Solution Overview
Problem
Existing solution component recovery apparatuses are ineffective in separating and recovering components from solutions where components are not easily separable, such as those with components that solidify under specific conditions, limiting the reuse of recovered components.
Innovation Solution
A method and apparatus that reduce pressure and adjust temperature to separate components, preventing solidification of the first component and evaporating the second component below its solidification temperature, allowing for better recovery and reuse of both components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If pressure is reduced to evaporate the second component, then separation efficiency is improved, but the first component may solidify and clog the system
Solution Approach 1:
The patent applies parameter changes by precisely controlling temperature and pressure parameters during the separation process. The temperature is maintained within a specific range below the solidification point of the first component while pressure is reduced to enable evaporation of the second component. This parameter optimization resolves the contradiction by allowing efficient separation without causing solidification.
Solution Approach 2:
The patent utilizes phase transitions by controlling the evaporation of the second component through pressure reduction while preventing phase change (solidification) of the first component. The selective phase transition of only the second component enables separation while avoiding the harmful solidification of the first component that would clog the system.
2Productivity
If temperature is increased to promote evaporation, then recovery efficiency is improved, but the first component solidifies and cannot be reused
Solution Approach 1:
The patent optimizes temperature parameters by maintaining them below the solidification point of the first component while still promoting evaporation of the second component through pressure reduction. This parameter control enables high recovery efficiency while preserving the usability of the first component by preventing solidification.
Solution Approach 2:
The patent replaces thermal-driven evaporation (heating) with pressure-driven evaporation. Instead of increasing temperature to promote evaporation, the system reduces pressure to lower the boiling point of the second component, enabling evaporation at lower temperatures that do not cause solidification of the first component.
3Device complexity
If existing separation methods are used for non-separable components, then equipment simplicity is maintained, but separation and recovery of multiple components is insufficient
Solution Approach 1:
The patent achieves enhanced separation capability with simple equipment by optimizing operational parameters (temperature and pressure). The method uses controlled pressure reduction and temperature maintenance to enable separation of multiple components including those that solidify, without requiring complex additional separation equipment or structures.

AI summary
In a solution recovery apparatus 40, a solution containing an impregnation agent, the solidification reaction of which progresses in the absence of oxygen and at a predetermined solidification temperature or higher, and a solvent in which the impregnation agent is dissolved is stored in a separation section 41. The pressure in the internal space of the separation section 41 is reduced while supplying air (oxygen) to the solution stored in the separation section 41, with a stirring section 42 stirring the solution and with a heat exchange section 43 adjusting the temperature of the solution to a predetermined separation temperature range below the predetermined solidification temperature, to evaporate the solvent contained in the solution. The evaporated solvent is cooled and recovered by a primary water recovery section 51 and a secondary water recovery section 61. By separating the impregnation agent and the solvent at a reduced pressure and in the predetermined separation temperature range while supplying oxygen as described above, solidification of the impregnation agent is prevented.
