Steam Generator Deflector Hood for Complete Evaporation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for generating steam are either time-consuming and energy-intensive or result in incomplete evaporation, leaving a significant portion of the liquid unevaporated.
Innovation Solution
A steam generator design featuring a deflection hood and a pressure vessel with a heating element, where the liquid is heated to a temperature above its boiling point within the vessel, and the overheated liquid is directed to the outside where it meets a deflection hood, ensuring minimal liquid remains unevaporated, with continuous flow and controlled heating to maximize evaporation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If flash evaporation is used to generate steam quickly, then steam generation speed is improved, but evaporation completeness deteriorates (significant portion of liquid remains unevaporated)
Solution Approach 1:
The invention divides the evaporation process into two distinct stages: (1) rapid heating and partial evaporation in a pressurized chamber, and (2) secondary evaporation on the outer surface of the pressure vessel. This segmentation allows each stage to optimize for its specific function, achieving both speed and completeness
Solution Approach 2:
The invention extends the evaporation process from a single internal space to a two-dimensional surface (the outer surface of the pressure vessel). By directing unevaporated liquid onto the heated outer surface, it creates an additional evaporation zone that captures and evaporates the remaining liquid
2Quantity of substance
If large quantity of water is heated simultaneously to generate steam, then steam output is improved, but energy consumption and time required deteriorate
Solution Approach 1:
The pressure vessel's outer surface is heated passively by the superheated liquid inside through thermal conduction, eliminating the need for external heating elements. The system uses its own internal energy to perform secondary evaporation, significantly reducing additional energy consumption
Solution Approach 2:
The invention recovers the thermal energy that would otherwise be wasted in the superheated liquid by using it to evaporate the unevaporated portion on the outer surface, maximizing energy utilization efficiency
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
This approach allows for rapid, cost-effective, and energy-efficient steam generation with minimal residual liquid, optimizing evaporation by maintaining the liquid below its boiling point within the vessel and utilizing the deflection hood to ensure complete evaporation outside.
Implementation Method 1
the liquid in the pressure vessel is heated by means of the heating element
Implementation Method 2
a first part of the liquid evaporating and a second part of the liquid remaining liquid
Implementation Method 3
The superheated liquid then escapes from the pressure vessel, for example, through a nozzle or outlet, and evaporates instantly due to the sudden change in surrounding pressure and the resulting expansion
Implementation Method 4
the second part of the liquid, in particular, hits the baffle and is directed to the outside of the pressure vessel... which has a temperature higher than the evaporation temperature or the boiling temperature of the liquid that is directed to the outside
Implementation Method 5
the liquid in the pressure vessel transfers some of its heat to the pressure vessel, so that the outside of the pressure vessel is also heated
