Shell and tube heat exchanger

Recuperative surface industrial equipment includes shell and tube heat exchangers, which are actively utilized for heat exchange and thermotechnical processes between interacting mediums. This type of heat exchanger emerged as one of the first and still dominates the market share. This is because in most industrial processes, there is a necessity for economically and efficiently transferring heat to maintain the normal operation of the system. Installing a shell and tube heat exchanger optimally addresses this task:

1. It possesses enhanced thermodynamic characteristics, allowing for faster heating or heat recovery compared to other types of heat exchange equipment.
2. It boasts a wide range of operating parameters, making it easily adaptable to various technological processes and types of mediums. Shell and tube heat exchangers are less sensitive to the quality of the fluids involved in the heat exchange process.
3. The reliable construction of a shell and tube heat exchanger makes it resistant to hydraulic shocks and temperature fluctuations.

The structure of shell and tube heat exchangers

The basis of heat exchangers of this type is the tube bundle, consisting of straight or bent elements. They are fastened on supports (tube sheets) in such a way that the tube and inter-tube space are optimally separated. Tube sheets have a lattice structure and are made of sheet steel with a thickness of 20 mm or more.

The classical scheme of a multi-pass shell and tube heat exchanger includes several partitions that direct the flow of liquid and increase the intensity of its movement. Their presence contributes to the creation of turbulent flows of the heat transfer medium, which increases the heat exchange rate of the entire apparatus.

The tube system is secured within the shell – the heat exchanger housing, which is welded from steel sheets with a thickness of at least 4 mm. The housing has several flanges for the inlet and outlet of the mediums involved in the heat exchange process. Heat exchangers are categorized into single-pass, double-pass, and four-pass shell and tube heat exchangers. Production of heat exchangers with different numbers of passes is also permissible. You can purchase a shell and tube heat exchanger in two types: vertical and horizontal. The vertical type is more commonly used when working with gaseous mediums since its spatial orientation facilitates condensate drainage. Horizontal placement allows for the creation of heat exchangers of larger dimensions, thus enabling operation with increased heat capacities. The installation of these devices is achieved through high-strength supports located on the housing.

The advantages of using shell and tube heat exchangers

The need for the production of such type of heat exchangers arose over a century ago when existing systems ceased to meet the industrial demands. Shell and tube heat exchangers could be utilized as devices for heating, cooling, condensing, and evaporating. They also facilitated the transition of mediums between different states of matter.

Industrial enterprises needed to purchase shell and tube heat exchangers due to their ability to operate at high pressures and temperatures. They also offered increased reliability, excellent performance, and relatively simple maintenance (cleaning of the units occurred sectionally, thus not requiring as much energy as in other types of heat exchangers).

Among the main advantages of the described type of equipment are:

1. The ability to manufacture passage sections in a wide variety of sizes.
2. Modernization with reinforced tubes and temperature compensation systems. This includes shell and tube heat exchangers with a floating head, lens compensator, or U-tubes.
3. Heat-resistant, cold-resistant, acid-resistant, and other types of materials are involved in their production.

Due to the flexible design of this type of heat exchanger, it easily adapts to various environments, technological conditions, and industrial needs. Therefore, shell and tube heat exchangers have a wide range of applications. They are used in petroleum refining and chemical industry,metallurgy, heat supply,pharmaceuticals, food industry , refrigeration, and also pulp and paper industry and so on.
