Difficulties of dust removal in plasma cutting of spiral steel pipe

At present, the most common pipe cutting method for spiral steel pipe manufacturers is plasma cutting, which will generate a large amount of metal vapor, ozone, and nitrogen oxide smoke during cutting, which will seriously pollute the surrounding environment. The key to solving the soot problem is how to inhale all the plasma soot into the dust removal equipment, to prevent air pollution.

1. The cold air around the suction port enters the suction port from outside the machining gap and the air volume is large so that the total amount of smoke and cold air in the steel pipe is greater than the effective air volume inhaled by the dust collector, so it becomes impossible to completely absorb the cutting smoke and dust.

2. When the nozzle of the plasma gun is cutting, the air is blown out in two opposite directions at the same time, so that the smoke and dust emerge from both ends of the steel pipe, and the suction port is installed in one direction of the steel pipe is difficult to recover the smoke and dust well.

3. Since the cutting part is far away from the dust suction inlet, it is difficult for the wind to reach the suction inlet to draw the smoke and dust.
