[0002] Waste heat boilers are widely used in various industrial fields, such as steel, chemical industry, ceramics, etc. In these fields, waste heat boilers can effectively utilize industrial waste heat, reduce energy waste, and improve energy utilization efficiency. For example, in the steel production process, high-temperature steel slag can be recycled by waste heat boilers, and its heat can be converted into steam or hot water for use in other processes. In the chemical industry, waste heat boilers can be used to recover and utilize the heat of chemical waste gas to reduce environmental pollution. When the boiler needs to utilize the waste heat, a waste heat utilization structure is required for auxiliary utilization. However, when the existing waste heat utilization structure utilizes the flue gas of the boiler, the dust in the flue gas will adhere to the inside of the equipment, resulting in inadequate utilization of waste heat. The boiler needs to be cleaned manually, and the heat transfer effect of the boiler cannot be ensured, which reduces the use effect of the equipment. In addition, the equipment is generally spliced ​​and fixed by bolt structures, and the flue gas cannot be filtered, which increases the filtering effect and reduces the splicing filtering effect. In addition, when the waste heat is utilized, the hot water cannot be adjusted and discharged, and it needs to be discharged manually, which increases the labor burden and reduces the waste heat utilization effect of the equipment.
