| In recent years, the state and society pay a great attention on the atmospheric environment, and the standards of flue gas emission in the enterprise are more strictly treated. More accompany makes greater efforts to reduce pollution and sulfur dioxide emissions with the development of enterprise. In this paper, through the transformation for desulphurising solutions and the correlation control system of the boiler of one cigarette factory, it describes flue gas treatment and control system with engineering practice.The mainly contents are as follows:1 A large amount of in formations are consulted in this paper, and situations of air pollution in our country and the application of gas desulphurization technology at home and abroad are reviewed and analysised.At the same time, it introduces the standard of air pollution and the method of the flue gas desulfurization technology. Their characteristics have been analyzed and compared, and the scope of application has been explained.2. The theory of desulphurization technology program is analysis, and the scope of application is analysis and companioned. Combined with the actual use of the boiler plant and flue gas emissions of the treatment program selection, the method is used in dealing with lime (limestone)-gypsum wet flue gas desulphurization system. Select the processing equipment and choose the FS-04 regulate flow tower Integrated System.3 For the previous monitoring system can not meet with the status of current requirements. It must upgrade the system in order to satisfy the need of expansion the boiler and flue gas treatment for dynamic monitoring and centralized control. According to the appropriate equipment, the modification scheme for corresponding equipment and the specific implementation methods are proposed.In conclusion, this paper analyses and discusses the principles of flue gas desulphurization control method. With the actual needs of the factory from the relevant equipment selection, as well as related control system implementation, this paper successful implements the equipment selection and the engineering applications. It will provide a better reference for the future engineering applications. |
