid inside and outside the tube is different, the temperature of the shell of the heat exchanger and the tube bundle are also different. If the two temperatures are very different, a large amount of thermal stress will be generated in the heat exchanger, causing the tube to bend, break, or pull off from the tube sheet. Therefore, when the temperature difference between the tube bundle and the housing exceeds 50°C, appropriate compensation measures need to be taken to eliminate or reduce thermal stress. According to the compensation measures adopted, shell and tube heat exchangers can be divided into the following main types
Fixed tube-plate heat exchangers (TUBE-SHELL )The tube plates at both ends of the tube bundle are integrated with the shell, the structure is simple, but only suitable for heat exchange operations when the temperature difference between the cold and hot fluids is not large, and the shell side does not require mechanical cleaning. When the temperature difference is slightly larger and the shell pressure is not too high, an elastic compensation ring can be installed on the shell to reduce thermal stress.
U-tube heat exchanger (TUBE-SHELL )Each heat exchange tube is bent into a U shape, and the two ends are fixed on the same tube plate in the upper and lower areas, and are divided into two entrance and exit rooms by means of the partition in the tube box. This type of heat exchanger completely eliminates thermal stress, the structure is simpler than the floating head type, but the pipe side is not easy to clean.

Main control parameters of shell and tube heat exchanger The main control parameters of the shell and tube heat exchanger are heating area, hot water flow rate, heat exchange amount, heat medium parameters, etc. Selection points 1) According to the known flow rate of cold and hot fluids, the initial and final temperatures and the specific heat capacity of the fluid determine the required heat exchange area. Initially estimate the heat transfer area, generally assume the heat transfer coefficient, determine the heat exchanger structure, and then check the heat transfer coefficient K value. 2) When selecting a heat exchanger, pay attention to the pressure level, operating temperature, and connection conditions of the interface. Under the premise that the pressure drop and the installation conditions allow, the shell and tube heat exchanger is selected to be an elongated type with a small diameter, which is conducive to increasing the amount of heat exchange. 3) The pressure drop of the heat exchanger should not be too large, generally controlled between 0.01~0.05MPa; 4) The flow velocity should consider the fluid viscosity. The flow velocity with large viscosity should be less than 0.5 ~ 1.0m/s; the flow velocity in the general fluid tube should be 0.4 ~ 1.0m/s; the fluid that is easy to scale should be 0.8 ~ 1.2m/s. 5) A filter should be installed before high temperature water enters the heat exchanger. 6) The combined result of single processing and configuration of heat exchangers in the heat exchange station should meet the total heating load and regulation requirements of the heat exchange station. Under the premise of satisfying the user's heat load adjustment requirements, the number of heat exchangers in the same heating coefficient should not be less than 2 units, and should not be more than 5 units. Key points for construction and installation of shell and tube heat exchangers 1) The heat exchanger should be tested for water pressure at 1.5 times the maximum working pressure. The steam part should be no less than the steam supply pressure plus 0.3 MPa; the hot water part should not be less than 0.4 MPa. Under the test pressure, keep the pressure for 10 min. 2) The front end of the shell-and-tube heat exchanger should have space for removing the tube bundle, that is, the distance of its head to the wall or roof should not be less than the length of the heat exchanger, and the net width of the equipment operation channel should not be less than 0.8m. 3) The installation height of various valves and instruments should be easy to operate and observe. 4) The vertical clear distance from the highest point of the upper part of the heater (generally referring to the safety valve) to the lowest point of the building structure should meet the requirements of installation inspection and should not be less than 0.2m.
