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. Compliant with usage standards

Abstract

The invention provides a rotary electrochemical continuous hard removal device, which includes: a treatment tank, an electrochemical hard removal assembly and a cleaning assembly. The electrochemical dehardening assembly includes a cathode plate and an anode plate, the anode plate is arranged inside the treatment tank, and is located below the liquid level of the circulating cooling water, the cathode plate is rotatably arranged above the treatment tank, and the cathode plate Insert the bottom of the circulating cooling water below the liquid level. The cleaning assembly includes: a cleaning knife set, a collection slide and a collection tank, and the cleaning knife set is arranged above the cathode plate. One end of the collection slideway is connected with the cleaning knife group, and the other end is connected with the collection tank, and the fallen scale can be introduced into the collection tank through the collection slideway. The invention creates a rotary electrochemical continuous hard removal device, which can clean the cathode plate during the working process, thereby improving the working efficiency of the electrochemical hard removal treatment and reducing time and labor costs.

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...
