Zinc is an important metal element in the chemical industry, widely used in alloy manufacturing, galvanizing and fertilizer fields. However, wastewater discharge of zinc has an environmental impact. Therefore, the development of efficient zinc removal technology is particularly important. The combined extraction centrifugal extractor provides an ideal solution for zinc extraction.

Chemical properties and environmental effects of zinc

Zinc is usually found in water bodies in the form of zinc ions (Zn² +). Its excessive discharge may cause toxicity to aquatic life and affect water quality. Therefore, proper treatment of zinc-containing wastewater is an important link to ensure the ecological environment.

Working principle of combined extraction centrifugal extractor

The combined extraction centrifugal extractor realizes the effective separation of zinc ions in wastewater through the centrifugal force generated by high-speed rotation. The specific steps include:

1. Feed operation: the wastewater containing zinc is injected into the equipment.

2. Centrifugal separation: high-speed rotation causes zinc ions to settle due to density differences.

3. Precipitation collection: The settling zinc precipitation is collected through the discharge system, which is convenient for subsequent treatment.

Optimized extraction conditions

In order to improve the extraction efficiency of zinc, the following conditions should be optimized:

1. Centrifugal speed: between 5000-7000 rpm, can effectively improve the sedimentation rate of zinc.

2. Treatment time: The recommended treatment time is 20-30 minutes to fully separate zinc.

3. pH adjustment: In a neutral environment, the separation effect of zinc is better.

Follow-up treatment and resource recovery of zinc

The extracted zinc precipitates can be recovered by roasting and chemical treatment, realizing the reuse of zinc, which can not only reduce the environmental burden, but also support the development of related industries.

The application of combined extraction centrifugal extractor to extract zinc element in chemical industry provides efficient technical support for water pollution control and has a good market prospect.
