Heat Storage Reaction System Sliding Jig Module Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional heat storage combustion facilities face efficiency issues when replacing material modules, as the process requires stopping operations and allowing workers to enter the facility, leading to prolonged downtime and reduced efficiency.
Innovation Solution
The proposed heat storage reaction system allows for individual control of connection passages between a chamber and multiple beds, enabling material module replacement without stopping the system's operation. This is achieved through a sliding jig that allows for external replacement of material modules, eliminating the need for workers to enter the facility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If material modules are replaced in conventional heat storage combustion facilities, then the material modules can be renewed, but the system must stop operations and workers must enter the facility, causing prolonged downtime
Solution Approach 1:
The facility is divided into independent beds (first bed, second bed, third bed) that can be operated separately. Each bed has its own material modules that can be replaced independently without affecting other beds, allowing continuous operation while one bed undergoes maintenance
Solution Approach 2:
A sliding jig is introduced as an intermediary tool to replace material modules externally without requiring workers to enter the facility. The sliding jig slides into the bed through an opening, pushes the material modules out, and can be operated from the outside, eliminating the need for facility shutdown and worker entry
2Reliability
If the system stops operations to replace material modules, then replacement can be performed safely, but facility efficiency is reduced due to prolonged downtime
Solution Approach 1:
The system maintains continuous operation by having multiple beds that can function while one bed is being serviced. The hot gas circulation path can continue through other beds, and material module replacement in one bed does not interrupt the overall system operation, eliminating downtime
Solution Approach 2:
The sliding jig acts as an intermediary that enables safe external replacement of material modules without requiring system shutdown. It provides a mechanism to manipulate material modules from the outside through controlled pushing motion, ensuring safety while maintaining operational continuity
3Ease of operation
If workers enter the facility to replace material modules, then direct access is possible, but operational efficiency is reduced and safety risks increase
Solution Approach 1:
The sliding jig serves as an intermediary tool that provides direct access to material modules from the outside without requiring worker entry. It slides into the bed through an opening, engages with material modules, and pushes them out externally, maintaining ease of operation while eliminating the need for worker entry and associated efficiency losses
4Device complexity
If material modules are disposed in fixed order, then system operation is simplified, but replacement flexibility is limited
Solution Approach 1:
Material modules are segmented into individual replaceable units within each bed. Each module can be independently manipulated by the sliding jig, allowing flexible replacement of specific modules without requiring sequential removal of all modules, thus providing both simplicity and flexibility

AI summary
A heat storage reaction system according to an embodiment includes: a chamber that includes a combustion chamber; a plurality of beds that are disposed in a lower portion of the chamber, in which a plurality of trays having a material module disposed therein are fixed to form layers; a connection passage that connects the lower portion of the chamber and upper portions of each bed; and a valve that controls opening and closing of the connection passage, in which each of the beds may include one or more opening and closing parts with one side surface opened.
