Removable Liner for Stirred Tank Reactor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current chemical and biological reactors require time-consuming disassembly, cleaning, and reassembly after each use, and are limited by the materials used, which can lead to contamination and mechanical constraints, especially when dealing with high pressures and varied reaction conditions.
Innovation Solution
The development of removable reactor liners that are chemically and biologically inert, allowing for quick replacement and facilitating the use of reactors made from non-inert materials, enabling controlled chemical and biological reactions with varied conditions without the need for extensive cleaning and reassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional reactors are used, then the reactor body must be made from chemically inert materials to prevent contamination, but this limits material selection and increases cost. The removable liner allows the reactor body to be made from cheaper, non-inert materials while the liner provides the necessary chemical inertness
Solution Approach 1:
The reactor is divided into two separate components: a reusable reactor body and a replaceable liner. The liner is segmented to fit within the reactor body, allowing independent replacement of the liner without replacing the entire reactor system. This segmentation enables the reactor body to be made from cheaper materials while the liner provides chemical inertness.
Solution Approach 2:
The liner acts as an intermediary barrier between the reaction medium and the reactor body. It mediates the chemical interaction by providing a chemically inert surface that prevents contamination of the reactor body, while allowing the reactor body to be made from materials that would otherwise be unsuitable.
2Reliability
If the entire reactor is disassembled and cleaned after each use, then contamination is prevented, but this is time-consuming and laborious. The removable liner allows quick replacement without extensive cleaning of the reactor body
Solution Approach 1:
The liner is extracted as a separate, removable component from the reactor body. After each use, the liner is removed and replaced with a clean liner, while the reactor body remains in place and does not require disassembly or cleaning. This extraction eliminates the time-consuming cleaning process while maintaining aseptic cleanliness.
Solution Approach 2:
The liner is designed as a disposable or easily replaceable component that is replaced after each use rather than cleaned and reused. This approach prioritizes speed and simplicity over cost savings from reuse, eliminating cleaning time while maintaining reliability through fresh liners.
3Ease of manufacture
If many components are disassembled and reassembled, then the reactor can be cleaned and maintained, but this is laborious and prone to assembly errors. The removable liner simplifies the process by reducing the number of components that need to be handled
Solution Approach 1:
The reactor system is segmented into a permanent reactor body and a removable liner. This segmentation reduces the number of components that need to be disassembled and reassembled, simplifying the cleaning and maintenance process while reducing the risk of assembly errors.
Solution Approach 2:
The liner is pre-assembled and pre-tested before installation in the reactor body. This preliminary action ensures that the liner is ready for immediate use and reduces the complexity of the overall assembly process, as the liner comes pre-prepared rather than requiring assembly during the main process.
