Do you know why dust collectors are considered an integral part of an industry, and its overall importance? Well, just like we use air purifiers to reduce excess dust at home, similarly industries use this unique system to boost the quality of air at work. These dust collectors are used in factories, warehouses, plants, and other commercial buildings to remove harmful dust from the surroundings. It comprises a blower, dust filter, a filter-cleaning system, and a dust receptacle or dust removal system. All these components come together to ensure workplace safety. Since its presence can lead to allergies, asthma problems, or to a variety of nose, throat, and lung cancers it is important to get rid of harmful air from your premises.
It has been specially designed to remove the contaminated dust or gas from the air in the industry. It is important to note that there are four distinct types of collectors, which are inertial separators, filtered collectors, wet scrubbers, and electrostatic precipitators. They help in eliminating the last particle of dust from the air. Dust collection is an online process for collecting any process-generated dust from the source point on a continuous basis. It acts as an effective controller of air pollutants that can have health hazards.
Various Filters for Dust Collection
Filters used during dust collection are essential components in the entire process. Prior to the augmentation of an advanced filter material to capture fine dust, it was done with a 30-micron polyester bag. These bags acted as a carrier of dust; however, it was difficult to capture the fine one. Particulate smaller than 10 microns remained in the air the longest, penetrated deepest into the lungs, and was the hardest for the body to filter or eliminate. Finally, industries understood its importance and started using finer filters, without hampering the airflow. Read the different categories of filters below:
Shaker Dust Collectors: It is better known as a baghouse dust collector. This cylindrical bag collects dust, particles, even the sticky ones. It is durable, flexible, and has a greater service life. Another reason for its acceptability is the less frequent need for filter replacement. It is used in foundries, steel mills, the mining industry, power plants, and smelting industries.
Cartridge Collectors: These are a special type of filters that fits in a small space and needs fewer filters. Its compact design is ideal for small space operation. This filter can be changed from outside at your convenience with minimal freak incidents. It fits well in industrial and commercial places and has the ability to filter fine dust generated from powder coating, metalworking, woodworking, fume collection, thermal spray, pharmaceutical manufacturing.
Cyclone Dust Collector: All the dust is sucked into the cyclone chamber that transcends into the dust collecting bucket. In the next stage, the pure air is pushed from the funnel cloud to the filter before getting dispersed. The cyclone system has the capacity of removing large over 20 microns and heavy particles, along with fine dust. It is used in woodworking, pulp and paper, shot blasting, mills, grain and agriculture, recycling plants, and many other industries.
Pulse Jet Dust Collector: Pulse jet models are another common type of industrial dust collector. It can be customized easily, and is capable of handling a wide range of temperatures and pressures, and has great efficiency. These are used in manufacturing units like chemical and mineral industry, food, and metal industry. The system operates in various stages to meet the ultimate demand.
Electrostatic Precipitators: Electrostatic precipitator utilizes electrostatic forces to segregate dust particles from exhaust gases. It is mostly used at industrial hubs that burn fossil fuels such as oil and coal for electricity. In this process, the air-borne particles flow within the chamber from the negative to the positive electrode. Thereby, getting caught in the collector.
The system of dust collection can significantly vary in different plants. These are different types of dust collectors that you will find in the market. You can choose the one that matches your requirement. Some of them come at affordable pricing, while others can be costly.
