Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If high-energy electron accelerators are used to achieve effective transmission depth, then the electron beam transmission depth is improved, but the equipment size and installation cost are increased
Solution Approach 1:
The housing is designed to rotate around the electron beam generation unit, dynamically changing the position of the transmissive part relative to the flue gas flow. This allows low-energy electron beams to effectively treat large volumes of flue gas through rotational movement, eliminating the need for high-energy accelerators and large equipment size
Solution Approach 2:
The invention adds temporal dimension through rotation, transforming a static single-point electron beam emission into a dynamic multi-position treatment system. The housing rotates to expose different sections of the flue gas stream to the electron beam over time, achieving volumetric treatment without increasing beam energy or equipment size
2Length of stationary object
If high-energy electron accelerators are used to achieve effective transmission depth, then the electron beam transmission depth is improved, but the installation cost is increased
Solution Approach 1:
Instead of increasing beam energy parameters, the invention changes the operational parameters by introducing rotation speed and angular position variables. Low-energy electron beams (0.1-10 MeV) are used with the housing rotating at controlled speeds to achieve effective treatment, significantly reducing accelerator cost while maintaining transmission effectiveness
Solution Approach 2:
The rotating housing structure allows the system to self-adjust the electron beam distribution across the flue gas stream. The rotation automatically ensures comprehensive coverage without requiring complex control systems or high-energy beams, reducing both manufacturing and installation costs
3Device complexity
If conventional electron beam emission is used, then the equipment structure is simple, but the process capacity is reduced due to non-uniform emission and dead zones
Solution Approach 1:
The rotating housing transforms a static single-point emission system into a dynamic distributed emission system. As the housing rotates, the electron beam continuously scans across different positions in the flue gas stream, eliminating dead zones and ensuring uniform treatment throughout the gas volume while maintaining simple equipment structure
Solution Approach 2:
The rotating housing structure serves multiple functions simultaneously: it positions the transmissive part to expose different gas streams to the electron beam, distributes the electron beam energy uniformly across the treatment volume, and prevents dead zone formation. This multi-functionality increases process capacity without significantly complicating the equipment
