SEA SAND DECHLORINATION APPARATUS AND SEA SAND DECHLORINATION METHOD

摘要

Disclosed is a sea sand dechlorination apparatus, comprising: a box (1) provided with a first electrolytic tank (11), a sedimentation tank (12) and a second electrolytic tank (13); a conveying device (2) comprising an obliquely arranged conveying belt (21), with one end of the conveying belt (21) being located in the first electrolytic tank (11), and the other end thereof extending out of the box (1); a first electrolysis device (3) arranged at the end of the conveying belt (21) that is located in the first electrolytic tank (11), the first electrolysis device (3) comprising a first anode screen plate (31), a first diaphragm (32) and a first cathode plate (33), which are correspondingly arranged from top to bottom, with the conveying belt (21) being arranged between the first anode screen plate (31) and the first cathode plate (33); and a second electrolysis device (4) detachably arranged in the second electrolytic tank (13), wherein the first electrolytic tank (11) is connected to the sedimentation tank (12) by means of a first pump body (110); an overflow dam (121) is arranged between the sedimentation tank (12) and the second electrolytic tank (13); and the second electrolytic tank (13) is in communication with the first electrolytic tank (11). The apparatus can continuously produce sand and has a high sand yield.
