A pressure vessel venting, dust collecting, and noise silencing system for continuous venting of dry process air during the filling and depressurization of pressure vessels configured to contain, for example, barite or the like, by filtering of vented air through a filter media, with the air discharge being controlled by a pressure sensor actuating a depressurizing regulator valve, located between the vessel and the filter. The present system contemplated a filter which may be cleaned by reverse pulse pressurization or backwash, thereby providing low maintenance filtration while preventing particle emissions into the atmosphere. The present system utilizes a high capacity, stacked filtration medium, which provides a greater filtration, with a surface contact area far in excess of the present systems on the market, which primarily rely upon bag house filtration. The present system thereby provides a low maintenance, efficient, and relatively cost effective system of controlled, filtered, and silenced venting on a process which would otherwise emit particulates into the air, while generating a significant amount of noise in the process.
