Description

Technical Field

[0001] The utility model belongs to the technical field of drainage control and relates to a fire water control system, in particular to an electrostatic degreasing fire water control system. Background Art

[0002] Some chemical products, such as film, require a calendering process during production. This process generates fumes, which are then treated and discharged via an electrostatic degreasing system located on the rooftop.
