摘要： An active plasma sterilizer (APS) system for sterilization/decontamination is provided, including a sterilization box and a plurality of compact portable plasma reactors (CPPRs) disposed in the sterilization box and configured for generating surface dielectric barrier discharge (SDBD) for generating and distributing reactive oxygen and nitrogen species (RONS) such as ozone. Each of the plurality of CPPRs includes a reactor panel and a power supply circuit. The reactor panel includes one or more electrodes separated by a dielectric medium. The active plasma sterilizer (APS) system may include an ozone decomposition module having a heating element connected to a power supply and configured to decompose ozone by heating ozonated air; a power supply module for supplying power to the heating element; connecting pipes for providing paths for ozonated air to travel through; and an air pump configured to circulate the ozonated air generated.

摘要： Embodiments of the subject invention relate to a small modular self-contained surface plasma device for decontamination of air and surfaces within enclosed volumes. Embodiments of the subject invention relate to a method and apparatus using the technical process of dielectric barrier discharge (DBD) surface plasma generation from ambient atmosphere for decontamination of air and surfaces within enclosed volumes. The primary application mode is for preservation of perishable commodities within industrial shipping containers through reduction of surface spoilage organisms and destruction of evolved gaseous ethylene that causes premature ripening. Additional implementations include deployment for oxidation of surfaces and/or container atmospheres in applications to diminish or eradicate pesticides, toxins, chemical residues, and other natural or introduced contaminants. Other embodiments envisioned include incorporation of device capabilities and or ancillary modules for feedback input (e.g. ozone sensor(s) to maintain steady state levels, self-tuning circuitry to adjust operating frequency), communication (e.g. among modules, RFID data loggers, Wi-Fi output), and programing (e.g. user input of container volume, transit time, ozone level, etc.).
