A
ferromolybdenum smelting smoke and gas dry method dust collection technics, which solves the problems that the existing wet method dust collection has low dust collection efficiency, the
smoke and gas can't meet the environment protection requirements, the
system runs unstably, take serious
erosion to the fan and the pipeline equipment and the recycled material is not easy to store. The method is that: the
smoke and gas produced by
ferromolybdenum smelting furnace enters into a U-shaped cooling
machine to lower temperature naturally by a gas skirt, and proceed dust collection by a bag dedusting
machine and is discharged reaching the standard; the dust material collected by the bag falls into the dust hopper of the bag dust collection
machine by pulse spraying and blowing, which is used for
smelting to produce
ferromolybdenum, the smoke and gas after dust collection is transferred into a
chimney to
discharge out. The advantages of the invention are that: the invention has low investment and small running expense, which is economic with obvious environment benefit, and has quick capital payoff, the material recycle efficiency can reach above 99.9 per cent; the discharged smoke and gas can meet the requirement of protecting environment; the management is convenient, the operation is simple and the running is stable; the
erosion to the fan and the pipeline equipment is small, which prolongs the service life of the equipment; the dry power material can be recycled directly, and is easy to lay; the process
mating is easy, the engineer occupies small space and is easy to arrange.
