That is, the steam relief port of the conditioner is connected to a φ300 stainless steel straight pipe, then to a cyclone, and after the cyclone, it is connected to a φ250 straight pipe to the roof. After connecting to the dehumidification fan, it is then connected to the environmental protection equipment.

[0003] Due to the change in the steam pressure used by the customer (0.4 - 0.6 MPa), the steam pressure increases, the flow rate becomes faster, and more dust enters the dehumidification air network.

Some materials are sucked into the environmental protection equipment, resulting in waste of raw materials and difficulty in manually handling the sedimented materials. Second, more steam is sucked away by the dehumidification fan, causing waste of energy. Summary of the Utility Model
