Description

펄스정전분무장치{Pulse-induction spray-charging nozzle system.}Pulse-induction spray-charging nozzle system.

본 발명은 약액을 분무하는 노즐(nozzle)의 외측부분에 원통형 절연체를 부설하고 상기 원통형 절연체의 외측 적정위치에 정전유도전극을 설치하고, 이 정전유도전극에 소정의 펄스전압을 인가하여 노즐로부터 분무되는 약액입자들을 전기적으로 펄스정전 유도대전시켜 대상 작물의 잎의 앞면과 뒷면에 정전력에 의해 매우 효과적으로 약액이 부착되도록 한 펄스정전분무장치에 관한 것이다.According to the present invention, a cylindrical insulator is provided on an outer portion of a nozzle for spraying a chemical liquid, and an electrostatic induction electrode is installed at an appropriate position outside the cylindrical insulator, and a predetermined pulse voltage is applied to the electrostatic induction electrode to spray from the nozzle. The present invention relates to a pulse electrostatic spraying device in which the chemical liquid particles are electrically electrostatically induced by pulse electrostatic discharge, so that the chemical liquid is attached to the front and rear surfaces of the leaves of the target crop very effectively by electrostatic force.

통상의 정전분무장치는 수용성 약액이 분무되는 노즐의 외측부분에 부설된 원통형 절연체의 내측에 직류정전유도전극이 노출되게 설치되고, 이 직류정전유도전극에 직류고전압을 인가하는 구조로 구성으로 되어 있으며, 화분 등에 물을 주수하는 소형 분무장치에서부터 대량의 약액은 농작물이나 과수원에 분무, 방제하는 대형 분무장치에 이르기까지 여러 분야에 다양하게 사용될 수 있게 된다.Conventional electrostatic spraying device is installed so that the DC electrostatic induction electrode is exposed inside the cylindrical insulator attached to the outer portion of the nozzle to which the water-soluble chemical liquid is sprayed, and has a structure that applies a DC high voltage to the DC electrostatic induction electrode. For example, a small spray device for watering plants, pots, etc., and a large amount of chemical liquids can be used in various fields, ranging from large spray devices for spraying and controlling crops or orchards.

이와 같은 구성의 종래 정전분무장치는 도전성이 큰 통상의 수용성 약액을 분무하는 경우 원통형 절연체의 표면에 설치되는 직류정전유도전극과 접지된 약액 출구간에 고전압을 인가하면 수용성 약액 분무입자들이 표면에 부착되어 전기절연성을 크게 저감시키거나 단락시키게 된다. 따라서 인가 고전압이 증가하면 오히려 분무입자의 정전대전능력이 크게 저하되므로 분무입자의 부착효율이 크게 감소되는 문제점이 있다.In the conventional electrostatic spraying device having such a configuration, when spraying a conventional water-soluble chemical liquid having high conductivity, water-soluble chemical liquid spray particles are attached to the surface when a high voltage is applied between the DC electrostatic induction electrode installed on the surface of the cylindrical insulator and the grounded chemical liquid outlet. The electrical insulation is greatly reduced or shorted. Therefore, when the applied high voltage increases, the electrostatic charge capability of the spray particles is greatly reduced, so that the adhesion efficiency of the spray particles is greatly reduced.

한편, 농약살포에 사용되는 분무노즐은 특히 매우 방제효율이 높게 설계되어야 하지만 관성력과 점성력에 의존하기 때문에 그 효율에 근본적인 한계가 있다. 즉, 방제 분무입경이 적정 크기가 되고 또한 균일한 분사로 농작물에 골고루 부착되게 하여야 한다.On the other hand, the spray nozzles used for spraying pesticides have to be designed to have a particularly high control efficiency, but there is a fundamental limitation in the efficiency because they depend on inertial and viscous forces. That is, the control spray particle size should be appropriately sized and uniformly sprayed on the crops.

그러나 현행 실제 농약 방제작업 체계하에서의 약액살포는 원거리(3∼30m) 살포를 해야하며, 따라서 멀리까지 도달할 수 있게 분무입경이 매우 커야하기 때문에 균일살포가 되지 못하고 살포효율 또한 매우 낮아 비효과적인 문제점이 있다. 즉, 약액 살포시 입자가 큰 분무입자들이 유수, 침투 및 농작물에 이르기 전에 지면에 떨어지거나 작은 분무입자들이 바람에 의한 풍비산(風飛散)과 증발 등으로 인한 손실이 매우 큰 편이다.However, chemical spraying under the current actual pesticide control system should be sprayed at a long distance (3 ~ 30m). Therefore, the spray particle size should be very large so that it can reach far, so uniform spraying is not very effective and the spraying efficiency is very low. have. That is, when spraying chemical liquids, large particles of spray particles fall to the ground before flowing into the water, infiltration, and crops, or small spray particles have a great loss due to wind breakdown and wind evaporation.

그리고 무엇보다도 병충해가 집중 서식하는 농작물의 잎 뒷면에는 약액 부착효율이 극히 낮은 문제점이 있다. 즉, 통상의 분무장치의 경우 대상작물의 면적대비 농약 부착률은 20% 이하이며, 특히 잎의 뒷면은 5% 이하로 매우 낮고, 65%는 지면으로, 15%는 부유(drift) 또는 증발하여, 결국 80%이상이 환경오염원으로 작용하는 심각한 실정이다. 더욱 심각한 것은 현재의 농약분무장치의 실제 병충에 도달하는 살충구제비율은 0.01%정도로 추정되고 있다는 것이다.And above all, there is a problem that the adhesion efficiency of the chemical solution is extremely low on the leaf back of the crop in which the pests are concentrated. That is, in the case of a conventional spraying device, the pesticide adhesion rate to the area of the target crop is 20% or less, in particular, the back side of the leaf is very low, 5% or less, 65% to the ground, and 15% to drift or evaporate. In the end, more than 80% is a serious source of environmental pollution. More seriously, the pesticide control rate to reach the actual pests of current pesticide sprayers is estimated to be around 0.01%.

한편, 우리나라의 농약사용량은 80년도 중반에는 약 20만톤 정도이던 것이, 90년도 중반에는 40만톤 이상으로 크게 증가하였으며 2000년대 들어 골프장 등의 증가로 농약사용량이 더욱 증가하는 추세이므로 농경지나 하천의 농약오염문제가 크게 우려되고 있으나 이에 대한 기술적인 대책이 없는 상태이다.On the other hand, the amount of pesticides used in Korea was about 200,000 tons in the mid 80's, more than 400,000 tons in the mid 90's, and the use of pesticides in agricultural lands and rivers is increasing due to the increase of golf courses in 2000s. Contamination is a major concern, but there are no technical measures.

따라서 본 발명은 상기와 같은 문제점을 해결하기 위하여 통상의 분무노즐에 원통형 절연체를 부착하고, 이 원통형 절연체의 내측에 설치된 통상의 직류정전유도전극 대신에 원통형 절연체의 외측 적정위치에 펄스정전유도전극을 매립 설치하고, 상기 펄스정전유도전극에 통상의 직류고전압 대신 펄스고전압을 인가함으로써 누설전류를 근원적으로 차단할 뿐 아니라 낮은 전력으로 분무입자의 유도대전력(誘導帶電力)을 매우 효과적이고 고효율로 증가시킬 수 있는 펄스정전분무장치를 제공함에 목적이 있다.Therefore, in order to solve the problems described above, the present invention attaches a cylindrical insulator to a conventional spray nozzle, and instead of the normal DC electrostatic induction electrode installed inside the cylindrical insulator, a pulse capacitive induction electrode is placed at an appropriate position outside the cylindrical insulator. By buried and applying a pulsed high voltage to the pulsed electrostatic induction electrode instead of the normal DC high voltage, the leakage current is fundamentally blocked and the induced large power of the spray particles can be increased very effectively and efficiently with low power. An object of the present invention is to provide a pulse electrostatic spray device.

상기 목적을 달성하기 위하여 통상의 약액 분무노즐의 외측에 원통형 절연체를 부가 설치하고 상기 원통형 절연체의 외측 적정위치에 원통형 펄스정전유도전극을 매립 설치하고, 이 펄스정전유도전극에 파고전압(peak voltage)이 매우 높고 시비율(duty ratio)이 조절되는 펄스고전압(pulse high voltage)을 인가함으로써 노즐로부터 분무되는 약액이 펄스제어기법에 의해 정전유도대전되는 구조로 구성하도록 한다.In order to achieve the above object, a cylindrical insulator is additionally installed on the outer side of a conventional chemical liquid spray nozzle, and a cylindrical pulse electrostatic induction electrode is embedded in an appropriate position outside the cylindrical insulator, and the peak voltage is applied to the pulse electrostatic induction electrode. By applying a pulse high voltage having a very high and duty ratio, the chemical liquid sprayed from the nozzle is configured to have a structure in which electrostatic induction is charged by a pulse control technique.

여기서, 펄스정전유도전극은 원통형 절연체에 적절하게 매설하거나 비유전율이 매우 높고 절연성이 좋은 유전체를 사용함으로써 이곳에서의 전압저하가 최소로 되게 하거나, 원통형 절연체의 내측에 별도의 적정 내부 정전유도전극을 설치할 수도 있다.Here, the pulsed electrostatic induction electrode is appropriately embedded in the cylindrical insulator, or by using a dielectric having a very high dielectric constant and good dielectric property to minimize the voltage drop therein, or a separate appropriate internal electrostatic induction electrode inside the cylindrical insulator. You can also install.

이때 원통형 절연체는 비유전율(εr〉6), 절연저항율(ρ〉1016Ωm), 그리고 내아크성(耐arc性, E〉40kV/cm)이 크며, 흡습율(h〈0.01%/24hrs)이 적고, 아크방전시 탄화 도전로(carbonized conducting path)를 형성하지 않는 것이 좋은 재질이며, 이러한 특성의 재질을 사용하도록 함이 바람직하다.In this case, the cylindrical insulator has a high dielectric constant (ε r > 6), insulation resistivity (ρ> 10 16 Ωm), and arc resistance (E> 40 kV / cm), and a moisture absorption rate (h <0.01% / 24hrs). It is a good material to have a small number of) and does not form a carbonized conducting path during arc discharge, and it is preferable to use a material having such characteristics.

또한, 정전유도전극은 매우 얇은 금속제의 원통전극이나 세선(fine wire)이나 또는 세편대(fine strip)등으로 형성된 원통형 전극으로 매립하여 구성하거나, 또는 도전성도료 (paint 또는 paste 등)를 적정형상으로 도포하고 적정 절연체로 피복하여 사용할 수도 있다.In addition, the electrostatic induction electrode may be formed by embedding a very thin metal cylindrical electrode, a cylindrical electrode formed of fine wire, or a fine strip, or a conductive paint (such as paint or paste) in an appropriate shape. It can also be applied and coated with a suitable insulator.

이와 같은 통상의 구조의 정전대전장치는 공기를 매개로 한 정전유도전극과 노즐분사구 끝과의 저항부하 형태이나, 본 발명과 같은 매립형 전극구조의 경우는 저항부하가 아닌 매몰된 정전유도전극과 절연박층과 그리고 노즐분사구 끝의 약액 분무주간(噴霧柱間)와의 공기층이 정전용량부하가 되며 이러한 회로에서 적절한 펄스고전압을 인가하면 대부분의 펄스전압이 공기층의 정전용량에 인가되게 되는 구조이므로 연면상의 누설전류는 거의 없어진다.The electrostatic charging device having such a conventional structure has a resistance load form between the air-induced electrostatic induction electrode and the tip of the nozzle injection nozzle, but in the case of the buried electrode structure according to the present invention, the buried electrostatic induction electrode is not insulated from the buried electrostatic induction electrode. The air layer between the thin layer and the chemical spraying cycle at the end of the nozzle nozzle becomes the capacitive load, and if the appropriate pulse high voltage is applied in such a circuit, most of the pulse voltage is applied to the capacitance of the air layer. The current almost disappears.

또한, 펄스전압을 인가함으로써 펄스전압 특성상 직류전압에 비해 더 높은 파고전압(peak voltage)을 인가할 수 있을 뿐만 아니라 펄스 시비율(duty ratio)를 제어 및 조절함으로써 높은 대전효율에서도 소비전력은 저감시킬 수 있는 장점도 아울러 갖고 있다.In addition, by applying a pulse voltage, it is possible to apply a higher peak voltage than a DC voltage due to the characteristics of the pulse voltage, and to control and adjust the pulse duty ratio to reduce power consumption even at high charging efficiency. It also has advantages.

또한, 본 발명의 펄스전압 인가형 정전유도 대전 분무장치는 처리분무량을 증가 또는 작게 하기 위하여 규격을 크게 또는 작게 할 수도 있고 동일한 규격과 형상이라도 여러 개를 직렬이나 병렬 또는 직ㆍ병렬 혼합형으로 간편하게 구성하여 사용할 수도 있다.In addition, the pulse voltage application type electrostatic induction spray device of the present invention may be made larger or smaller in order to increase or decrease the amount of spray sprayed, and may easily be configured in series, parallel, or parallel / parallel mixed type even in the same standard and shape. It can also be used.

이하 본 발명의 바람직한 실시 예를 첨부도면에 따라 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

통상의 정전분무장치(가)는 도 1에 도시한 바와 같이 접지된 약액주입구(9)로부터 주입된 약액이 약액분사구(2)로부터 분사되어 나올 때 고전압이 인가된 직류정전유도전극(4)에 의해 분무약 액주(6)의 끝부분에서 분무입자들이 분리될 때 정전유도되어 분무입자(5)가 대전되게 된다.As shown in FIG. 1, a conventional electrostatic spraying device (A) is applied to a DC electrostatic induction electrode 4 to which a high voltage is applied when a chemical liquid injected from a grounded chemical liquid injection port 9 is ejected from the chemical liquid injection port 2. By the electrostatic induction when the spray particles are separated at the end of the spray liquid liquor 6, the spray particles 5 are charged.

상기와 같은 구조의 약액분사구(2)로부터 분사되는 분무입자(5)가 직접 직류정전유도전극(4)에 노출되고 약액분사구(2)와 직류정전유도전극(4)이 가능하면 서로 근접해 있어야만 분사약액이 효과적으로 유도대전 된다. 따라서 분무입자(5)가많은 대전량을 갖게 하기 위해서는 높은 직류고전압의 인가가 요구된다.The spray particles 5 sprayed from the chemical liquid injection hole 2 having the above structure are directly exposed to the direct current electrostatic induction electrode 4, and the chemical liquid injection port 2 and the direct current electrostatic induction electrode 4 should be injected as close as possible to each other. The chemical is effectively induced charged. Therefore, in order to make the spray particles 5 have a large charge amount, application of high DC high voltage is required.

그러나, 약액분사구(2)로부터 직류정전유도전극(4)이 근접하고 직류고전압이 인가된 직류정전유도전극(4)과 접지된 약액분사구(2) 간의 연면거리(surface distance)가 짧아지면 약액분사구(2)와 직류정전유도전극(4) 간에 전혀 불필요한 누설전류(leakage current)가 연면(沿面)을 따라 많게 흐르게 되어 대전효율이 크게 떨어진다.However, if the DC electrostatic induction electrode 4 is close from the chemical liquid injection port 2 and the surface distance between the DC electrostatic induction electrode 4 to which the DC high voltage is applied and the grounded chemical liquid injection port 2 is shortened, the chemical liquid injection port is shortened. Leakage current, which is completely unnecessary between (2) and the DC electrostatic induction electrode 4, flows along the creepage so that the charging efficiency is greatly reduced.

뿐만 아니라 약액분사구(2)로부터 분사된 미세 분무입자가 원통형절연체(3)의 내면상에 붙게 되고 약액분사구(2)와 직류정전유도전극(4)간의 연면거리간에도 전기저항이 매우 적은 수용성 약액이 붙게 되어 누설전류가 대폭 증가하므로 직류전원의 출력전압 즉 인가전압이 크게 감소(1/2∼1/8)하여 결국 분무의 정전대전력이 근원적으로 대폭 감소하게 되며 고전압 전원의 단락이나 손상의 원인이 되기도 한다.In addition, the fine spray particles sprayed from the chemical liquid injection hole (2) is attached to the inner surface of the cylindrical insulator (3), and the water-soluble chemical liquid with a very low electrical resistance even between the creepage distance between the chemical liquid injection hole (2) and the DC electrostatic induction electrode (4) As the leakage current increases greatly, the output voltage of DC power, that is, the applied voltage, is greatly reduced (1/2 to 1/8), and the electrostatic charge power of the spray is greatly reduced, which causes a short circuit or damage of high voltage power. It can also be.

따라서, 통상의 정전분무장치(가)는 약액분사구(2)의 주변에 반송공기분사구 (7)을 부설하여 반송공기주입구(10)로 건조한 반송공기를 주입함으로서 약액분사구(2)와 직류정전유도전극(4) 사이에 형성되는 연면거리가 공기격벽(空氣隔壁)에 의해 차단되어 절연을 유지하여 누설전류를 줄이게 되며, 또한 가능하면 이 건조반송공기로써 원통형절연체(3)의 내부의 분사약액 입자들을 외측출구로 강제 송출시킴으로써 원통형절연체 (3)의 내측으로 분무부착을 줄이는 방법을 사용하고 있다.Therefore, the normal electrostatic spraying device (A) installs the conveying air injection port 7 around the chemical liquid injection port 2 and injects dry conveying air into the conveying air inlet 10 to induce the chemical liquid injection port 2 and the DC electrostatic induction. The creepage distance formed between the electrodes 4 is blocked by the air partition to maintain insulation to reduce the leakage current, and if possible, the injection chemical particles inside the cylindrical insulator 3 with this dry conveying air. A method of reducing spray adhesion to the inside of the cylindrical insulator 3 is used by forcibly discharging them to the outside outlet.

이와 같은 경우, 추가로 반송공기 송출용 펌프가 별도로 필요하므로 장치의 제조원가가 상승하며 노즐(1)의 구조 또한 복잡해지는 문제점이 있다.In such a case, there is a problem in that a pump for conveying air is additionally required, so that the manufacturing cost of the apparatus is increased and the structure of the nozzle 1 is also complicated.

도 2는 본 발명 펄스분무장치(나)의 단면 구성도로, 상기와 같은 종래 정전분무장치(가)의 원통형절연체(3) 내측에 부설된 직류정전유도전극(4)을 원통형절연체(3)의 일단에 펄스정전유도전극(14)과 같이 매립 설치함으로써 약액분사구(2)와 펄스정전유도전극(14)간의 연면거리를 근원적으로 크게 할 뿐만 아니라 약액이 분사될 때 미세 분사약액이 원통형절연체(3)의 내면에 부착되더라도 매립 설치된 펄스정전유도전극(14)간의 연면상의 누설전류는 근원적으로 차단되게 된다.Figure 2 is a cross-sectional configuration of the pulse spraying device (b) of the present invention, the DC electrostatic induction electrode (4) installed inside the cylindrical insulator (3) of the conventional electrostatic spraying device (a) as described above of the cylindrical insulator (3) By embedding at one end together with the pulsed electrostatic induction electrode 14, the creepage distance between the chemical liquid injection sphere 2 and the pulsed electrostatic induction electrode 14 is not only largely enlarged, but also when the chemical liquid is injected, the fine sprayed chemical liquid is a cylindrical insulator (3). Even if attached to the inner surface of the c), leakage currents on the creepage between the embedded pulse capacitive induction electrodes 14 are fundamentally blocked.

그러나 이와 같은 구성의 본 발명 펄스정전분무장치(나)는 도 3에 도시한 직류고전압(다)을 인가하는 경우 절연박층(13)에 대부분의 직류전압이 인가되어 분무입자(5)는 거의 정전대전되지 않게 된다. 따라서, 펄스고전압인가단자(18)에 도 4와 같은 펄스전압(라)을 인가하게 되면 대부분의 펄스전압은 분무약 액주(6)에 인가되므로 분무입자(5)가 효과적으로 정전유도 대전되게 된다.However, in the pulse electrostatic spray device (B) of the present invention having such a configuration, when the DC high voltage (C) shown in FIG. 3 is applied, most DC voltages are applied to the insulating thin layer 13, and the spray particles 5 are almost electrostatically discharged. It will not be charged. Therefore, when the pulse voltage D as shown in FIG. 4 is applied to the pulse high voltage applying terminal 18, most of the pulse voltage is applied to the spray liquid liquor 6, so that the spray particles 5 are effectively charged with electrostatic oil.

이 원리를 전기회로적으로 좀더 구체적으로 설명하면 다음과 같다.This principle is described in more detail as an electric circuit as follows.

즉, 통상의 정전분무장치(가)는 도 5와 같이 전기적 등가회로(마)로 나타낼 수 있으며, 도 3과 같은 직류전압(다)를 인가하는 경우 분무약 액주(6)와 펄스정전유도전극(14)의 대항외면 간의 공기정전용량(Ca)으로는 전류가 흐르지 않고 누설저항(Ra)으로만 전류가 흐르게 되어 누설전류가 문제되는 구조이다.That is, the conventional electrostatic spraying device (A) may be represented by an electrical equivalent circuit (E) as shown in FIG. 5, and when the DC voltage (C) as shown in FIG. 3 is applied, the sprayed liquid liquor 6 and the pulse electrostatic induction electrode in air the capacitance (C a) between the outer surface of the counter 14 is a structure in which the current is a current that flows a leakage current problem only by the leakage resistance (R a) does not flow.

한편, 도 2와 같은 구성의 본 발명의 펄스정전분무장치(나)의 경우, 도 3과 같은 직류전압(다)를 인가하면 저항성부하(抵抗性負荷)이므로 절연박층(13)의 체적정전용량(Cd)과 분무약 액주(6)와 펄스정전유도전극(PE)(14)의 대항외면간의 공기정전용량(Ca)으로는 전류가 흐르지 않고, 절연박층(13)의 체적저항(Rd)이 누설저항 (Ra)에 비해 매우 크기 때문에 분무입자(5)는 거의 대전되지 않게 되나, 도 4와 같은 펄스전압(라)를 인가하면 용량성부하(容量性負荷)가 되어 절연박층(13)의 체적저항(Rd)이 매우 크게 되고 절연박층(13)의 체적정전용량(Cd)에 비해 분무약 액주(6)와 펄스정전유도전극(PE)(14)간의 공기정전용량(Ca)가 매우 작게 되어 분무약 액주(6)와 펄스정전유도전극(PE)(14)의 대항외면 사이에 형성되는 공기정전용량 (Ca)에 대부분의 전압(실제 실험결과 90∼98%정도)이 인가되게 되므로 효과적으로 분무입자(5)를 정전유도대전할 수 있게 되며, 이 때 누설전류는 도 1과 같은 통상의 정전분무장치(가)에 비해 크게 줄일 수 있게 된다(실제실험결과 1∼5%정도).On the other hand, in the case of the pulse electrostatic spraying device (B) of the present invention having the configuration as shown in Fig. 2, when the direct current voltage (C) as shown in Fig. 3 is applied, it is a resistive load, so that the volumetric capacitance of the insulating thin layer 13 No current flows through the air capacitance C a between (C d ) and the opposing outer surface of the spray liquid liquor 6 and the pulsed electrostatic induction electrode (PE) 14, and the volume resistance R of the insulating thin layer 13 d ) is much larger than the leakage resistance (R a ), so that the spray particles (5) are hardly charged. However, when the pulse voltage (D) as shown in FIG. 4 is applied, the sprayed particles (5) become capacitive loads. The volume resistance R d of (13) becomes very large and the air capacitance between the spray liquid liquor 6 and the pulse electrostatic induction electrode PE 14 is larger than the volume capacitance C d of the insulating thin layer 13. (C a) is very small, the spray liquid column of about 6 and the pulse electrostatic induction electrode (PE) (14) air-capacitance (C a) most of the voltage (actual experiment is formed between the outer surface of the counter And 90 to 98%) is effectively applied to the electrostatic induction charging of the spray particles (5), the leakage current can be significantly reduced compared to the conventional electrostatic spraying device (a) as shown in FIG. (1-5% of actual test results).

이때 가능하면 절연박층(絶緣薄層)(13)은 절연파괴가 되지 않는 0.01∼1mm 두께로 가능하면 얇게 형성하는 것이 좋으며, 여러 가지 적절한 전극매설방법이 적용될 수 있다. 즉, 금속제 전극상에 얇은 고전압 절연체를 피복 또는 도포하거나 경우에 따라서는 얇은 고전압 절연체의 뒷면에 적정의 전극을 형성하여 원통형절연체(3)의 내면의 적정위치 즉, 직류정전유도전극(4)의 위치에 부착시켜 사용할 수도 있을 것이다.In this case, the insulating thin layer 13 may be formed as thin as possible with a thickness of 0.01 to 1 mm that does not cause breakdown, and various suitable electrode embedding methods may be applied. That is, by coating or applying a thin high voltage insulator on a metal electrode, or in some cases, by forming an appropriate electrode on the back of the thin high voltage insulator, the appropriate position of the inner surface of the cylindrical insulator 3, that is, the DC electrostatic induction electrode 4 It can also be used in place.

이때 사용되는 펄스정전유도전극(14)은 매우 얇은 금속제 원통전극이나 세선(fine wire)이나 또는 세편대(fine strip)등으로 형성된 원통형 전극으로 구성하거나, 또는 도전성도료(conducting paint 또는 paste 등)를 적절한 형상으로 도포하여 사용할 수도 있다.The pulsed electrostatic induction electrode 14 used here is composed of a very thin cylindrical electrode made of metal, a cylindrical electrode formed of a fine wire or a fine strip, or a conductive paint (conducting paint or paste, etc.). You may apply | coat and use in a suitable shape.

또한, 본 발명 펄스정전분무장치(나)의 구조에 도 4와 같은 펄스전압(라)를 인가하는 경우 실제로 분무약 액주(6)와 펄스정전유도전극(14)간에는 펄스전압의 절연파괴 특성상 직류전압 또는 평균전압(Vdc 또는 Vrms)에 비해 높은 파고전압 Vp(Vp=1.5∼2.4Vdc)를 인가할 수 있어서 유도대전량은 1.5∼2.4배로 크게 증가시킬수 있으면서도 시비율(tO/tT), 즉 전압작동시간(to)와 전압휴지시간(tF)을 적절히 조절함으로써 평균 소비전력을 40%∼70%로 크게 절감시킬 수 있게 된다.In addition, when the pulse voltage d as shown in FIG. 4 is applied to the structure of the pulse electrostatic spraying device (b) of the present invention, the direct current of the sprayed liquid liquor 6 and the pulse electrostatic induction electrode 14 is due to the dielectric breakdown characteristics of the pulse voltage. A higher crest voltage V p (V p = 1.5 to 2.4 Vdc) can be applied compared to the voltage or the average voltage (Vdc or V rms ) so that the induced charge can be increased 1.5-2.4 times while the application rate (t O / t T ), that is, by appropriately adjusting the voltage operating time (t o ) and the voltage stop time (t F ), it is possible to greatly reduce the average power consumption from 40% to 70%.

도 7은 본 발명 펄스정전분무장치(나)에 적용할 수 있는 펄스전원회로의 일 실시 예를 도시한 것으로, 적정 신호파형이 발생하는 트리거회로(TC)로 반도체 스윗칭소자(SS)를 스위칭시킴으로써 도 8과 같은 구형파 펄스저전압(Ps)을 얻은 다음 고전압승압트랜스(HT)에 인가하여 맥류형 펄스고전압(Pp)을 얻을 수 있도록 한다.FIG. 7 illustrates an embodiment of a pulse power supply circuit applicable to the pulse electrostatic spraying device (b) of the present invention. The semiconductor switching element SS is switched to a trigger circuit TC for generating an appropriate signal waveform. In this way, the square wave pulse low voltage Ps as shown in FIG. 8 is obtained, and then applied to the high voltage step-up transformer HT to obtain a pulse wave type pulse high voltage Pp.

도 8은 고전압펄스트랜스(HT)의 입력전압파형이고, 도 9는 고전압펄스트랜스 (HT)의 출력전압파형을 도시한 것이다.8 illustrates an input voltage waveform of the high voltage pulse transformer HT, and FIG. 9 illustrates an output voltage waveform of the high voltage pulse transformer HT.

한편, 본 발명에서 분무약 액주(6)와 펄스정전유도전극(14)간에는 가능한 높은 전압이 인가되는 것이 유도대전상 효과적이며, 또한 전압작동시간(tO)과 전압휴지시간(tF)을 조절하여 고주파로 반복시키는 것도 효과적이다.On the other hand, that the present invention is a high voltage potential between about liquid column 6 and the pulse electrostatic induction electrode 14 is spray applied in a phase induction charged effectively, and the voltage operation time (t O) and voltage rest period (t F) It is also effective to repeat the control at high frequency.

실험결과 한 주기시간(tT=tO+tF)이 10-6∼10-2초 범위내에서 효과적이었으나, 이는 본 발명의 펄스정전분무장치(나)의 용도나 크기, 분무량이나 적용분야, 필요효율 등에 따라 적정한 값으로 설정하여 사용할 수 있으나, 실제 실험결과 최적조건은 한 주기시간(tT)의 경우 2 x 10-5∼10-3초, 전압작동시간(tO)의 경우 10-6∼10-4초 범위, 그리고 시비율(tO/tT)은 5%∼60%에서 매우 효과적이었다.Experimental results showed that one cycle time (t T = t O + t F ) was effective within the range of 10 -6 to 10 -2 seconds, but this is the use, size, spray amount or application field of the pulse electrostatic spraying device (B) of the present invention. Although it can be set to an appropriate value according to the required efficiency, etc., the optimum condition of actual experiment results is 2 x 10 -5 to 10 -3 seconds for one cycle time (t T ) and 10 for voltage operation time (t O ). The range of -6 to 10 -4 seconds and the application rate (t O / t T ) were very effective at 5% to 60%.

한편, 절연박층(13)의 내측표면에 추가의 적정규격과 형상의 전압이 인가되지 않는 전극(dummy electrode)인 가전극(24)를 설정함으로써 도 6과 같이 본 발명 펄스정전분무장치(나)의 전기적 등가회로(바)의 절연박층 체적정전용량(Cd)과 분무약 액주(6)와 펄스정전유도전극간의 공기정전용량(Ca) 값을 구체적으로 확정시켜서 분무약 액주(6)와 펄스정전유도전극(14)간은 물론 펄스정전유도전극(14)와 가전극 (24)간의 펄스전압을 안정적으로 인가 되게 함은 물론 더욱 효과적인 정전분무장치가 된다.On the other hand, the pulse electrostatic spraying device of the present invention as shown in Fig. 6 by setting the provisional electrode 24, which is a dummy electrode, to which an additional proper specification and shape voltage is not applied to the inner surface of the insulating thin layer 13 (b). The sprayed liquid liquor 6 and the pulsed electrostatic capacity are determined by specifically determining the insulating thin layer volumetric capacitance Cd and the air capacitance 6 and the electrostatic capacitance Ca between the pulsed electrostatic induction electrode The pulse voltage between the induction electrode 14 as well as the pulse capacitive induction electrode 14 and the provisional electrode 24 can be stably applied as well as a more effective electrostatic spraying device.

실험결과에 의하면 적정크기의 가전극(24)를 부착시킴으로써 정전대전량이 10%∼25% 증가되는 것을 확인하였다. 이때 가전극(24)의 폭은 대개 펄스정전유도전극(14)과 동일하게 하는 것이 좋으나, 용도나 효율 적용형편에 따라 1/3∼3배 정도로 가변할 수도 있다.According to the test results, it was confirmed that the amount of electrostatic charge increased by 10% to 25% by attaching the provisionally sized electrode 24. In this case, the width of the provisional electrode 24 is generally the same as that of the pulse capacitive induction electrode 14, but may vary as much as 1/3 to 3 times depending on the application or efficiency application.

그리고, 펄스정전유도전극(14)의 외측에 매립 설치된 원통형 전극인 입자집속전극(29)을 추가 설치함으로써 약액분사구(2)로부터 분사된 분무입자(5)들이 입자집속전극(29)에 의해 전기적으로 반발(Coulomb 斥力)되어 중심축쪽으로 집속시킬 수 있게 하는 작용을 부과할 수 있게 되며, 이 결과 미세 분무입자들이 입자집속전극(29)에 의한 정전척력에 반발되어 중심축으로 이동하게 되어 원통형절연체(3)의 내면에 부착되지 않고 방출되게 되어 효율을 더욱 높이는 장점을 갖게 된다.Further, by installing the particle focusing electrode 29, which is a cylindrical electrode embedded in the outer side of the pulse electrostatic induction electrode 14, the spray particles (5) injected from the chemical liquid injection port (2) is electrically connected by the particle focusing electrode (29) It is possible to impose an action to recoil and focus toward the central axis. As a result, fine spray particles are repelled by the electrostatic repulsion by the particle focusing electrode 29 to move to the central axis. It is released without being attached to the inner surface of (3) has the advantage of further increasing the efficiency.

입자집속전극(29)에 전압을 인가하는 집속전극단자(19)는 접지단자에 연결하여 사용해도 되나, 분사입자를 더욱 고밀도로 집속하기 위해서는 별도의 적정형태의 고전압으로 제어하거나 또는 바이어스 전압으로 인가할 수도 있으며, 이는 TV 수상기의 전자편향원리(편향회로)와 동일하거나 비슷하므로 구체적인 설명은 생략한다.The focusing electrode terminal 19 for applying a voltage to the particle focusing electrode 29 may be connected to the ground terminal. However, in order to focus the sprayed particles more densely, the focusing electrode terminal 19 may be controlled with a high voltage of a suitable type or applied with a bias voltage. This may be the same as or similar to the electronic deflection principle (deflection circuit) of the TV receiver, so a detailed description thereof will be omitted.

또한, 본 발명의 펄스정전분무장치(나)에는 고속으로 분무입자(5)가 분사되어 나갈 때 원통형절연체(3)의 내측공간의 공기도 분무입자(5)에 충돌되어 분무입자(5)과 같이 분출되어야 하나 추가공기의 진입이 없어 원통형절연체(3)의 내측공간에 입경이 매우 작은 분무는 유체역학상 회전운동을 하면서 잔류하게되어 내측벽에 부착되어 누설전류를 증대시키거나 또는 분무입자(5)의 분사 방출을 유체역학적으로 방해하게 된다.In addition, in the pulse electrostatic spraying device (b) of the present invention, when the spray particles 5 are sprayed out at high speed, the air in the inner space of the cylindrical insulator 3 also collides with the spray particles 5, Although sprayed together, there is no entry of additional air, and the spray having a very small particle diameter in the inner space of the cylindrical insulator 3 remains during the hydrodynamic rotational movement and is attached to the inner wall to increase leakage current or spray particles ( The jet release of 5) is hydrodynamically impeded.

따라서 대류공기유입구(17)를 설치하면, 분무입자(5)의 고속분사시 분무입자 (5)의 주변의 공기도 분무입자(5)와 같이 동반 방사되어 내측공간의 압력이 낮아지고 노즐(1)의 외측 건조공기가 대류공기유입구(17)를 통해 유체역학적 압력차이로 자동자력으로 원통형절연체(3)의 내측공간으로 유입되므로 분무입자(5)가 원활하고 효과적으로 분사 방출되게 되고 내벽에의 미세분무입자의 부착도 줄어들게 되는 장점을 갖게 된다.Therefore, when the convection air inlet 17 is installed, the air around the spray particles 5 is also co-radiated together with the spray particles 5 during the high-speed spraying of the spray particles 5, so that the pressure in the inner space is lowered and the nozzle 1 ), The outside dry air flows into the inner space of the cylindrical insulator (3) automatically with the hydrodynamic pressure difference through the convection air inlet (17), so that the spray particles (5) can be sprayed smoothly and effectively, and fine to the inner wall The adhesion of spray particles is also reduced.

도 10은 종래 정전분무장치(가)와 본 발명 펄스정전분무장치(나)의 동일 조건하에서 실험한 입자 대전성능을 비교한 그래프로, 보는 바와 같이 본 발명의 펄스정전분무장치(나)는 종래의 직류정전분무장치(가)에 비하여 수배의 큰 유도대전량을 얻을 수 있음을 확인하였다.10 is a graph comparing particle charging performances tested under the same conditions of the conventional electrostatic spraying device (A) and the pulse electrostatic spraying device (B) of the present invention. As shown, the pulsed electrostatic spraying device (B) of the present invention is conventionally It was confirmed that a large amount of induced charges can be obtained several times as compared with DC electrostatic spraying apparatus of.

또한, 본 발명의 펄스정전분무장치(나)를 이용하는 경우 통상의 약액살포용 분무장치에 비해 농작물의 약액부착 비율이 2∼4배로 높고, 잎 뒷면의 부착비율은 3∼6배로 매우 높아져서 농약살포량이 1/2∼1/4로 대폭 감소되므로 충분한 방제 및 구충효과를 가지게 된다. 아울러, 토양오염이나 수질오염도 크게 줄일 수 있어서 경제적이고 환경오염방지가 가능하다.In addition, when using the pulse electrostatic spraying device (b) of the present invention, the chemical liquid adhesion rate of the crop is 2 to 4 times higher than that of the conventional chemical liquid spraying device, and the adhesion ratio of the leaf backside is very high to 3 to 6 times. Since it is greatly reduced to 1/2 to 1/4, it will have sufficient control and antiparasitic effect. In addition, soil pollution and water pollution can be greatly reduced, thereby enabling economic and environmental pollution prevention.

이와 같이 새롭게 고안된 본 발명의 펄스정전분무장치(나)는 분무노즐에 부착된 원통형 절연체의 외측에 매몰하여 부설함으로써 누설전류를 근원적으로 차단하여 분무입자의 대전효율을 상승시킬 수 있으며, 통상의 직류전압 대신에 펄스전압을 사용할 수 있어서 직류전압에 비해 매우 높은 파고전압을 인가할 수 있을 뿐만 아니라, 펄스 시비율을 제어 조절함으로써 소모전력까지 최소화할 수 있는 효과가 있다. 왜냐하면 통상의 대부분의 정전분무장치의 경우 휴대용 전원을 사용하기 때문에 소모전력의 최소화는 경제적으로 매우 중요하기 때문이다.The newly designed pulse electrostatic spraying device (b) of the present invention is buried outside the cylindrical insulator attached to the spray nozzle and laid thereon, thereby blocking the leakage current to increase the charging efficiency of the spray particles. The pulse voltage can be used instead of the voltage, so that a very high crest voltage can be applied as compared to the DC voltage, and the power consumption can be minimized by controlling and adjusting the pulse rate. Because most of the electrostatic spray device uses a portable power source because the minimization of power consumption is very important economically.

또한, 매립 설치된 정전유도전극의 내측에 적정 가전극을 설치함으로써 안정된 용량성 부하를 형성시켜 분무입자의 정전유도대전량을 더욱 높일 수 있으며, 접지 또는 제어전압을 인가할 수 있는 입자집속전극을 부가 설치함으로써 분사입자를 더욱 효율적으로 집속하여 방출하게 할 수 있는 효과가 있다.In addition, by installing an appropriate provisional electrode inside the buried electrostatic induction electrode, a stable capacitive load can be formed to further increase the electrostatic inductive charge amount of the spray particles, and a particle focusing electrode capable of applying ground or control voltage is added. By installing it, there is an effect that the sprayed particles can be focused and discharged more efficiently.

또한, 매립 설치된 펄스정전유도전극에 직류고전압 대신에 펄스고전압을 인가하게 하면 펄스전압 특성상 직류전압보다 매우 높은 파고전압을 정전유도전극에 인가할 수 있게 되어 약액입자의 정전대전력을 더욱 크게 증가시킬 수 있는 효과가 있다.In addition, if a pulse high voltage is applied to a buried pulse electrostatic induction electrode instead of a DC high voltage, a crest voltage that is much higher than the DC voltage can be applied to the electrostatic induction electrode due to the characteristics of the pulse voltage, thereby greatly increasing the electrostatic charge power of the chemical particles. It can be effective.

이상의 본 발명 펄스정전분무장치는 통상의 분무장치가 적용되는 모든 분야에 효과적으로 사용될 수 있다. 즉, 소용량의 화훼재배용에서부터 대용량의 기계적 및 자동적 정전분무장치로서는 물론 정전도장이나 정전분사등 분무입자를 대전시켜 분무부착시키는 다양한 분야와 용도로 매우 효과적으로 사용 및 적용할 수 있다.The pulse electrostatic spraying device of the present invention can be effectively used in all fields to which a conventional spraying device is applied. That is, it can be very effectively used and applied to various fields and applications for charging and spraying spray particles such as electrostatic coating or electrostatic spraying, as well as small-capacity flower cultivation to large-capacity mechanical and automatic electrostatic spraying devices.

또한, 본 발명의 펄스정전분무장치는 종래의 직류정전분무장치에 비해 수배의 큰 유도대전량을 얻을 수 있어서 농작물의 약액부착 비율이 2∼4배로 높으며, 잎의 뒷면에의 부착비율은 3∼6배로 매우 높아져서 농약살포량을 1/2∼1/4로 대폭 감소시킬 수 있을 뿐만 아니라 충분한 방제구충효과도 가지면서 토양이나 수질오염도 크게 줄일 수 있으므로 경제적일 뿐 아니라 환경오염이 방지되는 등의 효과가 있는 매우 유용한 발명이다.In addition, the pulse electrostatic spraying device of the present invention can obtain a large amount of induced charge compared to the conventional DC electrostatic spraying device, the chemical liquid adhesion rate of the crop is 2 to 4 times higher, and the adhesion ratio to the back of the leaf is 3 to 4 times. It is very high 6 times, which can greatly reduce the pesticide spraying amount from 1/2 to 1/4, and also has sufficient control insect repellent effect and greatly reduces soil and water pollution, so it is economical and prevents environmental pollution. That is a very useful invention.
