[0001] The utility model relates to the technical field of waste heat recovery from sewage sources, in particular to a waste heat recovery device for industrial waste water. Background Art

[0002] The treatment and resource utilization of industrial wastewater is a critical issue in the current environmental protection field. With the acceleration of industrialization, the discharge of industrial wastewater has increased annually, resulting in not only a waste of water resources but also a serious threat to the ecological environment. Industrial wastewater typically contains large amounts of organic matter, heavy metals, and other pollutants, and its temperature is often higher than that of the surrounding environment. These characteristics give industrial wastewater a significant thermal energy potential during treatment. Effectively recovering this waste heat would significantly improve the energy efficiency and economic viability of wastewater treatment.

[0003] However, the existing equipment has low heat recovery efficiency when treating high-temperature wastewater and fails to fully utilize the heat in the wastewater. Some waste heat recovery systems are complex in design and have high maintenance costs, which limits their application in small and medium-sized industrial enterprises.

[0004] Therefore, based on the above technical problems, it is necessary for technicians in this field to develop a sewage source waste heat recovery device suitable for industrial wastewater. Utility Model Content

[0020] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. For those skilled in the art, the present invention can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0021] like Figure 1 、 Figure 2 and Figure 3 As shown, the present invention provides a technical solution for a waste heat recovery device for industrial wastewater, including a waste heat recovery tank 1. The waste heat recovery tank 1 serves as the main body of the entire device, and its interior is divided into three areas: a high-temperature waste heat recovery area 131, a low-temperature waste heat recovery area 132, and a discharge area 133 by partition 1 11 and partition 2 12. The height of partition 1 11 is greater than that of partition 2 12. This design ensures that after entering the waste heat recovery tank 1, the high-temperature waste water first flows through the high-temperature waste heat recovery area 131, and as the temperature decreases, it flows through the low-temperature waste heat recovery area 132, and finally enters the discharge area 133 for discharge, thereby achieving hierarchical heat recovery and improving the efficiency of heat energy recovery.

[0022] Both the high-temperature waste heat recovery zone 131 and the low-temperature waste heat recovery zone 132 are equipped with exchange assemblies. These assemblies primarily consist of exchange tubes 31, which run through both zones and perform heat exchange with the wastewater. An input control valve 32 is installed at the input end of the exchange tubes 31, while an output control valve 33 is installed at the output end. By controlling the opening and closing of these two valves, heat input and output can be precisely controlled, further improving the accuracy and efficiency of heat recovery.

[0023] To facilitate monitoring of temperature changes within the high-temperature waste heat recovery zone 131 and the low-temperature waste heat recovery zone 132, observation windows 14 are installed on adjacent walls of these two zones, and thermometers 2 are installed adjacent to these windows 14. The thermometers 2 monitor the temperatures within these zones in real time and transmit this data to the control system, allowing staff to promptly monitor temperature changes and make appropriate adjustments.

[0024] The top of the waste heat recovery tank 1 is equipped with multiple wastewater inlet pipes 16, which communicate with the high-temperature waste heat recovery area 131 and are used to introduce high-temperature industrial wastewater into the waste heat recovery tank 1. The lower outer wall of the waste heat recovery tank 1 is equipped with multiple wastewater discharge pipes 15, which communicate with the discharge area 133 and are used to discharge the wastewater after the waste heat recovery treatment.

[0025] In addition, the partitions 11 and 12 are detachably connected to the waste heat recovery box 1, and the interfaces are sealed. This design not only facilitates assembly and maintenance of the device, but also effectively prevents heat leakage and improves the efficiency of waste heat recovery.

[0026] The waste heat recovery device for industrial wastewater provided by the utility model realizes efficient recovery and utilization of waste heat in industrial wastewater through scientific and reasonable structural design, which is of great significance for improving the energy efficiency and economy of wastewater treatment.

[0027] In this embodiment, the valve on the sewage inlet pipe 16 is opened, allowing high-temperature industrial wastewater to begin flowing into the waste heat recovery tank 1. As the wastewater flows in, it first enters the high-temperature waste heat recovery zone 131. Here, the medium (such as cooling water or other heat carrier) within the exchange tube 31 exchanges heat with the high-temperature wastewater, absorbing heat from the wastewater. During this time, personnel monitor the data transmitted by the thermometer 2 through the control system to observe temperature changes within the high-temperature waste heat recovery zone 131. When the temperature reaches a preset value, the control system automatically adjusts the opening of the input control valve 32 and the output control valve 33 to maintain stable heat exchange efficiency.

[0028] As the wastewater cools in high-temperature waste heat recovery zone 131, it overflows through partition 11 and flows into low-temperature waste heat recovery zone 132. Here, the remaining heat in the wastewater is further recovered. Similarly, staff closely monitor temperature changes in this zone and fine-tune valves through the control system to ensure efficient heat recovery.

[0029] Finally, the wastewater after the waste heat recovery treatment enters the discharge area 133 and is discharged through the sewage discharge pipe 15. At this point, most of the heat in the wastewater has been recovered, realizing the reuse of energy.
