Description

마찰 정전기 집진장치{A DUST COLLECTOR BY FRICTIONIZE-ELECTROSTATIC}Tribostatic Dust Collector {A DUST COLLECTOR BY FRICTIONIZE-ELECTROSTATIC}

본 발명은 마찰(摩擦) 정전기(靜電氣) 집진(集塵)장치에 관한 것이다.TECHNICAL FIELD This invention relates to a friction electrostatic dust collector.

분진(粉塵)의 집진은, 중력(重力)집진, 원심력(遠心力) 집진, 필터 집진, 관성(慣性) 및 충돌(衝突)집진, 세정(洗淨)집진, 전기(電氣)집진, 음파(音波)집진 등 여러종류의 집진수단이 있다.Dust collection includes gravitational dust collection, centrifugal dust collection, filter dust collection, inertial and collision dust collection, cleaning dust collection, electric dust collection, sound waves There are various kinds of dust collection means such as sound wave collection.

본 발명은 전기집진기술분야에 속하는 마찰 정전기 집진장치에 관한 것이다.The present invention relates to a triboelectric electrostatic precipitator which belongs to the field of electrostatic precipitating technology.

일반적으로 전기집진이라고 하면, 직류 고전압에 의하여 코로나 방전을 발생시키고 공기(가스)중의 분진 입자를 대전(帶電)시키어 이 대전된 입자를 전장(電場)내에서 전기력에 의하여 공기와 분리하는 기구를 가진, 입자(粒子)의 정전(靜電)집진방식을 말한다.In general, electrostatic precipitation includes a mechanism that generates a corona discharge by direct current high voltage, charges dust particles in air (gas), and separates the charged particles from the air by electric force in the electric field. Refers to the electrostatic precipitating method of particles.

전기집진에는 방전극부(放電極部)와 집진극부(集塵極部)가 일체로 된 1 단(段)형 전기집진장치로서 소위 코트렐(Cottrel)장치라고 하는 일반 공업용으로 사용하는 것과, 또 방전극부와 집진극부가 분리 된 2 단형 전기집진장치로서 유해가스의 발생이 적은 공기정화에 주로 사용되는 것이 있다.Electrostatic precipitating is a one-stage type electrostatic precipitator in which the discharge unit and the collecting pole unit are integrated and used for general industrial purposes such as a so-called Cottrel unit. Two-stage type electrostatic precipitator with separate parts and dust collector is mainly used for air purification with low generation of harmful gases.

이때 전기집진장치내에서의 입자에 작용하는 전기력(電氣力)은,At this time, the electric force acting on the particles in the electrostatic precipitator is

(a) 대전입자의 전하(電荷)에 의한 쿨롬(Coulomb)힘(a) Coulomb force due to charge of charged particles

(b) 전계경도(電界傾度)에 의한 힘(b) force by electric field hardness

(c) 입자 상호간의 흡인력(c) attraction between particles

(d) 전기바람(風) 등에 의하는 것으로 알려저 있으며, 이 가운데, 실제적으로 작용하는 것은 주로 쿨롬(Coulomb)힘이 지배적인 것으로 보고 있다.(d) It is known to be caused by electric wind, etc. Among them, the Coulomb force is considered to be the dominant one.

종래의 코로나 방전에 의하여 분진입자를 대전(帶電)시키는 전기집진장치는 입자의 분리 이동속도가, 서브 미크론 범위의 중력(重力), 또는 원심력(遠心力)에 의한 침강(沈降)속도와 같이 급격히 저하되는 일이 없기 때문에 초미립자의 집진에 유효하고 압력손실의 염려도 없는 이점이 있다.In the conventional electrostatic precipitator which charges the dust particles by corona discharge, the separation and moving speed of the particles are rapidly reduced, such as the sedimentation speed by gravity or centrifugal force in the sub-micron range. Since there is no deterioration, it is effective for dust collection of ultrafine particles and has no advantage of pressure loss.

한편, 직류 전압으로는 수천내지 수만 볼트(V)를 사용해야 하며 코로나 방전에 의하여 가스의 국부적인 전리(電離)단계에서 안정적으로 지속하려면 전계(電界)가 현저하게 불편등 되어야 전리 발생조건이 유지되고 코로나 방전에 의하여 최대 전계(電界)강도가 감소해야 안정조건이 유지되는데, 이러한 조건이 충족되지 않으면 방전회로 전체가 파괴되고 아크방전이나 글로우 방전으로 이행(移行)하려는 과도상태에서 불꽃방전이 발생되어, 분진의 연소로 탄소분말이 생기어 2차적으로 공기를 오염할 뿐 아니라 화재의 위험이 있었다.On the other hand, as DC voltage, thousands to tens of thousands of volts should be used, and in order to maintain stable in local ionization phase of gas by corona discharge, electric field condition should be remarkably uncomfortable. When the maximum electric field strength is decreased by corona discharge, stable condition is maintained.If this condition is not satisfied, the entire discharge circuit is destroyed and spark discharge occurs in the transient state to transition to arc discharge or glow discharge. In addition, the combustion of dust produced carbon powder, which not only contaminated the air but also caused a fire.

본 발명의 목적은 공기 정화에 있어서, 정전(靜電)극판과 마찰판과의 회전마찰에 의하여 발생되는 정전기가 분포된 집진판에 필터로 여과하기 어려운 초미립자의 분진을 흡차시키어 공기를 정화하는, 마찰 정전기 집진장치를 제공하려는데 있다.SUMMARY OF THE INVENTION An object of the present invention is to purify air by sucking dust of ultra-fine particles that are difficult to filter with a filter to a dust collecting plate in which static electricity is generated by rotational friction between an electrostatic electrode plate and a friction plate in air purification. I'm trying to provide a device.

본 발명의 또 다른 목적은 종래와 같은 직류의 고전압을 사용하지 않고, 집진판을 겸한 정전극판과 마찰에 의하여 정전기를 이르키는 마찰판을 구동하는 정도의 작은 동력으로 실내공기에 부유된 초미립자의 분진을 흡착하여 간편하게 공기를 청결하게 정화할 수 있게 하려는데 있다.It is still another object of the present invention to eliminate dust of ultra-fine particles suspended in indoor air with a small power such as driving a positive electrode plate serving as a dust collecting plate and a friction plate that causes static electricity by friction, without using a high voltage of a direct current as in the prior art. It is to make it easy to clean the air by adsorption.

본 발명은 일반적으로 잘 알려진 전기적 비도체인 아크릴 수지 등의 합성수지판 등을 면포 등으로 마찰하면 정전기가 발생되는 정전(靜電)극판에 전하(電荷)미립자가 흡착되는 물리적 성질을 본 발명의 목적을 충족할 수 있도록 새로운 공기 정화 수단으로 적용한 것이다.The present invention satisfies the object of the present invention by physically adsorbing charge fine particles to the electrostatic electrode plate which generates static electricity when the synthetic resin plate such as acrylic resin, which is a well-known electrical non-conductor, is rubbed with a cotton cloth or the like. It was applied as a new air purification means.

즉, 필터와 송풍기가 구비된 통풍 가능한 집진실을 구비한 통체(筒體)와,마찰에 의하여 정전기가 발생되는 아크릴 등의 합성수지 재질로 된 정전(靜電)극판을 겸한 집진판과, 이 집진판을 상기 집진실에 소정의 조밀한 간격의 병열로 배치된 다음 이 집진판의 공간내부에 모터로 구동되는 하나의 회전측에 의하여 회전 마찰로 정전기를 이르키는 마찰판으로 결합구성되어 있다. 또한 마찰판의 양면에는 면(棉) 등의 마찰포가 교체가능하게 부착되어 있어, 집진판의 양측 내면과 접찰(接擦)하여 집진판의 양측 표면에 정전기가 발생되어 대전(帶電)된다. 마찰판을 지속적으로 구동하면서 송풍기를 가동하면 집진실에 조밀한 간격으로 배치된 다수개의 집진판 사이의 좁은 공기통로로 공기가 통과할 때 유입구측의 필터에서 여과되지 못한 공기중에 부유된 미립자의 분진이 정전기를 띤 집진판에 근접되면서 분진의 전하를 띤 미립자는 정전기를 띤 집진판의 표면에 흡착되고 정화된 공기는 통체의 출구를 통하여 외부로 배출된다.That is, a dust collector plate having a ventilated dust collecting chamber equipped with a filter and a blower, an electrostatic electrode plate made of a synthetic resin material such as acrylic where static electricity is generated by friction, and the dust collecting plate are described above. It is arranged in the dust collection chamber in parallel at predetermined intervals, and is composed of a friction plate which causes static electricity by rotational friction by a rotational side driven by a motor in the space of the dust collecting plate. In addition, friction cloths such as a surface are attached to both surfaces of the friction plate so as to be interchangeable, so as to contact the inner surfaces of both sides of the dust collecting plate and generate static electricity on both surfaces of the dust collecting plate. If the blower is operated while driving the friction plate continuously, the air flows into the narrow air passage between the plurality of dust collecting plates arranged in the dust collecting chamber at the tightly spaced dust. The charged particles of dust near the dust collector are adsorbed on the surface of the electrostatic dust collector and the purified air is discharged to the outside through the outlet of the cylinder.

집진판에 흡착된 분진은 마찰판의 구동을 정지하여 정전기가 방전되어 흡착력이 소실(消失)되면 하방의 설합형 집진통으로 낙하되어 수집된다. 집진통에 수집된 분진은 설합처럼 꺼내어 소제한다.When the dust adsorbed on the dust collecting plate stops driving of the friction plate and the static electricity is discharged and the adsorption force is lost, the dust is dropped into the collecting dust collecting container below and collected. Dust collected in the dust collecting container is taken out and cleaned like a suture.

본 발명에서는 마찰면을 증대하기 위하여, 각 마찰판의 양측면과 마찰되도록 복수개의 정전극판이 마찰판의 양측에서 하나의 케이스 형태로 구성되어 있고 이 집진판은 조밀한 간격을 두고 통체의 집진실에 배치되므로서 분진의 전체적인 흡착면적을 증대할 수 있다.In the present invention, in order to increase the friction surface, a plurality of positive electrode plates are formed in one case form on both sides of the friction plate so as to be rubbed with both sides of each friction plate, and the dust collecting plates are arranged in the dust collecting chamber of the cylinder at close intervals. The overall adsorption area of dust can be increased.

마찰판은 그 집진판의 공간내부에 밀봉상태를 설치되어 있어, 마찰판에는 분진이 부착되지 않으며, 마찰에 의하여 면포의 섬유층이 마모되면 집진판의 일부를 개방하고 회전마찰판을 들어 내어 마찰판의 면 마찰포 등을 교체할 수 있게 되어 있다.The friction plate is provided in a sealed state in the space of the dust collecting plate, and dust is not attached to the friction plate. When the fiber layer of the cotton cloth is worn out by friction, part of the dust collecting plate is opened and the rotating friction plate is lifted to remove the surface friction cloth of the friction plate. It is possible to replace.

본 발명의 마찰 정전기 집진장치는 직류의 고전압을 전혀 사용하지 않으므로 전기 집진기에서 보는 대전(帶電)전극이나 방전(放電)전극 등이 없으며, 글로우 방전 이나 아크 방전에 의한 불꽃도 생기지 않으므로 흡착된 분진이 탄화되는 일도 없고 불꽃에 의한 화재의 발생 우려도 전혀 없다. 또 마찰판을 구동하는 정도의 작은 동력만으로 정전기 집진장치를 유효하게 가동할 수 있다.Since the tribostatic electrostatic precipitator of the present invention does not use a high voltage of direct current at all, there is no charging electrode or discharge electrode seen in the electric precipitator, and no spark is generated due to glow discharge or arc discharge. There is no carbonization and there is no fear of fire caused by the flame. In addition, the electrostatic precipitator can be effectively operated with only a small amount of power to drive the friction plate.

본 발명의 마찰 정전기 집진장치는 그 기능상, 가정, 사무실, 공중장소 등의 공기를 정화하는데 사용하기에 적합하다.The tribostatic electrostatic precipitator of the present invention is functionally suitable for use in purifying air in homes, offices, public places, and the like.

도1은 본 발명의 측단면도이고 도2는 본 발명의 평단면도이다.Figure 1 is a side cross-sectional view of the present invention and Figure 2 is a cross-sectional plan view of the present invention.

집진기(A)는 직사각형의 통체(B), 정전기 집진판(C), 정전기 발생용 회전 마찰판(D)으로 구성되어 있다.The dust collector A is composed of a rectangular cylinder B, an electrostatic dust collecting plate C, and a rotating friction plate D for generating static electricity.

통체(B)는 공기 유입구(i)측과 유출구(u)측에 통상의 필터(f)(f')및 송풍팬(F)이 구비되어 있고 송풍팬(F)에 의하여 통체(B)내부의 유입구(i)와 유출구(u)사이로 공기가 일방향으로 통풍하게 되어 있고 통체(B)의 양측 필터(f)(f')로 구획되는 중간 공간부는 집진실(G)로 되어 있다.The cylinder B is provided with the usual filter f (f ') and the blowing fan F at the air inlet i side and the outlet u side, and is inside the cylinder B by the blowing fan F. The air is ventilated in one direction between the inlets i and the outlets u, and the intermediate space portion partitioned by the two filters f (f ') of the cylinder B is a dust collecting chamber G.

정전기 집진판(C)은, 아크릴 등의 합성수지재질로서 복수개의 정전(靜電)극판 (p)으로 밀봉형 케이스로 되어 있고, 집진판(C)은 그 내부에 마찰판을 설치하기 위하여 상부체(Ca)와 하부체(Cb)로 구분되어 상부체를 하부체에 덮개처럼 분리결합하게 되어 있다. 집진판의 상부체(Ca)와 하부체(Cb)가 결합되는 중간부에 축 관통공(h)이 형성되어 마찰판의 회전축이 관통할 수 있게 되어 있다. 이 집진판은 상기 통체(B)의 중간 집진실(G)에 조밀한 간격의 병열로 적절한 고정수단(t)에 의하여 설치되어 있다. 실시에 있어서, 집진판 사이의 간격은 10-20mm 정도이다. 이 집진판의 설치간격은 가변적이다. 집진판의 내부 간격은 마찰판의 두께에 의하여 결정된다. 집진실(G)에 병열로 설치된 집진판(C)의 격리된 틈사이는 공기통로(c)가 되며 이 통로(c)를 공기가 통과할 때 분진의 전하 입자(d)가 정전기를 띤 집진판(C)의 표면에 흡착된다.The electrostatic dust collecting plate C is made of a synthetic resin material such as acrylic, and is formed in a sealed case with a plurality of electrostatic electrode plates p, and the dust collecting plate C is connected to the upper body Ca in order to install a friction plate therein. It is divided into a lower body (Cb) is to separate the upper body to the lower body as a cover. A shaft through hole h is formed at an intermediate portion where the upper body Ca and the lower body Cb of the dust collecting plate are coupled to each other so that the rotating shaft of the friction plate can pass therethrough. This dust collecting plate is provided in the intermediate dust collecting chamber G of the said cylinder B by the suitable fixing means t by the parallel space | interval of dense intervals. In practice, the distance between the dust collecting plates is about 10-20 mm. The installation interval of this dust collecting plate is variable. The internal spacing of the dust collecting plate is determined by the thickness of the friction plate. Between the isolated gaps of the dust collecting plate (C) installed in parallel in the dust collecting chamber (G) becomes an air passage (c), and when the air passes through the passage (c), the dust particles (d) of the dust is electrostatic dust collecting plate ( C) is adsorbed on the surface.

상기 정전극판과 마찰하여 정전기를 발생시키는 회전 마찰판(D)은 지름이 약 300-500mm 정도의 원판체로서 마찰판(D)의 양면에 면 마찰포(r)가 중심부에서 지름 방향으로 복수개조로 적합한 부착수단에 의하여 교체가능하게 부착되어 있고 사용중 마모되면 새것으로 교체사용된다. 면 마찰포(r)의 섬유길이는 집진판의 내면과 접찰 할 수 있는 여유 있는 길이로 되어 있다.The rotating friction plate (D), which generates static electricity by friction with the positive electrode plate, has a diameter of about 300-500 mm, and a surface friction cloth (r) suitable for both sides of the friction plate (D) in the radial direction from the center of the disk is about 300-500 mm in diameter. It is replaceably attached by means of attachment and if worn out during use, it is replaced with a new one. The fiber length of the surface friction cloth r is made into the allowable length which can contact with the inner surface of the dust collecting plate.

여러개의 마찰판(D)은 각각 상기 집진판(C)내부에 설치되며,이때 집진판(C)의 상부체(Ca)를 열고 마찰판(D)을 집진판(C)내부에 설치한 후에 다시 집진판의 상부체(Da)를 하부체(Cb)에 결합시키어 회전 마찰판(D)이 집진판(C)내부에 밀봉되게 하는 것이다. 집진판(C)내부에 설치된 마찰판(D)은 집진판(B)에 형성된 축 관통공(h)으로 관통된 하나의 회전축(s)에 지지되어 모터(m)로 구동되는 회전축(s)에 의하여 모든 마찰판(D)이 동시에 회전되어 각 집진판(C)의 내면인 정전극판 (p)과 마찰하게 되어 있다.A plurality of friction plates (D) are respectively installed inside the dust collecting plate (C), at which time the upper body (Ca) of the dust collecting plate (C) is opened and the friction plate (D) is installed inside the dust collecting plate (C), and then the upper body of the dust collecting plate (C) again. (Da) is coupled to the lower body (Cb) so that the rotary friction plate (D) is sealed in the dust collecting plate (C). The friction plate D installed inside the dust collecting plate C is supported by one rotation shaft s penetrated by the shaft through-hole h formed in the dust collecting plate B, and is driven by the rotation shaft s driven by the motor m. The friction plate D is simultaneously rotated to rub against the positive electrode plate p, which is an inner surface of each dust collecting plate C.

마찰판(D)을 지지한 회전축(s)은 상기 통체(B)에 적합한 축받이 등의 지지 수단(b)에 의하여 가로로 설치되어 감속기가 구비된 모터(m)에 의하여 구동된다. 마찰판(D)의 실제적인 회전속도는 2-5rps 정도의 저속도로 회전되며 집진상항에 따라 회전속도를 증감한다. 마찰판(D)은 집진판(C)의 양측 내면, 즉 정전극판(p)과 마찰된다. 이로 인하여 정전극판(p)을 겸하는 집진판(C)의 양측 표면에 음전하(電荷)로 대전(帶電)되어 집진실(G)의 공기통로(c)를 통과하는 공기중에 부유된 분진의 양전하(電荷) 미립자는 집진판(C)의 양면에 부착되어 공기를 정화하게 된 것이다.The rotating shaft s supporting the friction plate D is installed horizontally by a supporting means b such as a bearing suitable for the cylinder B, and is driven by a motor m provided with a speed reducer. The actual rotation speed of the friction plate (D) is rotated at a low speed of about 2-5rps and increase or decrease the rotation speed according to the dust collection conditions. The friction plate D is rubbed against both inner surfaces of the dust collecting plate C, that is, the positive electrode plate p. As a result, the positive charges of dust suspended in the air passing through the air passage c of the dust collecting chamber G are charged with negative charge on both surfaces of the dust collecting plate C, which also serves as the positive electrode plate p. ) Fine particles are attached to both surfaces of the dust collecting plate (C) to purify the air.

본 발명은 도면에 표시된 것에 의하여 설명되어 있으나 실시에 있어서 집진판의 밀봉수단은 상부체와 하부체의 분리수단에 한정하지 않고 집진판의 사방 주연부를 밀봉하는 수단을 채용할 수도 있다. 또 마찰판의 구동기구 및 전동기구는 설계적으로 가변할 수 있다.Although the present invention has been described by what is shown in the drawings, in the practice, the sealing means of the dust collecting plate is not limited to the separating means of the upper body and the lower body, and means for sealing the four peripheral edges of the dust collecting plate may be employed. In addition, the drive mechanism and the transmission mechanism of the friction plate can be varied in design.

본 발명은 직류의 고전압을 집진에 사용하지 않고 마찰 정전기에 의하여 집진하는 집진수단을 기술요지로 한다. 따라서 집진중에는 마찰판의 지속적인 구동이 필요하다. 또 구조적으로 밀봉형 집진판으로 구성한 것은 내부의 마찰판에 분진이 부착 오염되는 것을 방지하고 분진에 의한 정전극판과 마찰판과의 마찰작용에 장해 되는것을 방지하며 마찰면적을 증대하는데 유용하다.SUMMARY OF THE INVENTION The present invention is directed to a dust collecting means for collecting dust by friction static electricity without using a high voltage of direct current for dust collection. Therefore, during dust collection, continuous driving of the friction plate is necessary. In addition, the structurally sealed dust collecting plate is useful for preventing dust from adhering to the internal friction plate and preventing contamination by friction between the positive electrode plate and the friction plate, and increasing the friction area.

In this case, a quiet blowing is preferable, and the air introduced into the inlet (i) by the blower (F) is discharged through the air passage (c) between the respective dust collecting plates (C) of the dust collecting chamber (G) inside the cylinder (B). u) outflow. During the circulation of the air, several friction plates D driven by the motor m rub against the positive electrode plates p on the inner surface of each dust collecting plate C, so that static electricity is generated, and the friction plates D are charged with positive charge. Negative charge is charged on both surfaces of the dust collecting plate C, which is a denser and positive electrode plate. At this time, the dust in the air is primarily filtered by the filter (f), and the fine particles of the positive charge of the dust during the second passage through the narrow air passage (c) between the dust collecting plate (C) in the dust collecting chamber (G) Is adsorbed on both sides of the dust collecting plate (C) and the purified air from which the dust is separated is discharged to the outside through the filter (f ') of the outlet (u) side.

통체(B)의 하방측에는 설합형 집진통(g)이 형성되어 있어 마찰판의 구동이 정지되어 정전기가 모두 방전되면 집진판(C)에 부착된 분진은 하부측에 설치된 설합형 집진통(g)에 낙하 수집되므로 분진통을 꺼내어 분진을 간편하게 제거한다.In the lower side of the cylinder (B), a set-type dust collector (g) is formed. When the driving of the friction plate is stopped and all the static electricity is discharged, the dust attached to the dust collector (C) is placed in the set-type dust collector (g) installed on the lower side. As it is collected dropping, take out the dust container and remove dust easily.

집진기의 사용중 마찰판(D)의 면 마찰포(r)가 마모되면 집진판(C)의 상부체(Ca)를 열고 마찰판(D)에 면 마찰포(r)의 새것으로 교체하여 부착하여 반복적으로 사용한다.If the surface friction cloth (r) of the friction plate (D) is worn while the dust collector is in use, open the upper body (Ca) of the dust collection plate (C) and replace it with a new one of the surface friction cloth (r) on the friction plate (D) and repeatedly use it. do.

본 발명은 정전기 집진장치에 있어서, 집진판을 겸하는 정전극판과 마찰판과의 회전 마찰에 의하여 발생된 정전기를 이용하여 집진할 수 있게 구성하였기 때문에 다수개로 병열설치된 집진판의 넓은 집진면에 의하여 필터로 여과되기 어려운 미립자의 분진을 용이하게 흡착 분리하여 유효하게 공기를 정화 할 수 있다.In the electrostatic precipitator, the present invention is configured to collect dust using static electricity generated by rotational friction between a positive electrode plate serving as a dust collecting plate and a friction plate, so that the filter is filtered by a wide dust collecting surface of a plurality of parallel collecting dust collecting plates. Difficult to easily adsorb and separate the dust of difficult fine particles can effectively purify the air.

또 전기 집진기 처럼 수천내지 수만 볼트의 직류 고전압을 사용하지 않으므로 집진을 위한 코로나 방전 과정에서 아크방전이나 글로우 방전이 생기지 않어 집진판에 부착된 분진의 탄화현상이 없고 불꽃에 의한 화재의 위험이 없다.In addition, as it does not use DC high voltage of thousands to tens of thousands of volts like electric dust collector, there is no arc discharge or glow discharge in the corona discharge process for dust collection, so there is no carbonization of dust attached to the dust collector and there is no risk of fire by flame.

또 정전기를 이르키기 위한 마찰판의 구동에 소요되는 최소한의 동력으로 집진기를 가동할 수 있어 전기 에너지량을 절감할 수 있다.In addition, the dust collector can be operated with the minimum power required to drive the friction plate to prevent static electricity, thereby reducing the amount of electric energy.

또 집진판이 밀봉형 케이스로 되어 있어 그 내부에 설치된 마찰판이 밀봉상태로 유지되어 분진의 부착에 의한 오염이 방지되고 마찰작용에 장해를 받지 않는등의 이점이 있다.In addition, since the dust collecting plate is a sealed case, the friction plate installed therein is kept in a sealed state, thereby preventing contamination by adhesion of dust and being free from obstacles to friction.

또 구성이 간단하고 취급이 용이하여 가정이나 사무실, 공중 집회장소 등의 공기정화에 유용하게 사용할 수 있는 등의 여러가지 효과가 있다.In addition, since the configuration is simple and easy to handle, there are various effects such as being useful for air purification in homes, offices and public meeting places.
