DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a deodorizing device,
In particular, organic waste (hereinafter, simply referred to as “organic waste”) such as food waste, vegetable waste, and the like discharged from food-related industries, processing plants for agriculture, forestry and fishery products, and general households is fermented to produce organic matter. The present invention relates to a small-sized deodorizing device suitable for use in combination with an organic waste processing device that converts to fertilizer.

[0002]

2. Description of the Related Art Conventionally, most of organic wastes discharged from food-related industries, processing plants for agriculture, forestry and fishery products, general households and the like have been treated by incineration or landfill.

[0003] However, organic waste is liable to decay, is unsanitary, emits a bad smell, causes harmful insects and harmful animals, and is capable of treating organic waste by incineration and landfill. In recent years, as a device that can treat organic waste in a sanitary manner, many organic waste treatment devices that ferment organic waste and convert it to organic fertilizer have been proposed and put into practical use. Is coming.

[0004]

These organic waste treatment apparatuses have many points to be improved. Among them, the organic waste is fermented and converted into organic fertilizer. In this process, the decomposition of organic waste produces malodorous substances such as ammonia, hydrogen sulfide, methyl mercaptan, and trimethylamine in addition to moisture and carbon dioxide. There was a problem that it would cause the next pollution.

In order to cope with this problem, various types of deodorizing devices are usually provided in an organic waste processing apparatus. However, the organic waste processing apparatus must be easily attached to this type of organic waste processing apparatus. A small and inexpensive deodorizing device that has a low deodorizing ability cannot completely eliminate the possibility that malodorous substances that could not be deodorized by the deodorizing device are released into the atmosphere.

[0006] In order to completely deodorize, a large and expensive deodorizing device is required, which places restrictions on the installation location of the device, and in addition to the organic waste treatment device including the deodorizing device. There is a problem that the equipment cost rises significantly,
Therefore, there has been a demand for the development of a small, inexpensive deodorizing apparatus having a high deodorizing ability.

[0007] In order to meet the above demand, the present invention has, in particular,
An object of the present invention is to provide a compact, high-deodorizing, and inexpensive deodorizing apparatus suitable for use in combination with an organic waste processing apparatus.

[0008]

In order to achieve the above object, a deodorizing apparatus according to the present invention introduces an ozone generating chamber and a gas containing ozone and a malodorous substance generated in the ozone generating chamber and arranges the gas inside the chamber. In a deodorizing apparatus comprising a mixing chamber for uniformly mixing with a mixed static mixer and a spray chamber for introducing the mixed gas in the mixing chamber and washing with water sprayed from a spray nozzle, a mixing chamber in which a static mixer is disposed. The gas passage of the chamber is formed in a vertical direction, and a spray nozzle is provided at an upper portion of the mixing chamber.

In this deodorizing apparatus, in a mixing chamber, ozone generated in an ozone generating chamber and a gas containing a malodorous substance are uniformly mixed by a static mixer, and then washed with water sprayed from a spray nozzle in a spray chamber. Thus, the odorous substances contained in the gas are oxidized by ozone and dissolved in water, so that the odorous substances can be reliably removed.

[0010] Further, by forming the gas flow path of the mixing chamber in which the static mixer is disposed inside in a vertical direction, dust contained in the gas does not accumulate in the middle of the flow path, and the ozone and the ozone are mixed. Both can be uniformly mixed without being affected by the specific gravity difference with the gas containing the malodorous substance.
By disposing the spray nozzle in the upper part of the mixing chamber, the odorous substances contained in the gas can be dissolved and removed in water, and the dust adhering to the static mixer can be washed out to keep the static mixer clean.
