Product description

Concept of waste heat recovery:
The steam consumption of the dryer of the paper machine is mainly from the following points:①the heat of drying wet paper②the heat emitted by the drying equipment body③the heat taken away by the paper④the heat taken away by the condensed water⑤the heat of fresh air temperature rise(wet air exhaust).Among them,the first three items are based on equipment and paper type,and their fluctuations are not large.What can be changed is the heat taken away by the condensate and the heat taken away by the exhaust air.Waste heat recovery is to use the available heat of the condensate and the sensible and latent heat of the exhaust air.


Description of waste heat recovery unit:
After air filtration,the fresh air supplemented from the outside of the workshop enters the shell and tube steam waste heat recovery device.The fresh air goes through the shell side,and the hot and humid air discharged from the hood goes through the tube side.Heat exchange is carried out through the heat conduction pipe wall,so as to reduce the temperature of the wet air and increase the temperature of the fresh air entering the hood.After passing through the steam and gas waste heat device,the fresh air enters the condensate heater again for further heating,and at the same time,the temperature of the condensate is reduced,So as to achieve the effect of waste heat reuse.
