A dust collector is a system used to enhance the quality of air released from industrial and commercial processes by collecting dust and other impurities from air or gas. Designed to handle high-volume dust loads, a dust collector system consists of a blower, dust filter, a filter-cleaning system, and a dust receptacle or dust removal system.
Wood dust becomes a potential health problem when, for example, the wood particles, from processes such as sanding, become airborne and are inhaled. Wood dust is a known human carcinogen . [ 10 ] [ 11 ] Certain woods and their dust contain toxins that can produce severe allergic reactions. [ 12 ]
The collector uses a mark-sweep algorithm. It provides incremental and generational collection under operating systems which provide the right kind of virtual memory support. (Currently this includes SunOS[45], IRIX, OSF/1, Linux, and Windows, with varying restrictions.) It allows finalization code to be invoked when an object is collected.
Wood-dust concentrations vary with type of dust extraction, amount of wood removed, and type of sander (Thorpe and Brown 1994). [2] For electric belt sanders used to sand dowels , total dust concentrations ranged from 0.22 mg/m with external dust extraction to 3.74 mg/m without extraction, and concentrations of respirable dust ranged from 0.003 ...
An automated vacuum waste collection system, also known as pneumatic refuse collection, or automated vacuum collection (AVAC), transports waste at high speeds through underground pneumatic tubes to a collection station where the waste is compacted and sealed in containers. Full containers are transported away to be emptied.
For applications where there is relatively low dust loading and gas temperatures are 250 °F (121 °C) or less, pleated, nonwoven cartridges are sometimes used as filtering media instead of bags. [4] [5] Dust-laden gas or air enters the baghouse through hoppers and is directed into the baghouse compartment. The gas is drawn through the bags ...
Collections Management Systems have their origins in cataloging and registration, and consequently, most systems manage information and records “from a curatorial and collections management perspective." [44] Conservation information in these systems is often limited to condition reporting and documentation of treatment history. While some ...
Other languages, such as C and C++, were designed for use with manual memory management, but have garbage-collected implementations available. Some languages, like Ada, Modula-3, and C++/CLI, allow both garbage collection and manual memory management to co-exist in the same application by using separate heaps for collected and manually managed ...
