Technical Field
The invention relates to the technical field of purification and dust removal, in particular to a secondary cyclone separation component flowing from a multi-cone to a single cone and a dust collector.
Background
In the existing secondary separation assembly based on the cyclone separation principle, the primary structure is usually composed of one or more cones, and the secondary structure is usually one cone or a plurality of cones with the same size or smaller sizes attached to the primary structure (for example, the primary structure is composed of one cone, and the secondary structure is composed of a plurality of cones surrounding the primary cone); the dusty airflow flows to the secondary cyclone cone after being purified from the cone, and the clean airflow purified by the secondary cyclone cone is converged together and flows out of the air outlet; taking the first-stage cone as an example, and the second-stage cones as a plurality of cones, the airflow flowing out of the air outlet of the first-stage cone is divided into a plurality of branches to flow to each air inlet of the second-stage cone respectively; in order to achieve high separation efficiency of the secondary cone, the wind speed flowing into the secondary cone is required to be extremely high so as to achieve sufficient centrifugal force, so that the size of the secondary cone is usually much smaller than that of the primary cone (if only one secondary cone has one cone, the size of the secondary cone is equivalent to that of the primary cone), which causes that the air flow rubs with the inner wall surface of the cone more violently in the motion process of the secondary cone, the on-way resistance and local resistance loss are very large, the pressure drop loss of the current secondary cone structure is very large, and the noise is very high.

Furthermore, a branch pipeline is connected to the primary conical air inlet pipe; the tail ends of the plurality of branch pipelines are connected with the shunt pipeline; an air inlet is arranged on the shunting pipeline.
Furthermore, the number of the primary cones is n, and the length, width and height of the secondary cone are 1-n/2 times of those of the primary cone.

The invention has the following beneficial effects:
1. based on the scheme that the multi-cone trend is towards the single cone, air flows respectively flowing out of the multi-cone are uniformly distributed and flow in the circumferential direction when flowing to the single cone, so that the air entering the secondary cone is uniform, the intensity of turbulence is reduced, and the separation efficiency of the secondary cone is improved;
2. because the primary cone exists as the primary dust removal, the high dust removal efficiency is not needed, the high wind speed is not needed, the primary multi-cone flows to the secondary single cone, and the wind speed in the secondary cone is higher than that of the primary cone even if the size of the secondary cone is properly increased, so that the higher centrifugal force is generated, and the separation efficiency of the secondary cone is improved; the size of the secondary cone is larger, so that overlarge resistance loss is avoided;
3. because only one secondary cone is provided, even if one or more of the primary cones has reduced efficiency, the gas flowing out after the purification of the secondary cone can also keep extremely high dust removal efficiency; if the total dust removal efficiency is reduced, except the extreme condition that the efficiency of a certain primary cone is greatly reduced, the secondary cone is usually checked in a targeted manner, so that the maintenance is convenient;
4. the structure is simple, the pressure drop loss is low, the noise is low, the efficiency durability is strong, and the maintenance cost is low.
