Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carbon capture systems suffer from uneven distribution of exhaust gas, leading to insufficient absorption of chemical components like carbon monoxide and carbon dioxide due to concentrated gas streams.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If exhaust gas flows through a simple flow guiding tube, then the structure is simple, but the exhaust gas flows as a concentrated stream and is not evenly dispersed
Solution Approach 1:
The flow guiding device is divided into multiple functional units: a flow guiding unit with a guiding member that defines a flow channel, a stabilizing unit with a stabilizing member that defines a stabilizing space, and multiple gas outlet holes. This segmentation allows each component to perform its specific function in sequence, transforming the concentrated gas stream into evenly distributed flow without requiring complex external systems.
Solution Approach 2:
The stabilizing member is disposed inside the flow guiding member, with the stabilizing space formed within the flow channel. This nested configuration allows the stabilizing unit to be integrated within the flow guiding unit, achieving flow stabilization without adding external components or increasing overall device complexity.
2Speed
If exhaust gas flows as a concentrated stream, then the flow path is direct, but the contact area with absorbent is insufficient and absorption efficiency is low
Solution Approach 1:
The gas outlet holes are arranged in multiple dimensions within the stabilizing member, including different orientations and positions. This multi-dimensional arrangement disperses the gas flow in multiple directions simultaneously, dramatically increasing the contact area with the absorbent in the chamber and improving absorption efficiency while maintaining direct flow paths.
3Length of moving object
If exhaust gas flows directly into the chamber, then the flow path is short, but the reaction time with absorbent is insufficient
Solution Approach 1:
The flow guiding unit and stabilizing unit perform preliminary actions on the gas flow before it enters the chamber. The guiding member straightens and distributes the flow, while the stabilizing member further disperses it through multiple gas outlet holes. This preliminary conditioning ensures that when the gas enters the chamber, it is already in an optimal state for maximum contact with the absorbent, effectively extending reaction time without lengthening the physical flow path.
4Stability of the object's composition
If a flow guiding device with multiple units is used, then gas distribution is even, but the device complexity increases
Solution Approach 1:
The flow guiding unit and stabilizing unit are integrated into a single compact device, with the stabilizing member nested within the flow guiding member. The communicating member connects both units and integrates their functions. This merging achieves uniform gas distribution through multiple functional elements while maintaining a simple overall structure that does not require separate external components.
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 ensures even distribution of exhaust gas, enhancing absorption efficiency by increasing contact area and reaction time with the scrubber, thereby improving the removal of chemical components.
Implementation Method 1
The gas rectifier is disposed at an end portion of the main housing that is opposite to the communicating member, and has a plurality of air holes adapted for dispersing the exhaust gas passing therethrough to enter the scrubbing module
Implementation Method 2
The absorbent is in contact with the exhaust gas introduced into the chamber 93 to absorb chemical components such as carbon monoxide and carbon dioxide in the exhaust gas
Implementation Method 3
most absorbents available on the market are made of a porous material in a solid form that absorbs chemical components through Van der Waals forces or strong covalent resultant forces when being in contact with the exhaust gas

AI summary
A flow guiding device for a carbon capture system includes a connecting unit and a flow guiding unit connected to the connecting unit. The connecting unit includes a communicating member defining a gas flow channel, a main housing diverging gradually from the communicating member, and a gas rectifier disposed opposite to the communicating member and having a plurality of air holes. The flow guiding unit includes a guiding member defining an flow channel in fluid communication with the gas flow channel and having a plurality of through holes in fluid communication with the flow channel, a main body diverging gradually from the guiding member, and a flow disturbing member disposed at a terminal portion of the main body and having a plurality of flow distributing holes. The main body cooperates with the main housing to define an annular flow channel therebetween that is in fluid communication with the through holes.
