Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exhaust gas purification devices are large, complex, and primarily designed for single pollutant removal, making them inefficient and costly for addressing the increasing environmental standards and the need to remove multiple pollutants from industrial waste gases, such as nitrogen oxides and volatile organic compounds.
Innovation Solution
A gas phase oxidation/decomposition and absorption integrated device that combines plasma technology with supergravity technology, featuring a rotating chamber and a discharge chamber with a plasma generator, where a gas-liquid countercurrent contact occurs under centrifugal force, enhancing mass transfer and oxidation/decomposition of pollutants like NO and volatile organic compounds into non-polluting species like NO2 or CO2.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional single pollutant removal devices are used, then removal function is provided, but device area and process complexity increase
Solution Approach 1:
The patent combines multiple pollutant removal functions (desulfurization, denitrification, VOC removal) into a single integrated device by incorporating multiple reaction chambers with different catalytic functions. The first reaction chamber handles sulfur oxides, the second handles nitrogen oxides, and the third handles volatile organic compounds, all within one unified system that shares common structure and control mechanisms.
Solution Approach 2:
The device achieves multi-functionality by equipping different reaction chambers with specific catalytic materials tailored for different pollutant types. The system can simultaneously or sequentially remove multiple pollutants from exhaust gas through a single integrated process flow, eliminating the need for separate treatment devices for each pollutant type.
2Adaptability or versatility
If multiple separate purification devices are deployed, then comprehensive pollutant removal is achieved, but occupied area increases
Solution Approach 1:
The patent vertically stacks multiple reaction chambers (first, second, and third reaction chambers) within a single device housing, allowing multiple pollutant removal functions to be compacted into one footprint. The chambers are arranged in series along the gas flow path, enabling comprehensive treatment without requiring multiple separate horizontal units.
3Productivity
If conventional gas-liquid reactors are used, then reaction occurs, but mass transfer efficiency and reaction conversion rate are insufficient
Solution Approach 1:
The patent replaces conventional mechanical gas-liquid contactors with a plasma-based reaction system. Plasma generates highly reactive species (electrons, ions, radicals) that directly interact with pollutants, eliminating the need for traditional mass transfer-limited gas-liquid interfaces and significantly enhancing reaction conversion rates.
Solution Approach 2:
The patent changes the fundamental reaction parameters by introducing plasma energy to create a non-thermal environment with highly reactive species. This transforms the reaction mechanism from conventional thermal or catalytic processes to plasma-driven reactions, achieving superior mass transfer and conversion efficiency.
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 high removal efficiency and mass transfer rates for nitrogen oxides and volatile organic compounds, reducing pollution and operational costs while occupying a smaller space, thus offering economic, environmental, and social benefits.
Implementation Method 1
The plasma is the fourth state of matter in addition to solid state, liquid state, and gaseous state, which is an aggregated-state substance. The high-energy electrons of the plasma would undergo a series of elementary reactions when colliding with gas molecules, and produce a variety of active free radicals, high-energy electrons, ecological oxygen, etc during the reactions.
Implementation Method 2
These high-energy electrons, free radicals and other active particles would interact with various pollutants in the gas so as to oxidize and decompose them in a very short time. For example, harmful substances such as NO in the flue gas or benzodiazepines in the volatile organic compounds are oxidized and decomposed into easily-removed NO2 or CO2 without pollution properties.
Implementation Method 3
In the process of realizing the gas-liquid system reaction, the traditional gas-liquid reactor had the disadvantages of low mass transfer efficiency and insufficient reaction conversion rate.
