[0001] The invention relates to the technical field of heat energy recovery, and in particular to a flue waste heat recovery system for boiler water preheating with a heat exchange function. Background Art

[0002] Traditional boiler systems generate a large amount of waste heat during the combustion process. This waste heat is usually discharged into the atmosphere through the flue, resulting in energy waste. In order to improve energy efficiency and reduce energy consumption, it is necessary to recycle this waste heat. The flue waste heat recovery system for boiler water preheating is an efficient energy utilization system. Through the heat exchange principle, the high-temperature flue gas in the boiler flue is heat exchanged with the boiler water, so that the boiler water is preheated before entering the boiler body. It aims to recover the waste heat in the boiler flue and use it to preheat the boiler water, thereby improving energy efficiency.

Summary of the invention

[0009] Preferably, the flue waste heat recovery module consists of a flue, a water storage space, a circulating water component and a temperature control unit. The water storage space is arranged on the outer wall of the flue, and is used to wrap and directly contact the flue gas to absorb the waste heat. The circulating water component is connected to the water storage space, and is used to circulate the water in the water storage space to absorb and transfer the waste heat of the flue gas to the boiler water. The temperature control unit is used to monitor the working status of the boiler and adjust the boiler settings according to the preset optimal energy-saving parameters to maximize the utilization of energy.

[0011] Preferably, the heat pump auxiliary heating module includes a heat pump unit, which is connected to a circulating water component. When the waste heat transferred by the circulating water component is insufficient to heat the boiler water to a predetermined temperature, the heat pump unit automatically starts to provide additional heating energy for the boiler water.

[0012] Preferably, the heat exchange module consists of an air energy recovery device and a heat exchanger. The air energy recovery device is used to recover heat energy in the workshop and perform on-site cooling as needed to improve the workshop environment.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is connected to the circulating water component through a heat pump unit. The waste heat recovery module absorbs the heat energy in the flue gas and transfers it to the boiler water. The temperature of the boiler water rises during the preheating process, which reduces the boiler's demand for natural gas and energy consumption. The heat energy in the flue gas is converted into usable heat energy, and the flue waste heat is effectively recovered to reduce energy waste and thus improve energy efficiency. The heat pump auxiliary heating module monitors and adjusts the optimal settings of the boiler to ensure that it achieves the most energy-saving effect, and is used to provide additional heating when the waste heat is not enough to heat the boiler water to a predetermined temperature. The system efficiently utilizes the boiler flue waste heat and reduces energy consumption to achieve maximum energy utilization and cost reduction. The coordinated work of multiple modules achieves efficient energy recovery and utilization.

[0017] 2. The present invention is connected to the air energy recovery device through a heat exchanger. The cooling water absorbs the heat generated by the drawing drum and reduces its temperature during the circulation process. The heated cooling water exchanges heat energy with the flue waste heat recovery module through the heat exchanger. The cooled cooling water re-enters the drawing water cooling module for continued circulation, and at the same time absorbs workshop heat for cooling the drawing drum. The heat exchange module recovers air energy and blows out cold air for on-site cooling, which reduces the workshop temperature, absorbs workshop heat and improves the hot workshop environment, and improves the working comfort of the staff. The drawing water cooling module ensures a good cooling effect during the drawing process of the drum, improves product quality and production efficiency, and the recycling of cooling water for the drawing drum reduces energy waste, improves energy utilization efficiency, reduces environmental pollution, and further improves the workshop environment and drawing cooling effect.
