Modular normal-pressure electrochemical treatment device

Abstract

The invention discloses a modular normal-pressure electrochemical treatment device. The modular normal-pressure electrochemical treatment device comprises an open type scale precipitation water tank,wherein the inner part of the open type scale precipitation water tank is containing space; a cover plate is arranged in an opening position of the open type scale precipitation water tank; the open type scale precipitation water tank is provided with a water inlet end and a water outlet end; the containing space is internally provided with a front section, a middle section and a rear section; anelectrode plate assembly is arranged in the middle section; the electrode plate assembly is provided with a plurality of positive electrode plates; the bottom parts of the positive electrode plates are connected to the bottom part of the open type scale precipitation water tank, and the top parts are connected to a positive electrode connecting part; a negative electrode plate is arranged betweentwo adjacent positive electrode plates; a water distribution system is formed by the negative electrode plates and the positive electrode plates which are in alternative arrangement. The modular normal-pressure electrochemical treatment device disclosed by the invention has the beneficial effects that (1) by combining different numbers of modular middle sections, the numbers of the negative electrode plates and the positive electrode plates are increased, the treatment ability of equipment is increased, and a treatment effect is ensured; (2) positive electrode chlorine can be guided into an alkaline water pond by utilizing an axial fan, a vortex gas corrosion problem of a traditional closed tank body can be avoided, and meanwhile, chloride ions in circulating water can also be removed; onthe premise that stable running of a circulating water system is ensured, the concentration multiple of the circulating water is increased, the water consumption is reduced, and energy conservation and emission reduction are realized.

Description

technical field [0001] The invention relates to the fields of scale inhibition, scale removal and chlorine removal of circulating water, in particular to a modular atmospheric pressure electrochemical treatment device. Background technique [0002] The safe and stable operation of the circulating cooling water system and the improvement of heat exchange efficiency are of great significance to the safe and stable production of enterprises. At present, the treatment scheme of industrial circulating water is basically the antiscaling and sterilization method of chemical agents, but this treatment method cannot completely treat the sewage, but instead produces new sewage discharge, pollutes the environment, and wastes a lot of water resources. This processing method has poor controllability and high operating cost. Under the constraints of current environmental protection policies and pollution discharge standards, the development of the chemical agent law is limited. [0003]...

AI Technical Summary

Problems solved by technology

At present, most electrochemical treatment devices are closed pressure-bearing metal boxes with built-in cathode and anode plates. Due to the limitation of the box structure, the area of ​​the cathode and anode plates is limited, and the processing capacity of the equipment is limited.

At the same time, this kind of closed box is easy to cause vortex in the upper part of the box, resulting in corrosion of equipment and pipelines
