Problems solved by technology

[0004] However, the main problem facing the transformation of the original sintering machine to achieve the purpose of increasing production is the treatment of the external exhaust gas.
The main electrostatic precipitator and desulfurization system supporting the original sintering machine are not suitable for modification. Firstly, the modification cost is very high. Second, it is difficult to pass the audit of the environmental protection department if the amount of exhaust gas is increased.
However, if the main electrostatic precipitator and desulfurization system are not modified, the air volume required for increasing the production of the sintering machine cannot be discharged outside, and the purpose of increasing production is difficult to achieve

Abstract

The invention relates to a capacity increasing improvement system of a sintering machine and a process. The system and process are characterized in that original equipment of the sintering machine is improved, and a smoke circulating system is additionally provided. Therefore, on the condition that a main electric dust remover and a desulphurization system which are matched with an original sintering machine are not modified and the amount of smoke exhausted outside is not increased, the area of the sintering machine is effectively increased, the sintering air volume is increased, sintering negative pressure is improved, and the aim of increasing the yield is achieved.

Description

technical field [0001] The invention belongs to the field of sintering production technology in the metallurgical industry, in particular to a system and technology for increasing production of a sintering machine. Background technique [0002] With the rapid growth of my country's steel production, the resulting environmental problems are becoming more and more serious, especially those containing SO 2 , CO 2 The air pollution caused by exhaust gas has aroused widespread concern. The resource consumption, energy consumption and environmental pollution in the iron and steel production process are mainly concentrated in the ironmaking process (including coking, sintering, pelletizing, and blast furnace), among which the sintering plant has always been a major energy-consuming and polluting household in iron and steel enterprises. It is obvious that the strategic focus of energy saving and emission reduction in iron and steel complexes lies in the sintering plant, and the ne...
