Use of hydrogen generators
Hydrogen generator is composed of electrolytic tank, pure water tank, hydrogen/water separator, collector, dryer, sensor, pressure regulating valve, switching power supply and other components. Hydrogen can be produced by electrolysis only of pure water. After electrification, the cathode of the electrolytic cell produces hydrogen, the anode produces oxygen, and the hydrogen enters the hydrogen generator. Oxygen is discharged into the atmosphere. A hydrogen generator separates hydrogen from water. After the hydrogen enters the dryer for dehumidification, it is adjusted to the rated pressure (adjustable from 0.02 to 0.45mpa) by the pressure regulator and regulating valve and then exported. The hydrogen production pressure of the electrolytic cell is controlled by the sensor at about 0.45mpa. When the pressure reaches the set value, the power supply of the electrolytic cell is cut off. When the pressure drops below the set value, the power supply will resume.
Usage of hydrogen generator:
Hydrogen generator powered on, first with the raw material of hydrogen displacement system, from the three empty, stay in the system of high purity nitrogen replacement after clean, according to user's raw materials needed for high purity hydrogen and hydrogen content in hydrogen content, reference to a data table, to the selected operating temperature, operating pressure and chi put gas, then electric heating tube, palladium from valve 2 high purity hydrogen. The temperature control method can be set according to the manual. From the high purity hydrogen obtained by palladium diffusion to the actual high purity hydrogen obtained, it still needs a period of time in the pipeline before the replacement valve 2, usually about 2-3 hours. Since the hydrogen generator has to pass the product quality inspection before leaving the factory, the pipelines of valve 1 and valve 3 are filled with high pure nitrogen, and the pipelines from valve 2 to the front of the pipeline are filled with high pure nitrogen. When the hydrogen generator is not in use, the power should be cut off first. After the device is cooled, all valves are closed and then the gas is stopped, so as to reduce the time for replacing the system in the next use. When we use synthetic ammonia feedstock gas and electrolytic hydrogen as hydrogen source for hydrogen generator, the measured operating temperature, operating pressure and droop discharge volume are used. For some data of purified hydrogen volume of hydrogen generator, users can refer to the data in this table to choose the appropriate operating conditions. It is generally believed that in the case of a certain palladium tube thickness, the greater the pressure difference between the inlet and outlet, the higher the temperature, the greater the amount of hydrogen penetration, but the average pressure of 8 -- 3 kg/cm 2, the operating temperature of 300 -- 400℃ is appropriate.
