Hydrogen continuous transmission device

Abstract

The invention relates to gas supercharging purification equipment, in particular to a continuous hydrogen feeding device which is applicable to 35MPa hydrogen supercharging purification. The equipment solves the problems that gas emitted by a traditional mechanical hydrogen compressor with oil contains oil and affects the normal operation of a fuel cell and that abrasion occurs in the moving parts in a mechanical hydrogen compressor without oil. The equipment consists of a first level supercharging system, a second level supercharging system and a thermal exchange device. The pressure of hydrogen of general purity (purity is lower than 99 percent) is 1 to 2MPa and increases to 35MPa after passing through the first level supercharging system and the second supercharging system, and the purity of the hydrogen of general purity is higher than 99.999 percent. In the process of hydrogen supercharging and liquid circulation, a control and data collecting system collects and processes the data of temperature, pressure and flow rate, and controls the switching state of various valves in the system. The equipment has the advantages of high automation, all-around measurement parameters, high energy efficiency, convenient operation, high efficiency, safe operation, convenient maintenance, low investment and low noise, etc.
