Abstract

In a related art, since a problem such as condensation of some components of a gas sample collected from a chimney or the like occurred, precise analysis was difficult. However, the present invention, as technology development of a structural design which solves these problems, is a technology which enables accurate analysis by maintaining a temperature above a predetermined temperature of a collection sample and analyzing a sample in a uniform gas status when the collection sample is sent to an analysis site. A pre-treatment apparatus for precise gas samples comprises: a sampling pipes; a chamber; a heating means; a control unit; and an outlet pipe.

배기 가스로부터 추출된 기체상의 시료에 대한 본격적인 분석에 앞서 뷴석 대상 유체를 분석에 적합한 조건으로 초리하기 위한 분석 전처리 장치에 관한 것이다.It relates to an analytical pre-processing device for isolating the fluid to be undiluted under conditions suitable for analysis prior to full-scale analysis of a gaseous sample extracted from exhaust gas.

굴뚝을 통해 대기중으로 방출되는 배기 가스의 정확한 분석을 위하여, 채취된 시료가 분석 사이트에 유입되기 전에 해당 시료를 적절한 물리, 화학적 상태로 처리하기 위한 장치를 제공하는 것을 이루려고 한다.In order to accurately analyze the exhaust gas emitted into the atmosphere through a chimney, an attempt is made to provide a device for processing the sample in an appropriate physical and chemical state before it is introduced into the analysis site.

굴뚝을 통해 대기중으로 방출되는 배기 가스에 있어 먼저 굴뚝 내부에 시료채취 파이프를 삽입하고, 일정한 내부 공간을 구비하여 이 공간이 시료 채취 파이프를 통해 배기 굴뚝 내부와 연통 되도록 파이프 타단에 연결된 체임버와, 체임버 내부의 온도를 감지할 수 있는 온도 센서, 체임버 내부 공간에 열을 전달할 수 있도록 장착되는 가열 수단과, 이에 연결되어 온도 센서로부터 감지된 신호에 따라 가열 수단에 작동 신호를 인하하여 체임버 내부 공간의 온도를 조절하는 제어부 및 체임버 내의 유체를 외부로 유출시킬 수 있는 유출관을 포함하여 구성 한다.In the exhaust gas discharged to the atmosphere through the chimney, a sampling pipe is first inserted into the chimney, and a chamber connected to the other end of the pipe is provided with a constant internal space so that this space communicates with the inside of the exhaust chimney through the sampling pipe. A temperature sensor capable of sensing the temperature inside, a heating means mounted to transfer heat to the chamber interior space, and a temperature of the chamber interior space by lowering an operation signal to the heating means according to a signal detected from the temperature sensor connected thereto. It comprises a control unit for controlling the and the outlet pipe that can discharge the fluid in the chamber to the outside.

종래의 경우 굴뚝 등 채취된 기체 시료는 일부 성분이 응축되는 등의 이유로 정밀한 분석이 어려웠으나, 본 발명에 따른 장치를 거쳐 분석 사이트에서 채취 시료를 보낼 경우 채취 시료의 온도가 일정 온도 이상으로 유지되어 균이한 기체 상태로 시료를 분석할 수 있게 됨으로써 정밀한 분석이 가능해 진다.In the conventional case, the gas sample collected, such as a chimney, was difficult to precisely analyze because some components are condensed, but when the sample is sent from the analysis site through the device according to the present invention, the temperature of the sample is maintained above a certain temperature. By being able to analyze the sample in a uniform gas state, precise analysis is possible.

A temperature sensor capable of sensing the temperature inside the chamber, a heating means mounted to transfer heat to the interior space of the chamber, and connected to it to cut the operating signal to the heating means according to the signal sensed by the temperature sensor, thereby reducing the operating space of the chamber interior space. It comprises a control unit that controls the temperature and an outlet pipe that can discharge the fluid in the chamber to the outside. A filter should be installed on the flow path from the sampling pipe to the chamber. A cylindrical ceramic filter extending from the sampling pipe is used. It must be connected to the air injection device via an air cleaning pipe. The chamber is formed in a tube shape of a metal material having a diameter larger than that of the sampling pipe, and the heating means comprises a heating plate attached to the outer circumferential surface of the metal tube chamber.
