Air pollution control device that removes particulates out of air or gas released from commercial processes or combustion for electricity generation. Power plants, steel mills, pharmaceutical producers, food manufacturers, chemical producers and other industrial companies often use bag filter to control emission of air pollutants.
: It consists of a number of small-diameter cyclones, operating in parallel and having a common gas inlet and outlet operating on the same principle as single cyclone separators—creating an outer downward vortex and an ascending inner vortex. Multiple-cyclone separators remove more dust than single cyclone separators because the individual cyclones have a greater length and smaller diameter. The longer length provides longer residence time while the smaller diameter creates greater centrifugal force. These two factors result in better separation of dust particulates. The pressure drop of multiplecyclone separators collectors is higher than that of single-cyclone separators, requiring more energy to clean the same amount of air.
Cyclone separators are found in all types of power and industrial applications, including pulp and paper plants, cement plants, steel mills, petroleum coke plants, metallurgical plants, saw mills and other kinds of facilities that process dust.
SINGLE CYCLONE DUST COLLECTOR: They create a dual vortex to separate coarse from fine dust. The main vortex spirals downward and carries most of the coarser dust particles. The inner vortex created near the bottom of the cyclone spirals upward and carries finer dust particles.
is a filtration device that removes fine particles, like dust and smoke, from a flowing gas using the force of an induced electrostatic charge. The charged particles are attracted to and deposited on plates or other collection devices. The collectors are shaken by suitable mechanisms to dislodge the accumulated dust , causing it to fall with the force of gravity to hoppers below. The dust is then removed by a conveyor system for disposal or recycling.
Wet scrubbers remove dust particles by capturing them in liquid droplets. The droplets are then collected, the liquid dissolving or absorbing the pollutant gases. Any droplets that are in the scrubber inlet gas must be separated from the outlet gas stream by means of another device referred to as a mist eliminator or entrainment separator. Also, the resultant scrubbing liquid must be treated prior to any ultimate discharge or being reused in the plant.
