Abstract
Description
Technical Field
[0001] This utility model relates to a liquid level measuring device, belonging to the field of metallurgical technology. Background Technology
[0002] Vacuum evaporation is an evaporation operation performed under vacuum. It offers advantages such as the ability to handle heat-sensitive materials that decompose easily at high temperatures, increased heat transfer driving force, higher evaporation rate per unit heat transfer area of the evaporator, and the ability to utilize low-temperature heat sources, thus reducing energy consumption. Therefore, vacuum evaporation is commonly used in processes such as water recycling, resource recovery, and waste liquid concentration. However, in the vacuum evaporation process, the container is always exposed to environments with high temperature, high flow rate, high corrosion, high negative pressure, and high salinity.
