기화기를 구비한 훈증 장치Fumigation device with vaporizer
본 발명은 전기 히터식 기화기를 포함하는 훈증 장치에 관한 것으로서, 더욱 상세하게는 과일 또는 야채 등을 수입하여 훈증 소독을 실시하는 경우, 불을 직접 이용하는 버너를 사용하지 않음으로써 화재 위험 및 고온의 물과 오일 등으로 인한 화상 위험 등을 예방하고, 액화된 가스와 훈증제를 기화하여 훈증함으로써 가스와 훈증제를 별도로 사용하는 경우보다 기화요율을 높이고, 다양한 종류의 훈증제에도 사용할 수 있는 전기 히터식 기화기를 구비한 훈증 장치에 관한 것이다.The present invention relates to a fumigation device including an electric heater-type vaporizer, and more particularly, when fumigation is performed by importing fruits or vegetables, fire risk and high-temperature water are reduced by not using a burner that directly uses fire. Equipped with an electric heater type vaporizer that can be used for various types of fumigants and increases the vaporization rate compared to the case of using gas and fumigants separately by preventing the risk of burns caused by oil and gas, and vaporizing and fumigating liquefied gas and fumigants. It is about a fumigation device.
농산물, 목재류, 과실류, 채소류 등을 수입하는 경우 수출입식물 검역소독처리규정에 의거하여 해당 수출입 식물에 병해충이 있는지의 여부를 검사를 받고, 훈증 소독, 열처리, 약제 침지 등의 처리를 하여야 한다.In the case of importing agricultural products, timber, fruits, vegetables, etc., the exported and imported plants must be inspected for pests and fumigation, heat treatment, and drug immersion in accordance with the import and export plant quarantine treatment regulations.
훈증 소독은, 창고 또는 컨테이너와 같은 공간에 과실류, 농산물, 목재류 등을 놓은 후, 액체 상태의 훈증제를 가스 상태로 기화하고, 고압 상태의 불활성가스를 이용하여 기화된 훈증제를 일정 시간 이상 분사하여 병해충을 사멸하는 것을 말한다. Fumigation disinfection is performed by placing fruits, agricultural products, timber, etc. in a space such as a warehouse or container, vaporizing the liquid fumigant into a gaseous state, and spraying the vaporized fumigant for a certain period of time using high-pressure inert gas to kill pests and diseases. means to perish
목재류에는 훈증제로 MB를 원제로 하는 메틸브로마이드 제품이, 곡물, 담배 등에는 PH3(인화수소, 포스핀)을 원제로 하는 에피흄이나 비바킬 제품이, 바나나 등에는 EF(에틸포메이트)를 원제로 하는 베이퍼메이트 제품이 주요 사용되고 있으며, 이런 훈증제를 분사하는 불활성가스로는 질소가 많이 사용된다.Methyl bromide products based on MB as a fumigant for wood products, epifume or non-vaccyl products based on PH3 (hydrogen phosphine, phosphine) for grains and tobacco, and EF (ethyl formate) as a source material for bananas, etc. Vapormate products are mainly used, and nitrogen is widely used as an inert gas for spraying these fumigants.
훈증제에는 인체에 유해한 독성 물질이 함유되어 있어서, 훈증 소독을 실시하기 위해서는 소독처리기준에서 규정하고 있는 요건을 만족해야 한다. 훈증 소독은 자격요건을 갖춘 방제 기술자의 입회하에 실시하여야 하며, 소독 시간, 훈증제의 사용량 등에도 제한이 있다.Fumigants contain toxic substances that are harmful to the human body, so in order to conduct fumigation, the requirements stipulated in the disinfection treatment standards must be satisfied. Fumigation disinfection must be carried out in the presence of a qualified control engineer, and there are restrictions on disinfection time and the amount of fumigants used.
종래 과일 훈증 소독 방식에 의하면, 창고 내에 과일 상자를 일부 개방하여 적재하고 천막과 비닐 시트로 과일 상자를 감싼 후, 천막 내부에 가스 상태의 훈증제를 분사하여 일정 시간 동안 훈증 소독을 실시하였다.According to the conventional fruit fumigation method, fruit crates are partially opened and loaded in a warehouse, covered with tents and vinyl sheets, and fumigation is performed for a certain period of time by spraying a gaseous fumigant into the tent.
액체 상태의 훈증제를 가스 상태로 만들기 위하여, 버너로 물을 끓이고, 100℃ 끓는 물과 대기압 하에서 플라스틱 통에 들어 있는 액체 상태의 훈증제와의 열교환을 통해 훈증 가스를 만들고, 고압의 가스로 이를 천막 등과 같은 곳의 내부에 분사하는 방식이었다. 바나나 등의 훈증에 사용되는 베이퍼메이트 제품은 기화 온도가 57℃ 정도이어서, 100℃에서 끓고 있는 뜨거운 물과의 열교환을 통해 기화가 되는 점을 이용하는 것이었다.In order to turn the liquid fumigant into a gaseous state, water is boiled with a burner, and fumigating gas is produced through heat exchange between 100°C boiling water and the liquid fumigant contained in a plastic container under atmospheric pressure, and the fumigant is heated with high-pressure gas to a tent, etc. It was a method of spraying inside the same place. Vapormate products used for fumigation of bananas have a vaporization temperature of about 57 ° C, so they are vaporized through heat exchange with hot water boiling at 100 ° C.
이와 같은 방식은 재래식으로, 물을 끓이고 증발한 만큼 물을 채워야 하다 보니 장치가 커지는 점, 불을 사용하다 보니 화재 발생 우려가 있는 점, 뜨거운 물을 사용하다 보니 열교환 효율이 그리 높지 않고 작업자에게 화상을 입힐 수 있는 점, 100℃ 물과의 열교환을 하다 보니 그 이상의 온도에서 기화되는 훈증제에 사용하기 어려운 문제점이 존재하였다.This method is a conventional method, and since water must be boiled and filled with evaporated water, the device becomes larger, fire is used, and there is a risk of fire. There were problems in that it could be applied to fumigants that vaporized at a temperature higher than that due to heat exchange with water at 100 ° C.
이런 문제점을 해결하기 위하여, 도 1에 개시되어 있는 기술이 개발되었다. 도 1은 등록특허공보 제10-1416299호에 개시되어 있는 것인데, 내부에 물이 저장되는 기화기 본체(600), 상기 기화기 본체(600)의 하부에 구비되어 물을 가열하는 전기 히터(610), 복수의 고압가스통(500)과 연결되어 훈증제를 기화기 본체(600)로 유입시키기 위한 복수의 인렛 밸브(510), 상기 인렛 밸브(510)를 통합하여 기화기 본체(600)에 연결하는 인렛 헤더(520), 상기 기화기 본체(600)에 내장되어 고온의 물에 의해 가열되는 히팅 파이프(570), 상기 기화기 본체(600)의 일측에 구비되어 기화된 훈증가스를 배출시키기 위한 아웃렛 밸브(550), 상기 기화기 본체(600)와 각각의 아웃렛 밸브(550)를 연결하는 아웃렛 헤더(540)를 포함하는 훈증장치 구성을 개시하고 있다.To solve this problem, the technique disclosed in FIG. 1 has been developed. 1 is disclosed in Patent Registration No. 10-1416299, a vaporizer body 600 in which water is stored, an electric heater 610 provided at the bottom of the vaporizer body 600 to heat water, A plurality of inlet valves 510 connected to a plurality of high-pressure gas cylinders 500 to introduce fumigants into the vaporizer body 600, and an inlet header 520 that integrates the inlet valves 510 and connects them to the vaporizer body 600 ), a heating pipe 570 built into the vaporizer body 600 and heated by high-temperature water, an outlet valve 550 provided on one side of the vaporizer body 600 to discharge vaporized fumigation gas, the Disclosed is a fumigator configuration including an outlet header 540 connecting a vaporizer body 600 and each outlet valve 550.
종래기술은 기화기 본체(600) 내부에 있는 물을 전기 히터(610)로 끓이고, 고압가스를 이용하여 액상의 훈증제를 물에 의해 가열되어 있는 히팅 파이프(570)로 보내어 열교환을 통해 훈증가스를 만들어 배출하는 기술이다.In the prior art, water in the vaporizer body 600 is boiled with an electric heater 610, and a liquid fumigant is sent to a heating pipe 570 heated by water using high-pressure gas to generate fumigant gas through heat exchange. It is a technology that releases
이와 같은 방식은 종래 버너와 같은 방식을 전기 히터 방식으로 대체한 것으로, 여전히 열교환을 통해 대기압 상태로 플라스틱 통에 있는 액상의 훈증제를 가열하는 것으로서, 뜨거운 물을 사용하다 보니 열교환 효율이 그리 높지 않고, 뜨거운 물의 폭발 등으로 작업자에게 화상을 입힐 수 있는 문제점이 존재하였다.This method replaces the conventional burner method with an electric heater method, and still heats the liquid fumigant in a plastic container at atmospheric pressure through heat exchange. Since hot water is used, the heat exchange efficiency is not very high, There was a problem that the worker could be burned due to the explosion of hot water.
아울러 열교환 매체로 물을 사용하다 보니 물보다 기화 온도가 높은 훈증제에 사용하는 것에는 어려움이 있었으며, 훈증제와 고압가스를 별도로 준비해야 하는 등의 여러 문제점 등이 존재하였다.In addition, since water is used as a heat exchange medium, it is difficult to use it for a fumigant having a higher vaporization temperature than water, and there are various problems such as the need to separately prepare the fumigant and high-pressure gas.

첨부된 도면을 참조하여 본 발명의 실시예들을 설명한다. 이런 실시예들은 본 발명을 쉽게 설명하기 위한 것이며, 본 발명이 이런 실시예들에 한정되지는 않는다.　본 출원에서 사용한 용어는 특정 실시예를 설명하기 위해 사용되었으며, "포함하다" 또는 "가지다" 등의 용어는 구성 등이 존재한다는 것을 의미한다.Embodiments of the present invention will be described with reference to the accompanying drawings. These embodiments are intended to easily explain the present invention, and the present invention is not limited to these embodiments. Terms used in this application are used to describe specific embodiments, and terms such as “include” or “have” mean that a configuration or the like exists.
도 2에는 본 발명의 일 실시예에 따른 회로도가 도시되어 있으며, 이를 바탕으로 설명한다.2 shows a circuit diagram according to an embodiment of the present invention, and will be described based on this.
저장통(200)에는 일정 압력 하에서, 이산화탄소와 훈증제가 함께 액체 상태로 저장되어 있다. In the reservoir 200, carbon dioxide and a fumigant are stored together in a liquid state under a certain pressure.
이산화탄소는 압력에 따라서 -50 ℃ 이하에서 액화가 되고, 훈증제는 통상 액체 상태에 있으므로, 저장통(200)은 -50 ℃ 이하이며 이산화탄소가 액화되는 압력에서, 훈증제와 이산화탄소 모두 같이 액화가 되어 있다고 할 수 있다.Since carbon dioxide is liquefied at -50 ° C or lower depending on the pressure, and the fumigant is usually in a liquid state, it can be said that both the fumigant and carbon dioxide are liquefied at the pressure at which the storage tank 200 is -50 ° C or lower and the carbon dioxide is liquefied. there is.
종래에는 고압의 질소를 이용하여, 대기압 액체 상태의 베이퍼메이트를 열교환한 후 기화하여 분사하는 방식이 사용되었는데, 본 발명은 함께 액화되어 있는 이산화탄소와 훈증제를 사용함으로써, 종래기술의 질소, 베이퍼메이트를 별도로 준비하고 훈증 가스 생성을 위하여 연결하여야 하는 점, 고압의 질소를 분사하는 과정에서 베이퍼메이트를 기화하기 위한 열에 대한 화재의 우려 등을 제거할 수 있게 되었다.Conventionally, a method of vaporizing and spraying vapor mate in a liquid state at atmospheric pressure using high-pressure nitrogen was used. It is possible to eliminate the need to prepare separately and connect for fumigation gas generation, and the concerns of fire due to heat to vaporize vapor mate in the process of spraying high-pressure nitrogen.
본 발명은 액체 상태의 이산화탄소를 사용하는데, 질소의 경우 액화 온도가 -196℃ 이하이어서, 그것보다는 액화 온도가 높은 이산화탄소를 사용하여 효율성을 높이고 있다.The present invention uses carbon dioxide in a liquid state. In the case of nitrogen, the liquefaction temperature is less than -196 ° C.
액체 상태인 훈증제와 이산화탄소가 저장되어 있는 저장통(200)은, 훈증 장치와 결합 또는 해체됨에 있어서, 퀵 커플러(110)를 통해 이루어진다. 저장통(200)에는 액체 상태의 훈증제와 이산화탄소를 토출하는 배관이 있고, 훈증 장치에는 유입하는 배관이 있는데, 토출하는 배관과 유입하는 배관의 각 끝 부분에 암수 부분이 있어서 퀵 커플러 결합이 가능하도록 한 것이다.The storage container 200 in which liquid fumigants and carbon dioxide are stored is coupled to or disengaged from the fumigation device through the quick coupler 110. The reservoir 200 has a pipe for discharging the liquid fumigant and carbon dioxide, and the fumigation device has an inflow pipe. There are male and female parts at each end of the discharge pipe and the inflow pipe to enable quick coupler coupling. will be.
퀵 커플러(110)는 일종의 원터치 커플러이며, 저장통(200)은 사용 후 새로운 저장통과의 쉬운 교체, 훈증 기화 장치를 사용하지 않는 경우 훈증 기화 장치와 저장통(200)과의 쉬운 분리를 위하여 채택된 것이라 할 수 있다. .The quick coupler 110 is a kind of one-touch coupler, and the reservoir 200 is adopted for easy replacement with a new reservoir after use and easy separation of the fumigation device and the reservoir 200 when the fumigation device is not used. can do. .
저장통(200)과 훈증 장치가 퀵 커플러(110)를 통해 결합되는 경우, 액체 상태의 훈증제와 이산화탄소는 압력에 의거하여 배관을 타고 유입되어 복수로 분배하는 분배 밸브(140)를 거친다. When the storage container 200 and the fumigation device are coupled through the quick coupler 110, the fumigant and carbon dioxide in a liquid state are introduced through a pipe based on pressure and pass through a distribution valve 140 for distributing a plurality of them.
도 4에서 볼 수 있는 바와 같이, 분배 밸브(140)에는 유입구와 훈증제와 복수의 유출구가 형성되어 있다. 분배 밸브(140)는 유입된 이산화탄소와 훈증제를 복수의 유출구로 훈증제와 이산화탄소를 균등하게 분배하는 기능을 한다.As can be seen in FIG. 4 , the distribution valve 140 has an inlet, a fumigant, and a plurality of outlets. The distribution valve 140 functions to equally distribute the introduced fumigant and carbon dioxide to a plurality of outlets.
4개로 분배하는 경우, 분배 밸브(140)는 가로 세로 방향이 정사각형인 직육면체 또는 정육면체 형상을 하고, 윗면에 유입구가 형성되고, 4측면에 유출구가 형성된다. 윗면으로부터 유입된 유체가 내부를 지나 십자 형태로 서로 관통되어 있는 관통홀을 지나 4측면에 형성된 유출구를 통해 유출되는 것이다.In the case of distributing to four, the distribution valve 140 has the shape of a rectangular parallelepiped or a regular hexahedron in which the vertical and horizontal directions are square, and has an inlet on the upper surface and an outlet on the four sides. The fluid introduced from the upper surface flows through the through hole passing through each other in a cross shape through the inside and out through the outlet formed on the 4 sides.
분배 밸브(140)를 통해 분배된 훈증제와 이산화탄소는 각각 분배 배관(141, 142, 143, 144), 기화시키는 히터부(150, 151, 152, 153), 병합 배관(161,162, 163, 164)을 거친 후, 최종적으로 병합 밸브(160)에서 다시 모아져 기화된 상태로 유출되며, 기화된 훈증 가스는 훈증을 위한 창고 또는 컨테이너 등으로 향하게 된다. The fumigant and carbon dioxide distributed through the distribution valve 140 pass through the distribution pipes 141, 142, 143, and 144, the vaporizing heater units 150, 151, 152, and 153, and the merging pipes 161, 162, 163, and 164, respectively. After roughening, it is finally collected again in the merging valve 160 and discharged in a vaporized state, and the vaporized fumigation gas is directed to a warehouse or container for fumigation.
복수의 분배 배관(141, 142, 143, 144)은 유입된 훈증제와 이산화탄소를 복수로 분배하여 토출하는 분배 밸브(140)와 히터부(150, 151, 152, 153) 사이에 설치된다. 복수의 분배 배관은 그들 사이에서 이산화탄소와 훈증제의 압력과 유량 불균형을 방지하기 위하여, 길이, 직경, 설치 위치, 높이 등이 동일한 것이 바람직하다.The plurality of distribution pipes 141, 142, 143, and 144 are installed between the distribution valve 140 and the heater units 150, 151, 152, and 153 for distributing and discharging the introduced fumigant and carbon dioxide in plurality. It is preferable that the plurality of distribution pipes have the same length, diameter, installation position, height, etc., in order to prevent pressure and flow imbalance of the carbon dioxide and the fumigant therebetween.
이렇게 분배 밸브(140)를 통해 유출된 유체는 복수의 분배 배관(141, 142, 143, 144)을 거친 후 히터부(150, 151, 152, 153)에 유입된다.The fluid discharged through the distribution valve 140 passes through a plurality of distribution pipes 141 , 142 , 143 , and 144 and then flows into the heater units 150 , 151 , 152 , and 153 .
히터부(150, 151, 152, 153)는 열에 의하여 액체를 기화시키는 기화기 역할을 한다. 전기 히터 방식으로 이산화탄소와 훈증제가 열매유 없이 히터부와 직접 접촉하는 직렬식으로 가열된다.The heater units 150, 151, 152, and 153 serve as vaporizers that vaporize liquid by heat. As an electric heater method, carbon dioxide and fumigants are heated in series without thermal oil in direct contact with the heater part.
바나나 등의 훈증에 사용되는 베이퍼메이트 훈증제의 기화 온도는 57℃ 정도이고, 이산화탄소의 기화 온도는 이것보다 훨씬 낮기 때문에, 이산화탄소가 먼저 기화되고 그에 이어 훈증제가 기화된다. 본 발명에서 먼저 기화된 이산화탄소는 나중에 기화된 훈증제를 분사하는 역할을 하게 된다.Since the vaporization temperature of the vapor mate fumigant used for fumigation of bananas is about 57° C., and the vaporization temperature of carbon dioxide is much lower than this, carbon dioxide is vaporized first and then the fumigant is vaporized. In the present invention, the carbon dioxide vaporized first plays a role of spraying the vaporized fumigant later.
각 히터부(150, 151, 152, 153)에서 기화된 훈증제는 병합 배관(161, 162, 163, 164)을 거친 후, 그들을 하나로 모으는 병합 밸브(160)를 거쳐 최종적으로 훈증 장치로부터 분사된다. The fumigants vaporized in each of the heater units 150, 151, 152, and 153 pass through the merging pipes 161, 162, 163, and 164, and then pass through the merging valve 160 to collect them into one, and are finally sprayed from the fumigation device.
분배 배관(141, 142, 143, 144)처럼 병합 배관(161, 162, 163, 164) 역시 그 길이, 직경 및 설치 높이를 동일하게 하여, 압력, 유량 등에 불균형이 발생하지 않도록 한다.Like the distribution pipes 141, 142, 143, and 144, the merging pipes 161, 162, 163, and 164 also have the same length, diameter, and installation height to prevent imbalance in pressure and flow rate.
다음으로 본 발명의 훈증 장치 작동 방법에 대하여 설명한다. Next, the method of operating the fumigation device of the present invention will be described.
저장통(200)에서 나온 액체 상태의 훈증제와 이산화탄소는 유량 조절 밸브(120)를 거쳐 분배 밸브(140)에 유입된다. The liquid fumigant and carbon dioxide from the reservoir 200 pass through the flow control valve 120 and flow into the distribution valve 140.
초기 작동시 유량 조절 밸브(120) 후단에 있는 압력계(130)과 기화훈증 장치의 출구에 있는 온도계(170)의 상태를 보면서 유량 조절 밸브(120)를 조절한다. 초기 작동 상태에는 이산화탄소와 훈증제가 액상이므로 유량 조절 밸브(120)의 개도가 많이 열리는 경우 액상 이산화탄소와 훈증제가 토출되어 과일 등에 직접 분사될 수 있으므로, 그런 현상을 방지하기 위하여 유량 조절 밸브(120)의 개도를 작게한 상태에서 온도계의 온도에 맞추어 조금씩 개도를 크게 하는 것이다. During initial operation, the flow control valve 120 is adjusted while observing the conditions of the pressure gauge 130 at the rear end of the flow control valve 120 and the thermometer 170 at the outlet of the vaporization fumigation device. Since carbon dioxide and the fumigant are liquid in the initial operating state, if the opening of the flow control valve 120 is opened too much, the liquid carbon dioxide and the fumigant may be discharged and directly sprayed on fruits. To prevent such a phenomenon, the flow control valve 120 In the state where the opening degree is small, the opening degree is gradually increased according to the temperature of the thermometer.
최종적으로 유량 조절 밸브(120)의 개도 조절을 통해 압력계(130)에서의 압력은 5kgf/㎠ 이고, 온도는 훈증제에 따라서 그 기화 온도에 맞춰지도록 하는데, 베이퍼메이트인 경우 훈증장치에서 토출되는 온도가 57℃가 유지되도록 한다. 만일 100℃ 이상에서 기화되는 훈증제인 경우, 그 온도가 유지되도록 유량조절 밸브(120)의 개도를 조절해야 한다.Finally, by adjusting the opening of the flow control valve 120, the pressure in the pressure gauge 130 is 5 kgf/cm2 and the temperature is adjusted to the vaporization temperature according to the fumigant. In the case of vapor mate, the temperature discharged from the fumigation device 57°C is maintained. If the fumigant vaporizes at 100° C. or higher, the opening of the flow control valve 120 should be adjusted so that the temperature is maintained.
이런 조절은 작업자가 압력계(130)와 온도계(170)를 보면서 수동으로 할 수 있지만, 압력계(130)와 온도계(170)를 전자식으로 하고 그 신호를 받아서, 유량 조절 밸브(120)의 개도를 자동으로 조절할 수도 있다. 자동으로 조절하는 경우라고 하더라도 훈증 장치에는 온도와 압력을 시각적으로 확인할 수 있는 패널(180)이 추가로 설치되어 있음은 당연하다.Although this adjustment can be done manually by the operator while looking at the pressure gauge 130 and the thermometer 170, the pressure gauge 130 and the thermometer 170 are electronically operated and the opening of the flow control valve 120 is automatically adjusted by receiving the signal. can also be adjusted with Even in the case of automatically adjusting, it is natural that a panel 180 for visually checking the temperature and pressure is additionally installed in the fumigation device.
본 발명에 따른 훈증 장치는 살충, 살균, 제초 효과 등을 가지며, 액화된 이산화탄소 및 훈증제를 같이 사용하는데, 먼저 이산화탄소를 기화하고 나중에 훈증제를 기화함으로써 이산화탄소를 이용하여 훈증제를 분사하는 것으로서, 종전보다 안전하고 효율적인 방법으로 사용할 수 있을 뿐만 아니라 장치의 간소화를 구축할 수 있다.The fumigation device according to the present invention has insecticidal, sterilizing, and herbicidal effects, and uses liquefied carbon dioxide and a fumigant together. It vaporizes carbon dioxide first and vaporizes the fumigant later to spray the fumigant using carbon dioxide, which is safer than before. and can be used in an efficient way, as well as build simplification of the device.

여기에서도 병합 배관(161, 162, 163, 164)에서 병합 밸브(160)에 이르는 배관의 설치 위치, 길이, 두께 등은 동일하다. 도 5는 히터부(150, 151, 152, 153)에 결합된 병합 배관(161, 162, 163, 164)이 프레임(210) 측면을 타고 내려와 프레임 하부 중앙의 병합 밸브(160)에서에서 모아져 토출될 수 있는 것을 개시하고 있다.Also here, the installation position, length, thickness, etc. of the merging pipes from the merging pipes 161, 162, 163, and 164 to the merging valve 160 are the same.
