Problems solved by technology
If there is no air filter in a dusty, sandy or cotton-wool environment, the external dust and impurities will be sucked in by the fan and deposited on the fan impeller, affecting the performance of the fan; after entering the burner, due to the The burner is blocked due to the small fire hole; or it is deposited on the wall of the condensing heat exchanger, and it is in a high temperature and high humidity environment for a long time. When the wall-hung boiler is shut down, it is easy to cause mold to nourish and block the heat exchange between the condensing heat exchangers. The space between them will cause poor smoke exhaust and uneven heat exchange during the operation of the wall-hung boiler, which will eventually affect the service life of the wall-hung boiler
However, the air filter of the existing wall-hung boiler is installed on the air intake and exhaust port, which is not easy to replace and clean, and the installation versatility is poor and the cost is high

The invention discloses an air filter for a wall-hung furnace. The air heater is characterized in that the air heater comprises a filter mounting support, a first-stage filtering net and a second-stage filtering element, an air inlet and an air outlet are formed in the filter mounting support, and the second-stage filtering element is arranged in the first-stage filtering net and mounted on the filter mounting support together with the first-stage filtering net so as to space the air inlet and the air outlet. The air filter adopts a two-stage filtration structure, sucked external air is filtered primarily by the primary filtering net and filtered again by the second-stage filtering element mounted inside, thus the filtering effect is good, demounting and cleaning of the interior of the filter structure are facilitated, the whole filter structure can be reused after being cleaned, and thus the using cost is reduced.
Description
technical field [0001] The invention relates to components for a fluid heater, in particular to an air filter for a wall-hung boiler. Background technique [0002] In existing wall-hung boilers, especially for fully premixed condensing wall-hung boilers, during heating operation, the service life of the internal core components of the burner, fan, and condensing heat exchanger is greatly affected by impurities in the external environment. If there is no air filter in a dusty, sandy or cotton-wool environment, the external dust and impurities will be sucked in by the fan and deposited on the fan impeller, affecting the performance of the fan; after entering the burner, due to the The burner is blocked due to the small fire hole; or it is deposited on the wall of the condensing heat exchanger, and it is in a high temperature and high humidity environment for a long time. When the wall-hung boiler is shut down, it is easy to cause mold to nourish and block the heat exchange bet...
