Description
Technical Field
The utility model relates to a full premix condensing gas heating dual-purpose stove field especially relates to a full premix condensing gas heating dual-purpose stove air filter.
Background
At present, the fully premixed condensing heating dual-purpose furnace sold in the market adopts forced air supply and exhaust closed combustion, and air and fuel gas are mixed according to a certain proportion and then combusted. Because the air in northern China has more dust and impurities, a large amount of non-combustible dust attached to the surface can be accumulated inside the heat exchanger after the machine is used in one heating season, and the combustion efficiency and the heat efficiency of the machine are reduced. Meanwhile, due to the fact that the incombustible dust meets condensed water and can be scaled and blocked between the coils of the heat exchanger, annoying noise and squeal are generated when the machine runs, and later-period use and maintenance cost of a user is increased.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a full premix condensing gas heating dual-purpose stove air filter to solve above-mentioned technical problem.
The utility model discloses a solve above-mentioned technical problem, adopt following technical scheme to realize:
the utility model provides a full premix condensing gas heating dual-purpose stove air filter equipment, includes the bottom plate, circular opening has been seted up to bottom plate central authorities, cylindrical filter screen is installed to the bottom plate top surface, the filter screen outside covers and is equipped with the shell backplate, be provided with a plurality of trompils on the shell backplate, filter screen top and shell backplate top are passed through annular roof and are connected.
Preferably, the filter screen is made of 304 stainless steel.
Preferably, the filter screen is a 50-mesh filter screen.
Preferably, the top surface of the bottom plate is provided with a ring-shaped base, and a sealing ring is arranged above the ring-shaped base.
The utility model has the advantages that:
install on the exhaust smoke pipe of full premix condensing gas heating dual-purpose stove through establishing this device cover, make inside the machine of entering behind the filtration, make the machine also can keep the inside waste residue that does not produce of heat exchanger after using for a long time, make the thermal efficiency, combustion efficiency is not influenced.
