Grey water discharging system for tree-shaped air duct

The utility model relates to a tree-shaped air duct grey water discharge system, which is characterized in that air filters are distributed in a tree shape in a structural air duct, the air filters on the same layer or at the same height are taken as a group, a plurality of groups of air filters are arranged in the structural air duct from top to bottom, and each group of air filters is provided with a branch pipe; the discharge pipes of the air filters in each group are connected in parallel and converged into the corresponding branch pipes, the branch pipes are converged into a header pipe, and an outlet of the header pipe is arranged outside the structural air duct. According to the utility model, the problem of discharge arrangement of a structural air duct filter or a demister can be well solved; the structure is simple, and pipeline calculation is clear; arrangement is convenient, structure outer plate holes are reduced, and the number of grey water discharging ports is reduced. 本实用新型涉及一种树型风道灰水泄放系统，在结构风
