Component Specifications

Definition
The conical section is a critical component of a cyclone separator, typically positioned below the cylindrical body. This tapered geometry accelerates the downward spiral of the gas stream, increasing centrifugal force to enhance the separation of solid particles or liquid droplets from the carrier gas. It facilitates the collection of separated material at the apex (dust hopper).
Working Principle
It operates on the principle of converting the tangential velocity of the incoming gas-particle mixture into a downward, accelerating spiral. The reducing cross-sectional area increases the angular velocity, thereby amplifying centrifugal forces that throw particles toward the wall. The particles then slide down the inclined wall into the collection chamber, while the cleaned gas reverses direction and exits upward through the central vortex finder.
Materials
Commonly constructed from carbon steel (e.g., ASTM A36), stainless steel (e.g., 304, 316 for corrosion resistance), abrasion-resistant steel, or lined with ceramic/polyurethane for high-wear applications. Material selection depends on process temperature, corrosiveness, and abrasiveness of particles.
Technical Parameters
  • Cone Angle Typically 10-20 degrees
  • Pressure Drop 500-2000 Pa
  • Inlet Velocity 15-30 m/s
  • Efficiency Range 70-99% for particles >5-10 μm
  • Standard Diameter Ratios Cone length to cylinder diameter ~1.5-2.5
Standards
ISO 14284, DIN 24100

Frequently Asked Questions

What is the primary function of the conical section in a cyclone?

Its primary function is to accelerate the gas stream to increase centrifugal force for more efficient particle separation and to guide separated solids into the collection hopper.

How does cone angle affect cyclone performance?

A steeper cone angle (smaller angle) generally increases collection efficiency for fine particles but may raise pressure drop. The optimal angle balances efficiency, pressure loss, and space constraints.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
