Intelligent integrated device for microchannel multiple catalytic oxidation

Based on the principle of advanced oxidation treatment technology, free radicals, strong oxidizing particles and oxidizing free radicals (·OH, ·O2, SO4.-, H2O2, O3, OCl-, etc.) are generated in the process of micro-channel catalytic oxidation, which can react with organic pollutants in wastewater in a rapid chain reaction without any choice for oxidative degradation and improve the B/C ratio. The macromolecular organic matter that is difficult to be biodegradable is completely decomposed into simple inorganic molecules such as CO2 and H2O to degrade COD. In the process of treatment, the electron transfer is only carried out between the electrode and the waste water components, and the oxidation reaction relies on the hydroxyl radical generated by the system. It does not need additional oxidation reducing agent, does not produce sludge, and has no secondary pollution. It is a clean treatment method and environmentally friendly technology.

Intelligent integrated equipment for micro-channel catalytic oxidation integrates micro-channel continuous flow application technology and efficient electrocatalytic oxidation technology. Through fine design, it integrates new materials, new processes and new technologies with unique special new equipment, which can achieve high flux, high speed mass transfer between pollutant particles and high time and space conversion with low energy consumption. Strong oxidizing substances such as active hydrogen, active oxygen, and active hydroxyl radicals are produced in situ in the microchannel, and complex components such as structurally stable benzene series, halogenated hydrocarbons, phenols, monocyclic aromatic hydrocarbons, polycyclic aromatic hydrocarbons, heterocyclic hydrocarbons, pyridines and so on in the concentrated membrane solution are treated by catalytic oxidation to achieve ring breaking and chain removal. Complete fine degradation of high concentration, high salt and toxic organic pollutants in a very short time.

High performance titanium base electrode

Titanium as a Yin and Yang electrode base material, anode surface through a number of special precision processes, coating - roasting 16 layers of our company for years of research and development of new nano coating, each layer of different treatment methods, has better electrocatalytic activity than other electrodes, higher acid-base stability, electrolytic oxidation resistance, stable current efficiency, high current density. The distributed electrode group in the microchannel is designed more reasonably, which reduces the resistance on the connector, improves the electrolytic efficiency, reduces energy consumption, and is maintenance-free. In addition, the innovative surface active layer combined with titanium base composite coating structure, greatly improve the service life of the anode is more than five times the national standard quality products.

Innovative electrode coating

The core technology of titanium anode is the advanced nano coating formula. The coating uses manganese, tin and other elements added by ruthenium, iridium, tantalum, rhodium, palladium and other noble metal salt oxides of high entropy alloy particle material, which has a very good bonding force with the substrate to prevent the resolution of titanium electrode. The nano granular coating has strong corrosion resistance, and the nano size enhances the exposure of more electrode surface active area. Under the action of electric field, the surface nano coating can realize the rapid transfer of electrons, which greatly improves the mass transfer efficiency and treatment efficiency of liquid phase, and can catalyze the production of abundant strong oxidizing substances (·OH, SO4.-, OCl-, etc.), which can oxidize contaminated substances everywhere in the micro-channel space, realizing the truly innovative electrode materials.

Unique microchannel reactor

The unique microchannel fine design realizes the dispersion continuous flow of membrane concentrated liquid, the full reaction of the polluted molecular electrode surface with ·OH, the COD removal rate can reach 95%, the mass transfer efficiency is more than 10 to 100 times that of the traditional electrocatalytic oxidation tank, avoiding the attenuation of valuable strong oxidizing free radicals (·OH, ·O2-). The micro-channel design enables the segmented independent distribution of the electrocatalytic plate, which greatly improves the spatial effective catalytic oxidation reaction density and efficiency. The production of strong oxidizing hydroxyl radical per unit area is more than 1000 times that of the common plate. The sewage flow can be controlled from 0 to 60m3/min, and the removal rate can reach more than 90% in a short time. Microchannel reactor fundamentally solves the traditional electrocatalytic process of high energy consumption, high cost and other problems, improve the efficiency of wastewater treatment, energy consumption is reduced by more than 50%, has a good economy, safety, stability and other advantages. In addition, automatic control is conducive to data traceability and quality control requirements.
