subject: Aerodyne Dust Collector Solves Difficult Separation Problems [print this page] Aerodyne specializes in solving difficult material handling problems such as dust collection, and the separation of fine particulates from air and gas streams. These problems become especially difficult when the particulate matter is abrasive, fibrous, sticky, hygroscopic, or has a high temperature. These characteristics tend to clog filter media, or even damage cartridges, bags, and filter housings or their internal mechanisms, such as bypass valves or pressure indicators.
In applications such as these, Aerodyne cyclone dust collectors are often used by themselves, or ahead of bag houses and cartridge filters to extend the service life of those devices. The companys S Series Dust Collectors are particularly effective because of their counter-cyclonic design, which removes particles down to 20 microns or smaller in size without clogging or damage to the housing. The particulate matter can then be easily disposed of, or recycled where practical.
Cyclone dust collectors have other advantages over filter media. Filters often do not allow collected particulates to be recovered for reuse. Also, installed before a bag house on high heat processes, a cyclone dust collector can act as a spark arrestor. Furthermore, unlike filters, cyclone dust collectors actually work more efficiently as humidity increases.
Manufacturers and processors can use an Aerodyne S Series Dust Collector as part of a production process, or to meet OSHA standards for dust control in the workplace. These dust collectors can handle particulates such as sawdust, fly ash, sand, coffee and many other materials. Units of different size are available for flow rates from 50 cfm to 18,000 cfm. Their counter-cyclonic design allows them to be mounted vertically or horizontally, providing cost-saving flexibility to meet space restrictions in new and existing application.
The unique design of the S Series ensures that a minimal amount of particulate will come in contact with the collector walls. This feature allows the units to easily handle highly abrasive materials without special anti-abrasive coatings or extra heavy duty construction.
Principles of Operation. In operation, an S Series Dust Collector has the primary particle-laden air or gas stream enter near the particulate collection end (hopper) of the cylindrical housing. This stream moves through a spinner mechanism as it proceeds toward the opposite (exhaust) end of the unit. At that end, a secondary air/gas stream enters and spins toward the hopper end. The centrifugal effect that the spinner mechanism has on the primary air stream forces dust particles toward the cylinder wall. However, the secondary air/gas stream intercepts the particles, forcing them toward the hopper where they are collected for disposal or reuse. As a result of this separation, the cleaned air/gas stream exits at the exhaust end of the housing.
This counter-cyclonic design with its secondary air stream reduces wear on the inside of the cylindrical housing and increases separation efficiency. Because of this, and there are no filter cartridges or bags to replace, the S Series Dust Collectors require little maintenance. The only moving part is a blower to assure proper air/gas stream velocity.
