Method for preventing smoke of converter from polluting environment

Abstract

The invention provides a method for preventing smoke of a converter from polluting the environment. The method comprises the following steps: arranging at least four spray nozzles on the periphery of a fire hole and dividing the spray nozzles into two groups, wherein one group of the spray nozzles are positioned at the 1 / 4 radius in the front of the converter while the other group of the spray nozzles are positioned at the rest 3 / 4 radius; arranging a blowing process abnormal smoke purifying button for controlling all the spray nozzles on a master control chamber; arranging an iron charging furnace gas purifying button which controls the 1 / 4 spray nozzles in the front of the converter on an iron charging room in the front of the converter; arranging a steel tapping smoke purifying button which controls the rest 3 / 4 spray nozzles on a steel tapping operation table; starting the iron charging furnace gas purifying button during iron charging; starting the blowing process abnormal smoke purifying button when splashing is about to be caused or has been caused in a smelting process; and starting the steel tapping smoke purifying button or the blowing process abnormal smoke purifying button during tapping of duplex front half steel of the converter. By the method, converter smoke can be effectively suppressed and purified, pollution of harmful smoke to the air and the environment of the inside and the outside of a factory is reduced greatly, the production and working environment and the air quality are improved, and health of staff and nearby residents is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of steelmaking environment protection, and in particular relates to a method for preventing environmental pollution by smoke and dust in the process of converting iron into a converter, splashing in blowing or tapping the first half of steel. Background technique [0002] When the converter is mixing iron, it is inevitable that part of the molten iron will scrape against the furnace mouth, resulting in a large amount of smoke and dust gas. At the same time, during the blowing process of the converter, various physical and chemical reactions are violently going on in the converter. If these reactions are not particularly effectively controlled, there will be slag overflow or even splashing and explosion phenomena. It is a continuous large production container, and it is basically impossible to completely avoid the splash and explosion during the blowing process. In the event of splashing and blasting, the ga...

At the same time, during the blowing process of the converter, various physical and chemical reactions are violently going on in the converter. If these reactions are not particularly effectively controlled, there will be slag overflow or even splashing and explosion phenomena. It is a continuous large-scale production container, and it is basically impossible to completely avoid the splash and explosion during the blowing process.
