Green recycling processing method for pretreatment of waste lithium-ion batteries and device thereof

The invention discloses a green recycling processing method for pretreatment of waste lithium-ion batteries and a device thereof. The processing method comprises the steps that S1, the waste lithium-ion batteries are put into a NaCl solution and soaked for full electric discharge, then cleaned with clean water and air dried; S2, before the crushing, the adsorbent bearing board is clamped in a flexible clamping groove on the inner side of a cone-shape box, the obtained waste lithium-ion batteries from step S1 are placed in a crushing machine for an impact crushing using a dry method, meanwhile an air pump is opened, the power of the air pump is controlled, so that the polluting gases and the absorbent produced in the crushing process are fully contacted and absorbed by the adsorbent; S3, the unabsorbed polluted gases in S2 are discharged into the adsorption liquid through an air guide pipe. The device comprises a cone-shape body (1), an absorbent bearing plate (2), an air pump (3), an air guide pipe (4), a gas
