Smelting Furnace Dust Collector
Smelting Furnace Dust Collector
First, Technological Process of Dust Removal System
1, Generally Adopted Technological Process
The technological process for one—time smoke exhaust in electric furnace, secondary smoke exhaust in enclosed cover of electric furnace and proof of factory workshop, smoke exhaust in refining furnace and feeding system, flue gas collection combined with the main pipe of the electric furnace dust removal system under pressure of fan, dry dust removal method of filter bag filtration, and the technological process of negative pressure operation.
2, PLC Automatic Control
Pulse (set time or pressure difference) blowing ash back.
According to the smelting conditions, the air volume, wind pressure and fan power of each dust collecting point are automatically adjusted.
Second, Key Technical Problems
1, Quality of Filter Material for Dust Collector Cloth Bag
The quality selection of filter materials determines the operation resistance, operation cost and investment cost of dust collector, and directly affects the emission concentration of smoke and dust.
2, Ash Cleaning Technology
The ash cleaning performance directly affects the filtration efficiency and the life of cloth bag.
3, Flue—gas Temperature
Smoke temperature control directly affects the smoke exhaust effect of enclosed cover and roof of factory workshop, the formation of micro negative pressure in furnace and the life of cloth bag.
