High-efficiency self-control horizontal rotary-electrode electro-catalysis oxidation dirt removal device

Abstract

The invention discloses a high-efficiency self-control horizontal rotary-electrode electro-catalysis oxidation dirt removal device. The high-efficiency self-control horizontal rotary-electrode electro-catalysis oxidation dirt removal device comprises a cylinder; an end cover is arranged at each of the two ends of the cylinder for sealing; a central rotating shaft is arranged in the centre of the cylinder; an electrode group is arranged on the central rotating shaft in a sleeving manner; the two ends of the central rotating shaft penetrate out of the end covers at the two ends; one end of the central rotating shaft is connected with a shaft seat at the tail end, and the other end of the central rotating shaft is connected with a driving device; the cylinder is placed horizontally; the electrode group comprises a plurality of electrode plates which are arranged in parallel on the central rotating shaft in a sleeving manner at intervals; the electrode plates consist of sacrificial anode plates and cathode plates; the anode plates and the cathode plates are arranged alternately; the sacrificial anode plates and the cathode plates are disc plates with equal diameter; the central rotating shaft is arranged in central holes of the anode plates in a sleeving manner and is fixedly connected with the central holes of the anode plates in a contact manner; a plurality of convex bumps are arranged on the edge of each sacrificial anode plate and around the centre of a circle; a connecting hole is formed in each convex bump; the convex bumps on each sacrificial anode plates correspond to one another; an anode energizing shaft penetrates through each connecting hole; the two ends of each anode energizing shaft are connected with the end covers at the two ends of the cylinder; the central rotating shaft is arranged in the central holes of the sacrificial anode plates in the sleeving manner.

Description

technical field [0001] The invention relates to the field of sewage electrocoagulation treatment, in particular to electrocatalytic decontamination equipment. Background technique [0002] Water can be contaminated by organic and inorganic substances from a variety of sources including domestic, municipal, industrial and agricultural sources. Contaminants can be in solution, colloid or in suspension. Colloids, especially negatively charged colloids, are often the main form of water pollutants. [0003] Electrocoagulation is an electrochemical method of treating water contaminated with various substances, which has a cathode and a sacrificial anode in an electrocoagulation reactor. Supplying current to the electrodes results in the release of metal cations (usually iron or aluminum) from the sacrificial anode and the formation of hydrogen gas at the cathode. Other chemicals that help remove pollutants from water can be formed that participate in a variety of processes. ...

Problems solved by technology

However, despite the development of existing technologies for electrocoagulation, most of the known electrocoagulation-based wastewater treatment cannot be fully commercialized cost-effectively or in large-scale treatment projects.
