Co- and tri-generation system based on absorption refrigeration cysle: a review

ABSTRACT

Absorption refrigeration system is a heat-driven refrigeration system, which has a good application prospect in co- and tri-generation system, and is of great significance to energy conservation and emission reduction. In this paper, the combined power and cold system the combined power and cooling system and the combined cold cooling, heat, and power system based on absorption refrigeration are reviewed. Working fluid of absorption refrigeration cycle, different configurations, system performance, main application fields, and economic considerations of co- and tri-generation systems were focused in this review. This paper will be useful for the researchers to have a more comprehensive understanding of the application and development prospect of co- and tri-generation systems based on Absorption Refrigeration Cycle.     

吸附法去除钨冶炼废水中的砷

采用一种自主研制的新型吸附剂KL-As01及其专用活化剂KL-AsH1深度去除某钨冶炼企业焙烧尾气碱洗废水和外排混合废水中的砷。在小试、中试研究的基础上,进一步设计了400 m~3/d外排混合废水的处理工艺路线。结果表明,废水经KL-As01吸附剂和KL-AsH1活化剂协同处理后,出水中砷质量浓度小于0.1 mg/L,满足GB 8978—1996《污水综合排放标准》中总砷的排放指标,估算运行成本为5.86元/t。该方法具有处理工艺简单、处理结果稳定、设备占地面积小、易操作、处理成本较低等优点,具有良好的发展和应用前景。     

基于社会认知理论的事故体验对矿工不安全行为影响研究

为了研究事故体验对矿工不安全行为的余效效应,基于社会认知理论框架,建立了安全氛围调节作用下的事故体验对矿工不安全行为的假设模型,收集308名陕西和甘肃等地矿山企业一线工作人员有效调查问卷,采用结构方程(SEM)和层次回归的方法对假设模型进行了验证.结果表明:个体的事故体验通过风险感知和安全态度的中介作用负向影响矿工的不安全行为;组织安全氛围在风险感知对不安全行为的影响中有负向增强的调节作用,在风险感知和事故体验对安全态度的影响中具有正向增强的调节作用.

Using multi-integrated biomarker indexes approach to assess marine quality and health status of marine organism: a case study of Ruditapes philippinarum in Laizhou Bay,China

With the progress of technology and the deepening of understanding of biological monitoring, much more attention has been paid to the multiple evaluation of marine pollution monitoring. In view of this, our study aimed at establishing a multi-integrated biomarker indexes approach to evaluate marine condition systematically and comprehensively. In the current study, sampling was conducted in Laizhou Bay, China (S1, S2, and S3) in May, August, and October of 2015. And then, multi-integrated biomarker indexes approach was applied to assess marine PAHs pollution, select appropriate biomarkers, and evaluate marine environmental quality and health status of the clams of Ruditapes philippinarum. As the results showed, S2 was the most PAHs-polluted site while S1 was the least polluted site, and the levels of tPAHs in seawater and sediments ranged from 69.78 to 315.30 ng/L and 163.19 to 565.17 ng/g d.w., respectively. And all three sampling sites had different sources of PAHs. IBR represented DNA damage (F value), the expression of SOD, EROD activity, GST activity, and LPO could be served as biomarkers to monitor the PAHs pollution in Laizhou Bay. And MPI suggested the quality of all three sites: S1 was generally favorable, S2 was moderately polluted, and S3 was lightly polluted. BRI values showed that the order of health status of R. philippinarum was S1?>?S3?>?S2.
