Air Purifier Ionized Water Layer Dust Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air purifiers using wet dust-removal technology face inefficiencies in removing PM2.5 particles due to reduced water contact area and fail to effectively capture hydrophobic dust, leading to incomplete cleaning.
Innovation Solution
An air purifier design featuring a box body with a filter screen, an air suction device, and a water mist generator that forms an ionized water layer, allowing hydrophilic and hydrophobic dust to be absorbed, combined with a recovery and water circulation system to recycle water and separate dust from the ionized water layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If water mist is used for dust removal, then fine particles can be removed, but the contact area between water and particles is reduced due to bubble protection, reducing removal efficiency
Solution Approach 1:
The patent changes the physical state of water from liquid droplets to ice crystals through freezing. This phase change eliminates the bubble protection effect that limits water-particle contact in liquid form, allowing ice crystals to directly contact and capture dust particles more effectively while maintaining the wet dust-removal mechanism
Solution Approach 2:
The patent utilizes the phase transition of water from liquid to solid state. By freezing water mist into ice crystals, the system overcomes the limitation of reduced contact area caused by bubble formation in liquid water, enabling more effective particle capture through direct solid-particle interaction
2Productivity
If simple water filtration is used, then hydrophilic dust can be removed, but hydrophobic dust penetrates through and cannot be cleaned efficiently
Solution Approach 1:
The patent changes water's surface properties by freezing it into ice crystals. This phase change alters the interaction mechanism between water and dust particles, enabling the system to capture both hydrophilic and hydrophobic dust that would otherwise resist simple water filtration
Solution Approach 2:
The patent converts the limitation of water-based filtration (inability to capture hydrophobic dust) into an opportunity by using frozen water. The ice crystal structure provides a different capture mechanism that works effectively on both hydrophilic and hydrophobic particles, turning a selective limitation into universal effectiveness
