Embodiment Construction
[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, and the mode of the present invention includes but not limited to the following embodiments.
[0018] The purpose of this embodiment is to provide a desulfurization tower for desulfurization of coal-fired flue gas, such as figure 1 As shown, the desulfurization tower includes a tower body, and a rectification device 2, a spray layer 1, and a demister 5 arranged sequentially in the tower body from bottom to top, as well as a flue gas inlet 3 and a flue outlet arranged on the tower body 6. The bottom of the tower body is also provided with an agitator 7, and the agitator 7 has fan-shaped stirring blades; the agitator can blow off the flue gas entering the desulfurization tower, so that it can evenly enter the desulfurization area of the desulfurization tower, and the The original flue gas is fully broken to form multiple streams of flue gas in contact with ...

The invention discloses a desulfurizing tower for coal-fired flue gas desulfurization. The desulfurizing tower comprises a tower body, and a rectifying device, a spraying layer and a demister which are sequentially arranged in the tower body from bottom to top, as well as a flue gas inlet and a flue outlet arranged on the tower body, wherein a stirrer is arranged at the bottom of the tower body; the flue gas inlet is formed between the rectifying device and the stirrer; the flue outlet is formed in the top of the tower body; a liquid outlet is formed in the bottom of the tower body; an alkaline liquor pool is arranged below the liquid outlet and connected with the spraying layer through a pump by virtue of a pipeline. The desulfurizing tower is provided with the rectifying device, so that the gas distribution state inside the desulfurizing tower can be effectively improved, a flow field in the desulfurizing tower is optimized, and the desulfurization efficiency of the desulfurizing tower is improved. Moreover, due to the external alkaline liquor pool, the alkaline liquor pool is conveniently cleaned, and the alkaline liquor is recycled.
Description
technical field [0001] The invention relates to chemical equipment, in particular to a desulfurization tower used for desulfurization of coal-fired flue gas. Background technique [0002] At present, industrial furnaces produce a large amount of flue gas during operation, which contains a large amount of flue gas particles and harmful gases such as sulfur dioxide. Among them, sulfur dioxide is very harmful to the human body and the environment, and is currently the main source of PM2.5 , seriously polluted the air. Although industrial furnaces are usually equipped with a flue gas separation device to treat the flue gas from the furnace, however, the sulfur dioxide contained in the flue gas cannot be treated, making it difficult for the discharged flue gas to meet environmental protection requirements, and even secondary pollution. Therefore, it is very necessary to equip the industrial furnace with a flue gas desulfurization tower. Contents of the invention [0003] The ...
