This invention discloses a vaccine separator and its working method that utilizes vapor phase to achieve self-sterilization and cleaning functions. It relates to the field of vaccine separator technology and employs steam cleaning during the cleaning process of the vaccine separator. The principle behind this method is that vapor media have better permeability and diffusion than liquid media, and also possess superior heat dissipation and evaporation effects, resulting in better inactivation of residual bacteria during the separation process. Based on these aspects, a dual-path vapor-liquid structure is proposed, which, in essence, performs targeted and localized cleaning actions based on the injection method of the bacterial mixture during the separation process. This requires real-time interaction between the temperature and pressure environments inside the vessel according to the high-temperature steam injection process, ultimately aiming to improve the overall cleaning effect.

The reaction chamber adopts a three-layer coaxial nested configuration of 316L stainless steel. The inner tube wall has a regular polygonal prism structure, while the outer tube wall has a multi-segment continuously circulating "gradually expanding-constant diameter-gradually contracting" irregular tube structure. High- and low-frequency multi-array ultrasonic transducers are correspondingly arranged on the inner and outer wall surfaces to synergistically construct a blind-zone-free gradient amplification standing wave field. This invention achieves efficient and continuous inactivation of pathogenic microorganisms in mariculture water by targeting and enriching pathogenic microorganisms at the acoustic pressure nodes of the standing wave field, concentrating the excitation of multi-frequency resonant cavitation effects at the acoustic pressure antinodes, and coupling ozone micro-nano bubbles to reduce the cavitation threshold and leverage their high oxidizing properties.
