fig. 2 is a schematic top view of the tail gas combustion chamber of the petroleum coke rotary kiln of the present invention.
Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.
Examples
As shown in figure 1 and figure 2, the utility model discloses a petroleum coke rotary kiln tail gas combustion chamber, it includes basis 1, frame 2 and combustion chamber, and frame 2 sets up on basis 1, is provided with the combustion chamber in the frame 2, and the one end of combustion chamber is connected with entry flue 5, and the other end of combustion chamber is connected with export flue 8, still is provided with damping structure in the combustion chamber.
In this embodiment, the frame 2 is provided with an inner lining 4 on the inside to prevent the walls of the combustion chamber from melting at high temperatures.
In the embodiment, the damping structure comprises a damping wall 3 and a water-cooling beam 11, the damping wall 3 is arranged at an inlet flue 5 of the combustion chamber and fixed at the bottom of the combustion chamber, and two ends of the damping wall 3 are tightly attached to the left side wall and the right side wall of the combustion chamber; the water-cooling beam 11 is arranged between the combustion chambers and penetrates through the left side wall and the right side wall of the combustion chambers, and the upper parts of the water-cooling beam 11 are tightly attached to the tops of the combustion chambers; the passing time of the dust-containing flue gas in the combustion chamber is prolonged, the air flow rate in a settling chamber at the bottom of the combustion chamber is reduced, the flue gas reaction time is prolonged, dust and volatile matters in the flue gas are fully combusted, the dust, nitrogen oxides and other substances in the flue gas are completely reacted, and the emission of harmful substances in the flue gas is reduced.
