Description

Technical Field

[0001] The utility model relates to the technical field of smoke purification, in particular to a cone bucket fluidization device for a cyclone dust collector. Background Art

[0002] The cyclone dust collector consists of an air inlet pipe, an exhaust pipe, a cylinder, a cone, an ash hopper and a bracket. Its working principle is that the dust-laden gas enters the dust collector tangentially through the air inlet pipe, changes from linear motion to rotational motion, and spirals downward under the influence of fluid pressure and the shape of the inner wall of the cylinder, moving toward the cone. The dust-laden gas generates centrifugal force during the rotation process, causing the dust particles heavier than the gas to overcome the air flow resistance and move toward the wall of the device. Once the particles come into contact with the wall, they lose their inertial force and slide down the wall surface driven by gravity and the rotating fluid, and fall into the ash hopper. After the rotating descending airflow reaches a certain position near the bottom of the cone, it turns back from the bottom to the top in the dust collector in the same direction of rotation, spirals upward on the inside of the downward airflow, and is finally discharged from the exhaust pipe together with some unseparated fine particles. The streamlines of the fluid in the cyclone are similar to double helices. The airflow spiraling downward on the outer side is usually called the outer vortex, and the airflow spiraling upward on the inner side is called the inner vortex.

[0003] In the prior art, most of the dust contained in the flue gas of a general coal-fired boiler is spherical, with a smooth surface and small pores; a small part of it collides with each other in a molten state and adheres to each other, becoming honeycomb-shaped composite particles with a rough surface and many edges and corners. Its water content is very low and its adhesion is not strong. When the cyclone dust collector is used in the flue gas treatment system of a coal-fired boiler, the problem of poor ash discharge from the cone bucket generally does not occur. However, if it is used in the flue gas treatment system of a waste incinerator, dust "bridges" and "arches" will be generated during long-term operation, resulting in poor ash discharge. The main reasons are as follows:

[0004] 1. The composition of urban domestic waste is complex and can be roughly divided into two parts: combustible and non-combustible. The combustible part includes waste paper, rags, bamboo, leather, plastic, and animal and plant residues, while the non-combustible part includes waste metal, sand, glass and ceramic fragments. After burning, the smoke is mostly fibrous or flocculent, with high cohesion, especially poor low-temperature fluidity.

[0005] 2. The lime slurry (Ca(OH)2) sprayed into the deacidification reaction tower reacts with acidic gases such as sulfur dioxide (SO2) and hydrogen chloride (HCL) in the flue gas to produce calcium sulfite (CaSO3) and calcium chloride (CaCl). These two substances are easy to absorb moisture, have poor fluidity, and even form on the inner wall of the cone bucket, resulting in "bridge" and "arch" phenomena, resulting in poor ash discharge.
