◎Outline of Embodiment FIG. 1A shows an outline of an embodiment of a deodorizing construction system to which the present invention is applied, and FIG. 1B shows a deodorizing construction method by the deodorizing construction system.
In the present embodiment, the deodorizing construction method includes a measuring step S1 for measuring an odorous substance W generated from an odor generating source E in an indoor space R and a measuring step S1 as shown in FIGS. A useful substance supply step S2 for supplying a useful substance Q useful for desorbing or decomposing to the measured odor substance W to the odor generating source E and an indoor space R including the odor generating source E to heat the useful substance After the supply of the useful substance Q by the supply step S2, a bake-out step S3 in which the odorous substance W or its decomposed substance is diffused from the odor generating source E, and the air purifier 4a is operated in parallel with the bake-out step S3, and the bake-out step is performed.

And a capture step S4.

In such a technical means, it is sufficient that at least the odorous substance W can be specified in the measurement step S1, and it is preferable to calculate the amount of the odorous substance W generated from the odor generating source E. It is also possible to variably set the execution time of the bakeout step S3 based on the size of the generated amount and the volume of the indoor space R.
In addition, the useful substance Q supplied in the useful substance supply step S2 is appropriately selected as long as it is useful for desorbing or decomposing the odorous substance W attached to or impregnated in the interior material or the interior goods. It doesn't matter. The method for supplying the useful substance Q is to spray the liquid or particulate useful substance Q onto the odor generating source E (including the interior materials and interior supplies in the interior space R where the odorous substance W is scattered and adhered), or Appropriate selection such as coating may be allowed.
Furthermore, the bake-out step and 3 may be performed at least after the supply of the useful substance Q, but may be performed during the supply of the useful substance Q or before the supply.
Furthermore, the odor component capturing step S4 may be performed in parallel with the bakeout step S3, but includes a mode in which the bakeout step S3 and the odor component capturing step S4 do not start at the same time.

Next, a preferable mode of the deodorizing method according to the present embodiment will be described.
First, as one preferable mode of the deodorizing method, there is a mode further including a sealant applying step S5 of applying the sealant M to the odor generating source E after the odor component capturing step S4. In this example, even if the odorous components generated from the odorous source E are captured to the allowable level in the odorous component capturing step S4, even if a part of the odorous substance W remains in the odorous source E, the indoor space This is a mode that effectively prevents the concern that R will be dissipated.

In this example, the deodorization level in the indoor space R is inspected in the inspection step S6, and a series of deodorization processing steps (useful substance supply step S2, bakeout step S3, odor component capturing step) is performed until the deodorization level reaches an allowable level. This is a mode in which S4) is repeated.

Further, as a deodorizing construction system embodying the deodorizing construction method, as shown in FIG. 1A, a measuring means 1 for measuring an odorous substance W generated from an odor generating source E in an indoor space R, and a measuring means 1 The useful substance supply means 2 for supplying the useful substance Q useful for desorbing or decomposing the odorous substance W measured in 1. to the odor generating source E and the indoor space R containing the odor generating source E are useful.

Is operated to form an air flow for sucking off the odorous component released by the bake-out means 3, and the odorous component capturing means 4 is captured by the capturing member 4b installed inside. ..

In this example, as a preferred mode of the deodorizing construction system, as shown in FIG. 1A, a sealant applying means 5 for performing a sealant applying step S5 (see FIG. 1B) is used. There is a mode in which the inspection means 6 for adding or performing the inspection step S6 (see FIG. 1B) is provided.
Further, as a preferable mode of the odor component capturing means 4, an air flow passage for sucking the odor component in the indoor space R is formed inside the air purifier 4a, and the odor component can be captured in the air flow passage. A mode in which a filter as the capturing member 4b is arranged and a chemical liquid spraying mechanism capable of selectively spraying a chemical liquid effective for capturing an odorous component to the filter is provided inside the air purifier 4a can be mentioned. ..

◎ Embodiment 1
FIG. 2A shows an example of an indoor space to which the deodorizing method according to the first embodiment is applied.
In the figure, the interior space R is generally divided by an interior material 20 such as a floor, a ceiling, and a side wall, and a sick person is in a bedridden state for a long time at a specific site on the floor in the interior space R, or, When the body is left for a long time due to loneliness or the like, a specific portion of the indoor space R where the human body H such as a sick person or a dead body is placed becomes an odor generation source E, and an odor is generated in the indoor space R. There may be a situation where the source E emits a bad odor such as a manure odor or a body odor. The odorous substance W generated from the odor generating source E diffuses and adheres to and is impregnated with the interior material 20 such as the ceiling and side walls, and the interior article (not shown) in the interior space R. It is assumed that interior goods can also be a source of odor generation later.
The deodorizing method adopted in the present embodiment is an effective method for early reducing the indoor concentration of such malodors floating in the indoor space R.

-Measuring process-
In the present embodiment, as shown in FIG. 2B, first, the air in the indoor space R is sampled, and, for example, a precision chemical analysis of the sampled air is performed by a precision chemical analyzer (not shown), The odorous substance W contained in the R air is specified. As the fine chemical analysis device, a known analysis method such as a gas chromatograph, a gas chromatograph mass spectrometer, a high performance liquid chromatograph, an ion chromatograph, etc. is adopted.
Further, in this example, the amount of the odorous substance W generated is calculated by collecting the air in the vicinity of the odor generating source E and performing a quantitative analysis of the collected air. Here, since the calculated value of the generated amount of the odorous substance W depends on the concentration of the odorous substance W in the indoor space R, it is possible to determine the approximate deodorizing treatment time by considering the deodorizing efficiency.

-Useful substance supply process-
When the odorous substance W in the indoor space R is specified through the measurement process described above, a useful substance Q useful for desorbing or decomposing the odorous substance W attached to or impregnated in the interior material 20 is supplied. The useful substance supply step is performed (see FIGS. 3 and 4A).
Here, the useful substance Q is preferably one that exerts a deodorizing action on the odorous substance W, and the phrase “useful for desorption” means that the substance is adsorbed to the odorous substance W on the surface or inside of the interior material 20. The odorous substance W that has adhered or impregnated is easily removed from the interior material 20, and "useful for decomposing" reacts with the odorous substance W to decompose into harmless substances (for example, odorless substances). It refers to something that makes it easier.
For example, useful substances useful for human odor and carcass odor include citric acid water, chlorine dioxide water, ozone water, hydrogen peroxide water and the like.

In this example, when performing the useful substance supply step, as shown in FIG. 4A, the useful substance supply device 30 is installed in the indoor space R, and the original odor generating source E and the odorous substance W are removed. It suffices to supply the useful substance Q to the surface of the interior material 20 which is a source of the subsequent generation of odor after being adhered and impregnated.
Then, as shown in FIGS. 4A and 4B, the useful substance supply device 30 has a drug solution bottle 32 in which a drug solution containing the useful substance Q is stored in the device housing 31, and the drug solution bottle 32 The base end of the suction tube 33 is immersed in the chemical solution, a certain amount is sucked into the suction tube 33 by the pump unit 34, and the nozzle 35 connected to the tip of the suction tube 33 quantitatively sprays. ..
In addition, in this example, since the suction tube 33 has flexibility and the blowing position of the nozzle 65 can be changed, the user of the useful substance supply device 30 faces the spray target position and moves the nozzle 35. It is possible to perform the spraying operation from the nozzle 35 in the arranged state.
Further, the length of the suction tube 33 may be set uniformly if the useful substance supply device 30 is portable, but when the useful substance supply device 30 is fixedly installed, the suction tube 33 has a tube. The length varying mechanism 36 may be added to the suction tube 33 so that the length of the suction tube 33 can be adjusted so that the useful substance Q can be supplied to the entire interior space R.

The useful substance supply device 30 is not limited to the embodiment shown in FIGS. 4(a) and 4(b). For example, as shown in FIG. 4(c), the useful substance supply device 30 may be provided on the surface of the odor generating source E or the interior material 20. There is also a mode in which the useful substance Q is applied by the application tool 37 (a mode in which the brush 38 is provided on the handle 38). The application work of the useful substance Q by the application tool 37 is supplementarily performed while the operator visually confirms a portion where the supply of the useful substance Q is insufficient after performing the process by the spray type useful substance supply device 30, for example. It is preferable to perform the treatment, but it goes without saying that the treatment by the spray-type useful substance supply device 30 or the coating operation by the coating tool 37 may be individually and individually performed.

-Bakeout process-
In the present embodiment, when the useful substance supply step is completed, as shown in FIGS. 3 and 5(a), an air conditioner for heating (hereinafter abbreviated as an air conditioner) 40 and an air purifier 50 are provided in the interior space R. Is installed and the operation of the air conditioner 40 and the air purifier 50 is started.
In particular, in this example, fans 81 and 82 are installed on the ceiling and side walls of the indoor space R as necessary, and the air blown from the air purifier 50 circulates in the indoor space R and returns to the air purifier 50 again. An airflow Af to be sucked is formed.
Further, in this example, the air conditioner 40, the air purifier 50, and the fans 81 and 82 are all connected to the drive controller 100, and the drive is controlled by the controller 100.
Furthermore, in the present example, the controller 100 is connected to a temperature sensor 91 that detects the temperature in the indoor space R and a concentration sensor 92 that detects the concentration of the odorous substance W in the indoor space R, for example, a temperature sensor. The air conditioner 40 is controlled to be turned on/off under the condition that the temperature detected by 91 exceeds the treatment temperature for bakeout, and the air conditioner 40, the air purifier 50 and the fan 81 are controlled under the condition that the concentration detected by the concentration sensor 92 is below the allowable concentration. The drive of 82 is stopped.

In this example, the controller 100 also starts the operation of the fans 81 and 82 in parallel with the air conditioner 40 and the air purifier 50, whereby the entire air in the indoor space R is set at a predetermined bake-out processing temperature ( While being heated to, for example, 35° C. to 40° C., the heated air flows as an air flow Af circulating in a predetermined path.
In this state, the odorous substance W adhering to and impregnating the interior material 20 and the like in the interior space R is diffused from the interior material 20 and the like by being heated by the bake-out treatment as shown in FIG. 5B. It becomes easier to do so and is adsorbed with the useful substance Q to be desorbed from the interior material 20 or the like. Further, it reacts with the useful substance Q to be decomposed into a decomposed substance W′ and desorbed. As a result, the odorous substance W and the decomposed substance W′ that have adhered to and impregnated in the interior material 20 and the like are diffused, and move into the air purifier 50 along with the airflow Af.
In this example, the fan 81, 82 is used to form the desired air flow Af, but the present invention is not limited to this, and either the fan 81 or 82, or both of them are used. You may choose not to.

-Odor component capturing step-
In this example, the odor component capturing step is performed in the air purifier 50.
<Configuration example of air purifier>
In the present embodiment, as shown in FIG. 6A, the air purifier 50 has a substantially box-shaped clean casing 51, and the air flow Af that circulates in a part of the clean casing 31 is taken in. In addition to opening the inlet 52, an outlet 53 through which clean air is released is provided in a portion of the clean housing 51 away from the inlet 52. And an air flow passage 54 communicating with the.
A cleaning filter 60 including a plurality of filter base materials (including a filter base material for removing various pollutants existing in the indoor space R in this example) is provided in the air flow passage 54 of the clean housing 51. A fan 55 is detachably arranged, and a fan 55 is arranged on the intake port 52 side of the air flow passage 54 with respect to the cleaning filter 60, and the air flow passage 54 extends from the intake port 52 to the discharge port 53. An air flow is formed. Needless to say, a heat exchange unit (not shown) for cooling or heating may be mounted in the middle of the air flow passage 54.

<Cleaning filter>
In the present example, as shown in FIG. 6A, the cleaning filter 60 includes a pre-filter 61, a microorganism removal filter 62, a medium performance filter 63, a gas removal filter 64 in order from the intake 52 of the air flow passage 54. A HEPA filter (High Efficiency Particulate Air Filter) 65 is provided.
In this example, each of the filters 61 to 65 is detachably attached to the air flow passage 54.
(1) Pre-filter 61
This is a coarse mesh filter that mainly captures coarse dust, and is formed into a non-woven fabric using, for example, a metal mesh, metal fibers, carbon fibers or the like.
(2) Microbial removal filter 62
It mainly captures microbial particles such as bacteria, fungi, and viruses, but it can also capture allergen particles such as pollen, mites, and feces thereof similar to microbial particles.
(3) Medium performance filter 63
This is a mesh-shaped filter with a finer mesh than the pre-filter 61 and mainly captures dust of a medium size. For example, a non-woven fabric is formed by using a metal mesh, metal fibers, carbon fibers or the like. It is molded.
(4) Gas removal filter 64
This is a filter that removes odorous substances and gaseous pollutants of chemical substances, and a structure that uses an adsorbent such as activated carbon, zeolite, or ceramics that adsorbs odorous substances is adopted.
(5) HEPA filter 65
This is a mesh-shaped filter having a finer mesh than the medium-performance filter 63, and captures, for example, fine powder of activated carbon used in the gas removal filter 64. For example, a metal mesh, a metal fiber, or a carbon fiber. It is formed into a non-woven fabric by using, for example.

<Chemical solution supply mechanism>
In this example, the cleaning filter 60 serves as a useful substance Q corresponding to a gaseous pollutant such as an odorous substance or a chemical substance (for example, VOC: Abbreviation of Volatile Organic Compounds) to be removed by the gas removal filter 64, for example. A chemical liquid supply mechanism 70 capable of supplying a chemical liquid (including a deodorant etc.) is provided.
As shown in FIGS. 6A and 6B, the chemical solution supply mechanism 70 corresponds to a deodorant (chemical solution Sa corresponding to ammonia, methyl mercaptan, etc.) as a chemical solution corresponding to the removal of odorous substances and chemical substances. The chemical liquid Sb, or a plurality of odorous substances containing them, a mixed chemical liquid Sc corresponding to chemical substances, and the like) are included.

In this example, as shown in FIG. 6B, the chemical liquid supply mechanism 70 is preselected from the chemical liquid bottles 72 (specifically 72 a to 72 c) in which the various chemical liquids Sa to Sc are contained in the housing 71. (For example, a chemical solution bottle 72a in this example) is installed, and the proximal end of the suction tube 73 is immersed in the chemical solution Sa of the chemical solution bottle 72a, and the pump unit 74 sucks a certain amount into the suction tube 73, The nozzle 75 connected to the tip of the nozzle 37 sprays the gas removal filter 64 quantitatively.

<Action of clean filter>
In the cleaning filter 60 of the present embodiment, assuming that dust, pollen, fungus, bacteria, virus, chemical substance, and odor substance are present as pollutants in the air, the dust is mainly the pre-filter 61 and the medium-performance filter. 63, the HEPA filter 65 captures, fungi, bacteria, and viruses are mainly captured by the microorganism removal filter 62, and the chemical substances and odorous substances are mainly captured by the gas removal filter 64. The pollen is captured by the microorganism removal filter 62 and the medium performance filter 63.
At this time, in the present embodiment, since the corresponding chemical liquid Sa is regularly sprayed on the gas removal filter 44, the odorous substance/chemical substance removal performance is regularly restored.
Although the chemical solution Ss is sprayed onto the gas removal filter 44 in the present embodiment, the present invention is not limited to this, and the microbe removal film 62 is also compatible with the removal of microbes such as influenza virus. It goes without saying that a chemical solution supply mechanism capable of supplying (for example, a bactericidal agent for sterilizing microorganisms, an antibacterial agent for preventing the growth of microorganisms, etc.) may be provided. Further, if necessary, an appropriate chemical solution may be sprayed on the dust removal filter such as the medium performance filter 63.

<Odor component capture process>
In the present embodiment, for example, ammonia is the indoor space of the main pollutant, so that the gas removal filter 64 is adapted to spray the chemical liquid Sa suitable for ammonia. The odorous component (for example, ammonia which is the odorous substance W or its decomposed substance) that has moved along with the air flow Af taken into the air flow passage 54 from the above is captured by the gas removal filter 44 of the cleaning filter 60.
Therefore, the amount of the odorous substance W diffused in the indoor space R is gradually reduced, and the concentration of the odorous substance W is accordingly reduced.
It should be noted that in a space with a lot of odorous substances such as tobacco odor, roasted meat odor, and pet odor, a chemical solution corresponding to these odorants may be supplied. Further, when there are a plurality of pollutants such as formaldehyde, methyl mercaptan, and hydrogen sulfide, the chemical solution corresponding to each pollutant may be sprayed from each chemical solution bottle or by mixing them. ..

<Inspection process>
At this time, for example, when the operating time of the air conditioner 40 and the air purifier 50 reaches a predetermined time, the controller 100 looks at the detected concentration from the concentration sensor 92 and deodorizes the interior space R as shown in FIG. An inspection process is performed to determine whether the level has reached the allowable level (OK level).
At this time, under the condition that the deodorization level does not reach the permissible level equal to or lower than the predetermined threshold value, as shown in FIG. 3, a series of deodorization processes including a useful substance supply process, a bakeout process, and an odor component capturing process are repeated. ..
In this example, since the operation of the air conditioner 40 and the air purifier 50 is not stopped even when the useful substance supply process is re-executed, the bakeout process and the odor component capturing process are continuously performed, but the bakeout process is performed. Even if it is continued, since the absorption rate of the useful substance is improved by lowering the water content of the interior material 20, the useful substance supply process is also performed efficiently, which is preferable.
On the other hand, when the deodorization level reaches the permissible level as a result of the inspection process described above, the controller 100 stops the operation of the air conditioner 40 and the air purifier 50.

<Other functions of the cleaning filter>
Further, in the present embodiment, the filter configuration can be made according to the contamination state of the installation space of the air cleaner 50. That is, in the present embodiment, it is possible to select the chemical liquid depending on the type, physical and chemical characteristics of the contaminant in the installation space of the air purifier 50.
Therefore, even if contaminants other than the odorous substance are mixed in the indoor space R, the contaminants other than the odorous substance W can be removed.
For example, in a space where contaminants mainly containing fungi (molds) are used, a bactericidal agent, an antibacterial agent, or an antibacterial agent effective for the bacterial species is sprayed on a dust removal filter such as the microorganism removal filter 62 or the medium performance filter 63. You can do it like this. Further, in a space where there are many allergen particles such as pollen, a chemical solution for inactivating the allergen particles may be supplied to, for example, the microorganism removal filter 62. Further, in the present embodiment, the microbial removal filter 62 is sprayed and impregnated with a chemical solution such as a bactericidal agent, an antibacterial agent, and an antibacterial agent. It is preferable that it is difficult to volatilize due to Even if the chemical solution is volatilized and transported, the situation in which the chemical solution unnecessarily diffuses into the indoor space R is effectively avoided because the gas removal filter 64 is installed on the downstream side of the air flow passage 54. ..

-Sealant coating process-
When the deodorization level of the indoor space R reaches an allowable level, as a post-treatment, a sealant coating step is performed on the surface of the interior material 20 centering on the original odor generating source E.
In this example, in the sealant applying step, as shown in FIG. 7A, the applying tool 110 is applied to the surface of the interior material 20 where the odorous substance W such as the odor generating source E may partially remain. A sealant M is applied (a mode in which a brush 112 is provided on the handle 111) to seal off an odor substance W that may remain in the interior material 20.
According to this example, as shown in FIG. 7B, by performing the series of deodorizing processes (useful substance supply process, bakeout process, odor component capturing process) shown in FIG. Most of the odorous substances are released and captured by the gas removal filter 64 of the cleaning filter 60 of the air purifier 50, and the deodorization level can reach an allowable level.
However, in this example, even if a part of the deodorizing substance W remains in the interior material 20 which is the original odor generating source E, the deodorizing substance W is sealed with the applied sealant M, so The level is preferable because it can be suppressed to almost zero.

◎Example 1
This example embodies the first embodiment, takes up the phenomenon of indoor air pollution due to odorous substances derived from the human body, and particularly reveals the actual condition of odorous substance pollution in a house, and describes the pollution countermeasures in this example. This is an evaluation of the deodorizing method.
In the present embodiment, as shown in FIG. 8A, the measurement target is an apartment house (3 rooms) where the body is left unattended due to loneliness or the like and a foul odor is perceived indoors. I asked for a level.
Here, the building materials used in the same room were appropriately sampled, and the amount of each building material generated was determined by the JIS standard small chamber test method. Substances to be measured are VOC (48 substances), aldehydes (15 substances), ammonia, acetic acid, formic acid, propionic acid, butyric acid, isovaleric acid, trimethylamine, sulfur compounds (methyl mercaptan, hydrogen sulfide, methyl sulfide, methyl disulfide). Of 74 substances.

The results are shown in Fig. 8(b).
According to the figure, the following results were obtained.
(1) Some of the detected odorous substances belonged to aldehydes and fatty acids.
(2) When the amount of chemical substances generated from tatami mats and wallpapers collected from the measurement room was determined by a chamber test, the same odorous substances as indoor air pollutants were detected from the tatami mats, and the odorous substances emitted from the body were identified. Chemical data on how to do it were obtained.
(3) The amount of adsorption from the odor generating source (tatami) to the wallpaper (vinyl cloth) was small.
(4) When the deodorizing method according to the present embodiment was performed on the indoor space under conditions similar to those of the measurement target room, the following facts were found.
First, when a useful substance was supplied to the odor source and a bake-out process was performed using an air conditioner (used as a heating device) and an air purifier, it was confirmed that the amount of odor substance generated from the odor source increased. In addition, when air cleaning processing (mainly odor component capturing processing) was performed with an air purifier along with bakeout processing, it was confirmed to be extremely effective in reducing the amount of odorous substances generated from odor generating sources. It was Furthermore, it was confirmed that there was almost no concern that a foul odor was discharged outside the room when performing the deodorizing process in the indoor space.
Furthermore, if the sealant is applied to the odor generating source after performing a series of deodorizing treatments, the emission of the odorous substance from the odor generating source is better than in the case where the sealant is not applied. It was also confirmed to be surely suppressed.
As described above, the present embodiment is extremely effective in solving the problem of odor pollution of an accidental property in a house (for example, a property in which the body is left unattended due to lonely death, etc. and a foul odor is perceived indoors) in a short period of time. It is understood that
