Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] As shown in the figure, the fishmeal waste gas purification and degradation device includes a cover plate 1, a strong oxidation net 2, a tank body 3, an ultraviolet lamp 4, a steel strip 5, and a soft magnetic strip 6. The cover plate 1 is installed on the tank body 3 through screw holes. In the upper part, strong oxidation nets 2 are installed at intervals (1-2 meters) in the tank body 3, and multiple ultraviolet lamps 4 are installed on both sides of the tank body 3. Generally, four ultraviolet lamps are installed next to each strong oxidation net 2. light lamp4.

[0017] The steel bar 5 is U-shaped, and the surface is plated with zinc or chromium, which is convenient for the adsorption of the soft magnetic strip 6; the edge of the strong oxidation net 2 is provided with a soft magnetic strip 6, which is convenient for the overall disassembly a...

Abstract

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.

Description

technical field [0001] The invention relates to a purification and degradation device, mainly a fish meal waste gas purification and degradation device, and belongs to the field of fish meal environmental protection equipment. Background technique [0002] my country is rich in fishery resources, and the fishmeal processing industry is relatively developed. The production of fishmeal is completed by cooking, pressing, drying and other processes of low-value fish. The processing process produces a large amount of toxic waste gas with a foul smell. The main components of the waste gas are trimethylammonium, dimethyl disulfide, dimethyl trisulfide, styrene , butyric acid, etc. If they are directly discharged, they will cause serious pollution to the atmosphere. Therefore, as domestic requirements for environmental protection are getting higher and higher, some fishmeal processing plants that do not have waste gas treatment have been relocated or shut down one after another. ...
