Wound-tube heat exchangers have been applied to a certain extent due to their characteristics such as compact structure, ability to conduct heat transfer among multiple media, self-compensation for the expansion of heat transfer tubes, and facilitation of the large-scale development of heat exchangers. Today, we will introduce the energy-saving effects of the central-swirl guided coiled-tube condenser in wound-tube heat exchangers.
The shell volume of the spiral-wound heat exchanger condenser is 4 times the tube volume. This design can increase the fluid flow rate to improve the heat transfer film coefficient, with the fluid flow rate generally ranging from 3 to 5.5 m/s.
The interior of the spiral-wound tube heat exchanger adopts spiral threaded tubes wound in forward and reverse directions, with a gap of 2.5 mm between the tubes. This design of the spiral threaded tube heat exchanger enhances the turbulence effect of the fluid and eliminates dead zones, ensuring that all fluid participates in the heat transfer process.
The shell of the spiral-guided coiled-tube condenser in the wound-tube heat exchanger is made of micro-carbon stainless acid-resistant steel, which has excellent corrosion resistance and intergranular corrosion resistance. This material can be used as an important corrosion-resistant material in the chemical fiber industry, chemical industry, and fertilizer industry.
It occupies a small installation space, which reduces investment, lowers the workload and costs of installation, and simplifies installation and maintenance.
Its design features an asymmetric flow pattern. The heat transfer tubes are spirally wound inside the shell, with a length 4 to 6 times that of the shell.
This allows the gaseous medium to stay in the heat transfer tube bundle for a longer time, ensuring sufficient condensation and achieving a better condensation effect.
The spiral-guided coiled-tube condenser in the wound-tube heat exchanger is not only an important piece of equipment in large-scale chemical process operations but also an energy-saving device.
In addition to Wound-tube heat exchanger, GNEE also offers more high-quality products, such as volumetric heat exchangers, copper heat exchangers, titanium heat exchangers, heaters, chlorine coolers, high-pressure reactors, LPG storage tanks, cryogenic storage tanks, VPSA oxygen generators, etc. If you are interested in the above products or other products, please feel free to send an email to sales@gneeheatex.com, and our professional team will be happy to answer your questions.
