Top is provided with pressure gauge, and primary air fan is connected by process pipe with burner hearth bottom, and primary air fan passes through purging First air
Pipeline is connected with annular bellows, and flue one end is arranged above central tube, and the other end is connected by air-introduced machine with chimney.
Further, blow device is connected to form at four purging wind inlets with annular bellows, each to purge at wind inlet
Electric control valve is respectively arranged with, the pipeline axial positions of four pipes of blow device set observation panel, observation panel respectively
Front end is respectively arranged with ball valve.
Further, the cyclone separator tapering gradient is 70 °.
Further, one section of the nearly primary air fan of process pipe is provided with isolating door.
Further, flue is internally provided with superheater, economizer, air preheater and deduster.
The utility model has the advantages that：
1. by increasing blow device, the mobility of circulating ash in cyclone separator is added, eliminates cyclone separator
Tapering dust, slagging phenomenon.
2. the utility model is by cyclone separator technological transformation, changing cyclone separator tapering structure, reducing
The flow resistance of circulating ash in cyclone separator.

Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.
As depicted in figs. 1 and 2, the utility model discloses a kind of modified form biomass boiler Cyclonic separating apparatus, including
Feeding warehouse 1, burner hearth 2, cyclone separator 4, central tube 3, annular bellows 5, blow device 10, primary air fan 11, pressure gauge 15,
Flue 13, air-introduced machine 16, chimney 20 and process pipe etc., feeding warehouse 1 is connected with burner hearth 2 by pipeline, and burner hearth 2 passes through pipe
Road is connected with cyclone separator 4, and central tube 3 is arranged on the center of top of cyclone separator 4, the lower end tapering of cyclone separator 4
Periphery is provided with annular bellows 5, and the bottom of annular bellows 5 is provided with four molecular blow devices 10 of pipe, the top of annular bellows 5
Pressure gauge 15 is provided with, primary air fan 11 is connected by process pipe with the bottom of burner hearth 2, and primary air fan 11 is by purging with once
Wind pipeline 8 is connected with annular bellows 5, and the one end of flue 13 is arranged at the top of central tube 3, and the other end passes through air-introduced machine 16 and cigarette
