Process of dust removal system for steel plant dust removal equipment:

The dust removal system of a 100t DC electric arc furnace adopts a combined smoke exhaust method of in furnace smoke exhaust and out of furnace smoke exhaust. The smoke exhaust outside the furnace consists of a sealed hood and a roof hood, which are switched between use. The roof hood is mainly used in the feeding and steelmaking processes, while the large sealed hood is mainly used in the smelting process. The dust removal system mainly consists of smoke exhaust device, water-cooled dense exhaust pipe, forced blowing cooler, internal smoke exhaust fan, long bag low-pressure large pulse bag dust removal equipment, buried scraper conveyor, bucket elevator, ash storage bin, and main smoke exhaust air

At present, the treatment of electric furnace dust in China generally adopts LCM long bag low-voltage large pulse bag dust removal equipment. Based on the fine and sticky characteristics of electric furnace dust, in order to ensure the normal operation of bag dust removal equipment at an appropriate resistance level, bag dust removal equipment is required to have strong dust cleaning ability. Therefore, LCM long bag low-voltage large pulse bag dust removal equipment is selected as the dust removal equipment. This equipment has been widely used in industries such as electric furnace steelmaking, blast furnace coal injection, sintering, refractory, carbon black, cement, etc., and has achieved good results.

Its main characteristics are as follows:

Strong dust cleaning ability. Its dust cleaning strength (usually measured in g=9.8m/s2) can reach 60-200g, while the back blowing or mechanical vibration bag filter only has 3-5g or 10g, respectively. Therefore, even for fine and sticky dust, it can achieve good dust cleaning effect. High filtration load. For the treatment of electric furnace smoke and dust, the filtration wind speed can reach 1.5m/min. The filter bag is up to 6m long, which is 2-3 times longer than traditional pulse bag dust removal equipment, thus occupying a small area. The length of the filter bag depends on its strong dust cleaning ability, and it will not affect the dust cleaning effect due to the lengthening of the filter bag.
