Application of Gas Gas Plate Heat Exchanger in Waste Gas Heat Recovery

In coating machines, printing machines, and industrial drying processes, gas air plate heat exchangers are key equipment used to efficiently recover heat from exhaust gases and reuse it in the drying process to reduce energy consumption and improve drying efficiency. This device is widely used in various drying processes, including food, seafood, medicinal herbs, wood, agricultural products, coating, shaping, and other waste gas and heat recovery processes. It is particularly effective in scenarios that require efficient dehumidification.

Working principle of gas plate heat exchanger

A plate heat exchanger is a device that transfers heat between two airflows. It is composed of multiple layers of parallel arranged thin metal plates, forming two mutually isolated airflow channels between the plates. High temperature exhaust gas and fresh air flow through different sides of the plate for heat exchange. The core task of a heat exchanger is to:

Heat recovery: Recovering heat from the drying exhaust and preheating the fresh air entering the dryer, thereby reducing the energy required for heating the fresh air.

Reduce exhaust temperature: Through heat exchange, the exhaust temperature is lowered, reducing heat loss.

Improving system efficiency: By recovering heat, reducing energy waste, and enhancing overall drying efficiency.
