Dust Collection Systems

Dust collection systems are a critical part of several industries. Their design and engineering have to match the needs of the industry where they are being used with the main purpose of controlling, reducing, and removing contaminants, harmful matter, gas fumes, and dust. They are engineered to purify and filter air so that it can be released into the surrounding environment or the workspace.
Each industry has a different array of pollutants and harmful particles to be removed. Dust collectors must meet the specific extraction needs required by each industry to provide optimum air purification.
As the standards for clean air have become more rigid, manufacturers of dust collection systems have risen to the demand and produced air purification devices that meet and exceed government requirements.

The most common form of dust collecting system is the baghouse. It is the most efficient system and uses a fan to create a vacuum to force contaminants through a filter in a bag. Baghouse methods are divided by how they clear their filters. The shaker method shakes the filter to remove the collected dust, while the pulse jet version uses a burst of air when a sensor detects the filter is full. The reverse air method forces fresh air through the filter. Some industries that use baghouse systems are powder coating companies, cement plants, paper manufacturers, and rubber recycling.

Pulse bag type dust collector is consist of upper box, middlebox, underbox, dust removal system and jetting system.

1.Upper box is includes cover plate and air outlet.

2.Middle box is includes perforated plate, filter frame, sock and venture.

3.Under box is includes ash hopper, air intake and access door Jetting system contains control valve, pulse electromagnetic value, injection pipe and air pocket.

Dust cakes on the outside of the bags and is removed down into collection hoppers by a blast of compressed air or motion. They operate continuously to collect particles of any size. The design of the system allows for easy access for maintenance.

Working Principle

During the dust gas goes into middle box and under box,the dust can be attached to filter bag and outgoing gas after going through venture and upper box. With the increasing of dust, press loss for dust bag is increased, which will fed back to controller. Receiving and issuing commands, the controller will touch off every pulse valve to make gas erupts from each jetting hole, then pass a venture tube and spray into corresponding filter bag. The filter bag expands rapidly under instantaneous reaction of airflow, dust fallen off of the filter bag, so the filter bag can be recycled.

Benefits of Dust Collection System

As the number of regulations and standards for air pollutants rises, dust collection systems are becoming a necessity, though, at one time, they were considered an add-on luxury. Manufacturers of dust collection systems keep a strict watch on government standards and design systems that expertly adhere to the requirements.

Aside from the various regulations, there are practical reasons for installing a dust collection system. The first consideration is the protection of the health of workers who have to work in gas-filled and dust-saturated environments.

When deciding to install a dust collection system, there are certain factors that should be considered. Though less expensive systems may be more attractive for financial reasons, the most important factor is the quality of the air in the workspace and the area around the facility.

Fire Suppression

Whenever there is a concentration of dust and gas, there is always the potential for fire. By having a dust collection system, especially one with a spark arrestor, the concern for fire is significantly reduced. A dust collection system has dust constantly moving, which prevents it from collecting and becoming a hazard.

Explosion Proofing

Prior to the development of dust collection systems, dust explosions, especially in woodworking shops, were very common. The problem was so prevalent that many shops had a wall open to the outside. Much like fire prevention, dust collection systems keep air moving and circulating to prevent the possibility of dust collecting sufficiently to produce an explosion bubble.

Odor Reduction

Air in a dust collection system is constantly circulating and being refreshed, which assists in keeping odorous contaminants out. Though dust collection systems may get confused with air conditioning, they have far more benefits. When polluted air is sent through filtration, it removes the contaminants and odors they create. Odor reduction is not common in all dust collection systems. Where odor is a concern, carbon-impregnated filters are used.

Respiratory Health

One of the major areas of concern for the Occupational Safety and Health Administration (OSHA), the National Institute for Occupational Health and Safety (NIOSH), and the Center for Disease Control (CDC) is the safety of the workspace for workers. Regarding dust and contaminants, they have specific requirements regarding the allowable percentage of particulates in a cubic foot of air. Violation of these standards can lead to a business being closed, which makes it essential to install an acceptable dust collection system.

Personal Safety

Something that is rarely considered in an industrial environment is the cleanliness and quality of the floor. One of the benefits of a dust collection system is the removal of the need to constantly clean the floor. There may be slight accumulations during a workday, but a dust collection system significantly reduces the need to sweep the floor or dust off a workspace.
