1. Introduction
With the development of industry and the further acceleration of urbanization process, the comprehensive urban environment has been facing new challenges. The improvement of environmental quality has become the main factor to judge the comprehensive achievement of urban construction. In metallurgical steelmaking, electric furnace dust removal is a very important part of environmental protection work. The proper treatment of dust can not only reduce the secondary pollution caused by steelmaking, but also meet the requirements of environmental protection departments on the level of emissions.
Steelmaking electric furnace is the core equipment of steelmaking workshop, and the dust generated in the production process is mainly composed of iron oxide, steel powder and scales. The dust generated by steelmaking electric furnace needs to be removed by dust removal system in accordance with environmental protection requirements. In the current dust removal system of steelmaking electric furnace, there are some technical problems. Relevant enterprises should pay attention to these problems and actively adopt corresponding solutions to improve the dust removal effect.
2. Technical Problems of Steelmaking Electric Furnace Dust Removal System
2.1 Low Dust Removal Efficiency
The dust removal efficiency of steelmaking electric furnace dust removal system directly affects the environmental pollution of steelmaking process. The dust removal system of steelmaking electric furnace has a certain range of dust removal efficiency, but some enterprises have found that the dust removal efficiency of their dust removal system is relatively low, resulting in inefficient dust removal.
2.2 Low Service Life
In the dust removal system of steelmaking electric furnace, in order to ensure the effect of dust removal, the dust removal process often needs frequent replacement of components and regular maintenance of the whole system. However, due to the high coefficient of wear of steelmaking electric furnace dust removal system components and the large amount of dust passing through the equipment, the service life of the dust removal system equipment is relatively shortened.
2.3 High Operating Cost
The dust removal system of steelmaking electric furnace is a complex system composed of dust collector, fan, piping, valve and other components. The frequent replacement of its components and the large amount of electricity consumed in the dust removal process will inevitably lead to high operating costs.
3. Solutions to the Technical Problems of Steelmaking Electric Furnace Dust Removal System
3.1 Increasing the Dust Removal Efficiency
The most fundamental purpose of dust removal is to reduce environmental pollution. Therefore, enterprises should take effective measures to improve the dust removal efficiency of dust removal system. The most direct way is to select high-efficiency dust collectors, use high-efficiency fans, and select reasonable pipelines and valves. In addition, enterprises can choose spraying dust removal systems and replace bag dust collectors to achieve higher dust removal efficiency.
3.2 Strengthening Maintenance Work
In order to improve the service life of dust removal system, enterprises should strengthen the maintenance of dust removal system and its components. According to the actual use of steelmaking electric furnace dust removal system, the corresponding maintenance cycle can be determined, and the workload such as cleaning and maintenance of components should be added to the work organization plans of different positions in the production management system.
3.3 Reducing Operating Costs
The operating costs of dust removal system directly affect the production costs of enterprises, so it is necessary to reduce the operating costs in the process of dust removal. Establish a reasonable dust collection, transportation and discharge pipeline system to reduce the resistance of the pipeline, reduce the power of the fan, optimize the dust collector and fan, and select the low-power motor or frequency conversion motor to reduce the power consumption of the whole system. At the same time, enterprises should also pay attention to the reasonable maintenance of the whole system, reduce unnecessary damage and reduce costs.
4. Conclusion
Dust removal is an important part of environmental protection and steelmaking. The dust removal system of steelmaking electric furnace is an important part of environmental protection work. The technical problems of dust removal system affect the environmental pollution of steelmaking. Enterprises should strengthen the analysis and research of the technical problems of steelmaking electric furnace dust removal system, and take corresponding measures to solve these problems, so as to achieve the reduction of environmental pollution and the optimization of production cost.
