Wherein, 1, Hydrogen Separation film; 1a, Hydrogen Separation film internal surface; 1b, Hydrogen Separation film outer surface; 2, shrouding; 3, base plate; 4, hydrogen discharge pipe; 5, shell; 6, mixed-gas channel; 7, gas outlet duct after filter; 8, insert; 8a, insert outer wall; 8b, insert pipe connecting; 9, gas outlet pipe after filter; 10, mixed gas inlet pipe.
Embodiment
With the drawings and specific embodiments, the utility model is described in further detail below.
A kind of hydrogen purification device shown in Fig. 1, described hydrogen purification device comprises tubulose Hydrogen Separation film 1, shell 5, insert 8, mixed gas inlet pipe 10, gas outlet pipe 9 after filter, hydrogen discharge pipe 4, mixed gas inlet pipe 10 and the rear gas outlet pipe 9 of filter are installed bottom described shell 5, it is inner that described mixed gas inlet pipe 10 directly extends to shell 5, described shell 5 top is provided with hydrogen discharge pipe 4, described shell 5 inside is provided with Hydrogen Separation film 1, described Hydrogen Separation film 1 upper end and shrouding 2, lower end base plate 3 is tightly connected, described Hydrogen Separation film 1 inside is provided with insert 8, described insert 8 outside is surrounded by insert outer wall 8a, insert top is opened wide, insert is connected with mixed gas inlet pipe 10 by insert pipe connecting 8b, described insert 8 inside forms a cavity, between described insert outer wall 8a and Hydrogen Separation film 1, spacing is set to 8mm-18mm, described Hydrogen Separation film 1 adopts copper palldium alloy to be made, gas outlet duct 7 after filtering is provided with between described base plate 3 and mixed gas inlet pipe 10, after described filter, gas outlet duct 7 is through with the rear gas outlet pipe 9 of filter.
Preferably, described Hydrogen Separation film 1 thickness is 3 μm.
Preferably, described insert 8, shell 5, base plate 3 and shrouding 2 all adopt Inconel(nickel alloys) to make.
Hydrogen Separation film 1 has the performance of selectivity through hydrogen molecule.This Hydrogen Separation film can selective permeability be because the hydrogen molecule of the internal surface 1a of Hydrogen Separation film arrives at 2000 DEG C
Hydrogen atom has been dispersed at the temperature of 6000 DEG C, hydrogen atom is subject to the motivating force produced at Hydrogen Separation film outer surface 1b due to Hydrogen Separation film 1 surfaces externally and internally pressure difference when moving to Hydrogen Separation film outer surface 1b, hydrogen atom and other hydrogen atoms are tied at the outside surface 1b of Hydrogen Separation film 1 outside surface being incorporated in Hydrogen Separation film and generated hydrogen.
In shell 5, Hydrogen Separation film 1 is dense film, and makes pending mixed gas isolate hydrogen by described film.
During use, mixed gas is entered by mixed gas inlet pipe 10, mixed gas is channel flow between insert 8 and Hydrogen Separation film 1, because hydrogen at high temperature forms hydrogen atom, and between Hydrogen Separation film surfaces externally and internally, have pressure difference to impel hydrogen to enter in the cavity between shell and Hydrogen Separation film by Hydrogen Separation film, due to the selectivity of Hydrogen Separation film, gas outlet duct after causing other gas to enter into filter through through hole along passage, discharged by gas outlet pipe after filter, the hydrogen after filtering then is discharged by hydrogen discharge pipe again.
