Problems solved by technology

[0002] At present, under many conditions that require the use of hydrogen, the demand for hydrogen is constantly fluctuating, and the energy consumption of hydrogen production in water electrolyzers is relatively large. The disadvantages of the preparation system are: if you choose a hydrogen production equipment with a large gas production capacity, it will increase the input costs such as electricity, and will also cause excess capacity of the equipment; if you choose a equipment with a small gas production capacity, it will not be able to meet the needs of end users
However, in actual production, because the amount of hydrogen used by end customers is constantly changing, frequent adjustment of current will affect the stability of gas production by hydrogen production equipment, and the pressure and flow of hydrogen will also change drastically, which will affect the use of customers.

Abstract

The invention discloses an automatic hydrogen supply integrated control system which comprises a hydrogen producer, a primary purification device, a buffer tank, a secondary purification device, a hydrogen compressor, a bus-bar steel bottle group and a decompression current stabilizer, wherein the hydrogen generated by the hydrogen producer enters the buffer tank through the primary purification device, and is output through the secondary purification device; the redundant hydrogen generated by the hydrogen producer enters the hydrogen compressor through the primary purification device, and the hydrogen compressed by the hydrogen compressor is stored in the bus-bar steel bottle group; and the hydrogen stored in the bus-bar steel bottle group is decompressed by the decompression current stabilizer, and the decompressed hydrogen enters the buffer tank and is output through the secondary purification device. According to the automatic hydrogen supply integrated control system, the automatic switch between two hydrogen supply approaches, namely, the hydrogen producer terminal and the bus-bar steel bottle group, is achieved, and the stability of hydrogen supply pressure and flow is guaranteed while the cost of hydrogen production is reduced.

Description

technical field [0001] The invention relates to the technical field of hydrogen preparation, in particular to an integrated control system for automatic hydrogen supply. Background technique [0002] At present, under many conditions that require the use of hydrogen, the demand for hydrogen is constantly fluctuating, and the energy consumption of hydrogen production in water electrolyzers is relatively large. The disadvantages of the preparation system are: if the hydrogen production equipment with large gas production is selected, the input cost such as electricity will be increased, and the overcapacity of the equipment will also be caused; if the equipment with small gas production is selected, it will not be able to meet the needs of end users. [0003] One solution to the above problem is: the hydrogen production equipment changes the hydrogen production by adjusting the current. However, in actual production, because the amount of hydrogen used by end customers is con...
