Abstract

The invention relates to the technical field of converter dedusting, and especially relates to a dedusting system and a dedusting method used for improving the effect of wet dedusting. According to the system, more than one dedusting dehydration tank body is connected in series behind a blower on the pipe of a wet dedusting system. A cylindrical structure with tapered diameter is arranged in the inlet pipe of the dedusting dehydration tank body. Mist spray guns are respectively arranged in front of the inlet of the cylindrical structure and behind the outlet of the cylindrical structure. The dedusting dehydration tank body is arranged vertically. A cyclone channel, a baffle channel and a filtering dedusting device are arranged in the dedusting dehydration tank body. Flue gas is discharged from a dedusting blower, processed through compression, spraying, speed reduction, cyclone, baffling and filtering, and is discharged to a chimney. According to the invention, the wet dedusting technology is utilized, and investment is low. With the system and the method, fume purification dust content can be reduced to below 30mg / Nm<3>, such that a national standard is met. The system and the method have instructive significance for enterprises having difficulties in changing wet dedusting into dry dedusting.

Description

technical field [0001] The invention relates to the technical field of converter dedusting, in particular to a dedusting system and method for improving the effect of wet dedusting. Background technique [0002] China's iron and steel industry is in a period of structural adjustment, optimization and upgrading, and is facing increasingly severe resource and environmental pressures. With the deteriorating air environment and the increase of smog days all over the country, the environmental protection department has put forward stricter requirements on the emission standards of the steel industry. All of these make the iron and steel industry must take the road of resource-saving, green and sustainable development. Therefore, reducing the smoke and dust emissions of converters is of great significance for reducing environmental pollution and improving air quality. [0003] At present, the converter primary dedusting system mainly includes wet dedusting (OG dedusting), dry ded...
