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.

Wood drying waste heat recovery plate heat exchanger

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.

The function of plate heat exchanger
Improving energy efficiency: Plate heat exchangers play a crucial role in data center cooling systems. Through an efficient heat exchange process, plate heat exchangers can effectively transfer the heat generated by servers to the cooling water, which is then released into the atmosphere through the cooling tower. This efficient heat exchange process not only improves the energy efficiency of data centers, but also reduces energy consumption and operating costs.
Optimize temperature control: Plate heat exchangers can accurately control the temperature and humidity inside data centers, ensuring that server equipment operates in a suitable environment. By adjusting the flow rate and temperature of cooling water, plate heat exchangers can meet the cooling needs of different data centers, ensuring the stable operation and efficient performance of server equipment.
Energy saving and environmental protection: The use of plate heat exchangers helps reduce the impact of data centers on the environment. By using environmentally friendly materials and energy-saving technologies, plate heat exchangers can reduce energy consumption and emissions, in line with the concept of sustainable development. Meanwhile, the efficient heat exchange process of plate heat exchangers also reduces waste of natural resources, providing strong support for the green operation of data centers.

How a Double Rotor Setup Works

1. The enthalpy/adsorption rotor dehumidifies and cools the hot and humid outside air.

2. The cooling coil further dehumidifies the outside air until the requested humidity level is reached.

3. The sensible rotor reheats the outside air to the required supply air temperature.

4. At the same time, the exhaust air is cooled which increases the efficiency of the enthalpy/adsorption rotor.

回転式熱交換器はどのように動作するのでしょうか?

ホイールは、平らな箔と波形の箔の2枚からなるマトリックスで構成されており、これらが組み合わさって空気が通過する通路を形成します。ホイールは電動モーターとベルト駆動システムによって回転します。
回転の半分では、内部空間からの排気がマトリックスを通過します。熱はマトリックスに蓄えられ、回転の残りの半分では、外部からの新鮮な供給空気に伝達されます。
流路の大きさはウェル高さと呼ばれます。ウェル高さとホイールの直径が異なると、効率、圧力損失、空気流量が異なります。
適切に構築、設置、保守された回転熱交換器では、粒子に結合した汚染物質の移動はほぼゼロになります。

回転式熱回収外気ユニットの原理

回転式熱回収外気ユニットの主要部品は、蓄熱体としてハニカム状に巻かれたアルミホイルで作られた円盤状の蓄熱ホイールです。運転中、外気は熱交換器の一方の半円を通過し、排気はもう一方の半円を反対方向に流れます。蓄熱ホイールは動力機構の作用で毎分約10回転の速度で連続回転し、蓄熱体は高温の半円側で常に加熱され、熱を吸収します。低温の半円側に回転すると冷却され、熱を放出します。このプロセスが繰り返され、排気から一部のエネルギー（冷熱）が外気に回収されます。アルミホイルの表面に吸湿材をコーティングして、完全に加熱されたローターを作成します。気流中の水分は吸湿コーティングに入り、ローターが別の気流に達すると放出されます。ローター式熱回収外気ファンは、外気と排気の間の顕熱と潜熱の交換を利用してエネルギーを回収する構造になっており、省エネと良好な換気の維持を実現します。夏季には外気を予冷・除湿し、冬季には予熱・加湿することができます。
