Coating machine, heating shaping machine, tunnel furnace exhaust gas heat recovery device

A coating machine is a mechanical device used to evenly apply specific functional adhesives, coatings, inks, etc. onto the surface of a substrate and dry it, with a wide range of applications. For example, printing and packaging coating, textile and building materials anti-corrosion and waterproof coating, automotive sheet metal coating, optical coating for circuit boards, semiconductors, and lithium battery production coating.
The coating process of a coating machine mainly includes three steps: coating, drying, and winding. The drying process generates a large amount of waste heat during the heating process. Therefore, designing an effective waste heat recovery device can effectively reduce the energy consumption of the coating machine, which is important for its energy conservation and environmental protection.
Principle of residual heat recovery of coating machine
The waste heat recovery device of the coating machine uses a heat exchanger to recover waste heat. Using the waste heat gas emitted by the coating machine (coating machine) to preheat the new air, the preheated new air enters the oven through the pipeline, achieving the goal of energy conservation. The heat exchanger achieves waste heat recovery by exchanging heat between the hot air and flue gas generated during the drying process of the coating machine and the recovery medium (such as air, water, or other fluids). Hot air and flue gas flow through the heat exchanger through one side channel, while the recovery medium flows through the other side channel. The plate structure of the heat exchanger increases the surface area for heat transfer and improves the efficiency of heat recovery.
Advantages of Coating Machine Waste Heat Recovery Device
Compact structure, high heat transfer efficiency, and strong adaptability. They are suitable for heat transfer and energy recovery in high temperature, high humidity, and corrosive environments. Through a well-designed waste heat recovery system, lithium battery coating machines can operate more efficiently and reduce their impact on the environment.
