Embodiment Construction
[0026] Such as figure 1 As shown, in the present invention, the flue gas inlet 3 is set at a height of 1 / 3 of the left outer side of the circulating fluidized chamber 1, and the flue gas enters the circulating fluidized chamber 1 at an angle of 30 degrees from bottom to top. There are multiple feeders 5 arranged and installed under the bag filter 9 and connected to each other through pipelines. One end of the pipeline is connected to the fluidization tank 4, and the other end is connected to the Roots blower 10. In the Roots blower 10 Under the action of the desulfurizer, the desulfurizer enters the fluidization tank along the pipeline and fully reacts with the incoming flue gas after being uniformly fluidized in the fluidization tank. The flue gas flows from bottom to top in the circulating fluidization chamber, and the humidifier on the top humidifies the desulfurization agent. The flue gas fully reacts with the humidified desulfurization agent. The light desulfurizer enter...

The invention relates to a dense-phase circulating fluidized flow absorber desulfurization device, in particular to a dense-phase circulating fluidized flow absorber flue gas desulfurization device, which belongs to the field of environmental engineering. The device comprises a circulating fluidized chamber (1), a dense-phase chamber (2), a flue gas inlet (3), a fluidized groove (4), a feeder (5), an elevator (6), a humidifier (7), diversion holes (8), a cloth bag filter (9), a Roots blower (10) and a booster fan (11). The invention aims to solve the problems that the existing dense-phase circulating fluidized desulfurization equipment has higher energy consumption, easy blocking and bed collapse and the like, a tower is divided into two chambers, i.e., the circulating fluidized chamber (1) and the dense-phase chamber (2), and the dense flow absorber and the circulating fluidized bed are combined into a desulfurization tower. The device lengthens the line through which flue gas passes, so that the opportunity of desulfurization is increased, and the efficiency of desulfurization is improved.
Description
technical field [0001] The invention relates to a dense-phase circulating fluidized dry tower flue gas desulfurization device, which belongs to the field of environmental engineering. Background technique [0002] Reducing sulfur dioxide emissions is the focus of environmental protection during the country's "Eleventh Five-Year Plan" period, and it is one of the key links for the iron and steel industry to reduce environmental pollution. The main source of sulfur dioxide pollution in the iron and steel industry is the sintering process, and its emissions account for more than 50% of the total emissions in the iron and steel industry. [0003] The dense coherent tower processing technology developed in recent years has obvious advantages. However, in the existing dense-phase circulating fluidized desulfurization equipment, there is only one chamber in the dense-phase circulating fluidized desulfurization equipment, such as Chinese patent: ZL200720103180.1 "a dense-phase circ...
