A quality dust collector is an important piece of equipment in your manufacturing process. When performing efficiently, it allows your machines to get maximum production rates, quality of finishes, long tool life, clear work environment, and lower operating cost.
In this article, we review the technologies and design parameters applicable for achieving quality, dependable low-maintenance dust extraction. We assume you operate in the timber or joinery and need a full factory extraction system.
We discard technology that is only suitable for single, or smaller, machine setups. These include:
- Shaker systems
- A Static bag units
- Cyclones; and
- All thing cartridges (cartridges are NOT appropriate for wood dust).
Components of a Dust Extraction System
#1: Cleaning Systems
An effective cleaning system is very important in maintaining system performance and long life of bag life. For reverse pulse cleaning, it is also important that the pulse valves and reservoir are sized properly. If not, the system is ravenous of air/pressure.
#2: Industrial Fans
The extraction fan is the engine of your dust system. It needs to overcome the whole system pressure loss while delivering the requisite air volume. The efficiency of the fan significantly impacts the running cost; the difference can be in the thousands per year. Understanding system pressure losses is important in optimal fan dimensioning.
Furthermore, Pulse-jet dust collectors have a superior initial pressure drop; around 1kPa. This is a design feature irrespective of design and brand. Dust collectors have a lower early pressure drop of around 300pa. The superior system pressure means you require a larger motor to achieve the same extraction volume. However, the difference in power requirement among a pulsejet and RAF system, for a 20,000 m3/h application, is about 11kW/h
#3: Inlet Design
The pulsejet should have a devoted inlet chamber to allow the dust to divide from the airstream. Lack of a dedicated inlet chamber is, unluckily, a commonly seen shortcut, taken to cut initial cost.
Moreover, Inlets located in the hopper section are not appropriate for pulsejets, as they result in a higher dust load accomplishment the filter bags. The can velocity disallows the dust to drop down and separate, causing an important reduction in filter bag life, cleaning competence, and performance.
The large hopper of the good pressure RAF filters allows for good dust separation and when combined with non-return valves, are the right options.
#4: Explosion relief
The timer dust is flammable and when combined with sufficient air (oxygen), extremely explosive. A full factory dust collector should have suitable and adequate explosion relief and non-return valves installed. However, the non-return valve prevents the fireball from an explosion traveling back into the factory through the ductwork.
#5: Filtration Velocity
The filtration velocity is debatable the single most significant design characteristic in quality dust control design. Incorrect filtration velocity by design is the most common cause for poor performance as well as premature bag life in the industry. Moreover, Requisite filtration velocity is based on air volume, filter media type, dust loading & dust type. This should be assessed by a properly experienced dust control engineer only.
