Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a simple deodorizer using ozone that is applied to fields such as general households.

traditional techniques Recently, ozone deodorization has been in the spotlight.

Such a deodorizing device is an ozone generator 2 anti-ventricular.

Not only does it require equipment to decompose excess ozone, making the equipment larger and increasing equipment costs, but since high-concentration ozone is used, the area around the ozone flow path must be made of ozone-resistant material. do.

Its field of use was limited to industrial use. but.

Since the deodorizing effect of ozone is remarkable, fields of use other than those mentioned above should be developed, and there has been a strong desire to develop a deodorizer that is small and simple and can be used in general households.

Problems to be Solved by the Invention The object of the invention is to make an ozone deodorizing device smaller and simpler so that it can be applied in general homes, etc., and to expand its field of use.

Means for Solving the Problems An ozone generator and a deodorizing filter containing deodorizing particles in a breathable box, or a space made up of the filter and a non-ventilated body and for housing the ozone generator. It consists of a deodorizer body installed.

The ozone generator is installed inside the space of the main body so as to be able to generate ozone.

Ozone generated by the ozone generator in the space of the simple deodorizer is generated by the heat generated by the device.

It passes through the deodorizing filter while decomposing and reacting, becoming oxygen and diffusing to the outside. As this diffusion occurs, malodorous air from outside is taken into the space through the deodorizing filter, and the malodorous components are oxidized and decomposed to become odorless through the space and the deodorizing filter, and diffuse to the outside. Since diffusion and uptake are performed in this way, the sealed space around the deodorizer is circulated over time, and deodorization progresses.

Example Embodiments of the invention will be described in detail with reference to FIGS. 1 to 5.

1 to 4 are explanatory diagrams of embodiments of the present invention, and FIG. 5 is a plan view of the ozone generating electric field device.

In the figure, 1 is an ozone generator, and 5 is a deodorizing filter.

8 is a deodorizer main body, and 9 is a simple deodorizer.

The ozone generator 1 has an ozone generator 1, an ozone generator electric field device 10, and an ultraviolet lamp (2) for generating ozone.

The ozone generating electric field device 10 has a t'r-electrode Ba, 13b buried within an insulating layer, and when a high voltage from an AC power source 14 is applied to this via an electric wire 15, the area near the surface of the layer ν is A silent discharge occurs in the gas in the space, and ozone is generated from the oxygen in the gas.

The ultraviolet lamp 11 has a wavelength of 200 nm or less, especially 18
It strongly emits light with a wavelength of 5 nm, which is absorbed by oxygen in the air and becomes ozone. In the figure, 11a is an arc tube section, and ub is a socket section. The deodorizer main body 8 includes a deodorizing filter 5 in which deodorizing granules 4 to which a granular carrier 8P (to be described later) is added and treated with a catalyst for decomposing niosin are removably built into an air-permeable box 2. Alternatively, the filter 5 and an insulating non-gas-permeable body 6t such as a ceramic plate are constructed, and a space 7 having a required volume is formed in which the ozone generator 1 is housed and ozone is generated. That is, the simple deodorizer 9 of the present invention has the ozone generator 1 in the space 7 of the main body 8.
This is an integrated system that is enclosed and sealed so that it can generate ozone.

The simple deodorizer shown in Fig. 1.8.4 has a main body 8 consisting of a deodorizing filter, a -5 and a non-ventilating body 6, and an electric field device 10 or an ultraviolet lamp (■) is used to generate ozone in the space 7 formed thereby. It is possible to arrange it. The simple deodorizer shown in Figure 2 is
The main body 8 is composed of a deodorizing filter 5, and an electric field device 10 is disposed within the space 7. The material, shape, size, etc. of the granular carrier 3 are not particularly limited. For example, regarding materials, ceramic, zeolite, activated carbon,
There are m stones, diatomaceous earth, white clay, etc., and the shape t is 9
ball.

Examples include a cylindrical bolt, an irregular shape, a plate, a needle shape, etc., and the appropriate size of these is from several square meters to several grammes. Suitable catalysts include transition metal oxides such as nickel oxide and copper oxide, noble metals such as platinum, or mixtures thereof.

In FIG. 6, the simple deodorizer 9 using the electric field device of the present invention is constructed such that when a high voltage from the AC power supply 14 is applied to the electrodes 13a and 13b of the electric field device 10, the space near the surface of the insulating layer sphere is A silent discharge occurs in the gas in the area.

This generates ozone from the oxygen in the gas.

0! + s-→20 0+Oz+M→O, +M (M is the eighth substance such as N2) The generated ozone is transferred to the generated ozone by the thermal and kinetic energy obtained from the discharge.

Within a predetermined period of time, the oxygen passes through the deodorizing filter 5 as shown by the dashed line and the solid arrow, undergoing a decomposition reaction to be described later, and diffuses to the outside as oxygen. As this diffusion occurs, the external malodorous air G passes through the deodorizing filter 5 as shown by the two-dot chain arrow while adsorbing and concentrating a part of the malodorous components, is taken into the space 7, and is oxidized and decomposed as described later. It becomes odorless and diffuses outside. Since diffusion and uptake are performed slowly in this way, the sealed space around the deodorizer 9 is circulated as a whole over time, and deodorization progresses.

Regarding the decomposition reaction of ozone, the ozone undergoes the following nine steps, and by the time it reaches the surface of the deodorizing filter 5, it is decomposed into oxygen and becomes harmless. That is, (1) self-decomposition reaction in the space 7 (203→802), (Ozone adsorbed and concentrated in the Ill deodorizing filter 5 is decomposed by the ozone decomposition catalyst (0, +M→O, +O+M, M is the catalyst) Note that ozone in the space 7 is relatively stable, with a half-life of several hours to more than ten hours.

Most of it is decomposed in the process (11). The amount of ozone generated depends on factors such as the applied voltage and the volume of the space.

Also, the amount of ozone decomposed depends on the thickness of the deodorizing filter 5.

Since it depends on the amount of catalyst supported, if these are adjusted appropriately, ozone will not leak out of the deodorizer 9 and the space 7
A highly concentrated ozone atmosphere can be created inside.

The oxidative decomposition and deodorization of the malodorous components is carried out through the following first-order process. That is, (1) gas phase oxidative decomposition with ozone in the space 7; [11] ozone or catalyst after being adsorbed by the deodorizing filter 5? This leads to oxidative decomposition, (Ill) Active species generated from ozone adsorbed to the deodorizing body or ozone decomposed after adsorption (zero oxygen during the nascent stage)
The decomposition is done by t011, (till
Deodorization progresses through the process of That is, the malodorous components partially adsorbed and concentrated by the deodorizing filter 5 are decomposed through the reaction process (11). In addition, when the oxidative decomposition and deodorization progresses and the malodorous components in the malodorous air G are equal to zero, the ozone generated from the electric field device 1O is decomposed by repeating the same reaction as the ozone decomposition reaction. It becomes harmless and spreads outside.

In Fig. 3.7, a simple deodorizer 9 using an ultraviolet lamp of the present invention includes an ozone generating ultraviolet lamp 11 and an AC power source 14.
When a voltage from m is applied through the ballast plane, the wavelength 20
Light with a wavelength of 0 nm or less, mainly light with a wavelength of 185 nm, is strongly emitted, and the oxygen in the space 7 absorbs the light with this wavelength, and ozone is generated according to the linear equation.

In the figure, 17 is an electric wire.

(h+hν(200nm or less)-, O+00+02+M
-C) 3+MCM is a third object such as O, N, etc.) The generated ozone is generated by the heat energy of the ultraviolet lamp H. While undergoing the decomposition reaction described below, it passes through as shown by the dashed-dotted line and the solid arrow, becoming oxygen and diffusing to the outside. This diffusion - the foul-smelling air outside
passes through the deodorizing filter 5 as shown by the two-dot chain arrow while adsorbing and concentrating some of the malodorous components, is taken into the space 7, and is oxidized and decomposed to be odorless and diffused to the outside as described later. . Considering that the diffusion and uptake are performed slowly in this way, the sealed space around the deodorizer 9 is
As a whole, it circulates over time and deodorization progresses.

When the ozone decomposition reaction occurs, the ozone goes through the following 9 steps, and by the time it reaches the surface of the deodorizing filter 5, the ozone is decomposed by oxygen and becomes harmless. That is, (1) self-decomposition reaction (20s = 80g) in the space 7, the ozone adsorbed and concentrated on the til + deodorizing filter 5 is decomposed by the ozone decomposition catalyst l (Os + A → Oj + O + A, A is catalytic [-
)do. In addition, ozone in the air is relatively stable with a half-life of several hours to over ten hours, and most of it is (II).
decomposes in the process of The amount of ozone generated is related to the energy distribution and illuminance of the ultraviolet lamp, and the amount of ozone decomposed depends on the thickness of the deodorizing filter 5 and the amount of catalyst supported, so if these are adjusted appropriately, ozone can be reduced. There is no leakage outside the deodorizer.

A highly concentrated ozone atmosphere can be created within the space 7.

The oxidative decomposition and deodorization of the malodorous components is carried out through the following process. That is, (1) gas-phase oxidative decomposition with ozone in the space 7, (oxidative decomposition with ozone or a catalyst after being adsorbed by the I11 deodorizing filter 5,
(Active species generated from ozone adsorbed on the till deodorizing filter 5 or ozone decomposed after adsorption (no oxygen in the nascent stage) are mainly decomposed by (II),
(Deodorization progresses through the process 1+11. That is, the malodorous components partially adsorbed and concentrated by the deodorizing filter 51C are decomposed through the reaction process (11).

When the oxidative decomposition and deodorization progress and the malodorous components in the malodorous air G are equal to zero, the ozone generated by the ultraviolet lamp 11 is decomposed by repeating the same number of reactions as the ozone decomposition reaction. It becomes harmless and spreads outside.

The deodorizing effect of the deodorizer (shown in Figure 6) using the electric field device of this invention will be explained with reference to Figure 8.9.
= 10 m, and a deodorizer 9 is installed with a facing distance d = 5 m between the electric field device (■) and the deodorizing filter 5.

The electric field device U of the deodorizer 9 is connected to a transformer via a line 19, and the electric field device U is connected to a transformer via a line 19. The power supplies η are connected in this order. The illusion is the pipe, 24 is the dryer, 25 is the blower, 26 is the exhaust hole,
27 is a measurement hole, and 28 is a stirring blade. After the humidity in the box m is made constant using the dryer 24, highly concentrated hydrogen sulfide is sealed in the box m using a syringe 291C.

Next, the interior is stirred by a single blade passage until the inside becomes dense (3D~
40 ppm). When a voltage of V is applied to the electric field device 9#8.5, the removal rate of hydrogen sulfide increases by t with the passage of time, as shown by curve 2 in FIG. Curve 1 is the case when no electric field device 9 is applied, other conditions are the same as above, and curve 1 is when no catalyst is added to the carrier 8, and no application is applied to the electric field device 9, other conditions are the same as above. This is the result.

Curve 1 shows that hydrogen sulfide is adsorbed and concentrated on the granular carrier 8, and curve 9 shows that hydrogen sulfide and the catalyst react and decompose in addition to the adsorption and concentration, so that the removal rate of hydrogen sulfide increases. This is expected to increase. When an electric field is applied thereto to generate ozone, hydrogen sulfide is decomposed by ozone and active species as described above, and the removal rate of hydrogen sulfide is further increased as shown by curve I.

Next, the deodorizing effect of the deodorizer (shown in Figure 7) using an ultraviolet lamp of the present invention will be explained with reference to Figures 8, 10, and 11. A deodorizer 9 is installed with a thickness of t-10 mm and a facing distance between the ultraviolet lamp 11 and the deodorizing filter 5 of d = 5 wa.

Unlike the above, the deodorizer 9 is connected to a power source via a wire stabilizer (not shown). After keeping the humidity in the box m constant by drying, high-concentration hydrogen sulfide is sealed in the box m using a syringe 29 and stirred by one and then two blades to maintain a uniform concentration (30 to 40 ppm) inside. tRub. Then, changes over time in the concentration of hydrogen sulfide inside were measured using a hydrogen sulfide gas stick.

The results are shown in Figure 10. Curve 1 (■) is when the ultraviolet lamp 11 is turned on (Experiment 1); curve V (9) is when the lamp U is turned off (Experiment I); curve (1) is deodorization. filter 5
Instead, a filter containing the carrier 8 inside the box 2 was used and the lamp 11 was turned off (experimental example), and the other conditions were the same as in the above two cases.

In the example of experiment (2), decomposition of hydrogen sulfide by ozone and catalyst cannot be expected, but the main cause of the decrease in hydrogen sulfide concentration is considered to be adsorption/concentration by the granular carrier 8 and adsorption to the wall surface.

In the example of Experiment I, the concentration of hydrogen sulfide is greatly reduced compared to Experiment I, due to the addition of the reaction with the hydrogen sulfide 2 catalyst in addition to the adsorption and concentration. When the lamp U is turned on to generate ozone, the concentration of hydrogen sulfide further decreases as shown by curve (2), which indicates that ozone is effective in removing hydrogen sulfide.

As is clear from the following experiment and FIG.
Ozone has the effect of reactivating the deteriorating catalyst and increasing the deodorizing effectiveness. In other words, curve 1 indicates that 60% of hydrogen sulfide is present in a high concentration hydrogen sulfide (0.1%) atmosphere in a container in which a deodorizer 9 is separately prepared.
After leaving it for a minute, it was taken out and placed in a box m under the same conditions as in the previous experiment, and the lamp 11 was turned off.
Experiment ■).

Curve (2) indicates that the deodorizer 9 immediately after the experiment (2) was left in an ozone atmosphere in a separately prepared container for (9) minutes, then taken out and placed in a box (m) under the same conditions as in the experiment, and the same procedure was carried out. Curve 1 shows the case where the lamp 11 was turned off (experiment V), and the curve (2) shows the case where the lamp U of the deodorizer 9 was turned on after the experiment V was completed to generate ozone (experiment ■). The hydrogen sulfide removal performance of the curve (2) is significantly lower than that of the curve (V) under this strike condition. This can be assumed to be due to the deterioration of the catalyst's ability as the catalyst reacts with hydrogen sulfide to produce sulfide. However, the deodorizer 9 with this deteriorated catalyst shows a curve of 1 after being left in an ozone atmosphere. As shown in the figure, the hydrogen sulfide removal performance has recovered, and in the experiment (2) in which ozone was generated, the performance was even better. In this way, ozone reactivates the catalyst degraded by hydrogen sulfide (
It can be seen that the decomposition of generated sulfides) improves the deodorizing effect.

The deodorizer 9 of the present invention is safe as no ozone leaks out of the deodorizer 9, and this can be demonstrated by the following experiment and table. That is, the deodorizer 9 using the electric field device 10 is installed in the closed box used in the experiment described above. In this experiment, the concentration of ozone (p
pm) was measured.

During the measurement, an ozone gas detection tube was used to measure from the measurement hole η. The following table shows the results.

Table 1 (Thickness of deodorizing filter t = 10 m) Table 2 (Thickness of deodorizing filter t - 20 m) The values in the table are the ozone concentration in the box rail after 60 minutes of application of Wl pressure (ppm)
is the measured value. That is, in order to prevent the outflow of ozone, it can be determined by the appropriate values in Table 1. In addition,
A catalyst-untreated carrier 8 is placed inside the box body 2 instead of a deodorizing filter.
A deodorizer is constructed by using a filter (thickness 10 -) with a built-in filter and an electric field device with a facing distance of 5 -, and applying a voltage of 2. The ozone concentration after 1 minute when I KV was applied was 8.2 ppm.

Regarding the safety of deodorizer 9 that uses ultraviolet light.

This can be demonstrated by the following experiments and tables. That is, the deodorizer 9 used in the above experiment was installed in the closed box. In this experiment, the thickness of the deodorizing filter 5 (t = 10 mm) was kept constant, and the opposing distance (di) between the lamp U and the deodorizing filter 6 was varied (d = 5 m, d = 13 m). After turning on U, the concentration of ozone flowing out of the deodorizer 9 was measured over time.In the measurement, an ozone gas detection tube was used to measure from the measurement hole η.The following table shows the results. For reference, Table 3 shows the measured values when a filter (thickness: 10 cm) containing a catalyst-untreated carrier 8 in the box body 2 was used in place of the deodorizing filter.

Table 1 (Opposing distance d = 5 wm) Table 2 (Opposing distance d = 13 wm) Table 3 (Opposing distance d = 51) As is clear from the numbers in the table, ozone is completely absorbed outside (
There was no leakage, and the safety of this deodorizer 9 can be confirmed.

In Table 8, ozone with a concentration of ppm leaks out, but this value deteriorates over time and becomes harmful.

Effects of the Invention As described above, the present invention comprises an ozone generator and a deodorizing filter containing deodorizing particles in a breathable box, or the ozone generator comprising the filter and a non-ventilating body. It consists of a deodorizer body with a space, and an ozone generator is installed inside the space of the main body to generate ozone.This type of deodorizer can be easily made smaller and simpler, and has a wide range of applications. can be expanded, and its effects are great when applied to general households.
