Description

Technical field [0001] The invention belongs to the technical field of membrane air separation nitrogen production equipment, and particularly relates to a testing device for optimizing the comprehensive use effect of air separation membrane modules. Background technique [0002] The principle of membrane air separation is mainly to use the difference in the permeability of nitrogen and oxygen in the air to the same membrane to achieve the separation of nitrogen and oxygen and other gases to produce nitrogen or oxygen. The smallest unit of the membrane has a certain output. Membrane module with nitrogen capacity, see attached figure 1 As shown, all hollow fiber air separation membrane modules are similar in shape and structure, but the dimensions and nitrogen production capacity of membrane modules produced by different manufacturers are not the same, and the same manufacturer has different models. According to the requirements of nitrogen production capacity, each nitrogen gener...

AI Technical Summary

Problems solved by technology

According to the requirements of nitrogen production capacity, each set of nitrogen generator needs to select several air separation membrane modules, generally the membrane modules are used in parallel, that is, the membrane groups are placed horizontally or vertically in parallel on one surface, or in parallel One row is connected in parallel with the other in parallel. This is mainly because it is easy to realize the uniform temperature distribution of the membrane modules during operation, which can simplify the oxygen-enriched collection and pipeline layout of each membrane module, and facilitate the maintenance and replacement of the membrane modules. , so the parallel connection of membrane modules is often used in the prior art, and the cost increase brought about by this simple structure simplification is not considered

This simple parallel connection does not consider the influence of the position of the total air inlet, the position of the nitrogen collection port, the position sequence of different membrane modules, and the spacing of the membrane modules on the comprehensive use effect of parallel connection.

In the existing technology, only after the processing and manufacturing is completed, the on-site system debugging can meet the task. Generally, it is qualified if the margin is increased by about 20%. The process is very rough and it is easy to cause a lot of waste of resources.

In the prior art, there is no equipment for optimizing and testing the parallel comprehensive use effect of nitrogen generator membrane modules, so as to save costs and resources
