Description

TECHNICAL FIELD The present invention relates to an air pollution monitoring system and a monitoring method using the ultraviolet air sterilizer,

The present invention relates to a sterilization and air pollution monitoring system for removing microorganisms present in air in a specific space by using ultraviolet rays. The sterilization and air pollution monitoring system includes an ultraviolet air sterilizer for spatially monitoring air pollution caused by sterilization of the sterilizer, The present invention relates to an air pollution monitoring system and a monitoring method using the same.

Recently, various viral avian influenza and bacterial infectious diseases have occurred, and life threatening of many animals is frequently occurred, and some problems of human infection are also occurring. It is not easy to defend against the spread of microorganisms that have already occurred, by constructing various preventive systems and spraying disinfectants in areas where infection is expected.

Microorganisms are small organisms that can not be observed by the naked eye and generally include fungi, protozoa, bacteria, viruses, algae, and the like. One of the widely used means of eradicating microorganisms is ultraviolet ray (UV). Ultraviolet (UV) energy has been used since the early 1900s to kill bacteria and microorganisms. When a sufficient amount of ultraviolet energy is applied, ultraviolet energy can kill microorganisms very effectively. However, when the ultraviolet light level is low and the uniformity of the ultraviolet radiation is insufficient, the ultraviolet ray sterilization effect is remarkably lowered. On the other hand, resistance to ultraviolet rays differs from organism to organism, and some organisms are more resistant to ultraviolet than other organisms. In particular, some organisms that form endospores and are in the semi-dormant state show strong resistance to ultraviolet light. Endogenous spores are known to resist considerably more sterilization techniques including heat, chemicals, x-rays and ultraviolet light.

Conventional ultraviolet sterilization systems have not been able to efficiently and effectively utilize ultraviolet energy to destroy airborne contaminants such as microorganisms below a certain level. Therefore, there is a need for a high energy ultraviolet sterilization system that can have a uniform distribution needed for the most effective process of disinfecting microorganisms in dangerous air and destroying other contaminants.

In addition, in the past, the sterilization system has merely adopted a sterilization system, but this sterilization system has not been provided in an advanced form providing alarms based on constant monitoring.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in more detail with reference to the drawings.

Referring to FIG. 1, the air pollution monitoring system 100 of the present invention includes an ultraviolet air sterilizer 101, an air pollution monitor 110, and an air pollution monitor 110 And a control server 150 connected via a network 130. [ Meanwhile, the air pollution monitor 110 may be connected to a local device of the subscriber installed in the field.

At least one sterilizer 101 and at least one air pollution monitor 110 are installed in each of the sites 1, 2 and 3 and the control server 150 controls the plurality of sites SITE 1 , 2, 3) to provide the air pollution monitoring service of the present invention. FIG. 1 shows an example in which three sites SITE 1, 2 and 3 are connected. Hereinafter, for convenience of explanation, an air pollution monitor 110 installed in the first site SITE 1 and an ultraviolet sterilizer 101 ) Will be mainly described. The sterilizer 101 and the air pollution monitor 110 installed in each of the sites 1, 2 and 3 may be operated independently without being connected to the control server 150 according to the embodiment.

network

The network 130 is a wired or wireless network known in the art and may be one or more networks selected from a public telephone network, a LAN, a wireless LAN, a Bluetooth, a Zigbee, have. In consideration of the current network environment and encryption technology, the control server 150 and the air pollution monitor 110 are connected through a general-purpose IP network such as the Internet rather than a dedicated network using a separate protocol, .

Control server

The control server 150 provides the air pollution monitoring service of the present invention based on the status information provided by the air pollution monitor 110 of each site. First, since the control service of the control server 150 is provided for each site unit, basic information of each site unit is managed. For example, basic information includes subscriber information subscribed on a site basis, subscriber's portable terminal information, setting information for the site-specific monitoring area described below, and the like. Naturally, a plurality of sites may be configured in one subscriber, and a plurality of air pollution monitors 110 and an ultraviolet sterilizer 101 may be disposed in one site. However, .

The control server (150) includes a control function unit (151). The control function unit 151 controls the operation state of the air pollution monitoring unit 110 and the operation state of the air pollution monitoring unit 110 by using 'state information', 'alarm event' and ' (I.e., a subscriber terminal or an on-site manager terminal) while monitoring the state of microbial contamination in the system.

As described below, instead of the pollution tracking unit 313 of the air pollution monitor 110, the control server 150 may track the air pollution path using an alarm event received within a predetermined time range.

Ultraviolet Sterilizer

The sterilizer 101 forms a path of air that is sealed, and sterilizes microorganisms in the air by using ultraviolet rays. To this end, the present invention proposes a sterilizer 101 structure that can significantly increase the intensity and uniformity of ultraviolet energy (UV energy) in the sterilizer 101, thereby providing a significantly higher and uniform amount of ultraviolet radiation.

The sterilizer 101 includes a chamber 210 containing an ultraviolet light source 231 and a sterilizer controller 250 for providing operating power of the ultraviolet light source 231. The sterilizer controller 250 may be fabricated integrally with the chamber 210 or may be manufactured and installed separately from the chamber 210.

The chamber 210 forms a closed internal space 210a and is disposed on a closed path through which air flows according to an internal air conditioning system such as a building, thereby forming a part of an air movement path in the field. The chamber 210 sterilizes the microorganisms present in the air flowing into the internal space 210a and discharges the cleaned air. An ultraviolet light source 231 is embedded in the internal space 210a of the chamber 210 to sterilize microorganisms in the air.

The chamber 210 is provided with an input portion 211 provided on the side where air is introduced into the internal space portion 210a and an output portion 213 provided on the side from which the air in the internal space portion 210a is discharged to the outside . The input unit 211 and the output unit 213 are implemented by, for example, a flat panel to seal the internal space 210a, a plurality of intake through holes 211a through which air is introduced into the input unit 211, A plurality of exhaust through holes 213a through which the internal air is discharged are formed in the portion 213. Since the input unit 211 and the output unit 213 are functionally named based on the flow of air and the flow of air does not flow in only one direction, when the flow of air is changed, the input unit 211 and the output unit 213, Lt; RTI ID = 0.0 > 213 < / RTI >

Because sterilization of an organism depends heavily on the amount of ultraviolet energy delivered to the organism, ultraviolet light illumination at or above a predetermined magnitude at any point in the chamber 210 is required to achieve sufficient and effective sterilization in the chamber 210 A dose is required. The present invention utilizes a chamber structure to achieve ultraviolet radiation dose of at least 75,000 cps / cm 2 at any arbitrary location in the chamber 210, preferably at least 100,000 cps / cm 2 or at least 150,000 cps / Investigation is effective. The maximum amount of ultraviolet radiation irradiated to the microorganisms flowing into the chamber 210 varies depending on the residence time of the air. Assuming that the air stays in the chamber 210 for less than 2 seconds under the condition that the ultraviolet ray of 75,000 psi / cm 2 is irradiated, the sterilizer 101 provides the inflow air with an ultraviolet ray dose of at least 150,000 psi · sec / . Here, the UV dose is a measure of ultraviolet energy per unit area for microorganisms, such as UV energy density (E), in units of ㎼ · sec / cm 2.

The ultraviolet illuminance in the chamber 210 is naturally influenced by the illuminance of the ultraviolet light source 231 itself but is not sufficient as the illuminance of the ultraviolet light source 231 itself, It is difficult to create a uniform illumination space.

In order to solve this problem, in the present invention, a reflection plate 215 is provided on the entire inner wall of the chamber 210. The sealed chamber 210 and the reflection plate 215 accumulate and enhance the ultraviolet energy in the internal space portion 210a together with the effect of blocking the ultraviolet energy emitted from the ultraviolet light source 231. [ The chamber 210 of the present invention can increase ultraviolet light intensity in the chamber 210 from 10 times to almost 50 times as compared with the case where only a simple ultraviolet light source is used and uniformity of illumination is improved.

The ultraviolet light source 231 may be provided with a reflective reflector as in normal illumination, but such reflective reflector is installed in the lamp and is not installed in the entire space. The reflector 215 of the present invention is installed over the entire inner space 210a which is a closed space. It is preferable that the reflector 215 is installed at 95% or more, preferably 99% or more of the total surface area of the inner wall of the chamber 210.

The reflection plate 215 is preferably capable of scattering and / or reflecting at least 95% of the ultraviolet light emitted from the ultraviolet light source 231. The reflection plate 215 may be formed by a method of attaching a panel of a material having ultraviolet reflection characteristics or applying a paste of a material having a reflection characteristic to the inner wall of the chamber 210, ) Or the like may be installed. For example, the reflector 215 can be implemented with mirror-polished aluminum or chemically polished and anodized aluminum material.

The size and number of the intake through holes 211a and the exhaust through holes 213a of the chamber 210 may affect the residence time of the air and may also affect the accumulation ability of the ultraviolet energy in the chamber 210 . For example, the ratio of the intake through hole 211a in the input unit 211 and the exhaust through hole 213a in the output unit 213 are respectively less than 40%, and the residence time in the chamber 210 of the air It is desirable to increase the air retention time and the energy accumulation efficiency by, for example, implementing less than 10%.

The ultraviolet light source 231 may use ultraviolet rays in the band of 220 to 300 nm and may use a low pressure mercury discharge lamp that emits continuous and narrow ultraviolet rays. The ultraviolet light source 231 is fixed and electrically connected to the outside of the chamber 210 through a fixing-through hole formed in a wall of the chamber 210 or an end panel. 2 shows an example in which two ultraviolet light sources 231 are installed. The ultraviolet light source 231 may be installed in any manner within the chamber 210. However, for the uniformity of ultraviolet light illumination, It is preferable to arrange it along the main direction in which the air flows.

The sterilizer controller 250 supplies operating power to the ultraviolet light source 231 and controls the overall operation of the sterilizer 101. As described above, the sterilizer controller 250 may be fabricated integrally with the chamber 210, or may be manufactured separately from the chamber 210.

The sterilizer controller 250 controls the operation of the sterilizer 101 according to a basic control algorithm. Here, the basic control algorithm is to control the ultraviolet illuminance within a predetermined range by using a sensor (not shown) installed in the chamber 210 to provide a constant illuminance to the chamber 210 by turning on the ultraviolet light source 231, And the like.

According to an embodiment, the sterilizer controller 250 may provide information on the operating condition to the air pollution monitor 110 and may change the operating mode or change the control method under the control of the air pollution monitor 110 .

The sterilizer controller 250 connects a photosensor (not shown) disposed in the chamber 210 to check the operation state of the ultraviolet light source 231 in the chamber 210 And can provide status information to the air pollution monitor 110 if the ultraviolet light intensity output from the ultraviolet light source 231 does not fall within a predetermined value range.

The sterilizer 101 is generally installed in a form buried without being exposed to the space. A building, a house, or the like, may be installed in an inner duct (duct) 10 as a part of a building air conditioning system. For example, it is preferable that the enclosed facility of the farm for breeding algae is installed on a path where the outside air and the inside air flow in association with each other by being connected to the air inflow device of the facility.
