How is cyclone separator calculated?
FINAL DESIGN:
- Diameter of cyclone = Dc = 0.063 m.
- Flow inlet area =0.5Dc*0.2Dc = 4*E-4 m2.
- Cylindrical length = 1.5 Dc = 0.0945 m.
- Conical section ht. =2.5Dc = 0.1575 m.
- Conical end diameter=0.375Dc = 0.0236 m.
- Outlet diameter = 0.5Dc = 0.0315 m.
- Collecting Hopper diameter =Dc =0.063 m.
What would be the efficiency of cyclone separator?
Effectiveness. Cyclone separators are generally able to remove somewhere between 50-99% of all particulate matter in flue gas.
What is separation efficiency?
Separation efficiency is defined as the ratio of concentration that has been removed from the feed stream to the initial concentration in the feed stream, shown in Eq. (1). From: Computer Aided Chemical Engineering, 2016.
How do you calculate pressure drop in a cyclone?
The solution of the equation 3 is: P = D* Vt * ln (r) + C (4) This solution gives the pressure distribution in the cyclone flow field. The cyclone pressure drop is a function of the cyclone dimensions and its operating conditions.
What is pressure drop in cyclone separator?
Pressure drop is one of the important indexes of the performance of cyclone separators. It is mainly caused by the friction between the fluid and the wall and the internal vortex flow. (5) As the mass loading of particles will affect the pressure drop, all pressure drops are measured with particle loading.
Which cyclone separator has greater efficiency one with a smaller diameter or larger one?
The primary design factor that controls collection efficiency is cyclone diameter. A small-diameter unit operating at a fixed pressure drop has a higher efficiency than a large-diameter unit.
How many dimensions does a cyclone separator have?
1. Schematic diagram for Stairmand cyclone separator. While the cyclone geometry is simple, the flow is extremely complicated three dimensional swirling flow. The complexity of the gas solid flow pattern in cyclones has long been a matter of many experimental and theoretical works.
How do you calculate separation factor?
What is separation factor? The general definition of this number is the ratio of the center to center distance divided by the sum of the ellipses radii.
What is the pressure drop range of cyclone?
Pressure drop was recorded for inlet velocities from about 10 to 20 m s− 1. The radial evasé reduced cyclone pressure drop by between 8.7 and 11.9 percent when its exit area was equal to the flow area of the cyclone vortex finder or gas exit.
How do you calculate pressure in a cyclone?
What is working principle of cyclone separator?
Working principle A cyclone is a centrifugal separator in which particles, due to their mass, are pushed to the outer edges as a result of centrifugal force. Incoming air is automatically forced to adopt a fast-revolving spiral movement – the so-called “double vortex”.
What is the inlet velocity in cyclone separator?
The design inlet velocity for the 1D3D cyclone is 16.26 ± 2.03 m s− 1 [10], [11], corresponding to a Stokes number of 1.4 for PM2.5 in the conditions tested.
What is the minimum pressure required for a cyclone separator?
Pressure is also a necessity for proper operation of a cyclone separator. The minimum pressure differential must be around 20 psi/1.4 bar between the suction and discharge. This could be the most crucial aspect of having the separator function properly.
What is a cyclone separator?
Cyclone separators range in design from a unitary simple construction to a more complex design that uses gaskets, bolts and multiple parts. The cyclone separator discussed in this article is a one-piece design that uses its simple construction to allow for low temperature, low costs and clean flow rates.
How do you calculate the diameter of a cyclone?
Diameter of cyclone = Dc = 0.063 m Flow inlet area =0.5Dc*0.2Dc = 4*E-4 m2 Cylindrical length = 1.5 Dc = 0.0945 m Conical section ht.=2.5Dc = 0.1575 m
How can cyclone abrasive separators improve seal life?
The ability to increase the life of a mechanical seal can be as easy as adding one simple design element to the equipment. Cyclone abrasive separators provide an effective way to keep solids found in liquids from contaminating and damaging mechanical seal faces. They can also help improve the seal life and reduce maintenance costs.
