Embodiment 1

[0022] combine figure 1 , figure 2 , Figure 5 and Figure 6 , the present invention is described as follows:

[0023] A flue gas desulfurization and haze reduction tower, including a tower shell 1 and internal components, the inner cavity of the tower shell 1 is from bottom to top, followed by a slurry area 2, an air intake area 3, a desulfurization area 4 and a washing area 5, and the slurry area 2 communicates with the air intake area 3, a partition 6 is set between the air intake area 3 and the washing area 5, and the partition 6 isolates the air intake area 3 and the washing area 5, and the desulfurization area 4 is in the desulfurization cylinder 7 on the partition 6. The slurry area 2 is the area used to store and collect the desulfurization slurry, also called the slurry pool; the intake area 3 is the area where the flue gas enters the desulfurization haze reduction tower; the desulfurization area 4 is the area where the desulfurization slurry contacts the flue gas...

Embodiment 2

[0030] combine figure 1 , figure 2 , image 3 and Figure 4 , the present invention is described as follows:

[0031] On the basis of Embodiment 1, in the washing area 5 and above the desulfurization cylinder 7, a shielding device, called a water blocking cap 15, is added to prevent the water sprayed by the scrubber 10 from entering the desulfurization cylinder 7, thereby Drop into final slurry pool. The water blocking cap 15 is arranged on the upper part of the desulfurization cylinder 7 , leaving a gap so that the flue gas enters the washing area 5 from the desulfurization cylinder 7 . In the present embodiment, a double-spherical water blocking cap 15 is adopted.

Abstract

The invention discloses a flue gas desulfurization and haze reducing tower, which comprises a tower shell and an internal assembly, wherein a slurry zone, a gas inlet zone, a desulfurization zone anda washing zone are sequentially arranged from bottom to top in the inner cavity of the tower shell, the slurry zone and the gas inlet zone are communicated, a separation plate is arranged between thegas inlet zone and the washing zone, and separates the gas inlet zone and the washing zone, the gas inlet zone and the washing zone are communicated through the inner cavity of the desulfurization cylinder on the separation plate, and the inner cavity of the desulfurization cylinder is a desulfurization zone. According to the present invention, flue gas can be subjected to desulfurization and dustremoving purification in the flue gas desulfurization and haze reducing tower so as to achieve the purposes of desulfurization and haze reducing and complete clean emission.

Description

technical field [0001] The invention relates to the technical field of flue gas purification equipment, in particular to a flue gas desulfurization and haze reduction tower. Background technique [0002] The existing flue gas desulfurization methods mainly include wet desulfurization and dry desulfurization. Among them, the limestone gypsum method is the main method for wet desulfurization. This method is mature and has been adopted by most of the current flue gas desulfurization processes. use. Although this method has high desulfurization efficiency in application, it is easy to cause a large amount of desulfurization agent and flue gas entrainment of desulfurization products. Practice and research have shown that the aggravation of smog in the current environmental pollution is directly related to the use of a large number of wet desulfurization methods. In the prior art, there is no integrated equipment that can prevent desulfurization agent and desulfurization product...
