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-Based Electrode
Titanium is meticulously chosen as the base material for both anode and cathode electrodes. The anode's surface undergoes a series of precision processes to coat and bake an astounding 16 layers of innovative nano-coatings, crafted painstakingly by our company over the years. Each layer's unique processing method endows the electrode with unparalleled electrocatalytic activity, superior acid-base stability, exceptional electrolytic oxidation resistance, stable current efficiency, and high current density. The ingeniously designed distributed electrode group within the microchannel minimizes connector resistance, boosts electrolysis efficiency, cuts down energy consumption, and requires no maintenance. Moreover, the innovative composite coating structure, merging the surface active layer with the titanium base layer, dramatically extends the anode's service life - exceeding national high-quality product standards by over five times.
Innovative Electrode Coating
The cornerstone of our titanium-based anode technology is an advanced nano-coating formula. This coating integrates high-entropy alloy nanoparticles of noble metal salt oxides, including ruthenium, iridium, tantalum, rhodium, and palladium, enhanced with elements like manganese and tin. This combination ensures a robust bond with the substrate, preventing the titanium electrode from degradation. The nano-scale refined grain coating boasts impressive corrosion resistance, while its size maximizes the exposure of electrode surface active areas. Under an electric field, the surface nano-coating facilitates rapid electron transfer, markedly enhancing liquid phase mass transfer efficiency and processing speed. It swiftly catalyzes the generation of potent oxidizing agents (·OH, SO4.-, OCl-), initiating oxidation reactions with pollutants throughout the microchannel space, embodying a groundbreaking electrode material.
Unique Microchannel Reactor
Our unique microchannel design achieves a dispersed, continuous flow of membrane concentrate, ensuring a comprehensive reaction between polluted molecular electrode surfaces and ·OH radicals. The COD removal rate surpasses 95%, with mass transfer efficiency exceeding traditional electrocatalytic oxidation tanks by 10 to 100 times. This design prevents the decay of valuable oxidizing free radicals (·OH, ·O2-); independently segmented electrocatalytic plates vastly enhance the density and efficiency of spatial catalytic oxidation reactions. The generation of strong oxidizing hydroxyl radicals per unit area is over 1,000 times that of conventional plates. Adjustable sewage flow rates from 0 to 60m³/min ensure a removal rate above 90% in a brief period. This microchannel reactor fundamentally addresses the high energy consumption and cost issues of traditional electrocatalytic processes, boosting sewage treatment efficiency, cutting energy consumption by over 50%, and offering excellent economy, safety, and stability. Additionally, automated control ensures data traceability and adherence to quality control standards.
