technical field
[0001] The invention relates to an extraction device, in particular to an extraction device for extracting nickel sulfate from waste batteries of an easy-to-clean type. Background technique
[0002] Nickel-cadmium battery is the most widely used battery series at present, and it is also a kind of battery that focuses on environmental pollution problems. Cadmium is a highly toxic substance and is carcinogenic, while nickel is also carcinogenic and has obvious effects on aquatic organisms. hazards. According to the US EPA survey, the cadmium in discarded cadmium-nickel batteries accounts for 75% of the total cadmium in municipal solid waste. Lead-acid battery is currently the world's largest output and most widely used battery. Sales account for more than 30% of global battery sales. The annual output of lead-acid batteries in my country is nearly 30 million kWh. The pollution of this type of battery is mainly the pollution of heavy metal lead and electroly...
