Description

TECHNICAL FIELD

[0001] The utility model relates to waste gas desulfurization technical field especially, relates to a multistage spraying type waste gas desulfurization device. BACKGROUND

[0002] With the acceleration of industrialization, the problem of waste gas emission polluting the environment is becoming increasingly serious, especially the emission of sulfur-containing waste gas, which has caused serious threat to the atmospheric environment and human health. Desulfurization technology, as a key means to reduce the content of sulfides in waste gas, is widely used in power, chemical, metallurgical and other industries. The traditional desulfurization device has certain limitations in waste gas treatment efficiency and equipment maintenance convenience, and it is difficult to meet the needs of modern industry for efficient, environmentally friendly and sustainable waste gas treatment. Therefore, it is of great significance to develop a multistage spraying type waste gas desulfurization device that can realize efficient desulfurization, rapid maintenance and simple operation.

[0003] The existing waste gas desulfurization device usually adopts single-stage spraying or fixed filtering structure. The waste gas enters the desulfurization tower through the inlet pipe, contacts with the spraying liquid for desulfurization reaction, and then is discharged through the filtering device. The spraying liquid is usually alkaline solution (such as limestone slurry), which removes sulfides in waste gas through neutralization reaction. The filtering device adopts fixed filter screen or filter plate to intercept particulate matter in waste gas. Although this structure can realize basic desulfurization function, it has certain deficiencies in waste gas treatment efficiency, filtering device maintenance and desulfurization effect uniformity, especially when dealing with high-concentration sulfur-containing waste gas, it is difficult to meet the needs of efficient desulfurization and rapid maintenance.

[0004] However, there is a significant problem in the prior art: the filtering device is easy to be blocked after long time use, and the replacement and maintenance process is complex, which leads to the decrease of desulfurization efficiency and the increase of equipment downtime. Since the filtering device is usually of fixed structure, it needs to be stopped and disassembled during replacement, which not only affects the production efficiency, but also increases the maintenance cost. In addition, the blockage of the filtering device will reduce the waste gas passing speed, further affecting the desulfurization effect, therefore a multistage spraying type waste gas desulfurization device is proposed to solve the above problems.
