压缩空气干燥净化工艺流程的改进 总被引:1,自引:0,他引:1
1前言我公司空压站有4台3L。-IO/8-G型、1台4L——ZO/8-l型、3台4L-ZO/8型无油润滑空压机,主要供全公司仪表控制用气和生产用气,分为干空气和湿空气两套工艺管线,工艺流程如下:由于多种原因,造成湿空气和干空气产品含湿量较大,对仪表设备的运行非常不利。而且每到冬季,空气管道经常结冰堵塞,危及生产。2压缩空气合湿量大的原因分析①原有干燥器设计进气压为力O.SMPa,但空压机运行多年后,供气压力已难以达到0.SMPa,且生产所需气压大于O4MPa即可,因而干燥后的压缩空气含湿量也难以达到要求。②干燥器设计进气温… 相似文献

在压缩空气溶液除湿实验平台上,分别以LiBr和LiCl水溶液作为除湿剂,实验研究了两种溶液在压缩空气溶液除湿系统中的除湿性能。以溶液表面水蒸气分压力作为比较基准,压缩空气出口含湿量和除湿量作为除湿性能的评价指标,对二者的除湿能力进行比较分析。同时基于压缩空气溶液除湿器传热传质模型,结合实验数据,研究了LiBr、LiCl溶液与压缩空气间的传质系数大小以及变化规律。结果表明:在相同的处理工况下,采用LiCl溶液对压缩空气进行除湿能得到更低的空气出口含湿量和更高的除湿量,LiCl溶液除湿过程的传质系数也高于LiBr溶液,即在压缩空气溶液除湿系统中LiCl溶液具有更优的除湿能力和传质性能。 相似文献

An experimental and theoretical study of the drying of compressed air by a granular silica gel adsorbent was carried out using pressure swing adsorptio This process uses a portion of the dried air expanded to a lower pressure to purge the saturated bed for regeneration purposes. The effect of the volum ratio purge flow/feed flow on the dry air humidity when the process has reached quasi-steady state was investigated over the range 0.85–1.48. These humidities were predicted successfully by a simplified dynamic adsorption model using previously determined equilibrium and rate data. The approach to this steady state was also predicted. The calculated values of the humidity of the outlet regeneration flow indicate the potential of this process for the enrichment of trace adsorbates. 相似文献

As a new compressed air-drying method, the compressed air dehumidification using a pressurized liquid desiccant was proposed in our previous study. The pressurized dehumidifier is a complex and core component of the drying system. The mass transfer performance between the compressed air and LiCl aqueous solution is experimentally studied in a counter-flow pressurized dehumidifier filled with structured packing. The humidity ratio of outlet compressed air, vapor removal of processed compressed air, moisture removal rate, and dehumidification efficiency were selected as the performance indices. The results show that the minimum humidity ratio of processed compressed air could reach 0.23 g/kg under 0.71 MPa. Compressed air-drying performance could be remarkably enhanced through increasing the air pressure and liquid desiccant inlet concentration while the influence of liquid desiccant temperature is negative. Furthermore, in order to ensure high compressed air-drying performance, reduce the power consumption of the air compressor and liquid desiccant pump, and the possibility of carryover, the optimum ratio of liquid to compressed air flow rate is recommended to be around 1.5 under pressure around 0.50 MPa. Meanwhile, the energy consumption for per-gram moisture removal of a liquid-desiccant-based compressed air-drying system can reach 1.42 kJ/g lower than cooling dehumidification under 0.3 MPa, which is 16.0% lower than a compressed air-cooling dehumidification system. 相似文献
