Self-adaptive long-acting rotating conical electric flocculation device

Abstract

The invention discloses a self-adaptive long-acting rotating conical electric flocculation device. The self-adaptive long-acting rotating conical electric flocculation device comprises a conical cathode (1) and a conical sacrificial anode (2), wherein the cathode (1) is disposed in a conical cavity of the sacrificial anode (2), a conical angle of the sacrificial anode (2) with the thickness of 50mm to 300mm is opened downwards and communicated with an outlet of a waste water inlet pipe (3), a speed-adjustable water pump (4) arranged on the waste water inlet pipe (3) pumps waste water into a conical annular reaction pool (5) formed by a gap between the cathode (1) and the sacrificial anode (2), the waste water entering the conical annular reaction pool (5) is treated by applying a constant-current electric field between the cathode (1) and the sacrificial anode (2) so as to form flocculation, and the cathode (1) can be automatically lowered during the consumption process of the sacrificial anode (2) so as to adjust the distance between the cathode (1) and the sacrificial anode (2). The electric flocculation device is high in efficiency, high in usability and easy to maintain; and the sacrificial anode is replaced once a year and even replacement-free lifelong.

Description

technical field [0001] The invention relates to the technical field of electrocoagulation, in particular to a long-acting self-adaptive rotating conical electrocoagulation electrocoagulation electrocoagulation device which has high treatment efficiency for waste water, is easy to maintain and can reduce the replacement frequency of sacrificial anodes to once a year or even lifelong. Flocculation device. Background technique [0002] At present, the electrocoagulation method is one of the main methods of wastewater treatment. Usually, a voltage is applied to multiple pairs of parallel electrode plates to allow conductive wastewater to meander through them to generate current. The aluminum or iron electrode located at the anode becomes ions due to electrochemical action, and flocculates after combining with hydroxide in water. The flocculation adsorbs various pollutants in the water. Due to its low density and the auxiliary effect of the hydrogen generated by the cathode, it ...

AI Technical Summary

Problems solved by technology

However, there are certain problems in the current design of the flocculation tank. The waste water flows meanderingly in the reaction tank, and the efficiency is different in different places. The flocculation will be silted up in some places with a slow flow rate, which leads to: 1. High failure, 2. The system efficiency is not high

At the same time, because the anode is a sacrificial electrode, it will gradually wear out over time, but the design of multiple sets of parallel electrodes makes it difficult to replace
