Description

  The present invention relates to a method and an apparatus for deodorizing air containing an odorous component. Specifically, the present invention relates to a method and an apparatus for deodorizing air containing an odor component by bringing the air into liquid-liquid contact with an aqueous liquid composition containing a deodorant component.

  In recent years, with increasing awareness of deodorization and deodorization in a living environment, a deodorization method and a deodorization device capable of easily, quickly and effectively removing or reducing air containing odor components such as malodor have been desired.

  The odor components that constitute air, including odor components generated in daily life, include various components derived from human body sweating, excretion, cooking, pets, garbage, etc., and are soluble in water (water-soluble components). Not only odor components) but also many components that are hardly soluble or insoluble in water (hydrophobic components).

  Examples of the water-soluble odor component include ammonia (702 ml / ml; solubility in water; the same applies hereinafter), nitrogen-containing components such as trimethylamine (20 g / 100 ml), acetic acid (100 g / 100 ml), isovaleric acid, and butyric acid. Fatty acid-based components, lower aldehyde-based components such as acetaldehyde and formaldehyde, and the like, and examples of hydrophobic odor components include sulfur-containing components such as hydrogen sulfide (0.33 g / 100 ml) and methyl mercaptan (2.3 g / 100 ml). , Middle and higher aldehyde components such as hexanal, octanal, nonanal, and nonenal.

  Conventionally, as a deodorant for indoor use, a standing type (stationary type) is widely used. However, with this type of deodorant, the air containing the odor component exerts the deodorizing effect by contact with the deodorant by natural convection, so it takes some time to develop the deodorizing effect. I will. Therefore, when it is desired to deodorize in a short time, it is necessary to employ a method of ventilating the odor components in the air or spraying a spray type deodorant.

  The following deodorizing methods have been reported other than the above-mentioned stationary type (stationary type) deodorant, but they are not always satisfactory.

  Patent Literature 1 discloses a method of deodorizing by passing air containing an odor component through a portion from which a water-soluble odor component is removed and a portion from which a hydrophobic odor component is removed. In this device, the deodorizing effect is improved by positively venting the odor component to the odor removing portion, but the device becomes complicated and large because it is necessary to provide two odor removing portions. In addition, only a solution of glutaraldehyde and citric acid is described as a water-soluble odor component removing material, and a solid deodorant material such as activated carbon is exclusively used as a hydrophobic odor component removing material. Stay there.

  Patent Literature 2 describes that VOC such as formaldehyde is blown into water to purify air. However, the structure becomes complicated because it is necessary to provide the first air cleaner and the second air cleaner. Also, there is no teaching about adding a deodorant to water.

  Patent Literature 3 describes a method of purifying air by bringing air into contact with ozone water. However, since an ozone generator is required, it cannot be a simple device. Also, there is no teaching about adding a deodorant to water.

  Thus, there is room for further improvement to easily, quickly and effectively remove or reduce the odor component from air containing both the water-soluble odor component and the hydrophobic odor component.

<Deodorization test method>
The deodorization test is based on [II] -2 Deodorization Efficacy of the Efficacy Test Method (revised in 2005) published on the website of the Association of Aroma Deodorants and Deodorants (http://www.houkou.gr.jp/) The test was performed according to the test method (chemical deodorization). Specifically, it is as follows.
(1) The test method used the detection tube method.
(2) The test samples used were the samples shown in Table 1 above.
(3) The application method was a static method, and the test container used was a 5 L capacity air bag with a cock.
(4) The test procedure is as follows. An air bag containing a test sample and air containing an odor component and an air bag (blank) containing only air containing an odor component were prepared, and both were filled with odorless air to adjust the initial concentration of the odor component to 100 ppm. The odor component concentration was measured over time at room temperature (about 20 ° C.). See FIG.
(5) The determination method is as follows. The concentrations of the odor components of the test sample and the blank were measured over time, and the deodorization rate (%) was calculated by applying the following formula.

Deodorization rate = (1 − {[A _t −B _t ] / A _t }) × 100
A _t: concentration after the blank time t B _t: the results of time concentration deodorization test after t sample shown in Figures 3-6.

Deodorization rate was shown. The aeration (acid deodorant) showed a higher deodorization rate in a shorter time than the aeration (deodorant).

  As shown in FIG. 4, when the odor component is water-soluble acetic acid, the aeration (deodorant liquid) shows a high deodorization rate in a very short time as compared with the stationary type, and is higher in a short time than the aeration (water). Deodorization rate was shown.

  From FIG. 5, when the odor component is hydrophobic methyl mercaptan, the aeration (deodorant liquid) showed a higher deodorization rate in a shorter time than the aeration (water). Although the deodorizing speed is slightly slower than the case of the water-soluble odor component (FIGS. 3 and 4), it is a good result.

  As shown in FIG. 6, when the odor component is hydrophobic hydrogen sulfide, the aeration (deodorant liquid) shows a higher deodorization rate in a shorter time than the stationary type, and is higher in a shorter time than the aeration (water). Deodorization rate was shown. Although the deodorizing speed is slightly slower than the case of the water-soluble odor component (FIGS. 3 and 4), it is a good result.

  ADVANTAGE OF THE INVENTION The deodorizing method of this invention can remove or reduce an odor component easily, quickly and effectively by making the air containing an odor component contact positively (aeration) with a deodorant liquid. Therefore, this is an effective deodorizing method when it is desired to quickly exert a deodorizing effect in a space where ventilation is not possible. Further, it is used for a wide range of deodorant uses such as home use, business use, and in-car use.
