In the product drying industry, the application scenarios of gas-to-gas platular heat exchangers are diverse. Through heat recovery, temperature regulation, and energy saving, they bring significant improvements to drying processes across various fields.
Grain processing enterprises need to dry wheat, corn, and other grains to reduce moisture and extend storage time. Traditional drying equipment directly heats fresh air, leading to high energy consumption and operational costs.
Solution:
Install a gas-to-gas platular heat exchanger to recover heat from discharged high-temperature exhaust gas, preheat fresh air, and deliver it to the drying tower.
Actual Results:
Heat utilization efficiency increased by 30%.
Drying costs reduced by approximately 20% per ton of grain.
Prevents damage to grain quality (e.g.,color and nutritional value) caused by excessive temperatures.
Scenario Description:
Furniture manufacturers need to dry wood to reduce moisture content and prevent deformation or cracking. However, traditional combustion heating methods result in high energy consumption and uneven drying.
Solution:
Adopt a gas-to-gas platular heat exchanger to recover heat from exhaust gas, preheat the circulating airflow in the drying kiln, and precisely control drying temperature.
Actual Results:
Drying time shortened by 20%-30%.
Improved uniformity in wood moisture content, enhancing product quality.
Energy consumption reduced by 25%, resulting in significant annual cost savings.
Scenario Description:
In the drying of food products such as dried fruits, vegetables, and tea leaves, excessive temperatures may compromise flavor, color, or nutritional content.
Solution:
Use a gas-to-gas platular heat exchanger to recover heat from exhaust gas and preheat fresh air while maintaining precise temperature control within the drying chamber (e.g.,60℃-70℃).
Actual Results:
Improved food color and flavor.
Drying time reduced by 15%.
Fuel costs reduced by approximately 30%.
Scenario Description:
After paper formation, paper mills require high-temperature drying to remove excess moisture. However, the drying process is energy-intensive, accounting for over 30% of total production costs.
Solution:
Integrate a gas-to-gas platular heat exchanger into the drying equipment to recover heat from exhaust gas, preheat fresh air, and recycle it for reuse.
Actual Results:
Equipment thermal efficiency improved by 35%.
Annual natural gas cost savings of millions of RMB (based on a medium-sized paper mill).
Enhanced drying uniformity, reducing paper deformation rates.
Scenario Description:
In ceramic production, green bodies need to be dried to an appropriate moisture level before entering the kiln. Traditional heating methods waste significant energy, while high-temperature exhaust gas emissions impact the environment.
Solution:
Use a gas-to-gas platular heat exchanger to extract heat from exhaust gas, preheat air in the drying chamber, and lower exhaust gas temperatures.
Actual Results:
Energy consumption reduced by approximately 18%.
Improved drying uniformity of ceramic green bodies, reducing cracks.
Compliance with stricter environmental standards.
High-temperature exhaust gas discharged during product drying typically contains significant recoverable heat. Gas-to-gas platular heat exchangers transfer this heat to fresh air or process gases for subsequent drying processes, reducing direct fuel or electricity consumption. Simultaneously, these heat exchangers provide stable temperature regulation for drying media, ensuring that product quality is not compromised by temperature fluctuations.
