What is double tube sheet structure?

What is double tube sheet?

A double tube sheet is a design feature commonly used in shell-and-tube heat exchangers and other similar equipment. In a shell-and-tube heat exchanger, there are two main components: the shell, which is a large outer vessel, and the tubes, which are smaller tubes that run through the shell. The double tube sheet design involves having two separate tube sheets within the shell.

 

 

Double tube sheet heat exchangers are generally used in the following two situations:

One is to absolutely prevent the mixing of media between the shell and tube sides. For example, for heat exchangers with water passing through the shell side or chlorine gas or chloride passing through the tube side, if the water in the shell side comes into contact with chlorine gas or chloride in the tube side, it will produce highly corrosive hydrochloric acid or hypochlorous acid, which will cause serious corrosion to the material in the tube side. Adopting a double tube sheet structure can effectively prevent the mixing of two materials, thereby preventing the occurrence of the above-mentioned accidents;

 

Another scenario is when there is a large pressure difference between the medium on the tube and shell side. In this case, a medium is usually added to the cavity between the inner and outer tube sheets to reduce the pressure difference between the medium on the tube and shell side. This series of heat exchangers adopts a double tube plate structure design, which connects the tube side and shell side with their respective tube sheets, breaking the traditional practice of using the same connecting tube plate for both the tube side and shell side of a row tube heat exchanger. This minimizes the risk of cross contamination, facilitates timely detection of leakage hazards, and ensures safe production for users.

double tube sheet heat exchanger

 

 

How double tube sheet works?

1. Inner Tube Sheet: The first tube sheet is located inside the shell and is usually closer to one end. The tubes are attached to this inner tube sheet, and they pass through it to the other end of the shell.

 

2. Baffle Space: Between the inner tube sheet and the other end of the shell, there is a space that contains baffles. Baffles are plates or other structures designed to direct the flow of the fluid inside the shell and promote efficient heat transfer.

 

3. Outer Tube Sheet: The second tube sheet is located at the other end of the shell. The tubes are also attached to this outer tube sheet.

Whats the double tube sheet design advantages?

1. Prevents Cross-Contamination: Because there are two tube sheets, there is a space (the baffle space) between them. This helps to prevent cross-contamination between the two fluids flowing through the tubes, especially when they have different properties.

 

2. Enhanced Safety: In applications where one fluid is hazardous or toxic, the double tube sheet design provides an extra layer of safety by reducing the risk of leaks.

 

3. Reduced Risk of Thermal Expansion Issues: The double tube sheet design helps accommodate thermal expansion differences between the tubes and the shell. This is important to avoid problems that may arise from temperature-induced expansion and contraction.

 

4. Easier Inspection: The space between the tube sheets allows for easier inspection of the tubes and facilitates maintenance activities.tube sheet heat exchanger

 

 

In summary, a double tube sheet design is a configuration used to enhance the safety, efficiency, and ease of maintenance in certain types of heat exchangers, particularly those dealing with potentially hazardous fluids.

Electric Floor Heating Installation

Installing electric underfloor heating is a process that involves several steps and precautions to ensure the efficiency and safety of the system. Here are some key precautions for installing electric underfloor heating:

 

Preliminary preparation: Before installing electric underfloor heating, a needs assessment is necessary to clarify the area of ​​the house, the rooms used, and the desired underfloor heating effect in order to select the appropriate electric underfloor heating system. At the same time, choosing the right materials and equipment is also essential to ensure the stability and efficiency of the system. 1

 

Floor preparation: Make sure the floor is flat, dry, and free of debris. If the floor is uneven, leveling is required. The flatness of the floor is the basis for ensuring uniform heat dissipation of the electric underfloor heating system.

 

Installation of insulation layer and reflective mat: The insulation layer is used to prevent heat from going downward and improve heating efficiency. The reflective mat is used to reflect heat and further improve the heating efficiency. The installation of these two layers of materials must be uniform and tight to avoid gaps.

 

‌Install the electric heating cable or electric heating mat: According to the design plan, lay the electric heating cable or electric heating mat on the floor. The cables should be evenly distributed to avoid overlapping or crossing. The electric heating mat should be installed according to the requirements of the instructions, and the joints should be insulated.

 

‌Install the thermostat‌: The thermostat is an important part of the electric floor heating system, which is used to adjust and control the indoor temperature. The thermostat should be installed in places where the air temperature is uniform, and should not be installed in places where the temperature changes greatly, such as corners, doors and windows. ‌2

 

‌Lay a waterproof layer‌: Lay a waterproof layer on the electric heating cable or electric heating mat to prevent moisture from entering the electric floor heating system and protect the safety and service life of the electric heating cable or mat.

 

‌System test‌: Before laying the surface layer, the electric floor heating system must be tested to ensure that the system is fault-free before the next construction step can be carried out.

 

‌Power supply requirements and safety‌: Ensure that the power supply is safe and reliable, and comply with relevant electrical safety standards. The power cord should be of appropriate specifications and avoid series connection. ‌ 

 

‌Floor material selection‌: Select floor materials with good thermal conductivity to ensure that heat can be evenly distributed throughout the floor. Avoid using moisture-proof mat, because moisture-proof mat is heat-insulating and will affect heat transfer. ‌ 

 

‌Professional installation‌: The installation of the electric floor heating system must be carried out by professionals to ensure the normal operation and safe use of the system.  

 

Maintenance: After the electric floor heating is installed, the system must be cleaned and maintained regularly to ensure its normal operation and extend its service life.

 

By following these precautions, the safe, stable and efficient operation of the electric floor heating system can be ensured, providing users with a comfortable heating experience.
