Engineering Contradiction Analysis
1Ease of manufacture
If traditional mixing units with stacked plates and orifice plates are used, then gas mixing is achieved, but the device becomes very bulky and requires excessive space
Solution Approach 1:
The invention extracts and eliminates the bulky stacked plate structure and orifice plate from the mixing system, retaining only the essential mixing function through a simplified gas stream perturbation device with inclined blades that achieves effective mixing without the excessive space requirements of traditional designs
Solution Approach 2:
The invention creates a simplified version of the mixing function using inclined blades on a rotating element that replicate the mixing effect of complex stacked plate structures but with dramatically reduced space requirements and simpler geometry
2Ease of manufacture
If traditional bulky reactor designs are used, then mixing is achieved, but temperature distribution becomes non-uniform and mixing efficiency decreases
Solution Approach 1:
The invention introduces a rotating gas stream perturbation device with inclined blades that dynamically interact with the gas flow, creating controlled turbulence and swirl that enhances temperature uniformity and mixing efficiency compared to static traditional mixing structures
Solution Approach 2:
The invention optimizes the blade inclination angle as a critical parameter to control the degree of gas stream perturbation, allowing precise adjustment of mixing intensity and temperature distribution homogeneity to achieve optimal reaction conditions
