Embodiment 1
[0039] like figure 1 As shown, the main structure of the device of the present invention includes a housing 1 preferably with a rectangular cross-section, an inlet diverging section 2 , a thick-thin separation section 3 , a heteropolar charging section 4 , a turbulent flow condensation section 5 and an outlet tapering section 6 . The inlet gradual expansion section 2 is composed of a constant cross-section flow channel 21 and a gradual expansion cross-section flow channel 22, wherein the constant cross-section flow channel 21 is an elbow structure, which can make the fine particles flow due to the centrifugal force and initially realize the separation of thick and thin, which is beneficial to Enhance the condensation effect of PM2.5. The thick-thin separation section 3 includes a louver baffle 31 composed of 4 plane baffles located on the same plane. The baffle and the flue gas flow form an inclination angle of α=45°, and a certain gap is left between adjacent baffles. The baf...
Embodiment 2
[0041] like figure 2 As shown, the inlet diverging section 2 of the device of the present invention is composed of a constant cross-section flow channel 21 and a diverging cross-section flow channel 22, wherein the constant cross-section flow channel 21 is a straight pipe structure. Particles in the flue gas enter the device through the constant cross-section flow channel 21, and the flow velocity is reduced through the gradually expanding cross-section flow channel. Further, after the flue gas particles pass through the louver 31 of the thick-thin separation section 3, two dust-laden airflows, thick and thin, are qualitatively formed, and the airflow with a higher particle concentration passes through the converging angle 32 to further increase the concentration of particles. The separation baffle 41 in the heteropolar charging section 4 quantitatively divides the dust-laden airflow into thick and thin dust-laden airflows, and most of the PM2.5 is located in the dust-laden a...
