Impact on scale formation during the shutdown of the heat exchanger

Heat exchangers are more prone to scaling during the annual major maintenance shutdown period. If internal standing water or condensate is not drained promptly or adequately, and the equipment is left in a relatively static state, scaling is more likely to occur. Therefore, attention should be given to the drainage and maintenance of the heat exchanger, especially when it is shut down for an extended period. Heat exchanger cleaning

To minimize or eliminate scaling conditions from a design perspective, the heat exchanger design is determined by calculating the economically reasonable heat transfer area and related structural dimensions of the heat exchanger to achieve the desired heat transfer objectives. In the structural design, consider adopting special structures, such as designing structures that generate turbulence. For critical heat exchange equipment, it may also be considered to install electronic descaling devices, backflushing systems, etc. If water is used as the heat exchange medium, and considering corrosion, materials such as anti-scaling additives should be used. In addition, adhering to simple design principles can also reduce or eliminate external conditions conducive to scaling, such as: impure and scaling-prone fluids should be routed through the tube side, as tube side cleaning is more convenient.

Fluids with low flow rates or high viscosity are best processed through the shell side, as the fluid flows in the shell side with baffle plates, where continuous changes in flow rate and direction lead to turbulence, thereby preventing scaling from forming.

Corrosive fluids should flow through the tube side to prevent both the tubes and shell from being corroded simultaneously, and the tube side is also easier for maintenance and replacement.

Coolant fluids should flow through the shell side; chemical plant exchanger cleaning, can utilize the shell's external heat dissipation effect, and it is also convenient to replace after scaling on the tube side. Exchanger cleaning

With the rapid development trend of intelligent industrial production, the demand for cooling circulating water is increasing. At the same time, due to the inability to receive scientific and reasonable cleaning, the dirt in many reciprocating system exchange machines often requires organic chemical cleaning for newly established heat exchangers before startup. This is to eliminate high-temperature oxidation scale and silicon oxide scale generated during production and manufacturing, as well as rust, weld marks, fine sand, oil film coatings, and contaminants formed during storage, transportation, and installation.

Step: Scale Cleaning

Add the prepared descaling cleaner at a ratio to the cooling circulating water in the cleaning tank, initiate the cleaning and descaling of the heating furnace, and determine the duration of the cleaning cycle and the amount to add based on the amount of scale. Once all the scale has been cleaned, proceed to the next cleaning procedure.

: Clear Water Wash

After connecting the cleaning machinery and heating furnaces, use the fresh water recirculation system to clean for 10 minutes, inspect the system status for leaks, exchange the cleaner company, and at the same time, remove rust.

Step 3: Remove Corrosion Cleaning

Add surface stripping and release agents to the cooling water in the cleaning tank based on the proportion, run the recirculation system for 20 minutes to separate scale and the components being cleaned. Meanwhile, apply rust prevention treatment to surfaces without scale to prevent the cleaning agent from corroding the cleaned components during descaling.

Step 4: Passivation Coating Solution

Add passivation coating agent; implement passivation coating solutions for the heating furnace cleaning system software to prevent pipe and component corrosion and the conversion of new rust into scale.

High thermal conductivity and strong thermal radiation capability

High-quality sealing is a key feature. It's not necessary to replace the rubber gaskets when cleaning heat exchangers. The issue lies in the quality of the rubber gaskets. As the name suggests, rubber gaskets are used for sealing purposes; in the construction of plate heat exchangers, they are used to seal between the plates, preventing media leakage from the production line and providing an elastic function between the plates. Cleaning the heat exchanger...

Plate heat exchangers are always in a clamped state during assembly, only reverting to their original shape during disassembly and cleaning; at the same time, the plates are subjected to pressure during disassembly, assembly, pressure testing, and use, causing some degree of deformation. Having understood the "assessment" of the quality of the plates and rubber gaskets during heat exchanger cleaning, let's talk about the "plate reshaping" process available now. After cleaning the disassembled plates, they are placed in specially machined molds, undergo a re-pressing process at Zhanjiang Heat Exchanger Cleaning, and are then repressed. The plates produced this way ensure both the original processing accuracy and quality of the plates, with performance as good as new. Heat exchanger cleaning
