The specific embodiment
As shown in Figure 1, the environment-protection boiler of burning solid particle of the present invention comprises body of heater 1, is arranged on the burner hearth 2 in the body of heater 1, the lower end of burner hearth 2 is provided with fire bars 3 and slag notch 4, be provided with feed pipe 5 in the upper end of burner hearth 2, the inner of described feed pipe 5 is communicated to the upper end of burner hearth 2, the outer end of feed pipe 5 is arranged on the outer wall of body of heater 1, and is provided with fire door; The outer periphery of described burner hearth 2 is equipped with annular air duct 6, and the inwall of described annular air duct 6 is close on the outer wall of burner hearth 2.The inwall of annular air duct 6 is provided with the through hole 7 that is communicated to burner hearth 2 inner chambers, and the inner of blast pipe 8 is communicated with annular air duct 6, and the outer end of blast pipe 8 is arranged on the outer wall of body of heater 1, is used to connect equipment such as air blast; The top of burner hearth 2 is provided with secondary combustion chamber 9, the top of described secondary combustion chamber 9 is provided with upper tank 10, be provided with chimney 11 in the described upper tank 10, the lower end of described chimney 11 is communicated with secondary combustion chamber 9, the upper end of chimney 11 is positioned at the top of upper tank 10, absorbs the temperature of flue gas in the chimney 11 by the water in the upper tank 10.
The below of burner hearth 2 is provided with flame storehouse 12, and slag notch 4 is arranged on the bulkhead in flame storehouse 12; Be provided with lower header 14 between the periphery of burner hearth 2 and body of heater 1, be provided with flue 13 in lower header 14, the upper end of described flue 13 is communicated with secondary combustion chamber 9, and the lower end of flue 13 is communicated with flame storehouse 12.Lower header 14 around be arranged on burner hearth 2 around, burner hearth 2 is surrounded, the water in the lower header 14 just can fully absorb the heat in the burner hearth.Certainly, for the water in upper tank 10 and the lower header 14 is connected, the water pipe that is communicated with both can also be set between upper tank 10 and lower header 14.
As shown in Figure 4, the layering setting from top to bottom of described through hole 7, included angle A between the radius in the center line of through hole 7 and burner hearth 2 cross sections is 30 °-85 °, and is equating with the angle between the radius in through hole 7 its center lines of one deck and burner hearth 2 cross sections.Like this, the wind that through hole 7 blows out shape in the shape of a spiral in burner hearth 2 forms stable, orderly air-flow.Certainly, the setting of through hole 7 also can be adopted structure as shown in Figure 5, makes the center line of through hole 7 point to burner hearth 2 centers.
As a plurality of different embodiment of the present invention, the center line included angle A of the through hole 7 of different layers can be equal fully, the technical scheme that also can adopt included angle A to increase or reduce gradually gradually between different layers to produce the spiral air flow of different-effect, adapts to fuel of different nature.
As shown in Figure 3, as another embodiment of the present invention, the outer end of described feed pipe 5 is connected with auger conveyer 15, can constantly fuel be sent into burner hearth by auger conveyer 15 like this.
