Description

The present invention relates to a soot-type volatilizer, a soot-type space treatment apparatus and a space treatment method using the soot-type volatilizer.
This application claims priority based on Japanese Patent Application No. 2011-102352 filed in Japan on April 28, 2011 and Japanese Patent Application No. 2011-179604 filed on August 19, 2011 in Japan. , The contents of which are incorporated herein.

Various methods have been proposed as techniques for releasing and diffusing (hereinafter referred to as “volatilization”) active ingredients in a wide space. For example, a method in which the active ingredient is atomized and ejected is performed.
As an example of this, an agricultural chemical spraying method is disclosed in which an apparatus using a motor or a gasoline engine as a drive source is used in agriculture, and a chemical solution is sprayed from a spray nozzle in a pressurized state by a compressor (see, for example, Patent Document 1). According to this method, the agricultural chemical can be uniformly distributed in the house.

Also, in general households, smoke is treated with fumigants (fumigants) to control pests, sanitary pests such as flies, mosquitoes and cockroaches, mold, bacteria, etc. To be done.
The smoke agent is a solid preparation mainly composed of an exothermic base mixed with various combustion agents, foaming agents, and the like, and an active ingredient. As the exothermic base, nitrocellulose, azodicarbonamide, p, p′-oxybis (benzenesulfonylhydrazide), N, N′-dinitrosopentamethylenetetramine and the like are generally used.
When the smoke agent is heated at the time of use, the exothermic base burns or decomposes to generate smoke (gas and fine particles), and the active ingredient is volatilized in the air by the action of the smoke and heat. Therefore, the active ingredient can be spread throughout the space in a short time, and the space can be processed.

  The soot agent is heated by direct heating method in which a part of the soot agent is ignited to burn the soot agent, or by the hydration reaction heat of a heating agent such as calcium oxide. An indirect heating method for heating to a temperature is used. For example, a smoke composition containing an exothermic base such as azodicarbonamide and an active ingredient is heated by an indirect heating method using the heat of hydration reaction of calcium oxide, etc., and generated by self-combustion of the exothermic base. Smoke devices that volatilize active ingredients with smoke (gas and fine particles generated by thermal decomposition) have been proposed and put into practical use (see, for example, Patent Documents 2 to 3).

  On the other hand, a heat evaporating agent that heats a liquid composition in which an active ingredient is dissolved in a solvent to evaporate the active ingredient has been proposed. Such a heat transpiration agent is housed in a device equipped with a liquid absorption wick, and the liquid absorption wick absorbs the liquid and gradually heats the active ingredient by heating the liquid absorption wick. The heating temperature is lower than that in the case of the smoke agent, and is usually 135 ° C. or lower (see, for example, Patent Documents 4 to 5).

Japanese Patent Laid-Open No. 61-224928 Japanese Patent Publication No.58-28842 Japanese Patent Publication No.59-49201 Japanese Patent Laid-Open No. 7-69805 JP 2009-232915 A

However, the method of Patent Document 1 is not a simple method because the apparatus is large and is not particularly suitable for home use.
Smoke agents containing exothermic bases such as azodicarbonamide as described in Patent Documents 2 to 3 are excellent in volatilizing power of active ingredients, but are contaminated in the space by white sediment due to generated smoke. There is a problem that causes
In addition, since the heat transpiration agent of the type described in Patent Documents 4 to 5 does not contain an exothermic base, the contamination of the space is difficult to occur, but the volatilization of the active ingredient is gradual. The active ingredient does not spread enough. Therefore, there is a problem that the obtained effect is weak. In addition, since the volatilized state of the active ingredient is not visible like smoke generated by heating the smoke smoke agent, there is also a problem that it is difficult for the user to obtain an effective feeling.

When the water content is 50% by mass or less, the specific heat of the steam generated during heating is sufficiently small, so that a thick smoke is likely to be generated and the visibility is improved.
However, what is necessary is just to set content of water suitably according to a use and the kind of (B) component. For example, when a microbial deactivation component is used as the component (B), the content of water is preferably 1 to 50 mass%, more preferably 2 to 20 mass%, based on the total mass of the smoke-type volatilizing agent. -10 mass% is further more preferable, and it does not need to contain water. (B) When using a fragrance | flavor component as a component, 10-90 mass% is preferable with respect to the total mass of a smoke-type volatilizer, 30-80 mass% is more preferable, and 50-70 mass% is preferable.

From the viewpoint of the above, the mass ratio represented by (A) component / water is preferably 20/80 to 100/0, more preferably 20/80 to 90/10, but desired effects, etc. What is necessary is just to determine suitably according to.
Among them, the density of the smoke generated, control of the amount of smoke generated and the duration of smoke generation, and the coexistence of the amount of volatilization of the component (B) into the space and the reduction of pollution are achieved. Since it is easy, it is more preferable that it is 30 / 70-98 / 2 by the mass ratio represented by (A) component / water, It is further more preferable that it is 50 / 50-98 / 2, 80 / 20-95 Particularly preferred is / 5.

The smoke type volatilizer of the present invention may contain other components other than the above components (A) and (B) and water as long as they do not impair the effects of the present invention. Examples of the other components include surfactants, preservatives, gelling agents, excipients, and the like.
The surfactant is not particularly limited as long as it is usually used for pharmaceuticals, quasi drugs, cosmetics, miscellaneous goods, etc., and is nonionic from the viewpoint of solubility and dispersibility in the component (A). A surfactant is preferred. Specifically, polyoxyethylene hydrogenated castor oil, polyoxyethylene alkyl ether, polyoxyethylene polyoxypropylene alkyl ether, sorbitan fatty acid ester, glycerin fatty acid ester, propylene glycol fatty acid ester, polyethylene glycol fatty acid ester, polyglycerin fatty acid ester, Examples include polyoxyethylene glycerin fatty acid ester, polyoxyethylene sorbitan fatty acid ester, and sucrose fatty acid ester.
The smoke type volatile agent of this invention can be prepared by mixing said each component.

≪Spatial processing method≫
As described above, the smoke-type volatilizer of the present invention is heated at 150 to 450 ° C. to generate white smoke and the component (B) is volatilized. When the smoke-type volatile agent of the present invention is heated in a space such as a house or a vehicle, the component (B) is volatilized in the space in a short time by the smoke-like material and is subjected to space treatment (effective Various effects due to the ingredients are exhibited).
The heating temperature of the smoke type volatile agent is 150 to 450 ° C, preferably 170 to 400 ° C, and more preferably 190 to 400 ° C. By heating at 150 ° C. or higher, the generated vapor of component (A) can be ejected in the form of smoke, and component (B) can be diffused throughout the space to be treated. Within the above range, the higher the heating temperature, the shorter the time for the component (B) to diffuse throughout the space, and the wider the diffusion range. When heating temperature exceeds 450 degreeC, there exists a possibility that the quantity which volatilizes (B) component thermally and volatilizes in an effective state (undecomposed state) may reduce (volatilization efficiency falls).

The soot-type volatilizer is preferably heated by an indirect heating method because of its excellent anti-contamination effect. The indirect heating method is a method known as one of the heating methods for smoke agents, and the temperature (thermal energy) required for the pyrolysis of the exothermic base without burning the smoke agent is changed to the heat transfer part ( For example, it is a simple method of supplying via the wall (side wall or bottom wall) of the container containing the smoke agent, the space of the container, or the like. That is, in the case of the present invention, it is preferable to supply the temperature (thermal energy) necessary for vaporizing the component (A) via the heat transfer section without burning the smoke-type volatile agent.
The heating unit is not particularly limited, and a heating unit conventionally used for the indirect heating method can be used. For example, a method in which a substance that generates heat upon contact with water is brought into contact with water and the reaction heat is used, and a metal and a metal oxide or an oxidizer having a lower ionization tendency than the metal are mixed (for example, iron powder and an oxidizer ( For example, a method of using heat generated by the oxidation reaction thereof, a method of using heat generated by an electric force such as a heating wire (for example, a hot plate), and the like. Among these, from the viewpoint of practicality, a method of bringing a substance that generates heat upon contact with water into contact with water and utilizing the reaction heat thereof is preferred, and a method of utilizing the reaction heat between calcium oxide and water is more preferred.
Examples of substances that generate heat upon contact with water include calcium oxide, magnesium chloride, aluminum chloride, calcium chloride, and iron chloride. For example, when calcium oxide and water are reacted, heat of about 200 to 400 ° C. is generated.
Heating by the indirect heating method can be carried out, for example, by incorporating the smoke type volatilizing agent of the present invention into a container conventionally used in an indirect heating type smoke device.

Moreover, it is preferable that the temperature of the smoke-type volatile agent is reached in a short time as much as possible to reach the set temperature by heating. Specifically, it is preferable to heat the soot-type volatile agent so that the surface of the heat transfer section reaches the desired set temperature in a short time. More specifically, the heating is performed so as to reach the set temperature, preferably within 120 seconds, more preferably within 60 seconds, after starting heating by each of the above reactions or heating wires. By controlling the heating rate in this way, the thermal decomposition of the component (B) is further suppressed, and the effect of the active component is enhanced.
Furthermore, it is preferable to hold an arbitrary set temperature for as long as possible. Specifically, heating is performed so as to maintain the set temperature for 90 seconds or more, more preferably for 150 seconds or more. By maintaining the set temperature in this manner, the smoke generation duration is increased, and the component (B) can be diffused throughout the space to be processed, or the volatilization amount of the component (B) into the space can be further increased. it can.
What is necessary is just to set the said preset temperature, a heating rate, and holding time suitably according to the kind of (B) component. When calcium oxide is used as a substance that generates heat upon contact with water, it can be controlled by selecting the ratio of calcium oxide to water, the amount of calcium oxide used, and the product grade of calcium oxide. It can also be controlled by the capacity or material of the container containing the smoke type volatile agent.

What is necessary is just to set the usage-amount of a soot-type volatilizer suitably according to the floor area made into object. For example, when a microbial deactivation component is used as the component (B), 0.1 to 2.0 g is preferable per 1 m ² , and 0.2 to 1.5 g is more preferable.
The treatment time (time for sealing the target space after the start of heating) is not particularly limited, preferably 10 minutes or more, and more preferably 1 hour or more.

≪Smoke type space treatment equipment≫
The smoke type space treatment device of the present invention is such that the smoke type volatile agent of the present invention and a heat generating part that generates heat of 150 to 450 ° C. are arranged via a heat transfer part.
The configuration of the soot-type space treatment device of the present invention is the same as the configuration of a known indirect heating type soot device except that the soot-type volatilizer of the present invention is used instead of the soot agent. It is done.
One embodiment of the smoke type space processing device of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a schematic cross-sectional view showing the configuration of the smoke type space processing device 1 of the present embodiment.
The smoke-type space processing device 1 includes an outer container 10, an inner container 20 provided inside the outer container 10, a heat generating unit 30 provided between the outer container 10 and the inner container 20, and an inner container 20. And the soot-type volatilizer 40 accommodated in the container.
As the smoke type volatile agent 40, the smoke type volatile agent of the present invention is used.

The heat generating portion 30 is formed by filling a substance that generates heat upon contact with water (for example, calcium oxide). The filling amount of the substance can be determined in consideration of the amount of heat necessary for generating steam from the smoke-type volatile agent 40 and the like. Examples of the substance that generates heat upon contact with water include the same substances as those described in the explanation of the space treatment method, and calcium oxide is preferable.
The ratio of calcium oxide and water may be appropriately determined in consideration of the density of the generated smoke, the amount of smoke generated, the duration of smoke generation, the amount of volatilization of component (B), and the like.
In addition, although the example filled with the substance which generate | occur | produces heat in contact with water was shown here, this invention is not limited to this. For example, a partition material may be arranged in the heat generating portion 30 to form a plurality of independent compartments, and each compartment may be filled with a metal and a metal oxide or oxidizer having a lower ionization tendency than the metal.

The inner container 20 functions as a container that houses the smoke-type volatile agent 40, and also functions as a heat transfer unit that transmits the heat energy generated in the heat generating unit 30 to the smoke-type volatile agent 40.
The material of the inner container 20 only needs to have heat conductivity, and examples thereof include metal, plastic, paper, and the like.
The inner container 20 may be in contact with or separated from the heat generating unit 30.

The outer container 10 includes a main body 12, a lid portion 14, and a bottom portion 16.
Each material of the main body 12, the lid portion 14, and the bottom portion 16 has heat resistance that does not cause deformation due to heat generated in the heat generating portion 30 or high-temperature steam generated from the smoke-type volatilizing agent 40, For example, metal, ceramic, paper, etc. are mentioned.
The main body 12 has a substantially cylindrical shape, the inner diameter thereof is larger than the outer diameter of the inner container 20, and the height is higher than the height of the inner container 20. Thereby, when the inner container 20 is installed in the outer container 10, a gap is formed between the side wall and the bottom wall of the inner container 20.
The lid portion 14 has a hole through which steam passes, and examples thereof include a mesh, a punching metal, and a lattice frame.
The bottom portion 16 is made of a material having pores that are permeable to water and do not permeate the material constituting the heat generating portion 30 (the material that generates heat upon contact with water), such as a nonwoven fabric or a mesh. As a result, water can enter the heat generating portion 30 from the bottom portion 16 during use to generate heat.
In addition, the structure of the bottom part 16 is determined according to the structure of the heat generating part 30. For example, when the heat generating part 30 is filled with a metal and a metal oxide or an oxidizing agent having a smaller ionization tendency than the metal, The structure of the bottom 16 may be impermeable to water.

A space processing method using the smoke-type space processing device 1 will be described.
First, the smoke type space processing apparatus 1 is installed in the target space. Next, the heat generating unit 30 generates heat according to the mechanism of the heat generating unit 30. For example, when the heat generating part 30 filled with calcium oxide is provided, the bottom part 16 of the outer container 10 is immersed in water. Thereby, the water which infiltrated from the bottom part 16 reacts with calcium oxide in the heat generating part 30, and heat of about 200 to 350 ° C. is generated.
At this time, the temperature of the inner bottom center portion 22 of the inner container 20 can be set to any value within a short time, preferably within 120 seconds, more preferably within 60 seconds, from the time when the bottom 16 of the outer container 10 is immersed in water. It is preferable to control to reach the set temperature. In addition, it is preferable to maintain the temperature of the inner bottom center portion 22 at an arbitrarily set temperature for 90 seconds or more (more preferably 150 seconds or more). The temperature of the inner bottom center portion 22 can be controlled by adjusting the amount of water that reacts with calcium oxide.
And the heat which the water which infiltrated from the bottom part 16 reacted with calcium oxide in the heat generating part 30 is transmitted to the soot-type volatilizer 40 through the side wall and the bottom wall of the inner container 20, and the soot-type volatilizer 40 The temperature rises and (A) component vapor is generated. The component (B) diffuses through the hole of the lid 14 together with the generated vapor. And the effect by an effective component can be acquired because (B) component diffuses in object space. Moreover, the vapor | steam of (A) component is visually recognized like white smoke, and a user can obtain an effective feeling. As described above, by using the smoke-type space processing device 1, the space processing can be easily performed.

  The above-described embodiment is a so-called indirect heating type smoke processing apparatus, for example, a volatilizing agent impregnated body (for example, a liquid absorbent core) or a molded body, and a heat transfer section disposed separately from the molded body. May be provided.
