Embodiment Construction
[0021] The flue gas purification reaction tower of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0022] Compared with the flue gas purification technology in the prior art, the flue gas purification reaction tower described in the present invention cancels the structure of the backflow flue gas used in the prior art, and adopts the same side to set the inlet and outlet flue gas ports and utilizes the horizontal The purpose of purifying flue gas is achieved by installing a sealing plate to divide the tower body into two sections. The flue gas purification reaction tower has high reaction efficiency and low cost.
[0023] refer to figure 1 and figure 2 As shown in , the flue gas purification reaction tower includes a reaction tower body 1, an ash hopper 10 installed at the bottom of the reaction tower body 1, an air inlet 11 and an outlet on the same side of the reaction tower body 1. ...

The invention discloses a flue gas purifying reaction tower, comprising a reaction tower body, an air inlet and an air outlet which are arranged on the same side of the reaction tower body, a plurality of reaction chambers inside the tower body, wherein, the reaction chamber is composed of a plurality of guide plates. An air passage is formed between every two reaction chambers, and a purifying chamber is formed by a plurality of reaction chambers. The purifying chamber is divided into a first reaction section and a second reaction section. A sealing plate is arranged laterally on the air passage between the first reaction section and the second reaction section, and a sealing plate is vertically arranged on the air passage interval on the air-inlet side of the first reaction section and on the air-outlet side of the second reaction section, so as to ensure that the influent flue gas flows in an ascending vertical S shape in the purifying chamber and the flue gas is fully reacted with the materials. In addition, a baffle is arranged between two guide plates with sealing plates on the second reaction section, and a water injection device is arranged on the guide plate interval of the air passage. The reaction tower has the advantages of sufficient reaction between the flue gas and the materials, high reaction efficiency, good dust removal results and low cost.
Description
technical field [0001] The invention relates to a flue gas purification device, in particular to a reaction tower for purifying multi-media. Background technique [0002] At present, there are various technologies for desulfurization of sulfur dioxide flue gas, which can be divided into three categories according to the desulfurization method and product processing form, such as dry method, semi-dry method and wet method. There are various methods for desulfurization, such as: [0003] Wet flue gas desulfurization process: [0004] Most of the processes use alkaline slurry or solution as absorbent, among which, the forced oxidation wet desulfurization method using limestone or lime as absorbent is currently the most widely used desulfurization technology. It mainly uses limestone or lime detergent to react with SO2 in the flue gas, and the reaction product calcium sulfate precipitates in the washing liquid, which can be discarded after separation, and can also be recovered...
