During the alumina production process, pipeline scaling affects production efficiency, especially for pipelines transporting circulating mother liquor. Due to the long-term accumulation of impurities such as sodium carbonate and silicate in the mother liquor, hard scale will form, which is difficult to clean. The scaling substances on the inner wall of the pipeline are mainly sodium aluminate solution crystals and aluminum hydroxide deposits.
Highpressure water jet has extremely high impact energy, which can effectively remove scaling and deposits on the inner wall of pipelines, and its cleaning efficiency is several times that of traditional methods.
As an efficient, environmentally friendly and safe cleaning method, high-pressure water jet cleaning technology has broad application prospects in the field of alumina pipeline cleaning. With the continuous progress of technology, high-pressure water jet cleaning technology will provide more powerful guarantee for the efficient and green production of the alumina industry.
