Dust collectors are used in many processes to either recover valuable granular solid or powder from process streams or to remove granular solid pollutants from exhaust gases and work environments.

Who Took Our Poll?Top
The factors influencing dust cake buildup and .... combination of new membrane technology and state-of-the-art felt substrates. ... Typical new equipment design efficiencies are between 99 and 99.9%. ... influencing dust resistivity and must be carefully considered in the collection efficiency
Development of new fabric/ felt for bag manufacturing. Development of high temperature duct collector bags. Better surface area and air to cloth ratio in same size dust collectors. Improved air inlet and discharge etc. Improved cleaning technology i.e. efficient pulse jet tech.
The new materials for frame and structure, especially the ones I use in oil rigs to prevent corrosion fire and smoke poisoning. New materials for ducts are also considered beside the design to avoid curves and long distances from air intake to air supply point..
In my point of view, the leaders in innovative dust collectors in Europe are Mikropul Germany and Ultrafilter UK.
Applications and UseTop
In oil rigs, where space is a problem, I was hired to re-engineer and reconstruct air intakes of dust/brine/ash collectors because of the need of areas in some oil rigs of Petrobras, the Brazilian Oil Company. Also to re-engineer air intakes of diesel engines rooms in order to supply enough combustion air for stoichiometric mixture (AFR) needs. Same for fun coils in super shoppings positioned around sea shore and therefore maintenance caused by brine was a big problem. My efforts now is to eliminate dust confinement in the dust collectors by applying new coalescing air filters elements showing high spatial areas and stratification areas to reduce pressure loss and bacterial growth.
I am work in American company and business based in cocoa processing. We are using some type of dust collector. We use dust collector for cleaning cocoa bean, separation of dust and cocoa powder. Now, I am designing dust collector for separation of wet dust and vapour on vacuum drying system.
Coal, Perilium Coke, Limestone, Cement Grinding application. Material Handling applications. Fine powder handling and metering application. Nuisance dust collector for transfer points. Process dust collectors for different applications.
I saw collectors for mineral coal in steel mills which made me feel like working inside of an explosive weapon. Collectors for volatiles coming from cooking are also very common, but again too dangerous.
Use of regular, reverse air dust collector as process dust collector for cement grinding unit. Higher moisture content made it really difficult to operate efficiently and there were several plugged bags. Also dedusting of hot air from clinker cooler. Due to very high temperature (red hot clinker particles being carried in gas stream) of particles in gas stream resulted in multiple bag failures.
Yes. Use of an inefficient fan resulted in caked-on grain dust in the duct work of a Great Plains state's baghouse. When a highly efficient Industrial Air Technology Corp. impeller wheel was substituted and the fan was turned on, the caked-on dust was released & the baghouse had to be shut down for emergency clean-out!
The main thing I would like to see improved would be for the system to be quieter during operation; not from the standpoint of the mechanical portion, but at the workstations where the air (&dust) is removed. The greater the suction, the noisier it is.
Easier access to filters, better spark traps, better use of energy on motors, lower static pressure inside the units, longer filter life, fewer chances of fires, better compliance with explosion vents
Ease of installation and maintenance. Since I install and maintain most every brand, I find that there are a few that do not think about the extended maintenance that is required for repairs.
