본 발명은 수산화칼륨수용액에 유황분말을 녹여서 수산화칼륨 성분이 혼합된 유황수용액을 제조하고 물에 희석시켜 해충방제에 사용하게 함으로써, 해충을 방제와 더불어 식물에 칼륨성분도 공급할 수 있도록 한 해충방제용 유황수용액 제조방법에 관한 것인바 더욱 구체적으로는, 해충 방제에 적합한 일정농도의 유황성분을 함유하는 유황수용액을 제조하기 위해 먼저 수산화칼륨수용액을 준비하고, 상기 수산화칼륨수용액에 일정비율의 유황분말을 안전하게 투입하면서 교반하는 방법으로 녹여서 수산화칼륨수용액이 혼합된 유황수용액을 제조하고 2000배의 물에 희석시켜서 엽면 살포할 수 있게 함으로써, 일정농도의 유황성분을 유지하면서 칼륨성분도 포함하는 해충 방제용 유황수용액을 제조하는 것이다.
The present invention relates to a sulfur-containing sulfuric acid solution which is prepared by dissolving sulfur powder in an aqueous solution of potassium hydroxide to prepare an aqueous sulfuric acid solution in which a potassium hydroxide component is mixed and diluting it with water to be used for controlling insects, More specifically, in order to prepare a sulfuric acid aqueous solution containing sulfur components having a certain concentration suitable for pest control, an aqueous potassium hydroxide solution is first prepared, and a certain amount of sulfuric powder is safely A sulfuric acid aqueous solution mixed with an aqueous solution of potassium hydroxide was prepared and diluted in 2000 times of water to be sprayed on the leaf surface, whereby a sulfuric solution for insect control containing potassium component was maintained while maintaining a certain concentration of sulfur component .

유황(sulfur, 硫黃)은 제3주기 VI족에 속하는 비금속원소로서 상온에서는 황색, 무취의 파삭파삭한 결정체로 이루어져 있고 물에 용해되지 않으며, 녹는 점은 120℃, 비중은 1.92이다. Sulfur (sulfur) is a non-metallic element belonging to Group III VI. It is composed of crisp, yellow, odorless crystals at room temperature and is insoluble in water. Its melting point is 120 ℃ and its specific gravity is 1.92.

고온에서는 금과 백금을 제외한 거의 모든 금속이나 수소와 화합하여 황화물을 만든다. 점화하면 청색의 불꽃이 생기며, 화약과 성냥의 원료, 약용·농약·펄프 제조 등 매우 다양한 분야에서 광범위하게 사용되는데, 특히 농업 분야에서는 농약, 병충해 방제, 사료 첨가제, 비료 등으로 사용되며 물에 희석하여 해충방제로 사용할 수 있다.At high temperatures, it combines with almost all metals and hydrogen except gold and platinum to form sulfides. It is used in a wide variety of fields such as pharmaceuticals, agrochemicals and pulp production, especially in agricultural fields. It is used as agricultural chemicals, pesticide control, feed additive, fertilizer, etc. and diluted with water Can be used as a pest control.

이러한 유황은 식물성장에 필요한 질소, 인, 칼륨,(칼슘, 마그네슘)과 더불어 3요소(5요소)에 이어서 필요한 미량요소에 포함되며, 식물체 내에서 단백질과 비타민, 효소의 구성성분일 뿐만 아니라 지방의 구성성분이기도 하여 식물의 종류에 따라서 성장에 중요한 역할을 하게 된다.These sulfur are included in the trace elements needed following the three elements (5 elements) in addition to the nitrogen, phosphorus, potassium, (calcium, magnesium) necessary for plant growth and are not only constituents of proteins, vitamins and enzymes in the plant, And it plays an important role in growth depending on the kind of plant.

또한, 유황은 식물에서 우수한 살균, 살충 작용을 하는 것으로 알려져 있으며 주로 흰가루병, 노균병, 곰팡이, 응애 등을 죽이거나 억제하는 효과가 크며 인체에 해가 거의 없는 것으로 알려져 있기 때문에 비료와 농약으로 이용되며 비료의 경우, 유안 등의 비료나 황토 등의 황산화물 형태로 물에 녹아 식물에 흡수되며 일부는 황산의 형태로 다른 금속과 반응하여 금속 황산염의 형태로 금속과 같이 식물에 흡수된다. In addition, sulfur is known to exert excellent sterilization and insecticidal action in plants, and it is used as fertilizer and pesticide because it is known to kill or inhibit mainly powdery mildew, naturally infectious disease, fungus, mite and the like, In the case of fertilizers such as yuan and sulfuric acid such as loess, it melts in water and is absorbed by plants. In some cases, it reacts with other metals in the form of sulfuric acid and is absorbed by plants like metal in the form of metal sulfate.

농약의 경우 현재는 우수한 농약이 많이 개발되어 사용되기 때문에 과거에 비해서 유황의 사용이 줄어들긴 하였으나, 최근의 친환경 농업과 수산업의 확산으로 그 중요성이 다시 부각되면서 수용성 유황을 이용한 친환경 농산물과 수산물 재배를 시도하는 농가가 크게 증가함에 따라서 유황수용액을 전문적으로 생산, 판매하는 업체도 생겨난 실정이다. In the case of pesticides, the use of sulfur has been reduced compared to the past because many pesticides have been developed and used. However, as the importance of the recent eco-friendly agriculture and fisheries industry has increased, importance of environment-friendly agricultural products and aquatic products As the number of farmers trying to grow has increased, there have been companies that professionally produce and sell sulfuric acid aqueous solutions.

그런데 일반적으로 친환경 영농을 하는 농가에서 유황수용액을 제조하는 방법을 보면, 교반기(M)가 장치된 가열탱크에 물 1,000ℓ를 채운 후 물 1000ℓ에 대하여 시중에서 판매되는 25㎏ 중량의 유황 분말 1포를 넣고 가열탱크를 가열하면서 석회 5㎏을 점차 투입하면서 4~5시간 동안 가열탱크를 가열하여 석회유황 합제형태의 액을 만들고 있지만 이 경우도 투입된 유황의 15~20%만이 용해되므로 완전한 유황수용액을 얻을 수 없는 문제가 있었고, 이로인해 유황이 완전히 녹지 않아서 유황의 농도가 낮게 되는 문제점이 있었다.Generally, in a method of manufacturing an aqueous solution of sulfur in an agricultural farm where eco-friendly farming is performed, 1,000 liters of water is charged into a heating tank equipped with a stirrer (M), and 1 liter of 25 kilograms of sulfur powder And the heating tank is heated while the lime is gradually fed into the heating tank for 4 to 5 hours to make a liquid in the form of a lime sulfur mixture. In this case, however, only 15 to 20% of the input sulfur is dissolved, There is a problem that can not be obtained, and the sulfur does not completely dissolve thereby causing the sulfur concentration to be low.

한편, 수산화칼륨(potassium hydroxide , 水酸化─)은 칼륨의 수산화물로서 화학식은 KOH이며, 가성칼륨 또는 가성칼리라고도 하는데, 조해성이므로, 공기 중에 두면 물을 흡수하여 녹고 이산화탄소를 흡수하여 탄산칼륨이 된다.On the other hand, potassium hydroxide (potassium hydroxide) is a potassium hydroxide, and its chemical formula is KOH. It is also called caustic potassium or caustic potash. It is decomposable, so if it is left in the air, it absorbs water and absorbs carbon dioxide.

특히, 물에 넣으면 발열하면서 잘 녹고, 수용액은 알칼리성을 나타내며 칼륨은 식물의 광합성(탄소동화작용)작용에 영향을 미치는 것으로 잘 알려져 있고, 주로 식물의 뿌리나 줄기, 잎을 튼튼하게 할 뿐만 아니라 병해에 대한 저항성이나 내한성을 높여주는 역할도 하기 때문에 수산화칼륨수용액은 기본적으로 식물에 유익한 작용을 주게 되는 것이다.In particular, it is well known that water is added to water and dissolves well, and aqueous solution shows alkalinity. Potassium is well known to affect the photosynthesis (carbon assimilation) action of plants, and it not only strengthens the roots, stems and leaves of plants, And the potassium hydroxide aqueous solution basically gives a beneficial effect to the plant.

본 발명은 이를 이용하여 식물에 유익하고 방제효과가 높은 유황수용액을 제조하여 해충방제를 할 수 있게 하는 것이다.
The present invention makes it possible to control a pest by preparing a sulfuric aqueous solution which is beneficial to plants and has a high control effect.

본 발명은 물에는 잘 녹지 않는 유황분말을 물에 완전하게 그리고 안전하게 녹일 수 있도록 제조방법과 장치를 개발하고 식물에 유익한 해충방제용 유황수용액을 제조하기 위한 것으로 보다 구체적인 것은, 물에 일정량의 수산화칼륨분말을 넣어 완전하게 녹이고 상기 수산화칼륨수용액의 반응열이 식기전에 일정량의 유황분말을 조금씩 나누어 넣으면서 교반시킴으로써, 유황분말이 수산화칼륨수용액에 녹아 일정비율의 칼륨과 유황성분이 혼합된 유황수용액을 제조하고 이를 2000배의 물에 희석하여 엽면 살포하게 하고, 유황농도가 정확하고 방제 성능이 좋으며, 칼륨성분의 보충이 가능한 해충방제용 유황수용액을 만들어 친환경 영농이 이루어지게 한 것이다.
The present invention relates to a method and an apparatus for producing a sulfur powder which is insoluble in water completely and safely in water and to produce an aqueous sulfur solution for controlling pests which is useful for plants. More specifically, a certain amount of potassium hydroxide And the reaction heat of the potassium hydroxide aqueous solution was mixed with a small amount of a predetermined amount of sulfur powder before mixing to prepare a sulfur aqueous solution in which a certain amount of potassium and sulfur components were mixed in an aqueous solution of potassium hydroxide to prepare a sulfur aqueous solution It is diluted in water of the ship and sprayed on the leaf surface, and the sulfur concentration is correct, the control performance is good, and the sulfur solution for pest control is made to be able to replenish the potassium component.

본 발명은 내부에 교반기(2)가 장치된 일정용량의 용해조(1)를 만들어 상기 용해조내의 상단부에 장치된 개폐형뚜껑(1a)에 물주입구(1b)와 투입구(1e)를 만들어 투입구(1e)에는 수산화칼륨분말 및 유황분말 투입기(5)를 장치한 제조장치를 준비하고, 상기 제조장치의 용해조에 물40ℓ를 넣고 물 40ℓ에 수산화칼륨분말 20~25㎏을 투입하는 비율로 수산화칼륨분말을 투입하고 용해시켜 수선화칼륨수용액을 제조하는 단계와, 상기 수산화칼륨수용액에 수산화칼륨수용액의 38~45중량% 되는 량의 유황 분말을 넣고 용해시켜 수산화칼륨수용액이 혼합된 유황수용액을 제조하는 단계와, 수산화칼륨이 혼합된 유황수용액을 2000배의 물에 희석하여 엽면 살포하게 한 해충 방제용 유황수용액을 제조하는 방법이다.
A water injection port 1b and an inlet port 1e are formed in an openable lid 1a provided at an upper end portion of the dissolution tank so as to have a constant capacity of a melting vessel 1 equipped with a stirrer 2 therein, , 40 L of water was added to a dissolution tank of the above production apparatus, and potassium hydroxide powder was added at a rate of 20 to 25 kg of potassium hydroxide powder to 40 L of water Preparing an aqueous solution of potassium hydroxide by dissolving potassium hydroxide in an aqueous solution of potassium hydroxide in an amount of 38 to 45% by weight to prepare a sulfuric acid aqueous solution mixed with an aqueous potassium hydroxide solution; Potassium sulfate mixed aqueous solution is diluted with 2000 times of water and sprayed on the leaf surface, thereby producing an aqueous sulfur solution for pest control.

이와 같이 된 본 발명은 유황분말을 녹이기 위해 먼저 수산화칼륨수용액을 제조하고 수산화칼륨수용액의 반응열이 식기전에 유황분말을 투입하여 유황분말을 녹이기 때문에 용해에 소요되는 시간을 크게 단축할 수 있을 뿐만 아니라 유황을 완전하게 녹일 수 있고, 또 유황수용액에 수산화칼륨 성분이 혼합된 수용액을 제조할 수 있기 때문에 상기 방법으로 얻은 유황수용액을 2000배의 물에 희석하여 농작물에 엽면살포함으로써, 농작물의 살균, 살충이 가능하여 병충해 방제를 할 수 있는 효과가 있고, 농작물에 필요한 칼륨성분을 공급할 수 있는 이점을 얻을 수 있다.In the present invention as described above, an aqueous solution of potassium hydroxide is first prepared to dissolve the sulfur powder, and the reaction heat of the aqueous potassium hydroxide solution dissolves the sulfur powder by introducing the sulfur powder before the cooling, so that the time required for dissolution can be shortened, And an aqueous solution in which a potassium hydroxide component is mixed with an aqueous sulfuric acid solution can be produced. Therefore, the sulfuric acid aqueous solution obtained by the above method is diluted in 2000-fold water and sprayed on the leaf surface of the crop, It is possible to control the insect pests, and it is possible to obtain the advantage that the potassium component necessary for the crops can be supplied.

또한, 본 발명은 유황분말을 녹이기 위해 먼저 수산화칼륨수용액을 제조하고 수산화칼륨수용액의 반응열이 식기전에 유황분말을 투입하여 용해시킴으로써 물을 가열하는 장치가 불필요하여 가열설비가 필요 없기 때문에 설비비용을 최소화할 수 있으며, 수산화칼륨분말을 물에 넣으면 수산화칼륨분말이 물과 반응하면서 용해하기 때문에 반응열이 발생하게 되고 반응열이 식기전에 일정비율의 유황분말을 넣고 교반하면서 용해하기 때문에 완전하게 유황을 녹일 수 있고, 또 15~20분내에 완전하게 녹일 수 있는 이점이 있으며, 수산화칼륨수용액이 유황수용액에 함유된 유황수용액 제조가 가능하여 칼륨성분이 혼합된 해충 방제용 유황수용액 제조가 이루어져 친환경 영농이 가능케 된다.In addition, the present invention minimizes the facility cost by preparing an aqueous solution of potassium hydroxide to dissolve the sulfur powder and heating the water by dissolving the sulfur powder into the reaction vessel before the cooling of the water, When potassium hydroxide powder is put into water, potassium hydroxide powder dissolves while reacting with water, so a reaction heat is generated. Since the reaction heat dissolves while mixing a certain amount of sulfur powder with stirring, it can completely dissolve sulfur And it is also possible to completely dissolve in 15 to 20 minutes. It is possible to manufacture an aqueous sulfuric acid solution containing an aqueous solution of potassium hydroxide in an aqueous sulfuric acid solution, thereby preparing an aqueous sulfuric acid solution for pest control mixed with a potassium component.

그리고 본 발명은 제조장치에 수산화칼륨분말과 유황분말을 안전하게 투입할 수 있는 투입기가 장치되어 있으므로 수산화칼륨분말을 물에 투입하거나 수산화칼륨수용액에 유황분말을 투입할 때 조금씩 나누어서 차근차근 투입할 수 있고, 이로인해 투입단계에서 용액이 끓어 넘치는 현상을 예방할 수 있게 되므로 작업이 안전하고 수산화칼륨과 유황성분의 함량이 정확하게 유지되는 유황수용액을 만들 수 있는 이점이 있다.
Since the present invention is equipped with a charging device capable of safely charging potassium hydroxide powder and sulfur powder into the production apparatus, when the potassium hydroxide powder is put into water or the sulfur powder is put into the aqueous potassium hydroxide solution, , Which makes it possible to prevent the boiling of the solution at the input stage, which makes it possible to make a sulfur aqueous solution which is safe for operation and maintains the contents of potassium hydroxide and sulfur components accurately.

도 1은 본 발명의 제조장치 단면 예시도이다.1 is a cross-sectional view of a manufacturing apparatus of the present invention.

이하, 본 발명을 바람직한 실시 예에 의하여 더욱 구체적으로 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to preferred embodiments.

먼저, 본 발명은 내부에 교반기(2)가 장치되어 모터(3)로 구동되는 일정용량의 용해조(1)를 만들어 상기 용해조내의 상단부에 장치된 개폐형뚜껑(1a)에 물주입구(1b)와 투입구(1e)를 형성하여 투입구(1e)에는 내부에 스크류이송기(6a)가 장치되어 입구(5a)를 통해 내부에 투입한 수사화칼륨분말 또는 유황분말을 일정량씩 이동시켜 배출구(5b)를 통해 용해조(1)의 투입구(1e)로 조금씩 투입할 수 있게 한 투입기(5)를 장치하고 용해조 저부로 용액배출관(1c)이 형성되어 개폐밸브(1d)가 장치되어 관리되는 제조장치를 사용하여 반제용 유황수용액을 제조한다.The present invention is characterized in that a stirrer 2 is installed in the inside of a dissolving tank to make a melting vessel 1 having a fixed capacity driven by a motor 3 and a water inlet 1b, A screw conveyor 6a is installed in the inlet port 1e to move a predetermined amount of the potassium sulfide powder or sulfur powder injected through the inlet port 5a into the melting vessel 1b through the outlet 5b, (1d) to the inlet (1e) of the dissolution tank (1), and a solution discharge pipe (1c) is formed at the bottom of the dissolution tank and the open / close valve (1d) Sulfur aqueous solution is prepared.

본 발명은 용해조에 물을 넣고, 상기 물40ℓ에 수산화칼륨분말 20~25㎏을 투입하는 비율로 수산화칼륨분말을 물에 투입하게 되는데, 이때 투입기(5)를 이용하므로 수산화칼륨분말을 조금씩 나누어서 서서히 물에 투입시킬 수 있고, 교반기(2)에 의하여 교반이 되므로 안전하게 투입될 수 있을 뿐 아니라 급격한 반응에 의하여 용액이 외부로 넘쳐나는 현상을 방지하게 되므로 15~20분안에 안전하고 완전한 용해가 이루어진다.In the present invention, water is put into a dissolution tank, and potassium hydroxide powder is put into water at a rate of adding 20 to 25 kg of potassium hydroxide powder to 40 liters of water. At this time, the potassium hydroxide powder is gradually divided It can be put into water and stirred by the agitator 2, so that it can be safely injected and also prevents the solution from overflowing due to abrupt reaction, so that safe and complete dissolution is achieved in 15 to 20 minutes.

수산화칼륨(potassium hydroxide , 水酸化─)은 칼륨의 수산화물로서 화학식은 KOH이며, 가성칼륨 또는 가성칼리라고도 하는데, 조해성이므로, 공기 중에 두면 물을 흡수하여 녹고 이산화탄소를 흡수하여 탄산칼륨이 된다.Potassium hydroxide (potassium hydroxide) is a potassium hydroxide whose chemical formula is KOH. It is also called caustic potassium or caustic potassium. It is decomposable, so if it is left in the air, it absorbs water and absorbs carbon dioxide.

특히, 물에 넣으면 발열하면서 잘 녹고, 수용액은 알칼리성을 나타내며 칼륨은 식물의 광합성(탄소동화작용)작용에 영향을 미치는 것으로 잘 알려져 있고, 주로 식물의 뿌리나 줄기, 잎을 튼튼하게 할 뿐만 아니라 병해에 대한 저항성이나 내한성을 높여주는 역할도 하기 때문에 수산화칼륨수용액은 기본적으로 식물에 유익한 작용을 주게 된다.In particular, it is well known that water is added to water and dissolves well, and aqueous solution shows alkalinity. Potassium is well known to affect the photosynthesis (carbon assimilation) action of plants, and it not only strengthens the roots, stems and leaves of plants, And the potassium hydroxide aqueous solution basically gives a beneficial effect to the plant.

따라서 물에 수산화칼륨분말을 넣고 교반하게 되면, 수산화칼륨이 물과 반응하여 발열하면서 녹기 때문에 용해조에 담긴 물의 온도가 100℃ 이상으로 끓어오르게 된다.Therefore, when potassium hydroxide powder is added to water and stirred, potassium hydroxide reacts with water to dissolve while heating, so that the temperature of the water contained in the dissolution tank is boiled to 100 ° C or more.

그러므로 용해조를 외부에서 가열하지 않아도 100℃이상의 열을 가진 고온의 수산화칼륨수용액을 만들 수 있으며, 수산화칼륨수용액이 식기전에 투입기를 이용하여 용해조 내부의 수산화칼륨수용액에 수산화칼륨수용액의 38~45중량% 범위내에 해당하는 량의 유황분말을 투입하게 되는데 이때에도 투입기를 통해 투입함으로써, 일정량의 유황분말이 조금씩 나누어져 서서히 투입되고 교반이 이루어지므로 반응작용의 영향에 의하여 물이 끓어 오르지 않고 안전하게 유황분말을 용해시 킬 수 있어서 15~20분내에 용해가 이루어진다.Therefore, a high-temperature potassium hydroxide aqueous solution having a heat of 100 DEG C or more can be produced without heating the dissolution tank from the outside, and a potassium hydroxide aqueous solution can be prepared by adding 38 to 45% by weight of an aqueous solution of potassium hydroxide to an aqueous solution of potassium hydroxide in the dissolution tank, The amount of the sulfur powder is injected into the reaction vessel at the same time, and a certain amount of the sulfur powder is gradually divided into a small amount of the sulfur powder to be stirred. Thus, the reaction does not boil the water, And dissolves in 15 to 20 minutes.

이는 수산화칼륨이 물과 반응하여 발생한 열과 화학작용에 의거 유황분말이 빠르게 녹아 용해가 되기 때문이다.This is because sulfuric acid dissolves rapidly due to heat and chemical action caused by reaction of potassium hydroxide with water.

따라서 완전하게 녹은 유황수용액에는 수산화칼륨 성분이 함유되게 된다.Therefore, the completely dissolved sulfuric acid aqueous solution contains a potassium hydroxide component.

이어서 수산화칼륨이 함유된 유황수용액을 250cc병에 넣고 물500ℓ에 타서 2000배로 희석하여 농작물에 엽면 살포할 수 있게 한 해충방제용 유황수용액을 제조하는 것이다.Then, the sulfuric aqueous solution containing potassium hydroxide is put into a 250 cc bottle and diluted to 500 times with water to prepare a sulfuric aqueous solution for pest control, which can be sprayed on the crops.

이상에서는 본 발명의 바람직한 실시 예에 대하여 도시하고 설명하였으나, 본 발명은 상술한 특정의 실시 예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술 분야에서 통상의 지식을 가진 자에 의해 다양한 변형 실시나 응용이 가능한 것은 물론이고, 이러한 변형 실시나 응용 예는 본 발명의 기술적 사상이나 전망으로부터 개별적으로 이해돼서는 안 될 것이다.
