APC System Machine
We make industrial dust collectors, fabricated to customer needs - products that make sense to help factory workers and as a result help business owners be more productive
A dust collector is a system used to enhance the quality of air released from industrial and commercial processes by collecting dust and other impurities from air or gas.
Designed to handle high-volume dust loads, a dust collector system consists of a blower, dust filter, a filter-cleaning system, and a dust receptacle or dust removal system. It is distinguished from air cleaners, which use disposable filters to remove dust.

Fabric filters
Commonly known as
baghouses, fabric collectors use filtration to separate dust particulates from
dusty gases. They are one of the most efficient and cost effective types of
dust collectors available and can achieve a collection efficiency of more than
99% for very fine particulates.
Dust-laden gases enter the baghouse and pass through fabric bags that act as filters. The bags can be of woven or felted cotton, synthetic, or glass-fiber material in either a tube or envelope shape.
Fabric filters generally have the following parts:

Fabric filters generally have the following parts:
- Clean plenum
- Dusty plenum
- Bag, cage, venturi assembly
- Tubeplate
- RAV/SCREW
- Compressed air header
- Blow pipe
- Housing and hopper
Types of bag cleaning
Baghouses
are characterized by their cleaning method.
Shaking
A rod connecting to the bag is powered by a motor. This provides motion to remove caked-on particles. The speed and motion of the shaking depends on the design of the bag and composition of the particulate matter. Generally shaking is horizontal. The top of the bag is closed and the bottom is open. When shaken, the dust collected on the inside of the bag is freed. During the cleaning process, no dirty gas flows through a bag while the bag is being cleaned. This redirection of air flow illustrates why baghouses must be compartmentalized

Reverse air
Air
flow gives the bag structure. Dirty air flows through the bag from the inside,
allowing dust to collect on the interior surface. During cleaning, gas flow is
restricted from a specific compartment. Without the flowing air, the bags
relax. The cylindrical bag contains rings that prevent it from completely
collapsing under the pressure of the air. A fan blows clean air in the reverse direction.
The relaxation and reverse air flow cause the dust cake to crumble and release
into the hopper. Upon the completion of the cleaning process, dirty air flow
continues and the bag regains its shape.

Pulse jet
This type of baghouse
cleaning (also known as pressure-jet cleaning) is the most common. A high
pressure blast of air is used to remove dust from the bag. The blast enters the
top of the bag tube, temporarily ceasing the flow of dirty air. The shock of
air causes a wave of expansion to travel down the fabric. The flexing of the
bag shatters and discharges the dust cake. The air burst is about 0.1 second
and it takes about 0.5 seconds for the shock wave to travel down the length of
the bag. Due to its rapid release, the blast of air does not interfere with
contaminated gas flow. Therefore, pulse-jet baghouses can operate continuously
and are not usually compartmentalized. The blast of compressed air must be
powerful enough to ensure that the shock wave will travel the entire length of
the bag and fracture the dust cake.

Cartridge collectors
Cartridge collectors use perforated metal cartridges that contain a pleated, nonwoven filtering media, as opposed to woven or felt bags used in baghouses. The pleated design allows for a greater total filtering surface area than in a conventional bag of the same diameter, The greater filtering area results in a reduced air to media ratio, pressure drop, and overall collector size.
Cartridge collectors are available in single use or continuous duty designs. In single-use collectors, the dirty cartridges are changed and collected dirt is removed while the collector is off. In the continuous duty design, the cartridges are cleaned by the conventional pulse-jet cleaning system.
