Description
Heater Driving Apparatus Using Waste Heat Recovery Power Generation The present invention relates to charging control through waste heat recovery power generation and a heater driving device using the same. More specifically, it relates to a heater driving device using waste heat recovery power generation that can improve the heating effect of a heater by efficiently performing heat exchange through proper utilization of waste heat. A conventional waste heat recovery ventilation device is a device that recovers thermal energy or cooling energy from discarded water or air through heat exchange, and may include a heat exchanger and a heater for heat exchange. The heat exchanger induces heat exchange between the outdoor air and the indoor air by bringing the outdoor air circulating through the ventilation system into indirect contact. The heater heats the cold air introduced from the outside to prevent the indoor temperature from dropping suddenly. However, conventional devices had a limitation in that heat exchange was not properly performed, requiring the use of large-capacity heaters. Therefore, there is a need to develop a heater drive system with a new configuration that can improve the heating effect of the heater by properly utilizing waste heat to enable efficient heat exchange. Related prior art includes Korean Patent Registration No. 10-0803108 (Title of invention: Waste heat recovery ventilation device for use with small capacity heaters). FIG. 1 is a schematic diagram of a heater driving device using waste heat recovery power generation according to one embodiment of the present invention. Figure 2 is a control flow diagram of the device of Figure 1. The advantages and/or features of the present invention and the methods for achieving them will become clear by referring to the embodiments described below in detail together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below but may be implemented in various different forms. These embodiments are provided merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims. Throughout the specification, the same reference numerals refer to the same components. Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. FIG. 1 is a schematic diagram of a heater driving system using waste heat recovery power generation according to one embodiment of the present invention, and FIG. 2 is a control flow diagram of the device of FIG. 1. As illustrated in these drawings, a heater driving device using waste heat recovery power generation according to one embodiment of the present invention may include a body part where heating is performed, a waste heat recovery part for recovering waste heat, an ESS charging part for charging power from the recovered waste heat, and a control part for controlling each component for driving the heater. First, the control unit of the present embodiment detects the temperature of the preheating section and the heat treatment section as shown in FIGS. 1 and 2, controls waste heat generation, controls power, and controls the heater. This will be described later. Referring to FIG. 1, the body portion may include a first body member in which preheating is performed and a second body member in which heat treatment is performed. Waste heat can be recovered from this body portion. In particular, heat treatment is performed in the second body member, which is operated in a nitrogen gas atmosphere to prevent oxidation of the heat-treated metal, and is heated to 500°C or higher depending on the heat treatment conditions, thereby recovering waste heat to produce electricity. A temperature sensor is installed in the first body member and the second body member to measure the internal temperature in real time and send the measurement information to the control unit. In addition, the temperature sensor is connected to the temperature detection unit, and by sending the measurement information from the temperature detection unit to the control unit, the heater driving unit can be driven by the control unit. Heaters are installed in the first body member and the second body member to apply heat to the first body member and the second body member. Since the first body member is a preheating section, for example, one heater may be installed, and since the second body member is a heat treatment section, multiple heaters may be installed. The heaters are connected to a heater driving unit, so that the heaters can be selectively driven by the heater driving unit. And it is connected to the second body member and the waste heat recovery unit, that is, the waste heat recovery heat exchanger, so that heat can be exchanged in the heat exchanger. A waste heat recovery heat exchanger can
