Operational Mechanisms of the Dust Collection Systems

Maintenance of air quality is vital in any working environment. Dust removal systems do exactly this through removal of the particulate materials from the air and internal environment. A simple working formula of these systems is to capture, transmit and collect these impurities. Capturing is done through devices such as capture hoods, transmission through ducting system and final collection through either simple filters to more complicated devices like scrubbers or electrostatic precipitators.

Operation of Dust Collection Systems
The main aim of filtration is to remove particles from the air usually in the range of 2 – 10 micrometers and to handle large volume of air continuously. Simple dust collection systems operate via a single unit vacuum system to develop suction and complete air filtration. Particulate matter is pulled into the impeller and into a container of a bag. The clean air can then be re-circulated into the room.

Larger and more complex systems have a two stage process, which is able to isolate particles based on their sizes. Cyclone systems are a good example of these systems. The air can then be exhausted outside or can be re circulated back to the house or production facility.

Oxidizing Air Pollution Control Systems
Air pollution control systems use heat or elements with additives to stimulate oxidation reactions. These oxidizers “wash” polluted air through platinum or palladium and cause oxygen to separate and result to formation of non toxic waste products such as nitrogen and oxygen.

Non – Oxidizing Air Pollution Control Systems
These equipments use a different method to filter out impurities. They use air scrubbers (wet or dry) to complete the filtration. The dry types are able to remove gases like sulfuric oxides or hydrogen chlorides, by use of alkaline materials. Wet scrubber clean out dust and larger pollutants using water or other reagents. Electrostatic filters operate with electrical fields to clean out air. They clean out smoke, mists and liquid contaminants in the air.

Pulse Jet Cartridge
Pulse Jet Cartridge Filters type of filtration system is basically applied for areas with ambient temperature conditions and basically for free flowing dusts and materials. They are thus suitable for lighter to heavy volumes of particles in the air. Their typical processing volumes are 1.7 – 60 cubic meters of air.

Pulse Jet Hose Bag Type Filter
Some great advantages of this type of filters are they have longer life of the filter bags, lesser emission levels, reduced power consumption, and also lesser space requirement on the floor. They are very suitable where air flows are in very large volumes, higher temperatures, and harder to clean materials.

Furnace Fume Extraction Systems
They are applied in areas of operation where high heat is and fumes are generated. They serve to extract these flames and smoke from the sites or the workshop thus making the working environment pleasurable and friendly. These fumes are purified through the pollution prevention and treatment sites. Areas best suited are Induction furnaces, AOD furnaces, exothermic reaction furnaces and electric arc furnaces.
