Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas separation devices in plumbing systems suffer from poor gas separation efficiency due to uneven centrifugal forces and non-linear vortex alignment, leading to inefficient gas discharge and increased installation costs when multiple devices are used.
Innovation Solution
A device with a housing containing a gas discharge chamber, separation chamber, and central cylinder with spiral blades, where liquid is divided into streams by spiral blades, creating uniform centrifugal forces and a linearly aligned vortex, enhancing gas separation efficiency through a blocking member that separates gas from liquid before discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an eccentrically offset inlet is used to tangentially introduce water flow and create a vortex, then gas separation is achieved through centrifugal force, but the liquid undergoes uneven circumferential forces and the vortex rotational center is non-linearly aligned, causing gas to gather at the center in a distorted manner rather than converging in a straight line, which significantly diminishes the centrifugal effect and leads to poor gas separation efficiency
Solution Approach 1:
The inlet structure is segmented into multiple inlet ports distributed around the circumference, each introducing liquid flow at different angular positions. This segmentation allows the liquid to enter more uniformly and creates a more symmetric vortex pattern, improving gas separation efficiency while maintaining structural simplicity
Solution Approach 2:
The patent uses an asymmetric internal flow channel design within the housing that guides the liquid flow to create a controlled vortex pattern. The asymmetric channel geometry directs the liquid to rotate around a linearly aligned central axis, ensuring gas converges in a straight line at the center while still achieving effective centrifugal separation
2Productivity
If multiple gas separators are arranged in series to maximize gas discharge, then gas separation efficiency is improved, but installation costs and space requirements increase
Solution Approach 1:
Multiple gas separation functions are merged into a single integrated device. The housing contains both the vortex generation chamber and the gas discharge chamber in a unified structure, allowing the device to achieve high gas discharge efficiency while occupying minimal installation space, eliminating the need for multiple separate separators
3Productivity
If multiple inlets are incorporated on a housing to improve gas separation, then gas separation efficiency is enhanced, but pipeline connections become complicated
Solution Approach 1:
The single inlet structure is designed to perform multiple functions: it introduces liquid flow, generates vortex motion, and directs flow through the separation chamber. This multi-functional inlet design achieves effective gas separation while maintaining simple pipeline connections, avoiding the complexity of multiple inlet ports
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 device achieves improved gas separation efficiency by ensuring gases converge linearly and are effectively discharged, reducing the likelihood of gas escape, while minimizing installation height and space requirements.
Implementation Method 1
Gas-containing liquid is introduced through the liquid inlet interface pipe into the separation chamber, where the gas-containing liquid is divided into multiple streams by the spiral blades and spirals downward along the liquid passage channels between the central cylinder and the housing, generating tangential centrifugal forces during the spiral motion
Implementation Method 2
when the vortex-state liquid encounters the blocking member before entering the liquid outlet interface pipe, a sidewall of the blocking member causes the vortex-state liquid to split into: peripheral liquid, which is located outside the blocking member, and cavity liquid, which is located inside the concave cavity of the blocking member
Implementation Method 3
allowing gases to converge in a linear manner at the center of the vortex and ascend into an inner cavity of the central cylinder and then enter the gas discharge chamber
