Abstract

The invention discloses a novel desulfurization unit which comprises an absorption tower, wherein an air inlet is formed in the inner wall of the left end of the absorption tower; an air inlet pipe isfixedly connected with the inner wall of the air inlet; a heater is fixedly connected to the left end of the air inlet pipe; the input end of the heater is fixedly connected with an air guide tube; aliquid inlet is formed in the inner wall of the left end of the absorption tower; the inner wall of the liquid inlet is fixedly connected with the liquid inlet pipe; a drain outlet and an air outletare respectively formed in the bottom and the top surface of the absorption tower; the inner wall of the drain outlet is fixedly connected with a blow-off pipe; a first circulating mechanism and a second circulating mechanism are arranged on the absorption tower; multiple fixing blocks are fixedly connected onto the inner walls at the left and right ends of the absorption tower; and fillers are fixedly connected onto the multiple fixing blocks. According to novel desulfurization unit disclosed by the invention, the desulfurization effect is excellent, the desulfurization efficiency is high, the flue gas can reach the emission standard, and environmental protection is facilitated.

Description

technical field [0001] The invention relates to the technical field of flue gas purification, in particular to a novel desulfurization device. Background technique [0002] Desulfurization, generally refers to the process of removing sulfur from fuel before combustion and desulfurization before flue gas discharge. It is one of the important technical measures to prevent and control air pollution. [0003] At present, there are generally three desulfurization methods: pre-combustion, in-combustion and post-combustion desulfurization. With the development of industry and the improvement of people's living standards, the thirst for energy is also increasing, SO in coal-fired flue gas 2 It has become the main cause of air pollution. Reduce SO 2 Pollution has become the top priority of today's atmospheric environment governance. Many flue gas desulfurization processes have been widely used in industry, and it also has important practical significance for the treatment of exha...
