Design ideas for smelting furnace flue gas purification. The pulse Bag Type Dust Collector is used as the flue gas purification equipment. From the flue dust composition of the corundum smelting furnace, it can be seen that the content of Al2O3 and SiO2 in the ash accounts for 82.63% of the total dust. In this case, the specific resistance of the dust is too high. If the dust is collected by an electrostatic precipitator, a reverse corona phenomenon will occur and the dust collection efficiency is not high. At the same time, due to the small particle size of the dust, the dust less than 5Lm accounts for a large proportion The specific gravity is only 0.5t / m3, and the secondary dust will be generated when the electrostatic precipitator vibrates and cleans the dust, which causes the dust collection efficiency to decrease. This shows that it is not appropriate to use electric Dust Collectors as flue gas purification equipment. The fact that the actual operating effect of the 3000kVA corundum smelting furnace ESP in a certain plant is not obvious also confirms this.
The bag-type dust collector is not affected by the specific resistance of dust, and has a very high collection rate for dust with small particle size. It is an ideal dust removal equipment for purifying corundum smelting furnace. In practical projects, bag-type dust collectors are also mostly used, and the dust collection effect is good, and the dust emission concentration can be controlled within 50 mg / m3. According to the characteristics of fine and sticky dust in corundum smelting furnace, the resistance of bag dust collector equipment can be controlled within the set range only by strong dust cleaning method. It is an indisputable fact that the pulse bag type dust collector has strong dust removal ability, and its dust removal ability is much higher than that of the weak dust removal such as back blowing. It has become the first choice for many furnace kiln flue gas purification equipment. CD series long bag low pressure pulse bag type dust collector and other new generation pulse bag type dust removal technology occupy less area, low equipment resistance, low air pressure required for cleaning, low energy consumption, reliable work, small maintenance workload, etc. It eliminates the phenomenon that the resistance of the weak dust-cleaning bag type dust collector is too high, and it is increasingly used in various industrial sectors.
