On July 17th, the intelligent online monitoring and optimization operation technology of textile printing and dyeing wastewater treatment jointly completed by Shenyang Institute of Automation Research Institute of the Chinese Academy of Sciences Guangzhou (hereinafter referred to as “Shenyang Automation Institute Guangzhou Branchâ€) and Hutai (Panyu) Textile Printing and Dyeing Co., Ltd. The project passed the technical results appraisal organized and presided by the Guangzhou Science and Technology Innovation Committee.
Experts in the identification group include experts from South China University of Technology, South China Normal University, Guangdong Provincial Academy of Environmental Sciences, Zhujiang Institute of Water Conservancy, Guangzhou Institute of Microbiology, Guangdong Institute of Automation, and Guangzhou City Environmental Monitoring Center. composition. The appraisal committee heard the development work and technical summary report made by the project leader, reviewed relevant information, and watched the system demonstration.
After discussion and discussion, the appraisal team believed that: a set of intelligent on-line monitoring and optimization operation technical system for textile printing and dyeing wastewater treatment established in this project, from the system real-time online monitoring, online optimization operation and expert knowledge base assisted operation three levels of textile printing and dyeing wastewater treatment The process is monitored throughout the process and systematically optimized.
Developed a biodegradable on-line monitoring device for wastewater based on microbial respiratory status, realized on-line analysis of key process indicators such as biodegradability of sewage and microbial activity, improved the control level of drug consumption and energy consumption, reduced costs, and ensured the system Effluent water quality is stable. The expert group of the identification team unanimously believed that the overall technology of the project has reached the domestic advanced level, reached the leading domestic level in biochemical control, and agreed to pass the identification of scientific and technological achievements.
Teflon is Polytetrafluoroetylene, referred to as Teflon, PTFE, F4, etc.It is also known as Teflon, Teflon, Teflon, Teflon and so on because of its pronunciation.Polytetrafluoroethylene (ptfe) is a kind of plastic, which is used to manufacture heaters. It has been successfully used in chemical equipment heating. It has the characteristics of multi-layer and three-dimensional heating.
The working pressure, working temperature, heat transfer coefficient and installation method of the Teflon Heater vary greatly according to different types, different shell materials and different thermal media.The chemical properties of teflon are very stable and the corrosion resistance is especially good.The surface of the teflon tube is smooth and moderately flexible, so it is not easy to scale due to the slight vibration when using it.The teflon heater is small in size and compact in structure. The heat transfer area per unit volume of the equipment is more than 4 times of that of the shell heater.Flexible teflon tubes work safely under shock and vibration of fluids, and the tubes can be made into special shapes as needed.Teflon has low thermal conductivity, poor mechanical properties than metal, and is not resistant to high temperature.The use of small diameter, thin wall, although the thermal conductivity and mechanical properties of compensation, but can only be used in the case of low pressure and low temperature.The production of teflon steam heater and teflon hot water heater has become more and more mature, and widely used in chemical industry, medicine, pickling and other corrosive industries.
