Hydrogen purification device

The raw hydrogen gas containing saturated water is separated by a first stage condenser, a first stage separator, a second stage condenser, and a second stage separator to separate the saturated water. After relative treatment (requiring a cold source or chilled circulating water), it enters the first stage deaerator. Under the action of palladium catalyst and at a temperature greater than 100 ℃, the hydrogen gas is pre treated to effectively remove impurities such as oxygen and carbon monoxide from the hydrogen gas. After cooling, filtering, and steam water separation, it enters an adsorption dryer filled with high-efficiency carbon dioxide and trace water specific adsorbents for deep treatment. The two-stage parallel connection avoids the priority water absorption function of molecular sieves and synchronously processes trace amounts of carbon dioxide, hydrocarbons, and trace water in the hydrogen gas. The dried hydrogen gas is filtered through high-precision nickel tubes to remove dust and sent to the process point for use. The sentence is:..

This device runs according to a self written program, and a selection control button is added to the operation panel to autonomously select the regeneration cycle, eliminating resource waste. All data is collected on the control touch screen, and sound and light warnings can be issued for abnormal pressure and temperature, prompting inspection. The PLC outputs 485 protocol and can be remotely controlled through connection.

Adopting a split design, the mechanical part of the open pipeline and the electrical control part of the explosion-proof cabinet are installed. A sealed junction box is added to the power supply part of the on-site equipment, and the hard pipe is connected to the electrical control box. The regenerated blowing gas is connected to the flame arrester and then externally connected to a relatively high outdoor location for discharge.

Install a pneumatic valve at the inlet of the cooling water to automatically open the regeneration process, with a regeneration water consumption of less than 0.1m3/h

The outline drawing of the equipment should be sketched first and confirmed by the purchaser before production can be scheduled to ensure similarity in appearance. Details should not be marked to avoid conflicts in pipe routing.
