Reactor Suppression Flow Passage for Heat Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stack type reactors experience heat dissipation or heat inflow through the side surface of the reaction side flow passage, leading to inefficient reactions due to temperature deviations.
Innovation Solution
A reactor design incorporating a suppression flow passage adjacent to the reaction side flow passage, where a suppression fluid prevents heat dissipation or inflow by flowing through this passage, which is not stacked with the heat medium side flow passage, and allows communication with the heat medium side flow passage to facilitate heat management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the reaction side flow passage is exposed to the outside on the side surface, then the device structure is simplified, but heat dissipation or heat inflow occurs leading to temperature deviation and deteriorated reaction efficiency
Solution Approach 1:
The reactor is divided into multiple flow passages including reaction side flow passages, heat medium side flow passages, and suppression flow passages. Each passage serves a specific function, allowing the system to manage heat transfer and reaction conditions independently, thus resolving the contradiction between structural simplicity and reaction efficiency.
Solution Approach 2:
A suppression flow passage is introduced as an intermediary between the reaction side flow passage and the external environment. This suppression passage contains a suppression fluid that prevents direct heat exchange between the reaction fluid and the outside, thereby maintaining reaction temperature while preserving the exposed side surface structure.
2Use of energy by moving object
If the heat medium side flow passage is stacked on all surfaces, then heat exchange efficiency is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The heat medium side flow passages are stacked only on specific surfaces where heat exchange is required, rather than on all surfaces. This local approach maintains heat exchange efficiency while reducing manufacturing complexity and allowing the side surfaces to remain exposed for other functional or structural reasons.
3Productivity
If the suppression flow passage is added to suppress heat dissipation, then reaction efficiency is improved, but the device complexity increases
Solution Approach 1:
The suppression flow passage is merged with the existing stack type reactor structure, sharing the same modular stacking approach. This integration allows the suppression function to be added without creating a completely separate system, thus improving reaction efficiency while minimizing the increase in device complexity.

Function Achieved in This Case
This design effectively suppresses heat dissipation or inflow, maintaining optimal reaction temperatures and improving reaction efficiency by reducing temperature deviations and pressure loss differences across the reactor.
Implementation Method 1
a heat medium side flow passages which are alternately stacked with the reaction side flow passages and through which flows a heat medium that is a fluid performing heat exchange with the reaction fluid flowing through the reaction side flow passage
Implementation Method 2
a suppression flow passage which is disposed adjacent to a surface of the reaction side flow passage, the heat medium side flow passage being not stacked on the surface, and through which flows a suppression fluid that is a fluid suppressing heat dissipation from the reaction fluid flowing through the reaction side flow passage to the outside, or heat transfer from the outside to the reaction fluid
