AI Technical Summary
In existing chemical heat exchange equipment, MTBE and C4 organic media are prone to localized polymer scale buildup during heating, leading to a surge in flow resistance and heat transfer attenuation. Furthermore, existing solutions pose a risk of leakage due to seal failure, making it difficult to achieve stable and efficient dual-heat-source stepped preheating and online rapid recovery.
The plate-type energy-saving heat exchange device, composed of fully welded corrugated plate bundles and annular solid metal baffles, combined with a pneumatic diaphragm regulating valve, achieves in-situ high-efficiency cleaning through a micro-boiling phase change scrubbing mechanism. It utilizes herringbone corrugations to generate microbubbles to peel off the scale layer, and dynamically adjusts the heat source flow rate through control methods to achieve heat transfer recovery.
It achieves reliable stepped preheating within a single pressurized space, reduces floor space, significantly improves heat transfer recovery capability, avoids defects such as seal failure and downtime for cleaning, and realizes efficient heat transfer recovery and equipment self-operation.
