Problems solved by technology

In addition, wet desulfurization consumes a large amount of water during the desulfurization process, and will also form serious fog at the end of the flue gas discharge, which is the so-called "white smoke", causing visual pollution
In order to solve this problem, a GGH heater or MGGH heater is installed in the prior art process to heat and discharge the flue gas at the end. Although this measure can improve the visual effect, the installation of GGH and other equipment increases the cost. complicate process layout

Embodiment 1

[0021] combine figure 1 and figure 2 , the present invention is described as follows:

[0022] A flue gas haze reduction and "white elimination" tower, including tower shell 1 and internal components, the tower body is divided into haze reduction part I and heating part II, upper and lower parts, heating part II is on the top, haze reduction part I is on the bottom, heating Part II and haze reduction part I are separated by the position of partition a2; the inner chamber of tower shell 1 of haze reduction part I is sequentially divided into water storage area 3, desulfurization flue gas inlet area 4, washing area 5 and demisting area from bottom to top 6. The space between the desulfurization flue gas intake area 4, the washing area 5 and the demisting area 6 is connected. A scrubber 7 is arranged in the washing area 5. The washing area 5 is an area for purifying and washing the desulfurization flue gas. The washing method is Washing with water to remove the desulfurization...

Embodiment 2

[0028] combine figure 1 , figure 2 , the present invention is described as follows:

[0029] On the basis of Embodiment 1, an air guide plate is provided in the heating zone 11. In this embodiment, the air guide plate is a spiral plate, and the heat exchange tubes 9 pass through the spiral plate. The raw flue gas inlet 13 is set above the heating zone 11, and the raw flue gas outlet 14 is set under the heating zone 11 of the tower shell 1. The raw flue gas enters from the raw flue gas inlet 13, goes down the spiral plate, and finally flows through the Outlet 14 goes out tower shell 1.

Abstract

The invention discloses a haze reducing and white smoke eliminating tower for flue gas. The haze reducing and white smoke eliminating tower comprises tower shell and an internal assembly, wherein thetower body is divided into a haze reducing part on the lower portion and a heating part on the upper portion, the heating part and the haze reducing part use the position of a separation plate a as adividing line, a water storage zone, a desulfurization flue gas inlet zone, a washing zone and a defogging zone are sequentially arranged from bottom to top in the inner cavity of the tower shell, a heating zone is arranged above the separation plate a, a heat exchange pipe is arranged in the heating zone, the heating zone and a purified flue gas outlet zone are separated by a separation plate b,and the defogging zone and the purified flue gas outlet zone are communicated by the heat exchange pipe cavity. According to the present invention, desulfurized flue gas sequentially subjected to hazeremoving and white smoke eliminating so as to achieve clean emission.

Description

technical field [0001] The invention relates to the technical field of flue gas purification equipment, in particular to a flue gas haze reduction and "white elimination" 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 the desulfurization efficiency of this method is relatively ideal, a relatively negative phenomenon will be brought about when this method is used for desulfurization, that is, a large amount of desulfurization agent and desulfurization products will be entrained in the flue gas after desulfurization. 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 desulfurizatio...
