The high-efficiency coal powder separator air classifier is part of coal mill system and coal coal feeding system in power and cement plant. It has the characteristics of economical and practical, simple and compact structure, easy installation and convenient maintenance. The air volume of the powder separator is generally 33,000-38000 m3/h.
The coarse powder separator and the fine powder separator form a swirling airflow after the dustenters the volute of the cyclone from the inlet. Due to the different quality of the dust and air, the dust materialdeflected toward the wall of the cyclone due to the centrifugal force, along the wall of the cylinder. Falling into the cone, and the gas of the clean body is discharged into the atmosphere along the inner wall of the cyclone through the exhaust pipe.
Size 3 Pfisterer MV-CONNEX inner cone plug, without voltage tap facility. Each kit is size-sensitive and supplied to suit a specific conductor size and limited insulation diameter range. Please provide full constructional and dimensional information for the cable/s being used to ensure compatibility of the proposed cable/connector arrangement.
Fully screened, touch-proof Pfisterer connectors feature a silicone rubber stress control component, within an aluminium bell housing and sealant-lined heatshrink tube to protect against moisture ingress. Supplied in sets of three phases.
Performance of a hydrocyclone can be influenced by many factors, such as structural type, geometric parameters and operation parameters, among which the structural type plays a very important role. The separation principle of a typical hydrocyclone was introduced. Focused on a gasliquid separation, numerical simulation of the typical hydrocyclone was carried out. The gas phase fraction distribution was analysed. It is shown that the separation effect was not satisfactory. A revising idea was thus proposed and developed step by step, so a new inner-cone hydrocyclone (ICH) was designed. The inner-cone structure was thought to provide a more stable flow field for phase separation. It functions like a gas carrier that is beneficial for radially separated gas congregating on and growing into larger gas bubbles. It also produces an upward pushing force to gas bubbles, so as to enhance the gasliquid separation performance, although the ICH has lower inner tangential velocities than the typical hydrocyclone. Numerical simulation and experimental study verified the analysis. Pressure drop of the ICH is much lower than that of the typical hydrocyclone; and the ICH has a wider scope for the change of liquid split ratio or inlet gasliquid ratio. Development of the ICH would provide a new thought for the design of other separators.
The typical hydrocyclone might not get a satisfactory efficiency for a gasliquid separation. We describe the design idea and procedure of a new inner-cone hydrocyclone (ICH). The new ICH does enhance the gasliquid separation theoretically and practically. The new ICH has a lower pressure drop compared with that of the typical hydrocyclone. The inner-cone design would provide a new idea for separator design.
The aerodynamics within a reduced scale model of a vertical spindle coal mill static classifier are investigated to provide data for improving classifier particle separation predictions and the validation of computational simulations. Quantitative data for these purposes was obtained by measuring velocities using three-dimensional Laser Doppler Anemometry. Flow visualisation was also used to provide qualitative understanding. The results demonstrate that the flow in the main classifier volume closely resembles that reported in the literature for cyclones. However, the flow in the upper section of the classifier is highly three-dimensional. The effect of varying the inlet vane angle, within the range of industrially useful vane angles, is shown to principally only affect the tangential velocity magnitude.Get in Touch with Mechanic
