AbstractNow, environmental issues have become the iron and steel enterprises have to face challenges. In the iron and steel production, from mining of raw materials preparation, coking, sintering, ironmaking, steelmaking, and so on until the finishing line, smoke and dust exist in almost all of the production line, is not only one of the main sources of pollution, but also a waste of resources, the impact of physical and mental health workers, iron and steel enterprises is the main task of environmental the dust on the domestic iron and steel enterprises governance Shougang iron works with the status of dust control analysis, we can understand that in the dust control Shougang has invested huge in this area, but also to take a lot of advanced dust removal technology, compared treatment results significantly. Especially in the application of airtight cover. However, there are some inadequacies, such as the choice of the collector is still lagging , this research paper will be mainly on the 3rd Shougang blast furnace iron works and a silo hopper dust removal equipment of the transformation, including the working principle of electrostatic precipitator, bag filter, as well as the working principle of a long bag ESP transform low-voltage pulse bag filter. There are 3 high-rise silo hopper and a dust of new technologies and practical management of research, namely, the implementation of the dust source or single-double sealed airtight cover and dust vents mobile devices. More convenient in operation and maintenance, the dust concentration to achieve less than posts lOmg/m3, the concentration of precipitator emissions standard of less than 50mg/ above research and analysis will help future blast furnace of Shougang No. 1,2,4 hopper dust pollution, etc., so that Shougang iron works to improve the environmental words iron works, dust, sealed enclosures, ESP

Title:On the crime of polluting the environment Abstract: with the development of China's economy and the improvement of productivity, environmental pollution is becoming increasingly serious, the judicial practice of the crime of major environmental pollution accident before the difficult to play a role in the "criminal law amendment (eight)" after the introduction of the crime of major environmental pollution accident has made great changes, but there is still insufficient. How to make the crime of the new pollution environment better play a role in the judicial practice is one of the key issues of environmental governance at first chapter is an overview of the crime of polluting the environment, mainly about the concept and characteristics of this crime; the second chapter is the key elements of the crime of polluting the environment of the paper, mainly from the object of the crime, the objective aspect and subjective aspect, the objective aspect of crime, crime analysis results and the type of crime, the subjective aspect of the imputation principle of the key discussion; the third chapter is the identification of environmental pollution crime, mainly discusses the definition of the crime of crime and non crime, illegal disposal, the difference between causation and other crimes, and then discusses the legal punishment of the crime; the fourth chapter is about the suggestions, mainly is to refine the charges and increase the types of words: criminal law; criminal law amendment eight; environmental pollution
