Embodiment Construction

[0016] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the embodiments and accompanying drawings. The embodiments are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0017] see figure 1 , figure 2 and image 3 , a high-efficiency cyclone dust removal demist dehydration desulfurization tower, the chimney of the desulfurization tower is provided with four layers of centrifugal cyclone separators 1 and a water retaining ring 2 sequentially from the bottom up.

[0018] The centrifugal cyclone separator includes a central shaft 11 and a plurality of guide vanes 12 in the shape of a truncated isosceles triangle, and one end of the guide vanes rotates 30 degrees clockwise from the axial direction along the central axis to the central axis. The other end of the guide vane is fixed to the inner wall of the chimney ...

Abstract

The invention discloses a high-efficiency cyclone dedusting, demisting, dehydration and desulfurization tower. The chimney of the desulfurization tower is provided with multi-layer centrifugal cyclone separators and a water retaining ring sequentially from the bottom up. The centrifugal cyclone separators It includes a central shaft and a plurality of truncated isosceles triangular guide vanes, one end of the guide vane is fixed to the central shaft by rotating clockwise at an angle of 30-45 degrees along the central axis, and the other end of the guide vane It is fixed to the inner wall of the chimney, and the end of the guide vane fixed to the central axis is the top of the guide vane in the shape of a truncated isosceles triangle, and the end fixed to the inner wall of the chimney is the bottom end of the guide vane in the shape of a truncated isosceles triangle . The invention not only has good effect of dust removal and fog removal, but also avoids the formation of gypsum rain, and the downward moving water droplets will be washed by the centrifugal cyclone separator to avoid clogging of the centrifugal cyclone separator, without frequent replacement and washing, and is convenient to use.

Description

technical field [0001] The invention relates to a desulfurization tower, in particular to a high-efficiency cyclone dust removal demist dehydration desulfurization tower. Background technique [0002] The exhaust gas after coal combustion in traditional coal-fired power plants is discharged from the chimney after limestone-gypsum wet desulfurization. Discharge, falling to the ground to form "gypsum rain". [0003] In order to avoid "gypsum rain", flat plate demisters and ridge demisters are generally selected, but the effect is not good. Contents of the invention [0004] The invention provides a high-efficiency cyclone dedusting, fogging, dehydration and desulfurization tower, which ensures that the water content of the outlet flue gas is lower than that of the existing desulfurization tower by more than 60%, eliminates gypsum rain, and removes white mist. [0005] In order to solve the above problems, the technical solution adopted in the present invention is as follow...
