Whenever a bulk solid is subjected to physical movement, crushing and cleaning air in the surrounding is displaced and carries fine particles of that object with it. When these fine particles are in very high concentration they are known as dust which normally spreads all over the surroundings and pollutes the environment. It causes pollution by dirtying the nearby surfaces, soiling the air thus making it difficult to breath and also by coating the leaves of the nearby vegetation leading to their death. Therefore there is need for installation of dust extraction systems in the affected areas so as to protect the environment.These are systems that filter dust out of air and collect it so as to dispose it off later. They clean the air in working places ensuring that the workers work properly and machines do not breakdown. There are several types of this system.Separating the particles from the gas stream involves three steps. First of all the particles are made humid by the liquid. This increases their size and mass which makes them easier to collect. They then come into contact with the liquid and get attached to it.There are several types of these extractors.industrial ventilation fume extraction dust extraction exhaust ventilation welding fume technology home family business hobbies advice Continue reading →
