Energy Saving Pillow Heat Exchangers Strong Adaptability Continuous Welding

Strong adaptability continuous welding pillow plate heat exchangers designed for maximum energy efficiency and performance in demanding industrial applications.

Our core heat transfer enhancement technology features advanced three-dimensional flow channel design. The complex channels formed by concave and convex plates create continuous fluid direction and speed changes, generating strong disturbance and mixing effects. Computational fluid dynamics (CFD) optimized plate surfaces increase the Nusselt number by 40%-60% while maintaining low pressure drop coefficients, delivering superior "strong heat transfer, low energy consumption" performance ideal for precision chemical and microelectronics industries requiring exact temperature control.

As a core component of Jiangsu Ruiding's catalytic incineration systems, our plate heat exchangers handle exhaust gases containing propylene, propane, formaldehyde, acetaldehyde, acrolein, acetic acid, and acrylic acid on the cold side, while managing hot flue gas from catalytic reactions on the hot side.

With catalysts being highly sensitive to temperature variations, our heat exchangers maintain temperature stability within ±2℃ of design specifications before and after catalytic reactions, ensuring optimal reaction efficiency.

Heat load capacity of 3930 kW handles large exhaust gas flows (63,935 Nm³/h cold side) with 382℃ inlet temperature differential (505℃→240℃ hot side). S30408 stainless steel construction provides excellent resistance to high temperatures (505℃) and corrosion from organic acids including acrylic acid, ensuring long-term operational reliability.

Cold side outlet temperature increases from 123℃ to 280℃ while maintaining catalytic reaction temperature fluctuations within ±2℃, preserving catalyst activity and reaction efficiency.

Effectively handles corrosive components including acrylic acid and formaldehyde in cold side exhaust gases. Advanced anti-blocking plate design minimizes coking risks.
