Capacitive Deionization Filter for Scale-Free Water Heater Boilers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water heaters face issues with scale formation due to calcium ions in the water, leading to reduced durability and lifespan, with no effective technology available to prevent this problem.
Innovation Solution
A scale-free boiler system that includes a filter using capacitive deionization (CDI) to remove ionic materials from the water based on electrical force, preventing scale formation. The filter can selectively activate a removal mode to remove ions and a regeneration mode to regenerate the electrode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If water is heated in a water heater, then heating function is provided, but calcium ions precipitate as calcium carbonate causing scale formation that reduces durability and lifespan
Solution Approach 1:
The patent applies preliminary action by removing calcium ions from water before heating occurs. The water treatment device is installed in the water supply line before the water heater, pre-treating the water to prevent scale formation during subsequent heating operations. This proactive approach eliminates the root cause of durability issues before they can manifest in the heating system.
2Temperature
If conventional water heaters are used, then heating is provided, but no technology is available to prevent scale formation
Solution Approach 1:
The patent applies the extraction principle by removing harmful calcium ions from the water supply before they can enter the heating system. The water treatment device extracts and removes calcium ions through ion exchange or filtration mechanisms, separating the harmful substances from the water that will be used for heating. This prevents scale formation without interfering with the heating function.
3Reliability
If a filter is added to remove ionic materials, then scale formation is prevented, but device complexity increases
Solution Approach 1:
The patent applies the intermediary principle by introducing a water treatment device as a mediator between the water supply and the water heater. This intermediary component handles the complex task of ion removal, allowing the main heating system to remain simple and unchanged. The filter serves as a bridge that protects the heating system from scale without requiring modifications to the heater itself.
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
The system effectively prevents scale formation in water heaters, thereby increasing their durability and lifespan, and allows for semi-permanent use of the filter without physical replacement.
Implementation Method 1
the filter may remove the ionic material in a capacitive deionization scheme in the removal mode
Implementation Method 2
a filter for removing, based on an electrical force, an ionic material contained in the water flowing along the main flow path
