Advanced Inlet Technology

Advantaflo™ Inlet Technology

Short bag life, abrasion of the hopper, high pressure drop, and excessive compressed air consumption are the basic problems caused by uneven gas flow distribution to the filter elements in pulse-jet collectors. The uneven gas distribution is caused by the design of the dust collector's inlet diffuser or target plate. The solution to solving these common problems is MikroPul's patented Advantaflo™ Inlet technology. MikroPul has researched gas flow dynamics since 1990, and in Figures 1-3 we will show the common problems associated with poor inlet design.

Figure 1: Without any inlet diffuser, high gas and dust velocity, up to 2,000 fpm or higher cause abrasion at the bottom and sides of the bags.

Figure 2: With an inclined plate diffuser high velocity circular flow patterns are created. Dust being pulsed off the bags is re-entrained as it tries to fall into the hopper causing excessive pressure drops.

Figure 3: Vortex air flow patterns are created in the lower portion of the hopper, again causing re-entrainment and difficulty in removing dust from the hopper with the perforated housing type diffuser.

By using MikroPul's Advantaflo inlet technology we've created a new inlet diffuser that eliminated the problems caused by these typical inlet designs.

Figure 4: Shows our patented Cascadair™ inlet diffuser. This diffuser evenly distributes the incoming gas flow into the collector by uniformly diverting a portion of the gas at each of the number of successive orifice plates.

The results achieved:

1) Longer bag life
2) Lower deltaP
3) Eliminates dust re-entrainment
4) Gas flow capacity is significantly increased

The Cascadair inlet can be retrofitted to any dust collector with a hopper inlet, even those manufactured by our competitors.

Laboratory studies and actual field installations show the Cascadair inlet diffuser improves filter performance in all areas by 10 to 15%.
