Spiral channel column anode

Abstract

The invention relates to the technical field of life and industry water processing technique, in particular to a spiral channel column anode which comprises a water inlet, a bottom board, a baffle board, perforated carbon felts, a graphite bar, a proton membrane, a top board and a water outlet, wherein the proton membrane is surrounded to be of a cylinder shape, two ends of the proton membrane are bonded with the top board and the bottom board together to form an anode chamber; holes are evenly distributed on the carbon felts, every two carbon felts are sintered integrally after staggering a certain angle to form the column anode internally provided with a spiral channel; and the graphite bar is screwed into the sintered carbon felts to ensure that the graphite bar and the carbon felts form better contact so as to be convenient for leading electrons out of the anode chamber. Compared with the prior art, the invention increases the attaching area of microorganism and lowers the batter internal resistance as well as improves the electrogenesis property by adopting a packing electrode, prolongs the remaining time of water power and prevents the blockage caused by excessive growth of the microorganism through arranging the spiral channel, and leads the electrode to be strengthened through an improved connecting way of the graphite bar and the carbon felts and the sintering way among the carbon felts.
