Ventilation system design for air supported structure of coal storage

Presents the design thought of ventilation system for air supported structures of coal storage, and analyses its design calculation method, equipment selection, inside and outside pressure difference control and numerical simulation of air distribution. To prevent the dust from re-entrainment inside and outside the air supported structure caused by ventilation system, the indoor air enters the air outlet through the air duct, and the outdoor air exhaust adopts water bath dust removal method. In consideration of the indoor occupation health and safety protection requirements, dust and gas monitoring facilities are set up inside the air supported structure.
