The generated dust-containing flue gas has the characteristics of small particle size, large fluctuation degree of flue gas quantity, complex components, large temperature difference and the like, and if effective dust removal operation is not carried out, the dust-containing flue gas can be discharged to an enterprise workshop or an atmospheric environment, so that huge environmental pollution is caused. The existing dust removing equipment mainly comprises a gravity settler, a filtering separator, a cyclone separator, a wet type spray dust remover and the like. The cyclone separator has the advantages of simple structure, compact size, low cost, high separation efficiency, stable performance and the like, and is widely applied to the gas purification process under the working conditions of high temperature, high pressure and the like. The direct current separator has the characteristics of small pressure loss, small equipment volume, large gas flow handling capacity, same gas flow inlet and outlet directions, easiness in combined arrangement of a plurality of separators and the like, and is widely applied to occasions with high particle content and large gas handling capacity.

The blade exit angle is a key parameter of the straight-through separator, which affects the tangential velocity of the dusty gas through the guide blades, directly affecting the separation efficiency. However, the outlet angle of the blade of the existing straight-flow separator cannot be changed, and only can be kept at a certain angle, the adaptability to variable smelting furnace working conditions and fluctuating air quantity is poor, the air quantity can not be well matched with the variable air quantity provided by a dust removal system, and the optimal separation efficiency can not be achieved for different air quantities. The pressure drop losses and the fluctuations in separation efficiency of the direct-flow separator are therefore significant and uncontrollable. On the other hand, most of the separation areas of the current straight-flow separators are hollow cavities and the whole separation area is an annular area. For the cavity type separation area, airflow rotates inside after passing through the flow guide body, a low-pressure area is formed in the middle, so that a boundary layer at the tail of the flow guide body falls off, a counter-pressure backflow area is formed, vortices are generated, the stability of a flow field and the rotation speed of the airflow are reduced, the separation efficiency is reduced, and the pressure drop is increased. For the annular separation area with the central body in the middle, the flow field in the separation area is stable, the airflow keeps a higher tangential speed, particle separation is facilitated, but the distance from the particles to the pipe wall is reduced, the flow area of the separation area is reduced, the axial speed of the airflow is increased, the retention time of the airflow in the separation area is reduced, and the separation of the particles is not facilitated.
