Description

Novel adjustable cyclone device of rotary kiln combustor

Technical Field

The technology belongs to the field of clinker calcining equipment, particularly relates to an adjustable cyclone device of a novel pulverized coal burner in a rotary cement kiln, and provides a novel device with multiple air channels, multiple nozzles and a linkage adjustable cyclone angle.

Background

The cement rotary kiln is different from other thermal devices in that certain requirements are made on the flame shape of a pulverized coal burner, and the reasonable temperature distribution of each section in the kiln can be ensured only by the proper flame shape. The ideal flame shape is to remain circular in any cross-section, with the longitudinal cross-section being a "mallet" of appropriate thinness. The shape of the flame can make the whole burning zone have strong and uniform heat radiation, thereby forming a compact and stable kiln skin in the burning zone, improving the quality of the kiln, reducing the heat consumption, prolonging the service life of the rotary kiln refractory brick, protecting the burner nozzle from being burnt out too early and balancing the temperature of the barrel.

The conventional rotary kiln multi-air-channel combustor has the advantages that the arrangement of each air channel is basically consistent among manufacturing plants, and the conventional rotary kiln multi-air-channel combustor sequentially comprises outer axial flow air, coal air, rotational flow air and a central channel/ignition channel (the central channel is not used generally) from outside to inside. The coal pipes in the arrangement mode are arranged between the outer axial flow wind and the rotational flow wind, after the coal powder is sent out of the combustor, the coal powder is immediately diffused by the rotational flow wind along a certain angle, when the rotational flow strength of the jet flow center is increased to a certain value, a backflow area with an annular vortex shape is established at the jet flow center, and flame parameters such as flame stability, combustion strength and the like depend on the size and strength of the vortex. When the rotational flow strength is increased, the attenuation of each velocity component of the jet beam along the axial direction is increased, the range is shortened, the diffusion angle is increased, the corresponding flame shape is thick and short, otherwise, the flame shape is slender.

In order to adjust the swirling air angle, a swirler is generally arranged in a swirling air channel, however, a traditional swirler is a semicircular spiral groove channel forming a certain angle with an axis, and after a burner is manufactured into a finished product, the spiral groove is fixed and unchangeable and cannot be adjusted according to needs. In fact, due to different fuels and the variation of combustion value during the use process of the burner, the corresponding angle adjustment of the swirler for controlling the direction of the swirling air is required to ensure that the flame of the burner can be in the optimal combustion state.

In view of the above, there is a need for improvement of a multi-channel burner of a rotary kiln, and a swirl device with adjustable flame shape of the burner is designed to simplify the flame shape adjusting process, enlarge the adjusting range, make flame adjustment more diversified, and be suitable for different working conditions, wherein long flame can be adjusted to be longer, short flame can be adjusted to be shorter, and the thickness, angle and quadrant of flame can be adjusted freely.
