Nano catalytic electrolysis flocculation device

Abstract

The invention discloses a nano catalytic electrolysis flocculation device, relating to an electrolysis flocculation device. The nano catalytic electrolysis flocculation device has the advantages of extremely low working voltage between two adjacent electrodes, large current density, small energy consumption, high electrical efficiency and no electrode consumption and electrolysis, and integrates solid-liquid separation function and gas-liquid separation function. The bottom of a shell is provided with a water inlet; the shell is internally provided with a scum baffle and a watertight shutter; the scum baffle and one inner side of the shell form a water discharging chamber; a gap is reserved between the bottom of the scum baffle and the bottom of the shell; the scum baffle and the other inner side of the shell form a slag discharging chamber; a gap is reserved between the top of the watertight shutter and the top of the shell; a hydrogen exhaust port is arranged on the top of the shell; an electrolyzer is arranged between the scum baffle and the watertight shutter; the top of the electrolyzer is open and the gap is reserved between the top of the electrolyzer and the top of the shell; electrodes are installed in the electrolyzer; a gas-liquid separation chamber is formed in the shell on the upper part of the electrolyzer; and a drain outlet is arranged at the bottom of the shell and us positioned between the watertight shutter and the adjacent electrolyzer.

Description

technical field [0001] The invention relates to an electrolytic flocculation device, in particular to a nano-catalytic electrolytic flocculation device with a titanium electrode covered with a nano-catalytic material as an anode. Background technique [0002] At present, chemical methods and biochemical methods are mostly used for sterilization and purification of water and wastewater, and a large amount of chemical agents need to be added and a large amount of sludge is generated during the treatment process. For example, in the production of tap water, chlorine or sodium hypochlorite is mostly used to disinfect the water body, followed by flocculation, sedimentation and filtration. In wastewater treatment, flocculants are usually added for flocculation reaction, followed by sedimentation or air flotation separation, and then biochemical treatment. Although this treatment method can play a certain role, there are disadvantages such as high operating cost, large amount of s...

Problems solved by technology

However, some problems have been exposed during the operation of the existing electrolysis device. One is that after a period of operation of the fixed packing micro-electrolysis treatment device, the packing is easy to agglomerate and channeling occurs, which greatly reduces the treatment effect; Although the fluidized bed solves the problem of agglomeration, in order to ensure a fluidized state, the filler needs to be continuously circulated, the power consumption is large, and the filler is easy to lose

The existing electrolysis device also exposed some problems during the operation process. First, the electrode consumption is large, and the electrode material pollutes the water body; The third is that after electrolysis, the solid-liquid separation effect is not ideal, and a second solid-liquid separation is required, and the process is long
