AI Technical Summary

Technical Problem

Traditional single-channel nozzles suffer from uneven droplet size distribution, low atomization efficiency, short spray distance, and low disinfectant utilization during disinfection. In particular, for active oxides such as hydroxyl radicals, the lifespan is short and the diffusion distance is limited, making it difficult to achieve efficient atomization and stable transport.

Method used

A dual-channel swirling cone nozzle is designed, employing inner and outer solution channels. Through the synergistic effect of the first and second channels, the separation and transport of liquids with different functions and instant mixing at the nozzle are achieved, enhancing the mixing uniformity and atomization effect. Gas-liquid two-phase atomization technology is used to improve the spraying capacity and spatial diffusion.

Benefits of technology

It achieves uniform distribution and efficient transport of droplets, improves disinfection efficiency, and enhances the spatial coverage of active disinfectants. In particular, the mixture of hydroxyl radicals and hydrogen peroxide solution can achieve efficient elimination of a variety of pathogenic microorganisms within 10 seconds.
