Problems solved by technology

For the calcium method, "gypsum rain" will be formed, and for the ammonia method, "ammonia rain" will be formed. These flue gas condensate not only affect the surrounding environment, but also cause problems such as surrounding corrosion

Embodiment 1

[0028] like Figure 1~5 As shown, this embodiment includes a tower body 1, a stirring assembly 2 and a demisting assembly 3, an air inlet and a liquid inlet are respectively opened on the side wall of the tower body 1, and an exhaust port is opened on the top of the tower body 1 The stirring assembly 2 is installed on the side wall of the tower body 1, the defogging assembly 3 is fixed on the inner top of the tower body 1, and the stirring assembly 2 includes a box body 21, a motor 23 and a fixed cylinder 24 arranged on the side wall of the box body 21 , the motor 23 is arranged on the fixed cylinder 24, and the output end of the motor 23 continues to extend after penetrating the side wall of the box body 21, and the driving wheel 22 is installed on the extension section of the output end of the motor 23, and the fixed cylinder 24 is far away from the box body One end of 21 is equipped with a flange 27, and also includes a linkage shaft 26 arranged in the fixed cylinder 24, on...

Embodiment 2

[0036] like figure 1 , 5 As shown, this embodiment further includes a sealing ring 210 disposed on the end surface of the extension section of the sleeve 28 , and the inner peripheral wall of the sealing ring 210 is in contact with the outer peripheral wall of the linkage shaft 26 . In the desulfurization tower, the blades 211 and part of the interlocking shaft 26 are placed in the slurry, and the sleeve 28 and the interlocking shaft 26 are flexibly connected, that is, under the premise that the set sealing ring 210 can ensure the normal rotation of the interlocking shaft 26, the sleeve 28 and The connection gap of the linkage shaft 26 is sealed, that is, the inside of the sleeve 28 is isolated from the outside, so as to prevent slurry from entering the connection gap, thereby ensuring the normal rotation of the linkage shaft 26 .

[0037] This embodiment also includes a rubber ring 25 disposed on the inner peripheral wall of the fixing cylinder 24 , and the inner peripheral ...

Abstract

The invention discloses a power plant desulfurization tower comprising a tower body, a stirring assembly and a demisting assembly; the side wall of the tower body is respectively provided with an air inlet and a liquid inlet, and an exhaust port is arranged in the top of the tower body; the stirring assembly is mounted on the side wall of the tower body; the demisting assembly is fixed on the top end of the interior of the tower body. Boiler flue gas is treated successively by the stirring assembly and the demisting assembly, fog in flue gas floating upward in the tower body can be completely adsorbed on the side wall of a wave-folded plate, and thus the flow quantity of the fog overflowing along a smoke vent is reduced, and impact of condensate water overflowing from the chimney smoke vent on the surrounding environment is reduced.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a desulfurization tower of a power plant. Background technique [0002] In the prior art, since the flue gas that has undergone wet scrubbing and desulfurization can be treated as saturated steam, its water content is relatively high. Even after demisting and dehydrating by two-layer demisters, it is easy to form " Chimney rain", especially for the desulfurization tower with integrated flue gas tower, after the flue gas is washed and deacidified by the desulfurization tower, it enters the chimney through the flue, and then is discharged into the atmosphere, while the desulfurization chimney mostly adopts a brick-cut structure with special anti-corrosion inside treatment, and the height of the chimney itself is more than 50 meters (required for environmental protection emissions), the cost is very high, and the cost of the chimney is even higher than that of the desulfurization tower...
