Vapor Compression Distillation Assembly Low-Pressure Flash Boiling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional vapor compression distillation systems are inefficient due to high operating temperatures, long startup times, and the need for expensive materials, as they require heating influent liquid to the boiling point, which wastes energy and necessitates costly insulation and high-temperature-resistant materials.
Innovation Solution
The system operates at a low pressure, allowing influent liquid to flash boil at ambient temperature, eliminating the need for heat exchangers and reducing startup time, by using an external compressor to create a negative pressure environment within the housing, enabling evaporation and condensation at or near room temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If influent liquid is heated to the boiling point for evaporation, then evaporation efficiency is improved, but energy consumption increases and startup time increases
Solution Approach 1:
The patent changes the operating pressure parameter from atmospheric pressure to reduced pressure, which allows water to evaporate at lower temperatures. This parameter change enables evaporation to occur at ambient or near-ambient temperatures, dramatically reducing energy consumption while maintaining evaporation efficiency through the phase change process.
Solution Approach 2:
The patent utilizes phase transitions (liquid to vapor during evaporation, vapor to liquid during condensation) as the core mechanism for water recovery. By operating at reduced pressure, the phase transition occurs at lower temperatures, eliminating the need for high-energy heating while still achieving effective evaporation and condensation cycles.
2Productivity
If influent liquid is heated to the boiling point, then evaporation is achieved, but the system requires expensive high-temperature-resistant materials and insulation
Solution Approach 1:
By changing the pressure parameter to reduced pressure, the operating temperature is lowered to ambient or near-ambient levels. This eliminates the need for expensive high-temperature-resistant materials and thermal insulation, allowing the use of standard, cost-effective materials throughout the system.
3Productivity
If the system operates at high temperature, then evaporation efficiency is improved, but heat loss increases and insulation is required
Solution Approach 1:
The patent changes the temperature parameter from high temperature to ambient or near-ambient temperature by operating at reduced pressure. This eliminates heat loss issues entirely, as no thermal insulation is needed when the system operates at or near room temperature, while evaporation efficiency is maintained through the pressure-dependent phase change mechanism.
