1. What is a Spiral Plate Heat Exchanger?

A spiral plate heat exchanger is a high-efficiency, compact heat exchange device composed of two metal plates wound into a spiral shape, forming two separate flow channels sealed through full welding. During heat exchange, hot and cold fluids flow through their respective spiral channels, facilitating efficient heat transfer. Spiral plate heat exchangers are known for their high heat transfer efficiency, compact structure, and strong self-cleaning ability, making them suitable for various industrial applications.

Compared to traditional shell-and-tube heat exchangers, spiral plate heat exchangers require less space for the same heat exchange area. Additionally, the spiral flow pattern promotes stable turbulence, reducing fouling accumulation and improving heat exchange efficiency.

2. What is a Large-Scale Spiral Plate Heat Exchanger?

When the heat exchange area reaches 450㎡ with a diameter of up to 4 meters, such large-scale spiral plate heat exchangers provide enhanced heat transfer capacity, meeting the demands of high-flow, high-temperature, and high-pressure conditions.

However, while we have the capability to manufacture spiral plate heat exchangers exceeding 4 meters in diameter, we strongly recommend keeping the diameter below 1.8 meters for better transport, installation, and maintenance feasibility. A smaller diameter ensures greater stability, reduces installation challenges, and optimizes operational costs and lifespan.

3. Technical Features of a 450㎡, 4m Diameter Spiral Plate Heat Exchanger

(1) High-Efficiency Heat Transfer, Optimized Energy Consumption

Large-scale spiral plate heat exchangers utilize a fully welded structure to minimize heat loss and enhance heat transfer efficiency, ensuring effective thermal energy utilization and reducing energy consumption.

(2) Wide Channel Design for High-Viscosity Fluids

The internal wide-channel design allows the heat exchanger to handle high-viscosity fluids such as coking wastewater, heavy oil, and sludge, reducing clogging and improving operational stability.

(3) High Pressure and Temperature Resistance for Longevity

Advanced welding technology enables the exchanger to withstand pressures of several megapascals (MPa). The corrosion-resistant materials make it suitable for high-temperature and aggressive environments, such as chemical plants and refineries.

(4) Compact Design, Easy Installation and Maintenance

Compared to traditional shell-and-tube heat exchangers, spiral plate heat exchangers offer a more compact structure, saving space while also incorporating self-cleaning capabilities that reduce maintenance frequency.

4. Application Scenarios

(1) Petrochemical Industry

Used for heavy oil heat exchange and coking wastewater preheating, improving energy efficiency.

(2) Steel and Metallurgy

Utilized for high-temperature flue gas waste heat recovery, enhancing thermal energy utilization and reducing production costs.

(3) Environmental Protection

Applied in wastewater treatment and biogas heating, helping industries achieve energy conservation and emissions reduction goals.

5. Key Considerations When Selecting a Large-Scale Spiral Plate Heat Exchanger
