APPARATUS FOR DECOMPOSING ORGANIC GAS BY DARK PLASMA, AND APPARATUS FOR KEEPING FRESHNESS OF FARM PRODUCT BY USING THE APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a compact apparatus drived by a low voltage, decomposing harmful organic gas used for keeping of freshness such as ethylene gas, and capable of simultaneously killing putrefactive bacteria floating in a container without generating ozone.

SOLUTION: A central energized electrode 2 is stood at the center position on the surface 1a of an electrode-arranging plate 1. Many floating electrodes 3 not connected to current-carrying bodies are stood at a nearly prescribed interval on the positions at a prescribed distance from the central electrode 2 so as to surround the electrode 2. Many outer periphery energized electrodes 4 connected to the current- carrying bodies are stood at an interval at the outer periphery of the floating electrodes 3 so as to surround the group of the floating electrodes 3. The central energized electrode 2 and the outer periphery energized electrodes 4 are connected to a power source 5 for impressing a voltage having an intensity for generating only the dark plasma under atmosphere in the organic gas-decomposing apparatus. The organic gas-decomposing apparatus also has a blowing means 6 for blowing the organic gas to the space among each electrode 2, 3, 4 on the surface 1a of the electrode- arranging plate 1.
