Description

technical field [0001] The invention belongs to the technical field of converter vaporization flue blockage removal, and in particular relates to an automatic blockage removal system and method for a sampling hole of a converter vaporization flue. Background technique [0002] Oxygen converter steelmaking flue gas is one of the main air pollutants produced in the production process of the converter steelmaking industry. The coal gas and iron-containing dust in the converter flue gas must be recovered and utilized. Since the temperature of the converter steelmaking flue gas is as high as 1600 degrees, The first process after the converter flue gas is generated is to use the vaporization cooling flue to cool down, and at the same time to recover the steam generated by heat exchange. In order to increase the amount of gas recovery and effectively and accurately control the speed of the fan in the system, devices such as pressure sensing are often installed on the flue. Due to ...
