Problems solved by technology
There are two types of oxygen-enriched membrane modules: roll type and flat type. The existing flat-type oxygen-enriched membrane modules are fixed by glue, such as image 3 As shown, the oxygen-enriched membrane 1' is attached to the membrane plate 2' through the double-sided adhesive tape 3', and the installation gap 5' between the oxygen-enriched membrane 1' and the membrane plate 2' is sealed by the transparent tape 4'. The disadvantages are: first, because the oxidation of the glue

The invention relates to a flat oxygen-enriched membrane component, which consists of an upper template, a middle template and a lower template which are fastened. One end of the upper template, one end of the middle template and one end of the lower template are provided with oxygen outlets A, B and C which are communicated; the insides of the upper template and the lower template are provided with oxygen-enriched membranes A and D respectively; two sides of the middle template are provided with oxygen-enriched membranes B and C respectively; air passages A and B are arranged between the adjacent oxygen-enriched membranes; one end of the air passage A and one end of the air passage B are communicated with the atmosphere, and the other end of the air passage A and the other end of the air passage B are communicated with the oxygen outlets A, B and C; the oxygen outlets B and C are provided with oxygen passage covers B and C of through holes; and the flat oxygen-enriched membrane component is characterized in that heat fused welding layers are arranged between the oxygen-enriched membranes A, B, C and D and the corresponding upper template, the middle template and the lower template respectively. The oxygen-enriched membranes are physically welded and fixed by adopting heat fusion, the defects of adhesion and fixation of adhesive are thoroughly changed, the service life is ensured, and the utilization ratio is improved.
Description
technical field [0001] The invention relates to an oxygen-enriched membrane module for preparing oxygen, in particular to a flat-plate oxygen-enriched membrane module, which belongs to the membrane separation technology. Background technique [0002] Oxygen-enriched air has a combustion-supporting effect, high heat utilization rate, and obvious energy-saving effect, so it is widely used in industries, medical care and other fields. The oxygen-enriched membrane uses the different permeation rates of various components in the air when they pass through the membrane. Driven by the pressure difference, the oxygen in the air passes through the membrane preferentially to obtain oxygen-enriched air. There are two types of oxygen-enriched membrane modules: roll type and flat type. The existing flat-type oxygen-enriched membrane modules are fixed by glue, such as image 3 As shown, the oxygen-enriched membrane 1' is attached to the membrane plate 2' through the double-sided adhesive ...
