Nickel is an important metal that is widely used in fields such as stainless steel and battery manufacturing. However, the wastewater discharge of nickel has a serious impact on the environment, so it is particularly important to develop efficient nickel removal technology. The high efficiency and energy saving combined extraction centrifugal extractor provides a new idea for nickel extraction.

Environmental characteristics of nickel

Nickel is present in water mainly in the form of nickel ions (Ni² +). Its excessive existence will cause toxicity to aquatic organisms and affect ecological balance. Excessive emissions of nickel can also lead to human health risks, so controlling nickel emissions is essential for environmental protection.

Separation mechanism of combined extraction centrifugal extractor

The high-efficiency and energy-saving combined extraction centrifugal extractor separates nickel ions from wastewater by centrifugal force. The working steps include:

1. Waste water input: The waste water containing nickel is injected into the equipment.

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

3. Precipitation collection: Collect settled nickel regularly for subsequent treatment.

Optimized extraction conditions

Key factors to optimize nickel extraction efficiency include:

1. Centrifugal speed: Increasing the speed can enhance the settling speed of nickel, and the recommended range is 3000-6000 rpm.

2. Processing time: Appropriate extension of processing time can improve the extraction rate of nickel, usually 15-25 minutes.

3. pH adjustment: The precipitation effect of nickel is better under acidic conditions (pH 4-6).

Subsequent resource recovery of nickel

The nickel precipitates after extraction can be recovered by roasting and chemical treatment, and the reuse of nickel can not only reduce the production cost, but also reduce environmental pollution.

The application of high efficiency and energy saving combined extraction centrifugal extractor to extract nickel from wastewater provides a new technical support for water pollution treatment and has a good market prospect.
