Abstract
The invention provides a double-sealing flexible type no-central-tube helium membrane component. The double-sealing flexible type no-central-tube helium membrane component is characterized in that the two ends of a hollow fiber-membrane filament (1) are provided with epoxy sealing heads (2) which are provided with concave grooves (3); and the concave grooves (3) are internally provided with O-shaped rubber rings. The hollow fiber-membrane filament (1) is made of polyimide, polycarbonate or polysulfone, and is specially used for separating helium. The double-sealing flexible type no-central-tube helium membrane component provided by the invention has the advantages that the double-sealing flexible type no-central-tube helium membrane component is adopted to extract helium in helium-containing water-soluble gas, the gas flows in the hollow fiber filament, and the helium permeates to the outside of the filament by utilizing the pressure difference between the inside and the outside of the hollow fiber filament, so that the Reynolds number of the gas can be effectively increased and the gas is close to the ideal full-mixing piston flow state; the concentration of the helium in the helium-containing water-soluble gas can be reduced to 0.02%, or even lower, and the recovery rate of the helium can reach more than 95%.
Description
Technical field
The present invention relates to extract field containing helium Water Soluble Gas, be specially the soft formula non-stop layer pipe helium membrane module of a kind of double envelope.
Background technology
Along with developing rapidly of modern science and technology, helium application is the most wide, China's helium industry that is found to be containing helium Water Soluble Gas indicates a new direction, but containing concentrations of helium in helium Water Soluble Gas (in relatively natural gas, helium content is high) on the low side, it is desirable to have the membrane separator of high efficiency, high separability energy carries out separation and Extraction to helium.
Summary of the invention
Technical problem solved by the invention is to provide a kind of double envelope soft formula non-stop layer pipe helium membrane module, thus solves the problem in above-mentioned background technology.
Technical problem solved by the invention realizes by the following technical solutions: hollow-fibre membrane tow (1) two ends are provided with epoxy sealing head (2)；Epoxy sealing head (2) is provided with concave groove (3)；Concave groove is provided with O-shaped rubber ring in (3).Hollow fiber film thread (1) material is polyimides, Merlon or poly-maple.Hollow fiber film thread (1) is that helium separation is special.
The technique effect of the present invention: typically carry out gas helium content containing helium Water Soluble Gas relatively low, it is about 0.1～10%, the response rate that helium carries out extracting helium by conventional film isolation technics can be relatively low, the soft formula non-stop layer pipe helium membrane module of double envelope is taked to extract containing the helium in helium Water Soluble Gas, gas is by flowing in hollow fibre filament, utilize the pressure differential inside and outside hollow fibre filament, make helium permeability to outside silk, can effectively increase the Reynolds number of gas, plug flow regime is entirely mixed close to ideal, can be even lower by being down to 0.02% containing the concentrations of helium in helium Water Soluble Gas, helium recovery rate is up to more than 95%.
Accompanying drawing explanation
Fig. 1 is the schematic flow sheet of the present invention.
In figure: 1, hollow-fibre membrane tow；2, epoxy sealing head；3, concave groove；4, O-shaped rubber ring.
Detailed description of the invention
As it is shown in figure 1, hollow-fibre membrane tow 1 two ends are provided with epoxy sealing head 2；Epoxy sealing head 2 is provided with concave groove 3；O-shaped rubber ring 4 it is provided with in concave groove 3.Hollow fiber film thread 1 material is polyimides, Merlon or poly-maple.Hollow fiber film thread 1 separates special for helium.
Gas helium content is typically carried out relatively low containing helium Water Soluble Gas, it is about 0.1～10%, the response rate that helium carries out extracting helium by conventional film isolation technics can be relatively low, the soft formula non-stop layer pipe helium membrane module of double envelope is taked to extract containing the helium in helium Water Soluble Gas, gas is by flowing in hollow fibre filament, utilize the pressure differential inside and outside hollow fibre filament, make helium permeability to outside silk, can effectively increase the Reynolds number of gas, plug flow regime is entirely mixed close to ideal, can be 0.02% even lower by being down to containing the concentrations of helium in helium Water Soluble Gas, helium recovery rate is up to more than 95%.
