[0023] The present invention also provides an operating method for a carbon black reactor burner having an air supply guide structure, based on the above-mentioned carbon black reactor burner having an air supply guide structure, comprising the following steps:

[0024] S1. Install the combustion box at the bottom of the carbon black reactor through the connecting seat; connect the air inlet pipe to the external gas supply equipment, and the gas enters the combustion chamber through the air inlet pipe; connect the main air duct to the external air supply equipment, and the outside air enters the combustion chamber through the main air duct;

[0025] S2. After the gas enters the gas chamber through the gas inlet pipe, it is evenly dispersed into the interior of each gas injection pipe under the action of the trapezoidal gas grooves on each gas balancing plate;

[0026] S3. Use an igniter to ignite the gas ejected from the jet pipe. The flame formed by the combustion of the gas passes through the flame holes on the flame dividing plate. The outside air enters between the first air outlet plate and the second air supply plate through the main air duct and is ejected through each air supply flat tube. The cooperation of the air supply flat tube and the arc-shaped guide plate causes the outside air to collide with the flame to form a high-temperature flame, thereby heating the reactor.

[0027] Compared with the prior art, the beneficial effects of the present invention are embodied in the following aspects:

[0028] First, the burner structure of the present invention is rationally designed. During the operation of the burner, the airflow entering the burner is guided so that the airflow collides with the flame to form a high-temperature ion flame, which is beneficial to improving the heating uniformity of the reactor and making the materials in the reactor react more fully, thereby improving the carbon black production efficiency and reducing the loss of raw materials.

[0029] Secondly, during operation, the burner of the present invention can not only adjust the direction of the air supply flat tubes, but also use a movable pull rod to pull the sliding baffle to move on the rotating adjustment disk, so that the air supply volume of the corresponding air supply flat tubes can be individually adjusted. Moreover, when a specific sliding baffle is closed, the air supply of the air supply flat tubes can be directional, which greatly improves the reliability of the burner of the present invention.

[0030] Third, the present invention utilizes a rotating motor to drive the drive turntable to rotate. During the rotation of the drive turntable, the arc-shaped pressure block compresses the piston pressure rod to move on the corresponding compression cylinder, and the piston plate is used to inject the air inside the compression cylinder into the main air duct, which not only increases the air intake of the main air duct, but also avoids hot air backflow to damage the air supply component.

7. A method for operating a carbon black reactor burner with an air supply guide structure, based on the carbon black reactor burner with an air supply guide structure according to claim 5, characterized in that: The following steps are involved: S1. Install the combustion box (1) at the bottom of the carbon black reactor via the connecting seat (10); connect the air inlet pipe (20) to an external gas supply device, and the gas enters the combustion chamber (12) through the air inlet pipe (20); connect the main air duct (40) to an external air supply device, and the outside air enters the combustion chamber (13) through the main air duct (40); S2. The driving motor (24) is used to drive the power gear (240) to rotate. The power gear (240) and the driving gear disc (230) are meshed to allow the rotating sleeve (23) to drive the various gas balancing discs (21) to rotate inside the gas chamber (12). When the rotating sleeve (23) drives the gas balancing discs (21) at both ends to rotate, the outer gear ring (231) on the rotating sleeve (23) drives the inner gear ring (25) to rotate in the opposite direction through the planetary gear (26). At this time, the gas balancing disc (21) located in the middle rotates in the opposite direction outside the rotating sleeve (23), so that the gas passes through the trapezoidal gas grooves (22) on each gas balancing disc (21) in sequence and is evenly distributed to the inside of each gas injection pipe (30). S3, using an igniter to ignite the gas ejected from the jet pipe (30), the flame formed by the combustion of the gas passes through the flame hole (310) on the flame separation plate (31), the outside air enters between the first air outlet plate (41) and the second air supply plate (42) through the main air duct (40), and is ejected through each air supply flat pipe (43), and the air supply flat pipe (43) and the arc-shaped guide plate (32) cooperate to make the outside air collide with the flame to form a high-temperature flame, thereby heating the reactor; S4. According to the distribution of the flame inside the flame hole (310) on the flame dividing plate (31), the adjusting rod (440) is used to drive the rotating adjusting plate (44) to rotate on the main air duct (40). At this time, the rotating adjusting plate (44) can drive each air supply flat tube (43) to swing simultaneously, thereby adjusting the airflow direction in the area above the flame dividing plate (31).
