Bag Filter

Why it is Needed:

Air pollution is the presence of high concentration of contamination, dust, smokes etc., in the general body of air man breaths. Dust is defined as particulate matter as “any airborne finely divided solid or liquid material with a diameter smaller than 100 micrometers.” Dust and smoke are the two major components of particulate matter. Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles. In fact, dust when inhaled can increase breathing problems, damage lung tissue, and aggravate existing health problems. In addition to health concerns, dust generated from various activities can reduce visibility, resulting in accidents. Therefore, every federal Govt. has stringent regulations which require prevention, reduction and/or mitigation of dust emissions.

Why this APC Equipment:

• It is Air Pollution Control equipment which filters air through passing infected air through the special fabric bags which let air pass but collects particulates in it.
• Power plants, steel mills, pharmaceutical producers, food manufacturers, chemical producers and other industrial companies often use baghouses to control emission of air pollutants.
• Unlike electrostatic precipitators, where performance may vary significantly depending on process and electrical conditions, functioning baghouses typically have a particulate collection efficiency of 99% or better, even when particle size is very small. 

Conclusion:

Bag Filters a 1970s innovation is still popular due to its 99% efficiency irrespective of electrical conditions of plant and less CAPEX as compared to other APC equipments.
