Abstract
The utility model discloses a non-methane total hydrocarbon detection device, which comprises a first mounting chamber, a second mounting chamber, a gas chromatograph, a gas detector and a gas detector, and is characterized in that the gas chromatograph is arranged in the first mounting chamber and is used for carrying out qualitative and quantitative analysis on a multi-component mixture; the second mounting chamber is internally provided with a hydrogen-air all-in-one machine, and the hydrogen-air all-in-one machine is connected with the gas chromatograph through a pipeline and provides hydrogen and air for a detector in the gas chromatograph; the third mounting chamber is internally provided with a pretreatment system, and the pretreatment system is connected with the gas chromatograph through a pipeline and provides driving gas and a positive pressure gas source for the gas chromatograph. According to the scheme, the gas chromatograph, the hydrogen-air all-in-one machine and the pretreatment system are respectively integrated in the independent mounting chambers in the detection device, so that the integration level is effectively improved. In addition, the gas chromatograph is arranged in the independent box body, so that the explosion-proof requirement of explosive places such as petrochemical engineering can be directly met without an external explosion-proof cabin.
