Reactor Lining Vacuum Attachment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Reactor linings face damage and loss of protective effect at reduced pressures due to mechanical loads, as existing connection methods are either labor-intensive or expensive, and fail to maintain contact with the wall section effectively.
Innovation Solution
A reactor system with a vacuum generating device and a lining connected via a fluid port that applies negative pressure between the lining and the wall section, using a protective strip to maintain contact and prevent lifting, even at reduced interior pressures, allowing the vacuum to propagate and counteract internal pressure differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the lining is made thin to reduce cost, then material cost is reduced, but the lining becomes vulnerable to mechanical loads at reduced pressure
Solution Approach 1:
The invention applies a counteracting force principle by introducing a vacuum between the lining and wall section. This vacuum creates a pressure difference that presses the lining against the wall section, counterbalancing the mechanical loads that would otherwise damage the thin lining during reduced pressure operations inside the reactor.
2Strength
If soldering is used to connect the lining to the wall section, then connection strength is improved, but manufacturing complexity and labor increase
Solution Approach 1:
The invention extracts the connection function from the traditional soldering/welding process. Instead of creating a permanent mechanical bond between lining and wall section, the system uses a vacuum-generated adhesive force that eliminates the need for complex connection processes while maintaining the protective function.
3Strength
If explosion cladding is used to connect the lining, then connection strength is improved, but material consumption and cost increase
Solution Approach 1:
The vacuum pressure difference creates a holding force that replaces the need for explosion cladding. This allows the use of thinner lining material while maintaining secure attachment, as the vacuum counteracts the forces that would otherwise require thick material or explosive bonding for security.
4Stability of the object's composition
If the lining is pressed against the wall section by overpressure, then connection stability is improved, but the system cannot operate at reduced pressure
Solution Approach 1:
The invention inverts the pressure application logic. Instead of using internal overpressure to secure the lining, the system applies vacuum from the external side (between lining and wall section). This inverted approach allows the lining to be secured during reduced pressure operations while maintaining stability across the full pressure range.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system ensures the lining remains securely attached to the wall section at all pressures, preventing damage and maintaining the protective barrier effectively, even with thin, cost-effective tantalum linings, and reduces the risk of deformation during welding.
Implementation Method 1
at least one fluid connection (6) which is connected to a vacuum generating device (7) and is subjected to negative pressure runs through the wall section (2) which opens out between the inside (3) and the lining (5)

AI summary
Reactor (1) comprises: at least one wall section having an inner surface (3) bounding an interior space (4); a lining (5) arranged on the inner surface of at least one wall (2) to face the interior space; and at least one fluid connection, to which a negative pressure is applied, and which is structured to run through at least one wall section to open into a space between the inner surface and the lining. An independent claim is also included for forming a reactor comprising inserting a lining into an interior space bounded by at least one wall section having an inner surface, such that the lining is arranged on the inner surface of at least one wall to face the interior space, and applying a negative pressure to a space between the inner surface and the lining via at least one fluid connection running through at least one wall section.
