Cyclone dust trap down the smaller particle size, the higher the collection efficiency of the precipitator. The size of the centrifugal force and dust particles related to the larger particles, the greater the centrifugal force. When the dust particle size and greater tangential velocity, radial velocity and the exhaust pipe diameter of more hours, the effect of dust as possible. Gas concentration of ash is also a key factor in the impact of export concentration. When the dust concentration increases, the dust is easy to unite, unite together so that the smaller dust particles and captured, while the large particles to the walls of the move will also entraining small particles to hit the wall or be separated. However, due to the high-speed rotation within the air filter so that the pressure at the top of the drop, part of the flow will mix the fine dust particles along the outer wall to the top of the rotated upward, downward discharge from the exhaust pipe along the outer wall of the exhaust pipe is rotated, resulting in collection efficiency of the cyclone is unlikely to be 100 percent. Collection efficiency is calculated according to η = (1- So / Si) × 100%, where, η-- collection efficiency; inflows So-- dust at the outlet, kg / h; dust at the inlet Si-- The inflows, kg / h. Dust particle size is a key factor affecting export concentration. In cyclone dust swirling outside, in the radial direction while being the role of the two forces, one centrifugal force generated by the rotating air flow generated by the tangential velocity, so that the role of dust by the passage of outwardly; the other is by the rotating airflow centripetal force generated by the radial velocity, so that the dust by the passage of the role of inward. Including, at the junction of the outer surface of the cyclone, the centrifugal force if tangential velocity is greater than the centripetal force generated by the radial velocity, then move to the outer wall of dust under the centrifugal force of inertia driven so as to be separated; centrifugal force generated if tangential velocity centripetal force generated by less than the radial velocity, the dust enters the cyclone at a centripetal force push, finally discharged through the exhaust pipe. If the centrifugal force generated by the tangential velocity equal to the centripetal force generated by the radial velocity, that is acting on the dust particles of force equal to zero, in theory, the dust should be spinning at the interface. In fact due to the impact of turbulent air flow in the state and a variety of random factors in this state there is a 50% chance of dust into the cyclone, there is a 50% chance to move to the outer wall, the collection efficiency should be 50%. At this critical dust particle separation as a dividing particle size. In this case, the inner and outer swirling flow pore size of the interface as a screen divided particle size, the particle size of dust is larger than the split screen and trap trapped down, the dust particle size of less than divided, through the screen discharged from the exhaust pipe. Because the collection efficiency of the cyclone is unlikely to be 100 percent, when imports increased inflows of dust, dust removal efficiency, are improved dust exhaust pipe absolute amount will be greatly increased. Therefore, the dust concentration is reduced to make the discharge port, will have to reduce the inlet dust concentration, can take more than one cyclone dust used in tandem multi-stage manner to achieve the purpose of reducing emissions.
