Abstract

The invention discloses a desulfuration method of flue gas and composite circulating convective absorption tower, which comprises the following steps: letting the flue gas enter the reaction region at the bottom of tower; lifting the purified gas continually; obtaining the purified flue gas through middle reaction region within hopper liquid-collecting reflux device and composite controllable blocking device; draining the fog through upper reaction region. The composite circulating convective absorption tower is characterized by the following: the paste reaction pond is set in the bottom of tower cylinder with gas outlet on the top; the tower cylinder contains paste spray device, hopper liquid-collecting reflux device, composite controllable blocking device, limestone paste spray device, lower defroster and upper defroster; the plaster paste outlet is set in the bottom of paste reaction pond tower cylinder.

Description

Technical field: [0001] The invention relates to a flue gas desulfurization method and desulfurization equipment. It is especially suitable for flue gas desulfurization produced in the production of large-scale thermal power plants, coking plants and other enterprises. Background technique: [0002] With the development of economy and the continuous increase of energy consumption, SO 2 Emissions are increasing day by day, and the problem of acid rain has become more and more serious. Acid rain has seriously endangered human health and living environment. Whether it is the national government, or the existing power generation, coking and other enterprises that are running or are about to be built, as well as relevant departments and technical experts, the SO 2 Both the total amount of emissions and the concentration of emissions have attracted great attention. A lot of fruitful work has been done and some achievements have been made, but the problem is still serious. [00...
