Product Description 1: Company Introduction: Zhejiang WellCare Technology Co., Ltd, established in September 2008, is a provincial science and technology enterprise and a national high-tech enterprise. Zhejiang WellCare Technology Co., Ltd focuses on hydrogen production technology enterprises with advanced green hydrogen production technology, green hydrogen production equipment and equipment, providing customers with customized hydrogen production solutions for electrolysis of water, research and development, design and manufacturing of hydrogen production equipment and equipment, large-scale new energy hydrogen production engineering services, engineering design and manufacturing of water electrolysis hydrogen production post-treatment equipment, and hydrogen production system operation and maintenance services. Relying on the foundation of China's cluster manufacturing industry, Zhejiang WellCare Technology Co., Ltd. takes becoming the world's leading supplier of green hydrogen equipment and solutions as its corporate mission, and provides global customers with efficient, high-quality, stable and economical electrolyzed water hydrogen production products.2: electrobath 2.0. WE-GH series innovative lightweight Qianfang electrolyzer, to achieve a unit hydrogen production of 1200Nm3/h (average chamber voltage 2V), through the comprehensive optimization of bipolar plates and electrodes, the chamber voltage is reduced by 5-10%, and long-term stable operation under a current density of 4000A/M2, DC power consumption reaches the national first-class energy efficiency standard of 4.3kwh/Nm3 (when the unit hydrogen production is 1000Nm3/h), significantly reducing operating costs by 10-20%. The product has the following features: 2.1 Lightweight: current density 4000A/m2, small chamber number of about 230. The weight of the electrolytic cell is 39.8 tons, which is 20-30% lighter than the conventional Qianfang alkali tank; 2.2 Stable electrode: using non-precious metal highly active electrodes, HER and OER both use classic nickel catalytic thermal spraying holes, which have been verified by more than 20 years of actual operation and are stable and reliable; 2.3. Stable tank temperature: using the third generation bipolar plate, high mastoid, large flow channel, sufficient electrolyte circulation cooling, good consistency of tank temperature of each electrolytic chamber, uniform thermal expansion and contraction; 2.4. Smooth flow channel: The design of the flow channel is further optimized, with good patency, uniform fluid distribution, elimination of the dead zone of the chamber through drainage, and elimination of gas accumulation. 2.5. Long life: the length of the electrolytic cell is short, the weight of the electrolytic chamber is light, the load of the sealing gasket is light, the overhaul cycle of the electrolytic cell is longer, and the stability reaches more than ten years. 2.6. EC on-line electrolyzer safety management module (optional according to customer needs), through online diagnosis and measurement module and dynamic algorithm, automatic collection of data, real-time monitoring of each electrolytic chamber voltage to find abnormalities in time, at the same time, can also trend analysis of the historical data of voltage, issue early warning, to ensure the safe and stable operation of the entire system. 3: Process description 1)Hydrogen production unit Including electrolyzer, gas-liquid processor, water tank, alkali tank, control cabinet, rectifier cabinet, transformer, flame arrester, hydrogen detection device, a complete set of instrumentation device and microcomputer control system. 2)Working principle of hydrogen production by water electrolysis The working principle of the water electrolysis hydrogen production system is a water electrolysis cell composed of a diaphragm immersed in a pair of electrodes in the electrolyte to prevent gas penetration, when a certain direct current is passed, the water will decompose, and then the cathode precipitates hydrogen, and the anode precipitates oxygen. The reaction formula is as follows:3) Overview of the system processTechnical parameter table of water electrolysis hydrogen production equipment1,Device modelSDQ1000/1.62,Hydrogen production1 - 1500m3/h3,Hydrogen purity≥99.999%(After purification frame treatment)4,System operating pressureAvailable in 0.8~1.6MPa Run under any pressure5,Operating temperature <90oC6,DC power consumption4.6KW.h/m3H27,Electrolyzer overhaul cycle≥10 Years8,Control modePLC+Fully automatic unattended control of industrial computerApplications:1: Hydrogen refueling station2: Heating and power supply3: Synthetic green ammonia4: Integrated circuit chip(High purity hydrogen 99.9999999%)
