Title:
次亜塩素酸塩を生成する方法及び耐スケール設備を有する関連する海水電解槽
Document Type and Number:
Japanese Patent JP5828058
Kind Code:
B2
Abstract:
A significant decrement of the rate of accumulation of scale on electrode and other inner surfaces of a sea water electrolyzer of an electro-chlorination plant, is achieved by intermittently ejecting pressurized sea water through arrays of nozzles that produce energetic (high speed) jets adapted to encroach deep inside the interelectrodic gap spaces of an elongated pack of planar parallel interleaved electrodes. The kinetic energy of the jets is gradually absorbed by the process liquid flowing through the gap spaces from the inlet end to the outlet end of the tubular casing of the electrolyzer containing the elongated electrode pack. The input of kinetic energy in a transverse or inclined direction of encroachment of the jets in the liquid flowing in the gap spaces disrupt the laminar flow causing an energetic turbulence in the interelectrodic body of liquid which effectively hinder a stable accumulation of scale, a good portion of which is swept by the liquid stream out of the electrolyzer into drains in the lower part of electrolyzer.
