The four-in-one AWE hydrogen production equipment consists of electrical power installations, electrolyzer, hydrogen production process installations, purification process installations and auxiliary installations.

 

Power installations consist of transformer-rectifiers and stacks. For the transformer unit, a 24-pulse oil-immersed water-cooled transformer-rectifier is used to convert 10kV grid power into the input voltage of the rectifier that converts the power into direct current (DC) for the electrolyzer (voltage: 0~734V, current: 0~6520A).

 

The electrolyzer and hydrogen production process installations consist of the electrolytic unit, hydrogen separator unit, oxygen separator unit, alkali pump unit, gas-liquid separator unit, liquid collector unit, manual valves, pneumatic valves, local instruments and remote instruments. The electrolytic unit is to decompose water into hydrogen and oxygen. The hydrogen separator unit and the oxygen separator unit are to initially collect the hydrogen and oxygen produced by the electrolytic unit. The alkali pump unit adopts variable-frequency drive to quickly recirculate the hydrogen and oxygen produced in the electrolytic unit to the hydrogen/oxygen separator units through alkali circulation that controls the temperature of the entire hydrogen production system at the same time. The gas-liquid separator unit separates the liquid from the hydrogen/oxygen and discharges it to the liquid collector unit. The liquid collector unit will drain water regularly. The valves are to control the flow of gas and liquid as required. The instruments are collect various parameters of gas and liquid, such as temperature, purity, flow rate, etc., as the basis for control and decision-making.

 

The purification process installations consist of deoxidizer, dryer, gas-liquid separator, liquid collector, manual valves, pneumatic valves, local instruments and remote instruments. The deoxidizer is to remove the oxygen from the hydrogen through chemical reactions, thereby improving the purity of the hydrogen, and preheating the hydrogen. The dryer is to further dry and purify the hydrogen. The hydrogen separator and the oxygen separator are to initially collect the hydrogen and oxygen produced by the electrolytic unit. The gas-liquid separator unit separates the liquid from the hydrogen/oxygen and discharges it to the liquid collector unit. The liquid collector unit will drain water regularly. The valves are to control the flow of gas and liquid as required. The instruments are collect various parameters of gas and liquid, such as temperature, purity, flow rate, etc., as the basis for control and decision-making.

 

The auxiliary installations consist of the cooling water unit, frozen water unit, compressor, pure water unit, raw material water tank and alkali preparation unit. The cooling water unit is to cool down the alkali liquid and alkali pump to ensure the safe and stable operation of the electrolyzer and alkali pump. The frozen water unit is to cool down the hydrogen/oxygen from the hydrogen/oxygen separator and deoxidizer, where the water vapor is transformed to droplets that are discharged through the gas-liquid separator to improve the purity of hydrogen and oxygen. The compressor unit is to provide air source for the pneumatic valves and other instruments in the hydrogen production process and purification process. The pure water unit is to filter potassium ions and other mineral elements in tap water to ensure the electrochemical quality of electrolytic unit and other units to protect the device from corrosion. The raw material water tank unit is to store the pure water produced by the pure water unit to ensure sufficient pure water before the equipment is powered on. The alkali preparation unit is to mix the alkali solution fully and to provide alkali solution for the hydrogen production unit.
