Abstract

The invention relates to the steelmaking field, in particular to a converter gas ignition diffusing method and a converter gas ignition diffusing control system. Multiple pairs of ignition electrode stems are arranged on a diffusing tower; the space between each pair of ignition electrode stems ranges from 8 mm to 15 mm; and the multiple pairs of ignition electrode stems are connected to positiveand negative electrodes of multiple high-energy igniters correspondingly one to one. When the concentration of carbon monoxide in converter gas is larger than or equal to 20%, the high-energy ignitersconduct high-voltage discharging and ignition, and the converter gas is directly ignited and diffused. The high-energy igniters are adopted to conduct high-voltage discharging to generate heat so that the converter gas can be directly ignited and diffused. Compared with a method that the converter gas needs to be ignited through natural gas and other auxiliary combustible gas in the prior art, the scheme has the beneficial effects that no combustion assisting gas needs to be additionally introduced, and the ignition and diffusion convenience of the converter gas is improved. The problem thatenergy cost is high when long-burning fire such as the natural gas is used for igniting and diffusing the converter gas in the prior art is solved.

Description

technical field [0001] The present application relates to the field of steelmaking, in particular, to a converter gas ignition and release method and a converter gas ignition and release control system. Background technique [0002] During the oxygen blowing smelting process of the converter, the flue gas produced contains a large amount of carbon monoxide, carbon dioxide and a small amount of other gases. Under normal circumstances, these flue gases are dedusted, washed and filtered by the dust removal system. After the gas concentration reaches the standard and the oxygen content meets the requirements, it enters the gas Cabinet recycling. [0003] Before the flue gas enters the dust removal fan, there is a laser detector in the dust removal pipe to detect the content of carbon monoxide and oxygen in the flue gas. When the oxygen concentration is lower than 2% and the carbon monoxide concentration is higher than 25%, the converter gas is eligible for recovery. Converter ga...
