A steam shield is set to prevent part of the steam from being dispersed into the environment, thereby avoiding waste and damage to equipment and personnel. The water retaining groove at the bottom of the steam shield can recycle condensed water formed by excess steam, further avoiding waste of resources. The steam injection amount and the width of the steam outlet can be quickly adjusted, so that the injection range and injection amount of the steam are respectively adapted to the size of the paperboard and the humidity requirement of the paperboard, so that the steam injection matches the required humidity of the paperboard, improves the quality of the paperboard, reduces the ineffective injection amount of steam, improves the use efficiency of steam, avoids waste of resources, and reduces production costs. However, the patent still has the following problems in actual use:

[0004] A steam hood is set up to prevent some steam from dispersing into the environment, thereby avoiding waste and damage to equipment and personnel. The water retaining groove at the bottom of the steam hood can recycle condensed water formed by excess steam, further avoiding waste of resources. However, water vapor needs to condense into more water on the surface of the steam hood before it can flow into the water retaining groove. However, after the water vapor condenses into water, the amount of water condensed into water at some locations is not enough, so that it cannot fall through its own gravity and flow into the water retaining groove, so that it will stay on the steam hood, thereby reducing the effect of recycling and saving water resources.
