The invention discloses an analysis system of gas oxygen content. The analysis system of gas oxygen content comprises a gas pipeline for providing the gas, a sampling pipe connected with the gas pipeline, an oxygen content analyzer connected with the sampling pipe, and a steam pipeline connected with the sampling pipe; the gas pipeline provides the gas; the gas is sampled by the sampling pipe andanalyzed by the oxygen content analyzer; when the sampling pipe needs to be blown and swept, the sampling pipe stops sampling; and, the steam pipeline provides the steam, is opposite to the sampling direction of the gas, and blows and sweeps the sampling pipe by the reverse flow. The analysis system of gas oxygen content provided by the invention is provided with the steam pipeline, so as to blowand sweep the sampling pipe by the reverse flow; if any impurity exists in the sampling pipe, the impurity can be blown away from the sampling pipe by the reverse flow sweep of the steam pipeline; theblocking of the sampling pipe is reduced; the normal sampling and the precise monitoring can be ensured; and thus, the gas pressure station and the downstream gas device can produce safely.
Description
technical field [0001] The invention relates to the technical field of gas analysis, in particular to an analysis system for the oxygen content of gas. Background technique [0002] The gas pressurization station mainly uses the surplus coke oven gas or hydrogen desorption gas from the coking unit as raw material, buffers and mixes the gas through the gas cabinet, and transports the mixed gas as gas to the downstream gas-consuming device, so as to realize circular economy and reduce exhaust gas emissions. [0003] Since the gas is a mixed gas, the oxygen content may be unstable. Therefore, the oxygen content of the gas is a core parameter. Whether it can be accurately monitored will directly affect the safe and stable operation of the gas pressurization station and downstream gas-consuming devices. The oxygen analyzer conducts sampling and analysis, but the gas often contains impurities such as hydrogen sulfide, tar, naphthalene, etc. During long-term monitoring, the impurit...
