Description

Odor reducer and odor reducer spraying device {DEODORIZING AGENT AND APPARATUS FOR SPRAYING THE SAME}

The present invention relates to a medicament for reducing malodor and a device for dispensing the same.

Recently, environmental problems such as climate warming have been greatly highlighted worldwide. Accordingly, Korea is also establishing environmental policies in various ways in response to this. These environmental policies have the main goal of realizing a low-carbon society, and in order to achieve this goal, policies that require recycling in each industry are being promoted.

As part of this recycling policy, the ascon industry is promoting a plan to recycle waste ascon instead of aggregate. Specifically, according to the Act on the Promotion of Recycling of Construction Waste, public institutions such as the state or local governments are obliged to use recycled aggregates such as waste ascon or recycled aggregate recycled products when carrying out construction projects of a certain scale or more. . Here, recycled aggregate recycled products refer to products using 25% or more of recycled aggregate in the case of asphalt concrete products.

In addition to the mandatory recycling of recycled aggregate, the recent revision of the Construction Waste Act has gradually increased the mandatory use of recycled ascon (recycled aggregate), which is expected to rise from 25% in the past to a level far exceeding 40%. do. These regulations may seem rather strict, but compared to developed countries such as the EU, which is expected to expand to more than 70%, Korea's mandatory use of recycled ascon is still at a low level. Looking specifically at the current status of advanced countries, as of 2019, Japan shows 76%, the Netherlands 70%, Denmark 58%, Belgium 51%, etc., while the use rate of recycled ascon in Korea is still 9.1%. are staying in

As a result, the proportion of mandatory use of recycled aggregates under national laws is expected to continue to rise in the future. Accordingly, domestic ascon companies are also rapidly replacing waste ascon with aggregate for production of ascon in order to meet the regulatory standards set forth in the Building Waste Act.

However, when the waste ascon is used as an aggregate for producing ascon, there is a problem in that a serious level of odor is generated. Specifically, the asphalt industry uses asphalt (bitumen) and aggregates, which are products of oil refineries, as main raw materials, and harmful gases are unavoidably generated due to asphalt, which is a by-product of oil refineries. More specifically, since the asphalt factory uses mostly recycled oil or bunker oil as a fuel for heating and mixing aggregate and asphalt, and the heating temperature also maintains an incomplete combustion state between 150 ° C and 200 ° C, the ascon industry It can be said to be a representative odor-causing industry. In addition, unlike a new asphalt production plant that mixes new asphalt and aggregate, a recycled asphalt production plant that uses recycled aggregate such as waste asphalt generates a much more serious level of odor. In this way, the mandatory use of recycled asphalt concrete, on the other hand, causes another problem of high concentration of odor generation.

On the other hand, problems caused by such odors are regulated by another regulation, the Anti-Odor Act. Specifically, the Odor Prevention Act limits the concentration of odor that can be discharged from the odor generating source so that residents near the odor generating place are not harmed by the odor. More specifically, looking at the emission standards of the odor prevention law set by local governments such as special cities, metropolitan cities, and special self-governing provinces, a dilution factor of 1,000 times or less in the case of industrial complexes based on the measurement at the odor outlet, and non-industrial complexes In the case of , it is stipulated that a dilution factor of 500 times or less should be satisfied.

Under the above regulations, ascon producers, currently more than 85% of which are located in non-industrial complexes, must meet the more stringent emission limit, a dilution factor of less than 500 times. If the emission standards are not met and caught for the 4th time, the business will be suspended according to the Odor Prevention Act.

As described above, currently many ascon companies are obliged to use recycled aggregate according to the Construction Waste Act, and on the other hand, must also meet the odor emission standards according to the Odor Prevention Act. It is very difficult to solve the odor problem at the same time, and most companies are experiencing considerable difficulties.

Accordingly, various methods for solving the odor problem have been attempted. One of these methods is to use a chemical substance such as chlorine dioxide as an odor eliminator. However, there is a growing opinion that these chlorine-based odor eliminators are currently inappropriate as chlorine-based odor eliminators due to toxicity and inherent odor problems. For this reason, some of the ascon companies urgently needing to remove the odor used chlorine dioxide, sodium hypochlorite, or hydrochloric acid as an odor remover, but most of them have stopped using them due to the above-mentioned problems and performance limitations. On the other hand, as a different method, a technology for removing odors by equipment is continuously developed, but it is not spread due to high construction cost and limitations in odor removal performance.

On the other hand, as another method, a method of utilizing an amine-based compound as an odor remover has also been proposed. Specifically, it is a method of using a tertiary amine-based compound, which has been applied for the process of removing volatile organic compounds in an oil refinery or for the removal of odors caused by harmful gases from coal in coal power plants, as an odor remover in the production of ascon. However, amine-based compounds generate nitrogen oxides when removing odors, and unlike coal power plants or steel mills, ascon plants do not have denitrification facilities, so it is not suitable to apply amine-based compounds that are effective in removing odors.

As described above, a harmless odor reducer that can solve the odor problem caused by the current mandatory use of waste ascon and meet the emission standards under the Odor Prevention Act, but without the high odor and toxicity problems caused by chlorine-based odor reducers development is very urgent.

On the other hand, the odor reduction agent is commonly used in other fields besides the above-described asphalt concrete plant. Specifically, odor reducers are used not only in garbage incinerators and pig farms, which generate many civil complaints, but also in indoor coal storage facilities. In particular, the odor reducing agent used in pig farms must be harmless so as not to affect livestock in the barn. If a harmless odor reducer that is not harmful to the human body and the environment is developed, it will be widely used in other fields besides the above-described ascon process.

In addition, in addition to the ascon factory, the above-described indoor coal storage facilities have recently been highlighted with problems due to odor. Specifically, coal stored in indoor coal storage facilities absorbs oxygen in the air during unloading and transportation, resulting in an autoxidation phenomenon in which heat is generated. do. The odor problem of such an indoor coal storage facility has recently been greatly highlighted along with the above-mentioned odor problem of an ascon plant, and a pharmaceutical solution to cope with it is also required.

On the other hand, in addition to the odor reducing agent as described above, equipment for spraying it is also required. Conventional malodor removal equipment has not been widely spread due to high construction costs and limitations in odor removal performance. In order to improve this problem, it is necessary to develop a simple and economical spraying facility in which a malodor reducing agent is directly sprayed into a factory discharge port where malodor is discharged.

One object of the present invention is to provide an odor reducer capable of reducing a high concentration of odor generated due to reuse of recycled aggregate in the production of recycled asphalt concrete.

Objects and effects of the present invention, and technical configurations for achieving them will become clear with reference to the embodiments described later in detail in conjunction with the accompanying drawings. In describing the present invention, if it is determined that a detailed description of a known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description will be omitted. In addition, terms to be described later are terms defined in consideration of functions in the present invention, which may vary according to the intention or custom of a user or operator.

However, the present invention is not limited to the embodiments disclosed below and may be implemented in a variety of different forms. Only these embodiments are provided to complete the disclosure of the present invention and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined by the scope of the claims. only become Therefore, the definition should be made based on the contents throughout this specification.

Throughout the specification, when a part "includes" or "includes" a certain component, it means that it may further include other components without excluding other components unless otherwise stated. . In addition, terms such as "...unit" or "...module" described in the specification mean a unit that processes at least one function or operation, which may be implemented as hardware, software, or a combination of hardware and software. there is.

Hereinafter, a malodor reducing agent and a malodor reducing agent injection device according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. In this specification, the same or similar reference numerals are assigned to the same or similar components even in different embodiments, and the description is replaced with the first description.

The odor reducing agent according to an embodiment of the present invention may include a microbial-based aqueous solution, a mineral-based aqueous solution, and a phytoncide aqueous solution. These may be configured to be mixed with each other when sprayed toward malodorous gases while each is stored in a separate tank. The weight ratio of these to each other may account for 50 to 90 parts by weight of a microbial-based aqueous solution, 10 to 50 parts by weight of a mineral-based aqueous solution, and 5 to 40 parts by weight of an aqueous phytoncide solution with respect to 100 parts by weight of the odor reducing agent. As an example, the microbial-based aqueous solution and the mineral-based aqueous solution may be used in a ratio of about 3:1. Here, the odor reducing agent may be used except for the phytoncide aqueous solution depending on the case.

A detailed description of each of the above aqueous solutions is as follows.

First, the microbial-based aqueous solution may be composed of microorganisms including lactic acid bacteria and water. Here, the microorganism may occupy 0.5 to 5 parts by weight based on 100 parts by weight of the microbial-based aqueous solution. Microorganisms are described in detail as follows.

Here, the microorganism may be composed of a complex lactic acid bacteria in which several species of lactic acid bacteria having an environmental purification effect are mixed. The strains constituting these complex lactic acid bacteria generally have an effect of removing odor-causing substances such as ammonia and hydrogen sulfide.

Specifically, the microorganisms contained in the microbial-based aqueous solution are Lactobacillus satsumensis, Lactobacillus mali, Lactobacillus nagelii, Lactobacillus buchneri, Leuconostoc Mesenteroides, Lactobacillus parafarraginis, Lactobacillus rapi, Lactobacillus parabuchneri, Lactobacillus rhamnosus, Lactobacillus paracasei (Lactobacillus paracasei), Candida ethanolica and Acetobacter peroxydans. A detailed description of these effects is as follows.

First, Lactobacillus satumensis, Lactobacillus nageli, and Lactobacillus dried are known to have excellent antibacterial effects. In particular, dried lactobacillus is known to have excellent antibacterial effects against harmful bacteria such as E. coli, S. typhimurium, Staphylococcus aureus, and S. gallinarium.

In addition, Lactobacillus satumensis, Lactobacillus mali, Lactobacillus nageli, Leuconostoc mesenteroides, and Candida ethanolica are effective in removing ammonia that may cause odor.

On the other hand, among them, Lactobacillus satumensis, Lactobacillus mali, and Lactobacillus nageli show very good efficacy in removing hydrogen sulfide, a representative odorous substance. In addition, acetobacter peroxidans has an effect of removing heavy metals.

In addition, Lactobacillus buchineri, Leuconostoc mesenteroides, and Lactobacillus raffi inhibit spoilage microorganisms and harmful microorganisms, and the above-described Lactobacillus paraparaginis and Lactobacillus parabuchineri increase dissolved oxygen in water quality, and water quality It has the effect of improving pollution and removing bad odor from water quality.

Among the above-mentioned microorganisms, Leuconostoc mesenteroides, Lactobacillus rhamnosus, Lactobacillus paracasei, and Acetobacter peroxidans have particularly excellent effects in removing various kinds of odor substances.

On the other hand, the microbial-based aqueous solution is configured such that the above-described lactic acid bacteria each have a predetermined weight ratio. Specifically, based on 100 parts by weight of the microorganisms contained in the microbial aqueous solution, 11 to 45 parts by weight of Lactobacillus paraparaginis, 7 to 30 parts by weight of Lactobacillus butchineri, 0.5 to 2 parts by weight of Lactobacillus satumensis, Leukono 0.5 to 2 parts by weight of stock mecenteroides, 0.5 to 2 parts by weight of Lactobacillus mali, 0.5 to 2 parts by weight of Lactobacillus raffi, 0.5 to 2 parts by weight of Lactobacillus parabuchineri, 0.3 to 1.5 parts by weight of Lactobacillus rhamnosus, lactobacillus 2 to 7 parts by weight of Bacillus paracasei, 0.5 to 2 parts by weight of Candida ethanolica, 0.5 to 2 parts by weight of Acetobacter peroxidans and 0.5 to 2 parts by weight of Lactobacillus nageli.

As described above, Lactobacillus paraparaginis has a specific effect on removing water odor, so it is particularly suitable for spraying in an aqueous solution according to an embodiment of the present invention and has a higher weight ratio than other strains. On the other hand, since Lactobacillus paracasei also has a specific effect on odor removal as described above, it has a slightly higher weight ratio than other strains.

Hereinafter, the mineral-based aqueous solution will be described in detail.

The mineral-based aqueous solution functions to reduce odor by itself by reacting with odor-causing substances, but also performs the function of maximizing the odor removal reaction by being mixed with the above-described microbial-based aqueous solution.

The mineral-based aqueous solution may be composed of minerals and water. Here, the mineral may account for 0.3 to 3 parts by weight based on 100 parts by weight of the microbial-based aqueous solution.

Minerals may include elements such as sodium or potassium, in addition to lithium, magnesium, aluminum, silicon, calcium, nickel, copper, zinc, and the like, and may also include silicon dioxide (SiO ₂ ).

This mineral-based aqueous solution can perform a odor reduction function by itself. Specifically, the mineral-based aqueous solution dissolves odor-causing substances such as ammonia, trimethylamine, hydrogen sulfide, and methyl mercaptan from odor gas to perform the function of an odor reducer. For example, sodium is converted into sodium sulfide and water by combining with hydrogen sulfide in an aqueous solution (H ₂ S + 2NaOH → Na ₂ S + 2H ₂ O). In addition, when combined with methyl mercaptan, it is converted to sodium methanethiolate and water (CH ₃ SH + NaOH → CH ₃ SNa + H ₂ O).

Meanwhile, the mineral-based aqueous solution also functions to amplify the odor removal reaction of the above-described microbial-based aqueous solution, which will be described later with reference to FIG. 1 .

Hereinafter, the phytoncide aqueous solution will be described in detail.

The phytoncide aqueous solution also performs the odor reduction function by itself, and also performs the function of maximizing the odor removal reaction by being mixed with the above-described microbial-based aqueous solution and mineral-based aqueous solution.

Such an aqueous phytoncide solution may be composed of phytoncide, a vegetable emulsifier and water. Here, the phytoncide and vegetable emulsifier may contain 0.3 to 5 parts by weight and 0.2 to 3 parts by weight, respectively, based on 100 parts by weight of the phytoncide aqueous solution.

For phytoncide, pine nut oil extracted from pine nuts and the like can be used. Phytoncide extracted from pine trees is composed of terpenes, alkaloids, and planoids. These phytoncides emit aromatic substances beneficial to humans and provide a fresh scent. In particular, the terpene is a flammable unsaturated hydrocarbon widely distributed in animals and plants, and is known to have a very high removal rate of formaldehyde. Specifically, terpenes are a general term for carbohydrates and derivatives thereof having the general formula (C ₅ H ₈ )n (n≥2), and are classified according to the number of isoprene (C ₅ H ₈ ) units in a molecule. 2 monoterpenes (C ₁₀ H ₁₆ ), 3 sesquiterpenes (C ₁₅ H ₂₄ ), 4 diterpenes (C ₂₀ H ₃₂ ), 6 triterpenes (C ₃₀ H ₄₈ ), tetra A terpene (C ₄₀ H ₆₄ ) has eight isoprene units each. These terpenes are hydrophobic and do not mix well with water.

To this end, the phytoncide aqueous solution contains a vegetable emulsifier. Vegetable emulsifiers combine with phytoncide to help emulsify phytoncide into water. As the vegetable emulsifier, vegetable fatty acids such as sucrose fatty acid esters may be used.

This phytoncide aqueous solution can perform the odor reduction function by itself. Specifically, phytoncide decomposes odor-causing substances by chemically combining with odor components and neutralizing them. In other words, phytoncide is not only perfect but also safe because it decomposes the cause of odor according to the reaction formula of A (phytoncide) + B (odor-causing substance) = C. Due to this chemical neutralization, in the case of a pine tree forest, the carcasses of animals rot and there is a lot of excrement, but there is no bad smell. This is because phytoncide combines with animal carcasses and the causes of all decaying odors, fundamentally decomposes the causes of odors, and converts them into substances beneficial to trees.

On the other hand, the phytoncide aqueous solution also functions to amplify the odor removal reaction of the above-described microbial-based aqueous solution and mineral-based aqueous solution, which will be described later with reference to FIG. 1.

Meanwhile, the odor reducing agent may further include an amine-based compound. Specifically, methyldiethanolamine (MDEA), a tertiary amine-based material, may be additionally used. However, as described above, amine-based compounds generate nitrogen oxides when removing odors, so they can be used in coal-fired power plants or steel mills equipped with separate denitrification facilities rather than ascon factories without denitrification facilities.

Such an amine-based compound can reduce odor by suppressing activation of odor-causing substances having a small molecular weight through a high molecular weight. Specifically, in the case of hydrogen sulfide, H ₂ S + In → HS- (radical formation) → H ₂ S ₂ or HSIn (where In is an amine compound), and in the case of carbon disulfide, CS ₂ + In → CSIn or CS- In the case of dimethyl sulfide, odor is reduced through the reaction of C ₂ H ₆ S + In → C ₂ H ₆ S- (radical formation) → C ₂ SC ₂ S. do.

Hereinafter, a device for spraying the odor reducing agent described above will be described in detail with reference to FIG. 1 .

1 is a view for explaining an odor reducer injection device 100 according to an embodiment of the present invention.

Referring to this figure, the odor reducing agent injection device 100 includes an aqueous solution tank 110, a water tank 120, a main pipe 130, a sub pipe 140, a drug injector 150, a nozzle 160, and A warming module 170 may be included.

The aqueous solution tank 110 is a configuration for separately storing the above-mentioned drugs. To this end, the aqueous solution tank 110 includes a first tank 111, a second tank 112, and a third tank 113. The first tank 111 stores a microbial-based aqueous solution, the second tank 112 stores a mineral-based aqueous solution, and the third tank 113 stores a phytoncide aqueous solution.

The water tank 120 stores water for diluting and spraying the aforementioned aqueous solutions.

The main pipe 130 is connected to the water tank 120 to pump water in the water tank 120 . The main pipe 130 includes a first main pipe 131, a second main pipe 132, and a third main pipe 133 so that the three aqueous solutions described above can be separately diluted and pumped.

The sub pipe 140 is a configuration for connecting the aqueous solution tank 110 and the main pipe 130. The subpipe 140 also includes a first subpipe 141, a second subpipe 142, and a third subpipe 143 so that each of the aqueous solutions can be joined to the three main pipes 130, respectively.

The drug injector 150 is configured to adjust the amount of the aqueous solution so that it can be joined to the main pipe 130. The drug injector 150 is also installed in the first sub-pipe 141, the second sub-pipe 142, and the third sub-pipe 143 so that the amounts of the three aqueous solutions can be respectively adjusted and transferred.

The nozzle 160 is a configuration for spraying the above-described aqueous solution. The nozzle 160 includes a first nozzle 161, a second nozzle 162, and a third nozzle 163 to spray three aqueous solutions, respectively. The first nozzle 161 is connected to the first main pipe 131 to spray the microbial-based aqueous solution, the second nozzle 162 is connected to the second main pipe 132 to spray the mineral-based aqueous solution, and the third The nozzle 163 is connected to the third main pipe 133 to spray the phytoncide aqueous solution. The first nozzle 161, the second nozzle 162, and the third nozzle 163 are spaced apart from each other at equal intervals on the inner circumferential surface of the outlet Q through which the odor gas is discharged, and are disposed in the center area of the outlet Q. It is configured to spray an aqueous solution toward

The warming module 170 is a component for maintaining the microbial-based aqueous solution at a temperature close to room temperature. Microorganisms in the microbial-based aqueous solution may be less active or die at very low or very high temperatures. The thermal insulation module 170 is configured to prevent this by maintaining the temperature of the microbial-based aqueous solution at 5°C to 40°C.

To this end, the warming module 170 may include a heat conduction layer 171 , a heating layer 172 , and a heat shielding layer 173 . The heat conductive layer 171 is configured to surround the outer surface of the first tank 111 and the outer surface of the first subpipe 141 . For the thermal conductive layer 171 , a thermal tape in the form of acrylic foam containing a ceramic filler or a graphite pad may be used. The heating layer 172 is configured to surround the heat conducting layer 171 . The heating layer 172 may be formed of alloy wires such as copper, nickel, and chromium, which are common heating elements. The heating layer 172 generates heat by receiving power from the outside, and the heat is transferred to the first tank 111 and the first subpipe 141 through the heat conducting layer 171 . The heat shielding layer 173 is configured to surround the heating layer 172 . The heat shielding layer 173 may be made of expanded polystyrene or the like.

Through this configuration, the warming module 170 activates the heating layer 172 when the temperature of the microbial-based aqueous solution drops below 5° C. in winter to maintain the temperature of the microbial-based aqueous solution at 5° C. or higher to activate microorganisms. can help For this control, a water temperature measuring sensor and a relay may be further provided. In addition, in the summer season, the heat shielding layer 173 can prevent the temperature of the microbial-based aqueous solution from increasing to 40° C. or higher by blocking external heat.

The operation method of the odor reducing agent injection device 100 configured as described above is as follows.

First, malodorous gas is discharged from a malodorous source such as the aforementioned asphalt concrete plant to the outside atmosphere through the discharge port Q. These malodorous gases contain odor-causing substances such as hydrogen sulfide.

The malodor reducing agent injection device 100 is configured to directly inject the malodor reducing agent together with water into the malodorous gas. Specifically, the odor reducing agent stored in the aqueous solution tank 110 is joined to the main pipe 130 through the drug injector 150 and the sub pipe 140, and then mixed with water in the main pipe 130 through the nozzle It is injected into the outlet (Q) through (160). According to this configuration, the malodor reducing agent is directly injected toward the malodorous gas, and a rapid malodor reduction effect can be obtained within a short time of about 30 seconds to 1 minute.

Here, the mixing ratio of the microbial-based aqueous solution, the mineral-based aqueous solution, and the phytoncide aqueous solution to water may be 1:10 to 1:10,000. This dilution rate may be appropriately adjusted according to the concentration of the malodorous gas discharged from the outlet Q.

Meanwhile, the dilution ratio of each of the microbial-based aqueous solution, the mineral-based aqueous solution, and the phytoncide aqueous solution may be different from each other. Specifically, when the dilution ratio of the microbial-based aqueous solution to water is 1:100, the dilution ratio of the mineral-based aqueous solution to water is adjusted to 1:300, resulting in a mixing ratio of the microbial-based aqueous solution and the mineral-based aqueous solution of 3 :1 may be adjusted. In this way, depending on conditions, the drug injector 150 of the third tank 113 may be blocked so that the phytoncide aqueous solution is not sprayed.

Meanwhile, through this process, the microbial-based aqueous solution, the mineral-based aqueous solution, and the phytoncide aqueous solution are in the form of fine droplets into the discharge port Q through the first nozzle 161, the second nozzle 162, and the third nozzle 163, respectively. is sprayed Here, the first nozzle 161, the second nozzle 162, and the third nozzle 163 are installed to spray the aqueous solution toward the central region of the discharge port Q, so that the microbial-based aqueous solution, the mineral-based aqueous solution, and the phytoncide aqueous solution are discharged through the discharge port Q. In (Q), they form a mixed state with each other. Due to this mixed state, the microbial-based aqueous solution, the mineral-based aqueous solution, and the phytoncide aqueous solution have a more amplified odor reduction effect in addition to their respective odor removal effects as described above.

The results of the experiment on the odor reduction effect due to the mutual mixing of these aqueous solutions are as follows.

<Analysis of results of Experimental Example 1 for Comparative Example 1>

First, looking at the results of Comparative Example 1, in the case of the new Ascon process without using recycled aggregate, it can be seen that the odor can be reduced within 500 times the dilution factor specified in the Odor Prevention Act just by spraying the mineral-based aqueous solution. . However, in the case of recycled ascon, which requires the use of recycled aggregate according to the Construction Waste Act, if only the mineral aqueous solution is used as an odor reducer, the dilution ratio exceeds 500 times, showing a result of 1,200 times. You will see unpredictable results.

In contrast, looking at the results of Experimental Example 1 of the odor reducer according to an embodiment of the present invention, it can be seen that even in the regeneration ascon process with a severe odor, the dilution factor is 500 times or less, 420 times. These results can be attributed to the maximization of the odor reduction effect by mixing them together, in addition to the odor reduction function of each of the microbial-based aqueous solution, the mineral-based aqueous solution, and the phytoncide aqueous solution.

Specifically, the malodorous gas discharged through the outlet (Q) proceeds at a high speed of about 10 m/s, and the odor reducer injection device 100 is configured to spray the odor reducer directly into the outlet (Q), It seems to promote the rapid adsorption reaction of the odor reducer and the odor gas. In addition, the microbial-based aqueous solution, the mineral-based aqueous solution, and the phytoncide aqueous solution having different components react with different odor-causing substances, respectively, to remove more species of odor-causing substances, and in addition, during the process of removing odor-causing substances, radical formation and As different aqueous solutions intervene in the same intermediate reaction, it can be seen that each aqueous solution complements the odor removal process to maximize the odor removal efficiency.

As described above, according to the odor reducing agent and the odor reducing agent spraying device according to an embodiment of the present invention, the microbial-based aqueous solution, the mineral-based aqueous solution, and the phytoncide aqueous solution are mixed with each other in the form of fine droplets, so that each aqueous solution is separately It is possible to obtain a much higher odor reduction effect than when the odor gas is sprayed and reacted with each other. In addition, the components constituting the odor reducing agent are composed of microorganisms, minerals and plant extracts, respectively, so that there is no inherent odor problem such as chlorine, and it is harmless to the human body and the environment, so it can be used for livestock.

The malodor reducer and the malodor reducer injection device as described above are not limited to the configurations and operation methods of the embodiments described above. The above embodiments may be configured so that various modifications can be made by selectively combining all or part of each embodiment.
