Abstract

The invention discloses a drainage device of a converter gas analyzer, belonging to the technical field of a converter gas analyzer in the metallurgical industry. The drainage device comprises a steam-water separator and a sample gas filter, wherein a gas inlet of the steam-water separator is communicated with a sample gas inlet with a valve through a pipeline; a water outlet of the steam-water separator is connected with a separator drainage pipeline with a drainage valve; a gas outlet of the steam-water separator is communicated with an inlet of the sample gas filter through a vent pipeline; a vent valve communicated with the atmosphere is arranged on the vent pipeline; and the bottom of the sample gas filter is communicated with a water inlet end of the drainage valve on the separator drainage pipeline through a filter drainage pipeline. The drainage device disclosed by the invention is simple and compact in structure and does not generate pressure difference and consequent failure of drainage during drainage; and moreover, the drainage device realizes efficient and sufficient drainage, does not need artificial drainage and is favorable for saving the production cost.

Description

technical field [0001] The invention relates to the technical field of converter gas analyzers in the metallurgical industry. Background technique [0002] The transformation of the iron and steel industry from energy conservation and cleanliness to a circular economy model is the inevitable result of the rapid development of the iron and steel industry in recent years. The realization of negative energy steelmaking in converter production has the advantages of reducing costs and realizing energy recycling. Recycling converter gas realizes negative energy steelmaking It has been widely used in converter steelmaking plants at home and abroad. [0003] The gas analyzer mainly detects CO and O in converter gas 2 According to the analysis results of the analyzer, it is decided whether to recover or disperse the gas. The gas analyzer takes samples from the converter gas pipeline for analysis through the sampling pipeline. The dust content in the converter gas is large, and the ...
