[0002] In recent years, with the improvement of people's living standards and the enhancement of environmental awareness, dispersible non-woven fabric as a new type of environmentally friendly material has been widely used in personal care, medical health, home cleaning and many other fields. The continuous growth of market demand has prompted the continuous expansion of the production scale of dispersible non-woven fabric. Dispersible non-woven fabric needs to be dried during production.

[0003] At present, many drying equipment for dispersible non-woven fabric production has the problem of low efficiency in the utilization of heat energy.
