Scale removal system

Abstract

An object of the present invention is to provide a scale removal system capable of effectively avoiding a disadvantage that a scale is deposited on electrodes and a load, the system includes at least a pair of electrodes which are submerged into for-treatment water to electrochemically treat the for-treatment water, and a scale collection unit (a filter) disposed on a downstream side of the electrodes, the for-treatment water passed through the filter is split into flows, one flow is supplied to the load, then combined with the for-treatment water from the electrodes and returned to an inlet side of the scale collection unit, and the other flow is returned to an inlet side of the electrodes.

1 . A scale removal system configured to remove a scale from for-treatment water which is supplied to a load in a circulating manner, the system comprising: 
 at least a pair of electrodes which are submerged into the for-treatment water to electrochemically treat the for-treatment water; and    scale collection means disposed on a downstream side of the electrodes,    wherein the for-treatment water passed through the scale collection means is split into flows, one flow is supplied to the load, then combined with the for-treatment water from the electrodes and returned to an inlet side of the scale collection means, and the other flow is returned to an inlet side of the electrodes.    
     
     
         2 . The scale removal system according to  claim 1 , which further comprises: 
 a channel through which the for-treatment water bypasses the scale collection means.    
     
     
         3 . The scale removal system according to  claim 1  or  2 , which further comprises: 
 hypochlorous acid resolving means for resolving hypochlorous acid in the for-treatment water.    
     
     
         4 . The scale removal system according to  claim 3 , wherein the electrochemical treatment by the electrodes is performed on predetermined conditions, and the hypochlorous acid resolving means is operated in a state in which the electrochemical treatment is not performed.
