4Simulation and experiment of six-bed PSA process for air separation with rotating distribution valve显示文摘In this work,a six-bed pressure swing adsorption(PSA)process was investigated to produce medical oxygen from air,which uses the combination of six-way rotating distribution valve and PSA and has the main advantage of effectively saving space compared to the traditional two-bed or four-bed PSA process and can obtain greater productivity.The mathematical model of adsorption beds was developed based on the separation mechanism and the interaction among different equipment.Moreover,a pilot-scale device has been constructed to verify the accuracy of mathematical model by experiment.The oxygen product conformed to the medical standard(>93%(vol))with a recovery of over 57%.Some related parameters were also discussed in detail,such as step time,ratio of length to the diameter,flow rate of product.Tao Tian Yayan Wang Bing Liu Zhaoyang Ding Xinxi Xu Meisheng Shi Jun Ma Yanjun Zhang Donghui Zhang 2022Chinese Journal of Chemical Engineering2022,35,2:1
5Expert consensus on irrigation and intracanal medication in root canal therapy显示文摘Chemical cleaning and disinfection are crucial steps for eliminating infection in root canal treatment. However, irrigant selection or irrigation procedures are far from clear. The vapor lock effect in the apical region has yet to be solved, impeding irrigation efficacy and resulting in residual infections and compromised treatment outcomes.Xiaoying Zou Xin Zheng Yuhong Liang Chengfei Zhang Bing Fan Jingping Liang Junqi Ling Zhuan Bian Qing Yu Benxiang Hou Zhi Chen Xi Wei Lihong Qiu Wenxia Chen Wenxi He Xin Xu Liuyan Meng Chen Zhang Liming Chen Shuli Deng Yayan Lei Xiaoli Xie Xiaoyan Wang Jinhua Yu Jin Zhao Song Shen Xuedong Zhou Lin Yue 2024International Journal of Oral Science2024,16,1:0
