High-pressure shell-and-tube heat exchanger, also often called high-pressure tubular heat exchanger, is a heat exchange equipment made of
stainless steel. It consists of many parallel stainless steel tubes, which are fixed on the tube sheet and surrounded by the shell. This heat exchanger is widely used in many industrial fields such as food processing, pharmaceuticals, chemicals, heating systems, etc. because of its strong corrosion resistance, hygiene, easy cleaning and maintenance.
Working principle of high-pressure shell-and-tube heat exchanger
The working principle of high-pressure shell-and-tube heat exchanger is based on heat conduction and convection heat transfer:
1. The hot fluid flows in the tube and transfers the heat it carries through the tube wall.
2. The cold fluid flows outside the tube, absorbs heat from the tube wall, and increases the temperature of the cold fluid.
3. The tube wall acts as a medium for heat exchange, transferring heat from the hot fluid to the cold fluid.
Application fields of high-pressure shell-and-tube heat exchanger
1. Petrochemical industry: used for heating, cooling, condensation and evaporation processes.
2. Food industry: used for heating and cooling of products such as milk, juice, beer, etc.
3. Pharmaceutical industry: used for heat exchange in product synthesis and preparation processes.
4. Energy industry: used for heat recovery and heat exchange in power generation.
5. Environmental protection field: used for heat recovery in wastewater treatment and waste gas treatment.
6. Heating and air conditioning systems: used for the exchange of hot and cold
water, providing heating and cooling.
High-pressure shell and tube heat exchanger structure
1. Shell: usually made of carbon steel or stainless steel, providing the external frame of the heat exchanger.
2. Tube bundle: composed of many stainless steel tubes, hot fluid and cold fluid exchange heat inside and outside the tube.
3. Tube sheet: used to fix the tube bundle and connect the tube to the shell.
4. Head: located at both ends of the shell, closing the shell and providing an interface for connecting the pipeline.
5. Baffle: installed in the shell, used to change the flow direction of the fluid, enhance turbulence and improve heat transfer efficiency.
Characteristics of high-pressure shell-and-tube heat exchangers
1. Corrosion resistance: Stainless steel material has good corrosion resistance and is suitable for a variety of chemical media.
2. High temperature and high pressure resistance: Suitable for high temperature and high pressure working environment.
3. Easy to clean and maintain: The tube bundle can be disassembled for easy cleaning and maintenance.
4. High heat transfer efficiency: Due to the turbulent flow of the fluid inside and outside the tube, the heat transfer efficiency is high.
5. Compact structure: Small size, small footprint, suitable for occasions with limited space.
6. Easy installation: Modular design, easy to install and disassemble.
7. Not easy to scale: The inner wall is smooth, reducing the possibility of scaling.
