Solution Overview
Problem
Existing suspension separation systems face challenges in predicting performance, optimizing efficiency, and reducing hydraulic inefficiencies due to scale differences and suboptimal hydraulic and flocculation efficiency, leading to increased costs and complexity in various industrial applications.
Innovation Solution
The Hydro-Gravitational Trap (HGT) apparatus separates suspensions into two flow streams using a receptacle with distinct kinetic energy segments, including a High-Energy Segment for particle trapping, a Transitional-Energy Segment for energy dissipation, and a Low-Energy Segment for particle separation, aided by an agitator for mixing and preventing particle adherence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing suspension separation devices are used, then separation function is provided, but hydraulic inefficiencies increase cost and reduce performance
Solution Approach 1:
The separation device is divided into three distinct segments with different kinetic energy characteristics: High-Energy Segment for particle trapping, Transitional-EnergySegment for energy dissipation, and Low-EnergySegment for particle separation. This segmentation allows each region to optimize its function while reducing overall hydraulic inefficiency
Solution Approach 2:
The device controls kinetic energy parameters through varying segment designs, transitioning from high kinetic energy at the inlet to low kinetic energy at the separation zone. This parameter change enables efficient particle separation while reducing energy loss compared to conventional single-zone devices
2Productivity
If large surface areas and volumes are used, then separation capacity is increased, but construction depth increases despite theoretical calculations
Solution Approach 1:
The device transitions from traditional vertical depth-based separation to a horizontal segmented approach. By organizing separation functions across horizontal segments rather than requiring deep vertical construction, the device achieves high separation capacity without increasing construction depth
Solution Approach 2:
Dividing the separation process into three functional segments allows each segment to be optimized for its specific purpose while maintaining a compact overall footprint. This segmentation enables high capacity separation without requiring proportionally large volumes or depths
3Reliability
If high safety factors are applied, then reliability is improved, but device complexity and cost increase
Solution Approach 1:
The device achieves reliable separation through controlled kinetic energy parameters and optimized flow characteristics in each segment, eliminating the need for excessive safety factors. The high-energy segment creates effective particle trapping through controlled turbulence, while the low-energy segment ensures complete separation, providing reliable performance without added complexity
4Productivity
If conventional separation methods are used, then suspension separation is achieved, but flocculation efficiency is suboptimal
Solution Approach 1:
The high-energy segment creates periodic turbulent flow patterns that promote effective flocculation of particles. This periodic action allows particles to collide and aggregate before entering the separation zone, improving flocculation efficiency while maintaining high separation performance

AI summary
The disclosed Hydro-Gravitational Trap (HGT) method and apparatus separate a suspension into two flow streams, discriminating particles based on a designated particle settling velocity: one Designated Particle Concentrated (DPC) and one Designated Particle Diluted (DPD). The HGT confines particles between a controlled upward hydrodynamic field and the downward net gravitational field within the apparatus's High-Energy Segment (HES), awaiting removal. The HES typically contains an internal agitator conforming to its divergent shape. Agitator motion prevents trapped particles from adhering to the HES, provides flocculation energy, and mixes the contents, controlling the DPC flow stream concentration. The agitator can also simultaneously function as a control valve or an actuator regulating this flow in some preferred embodiments. Designated particles remain trapped in the HES until removed with the DPC flow stream while the DPD flow stream advects upward, exiting the apparatus through the top of the Low-Energy Segment (LES).
