一 . tekniska fördelar medtitan avkalande anodplattor
1. Breakthrough innovation in material properties Titanium anode plates are based on titanium metal, and the dense passivation film (TiO₂) formed on its surface can remain stable in extreme environments of pH 2-12. Compared with traditional graphite or lead anodes, titanium substrates show excellent corrosion resistance in high-salinity media containing chloride ions (such as seawater and industrial circulating water). For example, in a cooling tower system with a chloride ion concentration of 3000 ppm in a petrochemical enterprise, the service life of titanium anode plates is more than 5 years, while ordinary metal anodes can only last for 3 months. Further, mixed precious metal oxides (MMO, such as RuO₂-IrO₂-TiO₂) are coated by the sol-gel method to form a gradient coating structure: the surface layer is enriched with RuO₂ to improve the catalytic activity, and the inner layer TiO₂ enhances the matrix bonding force. Experiments show that the oxygen evolution potential of the coating is 0.2 V lower than that of the platinum electrode, and the chlorine evolution efficiency is increased by more than 30%, which directly minskar energikonsumtionströskeln för den elektrokemiska reaktionen.
2. The dimension of electrochemical efficiency has leaped up. The MMO coating of the titanium anode plate has achieved dual optimization through the solid solution network structure: Enhanced catalytic activity: The introduction of RuO₂ reduces the oxygen evolution overpotential from 1.6 V to 1.3 V, and the working Spänningen reduceras med 30% vid samma strömtäthet . Att ta ett cirkulerande vattensystem med en behandlingskapacitet på 100 m³/h Som exempel kan den årliga kraftbesparingen för titananodplattan nå 21, 000 kWh. Mångfald av reaktionsprodukter: Reaktiva syrearter (ROS) såsom hydroxylradikaler (· OH) och ozon (O₃) som genereras under elektrolysprocessen kan inte bara oxidera och sönderdelas organisk skala såsom biologisk slem, utan också förstöra den gitterstrukturen för caco₃ (främja omvandlingen av kalcitfas till aragonitfas) och inse den fysiska STR -skalaen.
3. Collaborative innovation of structural design and intelligent control Three-dimensional mesh structure: The porous titanium matrix is ​​prepared by laser engraving technology, the specific surface area is increased by 5 times, the current distribution uniformity is improved by 40%, and the descaling efficiency is increased by 40% in the seawater desalination project. Intelligent control system: integrated pH/ORP sensor and Fuzzy PID-algoritm, realtidsjustering av spänning och pulsfrekvens . Ett stålväxtfodral visar att systemet kan minska energiförbrukningen med 22% och förhindra anodpassivering genom polaritetsomkopplingsfunktion .}
4. Double benefits of environmental protection and economy Zero chemical agent addition: completely avoid equipment corrosion and secondary pollution of scale inhibitors caused by traditional pickling. Cost advantage of the whole life cycle: Although the initial investment of titanium anode plate is relatively high (about 2,000 yuan/㎡), its service life of more than 12 years (graphite anode is only 2-3 år) och återanvändbar titanmatris minskar den totala kostnaden med mer än 60%.

2. Tekniska flaskhalsar och utmaningar med titananodplatta
1. High cost restricts large-scale application Precious metal coatings (Ru, Ir, etc.) account for more than 70% of the cost of titanium anode plates. Taking RuO₂-IrO₂ coating as an example, the price of its raw materials is as high as 800-1200 yuan/gram, resulting in a cost of more than 2,000 yuan per square meter of anode plate. Although some studies have tried to use Mn-Co-Fe oxides to replace precious metals (reducing costs by 60%), its catalytic activity is still 15%-20% lower than that of MMO coatings.
2. Adaptability to complex water quality environments is limited to high hardness water bodies (>800 mg/L): Ca(OH)₂ flocs generated in the cathode area are prone to block the flow channel, and additional mechanical filtration devices are required. Organic pollutant-rich environment: Grease and colloidal substances will cover the active sites of the MMO coating, and regular acid washing and maintenance are required (the frequency is 50% higher than that of traditional processes).
3. Technical barriers to manufacturing processes Coating uniformity control: The sol-gel method for preparing MMO coatings requires precise control of sintering temperature (±5℃) and oxygen partial pressure, otherwise cracking or peeling is likely to occur. Large-scale production problems: Existing equipment is difficult to stably coat titanium substrates with a length of more than 3 meters, which restricts its application in storskaliga industriella vattenbehandlingssystem .
3. Framtida tekniska genombrott
1. Utveckling av icke-ädla metallkatalytiska systemforskning och utvecklar Mn-co-Fe-o multi-oxidbeläggningar och förbättra konduktiviteten genom att dopar sällsynta jordelement (som LA, CE), för att uppnå katalytisk aktivitet på 90% av MMO-beläggningar .}
2. Circular economy model construction Establish a titanium substrate-coating separation and recycling production line, aiming to increase the precious metal recovery rate to more than 85%, and at the same time develop titanium substrate surface regeneration technology (such as plasma cleaning) to achieve more than 10 times of reuse of the substrate.
