Pneumatic Spray Recirculation for Higher Reaction Yield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spray techniques for generating reaction products face limitations in reaction completion and low product yield due to the limited travel distance of droplets within the spray.
Innovation Solution
A system with a recirculation function is used to collect and re-spray the material, allowing unreacted molecules to react further and incomplete reactions to reach completion, thereby increasing the reaction yield. The system includes a pneumatic sprayer, a collector, and a recirculation loop that allows the unreacted molecules and reaction products to be recycled through the sprayer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If spray techniques are used to generate reaction products, then reaction rate is accelerated, but reaction completion is limited and product yield is low
Solution Approach 1:
The system implements continuous recirculation of the liquid spray discharge through the reaction zone. Unreacted molecules are continuously recycled back through the pneumatic sprayer, allowing multiple reaction opportunities and driving the reaction to completion, thereby resolving the contradiction between fast reaction rate and low product yield
Solution Approach 2:
The system recovers unreacted molecules from the liquid spray discharge and returns them to the reaction process. By collecting and recirculating the spray material, the system prevents loss of unreacted reagents and maximizes conversion to product, thereby increasing overall product yield while maintaining high reaction rates
2Speed
If droplets travel limited distance within the spray, then reaction acceleration occurs, but reaction completion is prevented
Solution Approach 1:
The recirculation system extends the effective duration of droplet reaction by continuously cycling unreacted molecules back through the reaction zone. This maintains the benefits of rapid reaction acceleration while providing multiple opportunities for completion over an extended effective time period
Solution Approach 2:
The system employs periodic recirculation cycles where liquid spray discharge is continuously pumped back through the pneumatic sprayer. This periodic action allows droplets to undergo multiple reaction cycles, effectively extending their residence time and enabling complete conversion while preserving the acceleration benefits of each individual spray cycle
