Embodiment 1

[0013] Such as figure 1 As shown, a combined coalbed methane sampling and analysis device consists of three parts: on-site detection part, on-site sampling part and tail gas discharge part. 2 phases are connected to collect coalbed methane for detection. After the on-site detection part is tested, it is connected to the tail gas discharge part through the pipeline. The on-site sampling part is connected to the buffer tank 2 through the sampling pipeline to collect coalbed methane for sampling. The on-site sampling part is completed Afterwards, the pipeline is connected with the tail gas discharge part, and the on-site detection part includes a decompression device 3, a temperature sensor 4, a dew point sensor 5, a pressure sensor 6 and a methane analyzer 7, and the methane analyzer 7 passes through the detection pipeline and the buffer tank 2 phase connection, a decompression device 3 is provided on the side of the detection pipeline close to the buffer tank 2, and a temperatu...

Abstract

The invention belongs to the technical field of gas detection devices, and particularly relates to a coalbed methane sampling and analysis joint device, which aims at solving the problems of difficulty in quality tracking and failure to operate at site in the existing coalbed methane high-pressure detection process. The coalbed methane sampling and analysis joint device comprises a site detection part, a site sampling part, and a tail gas exhaust part, wherein coalbed methane is sent into a buffer tank through a pipeline; the site detection part is connected with the buffer tank through a detection pipeline to collect the coalbed methane to detect; after the detection is completed, the site detection part is connected with the tail gas exhaust part through a pipeline; the site sampling part is connected with the buffer tank through a sampling pipeline to collect the coal gas bed to sample; after the sampling is completed, the site sampling part is connected with the tail gas exhaust part through a pipeline.

Description

technical field [0001] The invention belongs to the technical field of gas detection devices, and in particular relates to a coalbed gas sampling and analysis combined device. Background technique [0002] With the continuous reduction of global energy, the utilization of gas such as coal bed methane and natural gas will account for an increasing proportion in the field of energy use. As a high-quality energy source, gas has been widely used in many fields such as chemical industry, civil use, and industry. However, due to the high pressure of coalbed methane, sampling is difficult, and due to the particularity of gas as a gas product, it is difficult to measure the temperature and pressure data at the sampling site, which poses difficulties for subsequent accurate calculation and quality traceability. Although there are laboratory methods for analysis and testing, accurate on-site data are required to provide correct test reports. It is of great practical significance to d...
