The technical scheme of the fire nozzle structure of the dual firing chamber of two sections of incinerators of swinging of the present utility model, by increasing by a precombustion chamber between the burner in dual firing chamber and quirk, changed the angle of the nozzles of dual firing chamber, the flame of Shi Cong dual firing chamber nozzles ejection mixes with certain adverse current angle mutually with the air-flow of rotary kiln, can offset the impact of flame to the refractory material of the furnace wall of dual firing chamber, extend the service life of refractory material, thereby can extend the service life of whole equipment.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the furnace cavity structure of two sections of incinerators of existing swinging;
Fig. 2 is the schematic diagram of fire nozzle structure of the dual firing chamber of two sections of incinerators of swinging of the present utility model;
Fig. 3 is the structural representation of the precombustion chamber in the fire nozzle structure of dual firing chamber of two sections of incinerators of swinging of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 2 and Fig. 3, the fire nozzle structure of the dual firing chamber of two sections of incinerators of a kind of swinging of the present utility model, comprises burner 1 and quirk 2, and wherein, the outside that is tightly connected between burner 1 and quirk 2 is rolled the precombustion chamber 3 being welded by steel plate.
This precombustion chamber 3 is that conical conical cavity 31 and one section of outer surface and inner cavity surface are columniform cylindrical cavity 32 and form by one section of outer surface; The front end of the minor diameter of conical cavity 31 is connected with burner 1, and the anterior inner cavity surface of this conical cavity 31 is the face of cylinder, and the rear portion inner cavity surface of this conical cavity 31 is taper seat; The rear end of cylindrical cavity 32 is connected with quirk 2, and the rear end face of this cylindrical cavity 32 is inclined-plane.The lining thickness of conical cavity 31 is greater than the lining thickness of cylindrical cavity 32 in addition.Precombustion chamber 3 all adopts steel disc to add graphite flexible sealing with the sealing of burner 1 and quirk 2.
In one embodiment, the length of precombustion chamber 30 is 0.8～1.2 meter, make nozzle effectively extended 0.8～1.2 meter to the distance of the furnace wall, opposite of dual firing chamber, wherein, the total length of conical cavity 31 is 470～490 centimetres, the length of the anterior cylindrical cavity face of conical cavity 31 is 150～160 centimetres, and the length of the central shaft of cylindrical cavity 32 is 490～510 centimetres, and the gradient of the rear end face of this cylindrical cavity 32 is 1 ︰ 5.6～5.8.
