Sealed Reactor Cleaning via Injected Cleaning Medium Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reaction systems face challenges in safely cleaning reactors while maintaining a sealed environment to prevent the ingress or egress of outdoor air, particularly when producing reactive products like electrolytes for all-solid-state lithium-ion batteries, which generate toxic gases, necessitating protective measures that hinder efficient maintenance and measurement.
Innovation Solution
A reaction system with a blocking mechanism to isolate indoor air from outdoor air, incorporating a reactor, conveyance apparatus, fluid supply and discharge tubes, and a cleaning medium supply apparatus, allowing for cleaning operations within a sealed environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealed environment is maintained to prevent toxic gas leakage during cleaning operations, then safety is improved, but access for cleaning and maintenance becomes difficult
Solution Approach 1:
The reaction system is divided into a sealed reaction chamber and a cleaning chamber separated by a partition wall with a movable partition. This segmentation allows the cleaning operation to be performed in a separate space while maintaining the seal of the reaction chamber, resolving the contradiction between safety and accessibility.
Solution Approach 2:
A movable partition acts as an intermediary between the sealed reaction chamber and the cleaning chamber. It allows controlled transition between sealed and open states, enabling safe cleaning operations without compromising the integrity of the sealed environment when needed.
2Object-generated harmful factors
If the reaction system is blocked from outdoor air to prevent toxic gas generation, then harmful gas generation is reduced, but cleaning operations require extensive protective measures
Solution Approach 1:
The cleaning function is extracted from the reaction chamber and performed in a separate cleaning chamber. This allows the reaction system to remain sealed and block outdoor air during cleaning operations, preventing toxic gas generation while simplifying the overall protective measure requirements.
Solution Approach 2:
The movable partition is positioned to seal the reaction chamber before cleaning operations begin. This preliminary action ensures the system is already blocked from outdoor air, preventing toxic gas generation during the subsequent cleaning process without requiring additional protective measures.
3Productivity
If continuous production is maintained without opening the system, then productivity is improved, but cleaning and maintenance of components become difficult
Solution Approach 1:
The system is segmented into production mode and cleaning mode through the movable partition and separate cleaning chamber. This allows continuous production in the reaction chamber while enabling easy cleaning and maintenance of components in the isolated cleaning chamber without affecting productivity.
Solution Approach 2:
The movable partition provides dynamic flexibility, allowing the system to switch between sealed production mode and open cleaning mode. This dynamic capability enables continuous production to be maintained when not cleaning, while facilitating easy maintenance when needed, resolving the contradiction between productivity and ease of repair.

AI summary
In a reaction system (1), a reactor (210) is provided in a sealed space covered by a blocking mechanism (111) and includes a supply port of a substance to be treated and a delivery port of a product. A conveyance apparatus (221) conveys the substance to be treated along an extending direction of a cylindrical body inside the cylindrical body. A fluid supply tube (204) is connected to a fluid inlet provided in the reactor and supplies a fluid for production. A fluid discharge tube (206) discharges a fluid inside the reactor from a fluid outlet provided in the reactor. A cleaning medium supply apparatus (232) branches and is connected to at least any one of the supply port or the fluid supply tube and can inject a cleaning medium in the reactor in a cleaning step.
