Background
After heat treatment of the semifinished steel tube, a hard and brittle iron oxide skin layer is formed on the surface, which must be removed completely before phosphating. At present, most of manufacturers adopt a hydrochloric acid pickling method to remove the layer of iron oxide scale.
The hydrochloric acid mist is mainly generated in the acid washing process, and the formation mechanism of the acid mist is mainly divided into two mechanisms: one is that the surface of the acid solution is evaporated, acid molecules enter the air and are condensed with water in the air to form fog drops; the other is that the acid solution has chemical reaction to form bubbles which float to the liquid surface and then explode to bring out the liquid drops. The acid mist is generally referred to as misty acids. The acid mist in the air has very small particles, is smaller than the water mist particles, has higher humidity than the smoke, has the particle size of 0.1-10 mu m, is a substance between the smoke and the water mist, and has stronger corrosivity.
The emission of acid mist can cause the diffusion of acid mist and acid gas in the air of a workplace, and the acid sedimentation in the atmospheric environment can be caused after the acid mist is emitted into the atmosphere. It not only endangers the health of workers and residents around the factory building, corrodes factory building equipment and precision instruments, causes loss of production and life, but also brings adverse effect to the survival of crops and other animals and plants, causes damage to buildings and the like.
