Participate in the activity: Replace the flue gas condensation tower’s heat exchanger with a bellows-type heat exchanger

Bricks are the solution: Firstly, they help save space. The condenser tower isn’t very large in terms of floor area, but it takes up a lot of space; this also leads to an increased amount of piping required. In contrast, bellows heat exchangers are compact, thus reducing the space they occupy； Second is investment; third is the heat exchange efficiency; fourth is the amount of water used for spraying – a large quantity is required in condensation towers

1. The overall heat transfer coefficient is more than 2 times that of carbon steel and stainless steel shell-and-tube heat exchangers； 2. High temperature and pressure resistance ； 3. Thanks to its fully circular flexible structure, it enables variable cross-sectional flow of the fluid, thereby creating positive and negative pressure differences; as a result, it has a very strong ability to remove and prevent scaling ； 4. The wall thickness is thin (0.8–1.0 mm); the corrugated structure of the wall generates no stress, there is no temperature gradient, and the fluid temperature becomes uniform almost instantly ； 5. Low pressure drop ； 6. The stress distribution is uniform, with no tearing occurring ； 7. The heat exchange tube bundle is removable, extractable, and can be serviced and cleaned ； 8. Under the same conditions, a heat exchange area of 60% that of carbon steel and stainless steel is sufficient to meet the operational requirements. 1# Qingtan Little Dragon

There is no need to stop the machine frequently for cleaning. Are the gas condensation tower and heat exchanger separate processes? Condense first, then cool?

Is the pressure drop of a bellows heat exchanger lower than that of a conventional heat exchanger? Why?
