The invention relates to the technical field of ferrous metallurgy sintering processes, in particular to a sintering machine energy-saving system and method based on circular cooler tail section hot air recycling coupling oxygen-enriched combustion, and the sintering machine energy-saving system comprises a low-temperature hot air recycling unit, an oxygen-enriched mixing unit, a discharge detection unit and an intelligent regulation and control unit. Low-temperature hot air at the tail section of an annular cooler is taken and introduced into a closed hood of a sintering machine mineral aggregate layer through the suction force of an induced draft fan, the oxygen enrichment degree of the hot air in the closed hood is increased, and the uniform oxygen-enriched hot air passes through the sintering mineral aggregate layer and is combusted and completely reacted with the solid fuel-coke powder in the sintering mineral aggregate layer through negative pressure driving of an air bellow below the material level. The method has the beneficial effects that the reaction speed is high, the theoretical combustion temperature is high, CO emission is reduced while sintering of the sintered ore is assisted, energy is saved, and the yield is increased.

This utility model relates to the field of pulverized coal injection machine technology and discloses a pulverized coal injection machine feeding device, including a base plate, a shock-absorbing bracket fixedly installed on the base plate, and a dual-outlet pneumatic feeder fixedly installed on one side of the base plate. The dual-outlet pneumatic feeder contains an impeller. This pulverized coal injection machine feeding device uses a single power source (a fan controlled by a frequency converter) to drive feeding, grinding, and injection. Compared to traditional pulverized coal injection machines with multiple power sources, energy consumption can be reduced by more than 35%, effectively reducing production costs. Simultaneously, the simplified structure reduces the number of components, making installation simpler and troubleshooting easier during maintenance, shortening maintenance time by 80%. This reduces downtime due to maintenance, improves production efficiency, and ensures that the fan speed matches the grinding speed, making the grinding process more stable and improving the uniformity of injection, which is beneficial for the complete combustion of fuels such as coal and improves combustion efficiency.
