Solution Overview

Problem

Existing separator apparatuses are inefficient in separating gaseous matter from non-gaseous matter in effluent streams, often resulting in particles being ejected through the gas outlet and liquid being vented through the exhaust, which increases operational power requirements and reduces separation efficiency.

Innovation Solution

A rotor for a separator apparatus is designed with an annular skirt that defines a centrifugal separator with a gas outlet and a waste outlet. The surface of the annular skirt is angled towards the axis of rotation, biasing non-gaseous matter towards the waste outlet through centrifugal force, thereby improving separation efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a conventional separator apparatus is used, then the apparatus can treat effluent streams, but particles are ejected through the gas outlet and liquid is vented through the exhaust, reducing separation efficiency

Engineering Contradiction:
Improveseparation efficiencyVSAvoidparticles and liquid ejected through wrong outlets
Core Design Contradiction:
Manufacturing precisionVSObject-generated harmful factors

Solution Approach 1:

The patent changes the geometric parameter of the annular skirt surface by angling it towards the axis of rotation. This angular orientation creates a centrifugal force component that redirects non-gaseous matter toward the waste outlet, fundamentally altering the flow dynamics and separation efficiency of the apparatus.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The annular skirt surface is designed with an asymmetric angular inclination rather than a symmetric or vertical orientation. This asymmetric geometry creates uneven force distribution on the effluent stream, preferentially directing particles and liquid toward the waste outlet while allowing gas to exit through the gas outlet.

Inventive Principle:
Principle #4Asymmetry

2Use of energy by moving object

If liquid is ejected through the gas outlet, then the separator apparatus operates, but the liquid becomes trapped between the rotor and stator, increasing drag and power requirements

Engineering Contradiction:
Improvepower requirementsVSAvoidliquid trapped between rotor and stator
Core Design Contradiction:
Use of energy by moving objectVSObject-generated harmful factors

Solution Approach 1:

By changing the angular parameter of the annular skirt surface, the patent modifies the trajectory of liquid in the effluent stream. This prevents liquid from reaching the space between rotor and stator, eliminating the source of increased drag and subsequent power requirements.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The angled surface configuration proactively prevents liquid from being ejected toward the gas outlet in the first place. By establishing the correct flow direction at the separation interface, the design anticipates and prevents the harmful effect of liquid trapping before it occurs.

Inventive Principle:
Principle #9Preliminary anti-action

3Manufacturing precision

If the annular skirt surface is angled towards the axis of rotation, then non-gaseous matter is biased towards the waste outlet, but the device complexity increases

Engineering Contradiction:
Improveseparation efficiencyVSAvoidrotor structure complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent implements a single geometric parameter change - the angular orientation of the annular skirt surface. This straightforward parametric modification achieves improved separation without introducing complex mechanisms, multiple moving parts, or sophisticated control systems.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The angular orientation is applied locally to the annular skirt surface that contacts the effluent stream, rather than redesigning the entire rotor structure. This localized modification achieves the separation improvement while keeping the rest of the device simple and unchanged.

Inventive Principle:
Principle #3Local quality

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution effectively separates at least 80% of non-gaseous matter from the effluent stream, reducing the likelihood of particles exiting through the gas outlet and minimizing operational power requirements by reducing drag on the rotor.

Implementation Method 1
