Operation of the cyclone cyclone lower portion of rigor is another important factor affecting the collection efficiency. After the dust and gas into the cyclone, along the outer walls from top to bottom as the spiral rotary motion, after reaching the bottom of the cone, turned on, rotate upward along the axis of rotation which shares downward airflow. The pressure distribution within the cyclone, the smaller the pressure change in axial cross-section of each radial pressure vary widely (mainly static pressure), which is distributed by the axial air flow velocity and radial velocity determined. Airflow circular motion in the barrel, the inside pressure is higher than outside, the static pressure in the vicinity of the outer wall of the highest cyclone, the minimum static pressure at the axis. Even under positive pressure cyclone movement, the axial center is also negative, and has been extended to negative pressure at the maximum discharge of gray, a little tight, it will have a greater leakage, has been set down dust is bound to sink It raised flow out of the exhaust pipe. So, to make the collection efficiency to meet the design requirements necessary to ensure the tightness of the mouth of ash and ash port ensuring rigor and promptly remove dust filter cone at the bottom, if not continuously discharged in a timely manner, cyclone parameters, high concentrations of dust will be in the bottom of the circulation, leading to excessive wear cone. Effect of the exhaust pipe diameter and depth of the collection efficiency of the cyclone exhaust pipe diameter and insertion depth greater impact on the cyclone collection efficiency. Exhaust pipe diameter must select an appropriate value, the exhaust pipe diameter decreases, the rotation range may be reduced swirl of dust and difficult to discharge from the exhaust pipe, it is advantageous to improve collection efficiency, but also increases the speed of the outlet, cyclone Quotes, resistance loss increases; if the exhaust pipe diameter increases, although the pressure loss can be significantly reduced, but the exhaust pipe and the cylinder wall is too close, easy to form the inner and outer swirl "short circuit" phenomenon, the outer part of the cyclone is not cleared of dust mixed directly into the exhaust pipe discharge, thereby reducing the collection efficiency. Generally believed exhaust pipe diameter of 0.5 to 0.6 times the diameter of the cylindrical body is appropriate. Exhaust pipe inserted too shallow, could easily lead to dust stream inlet directly into the exhaust pipe, the impact of the collection efficiency; exhaust pipe is inserted deep, easy to increase airflow and wall friction surface, the new cyclone to increase the resistance loss big, same time, the exhaust pipe at the bottom of the cylinder and cone shorten the distance, increase the chance of dust discharged from the secondary back-mixing. Exhaust pipe is inserted into the bottom of the depth generally slightly lower than the position of the outlet is appropriate. Since the cyclone unit consumption of steel than the larger, so the design of a better approach is downward from the upper portion of the barrel material gradually decreases from thick to thin!
