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

Heat recovery for livestock and poultry houses: plate heat exchangers or rotary heat exchangers

The heat recovery products used in livestock and poultry houses mainly recover the heat energy in the exhaust through the principle of heat exchange and use it to preheat the fresh air entering the house. This not only ensures the minimum ventilation required in winter, but also reduces the heating energy consumption inside the building. This technology usually uses heat recovery ventilation equipment, such as plate heat exchangers or rotary heat exchangers, which can effectively capture the heat in the exhaust while ensuring the quality of the fresh air supply.

The main advantages include:

Reduce energy consumption: By recovering heat, the use of external heating equipment is reduced, significantly lowering energy costs.
Ensure air quality: Although heat recovery is carried out, it will not affect the circulation of air in the house, and the minimum ventilation rate can still be ensured to maintain the air quality in the livestock and poultry house.
Improving comfort: Preheating fresh air helps maintain a suitable temperature inside the house, reduce stress reactions in livestock and poultry, and improve production efficiency.
This technology is particularly important in cold winter regions as it can significantly reduce heating energy consumption while providing a healthy living environment for livestock and poultry.

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.

How does a rotary heat exchanger work?

The wheel is built up by a matrix that consists of two foils, one flat and one corugated;together, they create channels for the air to pass through. The wheel is rotated by an electricmotor and belt drive system.
In one half of the rotation, the exhaust air from the inside space flows through the matrix. ltsheat is stored in the matrix, and in the other half of the rotation, it is transferred to the freshsupply air from outside.
The size of the channel is called well height. Different well heights and diameters of thewheel give different efficiencies, pressure drops, and airflow rates.
Rotary heat exchangers that are properly constructed, installed, and maintained have almostzero transfer of particle-bound pollutants.

Principle of rotary heat recovery fresh air unit

The main component of the rotary heat recovery fresh air unit is a disc-shaped heat storage wheel, which is made of aluminum foil wound into a honeycomb shape as the heat storage body. During operation, fresh air passes through one half circle of the heat exchanger, while exhaust air flows in the opposite direction through the other half circle. The heat storage wheel rotates continuously at a speed of about 10 revolutions per minute under the action of the power mechanism, and the heat storage body is constantly heated on the high-temperature half circle side, absorbing heat; When rotating to the low-temperature semicircle side, it is cooled and releases heat. This process repeats itself, recovering some of the energy (cold and heat) from the exhaust air into the fresh air. A moisture absorbing material is coated on the surface of the aluminum foil to create a fully heated rotor. The moisture in the airflow enters the moisture absorbing coating and is released when the rotor reaches another airflow. The composition of the rotor type heat recovery fresh air fan is to use the exchange of sensible and latent heat between the fresh air and exhaust air to recover energy, achieving energy conservation and maintaining good ventilation. In summer, the fresh air can be pre cooled and dehumidified, and in winter, it can be preheated and humidified.
