氧气作为空气中含量丰富的气体，取之不竭，用之不尽。它无色、无味，透明，维持生命。氧气（O2）在空气中的含量为20.9476%（空气中各种气体的容积组分为：N2：78.084%、O2：20.9476%、氩气：0.9364%、CO2：0.0314%、其它还有H2、CH4、N2O、O3、SO2、NO2等，但含量极少），分子量为32，沸点：-183℃。
臭氧是由氧气经过高压电离形成的，这就决定了足量的臭氧需要足量的氧气，足量的氧气需要足量的空气，而在组成空气的含量中，氧气仅占20.9476%；而工业制氧机产生的氧气量可达到80％以上。由此，制氧机便应运而生！启达制氧机经过不断改进，氧气的纯度最高可达96％。目前，启达制氧机的规格有3L，5L，10L，15L，20L，30L------500L等，很好地满足了客户的需求，赢得了客户的一致赞誉！

2、由广州启达公司提供的“QD系列”变压吸附制氧系统是一种新型高科技制氧设备,它具有设备成本低，体积小、重量轻、操作简单、维护方便、运行费用小、现场制氧快捷、开关方便、无污染等优点。接上电源即可供氧，可广泛运用于工厂化水产养殖，亦可用于石油化工、电炉炼钢、玻璃生产、造纸、制取臭氧、航空航天、医疗保健等行业和领域，设备运行稳定，安全可靠，深受广大用户的青睐。我公司均设有专门的气体领域应用研究队伍，产品范围广，除了涉及工业气体及装置外，其边缘产品及服务获得了较大的市场份额。
3、变压吸附制氧机是以分子筛为吸附剂，利用加压吸附，降压解吸的原理从空气中吸附和释放氧气，从而分离出氧气的自动化设备。分子筛是一种经过特殊的孔型处理工艺加工而成的，表面和内部布满微孔的球形颗粒状吸附剂，呈白色。其孔型特性使其能够实现氧气、氮气的动力学分离。分子筛对O2、N2的分离作用是基于这两种气体的动力学直径的微小差别，N2分子在分子筛的微孔中有较快的扩散速率，O2分子扩散速率较慢。压缩空气中的水和CO2的扩散同氮相差不大。最终从吸附塔富集出来的是氧气分子。

5、工艺流程：
（1）左吸：空气经空压机压缩后，经过除尘、除油、干燥后，进入空气储罐，经过空气进气阀、左进气阀进入左吸附塔，塔压力升高，压缩空气中的氮分子被沸石分子筛吸附，未吸附的氧气穿过吸附床，经过左产气阀、氧气产气阀进入氧气储罐，这个过程称之为“左吸”。持续时间为几十秒。
（2）均压：左吸过程结束后，左吸附塔与右吸附塔通过均压阀连通，使两塔压力达到均衡，这个过程称之为“均压”，持续时间为3~5秒。
（3）右吸：均压结束后，压缩空气经过空气进气阀、右进气阀进入右吸附塔，压缩空气中的氮分子被沸石分子筛吸附，富集的氧气经过右产气阀、氧气产气阀进入氧气储罐，这个过程称之为“右吸”，持续时间为几十秒。
（4）解吸：与右吸同步进行，左吸附塔中沸石分子筛吸附的氧气通过左排气阀降压释放回大气当中，此过程称之为"解吸"。反之左塔吸附时右塔同时也在解吸。
（5）反吹：为使分子筛中降压释放出的氮气完全排放到大气中，氧气通过一个常开的反吹阀吹扫正在解吸的吸附塔，把塔内的氮气吹出吸附塔。这个过程称之为"反吹"，它与解吸是同时进行的。
右吸结束后，进入均压过程，再切换到左吸过程，一直循环进行下去，从而连续产出高纯度的氧气。

5, the process:
Suction in the left (1): after the compression of the air by the air compressor, after dust removal, degreasing, drying the air tank, air intake valve, the left intake valve into the left adsorption tower, the tower pressure, compressed air nitrogen molecules in zeolite molecular sieve adsorption, no adsorption of oxygen through the adsorbent bed, the left middle valve, oxygen production valve into the oxygen tank, this process is called "Left suction. The duration for tens of seconds.
(2) Pressure: left suction end of the process, left the adsorption tower and the right adsorption tower connected by equalizing valve, the pressure to reach equilibrium of the two towers, a process known as "pressure", the duration of three to five seconds.
: Pressure after the end of the compressed air through the air intake valve, the right intake valve into the right adsorption tower (3) The right suction, compressed air, nitrogen molecules are zeolite molecular sieve adsorption, enriched oxygen right middle valve, oxygen production valve into the oxygen tank, a process known as "suck" right duration of tens of seconds.
(4) desorption: the right suction simultaneously, left in the adsorption tower zeolite molecular sieve adsorption of oxygen is released back into the atmosphere through the left exhaust valve buck, this process is called "desorption". On the contrary, the left-right tower when the tower adsorption at the same time also to desorption.
(5) Blowback: zeolite buck release nitrogen emissions into the atmosphere, purge the adsorption tower being desorption of oxygen through the backflush valve is a normally open, the nitrogen of the tower blow the adsorption tower. This process is called "blowback", and desorption at the same time.
After the end of the right absorption into the equalizing process, and then switch to the left suction process, has been the cycle to proceed, and thus a continuous output of high-purity oxygen.
