Conventional chlorine dioxide gas generators are premised on being used stationary at a specific place, and are not designed to be used by moving to various places. Therefore, there is a demand for a chlorine dioxide gas generator that is poor in portability and can be used in various places and situations.

The present invention has been made in view of the above circumstances, and its object is to provide a chlorine dioxide gas fumigation kit that is highly portable and can be used in various places and situations.

The characteristics of the chlorine dioxide gas fumigation kit according to the present invention are:
A chemical that generates chlorine dioxide gas when dissolved in water and a water-reactive exothermic agent are enclosed, and a water inflow hole is formed on the bottom surface and a steam containing chlorine dioxide gas on the top surface. The present invention is provided with a can container in which a jet hole is formed, and a moisture-proof and heat-resistant bag that accommodates the can container in a sealed state and whose upper part is openable when in use.

According to this configuration, when the can container is used, the upper portion is opened and water is injected into the can container using the bag body as a container, whereby water is supplied to the inside from the inflow hole in the bottom surface of the can container. As a result, the chemical dissolves in water to generate chlorine dioxide gas, and the action of heat from the exothermic agent that reacts with the water further promotes the generation of chlorine dioxide gas, and the high-temperature steam jets out to diffuse the gas into the room. Prompted. Therefore, unlike conventional chlorine dioxide gas generators, it is possible to generate high-concentration chlorine dioxide gas without the need for a heating device or power supply, etc., so it is highly portable and can be used in various places and situations. can be used in

Furthermore, according to this configuration, since water is supplied to the inside of the can through the inflow hole in the bottom of the can, the entire amount of water does not immediately react with the medicine and exothermic agent, but gradually flows into the can. As a result, the generation of chlorine dioxide gas progresses gently. In addition, since the water flowing from the bottom of the can is gradually absorbed by the exothermic agent, a necessary amount of water is ensured for disintegration of the agent. In addition, the water that has not flowed into the can remains outside the can, providing a cooling effect that suppresses the consumption of water due to the generation of excess water vapor, which is necessary for the reaction to generate chlorine dioxide gas. A sufficient amount of water is ensured to dissolve the drug.

In the chlorine dioxide gas fumigation kit according to the present invention, it is preferable that the compounding ingredients of the agent include a chlorite, a low hygroscopic acidic agent, and a powder of a halogen-based oxidizing agent.

According to this configuration, the water pumped into the bag is brought into an acidic condition by the acidic agent, and under this acidic condition, the chlorite powder and the halogen-based oxidizing agent dissolve and react in the water. Chlorine dioxide gas is generated efficiently. Since the acidic agent has low hygroscopicity, it is excellent in storage stability.

In the chlorine dioxide gas fumigation kit according to the present invention, it is preferable that the compounding component of the agent further includes a foaming agent.

According to this configuration, the disintegration of the medicine is promoted, and each component becomes easily soluble in water.

In the chlorine dioxide gas fumigation kit according to the present invention, the exothermic agent preferably contains metal powder as a main component, and the metal powder is packed in a water-permeable packaging material.

According to this configuration, as compared with an exothermic agent whose main component is only quicklime, it does not cause a rapid temperature rise, it is possible to suppress rapid generation of chlorine dioxide gas, and it is difficult for quicklime to disperse in water. Therefore, the outflow of alkali, which is a factor that inhibits the generation of chlorine dioxide gas, is suppressed.

In the chlorine dioxide gas fumigation kit according to the present invention, it is preferable that the bag can stand on its own when used.

According to this configuration, since the can container is maintained in an upright position during use, water can easily flow in through the inflow hole. It becomes possible.

In the chlorine dioxide gas fumigation kit according to the present invention, it is preferable that the bag can be used as a container for storing pumped water during use.

According to this configuration, there is no need to separately prepare a container for containing the can container and drawing water, and the bag can be used simply by drawing water, which is convenient.

In the chlorine dioxide gas fumigation kit according to the present invention, it is preferable that the bag has a light-shielding property and also serves as an exterior material.

According to this configuration, the chlorine dioxide gas fumigation kit according to the present invention can be distributed as it is, which leads to resource saving.

In the chlorine dioxide gas fumigation kit according to the present invention, it is preferable to provide an openable and closable zipper part on the upper part of the bag.

According to this configuration, it is possible to easily switch between the sealed state and the unsealed state. Furthermore, after use, it can be discarded simply by sealing the chuck part, and water is prevented from entering after disposal, so the generation of hydrogen gas etc. is prevented by preventing the reaction between the remaining exothermic agent and water. be able to.

In the chlorine dioxide gas fumigation kit according to the present invention, it is preferable that the bag contains a drawing container for drawing water at the time of use.

According to this configuration, a predetermined amount of water can be easily supplied to the bag, which is convenient.

In the chlorine dioxide gas fumigation kit according to the present invention, it is preferable that the drawing container is made of paper, folded into an envelope shape and enclosed in the bag.

As in this configuration, by making the drawing container made of paper, it is possible to freely set the size to the specified water volume at low cost, and unlike plastic, etc., it is easy to prepare different sizes. Become. Furthermore, it can be folded compactly and packed in a bag, and is environmentally friendly when it becomes waste.

It is an external perspective view of a chlorine dioxide gas fumigation kit. It is an explanatory view showing the composition of the chlorine dioxide gas fumigation kit. FIG. 4 is an explanatory view showing the state of chlorine dioxide gas generation in the chlorine dioxide gas fumigation kit during use.

An embodiment of a chlorine dioxide gas fumigation kit according to the present invention will be described with reference to the drawings.

(Chlorine dioxide gas fumigation kit)
As shown in FIGS. 1 and 2, a chlorine dioxide gas fumigation kit 1 in this embodiment includes a cylindrical can container 2, a drawing container 3 for drawing water when used, and a bag 4. , a can container 2 and a drawing container 3 are enclosed in a bag body 4. - 特許庁

The can container 2 contains a chemical agent 5 that generates chlorine dioxide gas when dissolved in water and a water-reactive exothermic agent 6. A water inflow hole H1 is formed in the bottom surface 21 of the can container 2. , and steam ejection holes H2 containing chlorine dioxide gas are formed in the top surface 20. As shown in FIG.

The compounding components of the chemical agent 5 include, for example, a composition containing a chlorite, a low hygroscopic acidic agent, and a dusting agent of a halogen-based oxidizing agent. The water pumped into the bag body 4 flows into the can container 2 from the inflow hole H1, and becomes an acidic condition due to the acidic agent dissolved in the can container 2. Under these acidic conditions, chlorite and halogen-based oxidation occur. Chlorine dioxide gas is generated by reacting with the agent.

Usable chlorites include, for example, powders such as sodium chlorite, potassium chlorite, lithium chlorite, and calcium chlorite. The acidic agent preferably has low hygroscopicity in view of storage stability so as to avoid becoming acidic during storage (before the start of use). Acidic agents that can be used include, for example, succinic acid, malonic acid, and phthalic acid. Moreover, usable halogen-based oxidizing agents include, for example, dichloroisocyanurate, trichloroisocyanurate, bleaching powder, and the like.

As the exothermic agent 6, it is preferable to use an exothermic agent which does not cause a rapid temperature rise and alkalinization as compared with an exothermic agent whose main component is only quicklime. Examples of such an exothermic agent 6 include those containing metal powder as a main component, and the metal powder being filled in a water-permeable packaging material. As a specific example, it is possible to use Morian Heat Pack manufactured by Kyodo Co., Ltd., in which a water-permeable packaging material is filled with a mixture of aluminum powder and quicklime.

As a compounding component of the drug 5, a configuration may be adopted in which a foaming agent such as sodium bicarbonate is further included. This is because the action of the foaming agent promotes the disintegration of the drug 5, making each component more soluble in water.

In this embodiment, only one inflow hole H1 is formed in the central portion of the bottom surface 21 of the can container 2, and only one ejection hole H2 is formed in the central portion of the top surface 20 of the can container 2. However, it is not limited to this configuration, and the number and arrangement thereof may be changed as appropriate.

Although the material of the can container 2 is not particularly limited, for example, a known tin can can be used.

The bag 4 is moisture-proof and heat-resistant, and is configured to house the can container 2 in a sealed state and to be opened at the top when used.

In this embodiment, an openable and closable chuck portion 40 is provided on the upper portion of the bag body 4 . This makes it possible to easily switch between the sealed state and the unsealed state. Furthermore, after use, disposal is possible only by sealing the chuck part 40, and water is prevented from entering after disposal. Therefore, generation of hydrogen gas and the like is suppressed by preventing the reaction between the remaining exothermic agent 6 and the like and water. can be prevented.

In addition, it is desirable that the bag 4 has a light-shielding property and also serves as an exterior material and as a container for storing the pumped water. As a result, the chlorine dioxide gas fumigation kit 1 according to the present invention can be distributed as it is, which leads to low cost and resource saving. As such a bag body 4, for example, one provided with a metal sheet such as aluminum foil can be used.

The bag 4 is desirably constructed so as to be able to stand on its own while enclosing the can container 2 therein. As a result, the can container 2 is maintained in an upright position during use, so that water can easily flow in from the inflow hole H1. It becomes possible.

The drawing container 3 in this embodiment is made of paper, is folded into an envelope shape, and is sealed in the bag body 4 . By making the drawing container 3 made of paper, it is possible to freely set the size to a specified water volume at a low cost, and unlike a container made of plastic or the like, it is easy to prepare different sizes, and the cost is extremely low. becomes. Furthermore, it can be folded compactly and packed in the bag body 4, and it is environmentally friendly when it becomes a waste.

However, the drawing container 3 does not necessarily have to be made of paper, and is not particularly limited as long as it can draw water. In addition, it is desirable that the drawing container 3 is configured to be able to measure water. The minimum amount of water required to generate the required amount of chlorine dioxide gas may be set.

(How to use the chlorine dioxide gas fumigation kit)
As shown in FIG. 3, first, the chuck portion 40 of the bag 4 is opened, and the container 3 is taken out. Then, the bag body 4 is arranged at a predetermined place and made to stand on its own. At this time, the can container 2 in the bag body 4 is made to take a standing posture.

Next, a predetermined amount of water W is poured into the bag body 4 from the opening of the chuck portion 40 using the drawing container 3 .

The poured water W flows into the inside through the inflow hole H1 of the bottom surface 21 of the can container 2 and comes into contact with the medicine 5 and the exothermic agent 6 .

The water W dissolves the drug 5, and the acidic agent creates an acidic condition. Chlorine dioxide gas G is generated by reaction between chlorite and a halogen-based oxidizing agent in water W under these acidic conditions. At the same time, the water W also reacts with the exothermic agent 6 . The exothermic agent 6 reacts with the water W to generate heat, thereby promoting the generation of chlorine dioxide gas G and dissipating the generated chlorine dioxide gas G into the room together with high-temperature steam through the ejection holes H2 of the can container 2. Let

In this embodiment, the water W is supplied to the inside through the inflow hole H1 in the bottom surface 21 of the can container 2. Therefore, when the water W that has flowed in reaches a predetermined level of the can container 2, the inflow temporarily stops. It reacts with part of the drug 5 and exothermic agent 6 . When the reaction causes the water level to drop, the water W is replenished. In other words, since the entire amount of water W does not immediately flow into the can container 2, the exothermic agent 6 immediately absorbs a large amount of water, resulting in a shortage of water necessary for the disintegration of the agent 5. phenomenon does not occur. Although the exothermic agent 6 may exist in a weight ratio of about 10 times or more than that of the agent 5, according to the present embodiment, the phenomenon that the water required for the disintegration of the agent 5 is insufficient does not occur. Therefore, the amount of water required to generate all of the chemical agent 5 as chlorine dioxide gas G is ensured during fumigation.

In addition, the water W that has not flowed into the can container 2 stays outside the can container 2, and the water W provides a cooling effect, suppressing the amount of steam generation and reducing the amount of water consumed. The amount of water in the system necessary for generating chlorine dioxide gas G from the total amount of is secured.

[Other embodiments]
In the above-described embodiment, for the sake of convenience, a construction is shown in which the pumping container for pumping water at the time of use is preliminarily sealed in the bag, but the construction is not limited to this. It is not necessary to include a pumping container if there is some other means by which the bag can be supplied with a predetermined amount of water.

Although the present invention has been described with reference to the drawings as described above, the present invention is not limited to the configuration of the drawings, and can be implemented in various forms without departing from the scope of the present invention. It goes without saying that we can.
