Features | Detail |
Ultra-pure gas | Ultra-pure (99.999%) gas generation with continuous purity monitoring function can extend the life of the equipment and save a lotof maintenance and replacement costs. |
Reliable reliability | The system is equipped with an overvoltage protection device. If the hydrogen output flow exceeds the maximum pressure, the generator will automatically shut down. |
Stable gas flow | Continuous and stable gas output: The generator can be used continuously or intermittently, and the gas produced is stable and high in purity |
exhaustive test | Each unit has passed a comprehensive factory test, in line with national standards and beyond the industry standards |
On demand supply | The delivery pressure is adjustable from 0 to 0.35 MPa The higher flow conveying range can meet your specific hydrogen requirements |
Automatic Water-feeding | The float and the pump work together to achieve automatic water-feeding |
NO | Overview of Zhongxinda hydrogen production process |
1 | The modular electrolyzer with bipolar pressurization technology adopts special design and materials, so the electrolyzer will not leak during operation, has long service life and does not need any maintenance |
2 | In the compact electrolyzer, non asbestos patent material is used as diaphragm, the pure nickel mesh is used as cathode and anode,patent material is used as sealing gasket, carbon steel and pure nickel coating are used as bipolar plate. The precise design of sealing structure is environmentally friendly. |
3 | The Special activation treatment is carried out on the cathode of the electrolyzer to ensure the high water electrolysis efficiency with low power consumption and save electric energy for customers; |
4 | An electrolyzer is composed of a plurality of stage plates;The voltage of each electrolyzer is adjustable from 1.8 to 2.2, and the DC voltage is adjustable from 30V to 58V according to the rated voltage of electrolytic ;(subject to hydrogen production data of electrolyzer) maximum DC current 820a (detailed parameters confirmed with hydrogen production during engineering design) |
5 | The 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. |
6 | Through special technology, the hydrogen generator can be designed and operated under the pressure of 1.50 MPa (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. |
7 | All process valves on the main production lines (H2 gas line, O2 gas line and Alkali liquor circulation pipeline) will be imported from Swagelok,USA / Taiwan Hyundai. the quality of electrolytic water is the highest in the world. |
8 | All process pressure vessels are made of 316L SS stainless steel to ensure that they are suitable for water electrolysis(KOH solution as electrolyte has high working pressure (1.50 MPa (g) and 90 ℃ working temperature ) |
9 | The process pipeline material is 316L SS stainless steel, which is used for H2 gas pipeline, O2 gas pipeline and alkali 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. |
10 | The pneumatic diaphragm valve imported from the United States is used to regulate the working pressure, the pressure difference between H2 alkali level and O2 alkali level and the working temperature. |
11 | All on-line analyzers （Including percentage of H2 in O2 analyzer, percentage of O2 in H2 analyzer）are sensed from imported equipment to monitor gas purity and send alarm / interlock system signals when any poor purity is found in the gas. |
12 | It is used for PLC control configuration and easy to operate man-machine interface for operators to operate and monitor hydrogen generator, including data acquisition and display, historical data recording and trenching, alarm and interlocking, operation priority classification, etc., fully ensuring the safety and reliability of hydrogen generator. |
13 | All equipment is handed over to the customer in Skidded-type. In order to shorten the installation and erection works on the project site, the customer interconnects the Skidded equipment. |
