Description
Technical field
The present invention relates to a kind of hydrogen gas segregators with expansion joint, specifically tubular ceramic base hydrogen gas separation material is worn
Be placed in the cavity with expansion joint, in two end of tubular ceramic base hydrogen gas separation material successively wear respectively metal clips, compression ring,
Graphite gasket；Two taper seals are connected the encapsulation of tubular ceramic base hydrogen gas separation material in the cavity by threads,
Form hydrogen gas segregator, which there is tubulose hydrogen gas separation material to be easily changed, and structure is simple, easy to operate, save at
This advantages that, especially suitable for middle and small scale Hydrogen Separation and purifying.
Background technique
With the rapid development of the industries such as electronic information, semiconductor and LED manufacture, promote to ultra-pure hydrogen (purity>
99.9999%) demand increasingly increase (Chen Zili etc., the source of hydrogen and purification in production of polysilicon, low temperature and special gas,
30 (2012) 21-23), while requirements at the higher level are proposed to Hydrogen Separation and purification technique.The purification technique of hydrogen mainly has:
Pressure-variable adsorption (PSA), temp.-changing adsorption (TSA), cryogenic separation and UF membrane.With pressure-variable adsorption, temp.-changing adsorption and cryogenic separation phase
Than, UF membrane because have the characteristics that small investment, equipment are simple, low energy consumption, it is easily operated, free from environmental pollution due to be widely used,
The technology is particularly suitable for middle and small scale Hydrogen Separation and purifying.The membrane material that can be used for Hydrogen Separation and purifying has polymer
Film, molecular screen membrane, carbon film, zirconium dioxide film, titanium dioxide film and Metal Palladium and its alloy film etc., wherein Metal Palladium and its alloy
Film is concerned in Hydrogen Separation and purification application due to the high and resistant to high temperature characteristic of, selectivity good with hydrogen permeability.
Currently, the technology almost all for the production ultra-pure hydrogen having been commercialized is Metal Palladium and its alloy film purification technique, by
It is limited in by mechanical strength etc., palladium film thickness is generally at 100 μm or so, and not only permeated hydrogen amount is small, but also manufacturing cost is high.In order to gram
This disadvantage is taken, it has been proposed that Metal Palladium film to be carried on to technology path (S.Uemiya, the A on porous supporting body surface
Palladium/Porous-Glass Composite Membrane for Hydrogen Separation. Chemistry
Letters, 17 (1988) 1687-1690), this palladium-based composite membrane can keep very high mechanical strength, and can be by palladium film thickness
It is down to 5-10 μm, therefore permeated hydrogen amount is greatly improved, and significantly reduces the manufacturing cost of palladium film.As supporter
Material has porous metals, porous ceramics and cellular glass etc., and porous ceramics with its excellent chemical stability, thermal stability with
And extensive Commercial sources and it is most widely used.
For pure palladium/ceramic composite membrane, when being lower than 300 DEG C and H2Hydrogen Brittleness Phenomena can occur for contact, destroy palladium film, therefore
When carrying out Hydrogen Separation using palladium film, operating temperature generally requires to be higher than 300 DEG C, this will necessarily be related to palladium/Ceramic Composite
The elevated-temperature seal problem of film.More common connection type is mechanical connection (Gu Yu usually between ceramics pipe fitting and metal pipe line
Dawn etc., the connection of ceramics and metal, Chemical Industry Press, 2010), i.e., it is realized by connector, screw thread, flange, cutting ferrule etc.
The sealing of ceramic pipe fitting and connection with other components, have the advantages that simple and easy, at low cost, convenient disassembly.However, ceramic
The thermal expansion coefficient of material is low, and the thermal expansion coefficient at 25-700 DEG C is about 7~8 × 10-6K-1(electric and electronic insulation technology
Handbook, China Machine Press, 2008, P482)；Thermal expansion coefficient of the stainless steel at 25-700 DEG C is 18.6 × 10-6K-1
(metal material handbook, Chemical Industry Press, 2009), the two thermal expansion coefficient differs greatly, straight using mechanical connection manner
When connecing ceramic material and stainless steel sealing, it is unmatched that thermal expansion will be led to the problem of in high temperature or heating and cooling process.
In order to slow down ceramics pipe fitting and thermal dilation difference caused by metal sealing in applied at elevated temperature, there has been proposed various
Method, such as：(Huang Yan, Hu little Juan, a kind of pipe junction cutting sleeve suitable for hot conditions of Chen Weidong, the Chinese patents such as Huang
CN101440901A, 01,2006) by the way of cutting ferrule sealing, ceramic material both ends are sealed respectively, it later will wherein one end
It is connect with sealer, other end free extension, this mode can eliminate the difference of thermal expansion, but structure is not compact enough and needs
It is tightly connected three times, increases the chance of gas leakage；(Xu Hengyong, Li Chunlin, Tang Chunhua, a kind of multi-channel metal palladiums such as Xu
Or palladium alloy composite membrane hydrogen gas segregator, Chinese patent CN101642684A, 02.2010；Xu Hengyong, Tang Chunhua, collection preheating and
It exchanges heat in the multi-channel metal palladium-based composite membrane hydrogen separation device of one, Chinese utility model patent, CN203379783U,
01.2014) it is connected to one end of palladium membrane component using metal winding pipe etc., is then sealed in palladium membrane component by the way of welding
In separator cavity, flexible by metal winding pipe etc. has effectively buffered palladium/ceramic compound film tube and metal sealing is in heat
The stress generated when expansion, the cyclone separator arrangement ensure that the airtightness of interface, but also cause separator manufacture it is relatively cumbersome,
The problem of palladium/ceramic composite membrane is not easy to replace and separator cavity is unable to Reusability.(Huang Yan is looked into and is come by the emperor himself Huangs etc., recklessly small
A kind of elevated-temperature seal device of ceramic pipe fitting of beautiful, Chinese invention patent, CN102979981A, 03.2013) use thermal expansion coefficient
The controlled expansion alloy material manufacture sealer cavity being close with ceramic material, is sealed company to ceramic pipe fitting in conjunction with cutting ferrule method
It connects, efficiently solves the problems, such as the thermal expansion stress generated between seal cavity more than ceramics in high temperature or frequent heating and cooling environment,
But because the cost of controlled expansion alloy material is very high, this necessarily causes the manufacturing cost of the sealer to increase.And by expansion of metal
Section is combined with separator cavity, will be the feasible method for solving thermal expansion stress release.
