Converter dust removal is one of the very important environmental protection measures in the steel smelting process. Generally speaking, converter dust removal can be divided into two parts: secondary dust removal and tertiary dust removal.

First, let's look at the second dust. Secondary dedusting is to set up dedusting equipment above the converter body, and the flue gas at the top of the converter is extracted into the dedusting equipment for filtration through the exhaust fan. The main function of secondary dust removal is to remove dust from slag and furnace dust, thereby reducing environmental pollution. In dust removal equipment, bag filters or electrostatic precipitators are usually used to filter dust particles in flue gas, so that flue gas emissions meet environmental requirements. The effect of dust removal equipment mainly depends on the design of the dust collector and the reasonable setting of operating parameters.

Second, we look at three dust. The third dust removal refers to the further removal of fine particles in the flue gas after the second dust removal through further treatment, so as to make the flue gas emission cleaner. Tertiary dust removal is usually treated with a wet electrostatic precipitator (WESP). In the wet electrostatic precipitator, the flue gas passes through the cooling and humidification device to combine the particulate matter in the flue gas with the water vapor to form a particulate water mist, and then through the action of the high-voltage electric field, the fine particulate matter in the particulate water mist is electrically removed, and finally Clean flue gas. The effect of tertiary dust removal mainly depends on the design of the wet electrostatic precipitator and the reasonable setting of operating parameters.

Through the treatment of secondary dust removal and tertiary dust removal, the dust particles in the converter slag and furnace dust can be removed, thereby reducing the pollution to the environment. At the same time, the clean flue gas can be further recycled, reducing the waste of resources. The application of converter dust removal technology not only helps to protect the environment, but also helps to improve the energy utilization efficiency and product quality in the steel production process.

In short, converter dust removal is a very important environmental protection measure in the steel smelting process. Through the treatment of secondary dust removal and tertiary dust removal, dust particles in slag and furnace dust can be effectively removed, and environmental pollution can be reduced. The application of converter dust removal technology not only helps to protect the environment, but also helps to improve energy efficiency and product quality.
