Novel electrolysis device

Abstract

The invention discloses a novel electrolysis device. The novel electrolysis device mainly comprises a tank body, a rotating device, a rotating powered device, an electrolysis power source and a polarity changing power source, wherein one cathode roller is arranged at each of the two ends in the tank body; a cathode plate strip sleeves the two cathode rollers; anode plates are parallelly placed on the side surfaces of the cathode plate strip; anode conductive bars connected with the anode plates are connected with the anode of the electrolysis power source; the two ends of one of the two cathode rollers are separately connected with the rotating device and the rotating powered device; the rotating powered device is connected with the cathode of the electrolysis power source, is connected with the anode of the polarity changing power source, and is provided with a change-over switch used for switching a current loop; and polarity changing semicircular arc plates connected with the cathode of the polarity changing power source are arranged on the outer edges of the cathode rollers. The novel electrolysis device has the advantages that automatic cleaning is achieved, the cathodes do not scale, electrolytic efficiency is high, pickling facilities are not required, damage of pickling to the polar plates is eliminated, the anodes are not subjected to polarity changing, and service life of the anode plates is prolonged.

Description

technical field [0001] The invention relates to water treatment equipment, in particular to electrolytic chlorine production disinfection equipment. Background technique [0002] On-site sodium hypochlorite generators are widely used to produce sodium hypochlorite because of their safety, stability and reliability. The device has a high degree of automation and realizes unattended operation. The current problem is that the cathode plate will deposit dirt during the electrolysis process, and it is necessary to periodically interrupt the electrolysis and switch to the descaling program. The current descaling methods include: pickling and dissolution method and reverse current method. After the cathode scaling is removed , and then turn to normal electrolysis, the disadvantages of these two methods are: [0003] The pickling method will corrode the electrode and affect the life of the electrode.

Problems solved by technology

The current problem is that the cathode plate will deposit dirt during the electrolysis process, and it is necessary to periodically interrupt the electrolysis and switch to the descaling program. The current descaling methods include: pickling and dissolution method and reverse current method. After the cathode scaling is removed , and then turn to normal electrolysis, the disadvantages of these two methods are:

[0003] The pickling method will corrode the electrode and affect the life of the electrode. The pickling is not easy to complete, and the residual scale will also affect the electrolysis efficiency.

[0004] The reverse current method will cause the anode to undergo a reduction reaction, and the anodic oxide coating will partially generate metal products after receiving electrons. At the same time, the hydrogen evolution reaction will cause hydrogen permeation, which will cause the anode coating to fall off, seriously affecting the life of the anode, and has not been widely used.
