Introducing our state-of-the-art Intelligent Integrated Equipment for Micro-Channel Catalytic Oxidation. This advanced system combines micro-channel continuous flow technology with efficient electrocatalytic oxidation for unparalleled performance. Our innovative design seamlessly integrates cutting-edge materials, processes, and technologies into a single, compact unit. The result? Exceptional high-flux, high-speed mass transfer between pollutant particles and rapid time-space conversion with remarkably low energy consumption. Within the microchannels, powerful oxidizing agents such as active hydrogen, oxygen, and hydroxyl radicals are generated, enabling the effective breakdown of complex pollutants. This includes resilient benzene series, halogenated hydrocarbons, phenols, monocyclic and polycyclic aromatic hydrocarbons, heterocyclic hydrocarbons, and pyridines found in concentrated membrane solutions. Through catalytic oxidation, these components undergo complete structural disruption, breaking rings and removing chains. Our equipment ensures the thorough, rapid degradation of high-concentration, high-salt, and toxic organic pollutants, achieving outstanding purification in minimal time.
High Performance Titanium-Based Electrode
Titanium is utilized as the foundational material for both anode and cathode electrodes. The anode's surface undergoes multiple precision processes to meticulously coat and bake 16 layers of revolutionary nano-coatings, a breakthrough developed by our company over many years. Each layer's process varies, endowing the electrode with superior electrocatalytic activity, exceptional acid-base stability, and resistance to electrolytic oxidation. This results in consistent current efficiency and high current density. The microchannel's distributed electrode group design is optimized, reducing connector resistance, enhancing electrolysis efficiency, cutting energy consumption, and ensuring maintenance-free operation. Furthermore, the innovative composite coating, which merges the active surface layer with the titanium base layer, significantly extends the anode's lifespan-exceeding the national standard for high-quality products by more than fivefold.
Innovative Electrode Coating
The titanium-based anode's core technology revolves around an advanced nano-coating formula. This coating employs high-entropy alloy nanoparticle materials from noble metal salt oxides such as ruthenium, iridium, tantalum, rhodium, and palladium, enriched with elements like manganese and tin. The coating exhibits excellent adhesion, safeguarding the titanium electrode from degradation. The nano-scale refined grain coating offers robust corrosion resistance and exposes more active electrode surface areas. Under an electric field, this surface nano-coating facilitates rapid electron transfer, significantly boosting liquid phase mass transfer and processing efficiency. It swiftly catalyzes the production of abundant strong oxidizing substances (·OH, SO4.-, OCl-, etc.), enabling oxidation reactions with pollutants throughout the microchannel space, embodying a truly pioneering electrode material.
Unique Microchannel Reactor
Our unique microchannel refined design ensures the continuous dispersed flow of membrane concentrate and thorough reaction of polluted molecular electrode surfaces with ·OH. This design achieves a COD removal rate exceeding 95% and a mass transfer efficiency 10 to 100 times higher than traditional electrocatalytic oxidation tanks. It prevents the attenuation of valuable strong oxidizing free radicals (·OH, ·O2-). The microchannel configuration allows independent segment distribution of electrocatalytic plates, significantly enhancing the density and efficiency of spatially effective catalytic oxidation reactions. The area of generated strong oxidizing hydroxyl radicals is over 1,000 times larger than that of standard plates. Sewage flow rates can be managed from 0 to 60m³/min, achieving removal rates above 90% in a short period. This microchannel reactor fundamentally addresses the issues of high energy consumption and costs associated with traditional electrocatalytic processes, improving sewage treatment efficiency, reducing energy consumption by more than 50%, and offering numerous benefits, including superior economy, safety, and stability. Additionally, automated control supports data traceability and meets quality control requirements.
