Ultra-high purity hydrogen separator

Abstract

The invention provides an ultra-high purity hydrogen separator. The ultra-high purity hydrogen separator comprises a shell taking the shape of a circular pipe and a coil spirally wound outside the shell, a first plug and a second plug are arranged at the end part of the shell, the first plug is provided with an ultra-high purity hydrogen outlet, the outlet is communicated with an ultra-high purityhydrogen outlet pipe, the second plug is provided with a mixed hydrogen inlet, the inlet is communicated with a mixed hydrogen inlet pipe through the coil, the shell is divided into three cavities bya first baffle plate and a second baffle plate, a working cavity is internally provided with a palladium membrane pipe and a liner pipe, a waste gas outlet is arranged on the outer wall of the shell,and the outlet is communicated with a waste gas outlet pipe and a waste gas collecting cavity. The disclosed ultra-high purity hydrogen separator has the characteristics of simple and compact structure, safety, reliability and long service life, and is suitable for separating various mixed hydrogen systems; the separating efficiency of hydrogen reaches more than 90%, and the purity of the hydrogen reaches more than 99.9999%.

Description

technical field [0001] The invention belongs to the technical field of hydrogen separators, in particular to an ultra-high-purity hydrogen separator. Background technique [0002] Palladium and its alloy membranes have a series of advantages such as very high hydrogen permeation selectivity, good mechanical and thermal stability, and catalytic activity. Palladium and palladium membranes have attracted widespread attention in the application of catalytic membrane reactions and hydrogen separation and purification. The development of palladium membranes has experienced from the initial dense pure palladium and palladium alloy membranes (mainly palladium silver, palladium yttrium alloys) to palladium and palladium-based composite membranes that have attracted much attention and have good application prospects. preparation). In the 1980s, Wileman et al. studied the idea of ​​separating hydrogen isotopes with palladium alloy membranes. Luo Luo et al. of the China Academy of Eng...
