The invention discloses a
fish meal waste gas purifying and decomposing device, which belongs to the field of
fish meal environmental protection equipment. The device comprises a cover plate, strong oxidization nets, a groove body,
ultraviolet lamps, a steel strip and soft magnetic strips, wherein the cover plate is arranged on the upper part of the groove body through a screw hole; the strong oxidization nets are arranged in the groove body at certain intervals; a plurality of
ultraviolet lamps are arranged on both sides of the groove body; the steel strip is U-shaped; the surface of the steel strip is coated with
zinc or
chromium; the edges of the strong oxidization nets are provided with the soft magnetic strips, so that the strong oxidization nets are convenient to detach and clean; the groove body is arranged in a maze form; the strong oxidization nets are made of
metal titanium wire nets, and are used for oxidizing
titanium into
titanium dioxide
nanotube arrays in an
electrolyte containing
fluorine ions at a low-
voltage; and the
voltage of the
low voltage is 20-60V. According to the
fish meal waste gas purifying and decomposing device,
superoxide ion radicals and hydroxyl radicals with extremely strong oxidizing actions generated by
titanium dioxide under the
irradiation of
ultraviolet light can be used for decomposing organic matters with
odor in fish
meal waste gas into nontoxic
carbon dioxide, water and nontoxic inorganic small molecular minerals, so that the device is simple and practical.
