Experimental study on expanded perlite dehumidification within closed space by inside-recycling

Chen Xiaolan,Zhao Ying,Zhu Helin,Sun Gan,Wang Hongliang,Zhang Ruihong

Strategic Study of CAE 2011, Volume 13, Issue 9,   Pages 101-104

Abstract:

The dehumidified adsorption system of expanded perlite in a closed space was designed and orthogonal experiments of three-factor and three-level and single factor for current velocity of wet air, sorbent layer, laid density of sorbent were processed. The effect of the above diversified factor on dehumidification performances was analyzed. The experimental results show that dehumidified velocity increases with air current, and dehumidified time decreases accordingly, higher current velocity of wet air is adopted within a certain scope, which increases dehumidification efficiency. And dehumidification ability improves with adsorbent layer increment. With laid density of adsorbent increment, the ability of heat and mass transfer between wet air and adsorbent grain has improved. Dehumidification velocity increases, and consuming time decreases correspondingly.

The Building of Papermaking Enterprise’s Recycling Economy Evaluation Index System Based on Value Flow

Zhi-fang Zhou,Jing Ou,Sha-sha Wang,Xiao-hong Chen

Frontiers of Engineering Management 2016, Volume 3, Issue 1,   Pages 9-17 doi: 10.15302/J-FEM-2016009

Abstract: At present, the research on circular economy has made a lot of substantive results both at home and abroad. But for the papermaking enterprise, which is the representative of the light industry, few studies have analyzed the evaluation index system of circular economy. Since the current material flow analyses have limitations that the researchers cannot calculate materials with different units. The authors take advantage of the intrinsic correlation between the basic principle of value flow analysis and circular economy, and then analyze the dynamic changes of material flow and value flow through enterprises internal production process. Considering the resource output, the authors set up the layered structure of the evaluation index system, and then preliminarily determine the index form. Next, the authors use the frequency statistics analysis method to adjust indicators, forming a preliminary index system. After that, the principal component analysis and independent analysis are applied for screening. Finally, the authors build a circular economy evaluation index system for papermaking enterprise to provide scientific guidance for the process of circular economy.
