Waste heat monitoring and adjusting method for sintering machine

Abstract

The application discloses a waste heat monitoring and adjusting method for a sintering machine. The method comprises the steps: step 1, collecting devices are arranged; step 2, during sintering, the temperature of each collecting device in the sintering process is recorded, the ambient temperature of the sintering machine is recorded as TE, the temperature below a sintering trolley grate bar is recorded as TB, the temperature of a sintering flue is recorded as TD, the flue gas flow of each collecting device in the sintering process is recorded, the flue gas flow below the sintering trolley grate bar is recorded as VB, the flue gas flow of the sintering flue is recorded as VD, and the sintering flue gas atmosphere composition is recorded; step 3, the waste heat keeping rate of the sintering machine is calculated according to data collected in step 2; and step 4, field workers are guided to adjust production parameters according to the waste heat keeping rate of the sintering machine. According to the waste heat monitoring and adjusting method for the sintering machine, monitoring and early warning can be conducted on the waste heat of the sintering machine, field workers are guided in time to adjust the production parameters and replace maintenance equipment, the waste heat of the sintering machine is improved, the production energy consumption of enterprises is reduced, and considerable additional benefits are created.

Description

technical field [0001] The present application relates to the technical field of sintering production, in particular to a method for monitoring and adjusting the residual heat of a sintering machine. Background technique [0002] In my country, sintering is one of the main means of iron ore powder enrichment and agglomeration, and it is an important part of the whole iron and steel production process. The material handling capacity in the sintering production process ranks second in the whole process of iron and steel joint production, second only to blast furnace smelting. It is one of the processes with the largest material flow and energy flow in the modern iron and steel manufacturing process. Therefore, reducing the energy consumption of the sintering process is an important way to reduce the cost of sintering ore. [0003] The residual heat of the sintered body is closely related to the quality of the sintered ore. The residual heat of the body in the sintered materi...

Problems solved by technology

However, since this invention is based on the oxygen concentration, during the sintering process, the fuel structure in the mixture, the distribution method, and the oxidation of sulfides and nitrogen oxides will all affect the change of the oxygen concentration in the sintering flue gas, which will easily lead to a lot of testing results.
