Because of short application and lack of experience, phenomena of thickened or naked of copper stave happen occasionally which influence production severely. So it is important to study the model of forming-accretion on BF copper stave and realize real-time monitoring of forming-accretion on different copper staves. Therefore, mathematic model of calculating accretion thickness by heat flow of BF is proposed, and the calculated results indicate that accretion thickness could be kept at a reasonable range of around 50 mm by controlling heat flux around 22.0 kW/mz. The monitoring program based on the model was applied to a certain BF in China successfully, and it is found that slip of BF near the inner wall is one of most important reasons that cause fluctuation of accretion thickness. During the period of scheduled maintenance of the certain BF, the thickness of accretion measured through the static pressure holes is in good accordance with the value calculated by the monitoring program, so the results calculated by the monitoring program can be used to guide industrial production展开更多

文摘With the implementation of more strict national environmental protection laws,energy conservation,emission reduction and clean production will present higher requirements for sulfur recovery tail gas processing techniques and catalyzers.As for Claus tail gas,conventional hydrogenation catalyzers are gradually being replaced by low-temperature hydrogenation catalyzers.This paper concentrates on the development of technologies for low-temperature hydrogenation hydrolysis catalyzers,preparation of such catalyzers and their industrial application.In view of the specific features of SO2 hydrogenation and organic sulfur hydrolysis during low-temperature hydrogenation,a new technical process involving joint application of hydrogenation catalyzers and hydrolysis catalyzers was proposed.In addition,low-temperature hydrogenation catalyzers and low-temperature hydrolysis catalyzers suitable for low-temperature conditions were developed.Joint application of these two kinds of catalyzers may reduce the inlet temperatures in the conventional hydrogenation reactors from 280℃ to 220℃,at the same time,hydrogenation conversion rates of SO2 can be enhanced to over 99%.To further accelerate the hydrolysis rate of organic sulfur,the catalyzers for hydrolysis of low-temperature organic sulfur were developed.In lab tests,the volume ratio of the total sulfur content in tail gas can be as low as 131×10^(-6) when these two kinds of catalyzers were used in a proportion of 5:5 in volumes.Industrial application of these catalyzers was implemented in 17 sulfur recovery tail gas processing facilities of 15 companies.As a result,Sinopec Jinling Petrochemical Company had outstanding application performances with a tail gas discharging rate lower than 77.9 mg/m^(3) and a total sulfur recovery of 99.97%.
文摘The paper presents the design and field test of a distributed solar PV system for industrial application(DGPVi).DGPVi utilizes HyPV(hybrid PV)system which generates solar power for self-consumption in lighting and air conditioning in a production line of a factory when solar energy is available.It does not feed the excess PV power to the grid.HyPV will be switched to grid power supply when solar energy is not available.A 3 kWp DGPVi is installed in a factory for field demonstration.The test results show that the solar PV power generated can be utilized immediately.The solar energy generation efficiency(kWh/day per kWp PV installation)of DGPVi is close to that of grid-tied PV system without self-consumption and battery storage.The yearly return on investment of DGPVi is 2.0%at the present installation cost or 3.3%at further cost-down cost.The payback time will be 14.3 years at the present installation cost or 12.1 years at cost-down cost.The present study verifies the economic feasibility of DGPVi.
文摘Quality marker(Q-Marker)of traditional Chinese medicine(TCM)is a new concept of TCM quality research.Since it was proposed in 2016,it has aroused wide response from the industry and has become an innovative theory and technical method leading the quality research and quality control of TCM.This paper summarized the core connotation,theoretical basis and innovative value of Q-Marker,proposed the technical strategies and paths of the Q-Marker research,and showed the prospect of its application in the TCM industry.The paper provides references for TCM quality research,quality evaluation,quality control and scientific supervision and has important significance for promoting the quality standard and quality control level of TCM.

文摘Industrial robot application(IRA)provides an opportunity for the low-carbon development of trade.This study focuses on the green revolution of manufacturing export trade,analyzes the mechanism by which IRA affects CO_(2) emissions embodied in manufacturing exports(CIE),and conducts an empirical test based on panel data from 37 countries from 2000 to 2019.This study found that first,IRA can significantly reduce CIE,but there is a U-shaped nexus between the two,which shows a rebound effect.Second,the heterogeneity test demonstrates that in com-parison to both the low-tech and high-tech sectors,IRA in the medium-tech industry can significantly reduce CIE;compared with the low-IRA sectors,the high-IRA sectors exhibit a more obvious reduction.In addition,IRA has a stronger effect on high-carbon-intensity areas.Third,the mechanism test shows that IRA mainly affects CIE through low-carbon technology and productivity effects.Moreover,environmental regulations and the manufacturing in-telligence process positively moderate the nexus between IRA and CIE.Finally,these conclusions provide possible empirical evidence for the smart evolution of the manufacturing industry and the green development of trade.

文摘Blockchain and the programs running on it,called smart contracts,are increasingly applied in all fields where trust and strong certifications are required.Our work focuses on industrial applications of blockchains and not on cryptocurrencies or tokens.We use frameworks to compare public and permissioned blockchains specifically suited for industrial applications.We also propose a complete solution based on Ethereum to implement a decentralized application,putting together in an original way,components and patterns already used and proven.This solution is characterized by a set of validator nodes running the blockchain using Proof-of-Authority or similar efficient consensus algorithms,by the use of an explorer enabling users to check the blockchain state,and the source code of the smart contracts running on it.From time to time,the hash digest of the last mined block is written into a public blockchain to guarantee immutability.The right to send transactions is granted by validator nodes to users by endowing them with the Ethers mined locally.Overall,the proposed approach has the same transparency and immutability as a public blockchain,largely reducing its drawbacks.
