본 출원은 2017년 11월 24일에 출원된 한국특허출원 제10-2017-0158760호에 기초한 우선권을 주장하며, 해당 출원의 명세서 및 도면에 개시된 모든 내용은 본 출원에 원용된다.The present application claims priority based on Korean Patent Application No. 10-2017-0158760, filed on November 24, 2017, the entire contents of which are incorporated herein by reference.
일반적으로, 약품을 개발하거나 시험하는 실험실에는 유해가스 등의 위험물질로부터 작업자의 안전을 보장하기 위한 환기 및 공조시스템 등이 구축되어 있으며, 이와 더불어 실험실의 내부에 위험물질이 작업자에게 접촉되지 않도록 하는 안전장치로써 시험이 이루어지는 공간의 기체를 실외로 강제 배출시키는 흄후드(Fume Hoods)가 설치되어 있다.Generally, ventilation and air conditioning systems are installed in laboratories that develop or test chemicals to ensure the safety of workers from dangerous substances such as harmful gases. In addition, As a safety device, fume hoods are installed to forcibly discharge the gas in the space where the test is performed outdoors.
이러한 흄후드는 전면에 내부를 볼 수 있도록 유리로 된 도어가 상하로 슬라이딩 가능하게 설치되고, 내측에 각종 시험을 할 수 있는 적당한 공간을 갖춘 챔버가 구비되며, 챔버의 상부에 시험과정에서 발생하는 유해물질을 포집하여 강제로 배기시키기 위해 배기장치와 연결되는 배기부가 구비된다.In this fume hood, a glass door is installed so as to be able to slide in the up and down direction so as to see the inside of the fume hood, and a chamber having a proper space for various tests is provided inside. And an exhaust unit connected to the exhaust device for collecting and forcibly discharging harmful substances.
이에 따라, 작업자가 흄후드의 도어를 밀어올려 챔버를 개방시킨 상태에서 각종 시험기구를 이용하여 시험을 할 경우, 흄후드는 시험과정에서 발생되는 유해가스를 음압이 작용하는 배기부을 통해 실외로 강제 배기시키게 되고, 오염물질이 실험실에 축적되거나 작업자에게 노출되지 않도록 차단하게 된다.Accordingly, when the operator pushes the door of the fume hood up to open the chamber and performs testing using various test instruments, the fume hood is forced through the exhaust part where the negative pressure is generated, And the pollutants are prevented from accumulating in the laboratory or being exposed to workers.
그러나, 종래의 흄후드는 내부에서 정화된 유해가스가 외부로 배출되는 경우, 실험공간부의 대기 압력이 낮아지고, 실험공간부의 대기압을 유지시키기 위해 실험공간부로 미세먼지 등을 포함한 외부 기체가 유입되는 문제점이 발생한다.However, in the conventional fume hood, when the purified harmful gas is discharged to the outside, the atmospheric pressure of the experimental space is lowered and an external gas including fine dust is introduced into the experimental space to maintain the atmospheric pressure of the experimental space A problem arises.
즉, 정밀한 실험데이터를 획득하기 위해서는 실험공간부 환경이 일정하게 유지되어야 하는데, 외부 기체가 포함하고 있는 미세먼지 등의 다른 성분들로 인해 실험결과에 지장을 초래하는 문제점이 발생된다.In other words, in order to obtain precise experimental data, the environment of the experimental space must be maintained constantly. However, there arises a problem that the experimental results are hindered due to other components such as fine dust contained in the external gas.
따라서, 실험공간부의 대기압을 균일하게 유지시킬 수 있도록 정화된 기체를 순환시키고, 유해실험물질에서 생성되는 유해가스를 효과적으로 정화시켜 배출할 수 있는 흄후드의 개발이 필요한 실정이다.Therefore, it is necessary to develop a fume hood that can circulate the purified gas so that the atmospheric pressure of the experimental space can be uniformly maintained, and effectively purify and discharge the harmful gas generated from the hazardous test material.
이에 본 발명은 전술한 배경에서 안출된 것으로, 실험공간부의 오염된 기체가 배기덕트에 설치된 세척모듈과 기액접촉모듈을 통해 정화되어 강제 배출되도록 함으로써, 작업자의 안전을 확보할 수 있고, 필터모듈을 통해 정화된 기체가 실험공간부로 유입되도록 함으로써, 청정 환경속에서 작업을 수행할 수 있는 흄후드를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made in view of the above background, and it is an object of the present invention to provide a filter module in which a polluted gas in an experimental space is purified and discharged through a cleaning module and a gas-liquid contact module installed in an exhaust duct, The present invention provides a fume hood capable of performing a work in a clean environment by allowing a purified gas to flow into an experimental space.
또한, 실험공간부의 오염된 기체가 정화되어 강제 배출되도록 하는 배기턱트와, 정화된 기체가 실험공간부로 유입되도록 하는 기체이동통로가 분리되어 기체의 흐름을 유도함으로써, 오염된 기체와 정화된 기체가 실험공간부로 혼입되는 것을 방지할 수 있는 흄후드를 제공하는데 그 목적이 있다.In addition, an exhaust tube for purifying the contaminated gas in the test space and forcibly discharging the gas is separated from the gas transfer passage for allowing the purified gas to flow into the test space, whereby the contaminated gas and the purified gas And it is an object of the present invention to provide a fume hood which can prevent the fume hood from being mixed into an experimental space portion.
또한, 실험공간부의 오염된 기체가 정화되어 강제 배출시 기체이동통로를 통해 미량의 기체가 실험공간부로 유입됨으로써, 오염된 기체가 기체이동통로로 유입되는 것을 방지할 수 있는 흄후드를 제공하는데 그 목적이 있다.The present invention also provides a fume hood capable of preventing a contaminated gas from flowing into a gas moving passage by flowing a small amount of gas into a test space through a gas moving passage at the time of forced discharge, There is a purpose.
