Solution Overview
Problem
Conventional air cleaning systems are inefficient in removing ultrafine dust and nanometer-scale dust, and existing methods using water injection are costly, noisy, and difficult to miniaturize.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If water is compressed and injected in a spray manner using a motor pump, then fine dust can be removed, but manufacturing costs become high and noise cannot be eliminated
Solution Approach 1:
The patent replaces the motor pump-based compression system with a centrifugal generation system. Water is fed into a centrifugal generator that rotates at high speed, utilizing centrifugal force to atomize and spray water particles without requiring a motor pump, thereby eliminating the associated noise and reducing manufacturing costs
Solution Approach 2:
The centrifugal generator utilizes high-speed rotation to create centrifugal force that atomizes water into fine particles. The rotational motion effectively vibrates and breaks up water streams into micro-sized droplets, achieving fine dust removal without conventional pumping mechanisms
2Object-affected harmful factors
If a motor pump is used to lift and spray water, then water can be injected for dust removal, but the apparatus becomes large and noisy
Solution Approach 1:
The motor pump is completely replaced by a centrifugal generation system that uses rotational kinetic energy to both lift and spray water simultaneously. This integration eliminates the need for separate pumping components, reducing overall apparatus volume
Solution Approach 2:
The centrifugal generator combines multiple functions into a single component: it lifts water from the reservoir, atomizes it into fine particles, and directs the spray outward. This merging of lifting, atomization, and spraying functions into one rotating component significantly reduces the apparatus footprint
3Object-affected harmful factors
If conventional filtration methods are used, then visible dust can be collected, but ultrafine dust and nanometer-scale dust cannot be filtered effectively
Solution Approach 1:
The patent changes the state of water from liquid streams to micro-sized droplets through centrifugal atomization. This parameter change in water particle size enables effective capture of ultrafine and nanometer-scale dust particles that conventional filters cannot remove
Solution Approach 2:
The centrifugal generator creates a distributed array of micro-sized water droplets that act as numerous small filtering elements. This droplet-based filtration approach provides high surface area and porosity equivalent, enabling capture of ultrafine particles throughout the air flow path

Function Achieved in This Case
Achieves high-efficiency filtration of ultrafine and fine dust with reduced noise and manufacturing costs, while also providing improved humidification performance using clean moisture.
Implementation Method 1
a centrifugal generator (300) that rotates, thereby generating a centrifugal force; water fed into the centrifugal generator is lifted upward in a centrifugal manner and is scattered to form a moist layer
Implementation Method 2
a rotational column 30 that is coupled at a predetermined portion in the center of the lower body 6 to be rotatably mounted, lifts water stored in the reservoir tank 18 upward in a centrifugal manner and then scatters the same to form a moist layer 20
Implementation Method 3
external air inflowing through air input holes formed below a moist layer is adhered to water molecules in the moist layer and drops down, thereby enabling fine particulate matter

AI summary
An air cleaning apparatus with a moist filter is disclosed. More particularly, the present invention relates to an air cleaning apparatus with a moist filter, being operated such that: water stored in a bottom reservoir tank flows upward in a centrifugal manner; water molecules are finely cleaved in a microfine state and injected through multiple injection holes in the same centrifugal manner to become moist; under such conditions, water flowing into a rotational column, to which a centrifugal force is applied, is filtered while circulating a cycle wherein external air inflowing through air input holes formed below a moist layer is adhered to water molecules in the moist layer and drops down, thereby enabling ultrafine dust as well as fine dust to be filtered with high efficiency and excellent economic advantage.
