Desulfurizer

Abstract

The invention discloses a desulfurizer. A desulfurizing tower is provided with a dust removing chamber, an atomizing spray chamber, a sulfide absorption chamber and a wastewater collecting chamber from top to bottom, wherein the dust removing chamber, the atomizing spray chamber, the sulfide absorption chamber and the wastewater collecting chamber are communicated in sequence, and the wastewater collecting chamber is communicated with a circulating water device; the desulfurizer is further provided with the circulating water device, the circulating water device comprises a circulating water extraction device which is communicated with a circulating water condensing device, a water pump is communicated with the atomizing spray chamber through multiple drain pipes, and a first drain valve isarranged on each drain pipe; an electrostatic precipitator, an air filter and an electrostatic eliminator are arranged in the dust removing chamber and mounted inside the dust removing chamber. By means of arrangement of the dust removing chamber, particulate matter such as dust and the like contained in flue gas can be removed efficiently.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a desulfurization device. Background technique [0002] The flue gas emitted by coking plants and brick factories contains a large amount of sulfur dioxide, which is very harmful to the human body and the environment, and is currently the main source of pm2.5. [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 exhaust gas from various bo...

AI Technical Summary

Problems solved by technology

Since the flue gas will contain a large amount of particulate matter, such as dust, it is necessary to remove the dust in the flue gas to facilitate the desulfurization of the flue gas. Spraying, and a large amount of waste water will be generated after spraying, if not utilized, it is very wasteful and not environmentally friendly
