Description

Air purifying system for livestock using ozone and OH radicals {Air purifying system}

The present invention relates to an air purification system, and more particularly, a shaft using ozone and OH radicals capable of deodorizing and sterilizing air discharged from an odor generating source such as a livestock using ozone and OH radicals (hydroxy radicals). It relates to a used air purification system.

The livestock house usually raises a large number of livestock within a limited space, and the air in the livestock is contaminated by feed or animal excrement, so air pollution due to odor and dust is serious, and in addition, the density of various bacteria and viruses increases. there is a problem.

In order for livestock to grow well in the shed, it is important to keep the air in the shed through ventilation. The air discharged from the shed has a strong odor and is in a state of high density of viruses and bacteria as described above. It will have a very bad effect. In particular, residents living near the barn are very much suffering from odors, so the barn house is inevitably regarded as an evacuation facility.

Various technologies are being researched and developed to solve the problem of odor and pollution in such livestock houses. As one method to eliminate contamination of the livestock air, many studies have been conducted on sterilization and odor removal by ozone, and many products using this have been made. In particular, a method of removing pollutants such as odor components or volatile organic compounds contained in the air by ozone generated by using a low-temperature plasma reaction is still applied to some livestock houses. However, although ozone has the same effect as odor removal and sterilization, it is harmful to livestock and human body, so when using ozone, management of manpower and livestock inside the livestock house was essential.

Another technique for removing odor and killing odor was proposed by dissolving ozone in water stored in a water tank to generate'ozone water' and spraying this ozone water into the house to remove odor. When ozone is dissolved in water, OH radicals are formed, which are highly chemically active and are known to cause chemical reactions with bacteria, viruses, fungi, and various harmful gaseous substances that generate odors in air or water to oxidize them. The decomposition rate of ozone is greatly affected by pH because it has a self-decomposition property that can be decomposed by OH radicals. In other words, ozone is maintained in a stable state in acidic conditions, but the decomposition rate increases as it becomes alkaline. And ozone is decomposed by the initial formed OH radical starting hydroperoxy radical into an intermediate-producing material (HO ₂ ^-) generate OH radicals through the medium path, superoxide radical (O ₂ ^{- -),} ozonide radical (O ₃₎ It is done.

However, since the safety of the OH radicals is also not guaranteed, it is necessary to manage manpower and livestock existing in the livestock when spraying in the livestock. Furthermore, the half-life of OH radicals in water is known to be around 20 minutes, and the ratio of OH radicals decomposed between the time from the ozone dissolution process to the actual spraying process is significant, and is actually used for odor removal/sterilization. Since the amount of OH radicals is significantly reduced compared to the amount of OH radicals generated by the dissolution of ozone, there is a problem that efficient odor removal and sterilization treatment cannot be performed.

The air purification system 10 for livestock using ozone and OH radicals of the present embodiment includes an exhaust unit 100 for discharging indoor air from a pollutant source to the outside, and an exhaust unit 100 to treat the air discharged through the exhaust unit 100. An air treatment unit 200 provided at one side, a partition unit 300 installed in the air treatment unit 200, a first ozone generating unit 400 installed in the air treatment unit 200, and an air treatment unit 200 A droplet injection unit 500 for injecting droplets into the air, an air discharge unit 630 for discharging air to the outside of the air treatment unit 200, and for processing the air discharged through the air discharge unit 630 And a second ozone generating unit 700.

In this embodiment, the pollutant source is a livestock house 1 for raising livestock, and the exhaust part 100 includes an exhaust pipe extending from the inside of the house 1 to discharge the air inside the house 1 to the outside. . In addition, the exhaust unit 100 is provided with an exhaust blower 110 for discharging the air inside the housing 1 to the outside of the housing 1.

The air treatment unit 200 is installed to be adjacent to the axis, which is a pollutant source, in order to provide a treatment space in which contaminated air discharged through the exhaust unit 100 can be treated with odor and sterilization first.

The air treatment unit 200 is formed through a frame and a cover member such as glass or vinyl on one side of the barn 1 so as to form a closed space. The air treatment unit 200 may be formed of various materials capable of forming an enclosed space, and in this embodiment, the air treatment unit 200 is formed to have an arc-shaped cross-sectional shape, but the shape of the air treatment unit 200 The size and size are not limited thereto and may be variously formed.

A partition part 300 is formed inside the air treatment part 200, and the partition part 300 defines the internal space of the air treatment part 200 as a first treatment space 210 and a second treatment space 220. It is divided into.

In the first processing space 210, since the outlet 412 of the exhaust unit 100 is located, air discharged from the pollutant source by the exhaust unit 100 is first introduced into the first processing space 210.

As described above, the second processing space 220 is partitioned from the first processing space 210 by the partition unit 300 and is a space in contact with the inner circumferential surface of the air processing unit 200.

Since a plurality of ventilation holes 310 having a predetermined diameter are formed in the partition part 300, air from the first treatment space 210 may be introduced into the second treatment space 220, and the partition part 300 May be formed of a porous film material in which a plurality of the ventilation holes 310 are formed, or may be formed of a predetermined porous plate material. When a porous film is applied, a separate auxiliary frame for installing the porous film may be further provided inside the air treatment unit 200.

The first ozone generating unit 400 is provided to be located inside the air treatment unit 200, more specifically, in the first treatment space 210.

As shown in FIG. 3, the first ozone generating unit 400 has a first ozone generator 420 installed inside the main body 410 after air is sucked into the main body 410 through an inlet 411. ) Is formed in a form that can be discharged to the outside through the discharge port 412 together with the ozone generated from.

The first ozone generator 420 generates ozone using a plasma discharge method. When the power supply port 421 supplies power to the electric conductor 422 as shown in the enlarged view of FIG. 2, the ceramic tube Plasma is generated between 423 and the electric conductor 422, and the plasma generates ozone again.

Ozone generated by the ozone generator removes odor factors and microorganisms such as bacteria and viruses contained in the air to deodorize and sterilize.

The droplet spraying unit 500 is formed to spray fine water droplets into the interior space of the air processing unit 200, particularly the first processing space 210. The fine water droplets sprayed from the droplet spraying unit 500 remove odor components having hydrophilic polarity such as ammonia, amines, ketones, aldehydes, lower organic acids, and phenols in the polluted air discharged from the exhaust unit 100 Do it.

In particular, the water droplets sprayed from the droplet spraying unit 500 become water in which OH radicals, also referred to as ozone water, are formed while ozone generated in the first ozone generating unit 400 is dissolved. Since OH radicals have better oxidizing power than ozone, odor removal and sterilization effects are maximized.

Although not shown, the inside of the air treatment part 200 is inside the air treatment part 200 so that the minute water droplets sprayed from the droplet spraying part 500 do not sink directly to the floor and extend the time to stay in the air. An upward airflow forming part 610 for forming an upward airflow may be further provided, and various means such as a fan, a blower, and a circulator may be applied to the upward airflow forming part 610.

Furthermore, in order to increase the generation rate of OH radicals when ozone and droplets meet, a UV light irradiation unit 620 may be installed in the processing space 100, and the ultraviolet rays irradiated from the UV light irradiation unit 620 are OH radicals. It is helpful in the production of, and itself can have the effect of sterilizing microorganisms in the air.

In the second processing space 220, air which has been deodorized and sterilized by the first ozone generating unit 400 and the droplet spraying unit 500 is introduced from the first processing space 210, and the second processing space ( The air introduced into 220 is discharged to the outside of the air treatment unit 200 through the air discharge unit 630.

The residence time of the air in the first processing space 210 may be determined by the size or number of the ventilation holes 310 formed in the partition plate. If the ventilation holes 310 are too large or too large, the first processing space In (210), the residence time of air is short, so deodorization and sterilization by ozone and OH radicals are not sufficiently achieved. Conversely, if the ventilation hole 310 is too small or its size is very small, the air cannot move from the first processing space 210 to the second processing space 220 and the pressure in the first processing space 210 becomes excessively high. As a result, there may be a problem in that the internal air of the pollutant cannot be quickly discharged.

Therefore, it is preferable that the ventilation holes 310 of the partition unit 300 are formed in a size and number capable of moving to the second processing space 220 after the contaminated air is sufficiently deodorized and sterilized.

A second ozone generating unit 700 is connected to the air discharge unit 630.

In addition, the control unit 800 receives odor information of the air discharged to the outside through the second odor sensor 820 installed in the final discharge unit 740, and the measured value measured by the second odor sensor 820 is less than the reference value. In this case, the first on-off valve 742 is opened to exhaust air to the outside. However, if the measured value measured by the second odor sensor 820 is higher than the reference value, the first opening/closing valve 742 is closed, the second opening/closing valve 751 is opened, and the return blower 752 is operated to operate the final discharge unit 740. ) Is returned to the first treatment space 210 of the air treatment unit 200 so that the air can be sterilized and deodorized again.
