No doubt about it. Fumes and odors are not only unsightly but also can cause health hazards. Never mind a horrible stench at times. Yet what type of advice and expertise is available in the ventilation and heating trades to deal with these matters? Is it a simple matter of not buying a home or property nearby an abattoir meat packing plant or industrial setup that may use solvents in their manufacturing processes? Or should a home or office building buyer be more wary when selecting to move into an area. Should any potential buyers or scouts be noting which way the wind or areas and routes that real estate agents take you on any given day in relation to wind and weather conditions? Even then after moving into any given area, an unannounced and unexpected auto body repair show may open up upwind of you releasing their toxins downstream to you by airstream. Yet in the end what can be done for you – even after local, city or even federal rules, regulations and statutes are employed and adhered to?
First in the process is the type of material which needs to be removed from the air or atmosphere. Is it filterable by any simple or standard means? On top of that is the amount to be filtered within reason of any of the standard, acceptable standard means and formats to be used? Chief considerations in this area are 1) size of particles 2) Determining if the actual cause of the odor or odors filterable? For example solvents are often not filterable by any degree and must be trapped at source. Material properties should be listed as well. For example is there anything in the air which could damage the collector once set up it. For example corrosive materials such as acids and alkali, sticky materials such as metallic buffing dusts from buffing compounds as well as abrasive materials from sandblasting exhaust can all work to damage collectors. Basically “collectors” must be matched with the materials to be collected to prevent damage and damages.
One other consideration is what happens in the future long after the original planners and contractors are gone. Often not thought up until events and situations raise their ugly head years later, are situations and events that with the results and questions of methods and even geographical placement of disposal not considered or dealt with at inception. Tailing ponds in an industrial process might be one example. Everything seems great, until years later when effects are noted, or local areas of disbursement and disposal are found or noted. By then, it may be far too late in time as dispersal and contamination may well have taken place and occurred. To clean up a toxic spill, contaminated area can need large amounts of effort and expense. Make these considerations long early in the planning process when choosing means and types of air cleaning devices. It does not have to be size and caliber of the offshore BP oil leak to be a major or even minor disaster.
In terms of the types of dust collectors that are on the marketplace and as well are both economical and suitable for art processes and other small operations: cyclone collectors and fabric collectors. Both are widely used in industry and are available in various sizes from commercial suppliers. Another type of dust collector, electrostatic precipitators have somewhat more limited use and usages. Cyclones, also-called “centrifugal “collectors remove coarse to medium-sized particles by spinning the air in which they are contained in a cone-shaped chamber. Electrostatic precipitators (ESP) remove fine particles and fumes from the atmosphere by placing an electrostatic charge on the particles, then attracting these particles to an oppositely charged collection plate. ESP’s are actually quite effective at collecting particles and reducing their prevalence to almost nil. Still they have a specific, limited flow rate which can only be increased somewhat in practical terms past a given total flow rate or rates.
In the end , or at the end of the selection process of an air cleaning device or devices both particulate size and the degree of final collection are in the heating and ventilation trade the usual two most major determinants of the final decision of which type or types of air and atmospheric devices chosen in any project .
