Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional gas-liquid exchange devices (water film, dust catcher, humidifier) are used for mass exchange, then dust can be separated from gas, but energy consumption is huge and structure is complicated
Solution Approach 1:
The gas flow path is segmented into multiple stages by introducing gas blocking plates at different heights, creating multiple narrow passages that segment the gas-liquid contact process into sequential zones, improving separation efficiency while reducing energy consumption
Solution Approach 2:
The invention transitions from traditional horizontal gas flow to vertical gas flow through the gas blocking plates, utilizing the vertical dimension to create multiple contact zones and enhance mass exchange efficiency without increasing horizontal footprint
2Temperature
If traditional heat exchangers are used for energy exchange between gas and liquid, then energy exchange can be achieved, but device size is too large
Solution Approach 1:
The gas passage is nested within the liquid-filled vessel, with gas blocking plates nested at different vertical positions, creating a compact multi-stage exchange structure that achieves high energy exchange efficiency within a small volume
Solution Approach 2:
The gas blocking plates are designed to be movable rather than fixed, allowing dynamic adjustment of gas flow paths and contact zones to optimize energy exchange efficiency while maintaining a compact device size
3Quantity of substance
If traditional gas-liquid exchange devices are used, then mass exchange can occur, but structure is complicated
Solution Approach 1:
The gas blocking plates serve multiple functions simultaneously: they block gas flow to create narrow passages, provide support for liquid droplets, and act as spacing elements for multiple contact zones, reducing overall structural complexity while maintaining high mass exchange efficiency
Solution Approach 2:
The invention merges the gas blocking function and liquid support function into a single integrated structure, eliminating the need for separate components and simplifying the overall device structure while maintaining effective mass exchange

Implementation Method 1
forming fast gas flow in the narrow passage due to the blocking of the gas blocking plate; bringing the liquid to leave the liquid surface and spray to the space in the gas passage to form a liquid curtain and liquid droplets by fast gas flow
Implementation Method 2
making a portion of liquid droplets move with the gas flow; making the gas flow contact with the liquid sufficiently and achieving the energy and mass exchange between gas phase and liquid phase
Implementation Method 3
separating the liquid droplets from the gas flow and making the liquid droplets fall into the liquid surface due to the cavity thereof after moving a certain distance
