Electrode for low-voltage electrode boiler

The electrode for the low-voltage electrode boiler comprises an electrode body arranged in the boiler, the electrode body is an electrode set formed by splicing a plurality of electrodes, the section of the electrode set is in a regular polygon shape, the electrode comprises an electrode rod, an electrode arm A and an electrode arm B, and the electrode arm A and the electrode arm B are arranged in the circumferential direction of the electrode rod. The electrode arms A and the electrode arms B are each provided with a plurality of electrode fans at intervals in the length direction, in every two adjacent electrode rods, the electrode fans on the electrode arms A are inserted into electrode fan gaps on the electrode arms B at intervals, and electrode fan sets are formed between the electrode fans and the electrode fans on the electrode arms B. Through mutual combination of the electrode rods, the electrode fan groups are formed. And the electrode fans on the electrode arm A and the electrode arm B are inserted
