Description

technical field [0001] The invention relates to a reaction device used in desulfurization, in particular to a cyclone reaction device. [0002] The present invention also relates to a desulfurization device, in particular to a flue gas desulfurization device comprising the aforementioned cyclone reaction device. Background technique [0003] With the continuous development of social industry, the degree of industrialization is getting higher and higher, the scale of production is expanding, and more and more flue gas is discharged into the atmosphere. Among the various gaseous pollutants that affect air quality, SO 2 The flue gas has the largest quantity and the greatest impact. It causes acid rain, destroys the ecological environment, and affects people's health. Therefore, before these industrial flue gases are discharged into the atmosphere, they all need to be treated, and the most important one is desulfurization treatment. [0004] Currently, if figure 1 and figur...

Problems solved by technology

However, the disadvantages of the current spray desulfurization towers are as follows: firstly, the spray device needs a high-pressure pump to spray out the circulating desulfurization reaction slurry, so a relatively high injection pressure is required, so the energy consumption of the prepared high-pressure pump is relatively high, and it takes a lot of money. A large amount of electric energy causes energy waste; secondly, the nozzles of the spraying device are relatively easy to block, and because the droplets of the sprayed reaction slurry do not have many opportunities to contact the flue gas, and some droplets of the desulfurization reaction slurry do not contact the flue gas at all. It falls without contact, so the flue gas desulfurization efficiency is not high, and the desulfurization effect is not good; in addition, due to the configuration of a relatively multi-layer spray device, the cost is high and the structure is complicated, and additional pulping tanks 511 and sinking tanks 522 are required. Therefore, the overall space occupation is too large and the maintenance cost is relatively high.
