Abstract

The present invention provides a filter device including a deodorization filter and means for maintaining the performance of a deodorization filter having a high deodorization velocity, in which re-emission of removed odor molecules is suppressed, which can be used stably for a long period of time without any regeneration operation .

The deodorization filter is composed of an adsorbent that adsorbs odor molecules and a transition metal chelate compound that is used as a catalyst for odor molecules to cause an oxidation reaction. Rapid adsorption by adsorbents is combined with decomposition of odor separated from adsorbents by using transition metal chelate compounds to maintain long - term performance. As an example of the filter, the composite deodorization filter 10 is manufactured by wrapping the activated carbon filter 2 with a breathable bag 1 made of a nonwoven fabric carrying a transition metal chelate compound, as shown in the figure. Furthermore, a breathable heating means is provided to promote the decomposition of odor molecules. A water supply means for supplying water to the multiple deodorization filter is added to prevent performance deterioration in a low humidity environment.

For example, by removing the oxygen dissolved in the alkaline aqueous solution in which the metal phthalocyanine complex is dissolved by the bubbles of the inert gas, the occurrence of the dimerization of the complex molecule which otherwise may deteriorate the deodorization performance is inhibited, .

Description

Complex deodorization filter, complex deodorization filter device comprising same and method for manufacturing deodorization filter

TECHNICAL FIELD The present invention relates to a deodorizing filter for removing odors in the air, which is mainly used in electric equipment including an air conditioner.

Recently, as the quality of living environment has increased, the demand for improved comfort of living environment has been increasing. The smell persists in the modern house where the air is cramped. There is an increasing demand for the smell of cigarettes, sweat, and odors from the body of a baby or pet. In the end, it has been proposed to incorporate a deodorizing or deodorizing filter in an air conditioner including an air purifier. In this approach for deodorization, activated carbon, photo-catalyzed oxidation or ozone oxidation reactions are commonly used.

Activated carbon adsorbs odor molecules and removes odors from the atmosphere. However, since the adsorption performance of the filter is limited, the adsorption function is temporary, so that the odor molecules adsorbed on the activated carbon are discharged and removed from the equilibrium.

In order to overcome such a problem, there has been proposed a method of deodorizing by catalytic metal oxidation using platinum, nickel or the like while regenerating activated carbon by heat treatment (for example, Japanese Patent Application Laid-Open Nos. 63-240923 and 3- 224619). However, in order to carry out the metal catalytic oxidation, it is always necessary to continuously heat the activated carbon to about 300 to 400 캜. Activated carbon at high temperature is at risk of ignition. When the deodorizing filter is used in household electrical appliances other than cooking appliances and heating appliances, power consumption must be increased or the appliance must be heat-resistant. Since the heating temperature is high, the separation rate is higher than the catalyst speed, and the odor can not be sufficiently removed. Odor molecules and molecules released by the catalyst can react with each other at heating temperatures to release toxic components and new odors.

In the deodorization method using the photo-catalytic oxidation reaction, the deodorization speed is slow and it is necessary to provide an excitation light source. The use of lamps causes problems of high cost and high power consumption.

In the ozone oxidation reaction, an apparatus for decomposing an excessive amount of ozone is indispensable. This results in problems such as high cost, high power consumption, instability due to the fact that ozone itself is toxic to the human body.

An oxidation catalyst method using a transition metal chelate compound such as an iron phthalocyanine complex compound as a method for solving the problem in the above-described method is attracting attention. This method is described in literature (e.g., Hirfusa Shirai, Kagagu to Kogyo, p. 27, Oct, 1990, Naoki Toshima, Kogyo Zairyo, p. . A deodorant utilizing the oxidation and reduction ability of the metal phthalocyanine is disclosed in Japanese Patent Laid-Open No. 63-977555. Because many odor molecules have a fluid hydrogen atom, deodorization is possible by oxidation by dehydrogenation, that is, by dimerization which makes odor molecules water soluble and non-volatile.

Such a deodorization method can be described in the embodiment in which the in vivo enzyme reacts with odor molecules. The catalase enzyme that performs this reaction contains hematoporphyrin bound to the apoprotein. The histidine imidazole nitrogen atom of the iron atom and protein in the trivalent spin transfer state is coordinated at the fifth coordination position. Carboxyphthalocyanine iron complexes having catalytic activity similar to those of catalase enzymes such as octacarboxyphthalocyanine iron complexes will decompose in accordance with catalase-like reaction mechanisms and will have catalytic activity six times higher than hemin. In the mercaptan example, the oxidation is represented by the following chemical reaction formula.

2-R-SH + 2OH ^- ? 2R-S ^- + 2H ₂ O (1)

2 - RS ^- + 2H ₂ O + O _{2 -} > RSSR + H ₂ O ₂ + 2OH ^- (2)

In the formula, R represents CH ₃ and C ₂ H ₅ .

The chelate anion formed by the reaction formula (1) is coordinated with a metal phthalocyanine to become an active species which is a quaternary complex. The chelate anion coordinated to this active species is dehydrated by disulfide.

However, the transition metal chelate compound has a problem that the deodorization rate is slower than that of activated carbon and its deodorizing effect is remarkably low in an environment such as an air conditioner in which air flows.

The present invention was made under the above-mentioned circumstances. Disclosed is a deodorizing filter which has a high deodorizing speed and a high deodorizing effect even in an air flow environment, can suppress the re-emission of removed odor molecules, requires no regeneration operation and can be stably used for a long period of time, There is provided a deodorizing filter device including means for maintaining and improving the performance of a deodorizing filter.

PREFERRED EMBODIMENTS OF THE INVENTION [

The odor molecules are primarily adsorbed by the odorant molecule adsorbent composed mainly of activated carbon. Therefore, even in the case of an air flow environment, deodorization proceeds effectively. Leakage of odor due to separation from the adsorbent can be blocked by decomposing the odor molecules separated from the activated carbon by the corosion catalytic reaction of the transition metal chelate compound adjacent to the adsorbent. The separated odor molecules are removed by the decomposition reaction, and the chemical equilibrium changes between the adsorption and separation of the odor molecules in the activated carbon, and the separation and binding proceeds. Therefore, the adsorption force of activated carbon will not be saturated. Therefore, it is possible to provide a deodorizing filter in which the adsorption and decomposition of odor molecules proceeds by the two substances, and the deodorization speed is fast and the deodorizing effect is effective even in an air flow environment applicable to an air conditioner or the like.

The installation of the heating means coupled to the odorant molecular sorbent to prevent the adsorption rate from decreasing the adsorption rate due to the thermodynamic dependence on the separation and decomposition rate of odor molecules promotes the separation reaction of odor molecules. The separated odor molecules are dispersed in a filter composed of a transition metal chelate compound and rapidly decomposed. Therefore, the adsorption rate reaches equilibrium and is not slowed down. Recovery of the odorant molecular sorbent is not necessary since the separation reaction is actively promoted. Promotion of separation by heating can simultaneously or intermittently proceed with the deodorizing operation. Alternatively, it may proceed after termination of the deodorization operation. Therefore, the adsorption and decomposition of the odor molecules are promoted by both the filter means and the heating means, so that the deodorizing effect can be effectively applied even in an air flow environment, which can be used for air conditioners, A deodorization filter can be provided.

The humidity of the room is lowered and moisture is removed from the deodorizing filter to dry the filter to prevent the deodorizing effect of the transition metal chelating material from deteriorating, so that the deodorizing filter is constantly provided with an appropriate amount of water or water for enhancing the deodorizing effect. The reaction path for injecting water (preferably a deodorizing liquid) into the deodorization filter is to provide a constant water content of the filter. The reaction path is provided to thermally cool the filter to condense water in the air to supply water to the filter.

An embodiment of a composite deodorization filter comprising an odorant molecule sorbent material consists essentially of a transition metal chelate compound and activated carbon that perform a catalytic reaction to odor molecules. The odorant molecular sorbent is selected from the group of alkali-added carbon, acid-added carbon, activated carbon, zeolite, cepiolite, flypontite (porous aluminosilicate) porous silicate metal, One or more, for example in the form of a filter. The transition metal chelate compound may preferably be a transition metal porphyrin, more preferably a metal phthalocyanine.

The filter may have a breathable filter structure as follows.

(1) A structure in which an activated carbon filter is wrapped with a bag-like nonwoven fabric carrying octacarboxyphthalocyanine iron (Figs. 1A and 1B).

(2) a structure in which an activated carbon filter is disposed between two sheets of airtight non-woven fabric carrying octacarboxyphthalocyanine iron (Figs. 2A and 2B).

(3) a breathable structure in which a fibrous transition metal chelate compound and fibrous activated carbon are interwoven with each other, or a fibrous activated carbon in which a metal chelate compound is embedded or intercalated into a breathable substrate (FIG.

(4) A structure in which granular activated carbon carrying octacarboxyphthalocyanine iron is placed in a casing (Figs. 4a and 4b).

Hereinafter, 1a and 1b will be described.

Octacarboxyphthalocyanine iron was dissolved in potassium hydroxide to prepare 1% octacarboxyphthalocyanine iron solution. The bag-type breathable nonwoven fabric was immersed in the solution. Octacarboxyphthalocyanine iron was supported on the fabric by neutralization under a hydrochloric atmosphere. The activated carbon filter 2 used as the odor molecule adsorbent is inserted into the airtight bag 1 made of a nonwoven fabric carrying octacarboxyphthalocyanine iron as shown in Figs. 1A and 1B, whereby the activated carbon filter 2 is treated with octacarboxyphthalocyanine iron A composite deodorizing filter 10 wrapped with a filter (breathable bag) 1 was produced.

The produced composite deodorizing filter 10 was disposed between the dust collecting filter 9 and the heat exchanger 11 of the indoor equipment of the domestic air conditioner as shown in Figs. 14.a and 14b. An air conditioner equipped with a filter was installed in the evaluation box (1 cubic meter). The air in the evaluation box was adjusted to a general home atmosphere of a temperature of 25 ° C and a humidity of 50%, and hydrogen sulfide gas was introduced therein. The hydrogen sulfide was sampled before and during operation of the air conditioner and its concentration was measured by gas chromatography with a detection tube and a flame photometric detector. Similar measurements were made on a single activated carbon that was not wrapped with a control, octacarboxyphthalocyanine iron filter.

In the first measurement, both filters show deodorization effect over time, but there is no practical difference. After 90 minutes, the composite deodorizing filter containing only activated carbon showed a slightly higher deodorizing effect. However, the hydrogen sulfide gas was again received and manipulated without changing the filter, and a similar evaluation was repeated for 2 hours. The third and last measurement is the composite deodorization filter of the present invention. As shown in Fig. 6, clearly shows a larger deodorizing effect. Since the hydrogen sulfide adsorbed by the activated carbon is saturated, the filter containing only the activated carbon loses its deodorizing effect. On the other hand, when the hydrogen sulfide adsorbed on the activated carbon is separated from the activated carbon in the composite deodorization filter, .

Hereinafter, 2a and Fig. 2b will be described.

Hereinafter, 3 will be described. As shown in Fig. 3, a composite deodorizing filter 10 in which fibers carrying octacarboxyphthalocyanine iron and activated carbon fibers were interwoven was prepared.

After installing the deodorizing filter on the air conditioner, Similar to the embodiment shown in Figs. 1a, 1b, 2a and 2b, 14a and 14b. The deodorizing effect was measured under conditions of an installation temperature of 25 캜 and a humidity of 50%. As a result, 1a and 1b. The deodorizing filter not only exhibited deodorizing effect but also continued its deodorizing effect even if the operation was repeated.

Hereinafter, 4a and 4b will be described.

After the activated carbon granules were immersed in 1% of octacarboxyphthalocyanine iron-potassium hydroxide solution, they were taken out and neutralized in a hydrochloric acid atmosphere to carry octacarboxyphthalocyanine iron on the activated carbon granules. Degree. As shown in Fig. 4a, carbon granules were placed in the case 4 made of this breathable porous paper.

The case 4 was disposed between the sheets 6 of the breathable porous paper to prepare the composite deodorizing filter 10. [ As shown in Fig. 4a, it is possible to use a pair of filters with the same sides facing each other. Alternatively, as shown in Fig. 4 (b), two sheets of air-permeable porous paper were stacked to make a bag to which octaftalothiocyanine iron supported on activated carbon granules was added. The edges of the porous paper were decorated and punched to unevenly distribute the granules. It is possible to use a plurality of boxes 5 composed of two breathable porous paper sheets.

The produced composite deodorizing filter 10 was disposed between the dust collecting filter 9 and the heat exchanger 11 of the indoor equipment of the domestic air conditioner as shown in Figs. 14.a and 14b. The air conditioner equipped with this filter was installed in the evaluation box (1 cubic meter). The air in the evaluation box was adjusted to a general home atmosphere of a temperature of 25 ° C and a humidity of 50%, and hydrogen sulfide was introduced therein. The hydrogen sulfide was sampled before and during operation of the air conditioner and its concentration was measured by gas chromatography with a detection tube and a flame photometric detector (FPD).

As a result, the smell of hydrogen sulfide was removed. The time for reducing the relative odor is also shown in Fig. 1a and 1b. It took 2 hours for the relative concentration to be less than 1%. However, too. The deodorizing effect was not lost even if this operation was repeated as in the case of the embodiment of Figs. 1a and 1b.

(6) Structure for absorbing odor molecule powder or granular material (mixture of odor molecule adsorbing material and transition metal chelate compound, odor molecule adsorbing material (not shown) coated with transition metal chelate compound).

Hereinafter, 7a and 7b will be described.

Octacarboxyphthalocyanine iron was dissolved in potassium hydroxide corresponding to the carboxyl group of octacarboxyphthalocyanine iron to prepare a 1% solution of octacarboxyphthalocyanine iron. The bag-like breathable nonwoven fabric was immersed in the solution, then lifted, and then neutralized by immersion in dilute hydrochloric acid solution. And dried with air to carry octacarboxyphthalocyanine iron to the fabric.

As shown in FIGS. 7A and 7B, by inserting the activated carbon 2 of the odor molecule adsorbing material and the heating plate 36 in the mesh form into the breathable bag 1 carrying octaftalothiocyanin iron, the heating means and the odor absorbing substance Was wrapped with a bag of a transition metal chelate compound to prepare a composite deodorizing filter (10).

The produced composite deodorizing filter 10 was disposed between the dust filter 9 and the heat exchanger 11 of the indoor equipment of the domestic air conditioner as shown in Figs. 14.a and 14b. An air conditioner equipped with a filter was installed in the evaluation box (1 cubic meter). The air in the evaluation box was adjusted to a general home atmosphere of a temperature of 25 ° C and a humidity of 50%, and hydrogen sulfide was introduced therein. The hydrogen sulfide was sampled before and during operation of the air conditioner and its concentration was measured by gas chromatography with a detection tube and a flame photometric detector. When using detection tubes or gas chromatography, they were measured at initial concentrations of 80 ppm and 100 ppb, respectively. Similar measurements were also made on activated carbon without octacarboxyphthalocyanine iron for comparison, filter type. Measurement results also. As shown in Fig. 12, both filters exhibited deodorizing ability and showed a decrease in the residual odor with the passage of time.

Measurements were made for odors other than hydrogen sulfide. Similar results were obtained. (Relative concentration) of each odor after 120 minutes of filtration. Respectively.

Degree. The composite deodorization filters shown in Figs. 7a and 7b were used. Degree. An activated carbon filter without the octacarboxyphthalocyanine iron bag of the composite deodorization filter shown in 7a and 7b was used.

The measurement was performed using a detection tube. Initial concentrations of odor such as hydrogen sulfide, ammonia, trimethylamine and methylmercaptan were 80 ppm, 400 ppm, 100 ppm and 300 ppm, respectively.

After measuring the residual odor ratio after 120 minutes, the operation of the air conditioner was stopped and energy was applied to the heating plate 36 of the composite deodorization filter for 300 minutes. Next, without replacing the air purifier, the sulfurized hot gas was introduced again, and the concentration of hydrogen sulfide in the evaluation box was measured by operating the air conditioner. After such a process involving air-conditioner operation for 2 hours, the filter was heated for 30 minutes and hydrogen sulfide was again introduced to repeat the measurement of the deodorizing ability over time. Repeated measurements were made by using a composite deodorization filter with the heating means of the present embodiment, a composite deodorization filter without a heating means wrapping odor molecule adsorbing material as a bag of transition metal chelate compound, and a single activated carbon filter for comparison. The results are shown in Fig. As shown in FIG. 13, the composite deodorizing filter of the present invention with heating means has shown that even if the air conditioner is repeatedly operated, it has higher deodorizing ability than the filter that does not have the heating means. In particular, prior art filters containing only activated carbon showed a significant reduction in deodorizing ability. This is because the hydrogen sulfide adsorbed by the activated carbon is saturated and the deodorizing ability of the filter is lost. On the other hand, the hydrogen sulfide adsorbed by activated carbon was deodorized by the oxidation reaction with octacarboxyphthalic iron when it was separated in the composite deodorization filter. Particularly, the composite deodorizing filter including the heating means promotes the separation of the odor component, so that the adsorption ability of the activated carbon filter is maintained.

Similar measurements were made during the last 30 minutes in 120 minutes, i.e., 90 minutes after operating the air conditioner. The concentration of hydrogen sulfide after the end of 120 minutes of measurement was increased by 5% over the initial heating. The deodorizing ability remained constant even after repeated introduction of hydrogen sulfide.

In this way, heating was intermittently performed even during or after the air conditioner operation.

Degree. Similar results were obtained with the filter structures shown in Figs. 8a, 8b, 9a and 9b. The heating plate 36 is also shown. 8a and 8b, the amount of heating from the heating plate 36 is lowered because it is in direct contact with the air-permeable bag 1 carrying octacarboxyphthalocyanine iron. Therefore, the deodorizing ability after the odor inflow is repeated several times. 7a, 7b, 9a and 9b. This lowering of the deodorizing ability can be prevented by adjusting the heating time and heating amount when operating the air conditioner practically.

Hereinafter, 10a, 10b, 11a and 11b will be described.

Degree. As shown in Figs. 10a and 10b, a mesh-type heating plate 36 is disposed between two activated carbon filters 2, and then placed between two sheets of a breathable nonwoven fabric 1 carrying iron-octacarboxyphthalic iron Respectively. Thus, a composite deodorizing filter 10 having air permeability was produced.

The produced composite deodorizing filter 10 may be attached to an air conditioner and then installed in an evaluation box. The deodorizing effect was measured similarly to the example shown in 7a and 7b. The measurement results are not greatly different from the results of the embodiments of Figs. 7a and 7b. The deodorizing filter 10 not only exhibits a deodorizing effect but also has a deodorizing effect even when the operation is repeated.

Degree. Similar results were obtained when a filter having the structure shown in Figs. 11a and 11b was used.

Hereinafter, embodiments in which a fibrous adsorbent and a transition metal chelate compound are incorporated into a heating means will be described.

A ventilated composite deodorization filter 10 (similar to the above-described embodiment shown in Fig. 3) in which octacarboxyphthalonized iron-carrying breathable fibers and fibrous activated carbon were incorporated into a mesh-type heating plate was prepared.

The produced composite deodorizing filter 10 may be attached to an air conditioner and then installed in an evaluation box. The deodorizing effect was measured similarly to the implementation shown in 7a and 7b. The measurement results are shown in Fig. 7a and 7b. ≪ / RTI > The deodorizing filter not only exhibited the deodorizing effect but also continued its deodorizing effect even when the operation was repeated.

Hereinafter, an embodiment in which a net-like heating plate is made of a breathable porous paper using the case in the embodiment shown in Figs. 4A and 4B will be described.

Octacarboxyphthalocyanine iron was dissolved in potassium hydroxide corresponding to the carboxyl group of octacarboxyphthalonine iron to carry 1% of octacarboxyphthalocyanine iron. As shown in Figs. 4A and 4B, the activated carbon granules were placed in a case 4 made of a breathable porous paper. The composite deodorizing filter 10 was manufactured by using the case 4 in the mesh-type heating plate. (This was described as the breathable porous paper 6 in the above embodiment, in which no heating means was used.) Two types The composite deodorization filter can be used so that the same surface is in contact with each other. Alternatively, 4b, a heating plate could be inserted into the bag of breathable porous paper, and granular activated carbon carrying octacarboxyphthalocyanine iron was added to the bag. It is also possible to drill holes in the bag to evenly distribute the granules. Accordingly, the composite deodorization filter 10 can be manufactured.

As shown in Figs. 14.a and 14b, the produced composite deodorizing filter 10 was disposed between the dust filter 9 and the heat exchanger 11 of the domestic appliance of the domestic air conditioner. The air conditioner with this filter was attached to the evaluation box (1 cubic meter). The air in the evaluation box was adjusted to a typical domestic atmosphere of 25 ° C and 60% humidity and hydrogen sulfide was placed therein. The hydrogen sulfide was sampled before and during operation of the air conditioner and its concentration was measured by gas chromatography with a detection tube and a flame photometric detector (FPD). A single activated carbon filter not containing octacarboxyphthalocyanine iron was also subjected to similar measurements.

Both filters were dehydrated with hydrogen sulfide. Due to the pressure loss, it took 120 minutes for the relative concentration to reach 3%. However, the composite deodorization filter according to the present embodiment is also a deodorizing filter. As in the examples of 7a and 7b, the deodorizing ability was not lost even when the operation was repeated.

As an example of a device using a composite deodorization filter with heating means, the composite deodorization filter 10 of the embodiment shown in Figs. 15a and 15b, an air purifier disposed between the ventilator 15 and the air outlet 18 was manufactured. The composite deodorization filter 10 may be disposed between the dust filter 16 and the ventilator 17. The deodorizing effect of the air purifier provided with the composite deodorizing filter 10 lasted for about 3 months.

The odor generated in the lacquer was deodorized when it was discharged through the exhaust opening 25 through the exhaust guide 26. Deodorizing effect persisted after 1 month of filter use. When only the dried food is heated in the range, the deodorizing effect is lowered because the space of the microwave range is present in a very dry state.

In the following, an embodiment of a composite deodorization filter device comprising means for providing an appropriate amount of water or moisture to the device is described.

A composite deodorization filter was prepared by a method similar to that described above. The water injection nozzle 33 is attached to the water storage container 34 to spray water onto the surface of the composite deodorization filter 10 and applied to the water injection when the moisture content in the composite deodorization filter 10 is reduced. Degree. 19, the manufactured composite deodorizing filter device was attached to the dust filter 30 of the indoor air conditioner of the domestic air conditioner.

To measure the deodorizing effect, the air conditioner equipped with the composite deodorizing filter device was installed in a deodorization evaluation box (1 cubic meter). The temperature and humidity in the evaluation box were adjusted to 25 캜 and 20% or 50%, respectively. A hydrogen sulfide gas was introduced into the box, and sampling was performed before and after the operation of the air conditioner. The concentration of hydrogen sulfide gas was measured with a detection tube. The initial concentration of hydrogen sulfide gas was 60 ppm.

The result of the measurement shows that when the humidity was 50%, the hydrogen sulfide was totally deodorized by the composite deodorization filter after 30 minutes. When the humidity was 20%, no hydrogen sulfide was detected by the detection tube. However, when the humidity was 20%, the concentration of hydrogen sulfide after 5 minutes was 30 ppm. After 90 minutes, the hydrogen sulfide gas could be completely deodorized. The moisture content in the composite deodorization filter was increased by spraying water into the composite deodorization filter 10 before introduction of the hydrogen sulfide gas when the humidity was 20%. As a result, hydrogen sulfide was totally deodorized after 30 minutes, just like when the humidity was 50%.

Hereinafter, another embodiment of the multiple deodorization filter device will be described.

Hereinafter, a deodorizing filter manufacturing method having a metal honeycomb structure will be described.

1% aqueous solution of potassium hydroxide containing octacarboxyphthalocyanine iron was prepared. A metal plate with a honeycomb structure with a small pressure loss (the surface of which was coated with zeolite powder in combination with a binder) was immersed in an aqueous solution, then lifted and immersed in a dilute hydrochloric acid solution for neutralization. Subsequently, it was thoroughly washed, and octacarboxyphthalocyanine iron was supported on the surface of the metal filter.

For the cooling of the composite deodorization filter 10, a composite deodorization filter device with a Peltier effect member 35 was manufactured. Water can be supplied to the composite deodorizing filter 10 by causing the temperature on the Peltier member 35 to be lowered by thermionic coding so that moisture in the air is condensed.

Degree. 20, the produced composite deodorizing filter device was attached to the dust collecting filter 30 of the indoor equipment of the domestic air conditioner and installed in an air conditioner deodorization evaluation box (1 cubic meter).

To measure the deodorizing effect, the air conditioner equipped with the composite deodorizing filter device was installed in a deodorization evaluation box (1 cubic meter). The temperature and humidity in the evaluation box were adjusted to 25 캜 and 20% or 50%, respectively. Hydrogen sulfide gas was introduced into the box and sampled before and after the operation of the air conditioner. The concentration of hydrogen sulfide gas was measured with a detection tube. The initial concentration of hydrogen sulfide gas was 70 ppm.

The result of the measurement shows that when the humidity was 50%, the hydrogen sulfide was totally deodorized by the composite deodorization filter after 30 minutes, and no hydrogen sulfide was detected in the detection tube. However, when the humidity was 20%, the concentration of hydrogen sulfide after 30 minutes was 10 ppm, and hydrogen sulfide was completely deodorized after 100 minutes. The moisture content in the composite deodorization filter was increased by spraying water into the composite deodorization filter 10 before introducing the hydrogen sulfide gas when the humidity was 20%. As a result, hydrogen sulfide was completely deodorized after 30 minutes as the moisture content in the filter increased.

In the deodorization filter comprising the metal phthalocyanine complex compound mixed with the deodorizing molecular adsorbent such as activated carbon or zeolite, since the deodorization is carried out by adsorption of odor molecules to the metal phthalocyanine complex compound, the metal phthalocyanine is adsorbed to the filter support It is necessary to combine them. Therefore, the metal phthalocyanine chemically binds to the inorganic substance or the polymer compound to prevent the dimer from being formed.

The molecular structure of the octacarbonate-iron phthalocyanine having eight carboxyl groups is also shown. Lt; / RTI > However, it has been found that metal phthalocyanine molecules generally form dimers in alkaline aqueous solutions over time.

Such a metal phthalocyanine is itself a double-phase linear, and ultimately, To form a metal phthalocyanine dimer and a metal phthalocyanine-mu-oximeter as shown in Fig. 22a. Therefore, the center metal M can not accept electrons of other substances, and the catalytic activity will be lowered.

An embodiment of a deodorization filter manufacturing method will be described below. In this case, no metal phthalocyanine dimer will be formed in the alkaline aqueous solution in which the metal phthalocyanine is dissolved.

In practice, by removing the dissolved oxygen in the aqueous solution, From dimer to dimer can be suppressed. Furthermore, it has been found that addition of a bubbling or sodium sulphite anhydride salt using an inert gas is effective for removing oxygen dissolved in alkaline aqueous solution.

In order to solve the above-described problems, the present invention or a method of manufacturing a deodorizing filter includes the steps of providing an alkaline aqueous solution in which a polycarboxylic acid-metal-phthalocyanine is dissolved, removing oxygen dissolved in an alkaline aqueous solution, And the polycarboxylic acid-metal-phthalocyanine is supported on the filter carrier, the polycarboxylic acid-metal-phthalocyanine-supported filter carrier is treated in the acid treatment tank by the above-mentioned process, And washing and drying it.
