Detailed Description

Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.

Referring to fig. 1 and 2, the utility model provides a high-efficiency centrifugal dynamic shielding demister for a desulfurizing tower, which comprises a cylinder 1, wherein a shaft support 3 is arranged at the center of an inner cavity of the cylinder 1, the shaft support 3 is connected with the cylinder 1 through a rotating shaft 2, 3 rotational flow plates 4 are assembled on the outer wall of the shaft support 3, the number of external blades of the rotational flow plates 4 is 18, the elevation angle of each blade is 25 degrees, a dust-removing demister 5 is assembled above the shaft support 3, and the dust-removing sulfur-nitrate demister 5 is connected with the shaft support 3 through a silk thread demister combination assembly 6;

referring to fig. 3, the silk thread defogging plate assembly includes a supporting beam 61, a first-level silk thread defogging plate 62, a second-level silk thread defogging plate 63, and a top rotating motor 64, wherein the first-level silk thread defogging plate 62 and the second-level silk thread defogging plate 63 are respectively and fixedly connected to two sides of the cylinder 1, the top rotating motor 64 is fixedly connected to the outer wall of the second-level silk thread defogging plate 63, and a dedusting sulfur-nitrate defogger is fixedly connected to the top of the supporting beam 61.
