Rotary electrochemical continuous hardness removal device

Abstract

The invention provides a rotary electrochemical continuous hardness removal device. The rotary electrochemical continuous hardness removal device comprises a treatment tank, an electrochemical hardness removal assembly and a cleaning assembly. The electrochemical hardness removal assembly comprises a cathode plate and an anode plate, the anode plate is arranged in the treatment tank and located below the liquid level of the circulating cooling water, the cathode plate is rotatably arranged above the treatment tank, and the bottom of the cathode plate is inserted below the liquid level of the circulating cooling water. The cleaning assembly comprises a cleaning cutter set, a collecting slide way and a collecting groove, and the cleaning cutter set is arranged above the cathode plate. One end of the collecting slide way is connected with the cleaning cutter set, the other end of the collecting slide way is connected with the collecting groove, and falling scale can be guided into the collecting groove through the collecting slide way. According to the rotary electrochemical continuous hardness removal device, the cathode plate can be cleaned in the working process, so that the working efficiency of electrochemical hardness removal treatment is improved, and the time and labor cost is reduced.

Description

technical field [0001] The invention belongs to the field of water treatment equipment, and in particular relates to a rotary electrochemical continuous hard removal device. Background technique [0002] In existing chemical industry systems, cooling water is an integral part of reducing system temperature. However, when the cooling water circulates for a long time, scales often appear on the inner wall of the device. In order to avoid corrosion damage to the device due to scaling on the inner wall, those skilled in the art will remove the hardness before the cooling water enters the device. deal with. [0003] Since the traditional chemical dehardening method will pollute the water quality, the electrochemical dehardening method is generally used in the prior art to treat the circulating cooling water. During the dehardening work, the area near the anode of the processing device is acidic, and the area near the cathode is alkaline, and substances such as calcium ions, mag...

Problems solved by technology

[0004] However, the existing electrochemical dehardening device does not have self-cleaning ability. When a large amount of scale is formed in the cathode area, the staff needs to stop cleaning the dehardening device, which will waste a lot of time and labor costs

In addition, if the cleaning work is not timely, the voltage in the water treatment tank will increase significantly, which will not only cause a waste of energy, but also reduce the processing capacity of the equipment, resulting in insufficient cooling water entering the subsequent system.
