Recycle hot air from the oven exhaust? ? ?
Thread Content
After drying the fabric, how can the moisture in the exhaust gases be removed and the residual heat effectively recovered? How can the hot air generated after drying be reused in the oven? What methods can be used for this? The oven temperature is 190–210 degrees, the fabric humidity is 5–10%, and the exhaust gas temperature is 120–140 degrees. Seeking advice~~:)
A simple consideration allows the exhaust gas to heat the air entering the oven； Depending on the process conditions, it can also be reused directly ； It depends on the condition of your manufacturing process and the existing design requirements of the equipment ； Theoretically, there is no problem
Thank you. Do we not need to remove the water vapor from the exhaust gas? Should the heated exhaust gas be fed directly into the intake?
In the case of gas-phase heat exchange, there is basically no need to consider water vapor issues； However, if it is used directly, the issue of water vapor drying must be taken into account; moreover, it is necessary to assess what drying method would be appropriate by considering the air humidity at that temperature :)
We want to use it directly; how can we remove the moisture?
Install an inlet air heater to recover heat by using the heat from the exhaust gas at the outlet; after the temperature of the exhaust gas drops as a result of this heat exchange, install a cooling separator to separate and remove the water. I’m not sure if that’s what it means. . . Indirect drying is straightforward, but for direct drying, it is necessary to consider the impact of the separation effect between air and the material on equipment clogging
