TECHNICAL FIELD

[0001] The present application relates to the field of filtering devices, in particular to a filtering flue for a wall-mounted boiler. BACKGROUND

[0002] Wall-mounted boilers, as a common household heating device, have been widely used in recent years. It produces heat by burning natural gas or other fuels, thereby providing hot water and heating for users. However, in actual use, wall-mounted boilers generally have the problem of insufficient combustion, resulting in the emission of a large amount of harmful gases and particulate matter, not only wasting energy, but also seriously polluting the environment. In addition, the traditional wall-mounted boiler lacks effective flue gas treatment measures in design, so that these pollutants are directly discharged into the atmosphere, further exacerbating environmental pollution problems.

[0003] To address this challenge, existing technical means mainly focus on improving combustion efficiency and increasing post-processing equipment. On the one hand, by optimizing the design of the combustion chamber, the combustion efficiency of the fuel is improved, and the harmful substances produced by incomplete combustion are reduced. On the other hand, some wall-mounted boilers are equipped with simple filtering devices, such as metal mesh or ceramic filter elements, to intercept some larger particulate matter. In addition, some wall-mounted boilers use water cooling or air cooling methods to try to reduce the emission of pollutants by cooling flue gas.

[0004] Although these methods improve combustion efficiency and reduce emissions to some extent, there are still obvious shortcomings. Since the filtering device is located inside the flue, flue gas particles accumulate for a long time, making maintenance and cleaning more troublesome and increasing the user's use cost. Therefore, how to design an efficient and easy-to-maintain filtering flue for a wall-mounted boiler has become a technical problem to be solved. CONTENT OF THE INVENTION
