Description

Technical Field

[0001] The utility model belongs to the technical field of environmental protection equipment, in particular to an industrial waste liquid concentration treatment device. Background Art

[0002] The industrial waste liquid concentration treatment device mainly works based on the principle of evaporation concentration. By heating the waste liquid, the water in it evaporates, and the harmful substances are left in the concentrated liquid. During the evaporation process, the water in the waste liquid is evaporated, and the concentration of harmful substances gradually increases, and finally a concentrated liquid is formed. After such treatment, the harmful substances in the waste liquid are effectively separated and removed, which provides convenience for subsequent treatment and utilization.

[0003] Industrial waste liquid concentration treatment devices are widely used in chemical, pharmaceutical, metallurgical, environmental protection and other fields. In the chemical industry, the device can be used to treat waste liquid containing high-concentration salts, organic matter and other substances to achieve waste liquid reduction and resource utilization. In the pharmaceutical industry, it can be used to extract and purify drug ingredients to improve product quality. In the metallurgical industry, it can be used to treat waste liquid containing heavy metal ions to achieve heavy metal recovery and utilization. At the same time, the device also plays an important role in the field of environmental protection, helping to reduce the pollution of industrial waste liquid to the environment.
