Solution Overview

Problem

Existing separators for gas and particle removal from liquids, such as in heating and cooling systems, require a large form factor and have limited efficiency, necessitating a more compact and efficient design.

Innovation Solution

A separator design featuring a collection chamber with a main fluid flow path containing a separating element, such as a spiraling wire structure, and a secondary fluid flow path defined by plates that bypass the separating element, allowing for enhanced bubble growth and particle separation, with the plates positioned to align and relax the flow, reducing turbulence and increasing separation efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the volume of the collection chamber is increased to effectively separate gas and particles from liquid, then separation efficiency is improved, but the form factor of the separator increases

Engineering Contradiction:
Improveseparation efficiencyVSAvoidcollection chamber volume
Core Design Contradiction:
ProductivityVSVolume of stationary object

Solution Approach 1:

The collection chamber is divided into multiple flow paths (first fluid flow path through separating elements and second fluid flow path bypassing separating elements), allowing the chamber to handle larger volume flows without increasing overall volume. This segmentation enables parallel processing of fluid streams, improving separation efficiency while maintaining compact dimensions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention introduces a bypass flow path that operates in parallel to the main separation path, effectively adding a dimensional aspect to the flow configuration. This allows the system to process larger volumes without increasing the vertical or horizontal footprint, resolving the contradiction between separation efficiency and form factor.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Volume of stationary object

If the collection chamber volume is reduced to achieve a smaller form factor, then compactness is improved, but separation efficiency deteriorates

Engineering Contradiction:
Improvecollection chamber volumeVSAvoidseparation efficiency
Core Design Contradiction:
Volume of stationary objectVSProductivity

Solution Approach 1:

By segmenting the flow into multiple paths within the compact chamber, the invention maintains adequate residence time and separation effectiveness despite the reduced overall volume. The separating elements in the first flow path continue to function effectively while the second flow path accommodates bypass flow, preserving separation efficiency in a compact form.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention changes the flow distribution parameters by introducing a bypass path that handles a portion of the volume flow. This parameter change allows the compact chamber to maintain optimal flow velocities and residence times for separation, preventing efficiency deterioration despite volume reduction.

Inventive Principle:
Principle #35Parameter changes
