Ultra-pure hydrogen purifier

The raw hydrogen containing saturated water passes through the primary condenser, the primary separator, the secondary condenser and the secondary separator to separate the saturated water, and then enters the primary deaerator after relative treatment (cold source or chilled circulating water is required). Under the action of palladium catalyst and at a temperature greater than 100 ℃, the hydrogen is pretreated to effectively separate the oxygen, carbon monoxide and other impurities in the hydrogen, and then the steam and water are separated after cooling and filtering, Then enter the adsorption dryer filled with high-efficiency carbon dioxide and micro-water special adsorbent for advanced treatment. The two-stage parallel connection avoids the priority water absorption function of molecular sieve, and simultaneously processes the micro-carbon dioxide, hydrocarbons and micro-water in the hydrogen. The dried hydrogen is separated and sent to the process point for use after being filtered by high-precision nickel tube..

The device operates according to the self-compiled program. The operation panel is equipped with a selection control button, which can automatically select the regeneration cycle and eliminate the waste of resources. All data are collected on the control touch screen. The abnormal pressure and temperature can send an audible and visual alarm, prompt the patrol inspection, PLC output 485 protocol, and can be connected for remote control.

The split design is adopted. The mechanical part of the open pipeline and the electrical control part of the explosion-proof cabinet are installed. The power supply part of the field equipment is equipped with a sealed junction box, and the hard pipe is connected to the electrical control box. The regeneration purge gas is connected to the flame arrester and then connected to the outdoor relatively high place for discharge.

The cooling water inlet end is equipped with a pneumatic valve, and the regeneration starts automatically, and the regeneration water consumption is less than 0.1m3/h

The outline drawing of the equipment shall be sketched first, and the production can be scheduled only after it is confirmed by the demander, so as to ensure that the outline is similar, and the details are not marked, so as to avoid pipeline conflict.
