1 | An electrolytic consists of 68 cells with maximum DC voltage.136V,Rated DC current 740A,ensure that the H2 flow is 20NCMH and the 02 flow is 10NCMH(detailed parameters shall be confirmed during detailed engineeringdesign) |
2 | l Chemical KOH (concentration 25-30%) is used as an additive in electrolytes to increase the conductivity, but it does not consume chemicals during normal operation,so it does not need to be supplemented in the electrolyte after the first start-up. |
3 | l Through special technology, the hydrogen generator can be designed and operated under the pressure of 1.50MPa(g)without using any gas compressor.Therefore, if the customer needs more pressure and has to use a hydrogen compressor to increase the pressure,the gas output of the generator will be pressurized to 1.50mpa(g).so as to improve the reliability of the generator and save the capital cost for the customer. |
4 | l All process valves on the main production lines (H2 gas line, 02 gas line and Alkali liquor circulation pipeline) willbe imported from Swagelok,USA / Taiwan Hyundai.the quality of electrolytic water is the highest in the world.All process pressure vessels are made of316LSS stainless steel to ensure that they are suitable for water electrolysis. |
5 | l (KOH solution as electrolyte has high working pressure (1.50 MPa(g) and 90 C working temperature )The process pipeline material is 316LSS stainless steel, which is used for H2 gas pipeline, 02 gas pipeline andalkali circulation pipeline.The design of the pipe size is accurate to ensure that the flow rate of the gas passing through the pipe is within the limits of the international standard code. |
6 | l The pneumatic diaphragm valve imported from the United States is used to regulate the working pressure, thepressure difference between H2 alkali level and 02 alkali level and the working temperature. |
7 | l All on-line analyzers (Including percentage of H2 in 02 analyzer, percentage of 02 in H2 analyzer) are sensedfrom imported equipment to monitor gas purity and send alarm / interlock system signals when any poor purityis found in the gas. |
8 | l lt is used for PLC control configuration and easy to operate man-machine interface for operators to operate andmonitor hydrogen generator, including data acquisition and display, historical data recording and trenching alarmand interlocking, operation priority classification, etc., fully ensuring the safety and reliability of hydrogen generator. |
