The invention discloses a hydrogenation system, a hydrogenation machine and a hydrogen filling flow rate control method, the hydrogenation system comprises a hydrogenation pipeline, a control valve group, a flow rate detection module and a controller, and the control valve group and the flow rate detection module are arranged on the hydrogenation pipeline; the control valve group is formed by connecting N quantitative control valves in parallel, the internal medium flow rates of all the quantitative control valves in the control valve group under the same condition are different, and all the quantitative control valves in the control valve group can be combined to obtain a plurality of valve combinations with different internal medium flow rates under the same condition; and the controller is used for controlling the on-off state of each quantitative control valve in the control valve group according to the hydrogen filling flow rate detected by the flow rate detection module and a preset control strategy, so that the hydrogen filling flow rate of the to-be-hydrogenated equipment meets a preset requirement. The equipment cost can be effectively reduced while the hydrogen filling flow rate can be automatically adjusted to meet the hydrogenation flow rate requirements under different working conditions.

    本申请公开了一种加氢系统、加氢机及氢气加注流速控制方法,加氢系统包括加氢管路、控制阀组、流速检测模块和控制器,控制阀组和流速检测模块设置在加氢管路上;控制阀组由N个定量控制阀并联组成,控制阀组中的每个定量控制阀在相同条件下的内部介质流速各不相同,控制阀组中的各个定量控制阀可以组合得到多个在相同条件下的内部介质流速各不相同阀门组合;控制器用于根据流速检测模块检测到的氢气加注流速按照预设的控制策略控制控制阀组中各个定量控制阀的开关状态,以使待加氢设备的氢气加注流速满足预设要求。本申请能够在实现自动调节氢气加注流速以满足不同工况下的加氢流速要求的同时有效降低设备成本。
