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...
