Abstract

The invention discloses an automatic dredging system and method for a converter vaporization flue sampling hole. The automatic dredging system comprises a valve group control pipeline, a dredging device control pipeline, a sampling hole control valve group, a dredging device (6) and a control assembly. One end of the valve group control pipeline is connected with a nitrogen input pipeline, and the other end of the valve group control pipeline is connected with the sampling hole control valve group. One end of the dredging device control pipeline is connected with the nitrogen input pipeline, the other end of the dredging device control pipeline is connected with the dredging device (6), the dredging device (6) is opposite to the sampling hole control valve group in position, the sampling hole control valve group is connected with the converter vaporization flue sampling hole, and the dredging device (6), the sampling hole control valve group and the converter vaporization flue sampling hole are located on the same axis. The valve group control pipeline, the dredging device control pipeline and the nitrogen input pipeline are electrically connected with the control assembly.

Description

technical field [0001] The invention belongs to the technical field of dredging of a converter vaporization flue, and in particular relates to an automatic dredging system and a dredging 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 ...
