The introduction of Reverse Pulse Dust Collector:

Also known as the reverse jet/reverse pulse dust collector, the reverse air cleaning baghouse collects dust which forms regularly forms into a hard 'dust cake' on the dirty side of the filter bag.  This type of a dust collector uses high-pressure ‘cleaning’ air, blown in the ‘reverse’ or opposite direction of the dust laden stream, to clean the dust cake.  Also called high pressure reverse fan cleaning, these models are continuous or ‘online’ cleaning dust collectors and mitigate the drawbacks of the ‘offline’ collectors. In these collectors, cleaning could be done continuously without interrupting the process and the numerous compartments that featured in the offline dust collectors were done away with.

These dust collectors are commonly used in wood dust filtering where dust loads are about 10-15 grains per cu.ft. The vent stream is generally positive. Additional positive pressure blowers can also vent into one collector. Though positive blowers are less efficient than backward inclined designs, they have their own advantages.

The Working Principle of the Reverse pulse  Dust Collector:

In a reverse fan cleaning dust collector, polluted air enters the filter bags from the inlet at the bottom and passes through the inside of the bag. Dust particles collect on the walls of the bag. A chain driven motor powered traveling manifold moves across the mouth of the envelope filter bags to provide the cleaning air. The flexing of the collecting bags causes the dust cake to crack and fall into the hopper. The reverse air stream can be used to clean one bag or one row of bags at a time.
These collectors can be installed on the same structures that support low pressure cyclone collectors 
Upgrading to other fabric collectors is easy with few changes in ductwork 
The reverse air fan provides great flexibility to positive pressure systems. Positive pressure systems have the capability of increasing the flow capacity by increasing flow through the reverse fan. By adding heat to the reverse air fan, any requirement of additional temperature spread between dry bulb and dew point temperature can be taken care of.

Since hopper openings are at atmospheric pressure in positive pressure systems dust collection is easily achieved. Hopper openings collect wood dust easily being 16-24 inches in diameter and thus prevent bridging of wood dust on opening. The reverse air fan cleaning collectors are used in grain collection and such processes.

Its  Advantages as follows:

1.Use of multiple fans divides branches of vent system with low and high pressure drops. Power draw can thus be reduced between different branches. Further system fans get activated only when specific branches are in operation. In these designs, dust cannot enter inactive branches due to the back draft dampers. 
2.Changes can be carried out easily to branches. For example change in airflow can be achieved by merely changing fan drive for individual branch. 
3.Single point collection of dust facilitates efficient disposal 
4.Hopper design (cone shaped) facilitates smooth flow of product to hopper outlet in comparison to other hopper designs 
5.These collectors can be installed on the same structures that support low pressure cyclone collectors
