Description

Technical Field

[0001] The invention belongs to the technical field of flue gas purification and relates to a spray dust removal and desulfurization tower. Background Art

[0002] With the acceleration of industrialization and the continuous growth of energy consumption, the problem of air pollution is becoming increasingly serious. Among them, sulfur dioxide emissions are one of the main factors leading to environmental problems such as acid rain and haze. As the main sources of sulfur dioxide emissions, thermal power generation, steel smelting, chemical production and other industries have made flue gas purification a top priority in environmental protection work. Therefore, developing efficient and reliable flue gas purification technology to reduce the emission of harmful gases such as sulfur dioxide is an important way to ensure sustainable environmental development.

[0003] Traditional flue gas purification technologies, such as dry desulfurization and semi-dry desulfurization, can reduce sulfur dioxide emissions to a certain extent, but they have problems such as low desulfurization efficiency, high energy consumption, and difficult by-product treatment. Especially when dealing with high-concentration sulfur dioxide flue gas, the limitations of traditional technologies are more obvious. As an advanced flue gas purification equipment, the spray dust removal desulfurization tower has significant technical advantages. First, by spraying slurry, the sulfur dioxide in the flue gas reacts with the alkaline substances in the slurry to generate sulfates or sulfites, thereby achieving efficient desulfurization. This desulfurization method is not only efficient, but also capable of handling high-concentration sulfur dioxide flue gas. Secondly, the spray dust removal desulfurization tower has strong adaptability and is suitable for flue gas treatment systems of various sizes, whether it is a large thermal power plant or a small industrial boiler, it can achieve an ideal desulfurization effect.

The overall structure is scientific, reasonable, simple and compact, and is widely used in flue gas purification operations.

[0005] When the above-mentioned desulfurization and dust removal spray tower is actually used, since the flue gas is first sprayed by two spray layers after entering the tower body, the sprayed liquid itself has a certain range, and the contact between the sprayed liquid and the flue gas is limited, resulting in a weak dust reduction effect under direct spraying.
