Metallurgical Dust filter dust collector for Lead, Copper, and Zinc smelter

Metallurgical Dust filter dust collector for Lead, Copper, and Zinc smelter

1. Product introduction 

The dust collecting system includes water spraying cooling tower, surface cooler, bag-type dust collector, dust collection fan and gas pipeline. Normally the smoke quantity from rotary furnace is *m3/h with 900-1100℃temperature under normal pressure. There are certain SO₂ content. Its dust content is *g/m3. (* can be calculated according to customer’s raw material specification and capacity).

The high temperature smoke will enter water spraying tower through pipeline, through which the temperature of smoke will be lower to 500℃. Then the smoke from cooling tower enter 360m² surface cooler with its temperature lower to ≤200℃. And then the smoke goes into bag-type dust collector. The smoke filtered by the dust collector will be discharge from chimney by dust collection fan. As the rotary furnace smelting is not continuous operation and its SO₂ content is very low, whether a absorption tower is required should according to Algeria regulations.

3. Surface cooler specification

Surface cooler consist of stand column, box, ash bucket, heat dissipation pipeline, air inlet, air outlet, and so on. The high temperature smoke enter the cooler box through the air inlet. The box also functions as a gravity settling chamber. The big particle dust will fall down into ash bucket due to gravity and be collected and discharged by a unloader. The high temperature smoke will have heat exchange with air in the heat dissipation pipeline and then discharged from the air outlet.

4 Water spraying cooling tower specifications

Water spraying cooling tower consist of stand column, shell, ash bucket, cold water pipeline, air inlet, air outlet, and so on. High temperature smoke will enter the cooler shell. The shell also functions as a gravity settling chamber. The big particle dust will fall down into ash bucket due to gravity and be collected and discharged by a unloader. The high temperature smoke will have heat exchange with the cold water pipeline in the shell. The circulation water in the pipeline will bring away part of heat. And then the smoke will be discharged from the water cooling tower air outlet.
