During the heat setting process of textiles, a large amount of waste heat energy is usually generated. In order to effectively utilize this waste heat energy, a plate aluminum foil heat exchanger can be used for recycling.
The working principle is as follows:
Plate heat exchanger is an efficient heat exchange device commonly used to transfer heat between two fluids. In the textile heat setting machine, the plate heat exchanger can be placed at the hot air discharge port or flue gas discharge port of the heat setting machine. During the process of contact with the plate, the hot air or flue gas transfers heat to the recovery medium. After absorbing the residual heat energy from hot air or flue gas, the recycling medium can be used to heat water or other fluids for preheating, heating, or other thermal energy requirements in the textile process.
By using plate heat exchangers, textile heat setting machines can recover the waste heat energy from the discharged hot air or flue gas, reduce energy consumption, and improve energy utilization efficiency. This helps to reduce production costs, minimize environmental pollution, and contribute to the sustainable development of the textile industry.

princípio de funcionamento:
O núcleo de recuperação de calor residual da granulação e secagem de caldeiras a gás alcança uma troca de calor eficiente através da circulação de fluido de trabalho com mudança de fase gás-líquido em um tubo fechado. O gás de exaustão e o ar fresco (ou ar que precisa ser aquecido) trocam calor através do núcleo de troca de calor do trocador de calor de placas, e o calor do gás de exaustão é transferido para o ar fresco através do núcleo de troca de calor, fazendo com que a temperatura do ar fresco aumente.
Áreas de aplicação:
Este sistema é amplamente utilizado em indústrias como cerâmica, fertilizantes, produtos químicos, ração animal, purificadores de água e materiais de construção, sendo adequado para situações que requerem ar de combustão ou gases de processo em alta temperatura. Por exemplo, ao utilizar um sistema de recuperação de calor residual para recuperar o calor residual dos gases de combustão em alta temperatura provenientes do resfriador circular, a eficiência energética do processo produtivo pode ser melhorada e o consumo de energia reduzido.
Em resumo, o núcleo de recuperação de calor residual da granulação e secagem de caldeiras a gás permite a recuperação e reutilização do calor residual dos gases de escape por meio de um mecanismo eficiente de transferência de calor, reduzindo custos de produção, melhorando a eficiência do uso de energia e diminuindo a poluição ambiental. Podemos personalizar a solução de recuperação de calor residual mais adequada com base nas condições específicas do local de produção e nas suas necessidades.

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.

In the conventional drying process of wood, the traditional ventilation method results in significant heat loss due to the removal of moisture and exhaust gas. The forced ventilation and waste heat recovery system in the wood drying room is a new technology that improves the indoor and outdoor dry wet air exchange process in drying production and effectively recovers waste heat.
The counterflow plate heat exchanger adopts high-quality hydrophilic coated aluminum foil, epoxy resin coated aluminum foil and other materials. The two air streams enter the channel in reverse, increasing the heat transfer area. The fresh air and exhaust air are completely separated to avoid the transmission of odors and moisture. Fast thermal conductivity, no secondary pollution, achieving ventilation and heat recovery functions.
