Working Principle of Shell and Tube Condenser

The work of shell and tube condenser is based on the principle of heat exchange, i.e. heat transfer through the wall of the tube by utilizing the temperature difference between the two fluids. The specific process is as follows:

High-temperature and high-pressure steam or thermal fluid enters the shell course of the condenser, flows inside the shell and comes into contact with the outer surface of the tube bundle.

A cooling medium (e.g., cold water or air) flows inside the tube bundle and absorbs heat from the steam or thermal fluid in the shell process through the tube wall.

The temperature of the steam or hot fluid decreases as the heat is taken away, and it gradually condenses into a liquid, realizing the transition from gas to liquid.

The condensed liquid is discharged from the outlet of the shell process, while the cooling medium absorbs heat and increases in temperature, and flows out from the outlet of the tube process, completing the heat exchange process.

Advantages

High heat transfer efficiency: through the design of tube bundle and the role of folding plate, so that the two fluids can be fully heat exchange, improve the heat transfer coefficient.

Large handling capacity: can handle a large amount of steam or thermal fluid, suitable for industrial production of various scales.

Sturdy structure: the shell and tube bundles and other parts are made of metal materials, which can withstand high pressure and temperature, and have better stability and reliability.

Strong adaptability: According to different process requirements and working conditions, suitable parameters such as pipe material, pipe diameter, pipe length, number of shells, number of tubes, etc. can be selected to meet various heat transfer needs.

Convenient cleaning and maintenance: the tube bundle can be withdrawn from the shell, which facilitates the cleaning and maintenance of the inner and outer surfaces of the tubes and reduces the maintenance cost of the equipment.

Application fields

Electric power industry: used in thermal power plants, nuclear power plants, etc. to condense the spent steam discharged from the turbine into water to realize water recycling and improve power generation efficiency.

Petrochemical industry: In the process of petroleum refining and chemical production, it is used to condense various hydrocarbon vapors, organic vapors, etc., to realize the separation and recovery of products.

Refrigeration and air-conditioning industry: as an important part of the refrigeration system, it is used to condense high-temperature and high-pressure refrigerant vapors discharged from the compressor into liquid to provide conditions for the refrigeration cycle.

Pharmaceutical industry: In the process of drug production, it is used to condense organic solvents, vapors, etc. to realize the purification and concentration of drugs.

Food and beverage industry: used in food processing steam condensation, cooling and other processes, such as dairy production, beer brewing.
