Description

[0002] The dehydration process is an important part of the production process of magnesium chloride desiccant, among which the dehydration of magnesium chloride under the protection of hydrogen chloride gas is the top priority in the production process. However, the melting and bonding of materials on the dryer tray during the dehydration process restricts the sustainability and stability of production.

[0003] At present, the materials in the air dryer will melt and stick together on the tray or inside the device after a period of time, which will lead to the inability to continue production. The entire production line needs to be shut down for manual cleaning of the materials, which is inefficient, labor-intensive, and has safety risks in confined space operations. The man-hours required for cleaning the trays each time are high. Due to manual cleaning, the manhole needs to be opened, and a large amount of magnesium chloride finished particles are treated as waste due to deliquescence when exposed to air moisture. During cleaning, a large amount of magnesium chloride dust particles float and scatter, causing great harm to the equipment and human body in the workshop. The frequent shutdown of the entire production line for 5-7 days each time and 8-10 times a year seriously affects the output of the entire magnesium chloride desiccant production device, causing stress corrosion of the main equipment and the start-up and shutdown losses of its ancillary equipment, and reducing the service life.
