Abstract

The invention discloses a rotational flow reaction device and a flue gas desulfurization device. The rotational flow reaction device comprises a rotational flow shell and at least two rotational flow chambers, wherein each rotational flow chamber is provided with at least one swirler, a circular reaction slurry inlet is formed in the upper portion of each rotational flow chamber, and the lower side of each rotational flow chamber is communicated with a gas uniformizing chamber. Each swirler is a swirl impeller comprising an impeller shell, an impeller center shaft and at least five swirl vanes surrounding the impeller center shaft, wherein the impeller shell is fixed in the corresponding rotational flow chamber, the inner edge of each swirl vane is fixed to the impeller center shaft, and the outer edge of each swirl vane is fixed to the impeller shell. A flue gas flow regulating device is arranged on the top of each rotational flow chamber, can open and close the rotational flow chamber, and is connected with the top of the rotational flow chamber. The rotational flow reaction device is simple in structure, the number of the rotational flow chambers involved in reaction can be selected, the velocity of flue gas can be effectively controlled, flue gas desulfurization effect and degree can be guaranteed, energy can be saved, and environment pollution can be avoided.

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.
