A vertical electro-flocculation reactor

Abstract

The invention relates to a vertical electric flocculation reactor which comprises a reaction chamber housing, an upper end cover, a first electrode bar, a second electrode bar, a first electrode plate and a second electrode plate, wherein the upper end cover is fixed at the top of the reaction chamber housing; the first electrode bar and the second electrode bar are fixed on the upper end cover and extend into the reaction chamber housing; the first electrode plate and the second electrode plate are assembled on the first electrode bar and the second electrode bar respectively and arrayed alternately; a first opening and a second opening are formed in the first electrode plate and the second electrode plate respectively; the first electrode bar and the second electrode bar penetrate through the second opening and the first opening respectively in a noncontact manner; the edge of the first electrode plate is close to an internal wall of the reaction chamber housing; a distance between the edge of the second electrode plate and the internal wall of the reaction chamber housing is greater than that between the edge of the first electrode plate and the internal wall of the reaction chamber housing; and a water inlet connector and a water outlet connector are arranged at the bottom and the top of the reaction chamber housing respectively. The reactor can generate an eddying effect, prolong reaction time, occupies small land, and is convenient to transport and good in treatment effect.

Description

technical field [0001] The invention relates to the field of oilfield sewage treatment equipment, in particular to a vertical electrocoagulation reactor. Background technique [0002] Flocculation is one of the most important physical and chemical treatment methods in water treatment technology, and electrocoagulation technology is a new type of flocculation technology. Electrocoagulation technology uses cations produced by soluble anodes (such as iron anodes, aluminum anodes, and other metal anodes) to undergo hydrolysis, polymerization, and oxidation reactions in water under the action of an applied voltage to generate a series of flocculants, such as polynuclear hydroxyl complexes. The colloids in the water lose their stability under the action of the flocculant, and collide with each other to form larger flocs, so as to achieve separation. At the same time, the tiny bubbles that generate oxygen and hydrogen on the anode and cathode have good adhesion properties and have...

AI Technical Summary

Problems solved by technology

[0009] At present, the existing electroflocculation reactors are difficult to adapt to the requirements of field operations in oil fields, and generally have the following deficiencies:

[0010] 1. Large area and poor mobility; 2. Difficult to replace electrodes; 3. The time of sewage in the reactor is short and the flocculation time is insufficient
