China Citric Acid Production Line Waste Air Heat Recovery System

1. Finned tubes used for improve heat transfer, combined finned tubes for heat exchange, increase heat transfer area, reduce cost;
2. Low air flow velocity in shell side, low resistance loss;
3. Multi-tube side arrangement, different kinds of process fluid in different temperature can be arranged at same time;
4. Compare with traditional heat exchanger, small heat strain rate, not easy to be damaged, safety for using;
5. Tubes are multi-tube side arranged, convenient to drainage and washing, cleaning can be done without shutdown;
6. Highly effective water, power and steam saving;
7. Air system or cold and hot air heat exchanger (air heater), pressure balance inside and outside heat exchange tubes, non-pressure operation achieved; problem of bacteria in air due to leakage of heat exchange tubes of traditional air heater, stable operation and energy-saving ensured.
