Abstract

The invention discloses a gas sample feeding device for determining total organic carbon of a stationary pollution source and an application system of the gas sample feeding device. The gas sample feeding device comprises a connecting seat, a fixed cap and a sealing gasket, wherein the fixed cap is connected to the connecting seat, and the sealing gasket is arranged between the connecting seat and the fixed cap; the connecting seat comprises a concave table and a hollow air passage, the concave table extends downwards from the center of the top end of the connecting seat, and the hollow air passage extends downwards from the center of the bottom surface of the concave table to penetrate through the connecting seat; the sealing gasket is arranged on the bottom surface of the concave table to close the hollow air passage; and the fixed cap comprises a connecting part and a holding part, the connecting part is located at the lower part, the holding part is located at the upper part, the connecting part is inserted into the concave table, and the holding part protrudes out of the top end of the connecting seat. According to the gas sample feeding device, the sealing property of gas transmission, the fluidity of an air way and the measurement precision are effectively guaranteed, the total organic carbon in the stationary pollution source of gas can be directly determined, and gas can smoothly flow into a pipeline in an instrument and finally reaches an NDIR detector.

Description

technical field [0001] The invention belongs to the field of gas pollutant discharge detection and monitoring, and in particular relates to a gas detection device and an application system for measuring the content of organic matter in waste gas from fixed pollution sources. Background technique [0002] At present, the emission control indicators of air pollutants mainly include non-methane hydrocarbons, benzene series, and total volatile organic compounds. In the monitoring of exhaust gas from fixed pollution sources at home and abroad, the main method for determining total gaseous organic compounds is the determination of non-methane total hydrocarbons. Gas chromatography, this method uses gas chromatography to measure total hydrocarbons and non-methane hydrocarbons, and the difference between the two is used as the content of non-methane hydrocarbons. However, due to the different responses of the flame ionization detector (FID) of gas chromatography to different organic...
