Reactor Device for Dehydrating Carrier Medium
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reactor devices face challenges in allowing unhindered release of hydrogen gas during the dehydration of a carrier medium, particularly due to the endothermic nature of the dehydration reaction and the need for sufficient heat input, which is hindered by the small pipe diameter required for effective heat transfer.
Innovation Solution
The reactor device features an antechamber connected to multiple reaction chambers via a first connection opening, allowing for controlled flow of the carrier medium and heat transfer, with a heat transfer space between the reaction tubes and the reactor housing, ensuring uniform loading and improved flow conditions, and includes design elements like a heating unit and separating elements to manage pressure and flow efficiently.

Engineering Contradiction Analysis
1Use of energy by moving object
If a tube bundle reactor is used to provide sufficient heat input for the endothermic dehydration reaction, then heat transfer efficiency is improved, but the pipe diameter must be small which reduces the cross-section and impedes hydrogen gas release
Solution Approach 1:
The reactor is divided into multiple reaction chambers (at least five, preferably at least 10, 20, 50, 100, or 120) that are connected in parallel to a common antechamber. This segmentation allows the system to maintain a large total cross-sectional area for hydrogen release while each individual reaction chamber can have a smaller diameter optimized for heat transfer. The parallel arrangement of multiple chambers provides both the heat transfer surface area needed for the endothermic reaction and the total flow capacity for unhindered hydrogen gas release.
2Productivity
If multiple reaction chambers are connected directly to a common inlet, then scaling of reactor power is enabled, but uniform distribution of carrier medium to all reaction chambers is difficult to achieve
Solution Approach 1:
An antechamber is introduced as an intermediary component between the single inlet and the multiple reaction chambers. The carrier medium enters the antechamber first, where it is distributed to all reaction chambers through multiple connection openings. This intermediary chamber ensures uniform pressure distribution and homogeneous flow conditions to all reaction chambers, enabling scalable reactor power while maintaining precise and uniform carrier medium distribution across all parallel reaction paths.
3Use of energy by moving object
If the reaction chambers are arranged to maximize heat transfer surface area, then heat input is improved, but pressure differences between chambers may affect reaction uniformity
Solution Approach 1:
The antechamber is designed to create equipotential pressure conditions for all reaction chambers. By providing multiple connection openings from the antechamber to each reaction chamber and ensuring the antechamber acts as a common pressure equalization zone, the system minimizes pressure differences between chambers. This equipotential design ensures that all reaction chambers operate under uniform pressure conditions, maintaining reaction uniformity while allowing the chambers to be arranged for maximum heat transfer surface area.

Implementation Method 1
A heat transfer medium in the heat transfer space serves to transfer heat from the heat transfer medium to the carrier medium
Implementation Method 2
