Solution Overview
Problem
Current cleaning techniques using steam and water mist lack the specific effects of nano-order mist collisions for efficient cleaning, sterilization, and surface processing, particularly in reducing liquid usage and achieving dry, drug-free, and water-saving outcomes.
Innovation Solution
A high-speed nano mist with droplets of 1 nm to 10000 nm in diameter traveling at 50 m/s to 1000 m/s is produced by ejecting water vapor and pressurized gas from a sealed container through a jet nozzle, enabling sterilization, cleaning, and surface processing without wetting the target, utilizing phenomena like OH radical generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If steam and water are mixed at constant pressure and sprayed from a nozzle, then cleaning capability is improved, but liquid usage is excessive and wetting occurs
Solution Approach 1:
The invention changes the particle diameter parameter from micron-order to nano-order (1-10000 nm), and increases the ejection speed to 50-1000 m/s. These parameter changes enable the mist to evaporate instantly upon contact with the target surface, achieving cleaning without wetting and dramatically reducing liquid usage from hundreds of mL/min to minimal amounts.
Solution Approach 2:
The invention utilizes phase transition by generating steam from water and mixing it with pressurized gas to create a high-speed nano mist. The steam phase allows the liquid to be delivered in a gaseous carrier, which then transitions back to liquid droplets upon ejection, enabling instant evaporation and dry cleaning at the target surface.
2Reliability
If conventional water spraying is used for sterilization and cleaning, then the target surface is wetted and requires drying, but the invention achieves dry processing
Solution Approach 1:
By changing the particle diameter to nano-order (1-10000 nm) and increasing ejection speed to 50-1000 m/s, the mist droplets have sufficient kinetic energy to penetrate biofilms and sterilize surfaces while evaporating before wetting. This parameter change enables sterilization in a dry state, eliminating the need for subsequent drying processes.
3Productivity
If micron-order mist is used for cleaning, then liquid droplets are delivered, but nano-order mist provides specific collision effects for efficient processing
Solution Approach 1:
The invention reduces the particle diameter from micron-order to nano-order (1-10000 nm), which fundamentally changes the collision dynamics. The nano-sized droplets at high speed (50-1000 m/s) penetrate biofilms more effectively and provide enhanced cleaning efficiency compared to larger micron-order droplets, while using minimal liquid quantity.
4Ease of operation
If high-speed nano mist is ejected from a jet nozzle, then dry and drug-free processing is achieved, but specialized equipment is required
Solution Approach 1:
The invention uses pneumatic principles by supplying pressurized gas (0.05-5.0 MPa) to a sealed container with water, generating steam and ejecting it through a jet nozzle at high speed. This pneumatic system enables dry, drug-free processing while maintaining operational simplicity despite the specialized equipment required for generating the high-speed nano mist.
