4, the pyramidal structure of dividing plate 4 makes flue gas form backflow, is sprayed by lower floor's spraying layer again, extends the time of staying of flue gas
With gas-to-liquid contact effect.When flue gas flows through conduit 3, due to the circumference uniform distribution of conduit 3, and there is certain inclination angle in the horizontal plane
Degree, so flue gas defines eddy flow, extends the time of staying and is sufficiently mixed.Flue gas quilt when gas-liquid assembles plate 2
Stop and collect to centre, the flue gas of the angle of inclination Ye Shi edges of gas-liquid aggregation plate 2 defines backflow, when extending stop
Between.The sprayed slurry that upper strata spraying layer is provided is blocked when assembling plate 2 down through gas-liquid, in gas-liquid aggregation plate 2 edge certainly
By falling and being formed one layer of liquid curtain, flue gas enhances gas-to-liquid contact effect when passing through liquid curtain, so as to improve mass-transfer efficiency.Serosity
Continue to stop that, so as to complete the isolation of serosity, the cutting angle in the exit of conduit 3 is further carried by the top edge of conduit 3 downwards
High isolation effect.The serosity of isolation is collected by dividing plate 4, is converged in dividing plate and is enclosed " W " the type region that cone-plate is constituted with coaming plate two
Bottom, and the no matter size of serosity amount, can keep the derivation absorption tower with metastable flow rate and direction liquid outlet 5, effectively
Prevent deposition clogging.4.5 meters of this absorption tower diameter, using the conduit 4 of 10 a diameter of 460mm, cutting angle γ is
45 °, angle of inclination μ is 30 °, and gas-liquid aggregation plate 3 tilt angle alpha is 5 °, and the angle of inclination δ of coaming plate 8 is 30 °, the angle of inclination of dividing plate 4
β is 10 °, and Jing computers simulation gas flowfield is analyzed and actual motion, can effectively completely cut off collection liquid, the very big flue gas that extends and stop
Time is simultaneously sufficiently mixed, and improves gas-liquid mass transfer effect.Absorption tower effectively reduces tower body high without the need for arranging equal device of air again
Degree.
Preferred embodiment of the present utility model is the foregoing is only, but embodiment and accompanying drawing are not for limiting this practicality
New, any to be familiar with this those skilled in the art, in without departing from spirit and scope of the present utility model, any modification for being made, equivalent are replaced
