[0002] Electrolytic aluminum is high-purity aluminum obtained by the cryolite-aluminum oxide molten salt electrolysis method. Electrolytic aluminum is mainly used for producing various aluminum processing materials for different purposes. For example, aluminum alloy doors and windows, cigarette foils, aluminum foils used for food packaging, aluminum-plastic composite boards, aluminum electronic foils, etc. are very common in life and are also what electrolytic aluminum is applied to. When electrolytic aluminum is produced, flue gas containing harmful components such as fluorides, a small amount of SO2, and hydrocarbons will be generated, so it needs to be purified.

By circulating and switching the PU pipe joints on both sides, the cleaning effect is better, but it does not have the effect of protecting the detection pipeline. The detection pipeline generally has a small wall thickness and is easily deformed or even damaged under external force impact, affecting the density detection effect, and the density meter is prone to abnormal operation when used in a humid environment.
