[0002] Boiler flue heat pipe equipment is a complete system that uses heat pipes as the core heat exchange element and integrates flue adaptation structure, waste heat utilization terminal and control components. It is specially designed to recover the waste heat of high-temperature flue gas in boiler flue, and ultimately achieve energy saving, consumption reduction and emission reduction. The former is the complete equipment system, and the latter is the core component of the system. The heat pipe is like the heart, and the equipment is the whole body structure built around the heart.

[0003] Among them, the boiler flue heat pipe energy-saving device is a boiler waste heat recovery equipment designed based on heat pipe technology. Its core function is to recover the waste heat of high-temperature flue gas in the boiler flue and convert it into usable thermal energy (such as preheating boiler feedwater, combustion air, etc.), thereby reducing boiler fuel consumption and improving thermal efficiency. It is a typical key energy-saving and consumption-reducing device in industrial boiler systems.

At the same time, it also cleans the two ends and the four sides of the shell 1 simultaneously, improving the working efficiency and cleaning power of the cleaning component 4.

[0031] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-3 An electromagnetic valve is provided at one end of the air inlet 40 near the limiting tube 41, and the electromagnetic valve is sleeved on the outer wall of the air inlet 40. The electromagnetic valve controls the air intake of the limiting tube 41, reducing dust from entering the device housing 1 and effectively improving the practicality of the device.

[0032] For details regarding the above embodiments, please refer to [link / reference]. Figures 3-5 The bottom of the first positioning plate 42 is provided with a first air outlet 45, and the top of the second positioning plate 43 is also provided with a first air outlet 45, so that the two sets of first air outlets 45 are arranged in convection, which improves the efficiency of cleaning the heat pipe and reduces the accumulation of dust on the inner wall of the device housing 1.

[0033] For details regarding the above embodiments, please refer to [link / reference]. Figures 3-5 The outer wall of the support plate 44 is provided with a second air outlet 46, and there are two sets of support plates 44, which are arranged diagonally.
