【摘要】：氧氣是維持人類生命活動不可缺少的條件，然而在某些特殊情況下人們不得不面對缺少氧氣的環(huán)境，或者需要高濃度氧氣的情況，這時就需要考慮通過一定的工藝方法來制備和儲存氧氣。現(xiàn)有的制氧設(shè)備往往和壓氧設(shè)備分體設(shè)計，便攜性和可操作性較小。本文的主要目的就是要設(shè)計一種既可以以日常生活中的空氣為原料制備高濃度氧氣，又可以將高濃度氧氣加壓并灌裝入氧氣儲存裝置的小型智能一體設(shè)備。 氧氣的制備可以通過多種方法來實現(xiàn)，本文在介紹和比較了多種氧氣制備方法的基礎(chǔ)上對變壓吸附制氧工藝進行了深入的探討，詳述了變壓吸附原理，常用吸附劑的性能比較，吸附過程的數(shù)學(xué)模型等，并以此工藝為基礎(chǔ)進行了小型變壓吸附制氧系統(tǒng)和壓氧系統(tǒng)的設(shè)計。主要工作包括氣源系統(tǒng)的設(shè)計、空氣壓縮系統(tǒng)的設(shè)計、吸附分離系統(tǒng)的設(shè)計。此后對壓縮機的設(shè)計選型進行了介紹，參考多種國家標(biāo)準(zhǔn)對本課題所用壓縮機進行了選型。由于本課題設(shè)計過程中對體積和重量有較高要求，在完成整機零部件的設(shè)計選型后，對整機進行了結(jié)構(gòu)設(shè)計和優(yōu)化，在實際操作過程中進行了多套方案的比較分析，，并最終采用了本文所述的結(jié)構(gòu)方案。 在一體機結(jié)構(gòu)設(shè)計之后本文對一體機的控制系統(tǒng)進行了研究設(shè)計。本文以C8051f單片機為核心進行了控制系統(tǒng)相關(guān)電路的軟硬件設(shè)計，包括電源電路、信號采集電路、接口輸出電路、人機交互電路等。并對相關(guān)軟件系統(tǒng)，進行程序編寫。 最后，對樣機進行了性能和可靠性測試，測試結(jié)果表明本課題研制的樣機各項性能指標(biāo)均達到了設(shè)計要求，且通過了機器可靠性測試。
[Abstract]:Oxygen is an indispensable condition for the maintenance of human life. However, in some special cases, people have to face the condition of lack of oxygen or the need for high concentration of oxygen. At this time, it is necessary to consider the preparation and storage of oxygen through a certain process. The existing oxygen making equipment is often designed in a separate body with the oxygen pressure equipment. The main purpose of this article is to design a small and intelligent equipment which can make high concentration of oxygen from the air in daily life, and can also pressurize the high concentration oxygen and fill in the oxygen storage device.
The preparation of oxygen can be achieved by a variety of methods. In this paper, based on the introduction and comparison of various oxygen preparation methods, the PSA process is deeply discussed. The principle of pressure swing adsorption, the performance comparison of the adsorbents and the mathematical model of the adsorption process are described in detail, and a small pressure variable pressure is carried out on the basis of this process. The design of the adsorption oxygen making system and the oxygen pressure system. The main work includes the design of the gas source system, the design of the air compression system and the design of the adsorption separation system. After that, the design and selection of the compressor are introduced, and the compressor is selected with reference to a variety of national standards. The weight has a high requirement. After completing the design and selection of the whole machine parts, the structural design and optimization of the whole machine are carried out. The comparison and analysis of multiple sets of schemes are carried out in the actual operation process, and the structural scheme described in this paper is finally adopted.
After the design of one machine structure, this paper studies and designs the control system of the integrated machine. In this paper, the hardware and software design of the related circuit of the control system is carried out with C8051f single chip computer as the core, including the power circuit, the signal acquisition circuit, the interface output circuit, the human-computer interaction circuit and so on. And the program is written for the related software system.
Finally, the performance and reliability of the prototype are tested. The test results show that all the performance indexes of the prototype have reached the design requirements, and the reliability test of the machine has been passed.
