1, the first method, installation and use of exhaust purification equipment: the specific method is to install a steam collection hood near the main source of steam in the workshop, install a strong pipeline exhaust fan in an outdoor or indoor idle position, and connect the exhaust fan with the steam collection hood through an exhaust pipe. When the exhaust fan is working, the steam is sucked into the exhaust pipe by the powerful exhaust capacity and suction of the exhaust fan, sent to the air purification facility, and discharged after purification and drying.

2. The second method is to install a high-power industrial ventilator: install an industrial ventilator with a large exhaust volume on the wall or window or even the roof near the source of steam generated in the workshop. When the ventilator is powered on, the steam in the workshop can be quickly pumped out with the airflow, which reduces the accumulation and residence time of steam in the workshop. The installation of industrial ventilator is suitable for all kinds of workshops, with little damage to the site, low cost and good effect of rapid steam extraction. The disadvantage is being pulled out of the room.
