Area of Science:

• Fluid dynamics
• Chemical engineering
• Separation technology

Background:

• Hydrocyclone separators are crucial in industrial processes but suffer from high energy consumption.
• Optimizing hydrocyclone design is essential for improving efficiency and reducing operational costs.

Purpose of the Study:

• To investigate the impact of a novel slotted overflow pipe on hydrocyclone performance.
• To determine the optimal parameters for the slotted overflow pipe structure.
• To reduce the energy consumption of the hydrocyclone separation process.

Main Methods:

• Experimental investigation using response surface optimization.
• Design and testing of a novel slotted overflow pipe structure.
• Computational Fluid Dynamics (CFD) simulations to analyze internal flow dynamics.

Main Results:

• Optimal parameters identified: three layers of slots, 5.3 mm positioning dimension, and 58° slot angle.
• Validated experiments show a 0.26% increase in separation efficiency and a 24.88% reduction in pressure drop at 900 ml/s.
• CFD simulations confirmed reduced internal flow velocity and pressure drop with the slotted structure.

Conclusions:

• The slotted overflow pipe is an effective modification for enhancing hydrocyclone efficiency.
• This design significantly reduces pressure drop, leading to lower energy consumption.
• Provides a valuable reference for designing energy-efficient hydrocyclone separators.
