Abstract
The invention discloses a trilinear drive type waste heat power generation energy-saving control system based on overvoltage and overcurrent protection. The system is composed of a blast furnace body (1), a power generation system (12), a steam utilizing device, two or more annular superconduction heat exchange rings (2) which are annularly arranged along the side wall of the blast furnace body (1) in a layered mode, a waste heat control and treatment system and the like. The waste heat control and treatment system comprises a diode rectifier U, a voltage stabilization and transformation circuit, a three-terminal voltage stabilizing control circuit and a trilinear driving circuit. The trilinear drive type waste heat power generation energy-saving control system is characterized in that an overvoltage and overcurrent protection circuit is further connected in series between the voltage stabilization and transformation circuit and the trilinear driving circuit. According to the trilinear drive type waste heat power generation energy-saving control system, due to the annular superconduction heat exchange rings which are embedded in the side wall of the blast furnace body and annular pipeline systems corresponding to the annular superconduction heat exchange rings, hot water produced after heat exchange can be led out in a concentrated mode, and heat exchange efficiency and cooling efficiency are improved; besides, due to the fact that the superconduction heat exchange rings are applied twice to be overheated to 400 DEG C, cooling waste heat can be used for generating electricity.
Description
technical field [0001] The invention relates to a high-efficiency power generation system for cooling heat of a blast furnace, in particular to a three-linear drive waste heat power generation energy-saving control system based on overvoltage and overcurrent protection. Background technique [0002] During the blast furnace production process, the cooling of the furnace wall requires a large amount of water to take away the heat to reduce the temperature of the furnace wall, so as to meet the process temperature requirements of the normal production of the blast furnace. The waste heat taken away by the cooling of the blast furnace and the surface heat dissipation ratio of the blast furnace wall account for 5% and 0.5% of the total heat consumption of the blast furnace respectively. Based on the simple calculation that 400-800Kg of coke is needed to produce one ton of pig iron, there are about 20-40Kg of coke produced Thermal energy is dissipated in the form of cooling water...
