Description
Technical field
The utility model relates to the technical field of boiler, relates in particular to a kind of overfire air fan structure of boiler.
Background technology
In the combustion process of boiler oil, need to provide a large amount of oxygen to realize the abundant burning of fuel by overfire air fan. And can provide whirlwind by overfire air fan, make fully contacting of fuel and air, and realize further burning. Traditional overfire air fan does not filter the air that is sent to boiler, is easy to cause high-temp combustion to produce multiple waste residue. Simultaneously traditional overfire air fan easily causes larger noise in the time of work.
Summary of the invention
The utility model provides a kind of overfire air fan structure of boiler, effectively reduces the noise producing due to overfire air fan work; Meanwhile, reduce harmful dust and other impurity of entering boiler.
In order to solve the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of overfire air fan structure of boiler, comprise gas collection mouth, casing, overfire air fan and snorkel, described gas collection mouth is arranged on the top of described casing, and described overfire air fan is arranged in described casing, described snorkel one end connects described overfire air fan, and the other end is connected to the outside of described casing; Inner side at described casing is provided with muffler, and described muffler comprises at least two-layer acoustical panel of being made up of quieter material.
Further, between described casing and gas collection mouth, be provided with filter.
Further, described filter comprises at least two filter layers.
Preferably, described filter comprises the ground floor screen pack, second layer screen pack and the three layer filtration net that set gradually from top to bottom, and the order number of screen pack reduces from the bottom up gradually.
More preferably, described filter comprises fixed head, and described ground floor screen pack, second layer screen pack and three layer filtration net are parallel to each other, and tilts to be fixed on described fixed head; On the outer surface of described fixed head, between screen pack, locate between two to offer the first opening; Above the contact position of described ground floor screen pack and described fixed head, be provided with the second opening; Arranged outside at described casing has dust-collecting box, dust-collecting box described in described the first opening and described the second open communication.
Preferably, the number of plies of described acoustical panel is two-layer.
Preferably, described gas collection mouth be shaped as back taper.
Preferably, described casing is set to rectangular shape.
Preferably, described casing is made up of stainless steel material.
Preferably, the junction of described snorkel and described casing is provided with sealant.
The utility model provides a kind of overfire air fan structure of boiler, and described muffler comprises at least two-layer acoustical panel of being made up of quieter material, effectively reduces the noise producing due to overfire air fan work. Meanwhile, between described casing and gas collection mouth, be provided with filter, reduce harmful dust and other impurity of entering boiler.
Brief description of the drawings
