This morning, the Jinling Hall of Nanjing International Exhibition Center accommodated more than 500 people in the conference room. In the second floor exhibition hall, there are a wide range of chemical environmental protection innovation products. Organized by the China Chemical Industry Association and the Jiangsu Provincial Science and Technology Association, co-organized by the Chemical Industry Association of Jiangsu Province, the Jiangsu Provincial Chemical and Chemical Society, and the Jiangsu Provincial Environmental Protection Industry Association, the “2014 National Chemical Industry (Science Park)†is highly concerned by the chemical industry and the environmental protection industry. The "Sewage Treatment Report Conference and Exhibition" was held in Nanjing on the morning of the 17th.
As we all know, Jiangsu Province is a big chemical province in China, and Nanjing City is a famous chemical city. Faced with the implementation of the new environmental protection law, where is the chemical industry suffering from waste water and exhaust gas problems? There are many companies in the chemical park. What should be done as a concentrated area of ​​pollution? Mr. Lu Pengyu, deputy director of safety and environmental protection of Sinopec Jinling Petrochemical Company, and the deputy chief engineer, said at the report meeting that through technical innovation, we implemented the “Clear Water and Blue Sky†project and reached a beautiful vision of harmony with the urban environment. Mr. Zhou Xinrong, the Environmental Protection Bureau of Yangzijiang International Chemical Industrial Park, Zhangjiagang Free Trade Zone, a state-level ecological park, shared with the guests the experience of pollution control in the park. Mr. Zhao Weijian, executive vice president and secretary-general of Jiangsu Province Chemical Industry Association, professor level senior engineer, vice president of Nanjing University of Technology, Professor Xing Weihong, Director of National Special Membrane Separation Engineering Technology Research Center, Mr. Zhu Deming, Jiangsu Province Environmental Protection Bureau Regulation Department, Jiangsu Province Mr. Wu Haisuo, Dean of the Academy of Environmental Sciences, Dean of the School of Environment of Nanjing University of Technology, Professor Xu Yanhua of National Thousand Talents Program, and Ms. Song Xiaohong of Sino-French Water Development Co., Ltd. A total of 12 experts, scholars and entrepreneurs attended the meeting on the chemical industry. It was a wonderful statement on the environmental protection policies and technologies involved in the Chemical Park.
The exhibition attracted more than 200 companies to participate in the exhibition. The exhibition area is over 10,000 square meters. The products displayed include membrane separation, valves, fans, and water treatment chemicals. The three major environmental technology research and development institutions in Jiangsu Province participated in the exhibition. The Jiangsu Provincial Academy of Environmental Sciences, the School of the Environment of Nanjing University, and the School of Environment of Nanjing University of Technology are all special booths that fully demonstrate the scientific research strength of the environmental protection industry in Jiangsu Province. Tianjin Binhai New Area Development Zone Environmental Protection Bureau, Nanjing Chemical Industry Park, Yangzhou Chemical Industrial Park, Shanghai Chemical Concentration Zone, Nantong, Huai'an, Suzhou, Zhenjiang and other chemical parks organized the park enterprises to participate in the conference.
Vice President and Secretary General of the China Chemical Engineering Society, Professor Yang Yuanyi, Professor Level Senior Engineer, Academician Ouyang Pingkai, President of the Jiangsu Science and Technology Association, Ms. Chen Huijuan, Party Secretary and Vice Chairman of the Jiangsu Association of Science and Technology, Deputy Director of Jiangsu Petroleum Institute Chang, Jinling Petrochemical deputy general manager Gao Yue Production and other industry association leaders attended the opening ceremony and delivered speeches, and then visited the exhibition.
The conference played a positive role in the clean production and comprehensive utilization of resources in the chemical industry and the park, raising awareness of environmental protection and promoting industrial upgrading.
Boiler auxiliary equipment mainly includes water supply equipment, ventilation equipment, fuel supply, slag removal and dust removal equipment, steam and water pipes and accessories, detection instruments and automatic control equipment.
1. Water supply equipment
It is composed of water treatment equipment, water supply tank and feed pump 24. Water treatment equipment is used to remove impurities in water, such as oxygen, calcium and magnesium ions, to avoid scaling and corrosion on the inner wall of steam boiler, and to ensure the quality of boiler water supply. The treated boiler feed water is lifted by the feed water pump and then sent to the upper drum through the economizer.
2. Ventilation
The ventilation equipment includes air supply fan, induced draft fan and chimney. Its function is to provide air for mule fuel combustion and lead out combustion product flue gas from the boiler, so as to ensure the normal combustion, and make the flue gas wash the heating surface at the necessary flow rate of 7a68696466fe78988e69d8331333433626465 to strengthen heat transfer. Finally, the stack with a certain height will exhaust the smoke to the atmosphere to reduce the smoke pollution and improve environmental health.
3. Fuel supply, slag removal and dust removal equipment
This is for conveying fuel to boiler, removing ash and purifying flue gas. Belt conveyor, ash conveyor, ash truck and dust remover, etc. For boilers that need to be pre processed with fuel, fuel preparation such as screening, crushing and coal grinding shall also be included. In addition, the dust remover or flue gas desulfurization and denitrification device installed in the flue at the tail of the boiler is an indispensable auxiliary equipment to reduce the smoke pollution and protect the environment.
4. Check instruments and automatic control equipment
In addition to water level gauge, pressure gauge, safety valve and other instruments installed on the boiler body, in order to supervise, regulate and control the safe and economic normal operation of the boiler equipment, a series of instruments, automatic boiler feed water regulating device, automatic fuel combustion control device, etc. are often installed. Some boiler rooms are also equipped with industrial television and remote control device and even more modern automatic control system, more Scientific supervision. Control boiler operation.
Boiler auxiliary equipment, not every boiler is equipped completely, but with the boiler capacity, type, fuel characteristics and combustion mode as well as water quality characteristics and many other factors to adapt to local conditions, adapt to the times, more practical requirements and objective conditions.
