Advanced Solid-Liquid Separation: Horizontal Decanter Centrifuge for Global Environmental Projects

1. Equipment Overview & Core Structure

The Horizontal Decanter Centrifuge is a high-end environmental separation system that utilizes centrifugal force to achieve continuous solid-liquid separation. It is widely deployed in global wastewater treatment, petrochemical processing, food production, and mining engineering.

Core Structural Components

2. Working Principle – Detailed Explanation

2.1 Four-Step Continuous Separation Process

Step 1: Feed Acceleration
Slurry enters the rapidly rotating bowl via the feed tube and instantly stratifies under a high centrifugal field (1,500–4,000 G).

Step 2: Solid Sedimentation
Denser solid particles settle against the inner wall of the bowl, forming a compact solids ring; the lighter liquid forms an inner clarified layer.

Step 3: Spiral Conveying
The scroll, operating at a controlled differential speed (2–50 rpm), continuously pushes the settled solids toward the conical end for discharge.

Step 4: Liquid Overflow
Clarified liquid flows axially along channels between scroll flights toward the cylindrical end and exits through adjustable weir plates.

8. Technical Selection Guide

8.1 Essential Process Data Required

☑ Material type & source (detailed composition)
☑ Required capacity (m³/h or tons dry solids/day)
☑ Feed solids concentration (% w/w or mg/L)
☑ Particle size distribution (d10/d50/d90)
☑ Solid-liquid density difference (g/cm³)
☑ Feed temperature & pH
☑ Target cake moisture (%)
☑ Liquid clarity requirement (SS removal rate)
☑ Installation environment (indoor/outdoor/hazardous area)
☑ Altitude & power supply specifications

8.2 Key Sizing Formulas

Separation Factor (G):
$$ G = frac{r cdot omega^2}{g} = frac{r cdot (2pi n / 60)^2}{9.81} $$
Where:

• ( G ): Separation factor (dimensionless)
• ( r ): Bowl radius (m)
• ( n ): Rotational speed (rpm)
• ( g ): Gravitational acceleration (9.81 m/s²)

Capacity Estimation:
$$ Q = k cdot D^2 cdot L cdot G^{0.5} cdot frac{Deltarho}{mu} $$
Where ( k ) is a material-specific coefficient determined by lab testing.
