Background
The strip steel is pickled to remove the oxide scale on the surface of the strip steel, so that the strip steel has a clean and smooth surface, and the surface quality of the strip steel is improved. In the pickling tank, the strip steel and the acid liquor undergo a severe chemical reaction, the hydrochloric acid with high temperature and high concentration reacts with ferric oxide on the surface of the strip steel to remove the ferric oxide, but if the pickling is excessive, the hydrochloric acid further reacts with the metallic iron under the ferric oxide to generate hydrogen.
The hydrogen is a common gas product in the pickling tank, and low-concentration hydrogen can be discharged out of the tank body without causing harm if the low-concentration hydrogen can be discharged, but because the air outlet of the pickling tank is generally arranged on the side face, the low-density hydrogen is often accumulated at the top of the tank body, the sucking capacity of an air exhaust system for the hydrogen is limited, and the hydrogen in the tank body can be greatly enriched at the top of the tank body and the area which cannot be influenced by the air exhaust system. As the hydrogen concentration increases, the likelihood of hydrogen explosion of the pickling tank increases.
