A kind of waste battery recycling system and recycling method

Abstract

The invention discloses a waste battery recycling system and a recycling method. The system and method are as below: the waste dry batteries are subjected to two crushing to obtain components of powdered carbon, paper, film, plastics, carbon rods, iron, zinc and copper; the components are dried and have mercury removed, and sent into a vibration sieve to separate powdered carbon; the remaining components are sent into a vibration sieve in a next device; at the same time a blower and a suction fan are arranged on both sides of the vibration sieve in a line, so that lighter components containing paper, film and plastics are blown into a storage barrel and a space bag, and remaining iron, carbon rods, zinc and copper are sent into a conveyor belt of a magnetic separation device to isolate the iron; the remaining carbon rods, zinc and copper are crushed by a biaxial crusher; the carbon rods are crushed into powdered carbon, which is separated and sent into the space bag; and the remaining zinc and copper are sent into an eddy current separator for separation. The invention can carry out effective and environment-friendly recycling, harmless treatment and recycling on waste batteries, and realizes a self existence and continuously fixed recycling mode of resources.

Description

technical field [0001] The invention relates to the field of comprehensive utilization of resources, in particular to a waste battery recovery system and a recovery method thereof. Background technique [0002] Waste batteries generally refer to waste household dry batteries, including zinc-manganese batteries, alkaline dry batteries and other batteries. my country scraps 500,000 tons of waste zinc-manganese batteries every year, but the recovery rate is less than 2%. If they can all be recycled, 110,000 tons of renewable manganese, 70,000 tons of zinc, and 14,000 tons of copper are renewable resources, which are considerable resources. Waste batteries are harmful to the ecological environment and human health, mainly because the chemical substances in waste batteries are released into the environment, and the chemical substances entering the environment will pollute the groundwater, soil and atmospheric environment, and eventually enter the human body through the food chai...

Problems solved by technology

my country scraps 500,000 tons of waste zinc-manganese batteries every year, but the recovery rate is less than 2%

However, in wet treatment, the solubility of various metals in acid is not high, which affects the treatment effect
