Solution Overview
Problem
Conventional liquid-vapor separators in forced circulation evaporators produce foams and caking, reducing efficiency in evaporation and solid substance removal due to spray nozzle injection, leading to inefficient flashing and crystal formation.
Innovation Solution
A cyclone type liquid-vapor separator with a chamber, inlet part, and partition walls that form vortexes and prevent mist from rising, combined with demisters and vortex breaking members to enhance evaporation efficiency and form round crystals, eliminating the need for spray nozzles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If spray nozzle injection is used in the liquid-vapor separator, then the flashing area is ensured, but foams are produced and mixed with vapors, reducing evaporation efficiency
Solution Approach 1:
The invention removes the spray nozzle injection system from the liquid-vapor separator, extracting the harmful foam-generating mechanism while preserving the flashing area function through alternative means (chamber design and vapor discharge pathways)
Solution Approach 2:
The invention converts the harmful foam production into beneficial vapor-liquid separation by designing the chamber to allow vapors to rise and discharge separately from concentrated liquid, turning the mixing problem into an efficient separation mechanism
2Productivity
If spray nozzle injection is used in the liquid-vapor separator, then the flashing area is ensured, but caking occurs and crystals are produced, reducing solid substance removal efficiency
Solution Approach 1:
The invention extracts the spray nozzle injection mechanism that causes caking and unwanted crystal formation, replacing it with a chamber design that allows controlled vapor-liquid separation without the mechanical disruption that leads to solid substance aggregation
Solution Approach 2:
Instead of injecting liquid upward through spray nozzles (which causes caking), the invention allows vapors to rise naturally from the bottom and discharge from the top, inverting the flow direction to prevent solid substance aggregation while maintaining flashing area
3Productivity
If a reflection plate or diffusion nozzle is disposed in the chamber, then the flashing area is ensured, but the device complexity increases
Solution Approach 1:
The chamber structure serves multiple functions simultaneously: it provides the flashing area, enables vapor-liquid separation, and facilitates vapor discharge, eliminating the need for separate reflection plates or diffusion nozzles and reducing overall device complexity
Solution Approach 2:
The invention merges the functions of the reflection plate, diffusion nozzle, and vapor discharge pathway into a single integrated chamber design, simplifying the separator structure while maintaining effective flashing area and separation performance

Implementation Method 1
an inlet part (120) coupled to a side surface of the chamber (110) in a tangent line direction of an inner peripheral surface of the chamber (110) so as to inject the treatment liquid introduced thereinto, so that the treatment liquid is turned in the form of vortexes along the inner peripheral surface of the chamber (110)
Implementation Method 2
a chamber (110) having an internal space formed therein so that the treatment liquid introduced thereinto is depressurized and evaporated to allow the vapors generated through the evaporation to be discharged through a vapor outlet (111) formed on the top thereof
Implementation Method 3
a chamber (110) having an internal space formed therein so that the treatment liquid introduced thereinto is depressurized and evaporated
Implementation Method 4
at least one or more partition walls (130) disposed in an area between the inlet part (120) and the vapor outlet (111) of the internal space of the chamber (110) in such a manner as to protrude from the inner peripheral wall of the chamber to prevent the mist contained in the vapors produced from moving upwardly
