Description

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

  In recent years, with increasing awareness of deodorization and deodorization in the living environment, there has been a demand for a deodorization method and a deodorization apparatus that can easily, quickly and effectively remove or reduce air containing odor components such as malodors.

  The odor components that make up the air, including odor components that occur in daily life, include various components derived from human sweating, excretion, cooking, pets, garbage, etc., and are soluble in water (water soluble In addition to odor components, many components that are hardly soluble or insoluble in water (hydrophobic odor components) are also contained.

  Examples of water-soluble odor components 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, butyric acid, etc. Examples include fatty acid components, lower aldehyde components such as acetaldehyde, formaldehyde, etc., 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). Intermediate to higher aldehyde components such as hexanal, octanal, nonanal, nonenal and the like.

  Conventionally, a stationary type (stationary type) has been widely used as an indoor deodorant. However, in this type of deodorant, it takes a certain amount of time to develop the deodorant effect because the air containing the odor component exerts the deodorant effect by contacting the deodorant with natural convection. End up. Therefore, when it is desired to deodorize in a short time, it has been necessary to adopt a method of ventilating to remove odor components in the air or sprinkling a spray type deodorant.

  Although the following deodorizing methods have been reported in addition to the above-described stationary type (stationary type) deodorants, they are not always satisfactory.

  Japanese Patent Application Laid-Open No. H10-228561 describes a method of removing the odorous components by aerating air containing odorous components to the site where the water-soluble odorous components are removed and the portion where the hydrophobic odorous components are removed. In this device, the deodorizing effect is improved by positively ventilating the odor component to the odor removal site, but the device is necessarily complicated and large because it is necessary to provide two odor removal sites. Moreover, the solution of glutaraldehyde and citric acid is only described as a water-soluble odor component removal material, and it is described that a solid deodorization material such as activated carbon is exclusively used for the hydrophobic odor component removal material. Stay on.

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

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

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

  An object of this invention is to provide the deodorizing method and deodorizing apparatus which can remove or reduce the said odor component easily and quickly and effectively from the air containing a water-soluble odor component and a hydrophobic odor component.

  As a result of intensive studies to solve the above-mentioned problems, the present inventor positively brings the air containing the odor component into contact with the deodorant liquid (particularly, the aqueous liquid composition containing the deodorant component). It has been found that odor components can be removed or reduced simply, quickly and effectively.

  Specifically, by bringing the air containing the odor component into contact with the aqueous liquid composition containing the deodorant component, in other words, the aqueous liquid composition containing the deodorant component is replaced with the air containing the odor component. The above problem can be solved by aeration.

  In particular, hydrophobic odor components such as hydrogen sulfide, methyl mercaptan and intermediate to higher aldehydes were generally considered to have low solubility in water and a low deodorizing effect. However, the air containing the hydrophobic odor components was deodorized. It has been found that the deodorizing effect can be dramatically improved by bringing it into contact with an aqueous liquid composition containing an agent component. Further research based on this knowledge has led to the completion of the present invention.

  The deodorizing method and the deodorizing apparatus of the present invention can remove or reduce the odor component easily, quickly and effectively from air containing both a water-soluble odor component and a hydrophobic odor component. In particular, hydrophobic odor components such as hydrogen sulfide, methyl mercaptan, intermediate to higher aldehydes were considered to have a low deodorizing effect due to low solubility in water, but are expected to be obtained by using the deodorizing method of the present invention. These components can be drastically removed or reduced to the outside.

  In the deodorizing method and deodorizing apparatus of the present invention, an aqueous liquid composition containing various deodorant components can be used as a deodorizing liquid. In particular, when removing hydrophobic odor components, plant extracts, quaternary ammonium salts, heterocyclic compounds, metal compounds, clathrate compounds, amphoteric compounds, adsorbents (fine powder), metal complexes of amino acids, An aqueous liquid composition containing a deodorant such as an acidic compound or a basic compound is preferred.

At this time, even when a colored liquid in which a pigment or the like is dissolved is transparent, it is easy to determine the replacement time. For example, if a pH indicator component is blended, the color change accompanying the change in pH caused by the reaction of the odor component with the deodorant can be visually confirmed, and it can be used as a guideline for the replacement timing of the deodorant solution. It is. Furthermore, by adding a volatile solvent to the deodorizing liquid or increasing the opening area of the lid of the apparatus, the amount of the deodorizing liquid can be reduced over time, and can be used as a guideline for replacement timing.

Specifically, it is as follows.
(1) The test tube method was used as the test method.
(2) The sample shown in Table 1 was used as the test sample.
(3) The application method was performed by a stationary method, and the test container used was a 5 L cocked air bag.
(4) The test procedure is as follows. An air bag containing a test sample and air containing an odor component and an air bag containing only air containing an odor component (blank) 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 concentration of the odor component of the test sample and the blank was measured over time, and applied to the following formula to calculate the deodorization rate (%).

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.
