1. A baghouse, also known as a baghouse filter, bag filter, or fabric filter is an air pollution
control device and dust collector that removes particulates or gas released from
commercial processes out of the air. Power plants, steel mills, pharmaceutical
producers, food manufacturers, chemical producers, and other industrial companies
often use baghouses to control the emission of air pollutants.
Unlike electrostatic precipitators, where performance may vary significantly depending
on the process and electrical conditions, functioning baghouses typically have a
particulate collection efficiency of 99% or better, even when particle size is very small.
Baghouses are classified by the cleaning method used. The three most common types
of baghouses are mechanical shakers, reverse gas, and pulse jet.
MECHANICAL SHAKERS:
In mechanical-shaker baghouses, tubular filter bags are fastened onto a cell plate at the
bottom of the baghouse and suspended from horizontal beams at the top. Dirty gas
enters the bottom of the baghouse and passes through the filter, and the dust collects on
the inside surface of the bags.
REVERSE AIR:
In reverse-air baghouses, the bags are fastened onto a cell plate at the bottom of the
baghouse and suspended from an adjustable hanger frame at the top. Dirty gas flow
normally enters the baghouse and passes through the bag from the inside, and the dust
collects on the inside of the bags.
PULSE JET:
In reverse pulse-jet baghouses, individual bags are supported by a metal cage (filter
cage), which is fastened onto a cell plate at the top of the baghouse. Dirty gas enters
from the bottom of the baghouse and flows from outside to inside the bags. The metal
cage prevents the collapse of the bag.
Timely Cage Inspection
A thorough inspection of the cage is highly
recommended each time new bags are
installed. Some of the most frequent and
common problems to look for when
inspecting a cage include: bent and
damaged wires, rusting and pitting, and
sharp edges along the bottom of the cage
pan.
Checking Pressure Drops
Perhaps the most important indication of a
dust collector’s performance is the
differential pressure (resistance of air
across the filters and clean air plenum).
This measurement gives you an indication
of whether your filters are operating
correctly.
Check Cleaning
System
Ensuring your pulse jet
dust collector cleaning
system is operating
properly is an imperative
and proactive maintenance
necessity.
Ensuring proper
Bag-to-Cage fit
The fit between the bag
and the cage is critical for
filters to perform properly.
Filters that are too lose or
too tight will have severely
limited collection efficiency
and may fail prematurely.
Proper Selection of
Filter Bags
Maximum Inlet Operating
Temperature, Inlet grain
loading, particle size, gas
stream velocity, gas stream
moisture level are the main
parameters on which the
filter bags are selected
