Solution Overview
Problem
Flue gas purification systems face challenges in adaptability due to variations in gas and absorbent qualities, quantities, velocities, and other process parameters, leading to inefficient gas purification processes that fail to meet economic and ecological demands.
Innovation Solution
A wet scrubber tower with a scrubber tray featuring pivot-mounted spindles and plate-like protrusions that can be rotated to adjust the flow-through area, allowing for varying sizes and shapes of flow-through openings to optimize the transfer area between gas and liquid, thereby adapting to different process conditions with minimal power and force requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the scrubber tray uses fixed flow-through openings, then the structure is simple and reliable, but the gas purification process cannot adapt to variations in gas quantity, quality, and velocity
Solution Approach 1:
The scrubber tray incorporates rotatable spindles with plate-like protrusions that can be rotated to different positions, transforming the fixed structure into a dynamic one. This allows the flow-through opening area to be adjusted according to varying process parameters such as gas quantity, quality, and velocity, directly resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The invention enables change of the geometric parameters of the tray by rotating the spindles to different angular positions. This alters the flow-through opening area and the contact area between gas and liquid, allowing optimization of the purification process for different operating conditions without changing the basic tray structure.
2Productivity
If the flow-through opening area is increased to handle higher gas volumes, then the gas velocity decreases and contact time is reduced, but the transfer area between gas and liquid is also reduced
Solution Approach 1:
The invention allows dynamic adjustment of two critical parameters: the flow-through opening area (affecting gas velocity and contact time) and the liquid distribution pattern (affecting transfer area). By rotating the spindles, both parameters can be optimized simultaneously for different gas volumes, resolving the contradiction between productivity and purification efficiency.
3Manufacturing precision
If traditional trays with fixed geometry are used, then the device is simple to operate, but the contact area between gas and liquid cannot be optimized for varying process conditions
Solution Approach 1:
The rotatable spindles provide a simple mechanical means to adjust the contact area and flow patterns. The rotation mechanism is straightforward, requiring minimal operational complexity while enabling precise optimization of the gas-liquid contact area for different process conditions, thus resolving the contradiction between manufacturing precision and ease of operation.
4Adaptability or versatility
If the scrubber tray is designed with adjustable components to optimize purification, then the power and force requirements for adjustment increase
Solution Approach 1:
The tray is segmented into multiple independent spindles that can be rotated individually or in groups. This segmentation allows localized adjustment without requiring high power to move the entire tray structure, reducing the activation power requirement while maintaining purification optimization capability.
Solution Approach 2:
The rotational adjustment mechanism uses simple mechanical advantages to achieve position changes with minimal force. The spindles can be rotated to different angular positions using small torques, enabling adaptability without significant power consumption.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances the adaptability and efficiency of the gas purification process by optimizing the contact area between gas and liquid, improving the degree of purification and reducing energy consumption through easy adjustment of the scrubber tray's geometry.
Implementation Method 1
the liquid absorbent is temporarily stored onto the tray and a liquid bath formed, the flue gas, penetrating the liquid bath upwardly, gets into intimate contact with the absorbing liquid
Implementation Method 2
the type of the liquid absorbents is not decisive as far as it absorbs and/or chemically interacts with the various components/impurities of the flue gas, such as sulphur oxides and CO2
