Autoclave Atmosphere Recirculation for Volatile Component Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Volatile components, such as plasticizers, escape during the treatment of parts in autoclaves, accumulating in the atmosphere and posing risks like autoclave fires, as existing methods do not effectively manage these gases in a closed system.
Innovation Solution
A method involving a circulation system to cool and condense volatile components outside the autoclave, separating them from the atmosphere, and reintroducing the cleaned air back into the autoclave, using a double-pipe cooling section with an inclined design for automatic condensate removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If parts are treated in autoclave at elevated temperature and pressure, then treatment effectiveness is improved, but volatile components escape and accumulate causing fire hazards
Solution Approach 1:
The harmful volatile components are extracted from the autoclave atmosphere through a circulation system that continuously removes gases containing plasticizers and other volatile substances, separating them from the treated parts and preventing accumulation that could lead to fire hazards
Solution Approach 2:
A cooling section acts as an intermediary between the autoclave and the external environment, condensing volatile components from the circulated atmosphere and enabling their removal without directly exposing the autoclave to external cooling mechanisms
2Object-affected harmful factors
If cooling air is continuously introduced to absorb gases, then volatile components are removed, but the system becomes open and loses process control
Solution Approach 1:
The autoclave maintains a controlled atmosphere environment where volatile components are managed through circulation and condensation rather than continuous air introduction, preserving process control while removing harmful substances
Solution Approach 2:
Volatile components are removed by condensing them from gaseous to liquid phase in the cooling section, enabling separation and removal without requiring continuous introduction of cooling air into the autoclave
3Object-affected harmful factors
If volatile components are condensed outside autoclave, then fire hazard is reduced, but system complexity increases
Solution Approach 1:
The circulation system serves multiple functions simultaneously: it removes volatile components from the autoclave atmosphere, condenses them in the cooling section, and maintains pressure equilibrium, reducing the need for separate specialized systems
Solution Approach 2:
The cooling section is integrated with the circulation system, combining the functions of gas circulation, cooling, condensation, and atmosphere management into a unified system that reduces overall complexity
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
Effectively removes undesirable volatile components, preventing autoclave fires by maintaining a safe atmosphere within the autoclave through continuous condensation and removal, specifically applicable in the production of safety glass.
Implementation Method 1
They reach a cooling section, in which they condense out and change into a liquid, in particular viscous, and/or solid state
Implementation Method 2
This ensures that the substances that have condensed out, which are in particular in a liquid or viscous state, are automatically drained from the system by the effect of gravity
Implementation Method 3
the gaseous atmosphere is passed through the inner tube, while a cooling medium, for example water, is located inside the outer tube

AI summary
A method for subjecting parts to elevated temperature and/or pressure in an autoclave, as well as an autoclave itself, are described. In this method, volatile components escaping into the atmosphere inside the autoclave are removed from the autoclave atmosphere by condensing them outside the autoclave. The associated autoclave includes a condensate separator designed as an atmosphere recirculation system, comprising a recirculation device located within the autoclave and a pipe system outside the autoclave.
