Description
본 고안은 회전진공증발농축기(rotary vacuum evaporator)에 관한 것으로, 더욱 상세하게는 실험실의 회전진공증발농축기에서 유기용매가스를 냉각, 액화시킨 후 물순환펌프흡입기의 물에 완전 용해되지 않은 유기용매가스를 재차 냉각, 액화시켜 이들 유기용매를 완전 제거하여 실험실내의 공기가 오염되는 것을 방지할 수 있도록 개량한 것이다.The present invention relates to a rotary vacuum evaporator, and more particularly, organic solvent gas that is not completely dissolved in the water of the water circulating pump suction after cooling and liquefying organic solvent gas in a laboratory rotary vacuum evaporator. After cooling and liquefying again, these organic solvents are completely removed to improve the contamination of the air in the laboratory.
도 1에 나타낸 바와 같이 실험실에서 추출 및 농축공정에 널리 사용되는 회전진공증발농축기(20)는 추출하고자 하는 성분을 유기용매로 추출한 후 그 내측에 설치된 냉각관(30)를 따라 순환하는 냉각수를 이용하여 냉각, 액화시키고 액화된 유기용매는 회수병(10)에 수거하여 대기중으로 확산되는 것을 방지하고 있다As shown in FIG. 1, a rotary vacuum evaporator 20 widely used in an extraction and concentration process in a laboratory extracts a component to be extracted with an organic solvent and then uses cooling water circulated along a cooling tube 30 installed therein. By cooling, liquefying, and liquefied organic solvents are collected in the recovery bottle 10 to prevent diffusion into the atmosphere.
그리고 회전진공증발농축기(20)는 일반농축에 적용되는 높은 온도에 따른 변화를 방지하기 위하여 낮은 진공을 이용하여 섭씨 60℃ 정도의 낮은 온도로 증발, 농축한다.In addition, the rotary vacuum evaporator 20 is evaporated and concentrated to a low temperature of about 60 ° C. using a low vacuum in order to prevent the change due to the high temperature applied to the general concentration.
종래에는 수도수를 냉각기(condenser)에 냉각수로 공급하고 수도수의 압력을 이용한 흡입기(aspirator)가 널리 이용되었으나, 최근에는 냉각 효율을 높이고자 수도수 대신 냉동기를 사용하는 순환식 저온항온수조(refregerated bath circulator)로 냉각수를 공급하고 물순환펌프흡입기(21)(water circulating pump aspirator)로부터 낮은 진공을 형성하도록 되어 있다.Conventionally, an aspirator using tap water to supply tap water as a coolant and using tap water pressure has been widely used, but recently, a refrigerated low temperature water tank (refregerated) using a freezer instead of tap water to improve cooling efficiency is provided. The cooling water is supplied to the bath circulator and a low vacuum is generated from the water circulating pump aspirator 21.
이때 유기용매는 회전진공증발농축기(20)의 냉각관(30)에서 냉각, 액화되며 회수병(10)에 모으고 냉각관(30)에서 액화되지 않은 미량의 유기용매가스는 물순환 펌프흡입기(21)내의 물에 용해시키게 된다.At this time, the organic solvent is cooled and liquefied in the cooling tube 30 of the rotary vacuum evaporator 20, collected in the recovery bottle 10, the trace amount of the organic solvent gas not liquefied in the cooling tube 30 is a water circulation pump suction (21). In water).
하지만 종래에는 냉각수로 이용되는 수도수의 경우 계절에 따른 수온상승으로 인해 냉각 효과가 떨어지는 단점이 있고, 냉동기를 이용하는 순환식 저온항온수조를 사용하더라도 냉각, 액화되지 못한 유기용매가스는 물에 대한 용해도가 낮아 물순환펌프흡입기(21)의 수조내 물에 용해되지 않은 유기용매가스는 그대로 실험실내로 확산되어 실내환경오염을 가중시키게 되었다.However, in the case of tap water, which is conventionally used as a cooling water, the cooling effect is inferior due to a seasonal increase in water temperature, and organic solvent gas that is not cooled or liquefied is soluble in water even when a circulating low temperature constant temperature water tank using a freezer is used. Low, the organic solvent gas not dissolved in the water in the water circulation pump inhaler 21 is diffused into the laboratory as it is to increase the indoor environmental pollution.
또한 유기용매가스가 용해된 물은 그대로 폐기시에는 환경오염을 유발하므로 이를 처리하기 위한 별도의 처리 시설이 요구되는 등의 문제점을 안고 있다.In addition, the water in which the organic solvent gas is dissolved causes environmental pollution when disposed as it is, has a problem such as requiring a separate treatment facility for treating this.
본 고안은 상기한 바와 같은 종래의 문제점을 해소하기 위해 안출된 것으로, 본 고안이 해결하고자 하는 기술적 과제는 회전진공증발농축기에서 발생되는 유기용매가스는 냉각관에서 1차로 냉각, 액화시켜 회수병에 모으는 과정에서 액화되지 않은 유기용매가스를 2차냉각기를 이용하여 다시 한번 냉각, 액화시켜 유기용매가스의 제거효과를 높이는데 그 목적이 있다.The present invention was devised to solve the conventional problems as described above, the technical problem to be solved by the present invention is that the organic solvent gas generated in the rotary vacuum evaporator is cooled and liquefied primarily in the cooling tube to the recovery bottle The purpose is to increase the removal effect of the organic solvent gas by cooling and liquefying the organic solvent gas that has not been liquefied in the collecting process by using a secondary cooler.
또한 본 고안은 2차 냉각기에서도 완전히 제거되지 않는 유기용매가스는 활성탄소가 채워진 활성탄 흡착관에 의해 최종 제거할 수 있게함으로써 종래처럼 유기용매가스가 실내를 오염시키게 되는 것을 방지하고자 하는데 있는 것이다.In addition, the present invention is to prevent the organic solvent gas is not completely removed even in the secondary cooler to be finally removed by the activated carbon adsorption tube filled with activated carbon to prevent the organic solvent gas from contaminating the room as conventionally.

In this case, a secondary cooler 50 is provided separately from the rotary vacuum evaporator 20, and the cooling pipe 52 of the secondary cooler 50 circulates the cooling water of the circulating low temperature constant temperature water tank 40. The organic solvent gas that is not liquefied in the rotary vacuum evaporator 20 is characterized by being configured to cool and liquefy once again by the secondary cooler 50.
2차냉각기(50)는 회전진공증발농축기(20)의 냉각관(30)을 따라 순환되는 냉각수를 함께 이용할 수 있도록 순환식저온항온수조(40)의 공급구와 토출구를 2갈래로 분기시켜 일측은 냉각관(30)에 연결하고 타측은 2차냉각기(50)의 냉각관(52)에 각각 연결되고, 회전진공증발농축기(20)와 2차냉각기(50)에는 진공 형성을 위해 진공펌프(60)가 접속되고 있다.The secondary cooler 50 branches the supply port and the discharge port of the circulating low temperature constant temperature water tank 40 into two branches so that the cooling water circulated along the cooling tube 30 of the rotary vacuum evaporator 20 may be used. It is connected to the cooling tube 30 and the other side is connected to the cooling tube 52 of the secondary cooler 50, respectively, the vacuum pump 60 to form a vacuum in the rotary vacuum evaporator 20 and the secondary cooler 50 ) Is connected.
도 3에 나타낸 바와 같이 2차냉각기(50)와 진공펌프(60)가 연결되는 튜브(51)의 중간에는 용매회수용 활성탄소가 가득 채워진 활성탄 흡착관(70)이 설치되고, 상기 활성탄 흡착관(70)은 2차냉각기(50)의 냉각관(52)에 의한 냉각, 액화 과정에서도 액화되지 못한 유기용매가스를 흡착 제거하도록 구성되고 있다.As shown in FIG. 3, an activated carbon adsorption tube 70 filled with a solvent recovery activated carbon is installed in the middle of the tube 51 to which the secondary cooler 50 and the vacuum pump 60 are connected. 70 is configured to adsorb and remove the organic solvent gas that has not been liquefied even during the cooling and liquefaction process by the cooling tube 52 of the secondary cooler 50.
상기 구성에 있어서 2차냉각기(50)의 냉각관(52)은 30cm 길이의 파이렉스(pyrex) 유리제품으로 나선관식 딤로스 관(dimroth condenser)으로 되고 상기 냉각관(52)의 하부측에 설치되는 수기(54)는 300㎖의 파이렉스(pyrex) 유리제품으로 구성되어 상기 2차냉각기(50)로 유입되는 유기용매가스는 냉각관(52)으로 순환되는 냉각수에 의해 다시 냉각, 액화시켜 액화된 유기용매는 그 하부측에 부설되는 수기(54)에 모두 모으도록 되고 있다.In the above configuration, the cooling tube 52 of the secondary cooler 50 is a 30 cm long pyrex glass product, which is a spiral dimroth condenser and is installed on the lower side of the cooling tube 52. The water tank 54 is composed of 300 ml of pyrex glass products, and the organic solvent gas flowing into the secondary cooler 50 is cooled and liquefied again by the cooling water circulated to the cooling pipe 52 to liquefy organic matter. The solvent is collected all in the handwritten 54 placed on the lower side thereof.
그리고 활성탄 흡착관(70)은 직경70mm, 길이 350mm의 플라스틱 튜브로 구성되어 그 내측으로 야자각(cocount shell)계 파쇄형 용매회수용(solvent recovery)급 활성탄소가 가득 채워지는 구성으로 되어 있다.The activated carbon adsorption tube 70 is composed of a plastic tube having a diameter of 70 mm and a length of 350 mm, and is filled with a coconut shell-based crushed solvent recovery grade activated carbon.
진공펌프(60)는 다이아프램식 진공펌프(diaphragm type vacuum pump)로 구성되어 실효배기속도(actual pumping speed): 55ℓ/min, 도달압력(ultimate pressure): 3320㎩(pascal) 이다.Vacuum pump 60 is composed of a diaphragm type vacuum pump (actual pumping speed): 55 l / min, the ultimate pressure (ultimate pressure): 3320 kPa (pascal).
그리고 2차냉각기(50)는 이외에도 진공조절을 위해 제어밸브(55)와 진공측정을 위한 압력계(57) 및 배기속도 측정을 위한 유량계(56)가 구비되어 있다.In addition, the secondary cooler 50 is provided with a control valve 55 for controlling the vacuum, a pressure gauge 57 for measuring the vacuum, and a flow meter 56 for measuring the exhaust velocity.
이와 같이 구성 결합된 본 고안은 실험실에서 회전진공증발농축기(20)를 사용하여 추출 및 농축을 진행하는 과정에서 순환식저온항온수조(40)로부터 냉각수를 공급받아 회전진공증발농축기(20)에 부설되는 냉각관(30)에서 유기용매가스를 냉각, 액화하여 회수병(10)에 회수하는 것은 종래와 동일하게 이루어진다.This design combined with this configuration is supplied to the rotary vacuum evaporator 20 by receiving the cooling water from the circulating low temperature constant temperature water bath 40 in the process of extracting and concentrating using the rotary vacuum evaporator 20 in the laboratory. The organic solvent gas is cooled and liquefied in the cooling tube 30 to be recovered to the recovery bottle 10 in the same manner as in the prior art.
다만, 본 고안은 상기한 회전진공증발농축기(20)에서 완전히 냉각, 액화되지 아니한 유기용매가스를 다시 2차냉각기(50)측으로 순환시킨다.However, the present invention circulates the organic solvent gas that is not completely cooled and liquefied in the rotary vacuum evaporator 20 to the secondary cooler 50.
그리하면 회전진공증발농축기(20)에 의해 충분히 냉각 액화되지 않은 유기용매가스는 2차냉각기(50)의 냉각관(52)에 의해 다시 한번 냉각, 액화과정을 반복하게 되고 냉각관(52)에 의해 액화된 유기용매는 수기(54)에 모으게 된다.Then, the organic solvent gas that has not been sufficiently cooled and liquefied by the rotary vacuum evaporator 20 is repeatedly cooled and liquefied by the cooling tube 52 of the secondary cooler 50, and the cooling tube 52 The organic solvent liquefied by this is collected in the handwriting 54.

Solvent gas can prevent air pollution in the laboratory.
이상에서 설명한 바와 같이 본 고안에 의하면, 실험실내에서 추출 및 농축과정에서 사용하는 회전진공증발농축기에 의해 액화되지 않은 유기용매가스는 2차냉각기를 이용하여 다시 한번 냉각, 액화를 반복시킴으로써 유기용매가스의 제거 효율을 높일 수 있는 것이다.As described above, according to the present invention, the organic solvent gas, which is not liquefied by the rotary vacuum evaporator used in the extraction and concentration process in the laboratory, is repeatedly cooled and liquefied by using a secondary cooler. It is possible to increase the removal efficiency.
그리고 2차냉각기에서도 액화되지 아니한 미량의 유기용매가스는 활성탄소가 가득 채워진 활성탄 흡착관을 이용하여 완전히 제거함으로써 종래처럼 유기용매가스가 실험실내로 확산되어 공기를 오염시키는 것을 방지할 수 있게 된다.In addition, a small amount of organic solvent gas that is not liquefied in the secondary cooler is completely removed by using an activated carbon adsorption tube filled with activated carbon, thereby preventing organic solvent gas from being diffused into a laboratory and contaminating air.
그리고 농축 및 증발기의 냉각성능을 높이므로써 유기용매가스 추출효율이 크게 향상되는 등의 작용 효과를 가지는 매우 유용한 고안인 것이다.And by increasing the cooling performance of the concentration and evaporator is a very useful design having an effect such as greatly improving the organic solvent gas extraction efficiency.
