The invention discloses an alarming type sintering waste heat power generation system based on a voltage-stabilizing power circuit. The alarming type sintering waste heat power generation system based on the voltage-stabilizing power circuit comprises a sintering machine hot flue gas system, a hot exhaust gas waste heat utilizing system, and a sintering waste heat power generation thermodynamic system. A voltage-stabilizing power output system connected to the output end of a turbogenerator is further arranged in the sintering waste heat power generation thermodynamic system, and the voltage-stabilizing power output system comprises a temperature alarming circuit, the voltage-stabilizing power circuit and a storage battery or electric equipment connected with the voltage-stabilizing power circuit. The voltage-stabilizing power circuit is composed of a voltage-stabilizing circuit and a power circuit. By means of the sintering waste heat power generation system, the stability of the product is improved, the service life of the product is prolonged, the circuits running in the product are added and modified, and the situation that because voltage fluctuation is too high, the storage battery or the electric equipment is damaged is avoided.
Description
technical field [0001] The invention belongs to the technical field of sintering waste heat power generation in iron and steel plants, in particular to an alarm-type sintering waste heat power generation system based on a voltage-stabilized power supply circuit. Background technique [0002] In the process of iron and steel production, the energy consumption of the sintering process accounts for about 10% of the total energy consumption, ranking second only to the iron-making process. In the total energy consumption of the sintering process, nearly 50% of the heat energy is discharged into the atmosphere in the form of sensible heat from the flue gas of the sintering machine and the exhaust gas of the cooling machine. Power generation by sintering waste heat is an important measure for steel plants to achieve energy conservation and emission reduction. [0003] The sulfur content of the flue gas in the non-desulfurization flue pipe of the sintering machine is low, and the fl...
