Thermal induction type coke oven waste heat recovery power generation system based on stabilized power supply circuit
InactiveCN104833228AReduce dosageReasonable designIncreasing energy efficiencyMachines/enginesBrickClosed loop
The invention discloses a thermal induction type coke oven waste heat recovery power generation system based on a stabilized power supply circuit. The system is mainly composed of a coke oven top large pit and oven top quarry tiles covering the surface of the top of the coke oven top large pit. A porose steel plate, a heat insulation plate layer and a porose steel plate are sequentially arranged in the coke oven top large pit from bottom to top. Heat preservation brick layers between the porose steel plates and the heat insulation plate layer are formed by filling the inner gaps inside the coke oven top large pit with heat-resisting sealing slurry. A heat exchanger and an evaporator which form a closed loop are arranged outside the coke oven top large pit. A waste heat power generation system is arranged on the evaporator. A waste heat control circuit is arranged in the waste heat power generation system. A control type power supply circuit, the stabilized power supply circuit and a control type output circuit which are connected in sequence and a thermal induction automatic switching circuit are arranged in the waste heat control circuit.

Trilinear drive type waste heat power generation energy-saving control system based on overvoltage and overcurrent protection
InactiveCN105177205AGuaranteed uptimeEnsure waste heat utilizationCooling devicesIncreasing energy efficiencyOvervoltageTerminal voltage
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.
