Problems solved by technology

Its structure is to arrange multiple plates in parallel in the tank, and control the direction of water flow through water distribution pipes and water collection pipes. The flow channel design is one-dimensional contact, that is to say, the water and the plates are in the same direction from surface to surface. Contact, uneven and insufficient contact, which in turn affects the adequacy of the aforementioned reactions

Embodiment Construction

[0051] see figure 1 , figure 2 . 1 is the pole plate, and 2 is the water flow direction. In the two design methods, the water flow and the pole plate are in one-dimensional contact.

[0052] see Figure 3 to Figure 4 . This embodiment includes a tank body 11 with an upper cover plate 12 to seal the entire tank body, and the length, width and height are 500mm, 200mm, and 150mm respectively; the two sides of the tank body are respectively provided with a water inlet 13 and a water outlet 14, Several pole plates 15 are arranged in parallel in the tank body, and a water outlet 18 is arranged on the pole plate. The water outlet can be a through hole on the pole plate, or a gap at the edge of the pole plate; The device is made up of a rotating shaft 16, a driving wheel 17 and a blade 19. The blade 19 has a length of 120 mm, is fixed on the rotating shaft, and is arranged between every two adjacent pole plates. The driving wheel 17 drives the rotating shaft 16 to rotate at a spe...

Abstract

The invention relates to a high-efficiency electrochemical reactor which comprises a sealed groove, wherein a plurality of pole plates are arranged in the groove in parallel, and stirring blades are arranged among the pole plates and are rotated through a rotating shaft. In the invention, one-dimensional contact between the water flow and each pole plate is changed into three-dimensional contact,thereby achieving reasonable structure and sufficient reaction.

Description

technical field [0001] The invention belongs to the field of environmental protection sewage treatment, and more specifically relates to an electrochemical reactor used in an electrochemical treatment method. Background technique [0002] The main reactions of electrochemistry in water treatment are oxidation, reduction, indirect oxidation, indirect reduction, electrocoagulation, electroflotation, and electro-Fenton effect. Among them, COD removal is mainly electrocoagulation, oxidation and Fenton effect. A good The reactor design must take into account the adequacy of the three effect reactions, and the adequacy of these reactions is very much related to the water flow mode of the reactor. [0003] The existing electrochemical reactor structure mainly has two kinds of series and parallel, see figure 1 , figure 2 . Its structure is to arrange multiple plates in parallel in the tank, and control the direction of water flow through water distribution pipes and water collec...
