Dust collection system ensures clean environment for pharmaceutical facility
N.R. Murphy has been providing dust collection solutions for more than 70 years.In that time, the company has helped many customers create clean, dust-freeenvironments.
One example is thecentral dust collection systemthat N.R. Murphy provided forthe pharmaceutical manufacturer Wyeth Limited. The facility had a number ofexisting individual dust collection systems, but they were proving inadequate.The new project was designed to replace all of them. In addition, the new systemhad to be large enough to accommodate a company expansion, whilemaintaining a clean and healthy work environment. The success of the projectdepended on meeting the requirements of both the Department of Labour andWyeth engineers.
System design and features
The solution N.R. Murphy provided included a continuous cleaning pulse jetcartridge filter unit. It was equipped with a top air-dust inlet for efficient diffusionand a blow back safety damper. To attenuate fan inlet noise, the system alsoincorporated an acoustically lined clean air plenum. This system also featuredease of servicing, thanks to quick opening access doors on the filter section.
The fan package selected for this project was a 23-inch, type EA-1 Murphy extraheavy-duty exhauster. It included a 100-horsepower T.E.F.C. motor equippedwith spring isolators to prevent vibration, and an inline discharge silencer tominimize noise.
For drum storage capabilities, the system included three hoppers with air-tightdrum connectors and proximity level detectors. The system also incorporated 12aeropleat filters and 12 microtrain H.E.P.A. filters downstream of the main filterunit and fan assembly. These filters act as a secondary precaution to preventdust escaping in accordance with emission standards.
Additional components and features of this system included the main controlpanel with an adjustable seven-day clock, a 100-horsepower motor starter, andphotohelic switches for the dust collector and safety filters.
System completion
Once the system was installed, N.R. Murphy performed air balancing of allbranch lines. The result was a fully functional exhaust system with satisfactory airperformance at dust pickup locations.
