Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas and dirt removal devices in liquid conduit systems are inefficient in reducing liquid velocity and settling particles, particularly for heavy contaminating liquids, leading to clogging and damage, and are often too large and costly for practical use.
Innovation Solution
A compact removal device with separate quiet zones for dirt and gas removal, utilizing a unique flow pattern with bifurcation and merge points to create low-velocity areas for effective particle settling, and a resistance zone to manage hydrostatic pressure, allowing for efficient removal of both heavy and light contaminating liquids without the need for vaporization chambers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the size of the quiet zone is increased to allow dirt particles to settle, then the settling effectiveness is improved, but the device size becomes impractically large
Solution Approach 1:
The device divides the flow path into multiple segments with different functions: a first quiet zone for dirt removal, a resistance zone for velocity reduction, and a second quiet zone for gas removal. This segmentation allows each zone to be optimized for its specific purpose while keeping the overall device compact.
Solution Approach 2:
The device utilizes vertical dimension by arranging zones at different heights - the first quiet zone and resistance zone are positioned below a horizontal partition, while the second quiet zone is positioned above the partition. This three-dimensional arrangement maximizes functional capacity within a limited footprint.
2Reliability
If the liquid velocity is reduced to allow particles to settle, then the particle settling is improved, but the flow resistance increases
Solution Approach 1:
The resistance zone is strategically positioned between the first and second quiet zones to create localized velocity reduction only where needed for particle settling, while maintaining higher velocities in other sections to minimize overall flow resistance and energy loss.
3Reliability
If a separate gas removal device and dirt removal device are used, then the removal effectiveness is improved, but the cost and complexity increase
Solution Approach 1:
The device combines dirt removal and gas removal functions into a single integrated unit. The first quiet zone handles dirt particle settling, while the second quiet zone handles gas bubble removal, both within one device structure, eliminating the need for separate devices.
Solution Approach 2:
The device performs multiple functions simultaneously: removing dirt particles, removing gas bubbles, and reducing liquid velocity. The horizontal partition and associated outlets enable the device to handle both heavy contaminating liquids (dirt) and light contaminating liquids (gas) through different mechanisms.

AI summary
The present invention relates to a removal device for removing gas and/or dirt and/or particles from a contaminating liquid from a liquid in a liquid conduit system, the removal device comprising: - a housing which defines an inner space, - a supply opening and a discharge opening, - a resistance zone comprising an entrance and an exit and one or more flow resistance members, which resistance zone in use provides a hydraulic resistance to a main flow which flows from the supply opening through the resistance zone to the discharge opening, - at least one quiet zone in the inner space in which in use the liquid has a substantially smaller velocity than in the resistance section, the quiet zone being configured to allow: a) dirt and/or particles of a relatively heavy contaminating liquid to settle to a bottom of the housing, and/or b) gas bubbles and/or particles of a relatively light contaminating liquid to rise to an upper end of the housing - at least one bifurcation opening in the resistance zone, the bifurcation opening being in liquid communication with the quiet zone and providing entry for a branch-off flow into the quiet zone, - at least one return opening between the quiet zone and a merge point in the main flow upstream and/or downstream from the resistance zone, such that in use the branch-off flow enters the quiet zone through the bifurcation opening, substantially comes to rest in the quiet zone in order to allow dirt and/or particles of a relatively heavy contaminating liquid to settle or gas bubbles and/or particles of a relatively light contaminating liquid to rise and subsequently returns into the main flow at the merge point through the return opening.
